# Appointment Metadata Create form

Source: https://docs.canvasmedical.com/sdk/appointment-metadata-create-form-effect/

##  Overview 
This allows developers to dynamically display additional fields when scheduling an appointment.
    ```python
    from canvas_sdk.effects.appointments_metadata import (
        FormField,
        InputType,
        AppointmentsMetadataCreateFormEffect,
    )
    AppointmentsMetadataCreateFormEffect(form_fields=[
        FormField(
            key='status',
            label='Status',
            type=InputType.SELECT,
            required=False,
            editable=True,
            options=["open", "close"],
            value=""
        ),
    ])
    ```
##  Structure 
###  **FormField**
A FormField consists of the following properties:
####  Attributes 
Attribute| Type| Description  
---|---|---  
`key`| `str`| unique identifier of the field - appointment metadata key  
`label`| `str`| the label that will be displayed on the field  
`type`| `InputType`| the type of the input - TEXT, SELECT, DATE.  
`required`| `bool`| if the input is required.  
`editable`| `bool`| if the input can be editabled.  
`options`| `list[str]`| possible options for when the input type is set to "SELECT"  
`value`| `str`| default value for the field  
###  **AppointmentsMetadataCreateFormEffect**

# Caching API

Source: https://docs.canvasmedical.com/sdk/caching/

The Canvas SDK provides a caching API for plugin developers to store and retrieve temporary data efficiently.
For persistent storage of plugin data, use instead the [Custom Data](/sdk/custom-data/) features.
* * *
##  Getting the Cache Client 
To use the cache in your plugin, simply import and call:
    ```python
    from canvas_sdk.caching.plugins import get_cache
    cache = get_cache()
    ```
* * *
##  TTL and Expiration 
  - By default, all cached keys expire after **14 days**.
  - You can set a shorter TTL when writing to the cache via the `timeout_seconds` parameter.
  - If a longer TTL is provided, a `CachingException` will be raised.
* * *
##  Supported Methods 
###  `get(key: str, default: Any | None = None) -> Any`
Retrieve a value from the cache:
    ```python
    user = cache.get("key")
    ```
You can specify a fallback if the key doesn't exist:
    ```python
    user = cache.get("key", default="default_value")
    ```
* * *
###  `set(key: str, value: Any, timeout_seconds: int | None = None) -> None`
Store a value in the cache:
    ```python
    cache.set("key", {"name": "Alice"}, timeout_seconds=600)
    ```
* * *
###  `get_or_set(key: str, default: Any | Callable, timeout_seconds: int | None = None) -> Any`
Fetch a value or set it if not present:
    ```python
    value = cache.get_or_set("key", default=lambda: compute_value(), timeout_seconds=300)
    ```
* * *
###  `set_many(data: dict[str, Any], timeout_seconds: int | None = None) -> list[str]`
Set multiple values at once:
    ```python
    cache.set_many({
        "key1": {"name": "Alice"},
        "key2": {"name": "Bob"}
    }, timeout_seconds=900)
    ```
* * *
###  `get_many(keys: Iterable[str]) -> dict[str, Any]`
Fetch multiple values in one operation:
    ```python
    users = cache.get_many(["key1", "key2"])
    ```
* * *
###  `delete(key: str) -> None`
Remove a key from the cache:
    ```python
    cache.delete("key")
    ```
* * *
###  `__contains__(key: str) -> bool`
Check if a key exists in cache:
    ```python
    if "key" in cache:
        ...
    ```

        allowed_note_types=["100", "101"]
    ).create()
    # Update an existing event
    Event(
        event_id="event-uuid",
        title="Updated Meeting Title",
        starts_at=datetime(2025, 1, 15, 15, 0),
        ends_at=datetime(2025, 1, 15, 16, 0)

# Canvas CLI

Source: https://docs.canvasmedical.com/sdk/canvas_cli/

##  Getting Started 
###  Installation using `pip`
To install the Canvas CLI using `pip`, execute `pip install canvas`. Python 3.11, 3.12, or 3.13 is required.
To upgrade the Canvas CLI if you installed using `pip`, execute `pip install --upgrade canvas`.
###  Installation using `uv`
To install the Canvas CLI using `uv`, execute `uv tool install canvas`. `uv` will find or procure an acceptable Python version.
To upgrade the Canvas CLI if you installed using `uv`, execute `uv tool upgrade canvas`.
###  Configuration and Authenticating to Your Canvas Instance 
Create a file `~/.canvas/credentials.ini` with sections for each of your Canvas instance subdomains, and add client_id and client_secret credentials to each section. For example, if your Canvas instance url is `https://buttered-popcorn.canvasmedical.com/`, you would have a section `[buttered-popcorn]` with key-value pairs for `client_id` and `client_secret`.
> **Info:** **Getting Credentials:** Learn how to get register a client_id and client_secret [here](/api/customer-authentication/#registering-a-third-party-application-on-canvas).  
> The Canvas CLI uses OAuth, just like the FHIR API.
**Example:**
    ```ini
    [buttered-popcorn]
    client_id=butter
    client_secret=salt
    [dev-buttered-popcorn]
    client_id=devbutter
    client_secret=devsalt
    is_default=true
    [localhost]
    client_id=localclientid
    client_secret=localclientsecret
    ```
You can define your default host with `is_default=true`. If no default is explicitly defined, the Canvas CLI will use the first instance in the file as the default for each of the CLI commands.
**You are now ready to use the Canvas CLI**
##  Update Notifications 
The Canvas CLI automatically checks [PyPI](https://pypi.org/project/canvas/) for newer versions. If an update is available, a notice is printed to standard error after the command output:
    ```shell
    [notice] A newer version of canvas is available (0.112.0 → 0.113.0). Upgrade with: pip install --upgrade canvas
    ```
  - The check runs at most once every 12 hours; the result is cached locally to avoid unnecessary network requests.
  - Because the notice is printed to standard error, it will not interfere with piped or redirected command output.
  - To disable update checks, set the environment variable `CANVAS_NO_UPDATE_CHECK=1`.
##  Usage 
    ```console
    $ canvas [OPTIONS] COMMAND [ARGS]...
    ```
**Options** :
  - `--version`
  - `--help`: Show this message and exit.
##  Commands

  - `config set`: Set plugin variables on a Canvas instance
###  `canvas init`
Create a new plugin.
**Usage** :
    ```console
    $ canvas init [OPTIONS]
    ```
**Options** :
  - `--help`: Show this message and exit.
###  `canvas install`
Install a plugin into a Canvas instance.
**Usage** :
    ```console
    $ canvas install [OPTIONS] PLUGIN_NAME
    ```
**Arguments** :
  - `PLUGIN_NAME`: Path to plugin to install [required]
**Options** :
  - `--variable TEXT`: Non-sensitive variables to set, e.g. Key=value
  - `--secret TEXT`: Sensitive variables to set (treated as sensitive=true), e.g. Key=value
  - `--enable / --disable`: Install the plugin in an enabled or disabled state. Defaults to `--enable`.
  - `--host TEXT`: Canvas instance to connect to
  - `--help`: Show this message and exit.
**Notes** :
Before uploading, `canvas install` runs the same pre-flight validation as `canvas validate`:
  - Manifest validation (schema, tags, handler resolution)
  - Static lint (scans your source for sandbox-forbidden constructs and Custom Data mistakes)
  - Sandbox-load validation (imports every handler in the sandbox)
If the static lint reports an error, or any handler fails to load — for example, due to a disallowed import like `subprocess` — the install aborts before the plugin is built or uploaded, so it never reaches your instance. Run `canvas validate` first for detailed per-handler results.
The CLI automatically excludes common build artifacts from the plugin bundle:
  - `__pycache__` directories
  - `*.pyc` and `*.pyo` files
  - `node_modules` directories
  - Hidden files and directories (e.g., `.git`, `.env`)
To exclude additional files, create a `.canvasignore` file in your plugin directory. This file follows the same syntax as [.gitignore](https://git-scm.com/docs/gitignore).
Example
    ```md
    # Exclude test files
    test_*.py
    ```

    ```
**Arguments** :
  - `PLUGIN_NAME`: Path to plugin to validate [required]
**Options** :

This command runs full pre-flight validation combining:
  1. **Manifest validation** — Schema checks, tag validation, handler resolution, and unreferenced handler warnings (everything `validate-manifest` does).
  2. **Static lint** — Scans the plugin's source for sandbox-forbidden constructs and Custom Data mistakes before any code runs.
  3. **Sandbox-load validation** — Imports every handler the way the plugin runner will, catching violations that would otherwise surface only at runtime on the instance.
####  Static lint 
Before it loads any handlers, `canvas validate` scans every `.py` file in the plugin — skipping directories like `tests`, `build`, and `dist` _within_ the plugin — for patterns that compile cleanly but fail, or silently misbehave, once your code runs on the instance. Each finding is reported with a rule code in brackets. Warnings are printed but do not block validation; any error fails the command and exits with code 1.
    ```console
    $ canvas validate my_plugin
      ⚠ my_plugin/handlers/protocol.py:42  [custom-model-id-vs-dbid]  Widget.objects.filter(id=…) — CustomModels use `dbid` as their primary key (only core SDK models have `id`). Use `dbid=…` instead.
    These issues will fail on the instance (sandbox / Custom Data):
      ✗ my_plugin/handlers/protocol.py:18  [setattr-blocked]  `setattr()` is blocked by the sandbox. Use direct attribute assignment (`obj.attr = value`) instead.
    ```
**Sandbox constructs (errors).** These compile under RestrictedPython but are rejected when a handler runs on the instance, so a plain sandbox load can miss them. See [Sandboxing and Allowed Imports](/sdk/sandboxing-and-allowed-imports/#forbidden-constructs) for the full list and the allowed alternatives.
Rule code| Flags  
---|---  
`setattr-blocked`| `setattr(obj, "x", value)` — use `obj.x = value`  
`delattr-blocked`| `delattr(obj, "x")` — use `del obj.x`  
`bytearray-blocked`| `bytearray(...)` — use `bytes` for binary data  
`type-blocked`| Any call to `type()`. It is absent from the sandbox builtins, so even the one-argument `type(x)` raises `NameError` — use `isinstance(x, SomeClass)` or `x.__class__.__name__`, and declare classes with `class …:` rather than `type(name, bases, dict)`  
`augmented-subscript`| Augmented assignment on a subscript, e.g. `d[k] += v` — rewrite as `d[k] = d[k] + v`  
`augmented-attribute`| Augmented assignment on an attribute, e.g. `obj.attr += v` — rewrite as `obj.attr = obj.attr + v`  
`@dataclass(frozen=True)` and `@dataclass(slots=True)` load and run fine in the sandbox and are intentionally not flagged.
**Custom Data (errors).** Both leave tables silently uncreated, so queries fail at runtime. See [Custom Models](/sdk/custom-data-custom-models/) and the [Quick Start](/sdk/custom-data-quick-start/) for setup.
Rule code| Flags  
---|---  
`custom-model-wrong-dir`| A `CustomModel` subclass defined outside `<plugin>/models/` — Canvas only loads models from that directory  
`missing-custom-data-block`| CustomModels are present but the manifest has no `custom_data` block (an empty block counts as missing — it must be non-empty)  
**Custom Data (warnings).** These don't block validation but usually indicate a bug:
Rule code| Flags  
---|---  
`custom-model-id-vs-dbid`| `.filter(id=…)` / `.get(id=…)` on a local CustomModel — CustomModels key on `dbid`, not `id`. Use `dbid=…`  
`lazy-fk-string-ref`| A `ForeignKey`/`OneToOneField`/`ManyToManyField` with a string reference to a CustomModel defined in this plugin — import the class and pass it directly  
####  Sandbox-load validation 
After the static lint passes, sandbox-load validation executes each handler module in the plugin sandbox to catch:
  - **Disallowed imports** — Modules like `subprocess`, `socket`, or `os` that are blocked by the sandbox.
  - **RestrictedPython compile-time errors** — Syntax or constructs that RestrictedPython cannot compile.
  - **Import errors** — Missing dependencies or broken imports.
For each handler, the output shows whether it loaded successfully:
    ```console
    $ canvas validate my_plugin
    Loading 2 handler(s) in the sandbox:
      ✓ my_plugin.handlers.events:MyHandler
      ✗ my_plugin.handlers.api:APIHandler
        ImportError: 'subprocess' is not an allowed import
    1 of 2 handler(s) failed to load in the sandbox.
    ```
The command exits with code 1 if any handler fails validation.
####  Limitations 
A passing `canvas validate` confirms that handlers import cleanly under the sandbox — it does not guarantee the plugin is fully sandbox-clean. RestrictedPython checks attribute and item access inside `compute()` at request time, not at import time, so violations during handler execution won't be caught by this command.
> **Info:** `canvas install` runs this same static lint and sandbox-load validation before uploading, so violations are caught before they reach your instance.
###  `canvas validate-manifest`
Validate the Canvas Manifest json file.
**Usage** :
    ```console
    $ canvas validate-manifest [OPTIONS] PLUGIN_NAME
    ```
**Arguments** :
  - `PLUGIN_NAME`: Path to plugin to validate [required]
**Options** :
  - `--help`: Show this message and exit.
**Validations performed** :
  1. **Schema validation** — Checks that `CANVAS_MANIFEST.json` contains all required fields and valid values.
  2. **Handler resolution** — Verifies that every handler class declared in the manifest (`protocols`, `applications`, and `handlers`) resolves to a file the plugin runner can find at runtime.
####  Handler resolution and directory layout 
The plugin runner loads handlers by mapping dotted module paths to files relative to the plugin's install directory. For a plugin named `my_plugin` with a handler class `my_plugin.handlers.events:MyHandler`, the runner expects `handlers/events.py` inside the plugin directory — the directory containing `CANVAS_MANIFEST.json`.
A common mistake is placing `CANVAS_MANIFEST.json` in a parent directory above the plugin package. This passes schema validation and works locally, but fails at runtime with `ModuleNotFoundError` — the handler files are nested one level too deep.
**Correct layout:**
    ```text
    my_plugin/
    ├── CANVAS_MANIFEST.json   # ← manifest inside the package
    ├── handlers/
    │   └── events.py
    └── ...
    ```
**Incorrect layout:**
    ```text
    project/
    ├── CANVAS_MANIFEST.json   # ← manifest above the package (wrong!)
    └── my_plugin/
        └── handlers/
            └── events.py
    ```
If `validate-manifest` detects handlers that won't resolve, it reports which classes are affected and the file paths the runner expects:
    ```console
    Error: these handler classes won't be found by the plugin runner with the current directory layout:
      - my_plugin.handlers.events:MyHandler
        runner expects: my_plugin/handlers/events.py
    CANVAS_MANIFEST.json must live inside the plugin's package directory (the directory whose name matches the manifest "name"), alongside the handler packages — not in a parent directory above them.
    ```
> **Info:** `canvas install` runs manifest validation, the static lint, and sandbox-load validation before uploading. Use `canvas validate` for a full pre-flight check with detailed per-handler output.
###  `canvas logs`
Subscribes to a log stream and prints to your console. Optionally fetches historical logs first.
**Usage** :
    ```console
    $ canvas logs [OPTIONS]
    ```
**Options** :
  - `--host TEXT`: Canvas instance to connect to
  - `--help`: Show this message and exit.
  - `--since TEXT`: Lookback window (e.g. '24h', '2h30m'). Mutually exclusive with –start/–end.
  - `--start TEXT`: Start time (ISO/RFC3339) or 'now'.
  - `--end TEXT`: End time (ISO/RFC3339) or 'now'. Defaults to now if start is provided.
  - `--no-follow`: Historical only; do not stream live logs.
  - `--level TEXT`: Repeatable. –level ERROR –level WARN
  - `--source TEXT`: Filter by source/service.
  - `--plugin TEXT`: Repeatable. –plugin foo –plugin bar.
  - `--handler TEXT`: Repeatable. Qualified handler name (e.g. my_plugin.handlers.Foo).
  - `--page-size INTEGER`: Fetch size per page (historical). [default: 200]
  - `--limit INTEGER`: Max historical logs to print.
  - `--all`: Fetch all pages until exhausted (historical).
  - `--interactive`: After each page, prompt to load more.
  - `--cursor TEXT`: Resume token from a previous run.
  - `--help`: Show this message and exit.
###  `canvas config list`
List plugin variables on a Canvas instance. Each variable is rendered as `[set]` or `[not set]`, with a `(sensitive)` annotation for sensitive variables. Values themselves are never displayed — to read a value, use the Django Admin UI (gated by managing-user permissions).
**Usage** :
    ```console
    $ canvas config list [OPTIONS] PLUGIN
    ```
**Example output** :
    ```console
    $ canvas config list my_plugin
      API_TOKEN  [set]  (sensitive)
      LOG_LEVEL  [not set]
    ```
**Arguments** :
  - `PLUGIN`: Plugin name to list variables for
**Options** :
  - `--host TEXT`: Canvas instance to connect to
  - `--help`: Show this message and exit.
**Example Output** :
    ```console
    $ canvas config list my_plugin
      API_TOKEN = [set]  (sensitive)
      WEBHOOK_URL = [set]
      DEBUG_MODE = [not set]
    ```
###  `canvas config set`
Set (or update) one or more plugin variables on a Canvas instance. Each variable must already be declared in the plugin's `CANVAS_MANIFEST.json`. Pass one or more `KEY=value` pairs as positional arguments.
**Usage** :
    ```console
    $ canvas config set [OPTIONS] PLUGIN VARIABLES...
    ```
**Examples** :
Set a single variable:
    ```console
    $ canvas config set my_plugin API_TOKEN=your_api_token_value
    ```
Set multiple variables in one call:
    ```console
    $ canvas config set my_plugin API_TOKEN=abc123 LOG_LEVEL=info
    ```
Set a variable whose value is a list with one entry per line — for example a redirect allowlist (see the [Redirect effect](/sdk/effect-redirect/)). The value is newline-delimited (not comma-separated), so use your shell's newline quoting to preserve the line breaks. In bash/zsh, ANSI-C quoting (`$'…'`) turns `\n` into a real newline:
    ```console
    $ canvas config set my_plugin $'REDIRECT_ALLOWLIST_INTERNAL=/panel\n/patient'
    ```
**Arguments** :
  - `PLUGIN`: Plugin name to set variables for
  - `VARIABLES...`: Variables to set, e.g. Key=value
**Options** :
  - `--host TEXT`: Canvas instance to connect to
  - `--help`: Show this message and exit.
> Whether each value is treated as sensitive is determined by the plugin's `CANVAS_MANIFEST.json` (`variables: [{name, sensitive}]`) — `canvas config set` does not change the sensitive flag.

The Canvas SDK AWS S3 client provides a simple interface for interacting with Amazon S3 storage, including uploading, downloading, listing, and deleting objects, as well as generating presigned URLs for temporary access.
##  Requirements 
  - **AWS Access Key ID** : Your AWS access key
  - **AWS Secret Access Key** : Your AWS secret key
  - **AWS Region** : The region where your bucket is located (e.g., `us-east-1`)
  - **S3 Bucket Name** : The name of your S3 bucket
##  Imports 
The AWS S3 client is included in the Canvas SDK. Import the necessary components:
    ```python
    from canvas_sdk.clients.aws import S3, Credentials, S3Item
    ```
Or import from specific modules:
    ```python
    from canvas_sdk.clients.aws.libraries import S3
    from canvas_sdk.clients.aws.structures import Credentials, S3Item
    ```
##  Initialize the Client 
    ```python
    from canvas_sdk.clients.aws import S3, Credentials
    credentials = Credentials(
        key="your_aws_access_key_id",
        secret="your_aws_secret_access_key",
        region="us-east-1",
        bucket="your-bucket-name"
    )
    client = S3(credentials)
    ```
##  Check if Client is Ready 
    ```python
    if client.is_ready():
        print("S3 client is configured and ready")
    else:
        print("Missing credentials")
    ```
##  Upload a Text File 
    ```python
    from canvas_sdk.clients.aws import S3, Credentials
    credentials = Credentials(
        key="your_access_key",
        secret="your_secret_key",
        region="us-east-1",
        bucket="my-bucket"
    )
    client = S3(credentials)
    # Upload text content
    response = client.upload_text_to_s3("path/to/file.txt", "Hello, World!")
    if response and response.status_code == 200:
        print("Text file uploaded successfully!")
    ```
##  Upload a Binary File 
    ```python
    # Upload binary content (e.g., an image)
    with open("local_image.png", "rb") as f:
        binary_data = f.read()
    response = client.upload_binary_to_s3(
        "images/uploaded_image.png",
        binary_data,
        "image/png"
    )
    if response and response.status_code == 200:
        print("Binary file uploaded successfully!")
    ```
##  Download a File 
    ```python
    response = client.access_s3_object("path/to/file.txt")
    if response:
        content = response.content
        print(f"Downloaded content: {content.decode('utf-8')}")
    ```
##  List Objects in Bucket 
    ```python
    # List all objects with a prefix
    items = client.list_s3_objects("documents/")
    if items:
        for item in items:
            print(f"Key: {item.key}, Size: {item.size} bytes, Modified: {item.last_modified}")
    ```
##  Delete an Object 
    ```python
    response = client.delete_object("path/to/file.txt")
    if response and response.status_code == 204:
        print("Object deleted successfully!")
    ```
##  Generate a Presigned URL 
    ```python
    # Generate a URL valid for 1 hour (3600 seconds)
    url = client.generate_presigned_url("path/to/file.txt", expiration=3600)
    if url:
        print(f"Presigned URL: {url}")

##  Complete Plugin Example 
Here's a complete example of using the S3 client in a Canvas plugin:
    ```python
    from http import HTTPStatus
    from canvas_sdk.clients.aws import S3, Credentials
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, PlainTextResponse, Response
    from canvas_sdk.handlers.simple_api import Credentials as APICredentials, SimpleAPI, api
    class S3Handler(SimpleAPI):
        """Simple API handler for S3 operations."""
        def authenticate(self, credentials: APICredentials) -> bool:
            return True
        def _s3_client(self) -> S3:
            """Create S3 client from plugin secrets."""
            return S3(
                Credentials(
                    key=self.secrets["S3Key"],
                    secret=self.secrets["S3Secret"],
                    region=self.secrets["S3Region"],
                    bucket=self.secrets["S3Bucket"],

                items = client.list_s3_objects("")
                content = [{"key": p.key, "size": p.size} for p in items]
                return [JSONResponse(content, status_code=HTTPStatus.OK)]
            return []
        @api.get("/download/<file_key>")
        def download_file(self) -> list[Response | Effect]:
            """Download a file by key."""
            file_key = self.request.path_params["file_key"]
            client = self._s3_client()
            if client.is_ready() and file_key:
                response = client.access_s3_object(file_key)
                return [Response(response.content, status_code=HTTPStatus.OK)]
            return []

        def upload_file(self) -> list[Response | Effect]:
            """Upload a file."""
            file_key = self.request.path_params["file_key"]
            client = self._s3_client()
            content = self.request.body
            content_type = self.request.content_type
            if client.is_ready() and file_key:
                if content_type == "text/plain":
                    response = client.upload_text_to_s3(file_key, content.decode("utf-8"))
                else:
                    response = client.upload_binary_to_s3(file_key, content, content_type)
                return [Response(response.content, status_code=response.status_code)]
            return []
        @api.delete("/delete/<file_key>")
        def delete_file(self) -> list[Response | Effect]:
            """Delete a file by key."""
            file_key = self.request.path_params["file_key"]
            client = self._s3_client()
            if client.is_ready() and file_key:
                response = client.delete_object(file_key)
                return [Response(response.content, status_code=HTTPStatus.OK)]
            return []
        @api.get("/presigned/<file_key>")
        def get_presigned_url(self) -> list[Response | Effect]:
            """Generate a presigned URL for temporary access."""
            file_key = self.request.path_params["file_key"]
            client = self._s3_client()
            if client.is_ready() and file_key:
                url = client.generate_presigned_url(file_key, 3600)  # 1 hour
                return [PlainTextResponse(url, status_code=HTTPStatus.OK)]
            return []
    ```
##  Error Handling 
The S3 client methods return `None` when credentials are not ready. For list operations, an `Exception` is raised if S3 returns an error status code.
    ```python
    # Check credentials before operations
    if not client.is_ready():
        print("S3 credentials are not configured")
        return
    # Handle list errors
    try:
        items = client.list_s3_objects("prefix/")
    except Exception as e:
        print(f"S3 error: {e}")
    # Check response status for uploads/downloads
    response = client.upload_text_to_s3("file.txt", "content")
    if response:
        if response.status_code == 200:
            print("Upload successful")
        else:
            print(f"Upload failed with status {response.status_code}")
    else:
        print("Credentials not ready")
    ```
##  AWS Signature V4 Authentication 
The S3 client implements AWS Signature Version 4 for request authentication. This is handled automatically - you only need to provide valid credentials. The client:
  - Signs all requests with HMAC-SHA256
  - Generates proper canonical requests
  - Handles date/time formatting for AWS
  - Supports presigned URLs for temporary access

# Canvas FHIR

Source: https://docs.canvasmedical.com/sdk/clients-canvas-fhir/

The Canvas SDK FHIR client provides a simple interface for interacting with the [Canvas FHIR API](/api/), supporting CRUD operations on FHIR resources such as Coverages, DocumentReferences, AllergyIntolerances, and more. It handles OAuth client credentials authentication and token caching automatically.
##  Requirements 
  - **Canvas FHIR Client ID** : An OAuth client ID for your Canvas environment
  - **Canvas FHIR Client Secret** : The corresponding OAuth client secret
These credentials should be stored as [plugin secrets](/sdk/secrets/) and grant access to the Canvas FHIR API for your environment.
##  Imports 
The Canvas FHIR client is included in the Canvas SDK. Import the client:
    ```python
    from canvas_sdk.clients.canvas_fhir import CanvasFhir
    ```
##  Initialize the Client 
    ```python
    # Declare these secrets in the CANVAS_MANIFEST.json and set the values on the
    # plugin configuration page.
    client_id = self.secrets["CANVAS_FHIR_CLIENT_ID"]
    client_secret = self.secrets["CANVAS_FHIR_CLIENT_SECRET"]
    client = CanvasFhir(client_id, client_secret)
    ```
On initialization, the client will:
  1. Authenticate using the OAuth client credentials flow against your Canvas environment's token endpoint.
  2. Cache the access token using the plugin cache system, keyed by `client_id`, with automatic expiration.
  3. Determine the FHIR API base URL from the environment's `CUSTOMER_IDENTIFIER` setting (e.g., `https://fumage-{CUSTOMER_IDENTIFIER}.canvasmedical.com`).
##  CanvasFhir 
The main class for interacting with the Canvas FHIR API.
###  Constructor 
    ```python
    CanvasFhir(client_id: str, client_secret: str)
    ```
Parameter| Type| Description  
---|---|---  
`client_id`| `str`| OAuth client ID for the Canvas API  
`client_secret`| `str`| OAuth client secret  
###  Methods 
####  `search(resource_type: str, parameters: dict) -> dict`
Search for FHIR resources matching the given parameters.
    ```python
    # Search for a patient's allergy intolerances
    results = client.search("AllergyIntolerance", {"patient": "Patient/abc123"})
    for entry in results.get("entry", []):
        resource = entry["resource"]
        print(f"Allergy: {resource['code']['coding'][0]['display']}")
    ```
Parameter| Type| Description  
---|---|---  
`resource_type`| `str`| FHIR resource type (e.g., `Patient`, `Coverage`)  
`parameters`| `dict`| Search parameters as key-value pairs  
**Returns:** FHIR Bundle `dict` containing matching resources.
**Raises:** `requests.HTTPError` if the API returns an error status code.
####  `read(resource_type: str, resource_id: str) -> dict`
Read a single FHIR resource by its ID.
    ```python
    # Read a specific resource by ID
    allergy = client.read("AllergyIntolerance", "allergy-id-123")
    print(f"Status: {allergy['clinicalStatus']['coding'][0]['code']}")
    ```
Parameter| Type| Description  
---|---|---  
`resource_type`| `str`| FHIR resource type  
`resource_id`| `str`| ID of the resource to read  
**Returns:** FHIR resource `dict`.
**Raises:** `requests.HTTPError` if the API returns an error status code.
####  `create(resource_type: str, data: dict) -> dict`
Create a new FHIR resource.
    ```python
    # Create a new Coverage resource
    coverage = client.create("Coverage", {
        "resourceType": "Coverage",
        "status": "active",
        "beneficiary": {"reference": "Patient/abc123"},
        "payor": [{"reference": "Organization/org-456"}],
    })
    print(f"Created Coverage: {coverage['id']}")
    ```
Parameter| Type| Description  
---|---|---  
`resource_type`| `str`| FHIR resource type  
`data`| `dict`| FHIR resource data to create  
**Returns:** Created FHIR resource `dict` (including server-assigned `id`).
**Raises:** `requests.HTTPError` if the API returns an error status code.
####  `update(resource_type: str, resource_id: str, data: dict) -> dict`
Update an existing FHIR resource.
    ```python
    # Update an existing resource
    updated = client.update("Coverage", "coverage-id-789", {
        "resourceType": "Coverage",
        "id": "coverage-id-789",
        "status": "cancelled",
        "beneficiary": {"reference": "Patient/abc123"},
        "payor": [{"reference": "Organization/org-456"}],

`resource_type`| `str`| FHIR resource type  
`resource_id`| `str`| ID of the resource to update  
`data`| `dict`| Complete FHIR resource data  
**Returns:** Updated FHIR resource `dict`.
**Raises:** `requests.HTTPError` if the API returns an error status code.
##  Authentication 
The client uses the OAuth 2.0 client credentials flow to authenticate with the Canvas API. Token management is handled automatically:
  - On first use, the client exchanges the `client_id` and `client_secret` for an access token via the Canvas token endpoint.
  - The token is cached using the plugin cache system with the key `canvas_fhir_credentials_{client_id}`.
  - The cached token expires 60 seconds before the actual token expiration to avoid using stale credentials.
  - Subsequent requests reuse the cached token until it expires.
##  Error Handling 
The Canvas FHIR client uses `raise_for_status()` on all HTTP responses, which raises `requests.HTTPError` for non-successful status codes.
    ```python
    from requests import HTTPError
    try:
        result = client.read("Patient", "nonexistent-id")
    except HTTPError as e:
        print(f"HTTP {e.response.status_code}: {e.response.text}")
    ```
##  Complete Plugin Example 
Here's a complete example of using the Canvas FHIR client in an ActionButton handler:
    ```python
    from canvas_sdk.clients.canvas_fhir import CanvasFhir
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers.action_button import ActionButton
    from logger import log
    class FhirRequestHandler(ActionButton):
        """Handler that queries the FHIR API when a button is clicked."""
        BUTTON_TITLE = "Trigger FHIR Request"
        BUTTON_KEY = "TRIGGER_FHIR_REQUEST"
        BUTTON_LOCATION = ActionButton.ButtonLocation.CHART_SUMMARY_ALLERGIES_SECTION
        def handle(self) -> list[Effect]:
            """Handle the button click."""
            client_id = self.secrets["CANVAS_FHIR_CLIENT_ID"]
            client_secret = self.secrets["CANVAS_FHIR_CLIENT_SECRET"]
            patient_id = self.event.target.id
            client = CanvasFhir(client_id, client_secret)
            # Search for the patient's allergy intolerances
            search_response = client.search(
                "AllergyIntolerance",
                {"patient": f"Patient/{patient_id}"},
            )
            log.info(f"Search: {search_response}")
            # Read the first result
            first_entry = search_response["entry"][0]["resource"]
            read_response = client.read("AllergyIntolerance", first_entry["id"])
            log.info(f"Read: {read_response}")

            if time.time() - start_time > timeout_seconds:
                raise TimeoutError(f"Processing timed out after {timeout_seconds}s")
            time.sleep(poll_interval)

# LLMs

Source: https://docs.canvasmedical.com/sdk/clients-llms/

The Canvas SDK LLMs client provides a unified interface for interacting with multiple Large Language Model (LLM) providers including OpenAI (GPT Models), Anthropic (Claude), and Google (Gemini). It supports text conversations, file attachments (images, PDFs, text), and structured JSON output.
##  Requirements 
Depending on which LLM provider you use:
  - **OpenAI** : API key from https://platform.openai.com/api-keys
  - **Anthropic** : API key from https://console.anthropic.com/settings/keys
  - **Google** : API key from https://aistudio.google.com/apikey
##  Imports 
The LLMs client is included in the Canvas SDK. Import the necessary components:
    ```python
    from canvas_sdk.clients.llms import (
        LlmOpenai,
        LlmAnthropic,
        LlmGoogle,
        LlmResponse,
        LlmTokens,
        LlmTurn,
    )
    from canvas_sdk.clients.llms.structures.settings import (
        LlmSettingsGpt4,

    # Attempt multiple requests until success or max attempts
    responses = client.attempt_requests(attempts=3)
    # Check the last response
    last_response = responses[-1]
    if last_response.code == HTTPStatus.OK:
        print(f"Success: {last_response.response}")

        print(f"Failed after {len(responses)} attempts")
    ```
##  Analyze an Image 
    ```python
    from canvas_sdk.clients.llms import LlmOpenai
    from canvas_sdk.clients.llms.structures.settings import LlmSettingsGpt4
    from canvas_sdk.clients.llms.constants import FileType
    from canvas_sdk.clients.llms.structures import LlmFileUrl
    client = LlmOpenai(LlmSettingsGpt4(
        api_key="your_api_key",
        model="gpt-4o",
        temperature=0.5,
    ))
    # Set up prompts
    client.set_system_prompt(["You are an image analysis assistant."])
    client.set_user_prompt(["Describe what you see in this image."])
    # Add an image file
    client.add_url_file(LlmFileUrl(
        url="https://example.com/image.jpg",
        type=FileType.IMAGE
    ))
    # Get the analysis
    response = client.request()
    print(response.response)
    ```
##  Analyze a PDF Document 
    ```python
    from canvas_sdk.clients.llms import LlmAnthropic
    from canvas_sdk.clients.llms.structures.settings import LlmSettingsAnthropic
    from canvas_sdk.clients.llms.constants import FileType
    from canvas_sdk.clients.llms.structures import LlmFileUrl
    client = LlmAnthropic(LlmSettingsAnthropic(
        api_key="your_api_key",
        model="claude-sonnet-4-5-20250929",
        temperature=0.5,
        max_tokens=4096,
    ))
    # Set up prompts
    client.set_system_prompt(["You are a document analysis assistant."])
    client.set_user_prompt(["Summarize the key points in this document."])
    # Add a PDF file
    client.add_url_file(LlmFileUrl(
        url="https://example.com/document.pdf",
        type=FileType.PDF
    ))
    # Get the summary
    response = client.request()
    print(response.response)
    ```
##  Upload File Content Directly 
Instead of providing a URL, you can upload file content directly using `FileContent`. This is useful when you have the file data in memory (e.g., from a form upload).
    ```python
    import base64
    from canvas_sdk.clients.llms import LlmOpenai
    from canvas_sdk.clients.llms.structures.settings import LlmSettingsGpt4
    from canvas_sdk.clients.llms.structures import FileContent
    client = LlmOpenai(LlmSettingsGpt4(
        api_key="your_api_key",
        model="gpt-4o",
        temperature=0.5,
    ))
    # Read file content from disk or form upload
    with open("document.pdf", "rb") as f:
        file_bytes = f.read()
    # Create FileContent with base64-encoded data
    file_content = FileContent(
        mime_type="application/pdf",
        content=base64.b64encode(file_bytes),
        size=len(file_bytes),
    )
    # Add to the client's file_content list
    client.file_content.append(file_content)
    # Set up prompts
    client.set_system_prompt(["Analyze the provided document."])
    client.set_user_prompt(["What are the main topics covered in this document?"])
    # Get the analysis
    response = client.request()
    print(response.response)
    ```
**Supported MIME types for direct file content:**
MIME Type Pattern| Description  
---|---  
`image/*`| Images (PNG, JPEG, GIF, etc.)  
`application/pdf`| PDF documents  
`text/*`| Text files (Anthropic only)  
##  Structured JSON Output 
    ```python
    from pydantic import Field
    from canvas_sdk.clients.llms import LlmOpenai
    from canvas_sdk.clients.llms.structures.settings import LlmSettingsGpt4
    from canvas_sdk.clients.llms.structures import BaseModelLlmJson
    # Define your response schema
    class PersonInfo(BaseModelLlmJson):
        name: str = Field(description="The person's full name")
        age: int = Field(description="The person's age in years")
        occupation: str = Field(description="The person's job or profession")
    # Initialize client
    client = LlmOpenai(LlmSettingsGpt4(
        api_key="your_api_key",
        model="gpt-4o",
        temperature=0.3,
    ))
    # Set the schema for structured output
    client.set_schema(PersonInfo)
    # Set up prompts
    client.set_system_prompt(["Extract person information from the text."])
    client.set_user_prompt(["John Smith is a 35-year-old software engineer."])
    # Get structured response
    response = client.request()
    # Response will be valid JSON matching the PersonInfo schema
    print(response.response)  # {"name": "John Smith", "age": 35, "occupation": "software engineer"}
    ```
##  Nested Structured Output 
    ```python
    from pydantic import Field
    from canvas_sdk.clients.llms.structures import BaseModelLlmJson
    # Define nested schemas (all must extend BaseModelLlmJson)
    class Address(BaseModelLlmJson):
        street: str = Field(description="Street address")
        city: str = Field(description="City name")
        country: str = Field(description="Country name")
    class Person(BaseModelLlmJson):
        name: str = Field(description="Full name")
        address: Address = Field(description="Home address")
    # Use with client
    client.set_schema(Person)
    client.set_system_prompt(["Extract person and address information."])
    client.set_user_prompt(["Jane Doe lives at 123 Main St, New York, USA."])
    response = client.request()
    ```

            response = client.attempt_requests(attempts=1)[0]
            return [PlainTextResponse(response.response, status_code=response.code)]
    ```
##  Error Handling 
The LLM clients return `LlmResponse` objects with HTTP status codes indicating success or failure.
    ```python
    from http import HTTPStatus
    response = client.request()
    if response.code == HTTPStatus.OK:
        print(f"Success: {response.response}")
    elif response.code == HTTPStatus.TOO_MANY_REQUESTS:
        print("Rate limited - try again later")
    elif response.code == HTTPStatus.UNAUTHORIZED:
        print("Invalid API key")
    elif response.code == HTTPStatus.BAD_REQUEST:
        print(f"Bad request: {response.response}")
    else:
        print(f"Error {response.code}: {response.response}")
    ```
When using `attempt_requests`, the method will automatically retry on failure:
    ```python
    responses = client.attempt_requests(attempts=3)
    # Check if any attempt succeeded
    successful = [r for r in responses if r.code == HTTPStatus.OK]
    if successful:
        print(f"Success after {len(responses)} attempt(s)")
    else:
        print(f"All {len(responses)} attempts failed")
    ```
##  Provider-Specific Notes 
###  OpenAI 
  - Uses the Responses API (`/v1/responses`)
  - Supports images and PDFs via URL (`add_url_file`) or direct content (`file_content`)
  - System prompts are sent as `instructions`
  - Direct file content uses `input_image` for images and `input_file` for PDFs
###  Anthropic 
  - Uses the Messages API (`/v1/messages`)
  - Supports images, PDFs, and text files via URL or direct content
  - Text files are base64-decoded and sent as plain text
  - Structured output uses tool calling
###  Google Gemini 
  - Uses the Generative Language API
  - Files via URL are downloaded and converted to base64 automatically
  - Supports both URL-based and direct file content
  - Maximum file size limit of 10MB per request (combined)
  - Structured output uses `responseJsonSchema`

# Twilio

Source: https://docs.canvasmedical.com/sdk/clients-twilio/

The Canvas SDK Twilio client provides a simple interface for sending SMS and MMS messages, managing phone numbers, and handling webhooks using the Twilio API.
##  Requirements 
  - **Twilio Account SID** : Found in your [Twilio Console](https://console.twilio.com/)
  - **Twilio API Key and Secret** : Create at [API Keys](https://console.twilio.com/us1/account/keys-credentials/api-keys)
  - **Twilio Phone Number** : Purchase at [Phone Numbers](https://console.twilio.com/us1/develop/phone-numbers/manage/incoming)
##  Imports 
The Twilio client is included in the Canvas SDK. Import the necessary components:
    ```python
    from canvas_sdk.clients.twilio.libraries import SmsClient
    from canvas_sdk.clients.twilio.structures import Settings, SmsMms, RequestFailed
    ```
##  Initialize the Client 
    ```python
    settings = Settings(
        account_sid="your_account_sid",
        key="your_api_key",
        secret="your_api_secret",
    )
    client = SmsClient(settings)
    ```
##  Send a Simple SMS 
    ```python
    from canvas_sdk.clients.twilio.libraries import SmsClient
    from canvas_sdk.clients.twilio.structures import Settings, SmsMms, RequestFailed
    # Initialize the client
    settings = Settings(
        account_sid="ACxxxxxxxxxxxxxxxxx",
        key="SKxxxxxxxxxxxxxxxxx",
        secret="your_api_secret",
    )
    client = SmsClient(settings)
    # First, get your phone number SID
    phones = list(client.account_phone_numbers())
    phone = phones[0]  # Use the first phone number
    print(f"Using phone: {phone.phone_number} (SID: {phone.sid})")
    # Create and send the SMS
    sms = SmsMms(
        number_from=phone.phone_number,
        number_from_sid=phone.sid,
        number_to="+1234567890",
        message="Hello from Canvas SDK!",
        media_url="",
        status_callback_url="",
    )
    try:
        message = client.send_sms_mms(sms)
        print(f"Message sent! SID: {message.sid}, Status: {message.status.value}")
    except RequestFailed as e:
        print(f"Failed to send: {e.message} (HTTP {e.status_code})")
    ```
##  Send an MMS with Image 
    ```python
    # Create an MMS with an image attachment
    mms = SmsMms(
        number_from=phone.phone_number,
        number_from_sid=phone.sid,
        number_to="+1234567890",
        message="Check out this image!",
        media_url="https://example.com/image.jpg",
        status_callback_url="",
    )
    try:
        message = client.send_sms_mms(mms)
        print(f"MMS sent! SID: {message.sid}")
    except RequestFailed as e:
        print(f"Failed to send: {e.message}")
    ```
##  Send SMS with Status Callback 
    ```python
    # Send SMS with a callback URL to track delivery status
    sms = SmsMms(
        number_from=phone.phone_number,
        number_from_sid=phone.sid,
        number_to="+1234567890",
        message="Message with tracking",
        media_url="",
        status_callback_url="https://your-app.com/api/sms-status",
    )
    message = client.send_sms_mms(sms)
    print(f"Message queued with callback. SID: {message.sid}")
    ```
##  Retrieve Message History 
    ```python
    from canvas_sdk.clients.twilio.constants import DateOperation
    # Get all messages (no filters)
    for message in client.retrieve_all_sms("", "", "", DateOperation.ON_EXACTLY):
        print(f"{message.date_sent}: {message.number_from} -> {message.number_to}: {message.body}")
    # Get messages sent to a specific number
    for message in client.retrieve_all_sms("+1234567890", "", "", DateOperation.ON_EXACTLY):
        print(f"To {message.number_to}: {message.body}")
    # Get messages from a specific date onwards
    for message in client.retrieve_all_sms("", "", "2024-01-01", DateOperation.ON_AND_AFTER):
        print(f"{message.date_sent}: {message.body}")
    ```
##  Handle Inbound Messages (Webhook) 
When Twilio receives an SMS to your number, it can call your webhook. Parse the callback data:
    ```python
    from canvas_sdk.clients.twilio.structures import StatusInbound, TwiMlMessage
    def handle_inbound_sms(raw_body: str) -> str:
        """Process incoming SMS and return TwiML response."""
        # Parse the incoming message
        inbound = StatusInbound.callback_inbound(raw_body)
        print(f"Received from {inbound.number_from}: {inbound.body}")
        # Create a reply using TwiML
        if "hello" in inbound.body.lower():
            reply = TwiMlMessage.instance("Hello! Nice to hear from you!")
        else:
            reply = TwiMlMessage.instance("Thanks for your message!")
        return reply.to_xml()
    ```
##  Reply with MMS (TwiML) 
    ```python
    from canvas_sdk.clients.twilio.structures import TwiMlMessage
    # Create a TwiML response with text and image
    reply = TwiMlMessage.instance_with_media(
        message_text="Here's a picture for you!",
        media_url="https://example.com/image.jpg"
    )
    xml_response = reply.to_xml()
    # Returns TwiML like:
    # <?xml version="1.0" encoding="UTF-8"?>
    # <Response><Message><Body>Here's a picture for you!</Body><Media>https://example.com/image.jpg</Media></Message></Response>
    ```

# Clients

Source: https://docs.canvasmedical.com/sdk/clients/

The clients module provides pre-built integrations with popular third-party services, letting your plugins send emails, SMS messages, interact with AI models, process documents, and manage cloud storage. Each client handles authentication, request formatting, and response parsing so you can focus on your plugin's logic.
All clients follow a consistent pattern: configure credentials via [plugin secrets](/sdk/secrets/), instantiate a client, and call methods. Error handling is standardized with a `RequestFailed` exception across most clients.
> **Warning:** When using third-party clients with your own API keys, you are responsible for all privacy, security, and regulatory compliance associated with those services. For certain providers such as OpenAI and Anthropic, you may contact Canvas to inquire about access through our compliant accounts.

# Command Metadata Create form

Source: https://docs.canvasmedical.com/sdk/command-metadata-create-form-effect/

##  Overview 
The `CommandMetadataCreateFormEffect` allows developers to dynamically display additional fields with a command in a note. The values entered in these fields are stored as [command metadata](/sdk/data-command/#commandmetadata) against the target `command_uuid`.
The effect is returned from a handler that responds to the `COMMAND__FORM__GET_ADDITIONAL_FIELDS` event.
    ```python
    from canvas_sdk.effects.command_metadata import (
        CommandMetadataCreateFormEffect,
        FormField,
        InputType,
    )
    CommandMetadataCreateFormEffect(
        command_uuid="command-uuid",
        form_fields=[
            FormField(
                key="reason",
                label="Reason",
                type=InputType.SELECT,
                options=["Routine", "Follow-up", "Other"],
            ),
        ],
    )
    ```
##  Structure 
###  **FormField**
A FormField consists of the following properties:
####  Attributes 
Attribute| Type| Description  
---|---|---  
`key`| `str`| unique identifier of the field - command metadata key  
`label`| `str`| the label that will be displayed on the field  
`type`| `InputType`| the type of the input - TEXT, SELECT, DATE.  
`required`| `bool`| if the input is required.  
`editable`| `bool`| if the input can be editabled.  
`options`| `list[str]`| possible options for when the input type is set to "SELECT"  
`value`| `str`| default value used only when no CommandMetadata row exists for this key. If the user has previously saved a value (including a cleared/empty value) the stored row wins and this field is ignored.  
###  **CommandMetadataCreateFormEffect**
A CommandMetadataCreateFormEffect consists of the following properties:
####  Attributes 
Attribute| Type| Description  
---|---|---  
`command_uuid`| `str`| the UUID of the command these fields should be rendered on.  
`form_fields`| `list[FormField]`| list of fields.  
##  Validation 
The effect validates inputs before it is applied:
  - `command_uuid` is required.
  - `options` may only be set on fields whose `type` is `InputType.SELECT`; providing `options` on a `TEXT` or `DATE` field raises a validation error.
  - Every `key` must be unique across `form_fields`. Duplicates raise a validation error per duplicated key.
##  Example Usage 
The following handler declares two extra fields on every plan command when the platform requests additional fields for it:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.command_metadata import (
        CommandMetadataCreateFormEffect,
        FormField,
        InputType,
    )
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class PlanCommandAdditionalFields(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.COMMAND__FORM__GET_ADDITIONAL_FIELDS)
        def compute(self) -> list[Effect]:
            # Only respond for plan commands.
            if self.event.context.get("schema_key") != "plan":
                return []
            form = CommandMetadataCreateFormEffect(
                command_uuid=self.event.target.id,
                form_fields=[
                    FormField(
                        key="priority",
                        label="Priority",
                        type=InputType.SELECT,
                        options=["low", "medium", "high"],
                    ),
                    FormField(
                        key="follow_up_date",
                        label="Follow-up date",
                        type=InputType.DATE,
                        editable=True,
                    ),
                ],
            )
            return [form.apply()]
    ```
Once the user fills out these fields, their values are persisted as command metadata and can be read back through the SDK [command metadata](/sdk/data-command/#commandmetadata) table.
##  Rendering on the printed note 
The same `COMMAND__FORM__GET_ADDITIONAL_FIELDS` event fires when a command is rendered for printing (single-command print URL or full note printout). The platform uses the response to label and order the fields shown beneath each command in the printed output.
Two things differ from the chart-form render path:
  - **Values come from stored command metadata, not from`FormField.value`.** The platform pairs each field declared in your effect with the matching `CommandMetadata` row by `key`. Whatever value is on `FormField` is ignored during print rendering. You do not need to populate `value` for print.
  - **Fields with no stored value or a blank value are skipped.** Only fields the user actually filled in will appear in the printout.
  - **Fields you do not declare are hidden.** A `CommandMetadata` row whose `key` is not in your response will not print, even if it exists in the database. This matches the chart UI: removing or renaming a key in your effect makes the prior data invisible.
###  Branching on `purpose`
The event context carries a `purpose` key indicating which call site triggered the request:
Value| When  
---|---  
`"form"`| Chart UI is rendering the command's edit form (default).  
`"print"`| Single-command printout or note printout is being generated.  
Read it from the handler context to vary your response — for example, to omit internal fields from print, or shorten labels for a denser layout.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.command_metadata import (
        CommandMetadataCreateFormEffect,
        FormField,
        InputType,

    from canvas_sdk.handlers import BaseHandler
    class PlanCommandAdditionalFields(BaseHandler):

        def compute(self) -> list[Effect]:
            if self.event.context.get("schema_key") != "plan":

            is_print = self.event.context.get("purpose") == "print"
            fields = [
                FormField(

                    label="Priority",
                    type=InputType.SELECT,
                    options=["low", "medium", "high"],

                FormField(
                    key="follow_up_date",
                    label="Follow-up date",
                    type=InputType.DATE,
                ),
            ]
            if not is_print:
                # Internal-only: visible on the form, hidden from printouts.
                fields.append(
                    FormField(
                        key="reviewer_notes",
                        label="Reviewer notes",
                        type=InputType.TEXT,
                    )
                )
            return [
                CommandMetadataCreateFormEffect(
                    command_uuid=self.event.target.id,
                    form_fields=fields,
                ).apply()
            ]
    ```
###  Tips for the print path 
  - **Use clear, human-readable`label` values.** Whatever you put on `FormField.label` is what the printed output shows. The platform does not derive a label from the `key`.
  - **Use the same`key` you used when persisting metadata.** The print path joins on `key`; mismatches mean nothing renders for that field.
  - **`type`, `options`, and `required` are ignored at print time.** Only `key` and `label` shape the printout.
  - **Need to retire a field?** Removing it from the print response hides it for all future prints — including for committed notes. If you need the historical value to keep showing on signed records, keep the field declared (or declare it only when `purpose == "print"`).

# Custom Command

Source: https://docs.canvasmedical.com/sdk/commands-custom-command/

##  Introduction 
The `CustomCommand` class allows plugins to create custom commands with HTML-rendered content that can be inserted into patient charts. Custom commands are designed for displaying read-only content and do not support user input or interactive forms.
**Important** : Custom commands must be configured in the plugin's `CANVAS_MANIFEST.json` file under the `commands` array before they can be used.
##  Parameters 
Name| Type| Required| Description  
---|---|---|---  
`note_uuid`|  _string_| `true`| The externally exposable id of the note in which to insert the command.  
`command_uuid`|  _string_| `true`| The externally exposable id of the command which is being referenced.  
`schema_key`|  _string_| `true`| Identifier for data binding. Must match the `schema_key` in your manifest configuration and must be unique across every plugin installed on the instance.  
`content`|  _string_| `true`| HTML content for display in the chart.  
`print_content`|  _string_| `false`| HTML content for print version (recommended for optimal print output).  
##  Manifest Configuration 
Custom commands must be declared in your `CANVAS_MANIFEST.json`:
    ```json
    {
      "components": {
        "commands": [
          {
            "name": "RiskAssessment",
            "label": "Risk Assessment",
            "schema_key": "riskAssessment",
            "section": "assessment"
          }
        ]
      }
    }
    ```
###  Manifest Fields 
  - **name** : Unique name for the command
  - **label** : User-friendly label displayed in Canvas UI
  - **schema_key** : Identifier for the command. Must be unique across every plugin installed on the Canvas instance — if another installed plugin already declares the same `schema_key`, installation will be rejected. CustomCommand instances must use this value.
  - **section** : Chart section where command appears: `subjective`, `objective`, `assessment`, `plan`, `procedures`, `history`, or `internal`
**Note** : `schema_key` values must be unique across **all plugins installed on the instance** , not just within a single plugin. If you install a plugin whose manifest declares a `schema_key` already owned by another installed plugin, the installation fails with a clear validation error instead of silently overwriting the existing command. Choose a distinctive `schema_key` — for example, prefixing it with your plugin's name — to avoid collisions.
##  Basic Usage 
###  Step 1: Create HTML Templates 
Create a template file for your command content (e.g., `templates/risk_assessment.html`):
    ```html
    <!DOCTYPE html>
    <html>
    <head>
        <style>
            .risk-assessment {
                font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif;
                padding: 16px;
            }
            .risk-header {
                font-size: 18px;
                font-weight: 600;
                margin-bottom: 16px;
            }
            .risk-item {
                padding: 8px;
                margin-bottom: 8px;
                background: #f7fafc;
                border-radius: 4px;
            }
            .risk-level {
                font-weight: 600;
                color: #c53030;
            }
        </style>
    </head>
    <body>
        <div class="risk-assessment">
            <div class="risk-header">Risk Assessment</div>
            <div class="risk-item">
                <span class="risk-level">Cardiovascular Risk: High</span>
                <p>Hypertension, family history of heart disease</p>
            </div>
            <div class="risk-item">
                <span class="risk-level">Falls Risk: Moderate</span>
                <p>Age over 65, history of dizziness</p>
            </div>
        </div>
    </body>
    </html>
    ```
Create a simpler print version (e.g., `templates/risk_assessment_print.html`):
    ```html
    <!DOCTYPE html>
    <html>
    <head>
        <style>
            .risk-assessment-print {
                font-family: Arial, sans-serif;
                font-size: 11px;
                .section {
                    margin-bottom: 8px;
                }
                .label {
                    font-weight: bold;
                }
            }
        </style>
    </head>
    <body class="risk-assessment-print">
        <h3>Risk Assessment</h3>
        <div class="section">
            <span class="label">Cardiovascular Risk:</span> High - Hypertension, family history
        </div>
        <div class="section">
            <span class="label">Falls Risk:</span> Moderate - Age over 65, history of dizziness
        </div>
    </body>
    </html>
    ```
###  Step 2: Use Templates in Your Command 
    ```python
    from canvas_sdk.commands.commands.custom_command import CustomCommand
    from canvas_sdk.templates import render_to_string
    import uuid
    command = CustomCommand(
        schema_key="riskAssessment",
        content=render_to_string("templates/risk_assessment.html"),
        print_content=render_to_string("templates/risk_assessment_print.html")
    )
    command.command_uuid = str(uuid.uuid4())
    command.note_uuid = "rk786p"
    effect = command.originate()
    ```
###  Extended CustomCommand Class (For Reusability) 
Create a subclass with a predefined `schema_key`:
    ```python
    from canvas_sdk.commands.commands.custom_command import CustomCommand
    from canvas_sdk.templates import render_to_string
    import uuid
    class RiskAssessmentCommand(CustomCommand):
        """Custom command for risk assessment."""
        class Meta:
            schema_key = "riskAssessment"
    # Usage
    command = RiskAssessmentCommand(
        content=render_to_string("templates/risk_assessment.html"),
        print_content=render_to_string("templates/risk_assessment_print.html")
    )
    command.command_uuid = str(uuid.uuid4())
    command.note_uuid = "rk786p"
    effect = command.originate()
    ```
##  Methods 
###  originate() 
Returns an Effect that originates a new command in the note body.
**Example:**
    ```python
    from canvas_sdk.commands.commands.custom_command import CustomCommand
    from canvas_sdk.templates import render_to_string
    import uuid
    command = CustomCommand(
        schema_key="riskAssessment",
        content=render_to_string("templates/risk_assessment.html"),
        print_content=render_to_string("templates/risk_assessment_print.html")
    )
    command.command_uuid = str(uuid.uuid4())
    command.note_uuid = "rk786p"
    effect = command.originate()
    ```
##  Content vs Print Content 
Custom commands support two versions of content:
###  Display Content (content) 
  - Rendered in the Canvas UI when viewing the chart
  - Can include rich styling and complex layouts
###  Print Content (print_content) 
  - Rendered when printing the chart or generating PDFs
  - Should be simpler and more compact
**Best Practice** : Always provide both versions for the best user experience.
##  Limitations 
  - Custom commands are read-only and cannot capture user input
  - Interactive elements (forms, buttons, input fields) are not supported
  - Commands must be configured in the manifest before use
  - The `schema_key` must be unique across every plugin installed on the Canvas instance. Installing a plugin whose `schema_key` is already owned by another installed plugin will fail with a validation error.

# Commands

Source: https://docs.canvasmedical.com/sdk/commands/

The commands module lets you create and update commands within a specific note in Canvas. Commands are the building blocks of many end-user workflows in Canvas, including nearly all clinical workflows for documentation, like HPIs and questionnaires, as well as orders like prescriptions, labs, and referrals. Each Command class can be instantiated in your plugin and used to build a new command instance within a specific note or update an existing instance. The commands are then displayed in real time within the end user's workflow.
Common objectives that can be met by using Command classes include dynamic note templates, clinical decision support, order set composition, care gap closure, and care coordination automation.
Commands are written from an event handler by default. To let something outside Canvas write them — a patient-facing form, a device, an internal tool — expose them over HTTP with [`CommandAPI`](/sdk/handlers-simple-api-commands/), which reads a request body onto any command on this page, validates it, and emits the effects. The [Writing Commands Over HTTP](/guides/writing-commands-over-http/) guide walks through building one.
> **Info:** New to command fields? Fields that are autocompletes, dropdowns, or enums in the Canvas UI take a raw code, id, or enum value in the SDK — you have to look the value up first. See [Populating Command Fields](/guides/populating-command-fields/) for where each value comes from.
##  Common Attributes 
###  Parameters 
All commands share the following init kwarg parameters:
Name| Type| Required| Description  
---|---|---|---  
`note_uuid`|  _string_| `true` if creating a new command| The id of the [Note](/sdk/data-note/#note) in which to insert the command.  
`command_uuid`|  _string_| `true` if updating an existing command| The id of the [Command](/sdk/data-command/#command). On `originate` you can pass your own value to set it the first time; when updating, it references an existing command.  
All parameters can be set upon initialization, and also updated on the class instance.
Field values are read leniently, so a value does not have to arrive already in the field's own type: a number can be given as `"3"`, a date as `"2026-08-04"`, and an enum as its value (`"mild"`) rather than the member. This matters most when the values come from somewhere that only has strings, such as a JSON request body.
###  Methods 
**Not every command supports every method.** `originate` is the only one they all have; `edit`, `delete`, `commit`, `enter_in_error`, `review`, `send`, `delegate` and `sign` each depend on the command. The [command type table](/sdk/effects/#commands) lists the actions each command accepts — check it before relying on one. `upsert_metadata` works on any command, and `set_custom_html` belongs to [custom commands](/sdk/commands-custom-command/) alone.
To call these over HTTP rather than from a handler, see [`CommandAPI`](/sdk/handlers-simple-api-commands/#methods).
####  originate 
Returns an Effect that originates a new command in the note body.
**Parameters:**
Name| Type| Required| Default| Description  
---|---|---|---|---  
`commit`| `bool`| No| `False`| When `True`, the command is automatically committed after origination. This is a simpler alternative to returning separate `originate()` and `commit()` effects. **Note:** This only applies to command types that support the COMMIT action. Commands that do not support committing (Reason For Visit, Prescribe, Refill, Adjust Prescription, Refer, and Order commands) will ignore this parameter. See the [command type table](/sdk/effects/#commands) for which commands support COMMIT.  
`line_number`| `int`| No| `-1`| The line number in the note where the command should be inserted. By default the command will insert at the bottom of the note.  
**See also:** For efficiently inserting multiple commands at once, see [Batch Originate Commands](/sdk/effect-batch-originate/).
**Examples** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        new_plan = PlanCommand(note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47', narrative='new')
        new_plan.narrative = 'newer'
        return [new_plan.originate()]
    ```
To originate and commit in a single effect:
    ```python
    from canvas_sdk.commands import DiagnoseCommand
    def compute():
        diagnose_command = DiagnoseCommand(
            note_uuid='550e8400-e29b-41d4-a716-446655440000',
            icd10_code='E11.9'
        )
        return [diagnose_command.originate(commit=True)]
    ```
####  edit 
Returns an Effect that edits an existing command with the values set on the command class instance.
**Behavior and Considerations:**
  - **Partial Edits:** If you update only some fields of the command, any fields not explicitly modified will retain their existing values.
  - **No Changes:** Calling `edit()` without making any changes will result in a no-op; the command remains unchanged.
  - **Invalid Values:** If you attempt to set an invalid value, you should receive a validation error.
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d', narrative='something new')
        return [existing_plan.edit()]
    ```
####  delete 
Returns an Effect that deletes an existing, non-committed command from the note body.
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.delete()]
    ```
####  commit 
Returns an Effect that commits an existing, non-committed command to the note body.
To block a command from committing and surface a message to the user — for example, enforcing your own business rules before a command is entered — return a [Command Validation effect](/sdk/effect-command-validation/) from a handler on the command's validation event.
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.commit()]
    ```
####  review 
Returns an Effect that sets a command in review.
**Limited availability** The `review()` method can only be called on Prescribe commands objects. Other command types do not support this operation.
**Example** :
    ```python
    from canvas_sdk.commands import PrescribeCommand
    def compute():
        existing_prescribe = PrescribeCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_prescribe.review()]
    ```
####  send 
Returns an Effect that sends a signed command.
**Limited availability** The `send()` method can only be called on LabOrder, Prescribe, Refill and AdjustPrescription command objects. Other command types do not support this operation. The three prescribing commands share one set of electronic prescribing validations.
**Parameters:**
Name| Type| Required| Default| Description  
---|---|---|---|---  
`practice_location_override`| `str \| UUID`| No| `None`| Prescribe only. The `id` of a [PracticeLocation](/sdk/data-practicelocation/#practicelocation) whose address is used as the prescriber address on the outgoing prescription, overriding the prescriber's primary location. See Prescribe for behavior and limitations.  
**Example** :
    ```python
    from canvas_sdk.commands import PrescribeCommand
    def compute():
        existing_prescribe = PrescribeCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_prescribe.send()]
    ```
To send the prescription using a specific practice location's address (see Prescribe):
    ```python
    from canvas_sdk.commands import PrescribeCommand
    def compute():
        existing_prescribe = PrescribeCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_prescribe.send(practice_location_override='a1b2c3d4-e5f6-7890-abcd-ef1234567890')]
    ```
####  enter_in_error 
Returns an effect that enter-in-errors an existing, committed command in the note body.
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.enter_in_error()]
    ```
####  delegate 
Returns an Effect that delegates an existing, staged command by creating a task.
**Limited availability** The `delegate()` method can only be called on ImagingOrder and Refer command objects. Other command types do not support this operation.
**Example** :
    ```python
    from canvas_sdk.commands import ReferCommand
    def compute():
        existing_refer = ReferCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_refer.delegate()]
    ```
####  sign 
Returns an Effect that signs an existing, staged command, transitioning it to a committed state.
**Limited availability** The `sign()` method can only be called on ImagingOrder and Refer command objects. Other command types do not support this operation.
**Example** :
    ```python
    from canvas_sdk.commands import ImagingOrderCommand
    def compute():
        existing_imaging_order = ImagingOrderCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_imaging_order.sign()]
    ```
####  upsert_metadata 
Returns a [CommandMetadata effect](/sdk/effect-command-metadata/) that creates or updates a metadata key-value pair on a command. If metadata with the given key already exists on the command, its value will be updated. Otherwise, a new metadata record will be created.
The `command_uuid` field must be set on the command object before calling `upsert_metadata`.
To make this metadata **visible and editable as fields on the command in the note** — rather than only stored behind the scenes — use the [Command Metadata Create Form effect](/sdk/command-metadata-create-form-effect/), which renders additional fields on the command whose values are saved as command metadata.
Parameter| Type| Description  
---|---|---  
`key`|  _string_|  The metadata key (max 256 characters).  
`value`|  _string_|  The metadata value.  
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.upsert_metadata(key="priority", value="high")]
    ```
####  set_custom_html 
Returns an effect that sets or clears custom HTML content on a command. The HTML is stored on the command and rendered alongside it in the note.
The `command_uuid` field must be set on the command object before calling `set_custom_html`. The command must be in a staged (not committed) state—calling this method on a committed command will raise a validation error.
Parameter| Type| Description  
---|---|---  
`custom_html`|  _string_ or _None_|  The HTML content to set on the command, or `None` to clear it.  
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.set_custom_html("<div class='highlight'>Important note</div>")]
    ```
To clear existing custom HTML from a command:
    ```python
    from canvas_sdk.commands import PlanCommand
    def compute():
        existing_plan = PlanCommand(command_uuid='2b9d1f0a-4c3e-4b5a-9d8c-7e6f5a4b3c2d')
        return [existing_plan.set_custom_html(None)]
    ```
##  Originating and Committing Together 
The simplest way to originate and commit a command in a single plugin action is to pass `commit=True` to the `originate()` method:
    ```python
    from canvas_sdk.commands import DiagnoseCommand
    def compute():
        diagnose_command = DiagnoseCommand(
            note_uuid='550e8400-e29b-41d4-a716-446655440000',
            icd10_code='E11.9'
        )
        return [diagnose_command.originate(commit=True)]
    ```
This handles the origination and commit in a single effect, without needing to manage a `command_uuid` yourself.
###  Chaining Methods with a User-set UUID 
If you need more control over the process — for example, to edit a command between origination and commit — you can chain separate effects by setting the `command_uuid` manually. This is also required for questionnaire-based commands, where `originate()` creates the command but does not add the answers — you must chain an `edit()` to populate the responses (see Usage Example). This chaining is necessary because the `originate` method executes asynchronously, so there is no way to get the `command_uuid` back from the originate action and use it for subsequent actions in the same operation.
    ```python
    from uuid import uuid4
    from canvas_sdk.commands import DiagnoseCommand
    def compute():
        note_uuid = '550e8400-e29b-41d4-a716-446655440000'
        diagnose_command = DiagnoseCommand(
            note_uuid=note_uuid,
            icd10_code='E11.9'
        )
        # To chain command effects, you must know what the command's id
        # is. To accomplish that, we set the id ourselves rather than
        # allow the database to assign one.
        diagnose_command.command_uuid = str(uuid4())
        # Now we can both originate and commit in a single operation
        return [diagnose_command.originate(), diagnose_command.commit()]
    ```
This pattern ensures that both the originate and commit operations use the same `command_uuid`, allowing them to be chained together reliably in a single plugin execution.
Command-specific details for each command class can be found below.
##  Command Actions 
All commands support user-triggered actions through the Canvas UI. These actions appear as buttons or menu items that users can click to perform operations on a command.
Commands have two types of actions:
  - **Generic actions** — available on all commands (listed below).
  - **Command-specific actions** — vary by command type and are documented in each command's section below.
Action| Description  
---|---  
`print`| Generates a printable version of the command for documentation or external sharing.  
`audit_history`| Displays the complete audit trail for the command, showing all modifications, state changes, and user interactions over time.  
`carry_forward`| Populates the command with the last known data for this command type and patient, letting users quickly recreate a similar command from a previous entry.  
> **Info:** The send action is the only command action available through the SDK, and only LabOrder, Prescribe, Refill and Adjust Prescription commands support it.
###  Customizing Action Availability 
You can programmatically control which actions appear on a command — and in what order — by responding to that command's `AVAILABLE_ACTIONS` event. Common uses:
  - **Hide actions** based on user permissions, role, or command state.
  - **Reorder actions** to prioritize commonly used operations.
  - **Conditionally show actions** depending on workflow or business logic.
**How it works:**
  1. When Canvas renders a command, it fires that command's `<COMMAND>_COMMAND__AVAILABLE_ACTIONS` event (e.g. `PLAN_COMMAND__AVAILABLE_ACTIONS`).
  2. Your handler receives the default action list in `self.context["actions"]` and the acting user in `self.context["user"]`.
  3. Return a single `COMMAND_AVAILABLE_ACTIONS_RESULTS` effect whose payload is the action list you want rendered. The returned list **replaces** the default set, so include every action the user should see — returning the original list unchanged is a no-op.
**Example** — hide the `print` action for a specific user:
    ```python
    import json
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.v1.data import Staff
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__AVAILABLE_ACTIONS)
        def compute(self) -> list[Effect]:
            actions = self.context["actions"]
            user_id = self.context["user"]["staff"]
            try:
                staff = Staff.objects.get(id=user_id)
                # Hide the print action for this user; everyone else keeps the full set
                if staff.first_name == "Larry":
                    filtered_actions = [a for a in actions if a["name"] != "print"]
                else:
                    filtered_actions = actions
            except Staff.DoesNotExist:
                filtered_actions = actions
            return [
                Effect(
                    type=EffectType.COMMAND_AVAILABLE_ACTIONS_RESULTS,
                    payload=json.dumps(filtered_actions),
                )
            ]
    ```
##  Command Validation 
Beyond the built-in validation each command performs on its own fields, you can add your **own** validation rules to a command and surface error messages to the user directly in the Canvas UI. A handler responds to a command's validation event (for example, `PLAN_COMMAND__POST_VALIDATION`) and returns a [Command Validation effect](/sdk/effect-command-validation/) containing one or more error messages. This is useful for enforcing organization-specific business rules — such as requiring a field, restricting certain combinations, or blocking a command until an external condition is met — before the command can be committed.
See the [Command Validation effect](/sdk/effect-command-validation/) documentation for the full API and examples.
##  Commands 
The sections below document each command class. See Common Attributes for the parameters and methods shared by all commands.
###  Custom Commands 
For creating custom commands with HTML-rendered content that can be inserted into patient charts, see the [CustomCommand](/sdk/commands-custom-command/) documentation.
Custom commands are different from standard commands:
  - They allow you to display read-only HTML content in the patient chart
  - They must be configured in your plugin's manifest before use
  - They support both display and print versions of content
  - They are designed for displaying formatted data, not for capturing user input

        pharmacy="pharmacy_ncpdp_id",
        prescriber_id="a7c2e9d1-3b4f-4a6c-8e0d-5f1a2b3c4d5e",
        supervising_provider_id="c3d4e5f6-7a8b-4c9d-0e1f-2a3b4c5d6e7f",
        note_to_pharmacist="Please verify patient's insurance before processing."
    )

`severity`|  _Severity enum_| `false`| The severity of the allergic reaction. Must be one of `AllergyCommand.Severity`.  
`narrative`|  _string_| `false`| A narrative or free-text description of the allergy (max length: 512 characters).  
`approximate_date`|  _datetime_| `false`| The approximate date the allergy was identified.  
**Enums and Types** :
**`Allergen`**
Attribute| Type| Description  
---|---|---  
`concept_id`|  _integer_|  The identifier for the allergen concept.  
`concept_type`|  _AllergenType enum_| The type of allergen. See `AllergenType` values below.  
AllergenType| Value| Description  
---|---|---  
`ALLERGEN_GROUP`| `1`| Represents a group of allergens.  
`MEDICATION`| `2`| Represents a medication allergen.  
`INGREDIENT`| `6`| Represents an ingredient allergen.

---|---|---  
`MILD`| `"mild"`| Indicates a mild reaction.  
`MODERATE`| `"moderate"`| Indicates a moderate reaction.  
`SEVERE`| `"severe"`| Indicates a severe reaction.  
**Example** :
    ```python
    from canvas_sdk.commands.commands.allergy import AllergyCommand, AllergenType, Allergen
    from datetime import date
    allergy = AllergyCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        allergy=Allergen(concept_id=12345, concept_type=AllergenType.MEDICATION),
        severity=AllergyCommand.Severity.SEVERE,
        narrative="Severe rash and difficulty breathing after penicillin.",
        approximate_date=date(2023, 6, 15)
    )
    ```
* * *
###  Assess 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`condition_id`|  _string_| `true`| The id of the [Condition](/sdk/data-condition/#condition) being assessed. Must be a condition already recorded on that patient's chart.  
`background`|  _string_| `false`| Background information about the diagnosis.  
`status`|  _Status enum_| `false`| The current status of the diagnosis. Must be one of `AssessCommand.Status`.  
`narrative`|  _string_| `false`| The narrative for the current assessment (max 2048 characters; values exceeding the limit raise a validation error instead of being truncated).  
`Status`| Value| Description  
---|---|---  
`IMPROVED`| `"improved"`| The condition has improved.  
`STABLE`| `"stable"`| The condition is stable.  
`DETERIORATED`| `"deteriorated"`| The condition has deteriorated.  
**Example** :
    ```python
    from canvas_sdk.commands import AssessCommand
    assess = AssessCommand(
        note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47',
        condition_id='a1c2e3d4-5b6f-4a7c-8e9d-0f1a2b3c4d5e',
        background='started in 2012',
        status=AssessCommand.Status.STABLE,
        narrative='experiencing more pain lately'
    )
    ```
**Validation** :
`condition_id` must belong to the same patient as the note or command it is written to: the patient comes from `note_uuid` when you `originate` the command, and from the existing command when you `edit` one. A condition on another patient's chart — or an id that matches no condition at all — fails validation, and the command is neither created nor updated. This check is deferred when the target note (on `originate`) or command (on `edit`) is not yet persisted — for example, when a plugin creates the note and originates `AssessCommand`s against that same `note_uuid` in a single handler response. In that case the note's or command's patient cannot be resolved yet, so `condition_id` passes this validation. The patient-ownership check then runs later, once the command is applied and the note exists.
The check needs that note or command to exist, so it is skipped when you create the note and originate the command in the same batch of effects. Nothing is rejected in that case, since there is not yet a chart to compare the condition against.
* * *
###  ChangeMedication 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`medication_id`|  _string_| `true`| The id of the [Medication](/sdk/data-medication/#medication) being changed. Must be an active medication on that patient's chart.  
`sig`|  _string_| `false`| Administration details of the medication.  
**Example** :
    ```python
    from canvas_sdk.commands.commands.change_medication import ChangeMedicationCommand
    change_medication = ChangeMedicationCommand(
        note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47',
        medication_id='f0a1b2c3-d4e5-4f6a-8b9c-0d1e2f3a4b5c',
        sig='two pills taken orally'
    )
    ```
**Validation** :
`medication_id` must belong to the same patient as the note or command it is written to: the patient comes from `note_uuid` when you `originate` the command, and from the existing command when you `edit` one. The medication must also be active. A medication on another patient's chart, an id that matches no medication, or an inactive medication fails validation, and the command is neither created nor updated. This check is deferred when the target note (on `originate`) or command (on `edit`) is not yet persisted — for example, when a plugin creates the note and originates the command in the same batch of handler effects. In that case the command's patient cannot be resolved yet, so `medication_id` passes this validation; the check then runs once the command is applied.
A malformed `medication_id` fails at command construction, before any patient lookup, while a well-formed UUID passed as a string is accepted.
* * *
###  ChartSectionReview 
Records that a section of the patient's chart was reviewed during a visit. Originating the command snapshots the patient's active records in that section onto the note, along with the rendered text of those records as they read at the time of review — the same thing that happens when a user clicks **Review** on a chart section in the Canvas UI. Use it to attest to a review your plugin has already performed, such as reconciling medications from an external source.
The command is always committed on origination, so there is no staged state to fill in and no need to pass `commit=True`.
Read the resulting snapshot back with the [ChartSectionReview](/sdk/data-chart-section-review/#chartsectionreview) data model.
> **Info:** This command supports `originate()` only since it is a read only command.
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`section`|  _ChartSectionReviewCommand.Sections enum_| `true`| The chart section being reviewed. Required when instantiating the command. Must be one of `ChartSectionReviewCommand.Sections`.  
**Example** :
    ```python
    from canvas_sdk.commands import ChartSectionReviewCommand
    def compute():
        medication_review = ChartSectionReviewCommand(
            note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
            section=ChartSectionReviewCommand.Sections.MEDICATIONS,
        )
        return [medication_review.originate()]
    ```
####  ChartSectionReviewCommand.Sections 
Member| Value| Chart section  
---|---|---  
`CONDITIONS`| `conditions`| Conditions  
`SURGICAL_HISTORY`| `surgical_history`| Surgical History  
`MEDICATIONS`| `medications`| Medications  
`FAMILY_HISTORY`| `family_histories`| Family Histories  
`ALLERGIES`| `allergies`| Allergies  
`IMMUNIZATIONS`| `immunizations`| Immunizations  
> **Warning:** The member name for family history differs between the command and the data model: the command uses `ChartSectionReviewCommand.Sections.FAMILY_HISTORY`, while the data model uses `ChartSectionReviewSection.FAMILY_HISTORIES`. Both carry the same value, `family_histories`.
* * *
###  CloseGoal 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`goal_id`|  _int_| `true`| The `dbid` of the [Goal](/sdk/data-goal/#goal) being closed. Must be a goal on that patient's chart.  
`achievement_status`|  _AchievementStatus enum_| `false`| The final achievement status of the goal. Must be one of `GoalCommand.AchievementStatus`.  
`progress`|  _string_| `false`| A narrative about the patient's progress toward the goal.  
**Example** :
    ```python
    from canvas_sdk.commands import CloseGoalCommand, GoalCommand
    close_goal = CloseGoalCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        goal_id=12345,

**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`icd10_code`|  _string_| `true`| ICD-10 code of the condition being diagnosed. Search with the [ICD-10 condition endpoint](/sdk/utils/#get-icdcondition--icd-10-conditions).

        icd10_code='M54.50',
        background='lifted heavy box',
        approximate_date_of_onset=datetime(2012, 1, 1),
        today_assessment='unable to sleep lately'
    )
    ```

###  FamilyHistory 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`family_history`|  _string_ or _Coding_| `true`| A description of the family history being documented. Search with the [family-history endpoint](/sdk/utils/#get-snomedfamily-history--family-history-conditions).  
`relative`|  _string_| `false`| A description of the relative (e.g., mother, uncle). Search with the [family-relation endpoint](/sdk/utils/#get-snomedfamily-relation--family-relationships).  
`note`|  _string_| `false`| Additional notes or context about the family history (max length: 512 characters).  
**Coding Support** :
The `family_history` parameter accepts either:
  - **String** : Searches for matching family history conditions and selects the first result.
  - **Coding object** : Allows structured or unstructured coding
    - Supported systems: `SNOMED`, `UNSTRUCTURED`
    - Required fields: `system`, `code`
    - Optional field: `display`
The `relative` parameter also searches and selects the first result when a string is provided. Use specific terms (e.g., `"Paternal Grandfather"`, `"Maternal Grandfather"`) to avoid ambiguous matches.
**Example** :
    ```python
    from canvas_sdk.commands import FamilyHistoryCommand
    from canvas_sdk.commands.constants import CodeSystems, Coding
    # Using a string (searches and takes the first result — may be ambiguous)
    family_history = FamilyHistoryCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        family_history="Diabetes Type 2",

        ),
        relative="Mother",
        note="Diagnosed at age 45"
    )
    # Using unstructured (free text)

###  Immunize 
Records a vaccine **administered** during the visit, including the lot it came from.
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`vaccine_id`|  _UUID_| `true`| The `id` of a [Vaccine](/sdk/data-vaccine/#vaccine) in this instance's catalog. Must be active.  
`lot_id`|  _UUID_| `false`*| The `id` of a [VaccineLot](/sdk/data-vaccine/#vaccinelot) with doses on hand.  
`lot_number`|  _string_| `false`*| A lot number this instance does not stock, recorded as free text (max 20 characters).  
`manufacturer`|  _string_| `false`| The vaccine's manufacturer (max 100 characters).  
`expiration_date`|  _date_| `false`| The lot's expiration date.  
`sig`|  _string_| `false`| Directions, as free text - for example `"0.5 mL IM, left deltoid"` (max 75 characters).  
`consent_given`|  _boolean_| `true`| Whether the patient consented after reviewing the Vaccine Information Statement. Must be `true` to commit.  
`given_by_id`|  _string_| `true`| The `id` of the [Staff](/sdk/data-staff/#staff) member who administered the vaccine. Must be active.  
*`lot_id` and `lot_number` are mutually exclusive; supplying both raises an error. Either may be omitted.
**Choosing a vaccine and lot** :
Both are instance-specific data, so look them up rather than hard-coding identifiers. A vaccine is only selectable on a note if it is active and carries an active CPT charge. See [Vaccine](/sdk/data-vaccine/) for the query.
**Manufacturer and expiration** :
When you supply a `lot_id` and leave `manufacturer` or `expiration_date` unset, the command fills them in from the lot. Anything you set explicitly is used as-is - including an explicit `None`, which is treated as a deliberate choice to leave the field empty rather than as an omission.
A `lot_number` is free text with no inventory record behind it, so nothing is derived from it; set `manufacturer` and `expiration_date` yourself if you want them recorded.
**Example** :
    ```python
    from datetime import date
    from canvas_sdk.commands.commands.immunize import ImmunizeCommand
    from canvas_sdk.v1.data import Vaccine, VaccineLot
    vaccine = Vaccine.objects.filter(active=True, cvx_code="135").first()
    lot = VaccineLot.objects.filter(vaccine__id=vaccine.id, on_hand_inventory__gt=0).first()
    # manufacturer and expiration_date are taken from the lot
    immunize = ImmunizeCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        vaccine_id=vaccine.id,
        lot_id=lot.id,
        sig="0.5 mL IM, left deltoid",
        consent_given=True,
        given_by_id="b8a7c6d5-4e3f-4a2b-9c1d-0e8f7a6b5c4d",
    )
    # A lot the instance does not stock: supply the details yourself
    immunize_unstocked = ImmunizeCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        vaccine_id=vaccine.id,

    from canvas_sdk.commands.constants import CodeSystems, Coding
    # SNOMED code
    InstructCommand(
        note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47',

###  LabOrder 
The `LabOrderCommand` is used to initiate a lab order through the Canvas system. This command requires detailed information about the lab partner, the tests being ordered, and the provider placing the order. Built-in validations ensure that:
  - The specified lab partner exists (whether provided by name or ID).
  - The ordered tests are available for the chosen lab partner.
**Electronic ordering:** LabOrder commands support the `send()` method for electronic ordering of signed orders directly to lab partners. However, electronic ordering has additional requirements:
  - Only lab partners with electronic ordering enabled support the `send()` method.
  - The command must be committed/signed before it can be sent electronically.
  - The patient must have an address and phone number on file.
  - The ordering provider must have an NPI.
**Command-specific parameters** :
Name| Type| Required to send| Description  
---|---|---|---  
`lab_partner`|  _string_| `true`| The [lab partner](/sdk/data-lab-partner-and-test/#labpartner) processing the order. Accepts either the lab partner's name or its unique identifier (ID).  
`tests_order_codes`|  _list[string]_| `true`| A list of codes or IDs for the [tests](/sdk/data-lab-partner-and-test/#labpartnertest-attributes) being ordered. The system verifies that each provided value corresponds to an available test for the specified lab partner.  
`ordering_provider_key`|  _string_| `false`| The [Staff](/sdk/data-staff/#staff) `id` of the provider ordering the tests.  
`diagnosis_codes`|  _list[string]_| `false`| ICD-10 Diagnosis codes justifying the lab order. Search with the [ICD-10 condition endpoint](/sdk/utils/#get-icdcondition--icd-10-conditions).  
`fasting_required`|  _boolean_| `false`| Indicates if fasting is required for the tests.  
`comment`|  _string_| `false`| Additional comments related to the lab order (max length: 128 characters).  
**Command-specific actions** :
Action Name| Available When| Description  
---|---|---  
`sign_send_action`| command is staged| Signs and immediately sends the order electronically to the lab partner.  
`send_action`| command is staged| Sends the order electronically to the chosen lab partner.  
`sign_action`| command is staged| Signs the order, transitioning it from staged to committed state.  
`print_requisition_form`| command is committed| Prints the order using a requisition-focused template for lab submission.  
`print_specimen_label`| command is committed| Prints the template using a specimen-focused template.  
`fax_requisition_form`| command is committed| Transmits the order electronically via fax.  
**ABN Workflow Actions**
When the ABN (Advance Beneficiary Notice) workflow is enabled, additional actions become available:
Action Name| Available When| Description  
---|---|---  
`send_abn_signed`| command is staged| Sends the order electronically after ABN requirements are met.  
`make_changes`| command is staged| Allows modifications to complete ABN requirements before sending.  
####  Validations 
  - **Lab Partner Validation:** The system checks that the provided `lab_partner` (by name or ID) exists in the system. If no matching lab partner is found, a validation error is raised.
  - **Tests Order Codes Validation:** Each test code or ID in `tests_order_codes` is verified against the tests available for the specified lab partner. If one or more tests cannot be found, the error will indicate which codes or IDs are missing.
**Example** :
    ```python
    from canvas_sdk.commands import LabOrderCommand
    from canvas_sdk.v1.data.lab import LabPartner, LabPartnerTest
    partner = LabPartner.objects.first()
    tests = [test.order_code for test in LabPartnerTest.objects.filter(lab_partner=partner)]
    LabOrderCommand(
      lab_partner=str(partner.id),
      tests_order_codes=tests,

    ```python
    from canvas_sdk.commands import PerformCommand
    from canvas_sdk.commands.constants import CodeSystems, Coding
    # Using a string (searches for matching procedures)
    PerformCommand(
        cpt_code="99213",
        notes="Patient presented with a common cold."
    )
    # Using a CPT code
    perform_cpt = PerformCommand(
        cpt_code=Coding(
            system=CodeSystems.CPT,
            code="99213",
            display="Office visit, established patient"
        ),
        notes="Annual wellness visit"
    )
    # Using unstructured (free text)
    perform_unstructured = PerformCommand(
        cpt_code=Coding(
            system=CodeSystems.UNSTRUCTURED,
            code="Custom procedure performed"
        ),
        notes="Non-standard procedure documentation"
    )
    ```
* * *
###  Plan 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`narrative`|  _string_| `true`| The narrative of the patient's plan.  
**Example** :
    ```python
    from canvas_sdk.commands import PlanCommand
    plan = PlanCommand(
        note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47',
        narrative='will return in 2 weeks to check on pain management'
    )
    ```
* * *
###  POCLabTest 
The `POCLabTestCommand` is used to document the results of a Point-of-Care (POC) lab test performed in the clinic — distinct from `LabOrder` (which sends tests to an external lab partner) and `LabReview` (which reviews returned results). The command captures the template used, the indications, individual measured values, and a free-text remarks field.
Built-in validations ensure that:
  - The provided `template` UUID resolves to an active POC [`LabReportTemplate`](/sdk/data-lab-report-template/#labreporttemplate).
  - Each `test_values` entry's `label` matches one of the template's [field labels](/sdk/data-lab-report-template/#labreporttemplatefield) (case-insensitive).
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`template`|  _UUID | string_| `true`| The UUID of the active POC [`LabReportTemplate`](/sdk/data-lab-report-template/#labreporttemplate). Accepts UUID instances or UUID-formatted strings.  
`indications`|  _list[string]_| `false`| ICD-10 diagnosis codes justifying the test. Search with the [ICD-10 condition endpoint](/sdk/utils/#get-icdcondition--icd-10-conditions).  
`test_values`|  _list[TestValue]_| `false`| The measured values, each tagged with its template-field label. See `TestValue` below.  
`remarks`|  _string (≤512)_| `false`| Free-text comments from the clinician.  
**Enums and Types** :
**`TestValue`**
A dataclass representing a single measured value within a POC lab test result.
Attribute| Type| Description  
---|---|---  
`label`|  _string_|  The template field's label (must match a field on the template).  
`value`|  _string_|  The measured value (as a string).  
`TestValue.to_dict()` returns the `{"label": ..., "value": ...}` dict shape consumed by the runtime.
**Helper methods** :
  - `set_test_value(label, value)` — Adds or replaces a test value by label. If a `TestValue` with the same `label` already exists on the command, it is replaced (so calling `set_test_value` twice with the same label leaves a single entry).
####  Validations 
  - **Template Validation:** The `template` UUID must resolve to a [`LabReportTemplate`](/sdk/data-lab-report-template/#labreporttemplate) that is `active=True` and `poc=True`. Templates from external lab partners or inactive templates are rejected.
  - **Test Values Validation:** Each `TestValue.label` must match (case-insensitive) the `label` of one of the resolved template's [fields](/sdk/data-lab-report-template/#labreporttemplatefield). Unknown labels cause a validation error.
The valid labels are the `label` of each [`LabReportTemplateField`](/sdk/data-lab-report-template/#labreporttemplatefield) on the template's [`fields`](/sdk/data-lab-report-template/#labreporttemplate) relation:
    ```python
    from canvas_sdk.v1.data import LabReportTemplate
    template = LabReportTemplate.objects.active().point_of_care().first()
    valid_labels = [field.label for field in template.fields.all()]
    ```
**Example** :
    ```python
    from canvas_sdk.commands import POCLabTestCommand
    from canvas_sdk.commands.commands.poc_lab_test import TestValue
    from canvas_sdk.v1.data import LabReportTemplate
    template = LabReportTemplate.objects.active().point_of_care().first()
    command = POCLabTestCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        template=template.id,
        indications=["E11.9"],
        test_values=[
            TestValue(label="pH", value="6.5"),
            TestValue(label="Glucose", value="120"),
        ],
        remarks="Sample collected mid-stream",
    )
    # Or via the helper (overwrites by label):
    command.set_test_value("pH", "6.8")
    ```
* * *
###  Prescribe 
**Electronic prescribing:** Prescribe commands support the `send()` method for electronic transmission of signed prescriptions. However, electronic prescribing has additional validations:
  - A pharmacy must be specified on the command before it can be sent.
  - The command must be committed/signed before it can be sent electronically.
  - The prescriber must have an SPI (Surescripts Prescriber Identifier) number on file, or the send is restricted with `eRx unavailable, prescriber missing SPI number`. SPI is a send requirement only: a prescriber without one can still review and sign the prescription.
  - For a controlled substance, the prescriber must be enrolled in EPCS, or the send is restricted with `eRx unavailable, prescriber not enrolled in EPCS`.
  - For a controlled substance (a medication with a DEA schedule), the patient's [sex at birth](/sdk/data-patient/#sexatbirth) must be male or female, or the send is restricted with `eRx unavailable, patient sex at birth must be male or female`.
These validations apply to Refill and AdjustPrescription as well, and in the Canvas UI as well as through the SDK — in the UI a restricted prescription offers no send action at all.
**Overriding the prescriber address:** By default, the prescriber address transmitted on the prescription is derived from the prescriber's primary practice location. For workflows where a provider works across multiple offices — for example white bagging, where the medication ships to the office where the patient is being seen — pass a `practice_location_override` to `send()` to use a specific practice location's address instead:
    ```python
    from canvas_sdk.commands import PrescribeCommand
    def compute():
        existing_prescribe = PrescribeCommand(command_uuid='e32b85d9-ccb7-4e4f-a0e5-8783ed2d9528')
        return [existing_prescribe.send(practice_location_override='a1b2c3d4-e5f6-7890-abcd-ef1234567890')]
    ```
  - `practice_location_override` is the `id` of a [PracticeLocation](/sdk/data-practicelocation/#practicelocation). When set, that location's business name, phone, fax, and street address replace the prescriber's default on the outgoing prescription.
  - If the id does not correspond to an existing practice location, the send raises an error rather than falling back to the default address.
  - The override applies only to `send()`-initiated (plugin-driven) prescriptions. It does not affect prescriptions a clinician sends from the charting UI.
**Command-specific parameters** :

**Examples**
** _Option 1: Standard Prescription (FDB Code)_**
    ```python
    from canvas_sdk.commands.constants import ClinicalQuantity
    from canvas_sdk.commands import PrescribeCommand
    prescription = PrescribeCommand(
        fdb_code="216092",
        icd10_codes=["R51"],
        sig="Take one tablet daily after meals",
        days_supply=30,
        quantity_to_dispense=30,
        type_to_dispense=ClinicalQuantity(
            representative_ndc="12843016128",
            ncpdp_quantity_qualifier_code="C48542"
        ),
        refills=3,
        substitutions=PrescribeCommand.Substitutions.ALLOWED,
        pharmacy="pharmacy_ncpdp_id",
        prescriber_id="a7c2e9d1-3b4f-4a6c-8e0d-5f1a2b3c4d5e",
        supervising_provider_id='c3d4e5f6-7a8b-4c9d-0e1f-2a3b4c5d6e7f',
        note_to_pharmacist="Please verify patient's insurance before processing."
    )
    ```
**_Option 2: Existing Compound Medication (by ID)_**
Note: `type_to_dispense` should not be provided for compound medications as this field will auto-populate in the command when it is inserted in the note
    ```python
    from canvas_sdk.commands.constants import ClinicalQuantity
    from canvas_sdk.commands import PrescribeCommand
    from canvas_sdk.v1.data.compound_medication import CompoundMedication as CompoundMedicationModel
    # Get an existing compound medication (let's assume it exists in the database)
    compound_med = CompoundMedicationModel.objects.filter(
        active=True,
        formulation="Testosterone 200mg/mL in Grapeseed Oil"
    ).first()
    prescription = PrescribeCommand(
        compound_medication_id=str(compound_med.id),
        icd10_codes=["R51"],
        sig="Take one tablet daily after meals",
        days_supply=30,
        quantity_to_dispense=30,
        refills=3,
        substitutions=PrescribeCommand.Substitutions.ALLOWED,
        pharmacy="pharmacy_ncpdp_id",
        prescriber_id="a7c2e9d1-3b4f-4a6c-8e0d-5f1a2b3c4d5e",
        supervising_provider_id='c3d4e5f6-7a8b-4c9d-0e1f-2a3b4c5d6e7f',
        note_to_pharmacist="Please verify patient's insurance before processing."
    )
    ```
**_Option 3: Create New Compound Medication Inline_**
    ```python
    from canvas_sdk.commands.constants import ClinicalQuantity
    from canvas_sdk.commands.commands.prescribe import PrescribeCommand, CompoundMedicationData
    from canvas_sdk.v1.data.compound_medication import CompoundMedication
    compound_medication_data = CompoundMedicationData(
        formulation="Testosterone 200mg/mL in Grapeseed Oil",
        potency_unit_code=CompoundMedication.PotencyUnits.GRAM,
        controlled_substance=CompoundMedication.ControlledSubstanceOptions.SCHEDULE_III,
        controlled_substance_ndc="12345678901",
        active=True,
    )
    prescription = PrescribeCommand(
        compound_medication_data=compound_medication_data,
        icd10_codes=["M79.3"],
        sig="Apply thin layer to affected area twice daily",
        days_supply=30,
        quantity_to_dispense=30,
        refills=3,
        substitutions=PrescribeCommand.Substitutions.ALLOWED,
        pharmacy="pharmacy_ncpdp_id",
        prescriber_id="a7c2e9d1-3b4f-4a6c-8e0d-5f1a2b3c4d5e",
        supervising_provider_id='c3d4e5f6-7a8b-4c9d-0e1f-2a3b4c5d6e7f',
        note_to_pharmacist="Please verify patient's insurance before processing."
    )
    ```
**Validation Notes**
  - Medication Type Validation: Exactly one of fdb_code, compound_medication_id, or compound_medication_data must be provided
  - Compound Medication ID: When using compound_medication_id, the system validates that the compound medication exists
  - Compound Medication Data: When using compound_medication_data:
    - All required fields in the dataclass must be provided
    - If controlled substance is not "N" (None), then controlled_substance_ndc is required
    - The formulation is limited to 105 characters
    - Any dashes in the NDC are automatically removed
    - Before creating a new compound medication, the system checks if a compound with the same formulation and potency unit code already exists. If it does, it reuses the existing compound medication instead of creating a new one.
  - Potency Unit and Controlled Substance Values: Must use valid enum values from PotencyUnit and ControlledSubstanceSchedule
**Limits**
A prescription has to fit what can be transmitted to the pharmacy, so four fields are bounded. These apply to Refill and AdjustPrescription as well, which share the fields.
Field| Limit  
---|---  
`sig`| 1000 characters  
`note_to_pharmacist`| 210 characters  
`refills`| 0 to 99  
`quantity_to_dispense`| greater than 0  
All four are checked when the command is turned into an effect, not when the field is set. Building a command up field by field therefore never fails part-way through, and `originate()` or `edit()` reports every value that is out of bounds at once:
    ```python
    from canvas_sdk.commands import PrescribeCommand
    def compute():
        prescribe = PrescribeCommand(note_uuid='c4d1e4b8-6a5f-4b3a-9e2d-7f8a9b0c1d2e')
        # Neither assignment raises.
        prescribe.refills = 100
        prescribe.quantity_to_dispense = 0
        # This raises a validation error naming both values.
        return [prescribe.originate()]
    ```
* * *
###  PhysicalExam 
**Note:** The PhysicalExamCommand is a subclass of the QuestionnaireCommand, so it supports all the questionnaire features. That includes recording responses either with the `answers` parameter or with the `questions` property and `add_response()` — see Recording responses.
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`questionnaire_id`|  _string_| `true`| The id of the [Questionnaire](/sdk/data-questionnaire/#questionnaire) being answered by the patient.  
`answers`|  _list ofAnswer_| `false`| The responses to record, one per question. Defaults to an empty list.  
####  Toggle Questions Feature 
The PhysicalExamCommand and the ReviewOfSystemsCommand both support toggling questions on/off, so practitioners can enable or disable specific questions based on patient relevance. The methods, property, and behavior described here are identical for both commands.
The following methods are available. In each, `question_id` is the [Question](/sdk/data-questionnaire/#question) `dbid` (an integer, accepted as `int` or `str`):
**Methods** :
Method| Parameters| Returns| Description  
---|---|---|---  
`is_question_enabled`| `question_id: str` or `int`| `bool`| Check if a specific question is enabled (not skipped).  
`set_question_enabled`| `question_id: str` or `int, enabled: bool`| `None`| Enable or disable a specific question.  
**Properties** :
Property| Type| Description  
---|---|---  
`question_toggles`| `dict`| All current toggle states, mapping `question_id` → `enabled` — e.g. `{"12": True, "13": False, "14": True}`.  
**Example - Working with Existing Commands** :
A common use case is retrieving existing PhysicalExam commands from a note and modifying their toggle states. Here's how to work with the Canvas SDK data objects:
    ```python
    from canvas_sdk.commands import PhysicalExamCommand
    from canvas_sdk.v1.data import Command, Note
    from logger import log
    # Get existing physical exam commands from a note
    note = Note.objects.get(id="ff287601-fff4-46c4-b21f-04760e88adf1")
    physical_exam_commands = Command.objects.filter(
        note=note,
        schema_key="exam"  # Physical exam commands have schema_key "exam"
    ).all()
    effects = []
    for command in physical_exam_commands:
        # The command.data contains the question responses and skip states
        # Example structure of command.data:
        # {
        #     "questionnaire": {"value": "83d93454-25a9-404d-83a5-e0ed2ec3af00"},
        #     "question-12": "70",  # Body length response
        #     "question-13": None,   # Head circumference (no response)
        #     "skip-12": True,   # Body length is enabled (counterintuitive: skip=True means enabled)
        #     "skip-13": False,  # Head circumference is disabled
        # }
        # Create a PhysicalExamCommand instance from the existing command
        exam = PhysicalExamCommand(command_uuid=str(command.id))
        # The exam.questions property gives you access to all questions with their IDs
        log.info(f"Processing Physical Exam Command: {exam.command_uuid}")
        for question in exam.questions:
            # Each question object has an 'id' property with the question ID
            question_id = question.dbid
            if exam.is_question_enabled(question_id):
                log.info(f"Question {question_id} is enabled")
                # Check if there's a response in the command data
                question_key = f"question-{question_id}"
                if question_key in command.data:
                    response = command.data[question_key]
                    if response:
                        log.info(f"Response: {response}")
        # Example: Enable all questions that have responses, disable those without
        for question in exam.questions:
            question_id = question.dbid
            question_key = f"question-{question_id}"
            # Check if question has a response in command.data
            has_response = question_key in command.data and command.data[question_key]
            if has_response:
                exam.set_question_enabled(question_id, True)
            else:
                # Optionally disable questions without responses
                exam.set_question_enabled(question_id, False)
        effects.append(exam.edit())
    ```
**Example - Creating a New Physical Exam** :
    ```python
    from canvas_sdk.commands import PhysicalExamCommand
    # Create a new physical exam
    exam = PhysicalExamCommand(
      note_uuid='a229456f-c10d-4f85-a04e-e8675d4e56dd',
      questionnaire_id='83d93454-25a9-404d-83a5-e0ed2ec3af00',
    )
    questions = exam.questions  # Retrieve the list of questions
    # Returns: [
    #               Question(
    #                       self.name='question-12',
    #                       self.label='Body length (in)',
    #                       self.type='TXT',
    #                       self.options=[ResponseOption(self.dbid=38, self.name='Body length (in)', self.code='8306-3', self.value='')],
    #                       self.response=None
    #               ),
    #               Question(
    #                       self.name='question-13',
    #                       self.label='Head circumference (cm)',
    #                       self.type='TXT', self.options=[ResponseOption(self.dbid=39, self.name='Head circumference (cm)', self.code='8287-5', self.value='')],
    #                       self.response=None
    #               )
    # Check if a question is enabled
    if exam.is_question_enabled("12"):
      print("Body length question is enabled.")
    # Disable irrelevant questions
    exam.set_question_enabled("13", False)
    # Get all toggle states
    states = exam.question_toggles
    # Returns: {"12": True, "13": False, "14": True, ...}, where keys are question IDs and values are enabled states.
    # Working with existing exam - toggle states are preserved
    existing_exam = PhysicalExamCommand(command_uuid='d4e5f6a7-8b9c-4d0e-1f2a-3b4c5d6e7f80')
    # All previously set toggle states are automatically loaded
    ```

###  Questionnaire 
####  Overview 
The `QuestionnaireCommand` is used to present a questionnaire to a patient and commit their responses to an interview. It requires the ID of the questionnaire
**Automatic Questionnaire ID Loading** : When instantiating a QuestionnaireCommand with an existing `command_uuid`, the questionnaire_id will be automatically loaded from the database if not explicitly provided. This means you don't need to specify the questionnaire_id when working with existing commands.
In addition to the basic parameters, this command records responses in either of two ways:
  - **The`answers` parameter** — you pass the responses in, one per question, and the command works out how to apply each one. Nothing in your code branches on a question's type. Use this when you already have the question and option ids.
  - **The`questions` property with `add_response()`** — you read the questionnaire's questions off the command and record a response on each question object. The keyword you pass differs by question type, so your code branches on it. Use this when you need to inspect the questions or their options at runtime to decide what to answer.
Both arrive at the same result, and they can be combined. `answers` is applied when the command's effect is built: it replaces whatever was recorded on the questions it names, and leaves a response recorded with `add_response()` on any other question alone. `answers` is not itself carried in the effect.
**Recording responses with`answers`**
The `answers` parameter takes a list of `Answer` objects, one per question. Each names a question and the response it takes; the command looks up the question, dispatches on its type, and resolves an option id to the option itself. A question id that is not in the questionnaire, an option id the question does not offer, or a response the question's type does not allow raises a `ValueError` when the effect is built.
**`Answer` fields**:
Name| Type| Required| Description  
---|---|---|---  
`question_id`|  _integer_| `true`| The [Question](/sdk/data-questionnaire/#question) `dbid`.  
`response`|  _string_ , _integer_ , or _list ofSelection_| `true`| Text for a text question, a number for an integer question, a [ResponseOption](/sdk/data-questionnaire/#responseoption) `dbid` for a radio question, an ISO 8601 `YYYY-MM-DD` string for a date question, or a list of `Selection` objects for a checkbox question.  
A checkbox question is the only kind whose responses carry comments, and each of its selections carries its own — so a comment belongs to a `Selection` rather than to the answer as a whole.
> **Warning:** A date answer given through `answers` must be a string. `response` accepts a string, an integer or a list of `Selection`, so a `datetime.date` is refused. The question's own `add_response(date=...)` is the path that takes a `datetime.date` or a `datetime.datetime`.
**`Selection` fields**:
Name| Type| Required| Description  
---|---|---|---  
`option_id`|  _integer_| `true`| The [ResponseOption](/sdk/data-questionnaire/#responseoption) `dbid` to tick.  
`comment`|  _string_| `false`| What this selection is qualified with.  
`selected`|  _boolean_| `false`| Defaults to `true`. Set it to `false` to untick the option — one a payload says nothing about keeps the state it already had.  
**Recording responses with`questions` and `add_response()`**
Retrieve the list of questions via the `questions` property and record responses for each question using the question object's `add_response()` method. Each question type enforces its expected response format:
  - **Text questions (TYPE_TEXT):** Accept a keyword argument `text` (a string).
  - **Integer questions (TYPE_INTEGER):** Accept a keyword argument `integer` (a value convertible to an integer; a non-convertible value raises an error).
  - **Radio questions (TYPE_RADIO):** Accept a keyword argument `option` (a `ResponseOption` instance); only one option may be selected.
  - **Checkbox questions (TYPE_CHECKBOX):** Accept a keyword argument `option` (a `ResponseOption` instance) along with an optional boolean `selected` (defaulting to True) and an optional string `comment`. Multiple responses can be recorded.
  - **Date questions (TYPE_DATE):** Accept a keyword argument `date` (a `datetime.date`, a `datetime.datetime` normalized to its date, or an ISO 8601 date string `YYYY-MM-DD`). The value is stored as a normalized `YYYY-MM-DD` string; a string carrying a time component, an unparseable string, or a wrong type raises an error.
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`questionnaire_id`|  _string_| `true`| The id of the [Questionnaire](/sdk/data-questionnaire/#questionnaire) being answered by the patient.  
`answers`|  _list ofAnswer_| `false`| The responses to record, one per question. Defaults to an empty list.  
**Example** — instantiating an empty questionnaire:
    ```python
    from canvas_sdk.commands import QuestionnaireCommand
    questionnaire = QuestionnaireCommand(
        note_uuid='8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47',
        questionnaire_id='c1a2b3d4-e5f6-4a7b-8c9d-0e1f2a3b4c5d'
    )
    ```
####  Usage Example 
Below is an example that answers a questionnaire with `answers`. Each `Answer` names a question by its `dbid` and gives the response in the form that question takes, so nothing branches on the question's type:
    ```python
    import uuid
    from canvas_sdk.commands.commands.questionnaire import Answer, QuestionnaireCommand, Selection
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Note, Questionnaire
    class MyHandler(BaseHandler):
        def compute(self) -> list[Effect]:
          questionnaire = Questionnaire.objects.filter(name="Exercise").first()
          note = Note.objects.last()
          command = QuestionnaireCommand(
              note_uuid=str(note.id),
              questionnaire_id=str(questionnaire.id),
              command_uuid=str(uuid.uuid4()),
              answers=[
                  # A text question.
                  Answer(question_id=12, response="Thanks for all the fish"),
                  # An integer question.
                  Answer(question_id=13, response=42),
                  # A radio question, answered with the id of one of its options.
                  Answer(question_id=14, response=101),
                  # A date question. Give the date as a string, not a datetime.date.
                  Answer(question_id=15, response="2026-07-14"),
                  # A checkbox question, answered with one Selection per option ticked.
                  Answer(
                      question_id=16,
                      response=[
                          Selection(option_id=201),
                          Selection(option_id=202, comment="Don't panic"),
                      ],
                  ),
              ],
          )
          # Because we're directly setting a command_uuid, we can return both originate and edit.
          return [command.originate(), command.edit()]
    ```
An option id that the question does not offer, or a question id that is not in the questionnaire, raises a `ValueError` rather than recording something the questionnaire does not define.
Below is the same thing written the other way, retrieving the questions and adding responses to them based on their type:
    ```python
    import uuid
    from canvas_sdk.commands.commands.questionnaire import QuestionnaireCommand
    from canvas_sdk.commands.commands.questionnaire.question import ResponseOption
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Note, Questionnaire
    class MyHandler(BaseHandler):
        def compute(self) -> list[Effect]:
          q = Questionnaire.objects.filter(name="Exercise").first()
          note = Note.objects.last()
          # Create a QuestionnaireCommand instance.
          command = QuestionnaireCommand(questionnaire_id=str(q.id))
          command.note_uuid = str(note.id)
          command.command_uuid = str(uuid.uuid4())
          # Alternatively you can just retrieve an existing questionnaire command, and only return an `edit` effect.
          # Retrieve the list of questions.
          questions = command.questions
          # Record responses for each question.
          for question in questions:
              if question.type == ResponseOption.TYPE_TEXT:
                  # For text questions, pass a 'text' keyword argument.
                  question.add_response(text=f"Thanks for all the fish")
              elif question.type == ResponseOption.TYPE_INTEGER:
                  # For integer questions, pass an 'integer' keyword argument.
                  question.add_response(integer=42)
              elif question.type == ResponseOption.TYPE_RADIO:
                  # For radio questions, pass an 'option' keyword argument (a ResponseOption instance).
                  first_option = question.options[0]
                  question.add_response(option=first_option)
              elif question.type == ResponseOption.TYPE_CHECKBOX:
                  # For checkbox questions, add responses with option, selected flag, and optionally a comment.
                  first_option = question.options[0]
                  last_option = question.options[-1]
                  question.add_response(option=first_option, selected=True, comment="Don't panic")
                  question.add_response(option=last_option, selected=True)
              elif question.type == ResponseOption.TYPE_DATE:
                  # For date questions, pass a 'date' keyword argument.
                  question.add_response(date="2026-01-15")
          # Because we're directly setting a command_uuid, we can return both originate and edit.
          return [command.originate(), command.edit()]
    ```
####  Explanation 
  - **Retrieving Questions:** The `questions` property returns a list of question objects created from the questionnaire's data.
  - **Recording Responses:** Either set `answers` and let the command resolve each response against its question, or record them one at a time. Each question object provides an `add_response()` method that enforces the correct response format:
    - For **TextQuestion** , you must pass a `text` parameter.
    - For **IntegerQuestion** , you must pass an `integer` parameter.
    - For **RadioQuestion** , you must pass an `option` parameter (a `ResponseOption` instance) that corresponds to one of the allowed options.
    - For **CheckboxQuestion** , you must pass an `option` parameter along with an optional `selected` flag (defaulting to True) and an optional `comment`. Multiple responses can be recorded for checkbox questions.
    - **Note for Checkboxes:** Only the responses explicitly provided in the command payload will be updated in the UI. If a checkbox response is already selected and is not sent as unselected in the payload, its state remains unchanged.
    - For **DateQuestion** , you must pass a `date` parameter (a `datetime.date`, a `datetime.datetime`, or an ISO 8601 date string), stored as a normalized `YYYY-MM-DD` string.
  - **Creating and Editing:** When creating a new questionnaire command, you must explicitly set a unique `command_uuid`. Providing this UUID enables you to originate the command within the note and then subsequently edit it with detailed responses in the same protocol execution.
  - This approach is necessary because given the dynamic nature of the questionnaire command, the initial creation (origination) only includes the questionnaire ID. Once the command has been originated, you can immediately follow up with an edit to populate it with the patient's responses.
  - If you are looking to insert a committed questionnaire command, you'll need to return three effects:
    - An `.originate()` to insert the command and select the questionnaire
    - An `.edit()` to populate the responses
    - A `.commit()` to commit the command

###  Reference 
Embeds a diagnostic view in the note. A diagnostic view is a saved combination of lab tests and questionnaire codes configured on your instance; referencing one renders that patient's results for those codes as a timeseries inside the note, so a reviewer sees the trend without leaving the chart.
The command renders as a read-only table. There are no fields for a user to fill in, so the diagnostic view has to be chosen by whatever inserts the command — a user can only commit or delete it, and enter it in error once committed.
Unlike ChartSectionReview, it is not committed on origination: it stays staged until you pass `commit=True` to `originate()` or send a separate `commit()`.
> **Warning:** The rendered name and table are derived from the diagnostic view when the command is originated, and are not recalculated afterwards. Pointing an existing command at a different diagnostic view with `edit()` leaves the previous view's name and table on display. To change the view, delete the command and originate a new one.
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`diagnostic_view_id`|  _UUID_ or _string_| `true`| The id of the [DiagnosticView](/sdk/data-diagnostic-view/#diagnosticview) to embed. An id that does not match a diagnostic view on the instance is discarded, leaving the command with no view to render.  
**Example** :
    ```python
    from canvas_sdk.commands import ReferenceCommand
    from canvas_sdk.v1.data import DiagnosticView
    def compute():
        a1c_view = DiagnosticView.objects.filter(name="Hemoglobin A1c").first()
        if not a1c_view:
            return []
        reference = ReferenceCommand(
            note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
            diagnostic_view_id=a1c_view.id,
        )
        return [reference.originate(commit=True)]
    ```

`communication_method`|  _ReportReviewCommunicationMethod enum_| `false`| Method for patient communication. Must be one of `ReportReviewCommunicationMethod`.  
`linked_items_urns`|  _list[string]_| `false`| List of URNs for items linked to the review.

    )
    ```
* * *
###  Resolve Condition 
**Command-specific parameters** :
Name| Type| Required to commit| Description  
---|---|---|---  
`condition_id`|  _string_| `true`| The id of the [Condition](/sdk/data-condition/#condition) being resolved. Must be an **active** condition on that patient's chart — committed, not entered in error, and not already resolved.  
`show_in_condition_list`|  _boolean_| `false`| Determines whether the condition remains visible in patient chart summary.  
`rationale`|  _string_| `false`| Additional context.  
    ```python

`answers`|  _list ofAnswer_| `false`| The responses to record, one per question. Defaults to an empty list.  
####  Toggle Questions Feature 
The ReviewOfSystemsCommand supports the same question-toggling functionality as the PhysicalExamCommand, allowing practitioners to enable or disable specific system-review questions based on patient relevance. The available methods (`is_question_enabled`, `set_question_enabled`) and the `question_toggles` property are documented once under the PhysicalExam Toggle Questions Feature — they behave identically here.
**Example** :
    ```python
    from canvas_sdk.commands import ReviewOfSystemsCommand
    # Create a new review of systems
    ros = ReviewOfSystemsCommand(
      note_uuid='8a18931a-acd9-474b-9070-ccd6fd472313',
      questionnaire_id='ed92577b-a023-4370-bc85-2b57e8afc4d8',
    )
    questions = ros.questions  # Retrieve the list of questions

##  Command Constants 
The `canvas_sdk.commands.constants` module provides essential classes and enumerations used across various Canvas SDK command implementations. These constants ensure consistency and provide structured data types for common medical and administrative elements.
###  ClinicalQuantity 
`ClinicalQuantity` represents detailed information about the form or unit of medication, particularly for prescription-related commands.
Field Name| Type| Required| Description

# Provider Companion

Source: https://docs.canvasmedical.com/sdk/companion/

The **Provider Companion** is a mobile-optimized, provider-facing web app that runs alongside Canvas. It's designed for the phone-in-hand moments in a clinician's day — looking something up between rooms, triaging a message list, checking in on a patient's tasks — rather than the sit-down charting workflows the desktop app covers.
Your plugins can contribute applications to the companion just like they do to the desktop. This page covers how plugins integrate, the three companion-specific application scopes, and how to share code when you want the same plugin to work across multiple scopes.
##  Accessing the companion 
The companion lives at `/companion/` on your Canvas instance:
    ```text
    https://<instance>.canvasmedical.com/companion/
    ```
Any staff user who can log in to the desktop Canvas app can log in to the companion with the same credentials. Patients don't have access — it's a provider surface only.
##  How plugins extend the companion 
Canvas plugins contribute embedded apps through the `Application` handler — a Python class with an `on_open()` method that returns a URL for Canvas to iframe into its UI. Which surface your app appears on is controlled by the `scope` value in your plugin's `CANVAS_MANIFEST.json`. Companion apps work exactly the same way; they just use one of three companion-specific `scope` values. If you haven't built an embedded app before, start with the [Applications](/sdk/handlers-applications/) page — this page assumes you know the basics and focuses on what's companion-specific.
There are three companion scopes:
Scope| Where the app shows up  
---|---  
`provider_companion_global`| Icon in the app launcher on the companion's main page, outside of any patient context  
`provider_companion_patient_specific`| Tab on the patient page, next to the built-in Timeline tab  
`provider_companion_note_specific`| Tab within an opened note on the patient page  
When a user opens your app, Canvas fires an `APPLICATION__ON_OPEN` event and your handler's `on_open()` runs. Return a `LaunchModalEffect` pointing at whatever URL you want embedded — typically a page served by a SimpleAPI handler in the same plugin.
##  `provider_companion_global`
Global-scope apps appear in the companion's launcher on the main page. They run with no patient or note context — they're the right surface for workflows that span many patients, or administrative work that isn't tied to a chart.

###  Event context 
`self.event.context` contains the acting user but no patient or note keys.
###  Use cases 
  - A **task queue** showing every task assigned to the logged-in provider across all patients.
  - A **schedule viewer** for the day's appointments.
  - A **secure chat** for the care team.
  - An **administrative dashboard** — e.g. open lab orders awaiting review.
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class TaskDashboardGlobal(Application):
        """Companion global app — every task for the logged-in provider."""
        def on_open(self) -> Effect:
            return LaunchModalEffect(
                url="/plugin-io/api/task_dashboard/app/tasks",
                target=LaunchModalEffect.TargetType.DEFAULT_MODAL,
            ).apply()
    ```

The `TaskDashboardAPI` class is the [SimpleAPI handler](/sdk/handlers-simple-api/) that actually serves the page `on_open` iframes. `on_open` only returns the launch effect; the page itself has to be served by something, and that something is a SimpleAPI handler registered here.
##  `provider_companion_patient_specific`
Patient-scope apps appear as tabs on the patient page. Your tab sits next to the built-in Timeline tab, and when the user taps it, your handler's `on_open()` fires with the patient in `event.context`.

###  Event context 
    ```python
    self.event.context["patient"]["id"]  # Patient id (UUID string)
    ```
###  Use cases 
  - A **chart summary** of conditions, meds, allergies, vitals, etc. for the open patient.
  - A **risk-score panel** tied to the patient.
  - A **care-plan checklist** for this patient's current programs.
  - A **patient-scoped task list** — the same tasks view as the global app, but filtered to just this patient's tasks.
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class TaskDashboardPatient(Application):
        """Companion patient app — tasks filtered to one patient."""
        def on_open(self) -> Effect:

##  `provider_companion_note_specific`
Note-scope apps appear as tabs inside an opened note on the patient page. Use these for workflows scoped to a single encounter. Both the patient and the note are passed in the event context.
![](/assets/images/sdk/companion/note.png) ![](/assets/images/sdk/companion/note-app.png)
###  Event context 
    ```python
    self.event.context["patient"]["id"]  # Patient id (UUID string)
    self.event.context["note"]["id"]     # Note UUID
    ```
###  Use cases 
  - A **documentation assistant** that reads the note's commands and suggests improvements.
  - A **coding / billing helper** that computes E&M level from the note's content.
  - A **visit-specific questionnaire** the provider fills out per encounter.
  - An **inline scribe** that writes note content from dictation or an LLM.
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class ScribeAssistant(Application):
        """Companion note app — inline scribe for the open note."""
        def on_open(self) -> Effect:
            patient_id = self.event.context.get("patient", {}).get("id", "")
            note_id = self.event.context.get("note", {}).get("id", "")
            return LaunchModalEffect(

    }

###  Originating commands on the note 
The note scope's real payoff is that your app can contribute to the note it's running in. Take the `note_uuid` from the event context, build an SDK command with it, and return the command's `originate()` effect alongside your JSON response — the platform will materialize the command in the note after your handler returns.
    ```python
    from http import HTTPStatus
    from canvas_sdk.commands.commands.vitals import VitalsCommand
    from canvas_sdk.effects.simple_api import JSONResponse
    from canvas_sdk.handlers.simple_api import SimpleAPI, StaffSessionAuthMixin, api
    class VitalsEntryAPI(StaffSessionAuthMixin, SimpleAPI):
        PREFIX = "/app"
        @api.post("/vitals")
        def submit(self):
            note_id = self.request.query_params.get("note_id", "")
            body = self.request.json() or {}
            command = VitalsCommand(
                note_uuid=note_id,
                blood_pressure_systole=body.get("bp_sys"),
                blood_pressure_diastole=body.get("bp_dia"),
                pulse=body.get("pulse"),
            )
            return [
                command.originate(),
                JSONResponse(
                    {"status": "submitted"},
                    status_code=HTTPStatus.ACCEPTED,
                ),
            ]
    ```
The Application passes `note_id` through to the iframe on the launch URL's query string; the iframe sends it along on the POST to `/vitals`. The same pattern works for any SDK command that exposes an `originate()` method — assessments, prescriptions, lab orders, imaging orders, etc.
**Attribution is the plugin author's responsibility.** Commands don't carry an explicit originator field; the platform attributes them to whoever the authenticated session belongs to when the effect is applied. The [`StaffSessionAuthMixin`](/sdk/handlers-simple-api-http/#staff-session) on the handler above ensures the request is gated on a logged-in staff session, so the originated command is attributed to that staff user rather than a generic plugin service identity. If your handler doesn't enforce a staff session, commands it originates won't be tied to the provider using the app — gate every command-originating route with `StaffSessionAuthMixin` (or a stricter equivalent).
##  Sharing code across scopes 
You don't need a separate plugin per scope — a single plugin can register several applications, all backed by the same SimpleAPI handler and the same UI bundle. The Application subclasses differ only in which scope they declare and what they put in the launch URL's query string; the shared handler branches on what it receives.
The task dashboard is a natural example. The global view and the patient-scoped view show the same UI — a list of task cards — but one shows every task assigned to the provider and the other shows only tasks tied to the open patient. They can share everything except the scope declaration and one query-string parameter.

      "diagram": false,

    }
    ```
###  Shared SimpleAPI handler 
The handler serves the same HTML for both scopes and branches on `patient_id` in its data endpoint: present → filter to that patient, absent → return the provider's entire task queue.
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects.simple_api import HTMLResponse, JSONResponse
    from canvas_sdk.handlers.simple_api import SimpleAPI, StaffSessionAuthMixin, api
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data.task import Task
    class TaskDashboardAPI(StaffSessionAuthMixin, SimpleAPI):
        PREFIX = "/app"
        @api.get("/tasks")
        def page(self):
            return [HTMLResponse(
                render_to_string("static/tasks.html"),
                status_code=HTTPStatus.OK,
            )]
        @api.get("/tasks/data.json")
        def data(self):
            user_id = self.request.headers["canvas-logged-in-user-id"]
            patient_id = self.request.query_params.get("patient_id")
            tasks = Task.objects.filter(assigned_to_id=user_id)
            if patient_id:
                tasks = tasks.filter(patient__key=patient_id)
            return [JSONResponse(
                {"tasks": [serialize(t) for t in tasks]},
                status_code=HTTPStatus.OK,
            )]
    ```
The HTML/JS bundle (served by `/app/tasks`) fetches `/app/tasks/data.json` relative to its own URL, so it gets the right slice of tasks without knowing which scope launched it — the scope is encoded in whether the Application handler appended `?patient_id=...` to the launch URL.
This pattern generalizes: any time the _same UI_ works on a filtered or unfiltered dataset, you can register one Application per scope and share the handler, templates, and client-side code underneath.
##  Dismissing your modal 
Shortly after your iframe loads, Canvas transfers a `MessagePort` to it via a `postMessage` event. The plugin stores that port and posts `{type: 'CLOSE_MODAL'}` through it whenever it wants to dismiss itself — typically right after a successful form submit, or from a Cancel button.
    ```javascript
    let messagePort = null;
    window.addEventListener('message', (event) => {
        if (event.data?.type === 'INIT_CHANNEL' && event.ports?.[0]) {
            messagePort = event.ports[0];
            messagePort.start();
        }
    });
    function closeModal() {
        if (messagePort) {
            messagePort.postMessage({ type: 'CLOSE_MODAL' });
        } else {
            window.close();  // fallback if the port never arrived
        }
    }
    ```
Register the `message` listener at module scope, not inside a `DOMContentLoaded` handler — the port can arrive before your DOM is ready, and a listener attached later will miss it.
##  Async effects from SimpleAPI handlers 
Effects returned from a SimpleAPI route execute **after** the handler returns — they're dispatched to a platform worker, not applied inside your handler's transaction. That means you can't emit e.g. `Patient(...).create()` and then query for the new patient in the same request — the effect hasn't been processed yet and the record doesn't exist.
If you need the new record's UUID (for example to deep-link to it), do the lookup on a follow-up request from the iframe. The simplest shape: `POST /create` emits the effect and returns `202 Accepted` with everything needed to identify the new record; the iframe polls a separate `GET /find` endpoint until the record appears (or a short timeout fires).
    ```python
    import datetime
    from http import HTTPStatus
    from canvas_sdk.effects.patient import Patient as PatientEffect
    from canvas_sdk.effects.simple_api import JSONResponse
    from canvas_sdk.handlers.simple_api import SimpleAPI, StaffSessionAuthMixin, api
    from canvas_sdk.v1.data.patient import Patient
    class RegisterPatientAPI(StaffSessionAuthMixin, SimpleAPI):
        PREFIX = "/app"
        @api.post("/create")
        def create(self):
            body = self.request.json() or {}
            # ... validate the submission ...
            effect = PatientEffect(
                first_name=body["first_name"],
                last_name=body["last_name"],
                birthdate=body["birth_date"],
            ).create()
            return [
                effect,
                JSONResponse({
                    "status": "submitted",
                    "lookup_params": {
                        "first_name": body["first_name"],
                        "last_name": body["last_name"],
                        "birth_date": body["birth_date"],
                    },
                    "lookup_started_at":
                        datetime.datetime.now(datetime.timezone.utc).isoformat(),
                }, status_code=HTTPStatus.ACCEPTED),
            ]
        @api.get("/find")
        def find(self):
            params = self.request.query_params
            found = (
                Patient.objects
                .filter(
                    first_name=params["first_name"],
                    last_name=params["last_name"],
                    birth_date=params["birth_date"],
                    created__gte=params["after"],
                )
                .order_by("-created")
                .first()
            )
            return [JSONResponse(
                {"patient_id": str(found.id) if found else None},
                status_code=HTTPStatus.OK,
            )]
    ```
On the iframe, poll `/find` at ~500 ms intervals for ~5 s. On the first hit, deep-link to the new record. On timeout, surface a clear error message — the effect failed and there's nothing to link to. Don't claim success before the lookup confirms the record exists.
##  Common patterns 
The conventions are the same as any other SDK application — the companion just chooses where and when to render your iframe.
  - **Serve your UI from a[SimpleAPI handler](/sdk/handlers-simple-api/)** in the same plugin. `on_open()` returns a `LaunchModalEffect` pointing at a URL like `/plugin-io/api/<plugin_name>/...`.
  - **Authenticate with[`StaffSessionAuthMixin`](/sdk/handlers-simple-api-http/#staff-session).** The companion is staff-only, so every request hitting your plugin's SimpleAPI should be gated on a valid staff session. Mix the class in instead of writing your own `authenticate()` — it rejects non-staff sessions (including patient-portal sessions) up front:
        ```python
        from canvas_sdk.handlers.simple_api import SimpleAPI, StaffSessionAuthMixin
        class TaskDashboardAPI(StaffSessionAuthMixin, SimpleAPI):
            PREFIX = "/app"
            # ... routes ...
        ```
The logged-in user is then available via `self.request.headers["canvas-logged-in-user-id"]`.
  - **Push live updates with a plugin-owned WebSocket.** If your app needs to stay in sync when data changes, add a `BaseHandler` that listens for the relevant domain events and broadcasts on a channel the iframe subscribes to. See [WebSocket API](/sdk/handlers-simple-api-websocket/) for the handler shape and authentication flow.
  - **Keep it mobile-first.** The companion runs on phones. System fonts, stacked sections, generous tap targets, no hover interactions — your app should feel native inside the companion's shell.
  - **Drop your own top chrome in patient and note scope.** The companion harness already renders the patient's name (and, in note scope, the note type and date) above your iframe. If your plugin also renders a title bar, the result is a doubled-up header. Suppress the iframe's header when running in patient or note scope — either branch in your Application and pass a hint through the launch URL, or scope the CSS on a body class your shell sets from the query string.
  - **Link out to another patient with`window.top.location`.** To navigate from inside your modal to another patient's companion view — for example, a "tap a patient name to jump there" pattern — set `window.top.location = "/companion/patient/<uuid>/"`. That tears down the iframe and replaces the parent page. Setting only the iframe's `location` leaves the modal open showing the patient page on top of whatever was behind it, which is rarely what you want.

# AttributeHubs

Source: https://docs.canvasmedical.com/sdk/custom-data-attribute-hubs/

##  Overview 
`AttributeHubs` provide a simple mechanism for storing arbitrary data that doesn't belong to existing models, or does not conform to a traditional database schema. An AttributeHub is merely a collection of named attributes with values. This approach is ideal for cross-cutting concerns that span multiple models, temporary data storage, external system state tracking, data model prototyping, or plugin-specific configuration.
**Best for:**
  - Cross-cutting state that spans multiple models (sync cursors, external IDs)
  - One-off or small-collection configuration and state
  - Data with no natural schema (varying fields per record)
  - External system state tracking
**Example use cases:**
  - API synchronization state
  - External system identifiers
  - Plugin configuration and feature flags
**Not ideal for** entities with relationships, large collections you need to search or paginate, or data requiring aggregation or reporting. See [Design Considerations](/sdk/custom-data-design-considerations/) for detailed guidance.
##  Creating an AttributeHub 
Create a hub for a specific purpose using the `type` and `id` fields, which together form a unique key. There is a database constraint on these two fields to ensure uniqueness, and creating a duplicate will raise a `UniqueViolation` exception.
    ```python
    from canvas_sdk.v1.data import AttributeHub
    # Create a hub for a specific purpose
    hub = AttributeHub.objects.create(
        type="staff_profile",
        id="staff_id:abc123"
    )
    ```
##  Storing Data in AttributeHub 
Store individual attributes or complex data as JSON. Here's an example of a meal tracker that records patient meals and calories:
    ```python
    from datetime import datetime
    from canvas_sdk.v1.data import AttributeHub, Patient
    patient = Patient.objects.get(id="patient-uuid-here")
    # Create a hub to track a specific meal
    hub = AttributeHub.objects.create(
        type="meal_entry",
        id=f"patient:{patient.id}:meal:{datetime.now().isoformat()}"
    )
    # Store individual attributes
    hub.set_attribute("meal_type", "lunch")
    hub.set_attribute("calories", 650)
    hub.set_attribute("recorded_at", datetime.now())
    # Store complex data as JSON
    meal_details = {
        "foods": [
            {"name": "Grilled chicken salad", "calories": 350, "protein_g": 35},
            {"name": "Whole grain roll", "calories": 150, "protein_g": 5},
            {"name": "Apple", "calories": 95, "protein_g": 0},
            {"name": "Water", "calories": 0, "protein_g": 0}
        ],
        "notes": "Patient reported feeling satisfied after meal"
    }
    hub.set_attribute("meal_details", meal_details)
    # Store multiple attributes at once
    hub.set_attributes({
        "total_protein_g": 40,
        "meal_location": "home",
        "logged_by": "patient_self_report"
    })
    ```
##  Retrieving Data from AttributeHub 
Use the get-or-create pattern to retrieve existing hubs or create new ones:
    ```python
    from canvas_sdk.v1.data import AttributeHub, Patient
    patient = Patient.objects.get(id="patient-uuid-here")
    # Get or create a hub for tracking daily calorie totals
    hub, created = AttributeHub.objects.get_or_create(
        type="daily_calorie_summary",
        id=f"patient:{patient.id}:date:2024-01-15"
    )
    if created:
        # Initialize a new day's tracking
        hub.set_attributes({
            "total_calories": 0,
            "meal_count": 0,
            "calorie_goal": 2000
        })
    # Retrieve attributes
    total_calories = hub.get_attribute("total_calories")
    meal_count = hub.get_attribute("meal_count")
    calorie_goal = hub.get_attribute("calorie_goal")
    # Handle missing attributes gracefully
    notes = hub.get_attribute("daily_notes")  # Returns None if not set
    ```
##  Supported Value Types 
Attributes are automatically stored in appropriately typed database columns. The column is selected based on the Python type of the value you pass to `set_attribute()`:
    ```python
    from datetime import date, datetime
    from canvas_sdk.v1.data import AttributeHub
    hub = AttributeHub.objects.get(type="staff_profile", id="staff_id:abc123")
    # String values
    hub.set_attribute("bio", "Board-certified cardiologist")
    # Integer values
    hub.set_attribute("patient_capacity", 100)
    # Boolean values
    hub.set_attribute("accepting_patients", True)
    # Decimal values
    hub.set_attribute("rating", 4.8)
    # Date values
    hub.set_attribute("creation_date", date.today())
    # Datetime values
    hub.set_attribute("last_updated", datetime.now())
    # JSON/Complex objects (dicts, lists)
    hub.set_attribute("preferences", {
        "notification_email": True,
        "notification_sms": False
    })
    ```
Field Name| Python Type| Django Field Type| PostgreSQL Data Type  
---|---|---|---  
`text_value`| `str`| `TextField`| `text`  
`int_value`| `int`| `IntegerField`| `integer`  
`bool_value`| `bool`| `BooleanField`| `boolean`  
`decimal_value`| `float`, `Decimal`| `DecimalField`| `decimal(20,10)`  
`date_value`| `date`| `DateField`| `date`  
`timestamp_value`| `datetime`| `DateTimeField`| `timestamp with time zone`  
`json_value`| `dict`, `list`| `JSONField`| `jsonb`  
These typed columns can be referenced directly in queries. See When to Use Explicit Field Names for cases where you need to target a specific column.
##  Querying AttributeHubs by Attribute Values 
Find AttributeHubs based on the values stored in their attributes using `custom_attributes__value`. The SDK automatically routes the filter to the correct typed column based on the Python type of the value you pass in:
    ```python
    from canvas_sdk.v1.data import AttributeHub
    # Find hubs with a specific string attribute
    lunch_hubs = AttributeHub.objects.filter(
        type="meal_entry",
        custom_attributes__name="meal_type",
        custom_attributes__value="lunch",
    )
    # Find hubs with a calorie count above a threshold
    high_calorie = AttributeHub.objects.filter(
        type="meal_entry",
        custom_attributes__name="calories",
        custom_attributes__value__gte=500,
    )
    # Find hubs with a boolean flag
    active_flags = AttributeHub.objects.filter(
        type="feature_flags",
        custom_attributes__name="enabled",
        custom_attributes__value=True,
    )
    ```
You can also filter attribute objects directly, for example when working with a hub's related attributes:
    ```python
    from canvas_sdk.v1.data import AttributeHub
    hub = AttributeHub.objects.get(type="meal_entry", id="patient:abc:meal:2024-01-15T12:00")
    # Filter the hub's own attributes
    high_cal_attrs = hub.custom_attributes.filter(value__gte=500)
    ```
###  When to Use Explicit Field Names 
In most cases `custom_attributes__value` (or `value` on a hub's related attributes) is sufficient. However, you must reference the typed column directly in the following cases:
  - **JSON containment queries.** PostgreSQL's `@>` containment operator on `jsonb` has different semantics from the `LIKE '%...%'` that `__contains` produces on a text column. Since `value__contains` with a string argument targets `text_value`, you must use `json_value__contains` to perform JSON containment checks:
        ```python
        from django.db.models import Q
        from canvas_sdk.v1.data import AttributeHub
        # Find hubs whose "specialties" JSON array contains "Cardiology"
        AttributeHub.objects.filter(
            type="staff_profile",
            custom_attributes__name="specialties",
            custom_attributes__json_value__contains="Cardiology",
        )
        # OR across multiple JSON values
        specialty_filters = Q()
        for specialty in ["Cardiology", "Internal Medicine"]:
            specialty_filters |= Q(custom_attributes__json_value__contains=specialty)
        AttributeHub.objects.filter(
            Q(custom_attributes__name="specialties") & specialty_filters
        )
        ```
  - **Custom JSON lookups.** Django's `JSONField` supports lookups like `__has_key`, `__contained_by`, and key-path access (`json_value__key__nested`). These are only available on the `json_value` column directly.
  - **Ambiguous Python types.** The `value` rewriter uses `type()` (not `isinstance()`) to select the column. If you pass a string but intend to query `json_value` (or vice versa), the rewriter will target the wrong column. Use the explicit field name when the Python type of your filter value doesn't match the storage column.
  - **Null checks across relations.** `custom_attributes__value=None` and `custom_attributes__value__isnull` are not supported on `AttributeHub.objects.filter(...)` and will raise `TypeError`. Null checks require testing every typed column, which produces unreliable results when combined with Django's cross-relation JOIN machinery. Use explicit column names instead:
        ```python
        from canvas_sdk.v1.data import AttributeHub
        # Check whether a specific column is null across the relation
        AttributeHub.objects.filter(
            type="staff_profile",
            custom_attributes__name="specialty",
            custom_attributes__text_value__isnull=True,
        )
        ```
Note that `value=None` and `value__isnull` _are_ supported for direct queries on a hub's own attributes (e.g., `hub.custom_attributes.filter(value__isnull=True)`), where no cross-relation join is involved.
Refer to Supported Value Types for the mapping between Python types and database columns.
##  Optimizing Queries with Prefetch 
By default, the AttributeHub manager prefetches all custom attributes when you query hubs. This means accessing `hub.get_attribute(...)` after a query does not trigger additional database queries:
    ```python
    from canvas_sdk.v1.data import AttributeHub
    # All custom attributes are prefetched automatically
    hubs = AttributeHub.objects.filter(type="meal_entry")
    for hub in hubs:
        # No additional queries — attributes are already loaded
        meal_type = hub.get_attribute("meal_type")
        calories = hub.get_attribute("calories")
    ```
###  Prefetching Specific Attributes 
When a hub has many attributes but you only need a few, use `with_only()` to prefetch only the attributes you need. This reduces the amount of data transferred from the database:
    ```python
    from canvas_sdk.v1.data import AttributeHub
    # Prefetch only the "calories" and "meal_type" attributes
    hubs = AttributeHub.objects.with_only(["calories", "meal_type"]).filter(type="meal_entry")
    for hub in hubs:
        calories = hub.get_attribute("calories")       # Loaded from prefetch cache
        meal_type = hub.get_attribute("meal_type")     # Loaded from prefetch cache
        notes = hub.get_attribute("notes")             # Falls back to a DB query (not prefetched)
    # Prefetch a single attribute
    hub = AttributeHub.objects.with_only("campaign_status").get(
        type="crm_sync", id="patient:abc123"
    )
    ```
If you access an attribute that was not included in `with_only()`, it will fall back to a database query. Use `with_only()` as an optimization, not a filter.
##  Use Case Example: CRM Campaign Sync 
Store synchronization state between a custom data model and an external CRM using AttributeHub:
    ```python
    from canvas_sdk.handlers.simple_api import SimpleAPI, api
    from canvas_sdk.effects.simple_api import JSONResponse
    from canvas_sdk.v1.data import AttributeHub, Patient
    from datetime import datetime
    class CRMSyncAPI(SimpleAPI):
        """API endpoint for syncing campaign data with external CRM."""
        PREFIX = "/crm"
        @api.post("/campaign/<campaign_id>/patient/<patient_id>")
        def sync_patient_campaign(self):
            campaign_id = self.request.path_params["campaign_id"]
            patient_id = self.request.path_params["patient_id"]
            patient = Patient.objects.get(id=patient_id)
            crm_data = self.request.json()
            # Store CRM sync state in AttributeHub
            hub, created = AttributeHub.objects.get_or_create(
                type="crm_campaign_sync",
                id=f"patient:{patient.id}:campaign:{campaign_id}"
            )
            hub.set_attributes({
                "crm_contact_id": crm_data.get("contact_id"),
                "campaign_status": crm_data.get("status"),
                "enrollment_date": crm_data.get("enrolled_at"),
                "last_synced": datetime.now(),
                "sync_direction": "crm_to_canvas"
            })
            return [JSONResponse({"status": "success", "hub_id": str(hub.id)})]
    ```
Later, retrieve the sync state when processing patient events:
    ```python
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.v1.data import AttributeHub
    class CampaignEnrollmentHandler(BaseHandler):
        """Handler that checks CRM campaign sync state for patients."""
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self):
            patient_id = self.target.id
            campaign_id = "wellness_2024"  # Your campaign identifier
            # Retrieve CRM sync state from AttributeHub
            hub, created = AttributeHub.objects.get_or_create(
                type="crm_campaign_sync",
                id=f"patient:{patient_id}:campaign:{campaign_id}"
            )
            if not created:
                crm_contact_id = hub.get_attribute("crm_contact_id")
                campaign_status = hub.get_attribute("campaign_status")
                last_synced = hub.get_attribute("last_synced")
                # Use the CRM data to drive clinical workflows
                if campaign_status == "enrolled":
                    # Patient is enrolled in CRM campaign - trigger relevant protocols
                    pass
            return []
    ```
##  Best Practices 
###  Data Organization 
  1. **Use descriptive type values** \- Choose meaningful type names that describe the purpose of the hub (e.g., "external_sync", "api_cache", "feature_flags")
  2. **Use consistent ID patterns** \- Use a consistent pattern for `id` (e.g., "entity_type:entity_id")
  3. **Namespace by purpose** \- Group related data under a single hub rather than creating multiple hubs for the same entity type
###  Data Privacy and Isolation 
  1. **Understand plugin data scoping** \- All AttributeHub data is isolated to your plugin's namespace
  2. **Implement proper authorization** \- Secure all APIs that expose AttributeHub data
  3. **Follow PHI guidelines** \- Treat all patient-related data with appropriate security measures
###  Performance 
  1. **Batch attribute updates** \- Use `set_attributes()` to set multiple values at once
  2. **Cache hub lookups** \- If accessing the same hub multiple times, store the reference
###  Data Integrity 
  1. **Use get_or_create** \- Use `get_or_create()` to avoid duplicate hubs
  2. **Handle None values** \- Always check if an attribute exists before using it
  3. **Validate data** \- Validate data before storing in AttributeHub
  4. **Clean up unused data** \- Remove AttributeHub instances that are no longer needed
###  Testing 
  1. **Use get_or_create in tests** \- This pattern works well for test isolation
  2. **Isolate test data** \- Create all data required by the test, within the test

# CustomModels

Source: https://docs.canvasmedical.com/sdk/custom-data-custom-models/

##  Overview 
CustomModels allow you to define fully structured, typed data models with relationships among entities and normalized data. Built on Django's ORM, CustomModels provide the most powerful and flexible approach to storing custom data in Canvas plugins.
The functionality expressed is a subset of the total ORM. The SDK omits some features in order to simplify the lifecycle of plugin installation and maintenance.
**Best for:**
  - Structured data with a stable, known schema
  - Relationships between entities (foreign keys, join tables)
  - Data requiring compound filtering, sorting, or aggregation
  - Data consumed by reports or analytics
**Example use cases:**
  - Provider specialties and certifications
  - Constructing new associations among Canvas SDK models
  - Custom workflows and forms
  - Integration-specific data structures
  - Practice-specific business entities
**Not ideal for** simple metadata on existing models, highly variable or schemaless data, or ephemeral data. Tables and columns cannot be dropped once created. See [Design Considerations](/sdk/custom-data-design-considerations/) for detailed guidance.
Custom models may be associated to core SDK data models by extending them with `ModelExtension`, or may be entirely standalone. As an example, a `StaffBiography` CustomModel could attach to a `CustomStaff(Staff, ModelExtension)` class, and be accessible via a `biography` property on `CustomStaff`.
Custom models must be defined within a `models` directory under the plugin top-level directory. E.g., `/my_plugin/models/custom_model_a.py`. If not, then database migrations will not be applied. (Extended SDK models may be defined anywhere since they do not require any database modifications.)
* * *
##  Basic CustomModel 
Create a custom model by extending `CustomModel`:
    ```python
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import BooleanField, DateField, DateTimeField, DecimalField, IntegerField, JSONField, TextField
    class HealthCoach(CustomModel):
        name = TextField()
        practicing_since = IntegerField()
        version = DecimalField(default=1.0, decimal_places=1, max_digits=3)
        is_accepting_patients = BooleanField()
        created_date = DateField(auto_now_add=True)
        last_modified_at = DateTimeField(auto_now_add=True)
        extended_attributes = JSONField()
    ```
This above definition will result in a PostgreSQL table named `healthcoach`. It will have a primary key column named `dbid` of type `serial`, an auto-incrementing integer. It will have six additional columns of `text`, `integer`, `numeric(3,8)`, `boolean`, `jsonb`,`date`, and `timestamp with time zone`, respectively.
* * *
##  Schema Rules and Constraints 
To maintain safety on potentially large datasets, most constraints on CustomModels are not enforced within the database and must be enforced within plugin code.
Unsupported constraints:
  - `not null`
  - `max_length`
  - `references` (database-level foreign key constraints)
If applied to an existing dataset, these constraints could result in a full table rewrite operation, or prevent plugin installation. Note that while database-level `REFERENCES` constraints are not created, Django's ORM enforces `on_delete` behavior (`CASCADE`, `SET_NULL`, `DO_NOTHING`) at the application level — see Delete Behavior below.
Uniqueness constraints **are** supported via `UniqueConstraint` in `Meta.constraints`. See Uniqueness Constraints below.
###  Field Types 
The Canvas SDK provides Django-based field types for defining your models:
Field Type| Description| Supported Parameters  
---|---|---  
`TextField`| Variable-length text| `default`  
`IntegerField`| Integer values| `default`  
`DecimalField`| Decimal numbers| `default`, `max_digits`,`decimal_places`  
`BooleanField`| True/False values| `default`  
`DateField`| Date values| `auto_now`, `auto_now_add`, `default`  
`DateTimeField`| Date and time values| `auto_now`, `auto_now_add`, `default`  
`JSONField`| JSON-serializable data| `default`  
`ForeignKey`| Many-to-one relationship| `related_name`, `on_delete`, `to_field`  
`OneToOneField`| One-to-one relationship| `related_name`, `on_delete`, `to_field`, `primary_key`  
`ManyToManyField`| Many-to-many relationship| `through` (required), `related_name`  
If `default` is supplied it will be applied by the Django ORM, and will not be a PostgreSQL default. As a result, only new records will receive the value, and it will not cause a mass edit of existing records.
The `on_delete` parameter is required on `ForeignKey` and `OneToOneField`. It controls what happens to child records when the referenced parent record is deleted:
Value| Behavior  
---|---  
`CASCADE`| Automatically delete the child record when the parent is deleted.  
`SET_NULL`| Set the foreign key column to `NULL` when the parent is deleted. The child record is kept.  
`DO_NOTHING`| Take no action. The plugin is responsible for cleaning up or preventing orphaned references.  
These behaviors are enforced by Django's ORM at the application level. They apply when deleting via `model.delete()` or `queryset.delete()`, but not when using raw SQL.
###  Indexes 
Add indexes for frequently queried fields:
    ```python
    from canvas_sdk.v1.data.base import CustomModel
    from django.contrib.postgres.indexes import GinIndex
    from django.db.models import BooleanField, DateTimeField, Index, IntegerField, JSONField, TextField
    class ProviderQualification(CustomModel):
        first_name = TextField()
        last_name = TextField()
        board_certified = BooleanField()
        practicing_since_year = IntegerField()
        extended_attributes = JSONField()
        created_at = DateTimeField()
        class Meta:
            indexes = [
                # Single-column index
                Index(fields=["practicing_since_year"]),
                # Composite index for common search combinations
                Index(fields=["first_name", "last_name"]),
                # Descending index for ordering records
                Index(fields=["-created_at"]),
                # Gin index for efficient JSON queries
                GinIndex(fields=["extended_attributes"])
            ]
    ```
**Index Best Practices:**
  - Index fields used in `filter()` and `order_by()`
  - Create composite indexes for common multi-field queries
  - **Do not** index `ForeignKey` or `OneToOneField` columns — they are indexed automatically. The SDK will raise an error if you declare a single-column index that duplicates an auto-indexed column.
###  Uniqueness Constraints 
Use `UniqueConstraint` in `Meta.constraints` to enforce uniqueness on one or more columns. Uniqueness is enforced at the database level via a `CREATE UNIQUE INDEX`.
    ```python
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import TextField, UniqueConstraint
    class Specialty(CustomModel):
        name = TextField()
        code = TextField()
        class Meta:
            constraints = [
                UniqueConstraint(fields=["code"], name="uq_specialty_code"),
            ]
    ```
Composite uniqueness (multiple columns together must be unique):
    ```python
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import DO_NOTHING, ForeignKey, TextField, UniqueConstraint
    from canvas_sdk.v1.data import Staff, ModelExtension
    class CustomStaff(Staff, ModelExtension):
        pass
    class StaffCertification(CustomModel):
        staff = ForeignKey(CustomStaff, to_field="dbid", on_delete=DO_NOTHING, related_name="%(app_label)s__certifications")
        certification_code = TextField()
        class Meta:
            constraints = [
                UniqueConstraint(fields=["staff", "certification_code"], name="uq_staff_cert"),
            ]
    ```
Each `UniqueConstraint` requires a `name` parameter — this is a standard Django requirement. Choose a descriptive name that won't collide with other constraints in your plugin.
Use Django field names (e.g., `"staff"`) rather than database column names (e.g., `"staff_id"`) in the `fields` list — the SDK resolves field names to column names automatically. The same applies to `Index` fields in `Meta.indexes`.
**Important:** Do not use `unique=True` on individual fields. The SDK will reject it with an error directing you to use `UniqueConstraint` instead. This is because `unique=True` modifies the column definition itself, and our DDL pipeline cannot retroactively alter existing columns — meaning a `unique=True` added after the initial deployment would silently have no effect.
**Constraint placement:** `UniqueConstraint` must be placed in `Meta.constraints`, not `Meta.indexes`. Although they are structurally similar to indexes, placing a `UniqueConstraint` in `Meta.indexes` would create a non-unique index. The SDK validates this and raises an error if it detects the mistake.
**Lifecycle:** Unique indexes are created with `CREATE UNIQUE INDEX IF NOT EXISTS`, making them safe to add at any time — they are applied idempotently on every deployment. However, if the table already contains duplicate values for the constrained columns, the index creation will fail. Clean up duplicates before adding the constraint.
Operation| Allowed| Explanation  
---|---|---  
Add UniqueConstraint| Yes| A unique index will be created if it does not already exist.  
Remove UniqueConstraint| No| Remove the constraint from your model and it will be ignored, but the index will remain in the database.

##  Creating and Querying 
###  Creating Records 
    ```python
    from my_plugin.models import ProviderQualification
    # Create and save
    qualification = ProviderQualification(
        first_name="Jessica",
        last_name="Smith",
        board_certified=True,
        practicing_since_year=2005,
        extended_attributes={ "biography": "Lives in Fresno with her..." }
    )
    qualification.save()
    # Create in one step
    qualification = ProviderQualification.objects.create(

            "extended_attributes": { "biography": "Lives in Fresno with her..." }
        }
    )
    ```
###  Querying Records 
    ```python
    from my_plugin.models import ProviderQualification
    from datetime import date
    # Get all records
    all_qualifications = ProviderQualification.objects.all()
    # Filter records
    board_certified = ProviderQualification.objects.filter(board_certified=True)
    # Get providers with 10+ years experience
    experienced = ProviderQualification.objects.filter(
        practicing_since_year__lte=date.today().year - 10
    )
    # Get single record by database primary key
    try:
        jessica = ProviderQualification.objects.get(dbid=123)
    except ProviderQualification.DoesNotExist:
        jessica = None
    # Get single record by fields
    try:
        jessica = ProviderQualification.objects.get(first_name="Jessica", last_name="Smith")
    except ProviderQualification.DoesNotExist:
        jessica = None
    # Apply multiple filters
    senior_certified = ProviderQualification.objects.filter(
        board_certified=True,
        practicing_since_year__lte=2010  # Practicing since 2010 or earlier
    )
    # Order results

    # Delete single record
    qualification = ProviderQualification.objects.get(first_name="Jessica", last_name="Smith")
    qualification.delete()
    # Delete multiple records - remove providers who started this year
    from datetime import date
    ProviderQualification.objects.filter(
        practicing_since_year=date.today().year
    ).delete()
    # Delete all records (use with caution!)
    ProviderQualification.objects.all().delete()
    ```
##  Extending the Canvas Data Model 
CustomModels may reference core SDK models by creating a proxy model with `ModelExtension`. This gives each plugin its own private handle on a shared SDK model, keeping `related_name` attributes isolated across plugins.
    ```python
    from canvas_sdk.v1.data import Staff, ModelExtension
    class CustomStaff(Staff, ModelExtension):
        pass
    ```
No new table is created — `CustomStaff` shares the `Staff` table and behaves identically for queries. Point your `ForeignKey` or `OneToOneField` at the proxy to get clean, un-namespaced reverse lookups.
For a full explanation of why proxy models exist, how `related_name` namespacing works, and how to reference SDK models directly without a proxy, see [Extending SDK Models](/sdk/custom-data-extending-sdk-models/).
* * *
##  One-to-One Relationships 
A one-to-one relationship links one record in a model to exactly one record in another model. Use `OneToOneField` to define this relationship.
###  Basic One-to-One 
    ```python
    from canvas_sdk.v1.data import Staff, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import CASCADE, DateTimeField, DecimalField, OneToOneField, TextField
    class CustomStaff(Staff, ModelExtension):
        """Extends Staff with custom attribute support."""
        pass
    class Biography(CustomModel):
        biography = TextField()
        language = TextField()
        version = DecimalField(default=1.0, decimal_places=1, max_digits=3)
        last_modified_at = DateTimeField(auto_now_add=True)
        staff = OneToOneField(
            CustomStaff, to_field="dbid", on_delete=CASCADE, related_name="biography"
        )
    ```
The above will create a table with a `serial` primary key, two `text` columns, a `numeric(1,3)` column, a `timestamptz` column, and an `integer` column named `staff_id` that contains a foreign key into the SDK `Staff` model. The `CustomStaff` class will contain the reverse mapping via `related_name`.
**Uniqueness:** A `OneToOneField` implies that the foreign key column is unique — each target record can be referenced by at most one row. The SDK automatically creates a `UNIQUE INDEX` on the foreign key column to enforce this at the database level. Do not add a separate `UniqueConstraint` for it — the SDK will raise an error if you declare a single-column `UniqueConstraint` or `Index` on an auto-indexed column.
###  One-to-One with `primary_key=True`
A `OneToOneField` can serve as the table's primary key by setting `primary_key=True`. This replaces the default auto-incrementing `dbid` column — the foreign key column becomes the sole primary key.
This pattern is useful when the child record has a strict 1:1 relationship with its parent and there is no need for a separate surrogate key.
    ```python
    from canvas_sdk.v1.data import Patient, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import CASCADE, JSONField, OneToOneField
    class CustomPatient(Patient, ModelExtension):
        pass
    class PatientPreferences(CustomModel):
        patient = OneToOneField(
            CustomPatient, to_field="dbid", on_delete=CASCADE,
            related_name="preferences", primary_key=True
        )
        preferences = JSONField(default=dict)
    ```
The above will create a table with a single `integer` primary key column `patient_id` (no `dbid` column) and a `jsonb` column. The primary key inherently enforces uniqueness, so no additional unique index is created.
**Note:** `primary_key=True` is only supported on `OneToOneField`. Setting it on a `ForeignKey` or any other field type will raise an error — use a `OneToOneField` instead when you need a shared primary key.
###  Creating One-to-One Records 
    ```python
    from my_plugin.models import CustomStaff, Biography
    # Get the staff member
    staff = CustomStaff.objects.get(id="staff-uuid")
    # Create biography
    biography = Biography.objects.create(
        staff=staff,
        biography="Dr. Smith is a board-certified cardiologist with over 20 years of experience...",
        language="English",
        version=1.0
    )
    ```
###  Querying One-to-One Relationships 
    ```python
    from my_plugin.models import CustomStaff, Biography
    # Access from biography to staff
    biography = Biography.objects.get(dbid=1)
    staff_member = biography.staff
    # Access from staff to biography (using related_name)
    staff = CustomStaff.objects.get(id="staff-uuid")
    try:
        bio = staff.biography
    except Biography.DoesNotExist:
        print("No biography found")
    # Find all staff with biographies in Spanish
    spanish_providers = CustomStaff.objects.filter(
        biography__language="Spanish"
    )
    # Find staff whose biography was last updated before a certain date
    from datetime import datetime, timedelta
    outdated_bios = CustomStaff.objects.filter(
        biography__last_modified_at__lte=datetime.now() - timedelta(days=365)
    )
    ```
* * *
##  One-to-Many Relationships 
A one-to-many (or many-to-one) relationship allows one record to be associated with multiple records in another model. Use `ForeignKey` to define this relationship.
###  Basic One-to-Many 
    ```python
    from canvas_sdk.v1.data import Staff, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import CASCADE, DateTimeField, DecimalField, ForeignKey, TextField
    class CustomStaff(Staff, ModelExtension):
      """Extends Staff with custom attribute support."""
      pass
    class Biography(CustomModel):
      biography = TextField()
      language = TextField()
      version = DecimalField(default=1.0, decimal_places=1, max_digits=3)
      last_modified_at = DateTimeField(auto_now_add=True)
      # Same as one-to-one, but a Foreign key with a plural 'related_name'. Now, each staff may have multiple biographies,
      # perhaps in different languages.
      staff = ForeignKey(
        CustomStaff, to_field="dbid", on_delete=CASCADE, related_name="biographies"
      )
    ```
###  Creating One-to-Many Records 
    ```python
    from my_plugin.models import CustomStaff, Biography
    # Get staff member
    staff = CustomStaff.objects.get(id="staff-uuid")
    # Create multiple biographies for one provider (e.g., in different languages)
    english_bio = Biography.objects.create(
        staff=staff,
        biography="Dr. Smith is a board-certified cardiologist with over 20 years of experience in interventional cardiology.",
        language="English",
        version=1.0
    )
    spanish_bio = Biography.objects.create(
        staff=staff,
        biography="La Dra. Smith es una cardióloga certificada con más de 20 años de experiencia en cardiología intervencionista.",
        language="Spanish",
        version=1.0
    )
    ```
###  Querying One-to-Many Relationships 
    ```python
    from my_plugin.models import CustomStaff, Biography
    # Access from biography to staff (forward)
    biography = Biography.objects.get(language="Spanish")
    provider = biography.staff
    print(f"Provider: {provider.first_name} {provider.last_name}")
    # Access from staff to biographies (reverse, using related_name)
    staff = CustomStaff.objects.get(id="staff-uuid")
    biographies = staff.biographies.all()
    for bio in biographies:
        print(f"- {bio.language}: {bio.biography[:50]}... (v{bio.version})")
    # Filter reverse relationship
    english_bios = staff.biographies.filter(language="English")
    # Query across relationship
    # Find all staff who have biographies in Spanish
    spanish_speaking_providers = CustomStaff.objects.filter(
        biographies__language="Spanish"
    )
    # Find staff with multiple biography versions
    from django.db.models import Count
    providers_with_multiple_bios = CustomStaff.objects.annotate(
        bio_count=Count('biographies')
    ).filter(bio_count__gt=1)
    # Count related records
    biography_count = staff.biographies.count()
    # Check existence
    has_spanish_bio = staff.biographies.filter(language="Spanish").exists()
    ```
* * *
##  Many-to-Many Relationships 
A many-to-many relationship allows multiple records in one model to be associated with multiple records in another model.
Many-to-many relationships require an **explicit through model** — a CustomModel that contains ForeignKey fields to both sides of the relationship. Standard Django allows `ManyToManyField` to create an implicit join table automatically, but the Canvas SDK does not support implicit through tables because each table must be a CustomModel with a managed schema lifecycle.
You can define the relationship in two ways:
  1. **Through model only** — Define the through model with ForeignKeys and query through it directly.
  2. **Through model +`ManyToManyField`** — Add a `ManyToManyField` with an explicit `through` parameter for cleaner ORM access.
Both approaches create the same database tables. The `ManyToManyField` adds ORM convenience (e.g., `specialty.staff.all()` instead of traversing the join table manually) but does not change the underlying schema.
###  Through Model Only 
The simplest approach is to define just the through model. This works well when the through model has additional metadata fields or when you prefer to query the join table directly.
    ```python
    from django.db.models import CASCADE, ForeignKey, Index, TextField, UniqueConstraint
    from canvas_sdk.v1.data.base import CustomModel
    from canvas_sdk.v1.data import Staff, ModelExtension
    class CustomStaff(Staff, ModelExtension):
      """Extends Staff with custom attribute support."""
      pass
    class Specialty(CustomModel):
      """Medical specialty (e.g., Cardiology, Neurology)."""
      name = TextField()
      class Meta:
        indexes = [
          Index(fields=["name"]),
        ]
    # Declaring this class will result in a join table called `staffspecialty`
    class StaffSpecialty(CustomModel):
      """Many-to-many relationship: Staff can have many specialties, specialties can have many staff."""
      staff = ForeignKey(
        CustomStaff,
        to_field="dbid",
        on_delete=CASCADE,
        related_name="staff_specialties"
      )
      specialty = ForeignKey(
        Specialty,
        to_field="dbid",
        on_delete=CASCADE,
        related_name="staff_specialties"
      )
      class Meta:
        constraints = [
          UniqueConstraint(
            fields=["staff", "specialty"],
            name="unique_staff_specialty",
          ),
        ]
    ```
This creates a many-to-many relationship where:
  - One staff member can have multiple specialties
  - One specialty can be assigned to multiple staff members
  - `StaffSpecialty` is the through model that connects them
**Preventing duplicate associations:** Through models typically need a uniqueness constraint on the pair of foreign key columns to prevent the same association from being created twice. Add a `UniqueConstraint` to the through model's `Meta.constraints` referencing both FK field names (e.g., `staff` and `specialty`). Without this, calling `StaffSpecialty.objects.create(staff=staff, specialty=cardiology)` twice would create two identical rows. See Uniqueness Constraints for more details on constraint naming and lifecycle.
###  Through Model + ManyToManyField 
Adding a `ManyToManyField` with an explicit `through` parameter gives you direct ORM access to the related objects without manually traversing the join table.
**Important:** The `through` parameter is **required**. A `ManyToManyField` without `through` will cause an error because the SDK cannot manage implicit join tables.
    ```python
    from django.db.models import CASCADE, ForeignKey, Index, ManyToManyField, TextField, UniqueConstraint
    from canvas_sdk.v1.data.base import CustomModel
    from canvas_sdk.v1.data import Staff, ModelExtension
    class CustomStaff(Staff, ModelExtension):
      """Extends Staff with custom attribute support."""
      pass
    class Specialty(CustomModel):
      """Medical specialty (e.g., Cardiology, Neurology)."""
      name = TextField()
      staff = ManyToManyField(
        CustomStaff,
        through="StaffSpecialty",
        related_name="%(app_label)s_specialties",
      )
      class Meta:
        indexes = [
          Index(fields=["name"]),
        ]
    class StaffSpecialty(CustomModel):
      """Through model for the staff-specialty relationship."""
      staff = ForeignKey(
        CustomStaff,
        to_field="dbid",
        on_delete=CASCADE,
        related_name="%(app_label)s_staff_specialties",
      )
      specialty = ForeignKey(
        Specialty,
        to_field="dbid",
        on_delete=CASCADE,
        related_name="staff_specialties",
      )
      class Meta:
        constraints = [
          UniqueConstraint(
            fields=["staff", "specialty"],
            name="unique_staff_specialty",
          ),
        ]
    ```
With the `ManyToManyField` declared, you can traverse the relationship directly:
    ```python
    # Direct access to related objects (returns Staff queryset, not StaffSpecialty)
    specialty = Specialty.objects.get(name="Cardiology")
    staff_members = specialty.staff.all()
    # Reverse access from staff to specialties
    staff = CustomStaff.objects.get(id="staff-uuid")
    specialties = staff.staff_plus_specialties.all()  # uses the ManyToManyField's related_name
    ```
Compare this with the through-model-only approach, where you must navigate through the join table:
    ```python
    # Without ManyToManyField — must traverse the join table
    staff_members = [ss.staff for ss in specialty.staff_specialties.all()]
    ```
####  Differences from Standard Django ManyToManyField 
Behavior| Standard Django| Canvas SDK  
---|---|---  
`through` parameter| Optional — Django creates an implicit join table| **Required** — must reference a CustomModel  
`.add()`, `.remove()`, `.set()`| Available when no explicit through model| **Not available** — use the through model's `.objects.create()` and `.delete()` instead  
`.clear()`| Available| **Not available** — use `StaffSpecialty.objects.filter(...).delete()` instead  
`.all()`, filtering, `prefetch_related`| Available| Available  
Because Django requires you to use the through model directly for creating and deleting relationships when an explicit `through` is declared, the CRUD patterns are the same whether or not you add the `ManyToManyField`. The field's value is in query convenience — direct `.all()` access and cleaner `prefetch_related` lookups.
####  related_name with ManyToManyField 
When a `ManyToManyField` targets a core SDK model (like `Staff` or `Patient`), you **must** use the `%(app_label)s_` prefix in `related_name` to avoid naming collisions between plugins:
    ```python
    staff = ManyToManyField(
        CustomStaff,
        through="StaffSpecialty",
        related_name="%(app_label)s_specialties",  # becomes e.g. "my_plugin_specialties"
    )
    ```
This is the same namespacing requirement that applies to `ForeignKey` and `OneToOneField` when targeting SDK models. See [Extending SDK Models](/sdk/custom-data-extending-sdk-models/) for a full explanation of when namespacing is required and how proxy models avoid it.
###  Creating Many-to-Many Records 
Regardless of whether you use `ManyToManyField`, create and delete relationships through the through model directly:
    ```python
    from my_plugin.models import CustomStaff, Specialty, StaffSpecialty
    # Create specialties
    cardiology = Specialty.objects.create(name="Cardiology")
    internal_medicine = Specialty.objects.create(name="Internal Medicine")
    emergency_medicine = Specialty.objects.create(name="Emergency Medicine")
    # Get staff member
    staff = CustomStaff.objects.get(id="staff-uuid")
    # Create associations between staff and specialties
    StaffSpecialty.objects.create(staff=staff, specialty=cardiology)
    StaffSpecialty.objects.create(staff=staff, specialty=internal_medicine)
    # Bulk create multiple associations at once
    specialties_to_add = [emergency_medicine, cardiology]
    staff_specialties = [
        StaffSpecialty(staff=staff, specialty=specialty) for specialty in specialties_to_add
    ]
    StaffSpecialty.objects.bulk_create(staff_specialties)
    # Replace all specialties for a staff member
    # First, remove existing associations
    StaffSpecialty.objects.filter(staff=staff).delete()
    # Then create new associations
    new_specialties = [cardiology, emergency_medicine]
    new_staff_specialties = [
        StaffSpecialty(staff=staff, specialty=specialty) for specialty in new_specialties
    ]
    StaffSpecialty.objects.bulk_create(new_staff_specialties)
    ```
**Note:** Do not use `.add()`, `.remove()`, `.set()`, or `.clear()` on the `ManyToManyField`. Django disables these methods when an explicit `through` model is declared. Use the through model's manager (e.g., `StaffSpecialty.objects`) for all create and delete operations.
###  Querying Many-to-Many Relationships 
    ```python
    from my_plugin.models import CustomStaff, Specialty, StaffSpecialty
    # Access staff member's specialties through the join table
    staff = CustomStaff.objects.get(id="staff-uuid")
    staff_specialty_records = staff.staff_specialties.all()
    for staff_specialty in staff_specialty_records:
        print(f"- {staff_specialty.specialty.name}")
    # Get just the specialty names
    specialty_names = [ss.specialty.name for ss in staff.staff_specialties.all()]
    # Access all staff members with a specific specialty (reverse)
    cardiology = Specialty.objects.get(name="Cardiology")
    cardiology_staff_records = cardiology.staff_specialties.all()
    for staff_specialty in cardiology_staff_records:
        staff_member = staff_specialty.staff
        print(f"- {staff_member.first_name} {staff_member.last_name}")
    # Find staff IDs with specific specialties
    staff_ids = StaffSpecialty.objects.filter(
        specialty__name__in=["Cardiology", "Internal Medicine"]
    ).values_list("staff_id", flat=True)
    # Find staff members with a specific specialty
    cardiologists = CustomStaff.objects.filter(
        staff_specialties__specialty__name="Cardiology"
    ).distinct()
    # Check if a staff member has a specific specialty
    has_cardiology = staff.staff_specialties.filter(specialty__name="Cardiology").exists()
    # Count specialties for a staff member
    specialty_count = staff.staff_specialties.count()
    # Efficient querying with prefetch_related
    staff_with_specialties = (
        CustomStaff.objects
        .prefetch_related("staff_specialties__specialty")
        .all()
    )
    for staff in staff_with_specialties:
        specialties = [ss.specialty.name for ss in staff.staff_specialties.all()]
        print(f"{staff.first_name} {staff.last_name}: {', '.join(specialties)}")
    ```
**Key points about many-to-many relationships:**
  - Both sides of the relationship can access the through model using `related_name`
  - Without `ManyToManyField`: `staff.staff_specialties.all()` returns `StaffSpecialty` objects — access the related object via `ss.specialty`
  - With `ManyToManyField`: `specialty.staff.all()` returns `Staff` objects directly
  - You can add additional fields to the through model to store metadata about the relationship (e.g., date assigned, certification level, etc.)
  - Query across the relationship using double underscores: `CustomStaff.objects.filter(staff_specialties__specialty__name="Cardiology")`

The `on_delete` parameter on `ForeignKey` and `OneToOneField` controls what happens to child records when a parent record is deleted. The SDK supports three values:
  - **`CASCADE`** — Delete the child record automatically. This is the most common choice for tightly-coupled relationships like join table entries, child records that have no meaning without their parent, or `OneToOneField` with `primary_key=True`.
  - **`SET_NULL`** — Set the foreign key column to `NULL`, keeping the child record. Useful when the child has independent value even if its parent is removed (e.g., an audit log entry whose associated staff member has been deactivated).
  - **`DO_NOTHING`** — Take no automatic action. The plugin is fully responsible for preventing orphaned references.
These behaviors are enforced at the Django ORM level, not by database-level foreign key constraints. They apply when deleting via `model.delete()` or `queryset.delete()`.
**Tip:** Use `CASCADE` on through-model (join table) foreign keys so that deleting either side of a many-to-many relationship automatically cleans up the association rows.
##  The CustomModel Lifecycle 
Managing database schemas necessarily introduces complexity, because there is state to maintain over time as the software evolves. Common pitfalls include expensive table rewrite operations, migrations that fail in some environments due to manual changes, database system-specific nuances, unsatisfied foreign key constraints due to data corruption or improper order of operations, etc.
The Canvas SDK Custom Data feature aims to simplify maintenance, while sacrificing some rigor found in a full migration system like Django's.
Operation| Allowed| Explanation  
---|---|---  
Create Model| Yes| A table corresponding to your CustomModel will be created if it does not exist. An autoincrementing column named `dbid` will be its sole attribute.  
Add Field| Yes| A column corresponding to a Field declared within your CustomModel will be added to the table if it does not exist. It will be nullable, without defaults to eliminate table rewrites.  
Add UniqueConstraint| Yes| A unique index will be created if it does not already exist. Fails if existing data contains duplicates for the constrained columns.  
Add Index| Yes| An index will be created if it does not already exist.  
Alter Field| No| This can cause a table rewrite, and requires a full migration metadata system. Create a new Field in your model. Copy data from old to new.  
Drop Field| No| This will cause a table rewrite, and requires a full migration metadata system. Remove the Field from your model and it will be ignored.  
Drop UniqueConstraint| No| Remove the constraint from your model and it will be ignored, but the unique index will remain in the database.  
Drop Index| No| Remove the index from your model and it will be ignored, but the index will remain in the database.  
Alter Model| No| Requires a full migration metadata system. Create a new Model in your plugin. Copy data from old to new.  
Drop Model| No| Requires a full migration metadata system. Remove the model from your plugin and it will be ignored.  
###  Best Practices 
  1. Emphasize local development over use of a development EMR instance.
  2. Write [automated tests](/sdk/custom-data-testing/) exercising your business logic.
  3. Extract business logic and CRUD operations into "service" classes that can be tested in isolation.
##  Advanced Patterns 
###  Combining Approaches 
You can combine CustomModels with [AttributeHubs](/sdk/custom-data-attribute-hubs/) for maximum flexibility:
    ```python
    from canvas_sdk.v1.data.base import CustomModel
    from canvas_sdk.v1.data import AttributeHub, Staff, ModelExtension
    from django.db.models import CASCADE, ForeignKey, SET_NULL, TextField
    class CustomStaff(Staff, ModelExtension):
        pass
    class Department(CustomModel):
        """Structured department model."""
        name = TextField()
        code = TextField()
    class StaffDepartment(CustomModel):
        """Staff can belong to multiple departments."""
        staff = ForeignKey(
            CustomStaff, on_delete=SET_NULL, related_name="department_assignments"
        )
        department = ForeignKey(
            Department, on_delete=CASCADE, related_name="staff_members"
        )
        role = TextField()
    # Use CustomModels for structured data with relationships
    staff = CustomStaff.objects.get(id="staff-uuid")
    dept = Department.objects.get(code="CARDIO")
    StaffDepartment.objects.create(
        staff=staff,
        department=dept,
        role="Lead Physician"
    )
    # Use an AttributeHub for flexible, unstructured data
    hub, created = AttributeHub.objects.get_or_create(
        type="staff_preferences",
        id=f"staff:{staff.id}"
    )
    hub.set_attributes({
        "pager_number": "555-1234",
        "preferred_contact": "email",
        "office_hours": {"monday": "9-5", "tuesday": "9-5"}
    })
    ```
###  Query Optimization 
Optimize database queries using `select_related` and `prefetch_related`:
    ```python
    from my_plugin.models import Specialty, StaffSpecialty, CustomStaff
    # Use select_related for ForeignKey (SQL JOIN)
    # Load StaffSpecialty with related staff and specialty in one query
    staff_specialties = StaffSpecialty.objects.select_related("staff", "specialty").all()
    for ss in staff_specialties:
        # No additional queries - both staff and specialty are already loaded
        print(f"{ss.staff.first_name} {ss.staff.last_name}: {ss.specialty.name}")
    # Use prefetch_related for reverse ForeignKey relationships
    # Load staff with all their specialties efficiently
    staff_list = CustomStaff.objects.prefetch_related("staff_specialties__specialty").all()
    for staff in staff_list:
        # No additional queries - staff_specialties and specialties are already loaded
        for ss in staff.staff_specialties.all():
            print(f"{staff.first_name}: {ss.specialty.name}")
    # Prefetch specialties for multiple staff members
    specialties_list = Specialty.objects.prefetch_related("staff_specialties__staff").all()
    for specialty in specialties_list:
        staff_members = [ss.staff for ss in specialty.staff_specialties.all()]
        print(f"{specialty.name}: {len(staff_members)} staff members")
    # Use Prefetch for custom filtering
    from django.db.models import Prefetch
    # Only load staff specialties with specific specialty names
    staff_with_filtered_specialties = CustomStaff.objects.prefetch_related(
        Prefetch(
            "staff_specialties",
            queryset=StaffSpecialty.objects.filter(
                specialty__name__in=["Cardiology", "Neurology"]
            ).select_related("specialty")
        )
    ).all()
    ```
###  Complex Queries 
Use Django's Q objects for complex filtering and aggregation:
    ```python
    from django.db.models import Q, Count
    from my_plugin.models import CustomStaff, Specialty, StaffSpecialty
    # OR conditions - Find staff with Cardiology OR Neurology specialty
    staff_with_cardio_or_neuro = CustomStaff.objects.filter(
        Q(staff_specialties__specialty__name="Cardiology") |
        Q(staff_specialties__specialty__name="Neurology")
    ).distinct()
    # AND conditions - Find specialties with "Cardiology" or "Medicine" in the name
    cardio_or_medicine = Specialty.objects.filter(
        Q(name__icontains="Cardiology") | Q(name__icontains="Medicine")
    )
    # Negation - Find staff WITHOUT a specific specialty
    staff_without_cardiology = CustomStaff.objects.exclude(
        staff_specialties__specialty__name="Cardiology"
    )
    # Complex filtering - Staff with multiple specific specialties
    # Note: This requires DISTINCT because joins can create duplicate rows
    staff_with_multiple = CustomStaff.objects.filter(
        staff_specialties__specialty__name="Cardiology"
    ).filter(
        staff_specialties__specialty__name="Internal Medicine"
    ).distinct()
    # Count related objects - Staff with specialty counts
    staff_with_counts = CustomStaff.objects.annotate(
        specialty_count=Count("staff_specialties")
    ).filter(specialty_count__gte=2)
    # Group by and aggregate - Count how many staff have each specialty
    specialty_counts = Specialty.objects.annotate(
        staff_count=Count("staff_specialties")
    ).order_by("-staff_count")
    for specialty in specialty_counts:
        print(f"{specialty.name}: {specialty.staff_count} staff members")
    ```
##  Best Practices 
###  Model Design 
  1. **Use appropriate field types** \- Choose the most specific field type for your data
  2. **Define related_name** \- Always specify `related_name` for clear reverse relationships
  3. **Keep models focused** \- Each model should represent a single, well-defined concept
###  Relationships 
  1. **Choose the right relationship type** \- OneToOne for 1:1, ForeignKey for 1:many, join tables and "through" models for many:many
  2. **Use through models** \- To create a join table bridging two other entities, create a CustomModel representing the relationship
  3. **Handle deletions** \- Use `CASCADE` on join table foreign keys so associations are cleaned up automatically. Use `SET_NULL` when child records should survive parent deletion. Use `DO_NOTHING` only when you manage cleanup explicitly in plugin code
###  Performance 
  1. **Add indexes strategically** \- Index frequently filtered fields - foreign key fields are automatically indexed
  2. **Use select_related** \- For ForeignKey and OneToOneField to reduce queries
  3. **Use prefetch_related** \- For reverse ForeignKey fields (including join tables for many-to-many fields)
  4. **Avoid N+1 queries** \- Always prefetch related data when iterating
  5. **Use exists() for checks** \- More efficient than count() or len()
  6. **Use iterator() for large datasets** \- Reduces memory usage for processing many records
###  Data Integrity 
  1. **Enforce uniqueness with UniqueConstraint** \- Use `UniqueConstraint` in `Meta.constraints` to prevent duplicate data at the database level
  2. **Validate in model methods** \- Add custom validation in `clean()` method
  3. **Use transactions** \- Wrap multiple operations in atomic transactions
  4. **Handle DoesNotExist** \- Always catch exceptions when using `get()`
###  Testing 
  1. **Use model factories** \- Create test data with factory patterns
  2. **Test model methods** \- Verify custom model methods and properties
  3. **Test relationships** \- Ensure relationships work in both directions
  4. **Test data quality** \- The plugin is responsible for ensuring uniqueness and validity of foreign keys
  5. **Test edge cases** \- Test with null values, empty strings, boundary conditions

# Design Considerations

Source: https://docs.canvasmedical.com/sdk/custom-data-design-considerations/

Choosing the right storage technique prevents performance problems, data inconsistencies, and unnecessary code complexity down the road. This page describes common anti-patterns for each technique and recommends alternatives.
For an overview of available techniques, see the [Custom Data Overview](/sdk/custom-data/).
##  Extending SDK Models with Custom Data 
To attach custom fields to existing SDK models (Patient, Staff, etc.), use a [CustomModel](/sdk/custom-data-custom-models/) with a `OneToOneField` pointing at the SDK model. This gives you typed, indexed columns with full ORM support — `select_related`, reverse lookups via `related_name`, and compound filtering in a single query.
    ```python
    from canvas_sdk.v1.data import Patient, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import BooleanField, DO_NOTHING, IntegerField, OneToOneField, TextField
    class CustomPatient(Patient, ModelExtension):
        pass
    class PatientProfile(CustomModel):
        patient = OneToOneField(
            CustomPatient, to_field="dbid", on_delete=DO_NOTHING,
            related_name="profile"
        )
        preferred_language = TextField()
        risk_score = IntegerField()
        is_vip = BooleanField()
    ```
CustomModels with `OneToOneField` are preferred because they offer typed columns, indexing, compound queries, and a schema that is visible and self-documenting. See [Extending SDK Models](/sdk/custom-data-extending-sdk-models/) for details on proxy models and `related_name` namespacing.
For truly simple, one-off metadata that doesn't justify a table (e.g., a single configuration flag), an [AttributeHub](/sdk/custom-data-attribute-hubs/) can be a lighter-weight alternative.
##  AttributeHubs — When to Reconsider 
AttributeHubs use EAV (entity-attribute-value) storage and are standalone — not attached to any Canvas model. They are convenient for one-off state and configuration, but the same EAV limitations apply when used at scale. Their best application is storing a collection of attributes that will mainly be retrieved by identifier rather than by value.
###  Modeling entities with relationships 
If you have "departments" and need to assign staff to them, encoding `staff_id` as a string attribute means no JOINs, no referential integrity, potentially duplicated data. The plugin must manually maintain consistency.
**Use instead:** [CustomModels](/sdk/custom-data-custom-models/) with `ForeignKey` fields and junction tables handle relationships naturally, with ORM-level traversal and `prefetch_related` support.
###  Large homogeneous collections 
Storing thousands of hubs of `type="patient_visit"` where you need to filter, sort, or paginate across them becomes expensive. Each filter condition requires a JOIN to the attribute table.
**Use instead:** A [CustomModel](/sdk/custom-data-custom-models/) with typed, indexed columns. Filtering, sorting, and pagination use standard SQL operations.
###  Data requiring aggregation 
Trying to SUM, AVG, or COUNT across AttributeHub attributes requires joining to the attribute table and selecting the correct typed column (`int_value`, `decimal_value`, etc.) per attribute name. This is fragile and slow.
**Use instead:** [CustomModel](/sdk/custom-data-custom-models/) columns make Django ORM aggregation (`annotate`, `aggregate`) straightforward.
###  Data with a consistent schema 
If every hub of a given `type` has the same set of attributes, you've designed a schema — just without enforcement or indexes. You're paying the cost of EAV without the benefit of flexibility.
**Use instead:** A [CustomModel](/sdk/custom-data-custom-models/) gives you type safety, column-level indexes, and cleaner queries.
##  CustomModels — When to Reconsider 
CustomModels create real database tables with typed columns. They are the most powerful option but carry a commitment: tables can be added but never dropped via the SDK, and fields can be added but never altered or removed.
###  Simple metadata on existing models 
For a small number of independent metadata fields on an SDK model (e.g., a single `is_vip` flag on Patient), a full CustomModel with `OneToOneField` is the recommended approach — it gives you typed columns, indexing, and compound queries. However, if the overhead of a table feels excessive for truly one-off data, an [AttributeHub](/sdk/custom-data-attribute-hubs/) keyed by entity type and ID can serve as a lightweight alternative.
###  Highly dynamic or schemaless data 
If every record has different fields — for example, caching responses from external APIs where the payload varies per endpoint — a CustomModel forces a rigid schema. You'll accumulate nullable columns for each variation, and fields can never be dropped.
**Use instead:** [AttributeHubs](/sdk/custom-data-attribute-hubs/) for truly schemaless data, or a CustomModel with a single `JSONField` if you still want a table but need flexible contents.
###  Ephemeral data 
CustomModel tables are permanent. Once created, they cannot be dropped via the SDK. For short-lived data like session tokens, rate-limit windows, or temporary processing state, a persistent table is the wrong tool.
**Use instead:** The [Caching API](/sdk/caching) for data with a natural TTL. For semi-persistent unstructured state, [AttributeHubs](/sdk/custom-data-attribute-hubs/) are lighter weight.
###  Premature normalization 
Don't create five interrelated CustomModels with foreign keys when the data is simple and queried infrequently. Over-engineering the schema early is costly because tables cannot be dropped if you change your mind.
**Use instead:** Start with fewer models. A single `JSONField` column or an [AttributeHub](/sdk/custom-data-attribute-hubs/) can hold loosely structured data until access patterns stabilize and justify a richer schema.
##  Quick Reference 
Situation| Recommended Approach  
---|---  
Custom fields on Patient, Staff, or other SDK models| CustomModel with `OneToOneField`  
Provider preferences (notification settings, display options)| CustomModel with `OneToOneField`  
API sync cursors, external system state| AttributeHub  
Plugin configuration or feature flags| AttributeHub  
One-off key-value data unrelated to a Canvas model| AttributeHub  
Rapid prototyping before committing to a schema| AttributeHub  
Structured entities with a stable, known schema| CustomModel  
Relationships between entities (foreign keys, join tables)| CustomModel  
Data requiring compound filtering, sorting, or aggregation| CustomModel  
Data consumed by reports or analytics| CustomModel  
High-write-frequency counters or accumulators| CustomModel  
Short-lived data that should auto-expire| [Caching API](/sdk/caching)

# Extending SDK Models

Source: https://docs.canvasmedical.com/sdk/custom-data-extending-sdk-models/

##  Overview 
SDK models like `Patient`, `Staff`, and `Note` are shared across all plugins. To attach custom data or create relationships to these models from your [CustomModels](/sdk/custom-data-custom-models/), extend them with `ModelExtension` to create a plugin-private proxy model.
* * *
##  Creating a Model Extension 
Subclass the SDK model together with `ModelExtension`:
    ```python
    from canvas_sdk.v1.data import Staff, ModelExtension
    class CustomStaff(Staff, ModelExtension):
        pass
    ```
What happens automatically:
  - **`proxy = True`** is set by the `ModelExtensionMetaClass`. No new database table is created — the proxy shares the parent model's table.
  - **`app_label`** is set to your plugin name (derived from the module path).
  - `CustomStaff` behaves identically to `Staff` for queries — `CustomStaff.objects.all()` returns the same rows as `Staff.objects.all()`.
You can name the class anything, but it **must** subclass both a concrete SDK model and `ModelExtension`.
Extended SDK models may be defined anywhere in your plugin since they do not require database modifications. However, placing them in the `models` directory alongside your CustomModels is recommended for clarity.
* * *
##  Why Proxy Models? 
SDK models are shared across every plugin in the system. If two plugins each added a bare `related_name="biography"` on a `ForeignKey` pointing at `Staff`, Django would raise a clash error — both reverse relations would compete for the same attribute on the shared `Staff` class.
Proxy models solve this by giving each plugin its own private subclass of the SDK model. Because `CustomStaff` is a distinct model (even though it shares the same table), reverse relations registered on `CustomStaff` are scoped to the plugin that defined it. The shared SDK model stays clean and unaffected.
* * *
##  Referencing SDK Models from CustomModels 
When a CustomModel needs a `ForeignKey` or `OneToOneField` pointing at an SDK model, you have two approaches.
###  Approach 1: Via Proxy (Recommended) 
Create a `ModelExtension` proxy and point your relationship field at it. Because the target is plugin-private, `related_name` can be any simple name — no namespacing required.
    ```python
    from canvas_sdk.v1.data import Staff, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import DO_NOTHING, OneToOneField, TextField
    class CustomStaff(Staff, ModelExtension):
        pass
    class Biography(CustomModel):
        staff = OneToOneField(
            CustomStaff, to_field="dbid", on_delete=DO_NOTHING,
            related_name="biography"
        )
        text = TextField()
    ```
Reverse lookup works through the proxy:
    ```python
    staff = CustomStaff.objects.get(id="some-uuid")
    bio = staff.biography  # accesses the Biography via related_name
    ```
###  Approach 2: Direct SDK Model with Namespaced `related_name`
Point directly at the SDK model, but you **must** namespace the `related_name` to prevent collisions across plugins. Two formats are accepted:
Format| Example| Notes  
---|---|---  
`%(app_label)s_` prefix (recommended)| `related_name="%(app_label)s_biography"`| Django substitutes your plugin's `app_label` at class creation time  
Hardcoded plugin prefix| `related_name="my_plugin_biography"`| Works, but breaks if you rename the plugin  
`"+"`| `related_name="+"`| Disables the reverse relation entirely  
    ```python
    from canvas_sdk.v1.data import Staff
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import DO_NOTHING, OneToOneField, TextField
    class Biography(CustomModel):
        staff = OneToOneField(
            Staff, to_field="dbid", on_delete=DO_NOTHING,
            related_name="%(app_label)s_biography"
        )
        text = TextField()
    ```
###  Comparison 
| Via Proxy| Direct SDK Model  
---|---|---  
`related_name` namespacing required?| No| Yes  
Reverse lookup available?| Yes, via the proxy class| Yes, via the SDK model  
Reverse attribute name| Simple (e.g., `staff.biography`)| Prefixed (e.g., `staff.my_plugin_biography`)  
Extra class needed?| Yes (`ModelExtension` proxy)| No  
In most cases, Approach 1 is preferred — it keeps `related_name` values short and readable, and the proxy class is reusable across multiple CustomModels in the same plugin.
* * *
##  Proxying Related Objects with `proxy_field`
When you use `ModelExtension` proxies and follow related objects through ForeignKey fields, the returned instance is the base SDK class — not your proxy. For example:
    ```python
    from canvas_sdk.v1.data import Note, Patient, ModelExtension
    class CustomPatient(Patient, ModelExtension):
        def full_display_name(self):
            # custom method only available on CustomPatient
            return f"{self.first_name} {self.last_name} (DOB: {self.birth_date})"
    class CustomNote(Note, ModelExtension):
        pass
    note = CustomNote.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    note.patient                       # returns a Patient, not CustomPatient
    note.patient.full_display_name()   # AttributeError!
    ```
This happens because Django's ForeignKey descriptor resolves the relation to the concrete model (`Patient`), unaware of your proxy class. You would need an extra query to "re-fetch" the object as a `CustomPatient`.
###  The `proxy_field` descriptor 
`proxy_field` solves this by intercepting the ForeignKey access and transparently returning the proxy class instead:
    ```python
    from canvas_sdk.v1.data import Note, Patient, ModelExtension, proxy_field
    class CustomPatient(Patient, ModelExtension):
        def full_display_name(self):
            return f"{self.first_name} {self.last_name} (DOB: {self.birth_date})"
    class CustomNote(Note, ModelExtension):
        patient = proxy_field(CustomPatient)
    note = CustomNote.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    note.patient                       # returns a CustomPatient instance
    note.patient.full_display_name()   # works!
    ```
No extra queries are issued — `proxy_field` reuses the already-fetched row and swaps its Python class to the proxy. Because proxy models share the same database table, this is safe and efficient.
###  How it works 
`proxy_field` is a Python [descriptor](https://docs.python.org/3/howto/descriptor.html). When you declare `patient = proxy_field(CustomPatient)` on a model class:
  1. `__set_name__` runs at class creation time and finds the original FK descriptor (`patient`) from the parent class in the MRO.
  2. `__get__` delegates to that original descriptor to load the related object, then sets `__class__` on the result to your proxy class.
  3. `__set__` passes assignment through to the original descriptor, so `note.patient = some_patient` continues to work normally.
  4. Accessing the attribute on the class (e.g., `CustomNote.patient`) returns the descriptor itself, not a model instance.
###  When to use `proxy_field`
Use `proxy_field` when:
  - You have `ModelExtension` proxies for multiple SDK models and need to navigate between them while keeping access to your custom methods or `related_name` fields.
  - You want to avoid extra database queries to "re-fetch" a related object as the proxy type.
`proxy_field` is not needed when:
  - You don't add custom methods, properties or `related_name` fields to your proxy class.
  - You access the related object's fields directly (e.g., `note.patient.first_name`) without needing proxy-specific behavior.
###  Null foreign keys 
`proxy_field` handles nullable ForeignKeys safely — if the relation is `None`, it returns `None` without error:
    ```python
    note = CustomNote.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    note.patient  # returns None if the FK is null, not an error
    ```
* * *
##  Common Errors 
###  `ValueError`: non-namespaced `related_name` on SDK model target 
If you point a `ForeignKey` or `OneToOneField` directly at an SDK model with a plain `related_name`, installation will fail with:
    ```text
    ValueError: CustomModel 'Biography' declares related_name='biography' on field 'staff'
    targeting SDK model 'Staff'. To prevent collisions across plugins, use a namespaced
    related_name like related_name='%(app_label)s_biography', or related_name='+' to
    disable the reverse relation.
    ```
**Fix:** Either switch to a proxy target (Approach 1) or add the `%(app_label)s_` prefix to your `related_name` (Approach 2).
This validation applies to `ForeignKey` and `OneToOneField`. Fields targeting other CustomModels or proxy models are exempt because those targets are already plugin-private.

# Namespace Lifecycle

Source: https://docs.canvasmedical.com/sdk/custom-data-namespace-lifecycle/

Every plugin that uses custom data operates within a **namespace** — an isolated PostgreSQL schema that holds the plugin's AttributeHubs and CustomModels. During iterative development, namespaces accumulate tables, columns, and data that can get in the way. This page explains how namespaces are created and managed, and how to use the Canvas CLI to inspect and clean up namespaces as you work.
##  Namespace Naming Rules 
Namespace names use the format `org__name` (two parts separated by a double underscore). Each part must start with a lowercase letter and contain only lowercase letters, digits, and single underscores. The total length must not exceed **63 characters** (PostgreSQL's identifier limit).
Examples of valid names: `acme__shared_data`, `myorg__analytics`
##  How Namespaces Are Created 
A namespace is created automatically when the **first plugin** with `"access": "read_write"` is installed into it. The installation process:
  1. Creates a PostgreSQL schema named after the namespace
  2. Establishes two authentication keys (`namespace_read_access_key` and `namespace_read_write_access_key`) — auto-generated UUIDs by default, or values supplied by the installer (see [Pre-Supplying Keys at Creation](/sdk/custom-data-sharing-data/#pre-supplying-keys-at-creation))
  3. Stores the keys as secrets in the plugin
  4. Creates any CustomModel tables defined by the plugin
Subsequent plugins can join the namespace with the appropriate access key. See [Sharing Data](/sdk/custom-data-sharing-data/) for details on multi-plugin namespaces.
###  Installation Flow 
![](/assets/images/sdk/custom-data/installation_flowchart.jpg)
The path depends on the declared access level and whether the namespace already exists:
Declared Access| Namespace Exists| Key Provided| Result  
---|---|---|---  
`read_write`| No| Neither| Creates namespace and tables; auto-generates both keys  
`read_write`| No| Both `namespace_read_access_key` and `namespace_read_write_access_key`| Creates namespace and tables using the supplied keys (see [Pre-Supplying Keys at Creation](/sdk/custom-data-sharing-data/#pre-supplying-keys-at-creation))  
`read_write`| Yes| Valid `namespace_read_write_access_key`| Plugin installed, tables created  
`read_write`| Yes| Invalid or missing| Installation fails  
`read`| Yes| Valid `namespace_read_access_key`| Plugin installed with read access  
`read`| No| N/A| Installation fails  
`read`| Yes| Invalid or missing| Installation fails  
##  Development Workflow 
When developing a plugin with custom data, you'll typically iterate through cycles of changing your models, reinstalling the plugin, and testing. Each reinstall can leave behind tables from previous iterations — renamed models leave orphaned tables, and test data accumulates. The `canvas namespace` CLI commands let you inspect what's in a namespace and clean it up without having to connect to the database directly.
###  Typical Iteration Cycle 
  1. Edit your CustomModel definitions or manifest
  2. Reinstall the plugin: `canvas install my_plugin --host dev-instance`
  3. Test your changes
  4. If models were renamed or removed, use `canvas namespace reset` to clean up orphaned tables
  5. Repeat
##  CLI Commands 
All namespace commands require a running Canvas instance. Pass `--host` to specify which instance to connect to.
###  Listing Namespaces 
See all custom data namespaces on an instance:
    ```bash
    canvas namespace list --host dev-instance
    ```
Output shows each namespace with its total table count and the number of custom (non-system) tables:
    ```text
    acme_corp__shared_data    tables: 7    custom: 3
    acme_corp__analytics      tables: 5    custom: 1
    ```
###  Inspecting a Namespace 
View the tables and columns in a specific namespace:
    ```bash
    canvas namespace inspect acme_corp__shared_data --host dev-instance
    ```
Output separates system tables (managed by the framework) from custom tables (defined by your plugin), and shows column details for custom tables:
    ```text
    Namespace: acme_corp__shared_data
    System tables:
      namespace_auth       ~2 rows
      schema_version       ~2 rows
      custom_attribute     ~150 rows
      attribute_hub        ~3 rows
    Custom tables:
      customnote   ~25 rows
        dbid     bigint    not null
        title    text      nullable
        body     text      nullable
      specialty    ~8 rows
        dbid     bigint    not null
        name     character varying    nullable
    ```
This is useful for verifying that your models were created correctly after installation, or for understanding what's in a namespace before deciding whether to reset or drop it.
###  Resetting a Namespace 
Reset drops your custom tables and truncates the data in system tables, but preserves the namespace itself and its authentication keys. This is the right choice when you want to start fresh with your models while keeping the namespace intact for reinstallation.
By default, reset runs in **dry-run mode** and only shows what would happen:
    ```bash
    canvas namespace reset acme_corp__shared_data --host dev-instance
    ```
    ```text
    Namespace: acme_corp__shared_data
    Custom tables to drop:
      customnote    ~25 rows
      specialty     ~8 rows
    Data tables to truncate:
      custom_attribute    ~150 rows
      attribute_hub       ~3 rows
    This is a dry run. To execute, re-run with --execute
    ```
To actually perform the reset, add `--execute`. You will be prompted to confirm by typing the full namespace name:
    ```bash
    canvas namespace reset acme_corp__shared_data --host dev-instance --execute
    ```
    ```text
    This will reset namespace 'acme_corp__shared_data'. This cannot be undone.
    Type the full namespace name to confirm: acme_corp__shared_data
    Namespace 'acme_corp__shared_data' has been reset.
      Dropped tables: customnote, specialty
      Truncated tables: custom_attribute, attribute_hub
    ```
After a reset, reinstall your plugin to recreate the tables with your updated model definitions.
###  Dropping a Namespace 
Drop removes the entire namespace — the schema, all tables, all data, and all authentication keys. Use this when you want to completely remove a namespace and start over, or when you're done with a development namespace and want to clean up.
Dry-run mode (default):
    ```bash
    canvas namespace drop acme_corp__shared_data --host dev-instance
    ```
    ```text
    Namespace: acme_corp__shared_data
    All tables that will be dropped:
      attribute_hub        ~3 rows
      custom_attribute     ~150 rows
      customnote           ~25 rows
      schema_version       ~4 rows
      namespace_auth       ~2 rows
      specialty            ~8 rows
    This is a dry run. To execute, re-run with --execute
    ```
To execute:
    ```bash
    canvas namespace drop acme_corp__shared_data --host dev-instance --execute
    ```
After a drop, the next plugin installation with that namespace name will create it from scratch, generating new authentication keys. Any other plugins that were sharing the namespace will need to be reconfigured with the new keys.
##  Uninstalling and Reinstalling a Plugin 
Uninstalling a plugin **deletes its secrets** , including the system-generated `namespace_read_access_key` and `namespace_read_write_access_key`. The namespace schema and its data, however, **survive the uninstall**. This is by design: uninstalling a plugin should never destroy custom data, and a namespace shared by multiple plugins must not be torn down while another plugin is still using it.
Because the namespace still exists, reinstalling the plugin does **not** regenerate the keys — key generation only happens when the namespace is first created. The reinstalled plugin is therefore left without valid access keys and cannot read or write its own data, even though configuring the secrets appeared to succeed.
This applies in production as well as during development. To avoid getting stuck:
  - **Before uninstalling** , copy the namespace keys from the Canvas admin UI into an external secret store such as 1Password. On reinstall, set them back as plugin secrets and the plugin regains access immediately. (To find the keys: open the Canvas admin UI, find the plugin that created the namespace, and read the `namespace_read_access_key` / `namespace_read_write_access_key` secret values.)
  - **If the keys are already lost** , run `canvas namespace drop <namespace> --host <instance> --execute` to remove the namespace, then reinstall. Installation recreates the namespace and generates fresh keys. Any other plugins that were sharing the namespace must be reconfigured with the new keys.
##  When to Reset vs. Drop 
Scenario| Command  
---|---  
You renamed or removed a CustomModel and want to clean up the old table| `reset`  
Test data has accumulated and you want a clean slate| `reset`  
You changed your namespace name in the manifest| `drop` the old, then reinstall  
You're done developing and want to remove all traces| `drop`  
Other plugins share this namespace and you want to preserve their access| `reset` (keys are preserved)  
You want to regenerate the namespace authentication keys| `drop`, then reinstall  
You uninstalled a plugin and a reinstall can't access its data (keys were deleted)| `drop`, then reinstall — or restore the saved keys

# Quick Start

Source: https://docs.canvasmedical.com/sdk/custom-data-quick-start/

##  Getting Started 
To use custom data in your plugin, declare a `custom_data` section in your `CANVAS_MANIFEST.json` with a namespace and access level. The namespace is a unique identifier scoped to your organization (formatted as `organization__name` with a double underscore), and the access level controls whether the plugin can read only or read and write data. When the first `read_write` plugin is installed into a namespace, the system automatically initializes a data namespace, prepares tables, and generates `namespace_read_access_key` and `namespace_read_write_access_key` secrets that control access for other plugins joining the same namespace.
    ```json
    {
      "sdk_version": "0.1.4",
      "plugin_version": "1.0.0",
      "name": "my_plugin",
      "variables": [
        {"name": "namespace_read_write_access_key", "sensitive": false}
      ],
      "custom_data": {
        "namespace": "acme_corp__shared_data",
        "access": "read_write"
      }
    }
    ```
###  Step by Step 
  1. `canvas init`
  2. When prompted for a name, enter `Hello Custom Data`
  3. `cd hello-custom-data/hello_custom_data`
  4. Open `CANVAS_MANIFEST.json` in your preferred editor.
  5. Create a `custom_data` block:
         ```json
         "custom_data": {
           "namespace": "my_org__hello_custom_data",
           "access": "read_write"
         }
         ```
  6. Add `namespace_read_write_access_key` to the `secrets` array (the key will be generated by the system for you)
  7. Next, create a `models` directory under the root of your plugin hierarchy, sibling to `CANVAS_MANIFEST.json` and `handlers`
  8. Create an `__init__.py` file inside of `models` and open it in your editor.
  9. Declare the following classes within the `__init__.py` file:
         ```python
         from canvas_sdk.v1.data import Note, ModelExtension
         from canvas_sdk.v1.data.base import CustomModel
         from django.db.models import DO_NOTHING, OneToOneField, TextField
         class CustomNote(Note, ModelExtension):
             """Proxy model — see Extending SDK Models for why this exists."""
             pass
         class NoteTag(CustomModel):
             """Stores a plugin-assigned tag on a note."""
             note = OneToOneField(
                 CustomNote, to_field="dbid", on_delete=DO_NOTHING,
                 related_name="tag", primary_key=True
             )
             tagged_by = TextField()
         ```
  10. Open `handlers/event_handlers.py` in your editor. Update the imports:
         ```python
         from hello_custom_data.models import CustomNote, NoteTag
         ```
  11. In the code, replace uses of `Note` with `CustomNote`. These objects behave the same as the SDK model. (See [Extending SDK Models](/sdk/custom-data-extending-sdk-models/) for why proxy models are used.)
  12. Add the following lines **after** the `note` reference has been initialized in the code:
         ```python
         tag, created = NoteTag.objects.get_or_create(
             note=note,
             defaults={"tagged_by": "hello-custom-data"}
         )
         log.info(f"Note tagged by: {tag.tagged_by}")
         ```
  13. Install the plugin to your development environment
  14. Tail the logs with `canvas logs`
  15. Log into Canvas, navigate to a patient chart, and create a new note
In the logs you will see our message: `Note tagged by: hello-custom-data`
What just happened? When you installed the plugin, a new database namespace called `my_org__hello_custom_data` was created. Within the namespace are tables that hold information owned by, and managed by, the `my_org` plugins. The `NoteTag` model you defined turned into a PostgreSQL table with the following structure:
    ```sql
    create table my_org__hello_custom_data.notetag
    (
        note_id   bigint not null primary key,
        tagged_by text
    );
    ```
Creating the `NoteTag` record caused a new row to be inserted into the `notetag` table in the `my_org__hello_custom_data` namespace. This table is private to the namespace. The Note itself is unmodified — the `NoteTag` CustomModel stores the additional data in its own table and links back to the note via a `OneToOneField`.
[CustomModels](/sdk/custom-data-custom-models) let you define fully structured tables with typed fields and relationships — including linking to SDK models like Note, Patient, and Staff via `OneToOneField` or `ForeignKey`.
###  AttributeHub Alternative 
If you don't need a structured model and just want to store a simple key-value pair, you can use an [AttributeHub](/sdk/custom-data-attribute-hubs/) instead. Replace the `NoteTag` creation in `event_handlers.py` with:
    ```python
    from canvas_sdk.v1.data import AttributeHub
    from logger import log
    note_id = "89992c23-c298-4118-864a-26cb3e1ae822"
    hub = AttributeHub.objects.create(
        type="note_tag",
        id=f"note:{note_id}"
    )
    hub.set_attribute("tagged_by", "hello-custom-data")
    log.info(f"Note tagged by: {hub.get_attribute('tagged_by')}")
    ```
AttributeHubs are standalone key-value stores — they don't require a model definition or a `models` directory. They're a good fit for one-off state, configuration, and data that doesn't have a natural schema. See [Design Considerations](/sdk/custom-data-design-considerations/) for help choosing between the two approaches.

# Sharing Data

Source: https://docs.canvasmedical.com/sdk/custom-data-sharing-data/

Plugins can share data in two ways, depending on the relationship between the plugins:
Approach| Use Case| Coupling  
---|---|---  
**Namespace Sharing**|  Plugins owned by the same organization that need direct database access| Tight  
**API Sharing**|  Plugins owned by different organizations, or when loose coupling is preferred| Loose  
##  Namespace Sharing 
Namespace sharing allows multiple plugins to read from and write to the same database tables. This is ideal for organizations that want to build smaller, focused plugins instead of a single monolithic plugin. A plugin may reside within one namespace only. If it needs to access data from multiple namespaces, then it must do so via API calls.
###  When to Use Namespace Sharing 
  - Your organization owns multiple plugins that need to share data
  - You want to break a large plugin into smaller, maintainable pieces
  - You need direct database access for performance
  - You want to avoid the overhead of API calls between plugins
###  Namespace Lifecycle 
For a full overview of how namespaces are created, managed, and cleaned up during development, see [Namespace Lifecycle](/sdk/custom-data-namespace-lifecycle/).
###  Discovering Access Keys 
After the namespace is created, you can find the generated keys in the **Canvas admin UI** :
  1. Navigate to **Settings → Plugins**
  2. Find the plugin that created the namespace
  3. Click to view plugin details
  4. The `namespace_read_access_key` and `namespace_read_write_access_key` appear in the **Secrets** section
Share these keys securely with developers of other plugins that need access:
  - Share `namespace_read_access_key` with plugins that only need to read data
  - Share `namespace_read_write_access_key` with plugins that need to modify data
> **Important:** Store these keys in a secure location outside of Canvas, such as 1Password. Removing a key from the manifest's `secrets` array does **not** delete the stored value — it is preserved. However, **uninstalling the plugin deletes its secrets** , including the namespace keys. Because the namespace itself survives an uninstall, a later reinstall will not regenerate the keys, so a copy kept outside Canvas is the only way to restore access. See [Uninstalling and Reinstalling a Plugin](/sdk/custom-data-namespace-lifecycle/#uninstalling-and-reinstalling-a-plugin).
###  Pre-Supplying Keys at Creation 
By default, Canvas auto-generates the two access keys the first time a `read_write` plugin creates a namespace. You can also **supply both keys yourself** at that first install — pass them through the same `--secret` mechanism used for joins:
    ```bash
    canvas install my_plugin \
      --host demo.canvasmedical.com \
      --secret namespace_read_access_key=<your-read-key> \
      --secret namespace_read_write_access_key=<your-read-write-key>
    ```
When both keys are present at the install that creates the namespace, those plaintext values are what get hashed into the namespace's authentication table — Canvas does **not** generate fresh UUIDs.
Rules:
  - Supply **both** keys for your values to take effect. If you provide only one — or leave either value empty — Canvas silently ignores the supplied keys and auto-generates both instead. The install still succeeds; it does not fail.
  - Format is not enforced, but UUID4s are conventional.
  - This only applies to the install that **creates** the namespace. Subsequent joins validate against whatever was written at creation time.
  - If you supply neither key, behavior is unchanged: Canvas generates both for you.
When to use this:
  - You want the keys to be known and persisted outside Canvas before the namespace exists (for example, a deployment system that needs to seed sibling plugins with the same key without round-tripping through the Admin UI).
  - You're restoring access to a previously-dropped namespace and want to reuse known key values.
  - You want deterministic key values across test runs in CI.
###  Configuring Plugin Access 
Each plugin that joins a namespace must:
  1. **Declare the namespace** in `CANVAS_MANIFEST.json`
  2. **Include the access key name** in the manifest's `variables` array
  3. **Provide the access key** during installation
    ```json
    {
      "variables": [
        {"name": "namespace_read_write_access_key", "sensitive": false}
      ],
      "custom_data": {
        "namespace": "acme_corp__shared_data",
        "access": "read_write"
      }
    }
    ```
> Namespace access keys are declared with `"sensitive": false` so the value remains readable in the Admin UI's Secrets inline — that's the surface developers use to copy a key into a sibling plugin that joins the same namespace.
**Installing with the Canvas CLI (recommended):**
Provide the access key using the `--secret` flag:
    ```bash
    canvas install my_plugin \
      --host demo.canvasmedical.com \
      --secret namespace_read_write_access_key=3b35fad9-6462-4e83-83f5-c0e4bde49b71
    ```
**Alternative: Setting secrets via Admin UI:**
If you've already installed the plugin without the secret:
  1. Go to **Settings → Plugins → Your Plugin → Secrets**
  2. Set the `namespace_read_access_key` or `namespace_read_write_access_key` value
  3. **Reinstall the plugin** to pick up the secret
###  Manifest Configuration 
    ```json
    {
      "sdk_version": "0.1.4",
      "plugin_version": "1.0.0",
      "name": "my_plugin",
      "variables": [
        {"name": "namespace_read_write_access_key", "sensitive": false}
      ],
      "custom_data": {
        "namespace": "acme_corp__shared_data",
        "access": "read_write"
      }
    }
    ```
**Namespace naming requirements:**
  - Must contain `__` (double underscore) to separate organization from name
  - Cannot use reserved PostgreSQL names (`public`, `pg_catalog`, etc.)
  - Organizations and names must start with a letter
**Access levels:**
  - `read` \- Can only read data from the namespace
  - `read_write` \- Can read and write data, and create custom tables
###  Permissions and Restrictions 
Permission| `read`| `read_write`  
---|---|---  
Query AttributeHubs| ✅| ✅  
Query CustomModels| ✅| ✅  
Create/update/delete AttributeHubs| ❌| ✅  
Create/update/delete CustomModel records| ❌| ✅  
Create/update custom database tables| ❌| ✅  
###  Example: Sharing AttributeHubs 
AttributeHubs store standalone key-value data not attached to Canvas models.
**Plugin A (write access) - Creates configuration hub:**
    ```python
    # CANVAS_MANIFEST.json: "access": "read_write"
    from canvas_sdk.v1.data import AttributeHub
    # Create or retrieve a configuration hub
    config, created = AttributeHub.objects.get_or_create(type="clinic_config", id="main")
    config.set_attribute("max_daily_appointments", 50)
    config.set_attribute("appointment_duration_minutes", 30)
    config.set_attribute("accepting_new_patients", True)
    ```
**Plugin B (read access) - Reads configuration:**
    ```python
    # CANVAS_MANIFEST.json: "access": "read"
    from canvas_sdk.v1.data import AttributeHub
    config = AttributeHub.objects.with_only(
        attribute_names=["max_daily_appointments", "appointment_duration_minutes"]
    ).get(type="clinic_config", id="main")
    max_appointments = config.get_attribute("max_daily_appointments")  # 50
    duration = config.get_attribute("appointment_duration_minutes")  # 30
    ```
###  Example: Sharing CustomModels 
CustomModels allow you to define your own database tables with full ORM support.
**Important:** If multiple plugins need to share the same custom tables, each plugin must declare identical model definitions. The `read_write` plugin creates the tables; `read` plugins can query but not modify them.
**Shared model definition (must be identical in both plugins):**
    ```python
    # models/specialty.py
    from django.db import models
    from canvas_sdk.v1.data.base import CustomModel
    class Specialty(CustomModel):
        """A medical specialty that can be assigned to staff members."""
        name = models.CharField(max_length=100, unique=True)
        description = models.TextField(blank=True)
        requires_referral = models.BooleanField(default=False)
        class Meta:
            indexes = [
                models.Index(fields=['name']),
            ]
    ```
**Plugin A (write access) - Creates and manages specialties:**
    ```python
    # CANVAS_MANIFEST.json: "access": "read_write"
    from .models.specialty import Specialty
    # Create specialties
    cardiology = Specialty(
        name="Cardiology",
        description="Heart and cardiovascular system",
        requires_referral=True
    )
    cardiology.save()
    dermatology = Specialty(
        name="Dermatology",
        description="Skin conditions",
        requires_referral=False
    )
    dermatology.save()
    ```
**Plugin B (read access) - Queries specialties:**
    ```python
    # CANVAS_MANIFEST.json: "access": "read"
    from .models.specialty import Specialty
    # Query specialties (read operations work)
    referral_specialties = Specialty.objects.filter(requires_referral=True)
    for specialty in referral_specialties:
        print(f"{specialty.name}: {specialty.description}")
    # Write operations raise NamespaceWriteDenied
    specialty = Specialty.objects.first()
    specialty.description = "Updated"
    specialty.save()  # Raises NamespaceWriteDenied!
    ```
###  Error Handling 
When a plugin with `read` access attempts a write operation, a `NamespaceWriteDenied` exception is raised:
    ```python
    from canvas_sdk.v1.data.base import NamespaceWriteDenied
    try:
        hub.set_attribute("key", "value")
    except NamespaceWriteDenied as e:
        # "Write operation denied: namespace 'acme_corp__shared_data' is read-only.
        #  Plugin must declare 'read_write' access to perform write operations."
        log.error(f"Cannot write to shared namespace: {e}")
    ```
###  Troubleshooting 
**"NamespaceAccessError: secret 'namespace_read_access_key' is not configured"**
  - Add the secret name to the `secrets` array in your manifest
  - Ensure the secret has a value set in the Canvas UI
**"NamespaceAccessError: the key value is not a valid access key"**
  - Verify you're using the correct key from the namespace owner
  - Check that the key hasn't been regenerated
**"NamespaceAccessError: requests 'read_write' access but key only grants 'read'"**
  - You're using `namespace_read_access_key` but declared `"access": "read_write"`
  - Either change to `namespace_read_write_access_key` or change access to `"read"`
**"NamespaceWriteDenied: namespace is read-only"**
  - Your plugin has `"access": "read"` but is attempting a write operation
  - Change to `"access": "read_write"` and use `namespace_read_write_access_key`
##  API Sharing 
API sharing is the recommended approach when:
  - Plugins are owned by different organizations
  - You want loose coupling between plugins
  - You need fine-grained control over what data is exposed
  - You want to version your data interface independently
###  Example: Exposing Provider Profile Data 
    ```python
    from canvas_sdk.handlers.simple_api import SimpleAPI, APIKeyCredentials, api
    from canvas_sdk.effects.simple_api import JSONResponse
    from canvas_sdk.v1.data import Staff, ModelExtension
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import BooleanField, DO_NOTHING, OneToOneField, TextField
    class CustomStaff(Staff, ModelExtension):
        pass
    class StaffProfile(CustomModel):
        staff = OneToOneField(
            CustomStaff, to_field="dbid", on_delete=DO_NOTHING,
            related_name="profile"
        )
        specialty = TextField()
        accepting_patients = BooleanField(default=True)
    class ProfileAPI(SimpleAPI):
        """API to share staff profile data with authorized plugins."""
        PREFIX = "/staff-profiles"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            """Validate API key from requesting plugin."""
            from hmac import compare_digest
            provided_key = credentials.key
            expected_key = self.secrets["profile_api_key"]
            return compare_digest(provided_key.encode(), expected_key.encode())
        @api.get("/<staff_id>")
        def get_profile(self):
            """Return staff profile data."""
            staff_id = self.request.path_params["staff_id"]
            staff = CustomStaff.objects.select_related("profile").get(id=staff_id)
            # Explicitly choose what data to expose
            profile = {
                "staff_id": staff.id,
                "first_name": staff.first_name,
                "last_name": staff.last_name,
                "specialty": staff.profile.specialty,
                "accepting_patients": staff.profile.accepting_patients
            }
            return [JSONResponse(profile)]
    ```
###  Consuming Shared Data from Another Plugin 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response, JSONResponse
    from canvas_sdk.handlers.simple_api import SimpleAPI, api
    from canvas_sdk.utils import Http
    class MyAPI(SimpleAPI):
        PREFIX = "/retrieve"
        @api.get("/profile_for_staff/<staff_id>")
        def get_single_profile_via_api(self) -> list[Response | Effect]:
            staff_id = self.request.path_params["staff_id"]
            canvas_host = f"{self.environment['CUSTOMER_IDENTIFIER']}.canvasmedical.com"
            token = self.secrets["profile_api_token"]
            other_plugin_api = f"https://{canvas_host}/plugin-io/api/other_plugin/staff-profiles/{staff_id}"
            http = Http()
            response = http.get(other_plugin_api, headers={"Authorization": token})
            return [JSONResponse(response.json())]
    ```
###  API Sharing Best Practices 
  1. **Explicit Authorization** \- Always require authentication for APIs that expose plugin data
  2. **Minimal Exposure** \- Only expose the specific data fields that are necessary
  3. **Validate Requests** \- Check permissions and validate that the requester should have access
  4. **Document APIs** \- Provide clear documentation for plugins that will consume your API
  5. **Version APIs** \- Use versioning (e.g., `/v1/profiles`) to allow API evolution
  6. **Audit Access** \- Log API access for security and debugging purposes
  7. **Rate Limiting** \- Consider implementing rate limits to prevent abuse
###  Security Considerations 
  - **Never bypass plugin isolation** by attempting to access another plugin's database schema directly
  - **Use API keys or tokens** stored in secrets, never hardcoded in plugin code
  - **Implement proper error handling** that doesn't leak sensitive information
  - **Consider PHI implications** when exposing patient-related data via APIs
  - **Follow least privilege** principle - grant minimum necessary access
##  Choosing Between Namespace and API Sharing 
Factor| Namespace Sharing| API Sharing  
---|---|---  
**Ownership**|  Same organization| Different organizations  
**Coupling**|  Tight| Loose  
**Performance**|  Direct DB access| HTTP overhead  
**Schema Evolution**|  Coordinated updates| Independent versioning  
**Access Control**|  Binary (read/read_write)| Fine-grained  
**Setup Complexity**|  Lower| Higher

# Testing Custom Data

Source: https://docs.canvasmedical.com/sdk/custom-data-testing/

The Canvas SDK provides comprehensive testing utilities for custom data. Tests run within database transactions that automatically roll back, ensuring isolation between test cases.
##  Test Setup 
Install the test utilities extra to enable pytest-based testing:
    ```bash
    uv add "canvas[test-utils]"
    ```
Run your tests with:
    ```bash
    uv run pytest
    ```
Each test runs inside a transaction and automatically rolls back at the end, providing clean isolation without manual cleanup.
See [Testing Utilities](/sdk/testing-utils/) for complete setup instructions.
##  Creating Factories for Extended Models 
Define factories for extended models by extending the base SDK factories:
    ```python
    import factory
    from canvas_sdk.test_utils.factories import StaffFactory, PatientFactory
    from staff_plus.models import CustomStaff, CustomPatient
    class CustomStaffFactory(StaffFactory, factory.django.DjangoModelFactory[CustomStaff]):
        """Factory for creating CustomStaff instances."""
        class Meta:
            model = CustomStaff
    class CustomPatientFactory(PatientFactory, factory.django.DjangoModelFactory[CustomPatient]):
        """Factory for creating CustomPatient instances."""
        class Meta:
            model = CustomPatient
    ```
##  Creating Factories for Custom Models 
Define factories for your custom models with appropriate field values:
    ```python
    import factory
    from my_plugin.models import Specialty, StaffSpecialty
    from my_plugin.models import Biography
    class SpecialtyFactory(factory.django.DjangoModelFactory):
        """Factory for creating Specialty instances."""
        class Meta:
            model = Specialty
            django_get_or_create = ("name",)  # Avoid duplicate specialties
        name = factory.Faker("random_element", elements=[
            "Cardiology", "Dermatology", "Neurology", "Orthopedics",
            "Pediatrics", "Psychiatry", "Radiology", "Surgery"
        ])
    class BiographyFactory(factory.django.DjangoModelFactory):
        """Factory for creating Biography instances."""
        class Meta:
            model = Biography
        staff = factory.SubFactory(CustomStaffFactory)
        biography = factory.Faker("paragraph", nb_sentences=5)
        language = factory.Faker("language_name")
        practicing_since = factory.Faker("year")
    class StaffSpecialtyFactory(factory.django.DjangoModelFactory):
        """Factory for many-to-many relationship."""
        class Meta:
            model = StaffSpecialty
        staff = factory.SubFactory(CustomStaffFactory)
        specialty = factory.SubFactory(SpecialtyFactory)
    ```
##  Testing AttributeHub 
Test that AttributeHub stores and retrieves data correctly:

            model = CustomStaff
    def test_attribute_hub_creation():

        )
        assert created2 is False
        assert hub1.dbid == hub2.dbid
        assert hub2.get_attribute("data") == {"key": "value"}
    def test_attribute_hub_json_storage():
        """Test storing complex JSON in AttributeHub."""
        hub = AttributeHub.objects.create(

        )
        profile_data = {

            "languages": ["English", "Spanish"],
            "practicing_since": 2005,
            "accepting_patients": False
        }
        hub.set_attribute("profile", profile_data)
        hub_from_db = AttributeHub.objects.get(dbid=hub.dbid)

##  Testing with Factories 
Use factories to simplify test data creation:

    from django.db.models import OneToOneField, TextField, IntegerField, DO_NOTHING
    from canvas_sdk.test_utils.factories import StaffFactory
    from canvas_sdk.v1.data import Staff, ModelExtension

        class Meta:
            model = Biography
        staff = factory.SubFactory(CustomStaffFactory)
        biography = factory.Faker("paragraph", nb_sentences=5)
        language = factory.Faker("language_name")
        practicing_since = factory.Faker("year")
    def test_with_factories():

            model = StaffSpecialty
        staff = factory.SubFactory(CustomStaffFactory)
        specialty = factory.SubFactory(SpecialtyFactory)
    def test_many_to_many_with_factories():
        """Test many-to-many relationships with factories."""
        # Create staff-specialty associations
        ss1 = StaffSpecialtyFactory.create()

##  Testing proxy_field 
The `proxy_field` descriptor lets a `ModelExtension` proxy transparently return another proxy class from a ForeignKey lookup, so you can access custom methods on related objects:
    ```python
    from canvas_sdk.v1.data import Note, Patient, Staff, ModelExtension
    from canvas_sdk.v1.data.base import proxy_field
    from canvas_sdk.test_utils.factories import NoteFactory
    class CustomPatient(Patient, ModelExtension):
        @property
        def display_name(self) -> str:
            return f"{self.first_name} {self.last_name}"
    class CustomNote(Note, ModelExtension):
        # Without proxy_field, accessing note.patient returns a plain Patient.
        # With proxy_field, it returns a CustomPatient instead.
        patient = proxy_field(CustomPatient)
    def test_proxy_field_returns_proxy_class():
        """proxy_field swaps __class__ so the returned object is CustomPatient."""
        note = NoteFactory.create()
        custom_note = CustomNote.objects.select_related("patient").get(dbid=note.dbid)
        # The patient is a CustomPatient, not a plain Patient
        assert type(custom_note.patient) is CustomPatient
        assert custom_note.patient.display_name == (
            f"{note.patient.first_name} {note.patient.last_name}"
        )
    def test_proxy_field_handles_null():
        """proxy_field returns None when the FK is null."""
        note = NoteFactory.create(patient=None)
        custom_note = CustomNote.objects.get(dbid=note.dbid)
        assert custom_note.patient is None
    ```
##  Testing Best Practices 
  1. **Use factories** for consistent test data generation
  2. **Test isolation** \- Each test should be independent and not rely on data from other tests
  3. **Test both directions** of relationships (forward and reverse)
  4. **Verify persistence** by reloading objects from the database
  5. **Test edge cases** like None values, empty lists, and missing relationships
  6. **Use descriptive test names** that explain what is being tested
  7. **Test query optimization** to ensure prefetching works as expected
  8. **Verify constraints** like uniqueness behavior
  9. **Choose the right`on_delete`** \- ForeignKeys to SDK models (Staff, Patient, etc.) must use `DO_NOTHING` and related records must be deleted manually. ForeignKeys between your own CustomModels can use `CASCADE` for automatic cleanup

# Transactions

Source: https://docs.canvasmedical.com/sdk/custom-data-transactions/

##  Overview 
By default, each ORM operation in a plugin (`.save()`, `.create()`, `.update()`, `.delete()`) is committed to the database immediately. There is no automatic transaction wrapping your handler or protocol — if you perform three writes and the third one fails, the first two are already committed.
When you need multiple operations to succeed or fail together, use `transaction.atomic()`.
* * *
##  Using `transaction.atomic()`
Wrap related operations in an `atomic()` block to ensure all-or-nothing behavior:
    ```python
    from django.db.transaction import atomic
    with atomic():
        # All operations inside this block are part of a single transaction.
        # If any operation raises an exception, everything is rolled back.
        specialty, _ = Specialty.objects.get_or_create(name="Cardiology")
        StaffSpecialty.objects.filter(staff=staff).delete()
        StaffSpecialty.objects.bulk_create([
            StaffSpecialty(staff=staff, specialty=specialty)
        ])
        Biography.objects.create(staff=staff, biography="...")
    ```
If an exception occurs anywhere inside the block, all changes are rolled back — the database is left as it was before the block started.
* * *
##  When to Use Transactions 
Use `transaction.atomic()` when your handler performs **multiple related writes** that should not be partially applied:
  - **Replacing associations** — deleting existing records and creating new ones (e.g., replacing a staff member's specialties). Without a transaction, a failure after the delete leaves the staff member with no specialties.
  - **Creating a parent and its children** — e.g., creating a `Biography` and several `Language` records in one request. A partial failure could leave orphaned or incomplete data.
  - **Coordinated updates** — updating multiple models that must stay consistent with each other.
You do **not** need a transaction for:
  - A single `.create()`, `.save()`, or `.update()` call — these are already atomic on their own.
  - Read-only operations — `SELECT` queries don't modify data.
* * *
##  Example: Multi-Model Upsert 
This example accepts a JSON payload and upserts a staff profile spanning multiple CustomModels. The `atomic()` block ensures that either the entire profile is saved or nothing is:
    ```python
    from django.db.transaction import atomic
    from canvas_sdk.effects.simple_api import JSONResponse
    from canvas_sdk.handlers.simple_api import SimpleAPI, api
    class ProfileAPI(SimpleAPI):
        PREFIX = "/profile"
        @api.post("/v2/<staff_id>")
        def post_profile(self):
            with atomic():
                staff_id = self.request.path_params["staff_id"]
                json_body = self.request.json()
                staff = CustomStaff.objects.get(id=staff_id)
                # Upsert languages
                for name in json_body.get("languages", []):
                    Language.objects.get_or_create(name=name, staff=staff)
                # Replace specialty associations
                specialties = []
                for name in json_body.get("specialties", []):
                    specialty, _ = Specialty.objects.get_or_create(name=name)
                    specialties.append(specialty)
                StaffSpecialty.objects.filter(staff=staff).delete()
                StaffSpecialty.objects.bulk_create([
                    StaffSpecialty(staff=staff, specialty=s) for s in specialties
                ])
                # Upsert biography
                biography_text = json_body.get("biography")
                Biography.objects.update_or_create(
                    staff=staff,
                    defaults={
                        "biography": biography_text,
                        "practicing_since": json_body.get("practicing_since"),
                        "is_accepting_patients": json_body.get("accepting_patients"),
                    },
                )
            return [JSONResponse({"status": "ok"})]
    ```
If any operation inside the `atomic()` block raises an exception — a constraint violation, an unexpected data type, a model validation error — the entire block is rolled back and no partial data is written.
* * *
##  How It Works 
Plugin code runs inside a database context that sets the PostgreSQL `search_path` to the plugin's namespace. `transaction.atomic()` operates on this same connection automatically — no `using=` parameter is needed.
Under the hood, `atomic()` issues a `SAVEPOINT` (for nested usage) or manages the transaction directly. When the block exits cleanly, the transaction is committed. When an exception propagates out, it is rolled back.
* * *
##  Nesting 
`atomic()` blocks can be nested. Inner blocks use PostgreSQL savepoints, so a failure in an inner block rolls back only that block's changes (not the entire outer transaction), provided you catch the exception:
    ```python
    from django.db.transaction import atomic
    with atomic():
        Specialty.objects.create(name="Cardiology")
        try:
            with atomic():
                Specialty.objects.create(name="Neurology")
                raise ValueError("something went wrong")
        except ValueError:
            pass  # Only the "Neurology" insert is rolled back
        # "Cardiology" is still pending and will be committed
    ```
If the exception is **not** caught, it propagates to the outer block and rolls back everything.
* * *

# Custom Data

Source: https://docs.canvasmedical.com/sdk/custom-data/

##  Overview 
The Canvas SDK provides two techniques for storing custom data in your plugins, allowing you to define fully structured data models with relationships among entities, or create flexible key-value stores:
  1. **[CustomModels](/sdk/custom-data-custom-models/)** \- Build your own data model or expand the Canvas data model by adding fully structured tables with typed fields, relationships, and indexes
  2. **[AttributeHubs](/sdk/custom-data-attribute-hubs/)** \- Store arbitrary key-value pairs and JSON data independently of the Canvas data model
Each technique serves different use cases and provides different levels of structure and type safety. Both techniques may be used together.
##  When to Use Each Technique 
###  CustomModels 
Use this when you need structured, typed data with relationships and normalized data. CustomModels can also extend existing SDK models (like Patient or Staff) with custom fields via `OneToOneField`, `ForeignKey`, and `ManyToManyField`.
**Best for:**
  - Structured data with a stable, known schema
  - Custom fields on existing SDK models (e.g., provider preferences, patient flags)
  - Relationships between entities (foreign keys, join tables)
  - Data requiring compound filtering, sorting, or aggregation
  - Data consumed by reports or analytics
**Example use cases:**
  - Provider specialties and certifications
  - Adding practice-specific fields to patients or staff
  - Linking `Staff` to `Note` creating a `supervising_provider` association
  - Custom workflows and forms
  - Integration-specific data structures
  - Practice-specific business operation concepts and logic
[Learn more about CustomModels →](/sdk/custom-data-custom-models/)
###  AttributeHubs 
AttributeHubs provide a key/value and document store free from the burden of defining any schema or linking to Canvas models. They are for storing irregular or unstructured information that doesn't have a natural home. Whereas CustomModels build upon the Canvas data model, AttributeHubs allow easy, standalone persistence of information. Use this when you need to store data that doesn't naturally belong to any existing or imagined model.
**Best for:**
  - Cross-cutting state that spans multiple models (sync cursors, external IDs)
  - One-off or small-collection configuration and state
  - Data with no natural schema (varying fields per record)
  - External system state tracking
**Example use cases:**
  - API synchronization state
  - External system identifiers
  - Plugin configuration and feature flags

For details on how multiple plugins can share a namespace using these keys, see the [Sharing Data](/sdk/custom-data-sharing-data/) guide. For managing API tokens and other sensitive configuration, see [Managing Secrets](/sdk/secrets/).
##  Caching 
If your use case represents transient data that should expire via TTL, use the [Caching API](/sdk/caching) instead of the Custom Data features.
##  Data Privacy and Plugin Isolation 
All custom data created by a plugin — whether using CustomModels or AttributeHubs — is scoped to a namespace. This isolation ensures that plugins cannot directly access or modify another plugin's data, maintaining security and data integrity across the system.
Plugins may share data in two ways:
  - By explicit co-location within a namespace, allowing direct database access
  - By publishing [Simple API](/sdk/handlers-simple-api-http) endpoints
[Learn more about data sharing](/sdk/custom-data-sharing-data)
###  Data Isolation 
**CustomModels** created by a plugin exist within namespaces. Tables and data are completely isolated from other namespaces.
    ```python
    # In a plugin named "my_plugin": Creates a table "specialty" in the "my_plugin" namespace
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import TextField
    class Specialty(CustomModel):
        name = TextField()
    ```
    ```python
    # In a plugin named "your_plugin": Creates a table "specialty" in the "your_plugin" namespace
    from canvas_sdk.v1.data.base import CustomModel
    from django.db.models import TextField
    class Specialty(CustomModel):
        name = TextField()
    # In "your_plugin": Cannot access the "my_plugin" Specialty model or data
    ```
**AttributeHubs** similarly store data within the plugin's namespace and are not accessible to plugins in other namespaces.
##  Testing Custom Data 
The Canvas SDK provides comprehensive testing utilities for all custom data approaches. See the [Testing Custom Data](/sdk/custom-data-testing/) guide for detailed examples and best practices.
##  Sharing Data 
Use APIs to make data available and accessible to and from other plugins and external services. See the [Sharing Data](/sdk/custom-data-sharing-data/) guide for detailed examples and best practices.
##  Read Replica Databases 
All the data managed by plugin is available via the database read replica. To access it, alter the PostgreSQL [search_path](https://www.postgresql.org/docs/18/ddl-schemas.html#DDL-SCHEMAS-PATH) to include the namespaces that you intend to query.
##  Limitations (for Safety) 
  - Values stored in `text` and `json` fields may not exceed 1mb as measured by character count.
  - Bulk operations (e.g., `bulk_create`) are limited to 10,000 records at a time.

# AllergyIntolerance

Source: https://docs.canvasmedical.com/sdk/data-allergy-intolerance/

##  Introduction 
The `AllergyIntolerance` model represents a known risk, specific to a patient, of a harmful or undesirable physiological response associated with exposure to a substance.
##  Basic usage 
To get an allergy intolerance by identifier, use the `get` method on the `AllergyIntolerance` model manager:
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    allergy = AllergyIntolerance.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the allergy intolerances for a patient can be accessed with the `allergy_intolerances` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    allergies = patient.allergy_intolerances.all()
    ```
If you have a patient ID, you can get the allergies for the patient with the `for_patient` method on the `AllergyIntolerance` model manager:
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    allergies = AllergyIntolerance.objects.for_patient(patient_id)
    ```
##  Codings 
The codings for an allergy intolerance can be accessed with the `codings` attribute on an `AllergyIntolerance` object:
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    from logger import log
    allergy = AllergyIntolerance.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in allergy.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Allergy intolerances can be filtered by any attribute that exists on the model.
Filtering for allergy intolerances is done with the `filter` method on the `AllergyIntolerance` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    allergies = AllergyIntolerance.objects.filter(status="active")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    from canvas_sdk.value_set.v2022.allergy import EggSubstance
    allergies = AllergyIntolerance.objects.find(EggSubstance)
    ```

# Appointment

Source: https://docs.canvasmedical.com/sdk/data-appointment/

##  Introduction 
The `Appointment` model represents a single scheduled meeting from a patient, that may be in the future or past.
##  Basic usage 
To get an appointment by identifier, use the `get` method on the `Appointment` model manager:
    ```python
    from canvas_sdk.v1.data.appointment import Appointment
    appointment = Appointment.objects.get(id="f53626e4-0683-43ac-a1b7-c52815639ce2")
    ```
If you have a patient object, the appointments for a patient can be accessed with the `appointments` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    appointments = patient.appointments.all()
    ```
To get appointments part of a recurrence.
    ```python
    from canvas_sdk.v1.data.appointment import Appointment
    appointment = Appointment.objects.get(id="f53626e4-0683-43ac-a1b7-c52815639ce2")
    # parent appointment
    parent_appointment = appointment.parent_appointment
    # children appointments
    children = parent_appointment.children.all()
    ```
##  Filtering 
Appointments can be filtered by any attribute that exists on the model.
Filtering for appointments is done with the `filter` method on the `Appointment` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.appointment import Appointment, AppointmentProgressStatus
    appointments = Appointment.objects.filter(status=AppointmentProgressStatus.CONFIRMED)
    ```
###  Filtering by External Identifiers 
To query Appointments by external identifiers, the `external_identifiers` relation can be used with double-underscores to identify values stored on the AppointmentExternalIdentifier model. For example:
    ```python
    from canvas_sdk.v1.data.appointment import Appointment
    appointment = Appointment.objects.filter(
        external_identifiers__system="COMPANY_IDENTIFIER",
        external_identifiers__value="ejNoTa5vKzoT9oSjg87MVB").first()

# BannerAlert

Source: https://docs.canvasmedical.com/sdk/data-banner-alert/

##  Introduction 
The `BannerAlert` model represents alerts associated with [Patient](/sdk/data-patient/#patient) records. This page deals with data retrieval. To create or remove `BannerAlert` records, see [Banner Alert Effects](/sdk/effect-banner-alerts/).
##  Usage 
The `BannerAlert` model can be used to find all of the banner alert records linked to a patient. For example, to find all of the banner alerts for a patient, the `Patient.banner_alerts` method can be used:
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> patient_banner_alerts = patient_1.banner_alerts.all()
    >>> print([item.narrative for item in patient_banner_alerts])
    ['Patient spits when angry', 'Confirm contact info']
    ```
##  Filtering 
The `filter` method can be used to filter by desired attributes. The following examples show commonly used operations to filter banner alert data:
**Show a Patient's active BannerAlert records from the 'foo' plugin in order of descending creation date**
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> banner_alerts = patient_1.banner_alerts.filter(status='active', plugin_name='foo').order_by("created")
    >>> print([item.narrative for item in banner_alerts])
    ['foo', 'bar']
    ```

# BillingLineItem

Source: https://docs.canvasmedical.com/sdk/data-billing-line-item/

##  Introduction 
The `BillingLineItem` model represents billing line items linked to [Notes](/sdk/data-note) that can be found in the note footer. BillingLineItems are also linked to [Patient](/sdk/data-patient/#patient) instances.
##  Usage 
The `BillingLineItem` model can be used to find all of the billable codes linked to a patient note. For example, to find all of the current billing line items for a note, the `Note.billing_line_items` method can be used:
    ```python
    >>> from canvas_sdk.v1.data.note import Note
    >>> from canvas_sdk.v1.data.billing import BillingLineItemStatus
    >>> note_1 = Note.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> note_1_billing_line_items = note_1.billing_line_items.filter(status=BillingLineItemStatus.ACTIVE)
    >>> print([item.cpt for item in note_1_billing_line_items])
    ['99213', '90703']
    ```
Alternatively, you could find all the `BillingLineItem` instances for a single `Patient`:
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> patient_billing_line_items = patient_1.billing_line_items.all()
    >>> print([item.cpt for item in patient_billing_line_items])
    ['99213', '90703', '76942', '67505']
    ```
You can also access all `BillingLineItemModifier`s associated with a `BillingLineItem`:
    ```python
    >>> from canvas_sdk.v1.data.billing import BillingLineItem, BillingLineItemModifier
    >>> line_item = BillingLineItem.objects.get(id="b80b1cdc2e6a4aca90ccebc02e683f35")
    >>> line_item_modifiers = line_item.modifiers.all()
    >>> print([mod.code for mod in line_item_modifiers])
    ['25', '59']
    ```
##  Filtering 
The `filter` method can be used to filter by desired attributes. The following examples show commonly used operations to filter billing line item data:
**Show a Patient's active BillingLineItems that start with '99-' in order of descending charge amount**
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> from canvas_sdk.v1.data.billing import BillingLineItemStatus
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> office_visit_charges = patient_1.billing_line_items.filter(status=BillingLineItemStatus.ACTIVE, cpt__startswith='99').order_by("charge")
    >>> print([(item.cpt, item.charge,) for item in office_visit_charges])
    [('99215', 200.00), ('99215', 190.00), ('99214', 100.00), ('99213', 80.00)]
    ```
**Find All Removed BillingLineItems from a Note**
    ```python
    >>> import arrow
    >>> from canvas_sdk.v1.data.note import Note
    >>> from canvas_sdk.v1.data.billing import BillingLineItemStatus
    >>> note_1 = Note.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> note_1_removed_items = note_1.billing_line_items.filter(status=BillingLineItemStatus.REMOVED)
    >>> print([item.cpt for item in note_1_removed_items])
    ['11901', '00950']
    ```

# BusinessLine

Source: https://docs.canvasmedical.com/sdk/data-business-line/

##  Introduction 
The `BusinessLine` model represents a group of [Patients](/sdk/data-patient/#patient) that share a common brand under an [Organization](/sdk/data-organization).
##  Usage 
The `BusinessLine` model can be used to find all of the patients for a given Business Line:
    ```python
    >>> from canvas_sdk.v1.data import BusinessLine
    >>> business_line = BusinessLine.objects.get(id="ff844d60Od18466698dc645PtYZ3019Tt")
    >>> business_line_patients = business_line.patients.all()
    >>> print([patient.first_name for patient in business_line_patients])
    ['George', 'Louise', 'Julia']
    ```
You can also access a patient's Business Line from the `Patient` model:
    ```python
    >>> from canvas_sdk.v1.data import Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> patient_business_line = patient_1.business_line
    >>> print(patient_business_line.name)
    'New Patients that love cheese'
    ```
And you can also access all of the Business Lines under a given Organization:
    ```python
    >>> from canvas_sdk.v1.data import Organization
    >>> organization = Organization.objects.first()
    >>> organization_business_lines = organization.business_lines.all()
    >>> print([business_line.name for business_line in organization_business_lines])
    ['New Patients that love cheese', 'Spanish Speaking Patients', 'One Medical']
    ```
##  Filtering 
The `filter` method can be used to filter by desired attributes. The following examples show commonly used operations to filter Business Line data:
**Show an Organization's Business Lines that are active and in the 732 area code**
    ```python
    >>> from canvas_sdk.v1.data import BusinessLine, Organization
    >>> org = Organization.objects.first()
    >>> active_732_business_lines = BusinessLine.objects.filter(organization=org, active=True, area_code="732")
    >>> print([business_line.name for business_line in active_732_business_lines])
    ['Foo', 'Bar']
    ```

##  Introduction 
The `Calendar` model represents a Calendar in Canvas. Calendars are used to organize events for providers and can be either Clinic or Administrative type.
##  Basic usage 
To get a calendar by identifier, use the `get` method on the `Calendar` model manager:
    ```python
    from canvas_sdk.v1.data.calendar import Calendar
    calendar = Calendar.objects.get(id="f53626e4-0683-43ac-a1b7-c52815639ce2")
    ```
##  Events 
The events associated with a calendar can be accessed with the `events` attribute on a `Calendar` object:
    ```python
    from canvas_sdk.v1.data.calendar import Calendar
    calendar = Calendar.objects.get(id="f53626e4-0683-43ac-a1b7-c52815639ce2")
    events = calendar.events.all()
    ```
To get a specific event by identifier:
    ```python
    from canvas_sdk.v1.data.calendar import Event
    event = Event.objects.get(id="a1b2c3d4-5678-90ab-cdef-1234567890ab")
    ```
##  Filtering 
Calendars and events can be filtered by any attribute that exists on the model.
Filtering is done with the `filter` method on the model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.calendar import Calendar
    # Filter calendars by title
    calendars = Calendar.objects.filter(title__icontains="Clinic")
    ```
###  By calendar name 
To filter calendars by a specific provider name, calendar type, and location, use the `for_calendar_name` method:
    ```python
    from canvas_sdk.v1.data.calendar import Calendar
    calendars = Calendar.objects.for_calendar_name(
        provider_name="Dr. Smith",
        calendar_type="Clinic",
        location="Main Office"
    )
    ```

# CancelPrescriptionResponse

Source: https://docs.canvasmedical.com/sdk/data-cancel-prescription-response/

##  Introduction 
The `CancelPrescriptionResponse` model captures the response to a [CancelPrescription](/sdk/data-cancel-prescription) request. Each response is linked one-to-one to the request that produced it.
##  Basic usage 
To get a cancel prescription response by identifier, use the `get` method on the `CancelPrescriptionResponse` model manager:
    ```python
    from canvas_sdk.v1.data import CancelPrescriptionResponse
    response = CancelPrescriptionResponse.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the cancel prescription responses for a patient can be accessed with the `cancel_prescription_responses` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    responses = patient.cancel_prescription_responses.all()
    ```
Or, from a cancel prescription, reach its response with the `response` attribute:
    ```python
    from canvas_sdk.v1.data import CancelPrescription
    cancel = CancelPrescription.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    response = cancel.response
    ```

# CancelPrescription

Source: https://docs.canvasmedical.com/sdk/data-cancel-prescription/

##  Introduction 
The `CancelPrescription` model is the anchor for the CancelPrescription command — a request to cancel a patient's prescription, recorded on a Note.
##  Basic usage 
To get a cancel prescription by identifier, use the `get` method on the `CancelPrescription` model manager:
    ```python
    from canvas_sdk.v1.data import CancelPrescription
    cancel = CancelPrescription.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the cancel prescriptions for a patient can be accessed with the `cancel_prescriptions` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    cancels = patient.cancel_prescriptions.all()
    ```
Or, from a prescription, reach its cancellations with the same `cancel_prescriptions` attribute:
    ```python
    from canvas_sdk.v1.data import Prescription
    prescription = Prescription.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    cancels = prescription.cancel_prescriptions.all()
    ```
##  Committed records 
The `committed` method returns cancel prescriptions that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import CancelPrescription
    committed_cancels = CancelPrescription.objects.committed()
    ```
##  Attributes

# CanvasUser

Source: https://docs.canvasmedical.com/sdk/data-canvasuser/

##  Introduction 
The `CanvasUser` model represents a Canvas User. This could be linked to a staff member or a patient. This model isn't meant to be referenced directly, but is sometimes used to attribute a record to user.
##  Basic usage 
To get a user by identifier, use the `get` method on the `CanvasUser` model manager:
    ```python
    from canvas_sdk.v1.data import CanvasUser
    user = CanvasUser.objects.get(dbid=123)
    ```
##  Filtering 
Users can be filtered by any attribute that exists on the model.
Filtering for users is done with the `filter` method on the `CanvasUser` model manager.
###  By attribute 
Specify attributes with `filter` to filter by those attributes:
    ```python
    from canvas_sdk.v1.data import CanvasUser
    users = CanvasUser.objects.filter(phone_number="1111111111", email="test@canvasmedical.com")
    ```
##  Attributes 
###  User

# CareTeam

Source: https://docs.canvasmedical.com/sdk/data-care-team/

##  Introduction 
The `CareTeam` model represents a collection of [Staff](/sdk/data-staff/#staff) that are responsible for the care of a [Patient](/sdk/data-patient/#patient).
##  Usage 
There are 2 data models associated with Care Teams - `CareTeamMembership` and `CareTeamRole`. The `CareTeamRole` model stores all of the available roles that are available to be filled by staff members (i.e. _Physician_ , _Nurse Practitioner_ , etc.). For example, the following code will show the names of active roles that are available in a Canvas instance:
    ```python
    >>> from canvas_sdk.v1.data.care_team import CareTeamRole
    >>> active_care_team_roles = CareTeamRole.objects.filter(active=True)
    >>> role_names = [role.display for role in active_care_team_roles]
    >>> print(role_names)
    ['Primary care physician', 'Physician', 'Physician assistant', 'Nurse practitioner', 'Health coach', 'Care coordinator']
    ```
The `CareTeamMembership` model connects patients, staff members and their associated roles to make up the assembly of a patient's Care Team. To retrieve staff members and their respective roles on a patient's care team, the `care_team_memberships` attribute available on a [Patient](/sdk/data-patient/#patient) instance can be used:
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> patient_1_care_team = patient_1.care_team_memberships.all()
    >>> print([(ctm.role.display, ctm.staff,) for ctm in patient_1_care_team])
    [('Primary care physician', <Staff: Steven Magee>), ('Nurse practitioner', <Staff: Annalies Hines>), ('Physician assistant', <Staff: Erik McDonald>)]
    ```
###  External care team members 
A care team can also include external members — providers who are not [Staff](/sdk/data-staff#staff) on the Canvas instance. An external membership has no `staff`. Instead, its `organizational_entity` links to an [OrganizationalEntity](/sdk/data-organizational-entity/#organizationalentity) that describes the external provider. When that entity is a [ServiceProvider](/sdk/data-serviceprovider/#service-provider), the membership's `service_provider` property resolves directly to it, so you can read the provider's contact details — such as `business_fax` — without leaving the plugin.
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> external_member = patient_1.care_team_memberships.filter(staff__isnull=True).first()
    >>> external_member.service_provider.business_fax
    '18005551234'
    ```
The `service_provider` property returns `None` for internal (staff-backed) memberships, and for external members whose organizational entity is not a `Service Provider`.
##  Filtering 
The `filter` method can be used to filter by desired attributes. The following examples show commonly used operations to filter care team data:
**Find a patient's care team lead**
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> from canvas_sdk.v1.data.care_team import CareTeamMembershipStatus
    >>> patient_1 = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> patient_1_care_team_lead = patient_1.care_team_memberships.filter(lead=True, status=CareTeamMembershipStatus.ACTIVE).first()
    >>> assert patient_1_care_team_lead is not None
    >>> print((patient_1_care_team_lead.staff, patient_1_care_team_lead.role,))
    (<Staff: Steven Magee>, <CareTeamRole: Primary care physician>)
    ```
**Find all Patients that have a Certain Staff Member on their Care Team**
    ```python
    >>> from canvas_sdk.v1.data.staff import Staff
    >>> from canvas_sdk.v1.data.care_team import CareTeamMembershipStatus
    >>> staff_member = Staff.objects.get(id="3640cd20de8a470aa570a852859ac87e")
    >>> staff_care_teams = staff_member.care_team_memberships.filter(status=CareTeamMembershipStatus.ACTIVE)
    >>> print([(ctm.patient, ctm.lead,) for ctm in staff_care_teams])
    [(<Patient: Danny Boy>, True), (<Patient: Sally Mae>, False)]
    ```
##  Attributes

# Change Medication

Source: https://docs.canvasmedical.com/sdk/data-change-medication/

##  Introduction 
The `ChangeMedication` model represents a record of a Change Medication command, used to update the directions (sig) of a medication already on a patient's medication list without issuing a new prescription.
##  Basic usage 
To get a change medication by identifier, use the `get` method on the `ChangeMedication` model manager:
    ```python
    from canvas_sdk.v1.data import ChangeMedication
    change_medication = ChangeMedication.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    ```
If you have a patient object, the change medications for a patient can be accessed with the `change_medications` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    change_medications = patient.change_medications.all()
    ```
You can also access the referenced medication with the `medication` attribute:
    ```python
    from canvas_sdk.v1.data import ChangeMedication
    change_medication = ChangeMedication.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    medication = change_medication.medication
    ```
Or for a given medication, you can access all change medication records:
    ```python
    from canvas_sdk.v1.data import Medication
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    change_medications = medication.change_medications.all()
    ```
##  Committed records 
The `committed` method returns change medications that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import ChangeMedication
    committed_change_medications = ChangeMedication.objects.committed()
    ```

# ChargeDescriptionMaster

Source: https://docs.canvasmedical.com/sdk/data-charge-description-master/

##  Introduction 
The `ChargeDescriptionMaster` model represents a billing charge in Canvas that can be added to the note footer.
##  Usage 
The `ChargeDescriptionMaster` model can be filtered by any of its attributes, including `cpt_code`, `name`, and `short_name`:
    ```python
    >>> from canvas_sdk.v1.data import ChargeDescriptionMaster
    >>> office_visit_charges = ChargeDescriptionMaster.objects.filter(cpt_code__startswith="99")
    >>> print([charge.short_name for charge in office_visit_charges])
    ["Office outpatient visit 40 minutes", "Office outpatient visit 25 minutes", "Office outpatient visit 10 minutes"]
    ```
You can also access `PayorSpecificCharge`s from the `ChargeDescriptionMaster` model:
    ```python
    >>> from canvas_sdk.v1.data import ChargeDescriptionMaster
    >>> office_visit_40min = ChargeDescriptionMaster.objects.filter(cpt_code="99215").first()
    >>> payor_specific_charges = office_visit_40min.transactor_charges.all()

# ChartSectionReview

Source: https://docs.canvasmedical.com/sdk/data-chart-section-review/

##  Introduction 
The `ChartSectionReview` model represents a reviewed chart section captured on a note, with its pre-rendered content. When a provider reviews a chart section during a visit, Canvas stores a snapshot of that section's content at the time of review.
##  Basic usage 
To get a chart section review by identifier, use the `get` method on the `ChartSectionReview` model manager:
    ```python
    from canvas_sdk.v1.data.chart_section_review import ChartSectionReview
    review = ChartSectionReview.objects.get(id="b5a0c1d2-e3f4-5678-9abc-def012345678")
    ```
If you have a patient object, the chart section reviews for a patient can be accessed with the `chart_section_reviews` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    reviews = patient.chart_section_reviews.all()
    ```
If you have a note object, the chart section reviews for that note can be accessed with the `chart_section_reviews` attribute on a `Note` object:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    reviews = note.chart_section_reviews.all()
    ```
##  Filtering 
Chart section reviews can be filtered by any attribute that exists on the model.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.chart_section_review import (
        ChartSectionReview,
        ChartSectionReviewSection,
    )
    # Get all reviews for the conditions section
    condition_reviews = ChartSectionReview.objects.filter(
        section=ChartSectionReviewSection.CONDITIONS
    )
    ```
###  By patient and section 
    ```python
    from canvas_sdk.v1.data.chart_section_review import (
        ChartSectionReview,
        ChartSectionReviewSection,
    )
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    medication_reviews = ChartSectionReview.objects.filter(
        patient=patient,
        section=ChartSectionReviewSection.MEDICATIONS
    )
    ```
###  Committed reviews 
The `committed` method returns chart section reviews that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.chart_section_review import ChartSectionReview
    committed_reviews = ChartSectionReview.objects.committed()
    ```
##  Working with entries 
`entries` is a list of integer `dbid` values identifying the records that were reviewed in the section. Which model those `dbid`s belong to depends on the review's `section`:
`section`| Model(s) referenced by `entries`  
---|---  
`conditions`| [Condition](/sdk/data-condition/) (non-surgical)  
`surgical_history`| [Condition](/sdk/data-condition/) (surgical)  
`medications`| [Medication](/sdk/data-medication/)  
`family_histories`| [FamilyHistory](/sdk/data-family-history/#familyhistory)  
`allergies`| [AllergyIntolerance](/sdk/data-allergy-intolerance/)  
`immunizations`| [Immunization](/sdk/data-immunization/) and [ImmunizationStatement](/sdk/data-immunization/)  
If you only need to **see what was reviewed** , prefer the `content` field: it holds the pre-rendered text of the reviewed records (one line per entry, captured at review time), so it needs no entry resolution and avoids the ambiguity described below.
To work with the **record objects themselves** , filter the corresponding model by `dbid__in=review.entries`. Always scope the query to `review.patient` as well: a `dbid` is unique only within its own table, so scoping by patient avoids matching an unrelated record that happens to share the same integer (this is also why the `immunizations` section, which draws from two models, is resolved against both).
    ```python
    from canvas_sdk.v1.data.allergy_intolerance import AllergyIntolerance
    from canvas_sdk.v1.data.chart_section_review import (
        ChartSectionReview,
        ChartSectionReviewSection,
    )
    from canvas_sdk.v1.data.condition import Condition
    from canvas_sdk.v1.data.family_history import FamilyHistory
    from canvas_sdk.v1.data.immunization import Immunization, ImmunizationStatement
    from canvas_sdk.v1.data.medication import Medication
    review = ChartSectionReview.objects.get(id="b5a0c1d2-e3f4-5678-9abc-def012345678")
    if review.section == ChartSectionReviewSection.CONDITIONS:
        records = Condition.objects.filter(
            patient=review.patient, dbid__in=review.entries, surgical=False
        )
    elif review.section == ChartSectionReviewSection.SURGICAL_HISTORY:
        records = Condition.objects.filter(
            patient=review.patient, dbid__in=review.entries, surgical=True
        )
    elif review.section == ChartSectionReviewSection.MEDICATIONS:
        records = Medication.objects.filter(patient=review.patient, dbid__in=review.entries)
    elif review.section == ChartSectionReviewSection.FAMILY_HISTORIES:
        records = FamilyHistory.objects.filter(patient=review.patient, dbid__in=review.entries)
    elif review.section == ChartSectionReviewSection.ALLERGIES:
        records = AllergyIntolerance.objects.filter(patient=review.patient, dbid__in=review.entries)
    elif review.section == ChartSectionReviewSection.IMMUNIZATIONS:
        # entries may reference either model, so resolve against both.
        records = [
            *Immunization.objects.filter(patient=review.patient, dbid__in=review.entries),
            *ImmunizationStatement.objects.filter(patient=review.patient, dbid__in=review.entries),
        ]
    ```
> **Note on the`immunizations` section:** `entries` stores bare `dbid` integers with no indication of which model each one came from. Because `Immunization` and `ImmunizationStatement` are separate tables with independent `dbid` sequences, the same integer can be a valid `dbid` in both. If a patient has an `Immunization` and an `ImmunizationStatement` that share a `dbid` and only one was reviewed, resolving against both models (as above) will return both records — there is no way to disambiguate them from `entries` alone. Treat the immunizations result as a best-effort superset, not an exact match. If you only need to know what was reviewed, use `content` instead: it captured the rendered text of the actual reviewed items at review time.

# Claim

Source: https://docs.canvasmedical.com/sdk/data-claim/

##  Introduction 
This module defines the data models used to manage healthcare claim workflows.
##  Basic usage 
To retrieve a claim by its identifier:
    ```python
    from canvas_sdk.v1.data.claim import Claim
    claim = Claim.objects.get(id="9d2e0f58-338b-11ec-8d3d-0242ac130003")
    ```
To access diagnosis codes for a claim:
    ```python
    from canvas_sdk.v1.data.claim import Claim
    claim = Claim.objects.get(id="9d2e0f58-338b-11ec-8d3d-0242ac130003")
    diagnosis_codes = claim.diagnosis_codes.all().order_by("rank")
    for diagnosis in diagnosis_codes:
        print(f"Rank {diagnosis.rank}: {diagnosis.code} - {diagnosis.display}")
    ```
To access banner alerts for a claim:
    ```python
    from canvas_sdk.v1.data.claim import Claim
    claim = Claim.objects.get(id="9d2e0f58-338b-11ec-8d3d-0242ac130003")
    active_alerts = claim.banner_alerts.filter(status="active")
    for alert in active_alerts:
        print(f"[{alert.intent}] {alert.narrative}")
    ```
##  Filtering 
    ```python
    from canvas_sdk.v1.data.claim import Claim
    # Active claims only
    active_claims = Claim.objects.active()
    ```
##  Attributes 
###  Claim 
Represents a complete healthcare claim. Claim belongs to a Note and has a one-to-one relationship with a ClaimPatient.

**Computed Properties** :
  - `total_charges`: Total charges for active line items
  - `total_paid`: Sum of paid amounts from postings
  - `total_adjusted`: Sum of adjustments and transfers
  - `balance`: Remaining balance (coverage + patient)
  - `total_patient_paid`: Paid amount by the patient
  - `total_payer_paid`: Paid amount by coverages
**Helpful Methods** :
  - `get_coverage_by_payer_id(payer_id: str, subscriber_number: str | None = None)`: Finds the active coverage associated with a payer_id. Optionally checks if the subscriber_number matches, which will choose the correct coverage in the case where a patient has two coverages with the same payer_id.
###  ClaimSupervisingProvider

# Command

Source: https://docs.canvasmedical.com/sdk/data-command/

##  Introduction 
The `Command` model represents a [command](/sdk/commands/) in a note.
##  Basic usage 
To get a command by identifier, use the `get` method on the `Command` model manager:
    ```python
    from canvas_sdk.v1.data.command import Command
    command = Command.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
##  Filtering 
Commands can be filtered by any attribute that exists on the model.
Filtering for commands is done with the `filter` method on the `Command` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.command import Command
    commands = Command.objects.filter(state="committed")
    ```
##  Command types and data 
When events are fired as part of [Command Lifecycle Events](/sdk/events/#command-lifecycle-events), the `self.target` value that is available within a plugin will contain the `id` value of the command. For example:
    ```python
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from logger import log
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.REASON_FOR_VISIT_COMMAND__POST_UPDATE),
        ]
        def compute(self) -> list[Effect]:
            log.info(self.target) # logs the Command id
    ```
Using this value, the `Command` model can be queried to fetch additional data about the command. Two main fields to pay attention to here are the `schema_key` and `data` fields. The `schema_key` field contains the type of the command, while the `data` field contains a JSON object with command data as key/value pairs:
    ```python
    import json
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.command import Command
    from logger import log
    class MyHandler(BaseHandler):
        def compute(self) -> list[Effect]:
            command_instance = Command.objects.get(id=self.target)
            log.info(command_instance.schema_key)
            log.info(json.dumps(command_instance.data, indent=2))
    ```
For example, for a _Reason For Visit_ command, the preceding code would log the following lines:
    ```sh
    reasonForVisit
    {
      "coding": {
        "text": "Accident-prone",
        "extra": null,
        "value": "165002",
        "disabled": false,
        "annotations": null,
        "description": null
      },
      "comment": "Patient would like to discuss condition."
    }
    ```
The following table shows the different command `schema_key` values with links to their respective [Command Modules](/sdk/commands). The attributes shown in each corresponding entry contain the structure that will appear in the `data` JSON field of each `Command`.

**PLEASE NOTE** the Commands Module is under development and Canvas is working to migrate all commands to be available. This means that some commands are not able to emit events available in plugins, and historical commands created prior to their Commands Module availability may not be able to be queried using the data module. [This product updates table](/product-updates/commands-module/) shows the commands and their release statuses. If a command in a chart is not available by querying the `Command` data model, the data is still available to be queried using corresponding data models (i.e. [Questionnaire](/sdk/data-questionnaire/), [ImagingOrder](/sdk/data-imaging/), etc.).

###  CommandMetadata 
`CommandMetadata` stores custom key-value pairs associated with a command. Metadata can be upserted using the `upsert_metadata` method on any command effect class — see [CommandMetadata Effect](/sdk/effect-command-metadata/) for full details.
    ```python
    from canvas_sdk.v1.data.command import CommandMetadata
    # Get all metadata for a command

# CompoundMedication

Source: https://docs.canvasmedical.com/sdk/data-compound-medication/

##  Introduction 
The `CompoundMedication` model represents a compound medication formulation that can be prescribed to patients. Compound medications are customized medications mixed or prepared by a compounding pharmacy according to a prescription.
##  Basic usage 
To get a compound medication by identifier, use the `get` method on the `CompoundMedication` model manager:
    ```python
    from canvas_sdk.v1.data.compound_medication import CompoundMedication
    compound_medication = CompoundMedication.objects.get(id="123")
    ```
##  Filtering 
Compound medications can be filtered by any attribute that exists on the model.
Filtering for compound medications is done with the `filter` method on the `CompoundMedication` model manager.
###  By attribute 
Specify attributes with `filter` to filter by those attributes:
    ```python
    from canvas_sdk.v1.data.compound_medication import CompoundMedication
    # Get all active compound medications
    active_medications = CompoundMedication.objects.filter(active=True)
    # Get compound medications by formulation
    compound_medications = CompoundMedication.objects.filter(formulation="Testosterone 200mg/mL in Grapeseed Oil")
    # Get all Schedule II controlled substances
    schedule_ii_medications = CompoundMedication.objects.filter(controlled_substance="II")
    # Get compound medications by potency unit
    tablet_medications = CompoundMedication.objects.filter(potency_unit_code="C48542")
    ```
###  Multiple filters

# Condition

Source: https://docs.canvasmedical.com/sdk/data-condition/

##  Introduction 
The `Condition` model represents a clinical condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern.
##  Basic usage 
To get a condition by identifier, use the `get` method on the `Condition` model manager:
    ```python
    from canvas_sdk.v1.data.condition import Condition
    condition = Condition.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the conditions for a patient can be accessed with the `conditions` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    conditions = patient.conditions.all()
    ```
If you have a patient ID, you can get the conditions for the patient with the `for_patient` method on the `Condition` model manager:
    ```python
    from canvas_sdk.v1.data.condition import Condition
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    condition = Condition.objects.for_patient(patient_id)
    ```
##  Codings 
The codings for a condition can be accessed with the `codings` attribute on an `Condition` object:
    ```python
    from canvas_sdk.v1.data.condition import Condition
    from logger import log
    condition = Condition.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in condition.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Conditions can be filtered by any attribute that exists on the model.
Filtering for conditions is done with the `filter` method on the `Condition` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.condition import Condition
    conditions = Condition.objects.filter(onset_date__gte="2024-10-15")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.condition import Condition
    from canvas_sdk.value_set.v2022.condition import Diabetes
    conditions = Condition.objects.find(Diabetes)
    ```

# ContentType

Source: https://docs.canvasmedical.com/sdk/data-content-type/

##  Introduction 
The `ContentType` model exposes Django content types. Use it to resolve the content type id for a given model, which is required when working with generic relations (such as [document references](/sdk/data-document-reference)) and when generating permalinks.
A content type is identified by two **stable** values — `app_label` and `model` — that are the same on every Canvas instance. Its `dbid` (the content type id) is a per-database auto-increment that **is not stable across environments**. Always resolve the `dbid` at runtime from the `app_label` and `model`; never hardcode a content type id, or it will point at the wrong model in another environment.
##  Basic usage 
To get a content type by its database id, use the `get` method on the `ContentType` model manager:
    ```python
    from canvas_sdk.v1.data import ContentType
    content_type = ContentType.objects.get(dbid=42)
    ```
##  Resolving a content type at runtime 
Because the `dbid` differs per environment, look the content type up by its stable `app_label` and `model`, then read `dbid` from the result:
    ```python
    from canvas_sdk.v1.data import ContentType
    content_type = ContentType.objects.filter(app_label="api", model="note").first()
    if content_type:
        # Resolved for this environment — safe to use for a generic relation or permalink.
        content_type_id = content_type.dbid
    ```
##  Filtering 
Content types can be filtered by any attribute that exists on the model.
Filtering for content types is done with the `filter` method on the `ContentType` model manager.
###  By model 
To find the content type for a specific model, filter by `app_label` and `model`:
    ```python
    from canvas_sdk.v1.data import ContentType
    content_type = ContentType.objects.filter(app_label="api", model="note").first()
    if content_type:
        print(f"Content type id: {content_type.dbid}")
    ```
##  app_label and model for data module models 
Use these stable values to resolve a content type with `ContentType.objects.filter(app_label=..., model=...)`. The `model` value is the lowercased Django model name, and most data module models live under the `api` app. This list is not exhaustive — any model not shown here can be resolved the same way once you know its `app_label` and `model`.

# Coverage

Source: https://docs.canvasmedical.com/sdk/data-coverage/

##  Introduction 
The `Coverage` model represents insurance coverage linked to [Patients](/sdk/data-patient/#patient). Coverages are linked to [Patient](/sdk/data-patient/#patient) instances, as well as `Transactor` instances, which represent the issuer for the corresponding coverage. `Coverage`s also have an associated `EligibilitySummary`, which provides the most up-to-date copay and coinsurance values.
Coverages can also be linked to a [`Snapshot`](/sdk/data-snapshot/#snapshot), which provides access to insurance card images captured via the Canvas iOS application or uploaded through the coverages modal.
##  Usage 
The `Coverage` model can be used to find all of the coverages defined in a Canvas instance, whether overall or for a particular patient. For example, to find all of the current coverages for a patient, the `Patient.coverages` method can be used:
    ```python
    >>> import arrow
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    >>> patient_1_current_coverages = patient_1.coverages.filter(coverage_end_date__gt=arrow.now().date().isoformat())
    >>> print([coverage.issuer.name for coverage in patient_1_current_coverages])
    ['AVALON HEALTHCARE SOLUTIONS CAPITAL BLUE CROSS']
    ```
Alternatively, to find all of the `Coverage` instances issed by a particular issuer/transactor, the `Transactor` model can be queried:
    ```python
    >>> from canvas_sdk.v1.data.coverage import Coverage, Transactor
    >>> transactor_1 = Transactor.objects.get(payer_id="AVA03")
    >>> transactor_coverages = Coverage.objects.filter(issuer=transactor_1)
    >>> print(transactor_coverages)
    <QuerySet [<Coverage: id=89793979-dbff-4a53-b928-75db973c2bdc>, <Coverage: id=423c0f77-8083-4cc1-8e29-2c7d348281e4>]>
    >>>
    ```
Find the latest eligibility summary for a patient:
    ```python
        from canvas_sdk.v1.data.coverage import Coverage, EligibilitySummary
        coverage = Coverage.objects.get(id="a74592ae-8a6c-4d0e-be07-99d3fb3713d1")
        elig_summary_from_model = EligibilitySummary.objects.filter(coverage=coverage).first()
        elig_summary_from_cvg = coverage.eligibility_summary
        if elig_summary_from_model:
            print(elig_summary_from_model.copay_cents, elig_summary_from_model.coinsurance) # 1000 5
        if elig_summary_from_cvg:
            print(elig_summary_from_cvg.copay_cents, elig_summary_from_cvg.coinsurance) # 1000 5
    ```
Access insurance card images through the coverage's snapshot:
    ```python
    from canvas_sdk.v1.data.coverage import Coverage
    coverage = Coverage.objects.get(id="a74592ae-8a6c-4d0e-be07-99d3fb3713d1")
    if coverage.snapshot:
        for image in coverage.snapshot.images.all():
            print(image.image_url)  # Presigned S3 URL for the insurance card image
    ```
##  Eligibility status 
`Coverage.eligibility_status` returns the [`EligibilityResponseStatus`](/sdk/data-eligibility-response/#eligibilityresponsestatus) of the coverage's most recent [`EligibilityResponse`](/sdk/data-eligibility-response/#eligibilityresponse). It returns `UNKNOWN` when the coverage has never been checked (it has no eligibility responses):
    ```python
    from canvas_sdk.v1.data.coverage import Coverage
    from canvas_sdk.v1.data.eligibility_response import EligibilityResponseStatus
    coverage = Coverage.objects.get(id="a74592ae-8a6c-4d0e-be07-99d3fb3713d1")
    if coverage.eligibility_status == EligibilityResponseStatus.ACTIVE:
        print("Coverage is active")
    ```
`Coverage.eligibility_status` returns `NOT_APPLICABLE` for a self-pay coverage, meaning one whose issuer has a `payer_id` of `PATIENT`. It resolves this case before consulting the stored eligibility responses, so a stale `FAILED` response left on a self-pay coverage is never surfaced.
That is also what `Transactor.supports_eligibility_check` reports: it is `False` for the self-pay payer, whose `payer_id` is `PATIENT`, and `True` for every other issuer.
Because it is computed on each access rather than stored, `eligibility_status` cannot be used in `filter()`. Filter on the coverage's [eligibility responses](/sdk/data-eligibility-response/#eligibilityresponse) instead, or read the property once you have the coverage in hand.
A single [`EligibilityResponse.status`](/sdk/data-eligibility-response/#eligibilityresponse), by contrast, never resolves to `UNKNOWN` — that value belongs to the coverage, which has no response to defer to. To react to eligibility changes rather than poll for them, subscribe to the [eligibility response events](/sdk/events/#eligibility-responses). Those fire only when a response is saved, so a coverage that has never been checked emits no event at all: a plugin that has to catch never-verified coverages should read `eligibility_status` rather than rely on the events alone.
##  Filtering 
The `filter` method can be used to filter by desired attributes. The following examples show commonly used operations to filter coverage data:
**Show a Patient's Coverages in order of Rank (Primary, Secondary, etc.)**
    ```python
    >>> from canvas_sdk.v1.data.patient import Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> patient_coverages = patient_1.coverages.all().order_by("coverage_rank")
    >>> print([(coverage.issuer.name, coverage.coverage_rank,) for coverage in patient_coverages])
    [('AVALON HEALTHCARE SOLUTIONS CAPITAL BLUE CROSS', 1), ('Blue Cross Blue Shield of Arizona Advantage', 2)]
    ```
**Find All Expired Coverages**
    ```python
    >>> import arrow
    >>> from canvas_sdk.v1.data.coverage import Coverage
    >>> expired_coverages = Coverage.objects.filter(coverage_end_date__lt=arrow.now().date().isoformat())
    >>> print([f"{coverage.issuer.name} expired {coverage.coverage_end_date.isoformat()}" for coverage in expired_coverages])
    ['Blue Cross Blue Shield of Arizona Advantage expired 2025-01-10']
    ```

# DetectedIssue

Source: https://docs.canvasmedical.com/sdk/data-detected-issue/

##  Introduction 
The `DetectedIssue` model represents an actual or potential clinical issue with or between one or more active or proposed clinical actions for a patient.
##  Basic usage 
To get a detected issue by identifier, use the `get` method on the `DetectedIssue` model manager:
    ```python
    from canvas_sdk.v1.data.detected_issue import DetectedIssue
    detected_issue = DetectedIssue.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the detected issues for a patient can be accessed with the `detected_issues` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    detected_issues = patient.detected_issues.all()
    ```
##  Evidence 
The codings for the evidence of a detected issue can be accessed with the `evidence` attribute on a `DetectedIssue` object:
    ```python
    from canvas_sdk.v1.data.detected_issue import DetectedIssue
    from logger import log
    detected_issue = DetectedIssue.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in detected_issue.evidence.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Detected issues can be filtered by any attribute that exists on the model.
Filtering for detected issues is done with the `filter` method on the `DetectedIssue` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.detected_issue import DetectedIssue
    detected_issues = DetectedIssue.objects.filter(status="active")
    ```
###  Committed detected issues 
The `committed` method returns detected issues that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.detected_issue import DetectedIssue
    committed_detected_issues = DetectedIssue.objects.committed()
    ```

# Device

Source: https://docs.canvasmedical.com/sdk/data-device/

##  Introduction 
The `Device` model represents a type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.
##  Basic usage 
To get a device by identifier, use the `get` method on the `Device` model manager:
    ```python
    from canvas_sdk.v1.data.device import Device
    device = Device.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the devices for a patient can be accessed with the `devices` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    devices = patient.devices.all()
    ```
##  Filtering 
Devices can be filtered by any attribute that exists on the model.
Filtering for devices is done with the `filter` method on the `Device` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.device import Device
    devices = Device.objects.filter(manufacturer="ACME Biomedical", lot_number="M320")
    ```
###  Committed devices 
The `committed` method returns devices that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.device import Device
    committed_devices = Device.objects.committed()
    ```

# DiagnosticView

Source: https://docs.canvasmedical.com/sdk/data-diagnostic-view/

##  Introduction 
The `DiagnosticView` model represents a saved combination of lab tests and questionnaire codes configured on your instance. A diagnostic view has no patient of its own — it is a reusable definition. When a diagnostic view is embedded in a note with the [Reference](/sdk/commands/#reference) command, Canvas renders that patient's results for the view's codes as a timeseries.
Diagnostic views are configured by an administrator, so the set available to a plugin is whatever your instance has defined.
##  Basic usage 
To get a diagnostic view by identifier, use the `get` method on the `DiagnosticView` model manager:
    ```python
    from canvas_sdk.v1.data import DiagnosticView
    view = DiagnosticView.objects.get(id="dca3a3c5-0a8e-4f7b-9c6a-1b9bf3a6e5e0")
    ```
To list every diagnostic view on the instance:
    ```python
    from canvas_sdk.v1.data import DiagnosticView
    views = DiagnosticView.objects.all()
    ```
##  Filtering 
Diagnostic views can be filtered by any attribute that exists on the model.
###  By name 
Names are set by whoever configured the view, so match on the exact name you expect and handle the case where it is absent:
    ```python
    from canvas_sdk.v1.data import DiagnosticView
    a1c_view = DiagnosticView.objects.filter(name="Hemoglobin A1c").first()
    ```
###  By search tag 
`tags` is a single free-text string of search terms, not a list, so use a substring match:
    ```python
    from canvas_sdk.v1.data import DiagnosticView
    diabetes_views = DiagnosticView.objects.filter(tags__icontains="diabetes")
    ```
##  Embedding a view in a note 
Pass the view's `id` to the [Reference](/sdk/commands/#reference) command:
    ```python
    from canvas_sdk.commands import ReferenceCommand
    from canvas_sdk.v1.data import DiagnosticView
    def compute():
        a1c_view = DiagnosticView.objects.filter(name="Hemoglobin A1c").first()
        if not a1c_view:
            return []
        reference = ReferenceCommand(
            note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
            diagnostic_view_id=a1c_view.id,
        )
        return [reference.originate(commit=True)]
    ```
##  Attributes 
###  DiagnosticView 
Field Name| Type  
---|---  
id| UUID  
dbid| Integer  
created| DateTime  
modified| DateTime  
name| String (up to 100 characters)  
tags| String (up to 500 characters; free-text search terms)  
originator| [CanvasUser](/sdk/data-canvasuser)

# DocumentReference

Source: https://docs.canvasmedical.com/sdk/data-document-reference/

#  DocumentReference 
The `DocumentReference` model represents references to documents stored in Canvas, such as uploaded PDFs, scanned files, and other clinical documents. Each document reference can link to a file stored in S3 and provides secure access via presigned URLs.
##  Basic Usage 
    ```python
    from canvas_sdk.v1.data import DocumentReference
    # Get a specific document reference
    doc_ref = DocumentReference.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    # Get all document references
    all_docs = DocumentReference.objects.all()
    ```
##  Filtering 
###  By patient 
    ```python
    from canvas_sdk.v1.data import DocumentReference
    patient_docs = DocumentReference.objects.for_patient("b80b1cdc2e6a4aca90ccebc02e683f35")
    ```
###  By status 
    ```python
    from canvas_sdk.v1.data import DocumentReference, DocumentReferenceStatus
    current_docs = DocumentReference.objects.filter(status=DocumentReferenceStatus.CURRENT)
    ```
###  By category or type 
    ```python
    from canvas_sdk.v1.data import DocumentReference
    docs = DocumentReference.objects.filter(category__code="clinical-note")
    ```
##  Accessing Document Files 
The `document_url` property returns a presigned S3 URL for securely accessing the document file. If no S3 file is present, it falls back to the `document_absolute_url` field.
    ```python
    from canvas_sdk.v1.data import DocumentReference
    doc_ref = DocumentReference.objects.exclude(document="").first()
    # Returns a presigned S3 URL (valid for 1 hour)
    url = doc_ref.document_url
    ```
##  Attributes 
###  DocumentReference 
Field Name| Type  
---|---

object_id| Integer (the related object's `dbid`)  
related_object| Model (property) — the SDK object the document is attached to, or `None`  
document_url| String (property) — presigned S3 URL or absolute URL  
###  DocumentReferenceCoding 
A coding entry representing the type of a document reference.
Field Name| Type  
---|---  
dbid| Integer  
system| String  
version| String  
code| String  
display| String  
user_selected| Boolean  
###  DocumentReferenceCategory 
A coding entry representing the category of a document reference.
Field Name| Type  
---|---  
dbid| Integer  
system| String  
version| String  
code| String  
display| String  
user_selected| Boolean  
###  DocumentReferenceStatus 
An enum representing the status of a document reference.
Member| Value| Description  
---|---|---  
`CURRENT`| `current`| Current  
`SUPERSEDED`| `superseded`| Superseded  
`ENTERED_IN_ERROR`| `entered-in-error`| Entered in Error  
##  The related object 
Most document references point back at the record they were generated from — a lab report, a letter, a locked-note PDF, a patient statement, and so on. `content_type` and `object_id` form that generic link: `content_type` identifies the linked model by its stable `app_label` and lowercased `model` name, and `object_id` is that record's `dbid`.
The `related_object` property resolves the link for you, returning the corresponding SDK data model instance:
    ```python
    from canvas_sdk.v1.data import DocumentReference
    doc_ref = DocumentReference.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    # The SDK object this document is attached to (a LabReport, Letter, ImagingReport, ...), or None.
    source = doc_ref.related_object
    ```
`related_object` returns `None` when the document has no related object (`content_type` or `object_id` is unset) or when the linked content type has no SDK data model equivalent. The content types it resolves today:
`app_label` / `model`| SDK data model  
---|---  
`api` / `labreport`| [LabReport](/sdk/data-labs/#labreport)  
`api` / `imagingreport`| [ImagingReport](/sdk/data-imaging/#imagingreport)  
`api` / `letter`| [Letter](/sdk/data-letter/#letter)  
`api` / `notestatechangeevent`| [NoteStateChangeEvent](/sdk/data-note/#notestatechangeevent)  
`api` / `uncategorizedclinicaldocument`| [UncategorizedClinicalDocument](/sdk/data-uncategorized-clinical-document/#uncategorizedclinicaldocument)  
`api` / `referralreport`| [ReferralReport](/sdk/data-referral/#referralreport)  
`api` / `educationalmaterial`| [EducationalMaterial](/sdk/data-educational-material/#educationalmaterial)  
`api` / `patientadministrativedocument`| [PatientAdministrativeDocument](/sdk/data-patient-administrative-document/#patientadministrativedocument)  
`quality_and_revenue` / `invoicefull`| [Invoice](/sdk/data-invoice/#invoice)  
To go the other way — find every document reference for a given source type — resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` (never hardcode the per-environment `dbid`) and filter on it:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference
    content_type = ContentType.objects.filter(
        app_label="api", model="patientadministrativedocument"
    ).first()
    references = DocumentReference.objects.filter(content_type=content_type)
    ```

# Document Review Delegation

Source: https://docs.canvasmedical.com/sdk/data-document-review-delegation/

##  Introduction 
The `DocumentReviewDelegation` model records a hand-off of a document review from one staff member to another staff member or team. When a reviewer delegates an uncategorized clinical document, Canvas stores who delegated it, who received it, the original owner, whether the recipient may apply the owner's signature, and any instructions.
Delegations are an append-only log: a document has at most one **active** delegation at a time (`is_active`). Delegation is A↔B only — an owner delegates a document out, and the recipient may only route it back — so `on_behalf_of` always identifies the original owner and, when `signature_consent` is set, the staff member whose signature the recipient may apply while annotating the document.
##  Basic usage 
To get a delegation by identifier, use the `get` method on the `DocumentReviewDelegation` model manager:
    ```python
    from canvas_sdk.v1.data import DocumentReviewDelegation
    delegation = DocumentReviewDelegation.objects.get(id="b5a0c1d2-e3f4-5678-9abc-def012345678")
    ```
If you have an [UncategorizedClinicalDocument](/sdk/data-uncategorized-clinical-document/), its delegations are available through the `delegations` and `active_delegation` accessors:
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    document = UncategorizedClinicalDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    # The full delegation history, oldest first.
    history = document.delegations
    # The current active delegation, or None when the document is with its owner.
    current = document.active_delegation
    if current and current.signature_consent:
        signer = current.on_behalf_of  # whose signature the recipient may apply
    ```
##  Filtering 
Delegations can be filtered by any attribute that exists on the model.
###  Active delegations 
    ```python
    from canvas_sdk.v1.data import DocumentReviewDelegation
    active = DocumentReviewDelegation.objects.filter(is_active=True)
    ```
###  Delegations that granted signature consent 
    ```python
    from canvas_sdk.v1.data import DocumentReviewDelegation
    with_consent = DocumentReviewDelegation.objects.filter(is_active=True, signature_consent=True)
    ```
##  Route-back 
Use the `is_route_back` property to tell whether an active delegation returned the document to its owner (as opposed to delegating it away):
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    document = UncategorizedClinicalDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    delegation = document.active_delegation
    if delegation and delegation.is_route_back:
        ...  # the document is back with its owner
    ```
##  Attributes 
###  DocumentReviewDelegation 
Field Name| Type  
---|---  
id| UUID  
dbid| Integer  
created| DateTime  
modified| DateTime  
content_type| [ContentType](/sdk/data-content-type/) (the delegated document's type)  
object_id| Integer (the delegated document's `dbid`)  
delegated_by| [Staff](/sdk/data-staff/#staff) (who handed the document off)  
delegated_to_staff| [Staff](/sdk/data-staff/#staff) (recipient, if delegated to a person)  
delegated_to_team| [Team](/sdk/data-team/#team) (recipient, if delegated to a team)  
on_behalf_of| [Staff](/sdk/data-staff/#staff) (the original owner)  
signature_consent| Boolean (may the recipient apply the owner's signature)  
comment| String (instructions for the recipient)  
is_active| Boolean (the current delegation for the document)  
##  The delegated document 
`content_type` and `object_id` form a generic link to the document whose review was delegated: `content_type` identifies the linked model, and `object_id` is that record's `dbid`. Review delegation is currently supported only for [UncategorizedClinicalDocument](/sdk/data-uncategorized-clinical-document/) records, so `content_type` always resolves to that model and `object_id` is the document's `dbid`. The generic relation leaves room for additional document types in the future.
The most direct way to work with a document's delegations is from the document itself, through its `delegations` and `active_delegation` accessors:
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    document = UncategorizedClinicalDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    current = document.active_delegation   # the active DocumentReviewDelegation, or None
    history = document.delegations         # every delegation hop recorded for the document
    ```
To go the other way — from a delegation to the document it points at — read `content_type` to learn which model `object_id` refers to, then resolve it. A [ContentType](/sdk/data-content-type/) is identified by its stable `app_label` and `model` (the lowercased model name), so branch on those rather than on the per-environment `dbid`. This keeps working if more document types become delegatable later:
    ```python
    from canvas_sdk.v1.data import DocumentReviewDelegation, UncategorizedClinicalDocument
    delegation = DocumentReviewDelegation.objects.get(id="b3e6f74c-2a1b-4c8d-9f2e-31842ae7d3b9")
    content_type = delegation.content_type
    # Today content_type is always api / uncategorizedclinicaldocument; object_id is its dbid.
    if content_type.app_label == "api" and content_type.model == "uncategorizedclinicaldocument":
        document = UncategorizedClinicalDocument.objects.get(dbid=delegation.object_id)
    ```
You can also use `content_type` to find every delegation for a given document type. Resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the `dbid`, which differs per environment:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReviewDelegation
    document_ct = ContentType.objects.filter(app_label="api", model="uncategorizedclinicaldocument").first()
    delegations = DocumentReviewDelegation.objects.filter(content_type=document_ct)
    ```
Exactly one of `delegated_to_staff` / `delegated_to_team` is set on a delegation.

# EducationalMaterial

Source: https://docs.canvasmedical.com/sdk/data-educational-material/

##  Introduction 
The `EducationalMaterial` model represents patient educational material recorded on a note through the Educational Material command — the selected article, its title and abstract, and the languages it is available in.
Records are returned regardless of command state, so staged commands are included; use `committed()` to limit results to committed commands.
##  Basic Usage 
`EducationalMaterial` records can be retrieved by their UUID `id`, their integer `dbid`, or through a patient.
    ```python
    from canvas_sdk.v1.data import EducationalMaterial
    # Get all educational material records
    materials = EducationalMaterial.objects.all()
    # Get a specific record by its UUID id
    material = EducationalMaterial.objects.get(id="c9a7b1e2-d4f3-4e6a-8b5c-0d1e2f3a4b5c")
    ```
If you have a `Patient` object, its educational material records can be accessed with the `education_material` reverse relation:
    ```python
    from canvas_sdk.v1.data import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    materials = patient.education_material.all()
    ```
##  Filtering 
###  By attribute 
    ```python
    from canvas_sdk.v1.data import EducationalMaterial
    materials = EducationalMaterial.objects.filter(selected_language="en-us")
    ```
###  Committed records 
The `committed` method returns records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import EducationalMaterial
    committed = EducationalMaterial.objects.committed()
    ```
##  Accessing the article PDF 
`EducationalMaterial` holds the article's metadata — its title, abstract, and languages — not the article file itself. When the command is committed, Canvas renders the article to a PDF and attaches it to a [DocumentReference](/sdk/data-document-reference/) with the LOINC type `34895-3` (Education note).
To read a patient's education note PDFs, filter `DocumentReference` by that type and use its `document_url`:
    ```python
    from canvas_sdk.v1.data import DocumentReference
    education_notes = DocumentReference.objects.for_patient(
        "1eed3ea2a8d546a1b681a2a45de1d790"
    ).filter(type__code="34895-3")
    for note in education_notes:
        url = note.document_url
    ```
To resolve the PDF for one specific record, filter on the document's [related object](/sdk/data-document-reference/#the-related-object) instead. Resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the material's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, EducationalMaterial
    material = EducationalMaterial.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    content_type = ContentType.objects.filter(
        app_label="api", model="educationalmaterial"
    ).first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=material.dbid
    ).first()

# EligibilityResponse

Source: https://docs.canvasmedical.com/sdk/data-eligibility-response/

##  Introduction 
The `EligibilityResponse` model represents a coverage eligibility (271) response returned by a payer for a patient's `Coverage`, along with the originating `EligibilityRequest` (270). An `EligibilityResponse` also derives a check `status` (Active, Inactive, or Failed) from the payer's response.
##  Basic usage 
To get an eligibility response by identifier, use the `get` method on the `EligibilityResponse` model manager:
    ```python
    from canvas_sdk.v1.data.eligibility_response import EligibilityResponse
    response = EligibilityResponse.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
Eligibility requests and responses are linked to a `Coverage`. From a coverage object, use the `requests` and `eligibility_responses` attributes:
    ```python
    from canvas_sdk.v1.data.coverage import Coverage
    coverage = Coverage.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    requests = coverage.requests.all()
    responses = coverage.eligibility_responses.all()
    ```
##  Eligibility status 
`EligibilityResponse.status` returns an `EligibilityResponseStatus` derived from the payer's response — `FAILED` when the check errored, `INACTIVE` when the payer reports an inactive benefit section, otherwise `ACTIVE`:
    ```python
    from canvas_sdk.v1.data.coverage import Coverage
    from canvas_sdk.v1.data.eligibility_response import EligibilityResponseStatus
    coverage = Coverage.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    response = coverage.eligibility_responses.order_by("created").last()
    is_active = response is not None and response.status == EligibilityResponseStatus.ACTIVE
    ```
A coverage with no eligibility responses (an empty `coverage.eligibility_responses` queryset) has not been verified.
`NOT_APPLICABLE`, like `UNKNOWN`, is a value returned by [`Coverage.eligibility_status`](/sdk/data-coverage/#eligibility-status), never by an individual `EligibilityResponse.status`. A single response only ever resolves to `FAILED`, `INACTIVE`, or `ACTIVE`.
##  Attributes

x12_response| String  
parsed_x12_response| JSON  
status| EligibilityResponseStatus (computed)  
eligibility_or_benefit_information| List (computed)  
`status` and `eligibility_or_benefit_information` are computed from `errors` and `parsed_x12_response` rather than stored, so neither can be used in `filter()`. To select responses by outcome, filter on the columns they derive from — a failed check is one with a non-empty `errors`:
    ```python
    from canvas_sdk.v1.data.eligibility_response import EligibilityResponse
    failed = EligibilityResponse.objects.exclude(errors=None).exclude(errors=[])
    ```

# Encounter

Source: https://docs.canvasmedical.com/sdk/data-encounter/

##  Introduction 
The `Encounter` model represents a patient encounter connected to a Note in Canvas.
##  Basic usage 
To get an encounter by identifier, use the `get` method on the `Encounter` model manager:
    ```python
    from canvas_sdk.v1.data import Encounter
    encounter = Encounter.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
To get an encounter from a note, use the `encounter` attribute on the `Note` object:
    ```python
    from canvas_sdk.v1.data import Note
    note = Note.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    encounter = note.encounter
    ```
Keep in mind that not all notes have an associated encounter, so sometimes `note.encounter` will be `None`.
Similary, you can get a note from an `Encounter` object by using the `note` attribute:
    ```python
    from canvas_sdk.v1.data import Encounter
    encounter = Encounter.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    note = encounter.note
    ```
All encounters will have an associated note, which means `encounter.note` will never be `None`.
##  Filtering 
Encounters can be filtered by any attribute that exists on the model.
Filtering for encounters is done with the `filter` method on the `Encounter` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.encounter import Encounter, EncounterState
    encounters = Encounter.objects.filter(state=EncounterState.CONCLUDED)
    ```

# ExternalEvent

Source: https://docs.canvasmedical.com/sdk/data-external-event/

##  Introduction 
The `ExternalEvent` and `ExternalVisit` models represent clinical events from external data sources such as ADT (Admission, Discharge, Transfer) feeds. These models enable tracking of patient encounters that occur outside of Canvas, such as hospital admissions, emergency room visits, or transfers between facilities.
An `ExternalVisit` groups related events for a single patient visit, while `ExternalEvent` represents individual events within that visit (e.g., admission, discharge, transfer).
##  Basic usage 
To get an external event by identifier, use the `get` method on the `ExternalEvent` model manager:
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent
    event = ExternalEvent.objects.get(id="b4f8c3a1-2d5e-4f6a-8b9c-1a2b3c4d5e6f")
    ```
To get an external visit:
    ```python
    from canvas_sdk.v1.data.external_event import ExternalVisit
    visit = ExternalVisit.objects.get(id="a1b2c3d4-5e6f-7a8b-9c0d-1e2f3a4b5c6d")
    ```
###  Accessing related models 
If you have an external event, you can access the associated visit and patient:
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent
    event = ExternalEvent.objects.get(id="b4f8c3a1-2d5e-4f6a-8b9c-1a2b3c4d5e6f")
    # Access the parent visit
    visit = event.external_visit
    # Access the patient
    patient = event.patient
    ```
If you have an external visit, you can access all events within that visit:
    ```python
    from canvas_sdk.v1.data.external_event import ExternalVisit
    visit = ExternalVisit.objects.get(id="a1b2c3d4-5e6f-7a8b-9c0d-1e2f3a4b5c6d")
    # Get all events in this visit
    events = visit.visit_events.all()
    ```
If you have a patient object, you can access their external events and visits:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    # Get all external events for this patient
    events = patient.patient_events.all()
    # Get all external visits for this patient
    visits = patient.patient_visits.all()
    ```
##  Filtering 
External events and visits can be filtered by any attribute that exists on the model.
###  By patient 
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent, ExternalVisit
    # Get all events for a specific patient
    events = ExternalEvent.objects.filter(patient__id="1eed3ea2a8d546a1b681a2a45de1d790")
    # Get all visits for a specific patient
    visits = ExternalVisit.objects.filter(patient__id="1eed3ea2a8d546a1b681a2a45de1d790")
    ```
###  By event type 
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent
    # Get all admission events
    admissions = ExternalEvent.objects.filter(event_type="ADT^A01")
    # Get all discharge events
    discharges = ExternalEvent.objects.filter(event_type="ADT^A03")
    ```
###  By cancelled status 
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent
    # Get all non-cancelled events
    active_events = ExternalEvent.objects.filter(event_cancelation_datetime__isnull=True)
    # Get all cancelled events
    cancelled_events = ExternalEvent.objects.filter(event_cancelation_datetime__isnull=False)
    ```
###  By visit identifier 
    ```python
    from canvas_sdk.v1.data.external_event import ExternalVisit
    visit = ExternalVisit.objects.get(visit_identifier="VISIT-12345")
    ```
###  By facility 
    ```python
    from canvas_sdk.v1.data.external_event import ExternalVisit
    visits = ExternalVisit.objects.filter(facility_name="General Hospital")
    ```
##  Attributes 
###  ExternalEvent

##  Common Event Types 
External events typically use HL7 ADT event types:
Event Type| Description  
---|---  
ADT^A01| Admit/Visit Notification  
ADT^A02| Transfer a Patient  
ADT^A03| Discharge/End Visit  
ADT^A04| Register a Patient  
ADT^A08| Update Patient Information  
ADT^A11| Cancel Admit/Visit Notification  
ADT^A12| Cancel Transfer  
ADT^A13| Cancel Discharge/End Visit  
    ```python
    from canvas_sdk.v1.data.external_event import ExternalEvent
    from logger import log
    # Get recent events for a patient and log their types
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    events = ExternalEvent.objects.filter(patient__id=patient_id).order_by("-event_datetime")[:10]
    for event in events:
        status = "CANCELLED" if event.cancelled else "ACTIVE"
        log.info(f"Event: {event.event_type} at {event.event_datetime} [{status}]")
    ```

# Facility

Source: https://docs.canvasmedical.com/sdk/data-facility/

##  Introduction 
The `Facility` object represents a healthcare facility associated with patients within Canvas. Facilities can include hospitals, clinics, or other healthcare institutions where patients receive care. This object contains essential information about the facility, such as its address, contact details, and operational status.
##  Basic Usage 
To get a facility by identifier, use the `get` method on the `Facility` model manager:
    ```python
    from canvas_sdk.v1.data.facility import Facility
    facility = Facility.objects.get(id="34b50dfa-1b3e-4dc2-a11d-41b3115c29f3")
    ```
##  Filtering 
Facilities can be filtered by any attribute that exists on the model.
Filtering for facilities is done with the `filter` method on the `Facility` model manager.
##  Attributes 
Specify attributes with `filter` to filter by those attributes:
    ```python
    from canvas_sdk.v1.data.facility import Facility
    facilities = Facility.objects.filter(name="General Hospital", city="Metropolis")
    ```
###  Facility

# FamilyHistory

Source: https://docs.canvasmedical.com/sdk/data-family-history/

##  Introduction 
The `FamilyHistory` model represents a patient's family medical history — the condition(s) recorded for one of the patient's relatives, captured by the `family_history` command. The relative is identified by a SNOMED code and term, and the condition(s) are stored as `FamilyHistoryCoding` records reachable through the `coding` accessor.
##  Basic usage 
To get a family history record by identifier, use the `get` method on the `FamilyHistory` model manager:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    family_history = FamilyHistory.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, a patient's family history can be accessed with the `family_histories` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    family_histories = patient.family_histories.all()
    ```
If you have a patient ID, you can get the family history for the patient with the `for_patient` method on the `FamilyHistory` model manager:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    family_histories = FamilyHistory.objects.for_patient(patient_id)
    ```
##  Codings 
The relative's condition coding records can be accessed with the `coding` attribute on a `FamilyHistory` object. `FamilyHistory` exposes this relation as the singular `coding`, unlike the plural `codings` on Condition, Procedure, and Immunization:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    from logger import log
    family_history = FamilyHistory.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in family_history.coding.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Family history records can be filtered by any attribute that exists on the model.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    family_histories = FamilyHistory.objects.filter(relation_snomed_term="Mother")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering, matching against the relative's condition coding records — the `coding` accessor — not the `relation_snomed_code`/`relation_snomed_term` fields:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    from canvas_sdk.value_set.v2022.condition import Diabetes
    family_histories = FamilyHistory.objects.find(Diabetes)
    ```
###  By coding 
To filter on coding records directly instead of a value set, filter across the relation to match the relative's condition coding records:
    ```python
    from canvas_sdk.v1.data.family_history import FamilyHistory
    family_histories = FamilyHistory.objects.filter(
        coding__code__in=["44054006", "46635009"],
    ).distinct()
    ```

# FollowUp

Source: https://docs.canvasmedical.com/sdk/data-follow-up/

##  Introduction 
The `FollowUp` model is the anchor for the [Follow Up](/sdk/commands/#followup) command — a requested follow-up (recall) recorded on a Note for a Patient.
##  Basic usage 
To get a follow up by identifier, use the `get` method on the `FollowUp` model manager:
    ```python
    from canvas_sdk.v1.data.follow_up import FollowUp
    follow_up = FollowUp.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient or note object, the follow ups can be accessed with the `follow_ups` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    follow_ups = patient.follow_ups.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    follow_ups = note.follow_ups.all()
    ```
##  Committed follow ups 
The `committed` method returns follow ups that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.follow_up import FollowUp
    committed_follow_ups = FollowUp.objects.committed()
    ```
##  Attributes

# Goal

Source: https://docs.canvasmedical.com/sdk/data-goal/

##  Introduction 
The `Goal` model represents a patient Goal in Canvas, which is always associated with a Note and a Patient.
This page also documents UpdateGoal, the record of a goal's updates and closures, created by committing an [UpdateGoal command](/sdk/commands/#updategoal) or [CloseGoal command](/sdk/commands/#closegoal).
##  Basic usage 
To get a goal by identifier, use the `get` method on the `Goal` model manager:
    ```python
    from canvas_sdk.v1.data.goal import Goal
    goal = Goal.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, or note object, the goals for a patient or note can be accessed with the `goals` attribute on a `Patient` or `Note` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    goals = patient.goals.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    goals = note.goals.all()
    ```
`UpdateGoal` records can be queried the same way, and each one links back to the goal it updates with the `goal` attribute:
    ```python
    from canvas_sdk.v1.data.goal import UpdateGoal
    update = UpdateGoal.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    goal = update.goal
    committed_updates = UpdateGoal.objects.committed()
    ```
##  Filtering 
Goals can be filtered by any attribute that exists on the model.
Filtering for goals is done with the `filter` method on the `Goal` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.goal import Goal, GoalAchievementStatus
    goals = Goal.objects.filter(achievement_status=GoalAchievementStatus.IN_PROGRESS)
    ```
###  Committed goals 
The `committed` method returns goals that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.goal import Goal
    committed_goals = Goal.objects.committed()
    ```
##  Goal updates and closures 
Each change to a goal — via the [UpdateGoal](/sdk/commands/#updategoal) or [CloseGoal](/sdk/commands/#closegoal) command — is recorded as an `UpdateGoal`. Update actions revise the goal while leaving it active; close actions also move it to a closed `lifecycle_status` (e.g. `completed`, `cancelled`, `rejected`). A goal's updates are reachable through its `updates` accessor:
    ```python
    from canvas_sdk.v1.data.goal import Goal
    goal = Goal.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    # Every update or close recorded against this goal.
    updates = goal.updates.all()
    # The most recent committed update — the goal's current state — or None.
    latest = goal.updates.committed().order_by("dbid").last()
    ```
`UpdateGoal` carries the same status, priority, and progress fields as `Goal` (without `goal_statement` / `start_date`), plus a `goal` foreign key back to the goal it updates. Like `Goal`, its manager supports `committed()` to filter to committed, non-entered-in-error records.

# HistoryOfPresentIllness

Source: https://docs.canvasmedical.com/sdk/data-history-present-illness/

##  Introduction 
The `HistoryOfPresentIllness` model represents a History of Present Illness (HPI) recorded on a Note, and is always associated with a Note and a Patient. It is the data model behind the `hpi` command.
##  Basic usage 
To get an HPI by identifier, use the `get` method on the `HistoryOfPresentIllness` model manager:
    ```python
    from canvas_sdk.v1.data.history_present_illness import HistoryOfPresentIllness
    hpi = HistoryOfPresentIllness.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, or note object, the histories of present illness for a patient or note can be accessed with the `histories_of_present_illness` attribute on a `Patient` or `Note` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    histories = patient.histories_of_present_illness.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    histories = note.histories_of_present_illness.all()
    ```
##  Reading the narrative 
The HPI text is stored as a structured document in `narrative_json`. The `narrative` property renders it as plain text, so that is the field to read:
    ```python
    from canvas_sdk.v1.data.history_present_illness import HistoryOfPresentIllness
    hpi = HistoryOfPresentIllness.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    text = hpi.narrative
    ```
##  Filtering 
Histories of present illness can be filtered by any column on the model. Note that `narrative` is a Python property rather than a column, so it cannot be used in `filter()` — filter on `narrative_json` instead.
###  Committed histories of present illness 
The `committed` method returns records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.history_present_illness import HistoryOfPresentIllness
    committed_histories = HistoryOfPresentIllness.objects.committed()
    ```
##  Attributes

# Imaging Report Template

Source: https://docs.canvasmedical.com/sdk/data-imaging-report-template/

##  Introduction 
The `ImagingReportTemplate`, `ImagingReportTemplateField`, and `ImagingReportTemplateFieldOption` models represent the templates used for imaging reports. Templates define the structure of an imaging report, including what fields need to be filled in and what options are available for each field.
##  Basic Usage 
To retrieve an `ImagingReportTemplate` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReportTemplate
    template = ImagingReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
To access the fields defined in a template:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReportTemplate
    template = ImagingReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    fields = template.fields.all()
    ```
##  Filtering 
Templates can be filtered by any attribute on the models.
###  By active status 
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReportTemplate
    active_templates = ImagingReportTemplate.objects.active()
    ```
###  By type 
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReportTemplate
    # Get custom (user-created) templates
    custom = ImagingReportTemplate.objects.custom()
    # Get built-in (system) templates
    builtin = ImagingReportTemplate.objects.builtin()
    ```
###  By search 
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReportTemplate
    results = ImagingReportTemplate.objects.search("chest x-ray")
    ```

# Imaging

Source: https://docs.canvasmedical.com/sdk/data-imaging/

##  Introduction 
The `ImagingOrder`, `ImagingReview`, `ImagingReport`, and `ImagingReportCoding` models represent imaging results.
##  Basic Usage 
To retrieve an `ImagingOrder`, `ImagingReview`, or `ImagingReport` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder, ImagingReview, ImagingReport
    imaging_order = ImagingOrder.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    imaging_review = ImagingReview.objects.get(id="c02c6b02-2581-46bf-819c-b5aacad2134c")
    imaging_report = ImagingReport.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    ```
If you have a patient object, the orders, reviews, and reports can be accessed with the `imaging_orders`, `imaging_reviews`, and `imaging_results` attributes, respectively on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    orders = patient.imaging_orders.all()
    reviews = patient.imaging_reviews.all()
    reports = patient.imaging_results.all()
    ```
##  Filtering 
Imaging orders, reviews, and reports can be filtered by any attribute that exists on the models.
Filtering is done with the `filter` method on the `ImagingOrder`, `ImagingReview`, and `ImagingReport` model managers.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder, ImagingReview, ImagingReport
    orders = ImagingOrder.objects.filter(status="completed")
    reviews = ImagingReview.objects.filter(is_released_to_patient=False)
    reports = ImagingReport.objects.filter(requires_signature=True)
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
`ImagingReport` supports `ValueSet` filtering through the `find` method on its model manager:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReport
    from canvas_sdk.value_set.v2022.diagnostic_study import Mammography
    reports = ImagingReport.objects.find(Mammography)
    ```
`find` joins through the report's `codings` reverse relation and matches on `(system, code)` pairs from the value set, so a coding must match both the code system and the code to be included.
###  Committed records 
The `committed` method returns `ImagingOrder` and `ImagingReview` records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder, ImagingReview
    committed_orders = ImagingOrder.objects.committed()
    committed_reviews = ImagingReview.objects.committed()
    ```
##  Related Tasks 
To retrieve an Imaging Order's related tasks, use the `get_task_objects` method on the ImagingOrder object.
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder
    imaging_order = ImagingOrder.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    tasks = imaging_order.get_task_objects().all()
    ```
The `task_list` computed property returns the same related tasks as a `list[Task]`:
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder
    imaging_order = ImagingOrder.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    tasks = imaging_order.task_list
    ```
##  Accessing the report file 
The `document_url` property on `ImagingReport` returns a presigned S3 URL for securely accessing the report's file. The URL is valid for one hour and is regenerated on each access, so don't persist or cache it. If the report has no associated file, `document_url` returns `None`.
    ```python
    from canvas_sdk.v1.data.imaging import ImagingReport
    imaging_report = ImagingReport.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    # Presigned S3 URL to the report file, or None if the report has no file
    url = imaging_report.document_url
    ```
##  The document reference 
A report that has a file also has a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at it — the record that carries the report's document coding, category, and status, and that represents it in the FHIR API. `document_url` above is the direct route to the file itself; reach for the document reference when you want that surrounding metadata.
Resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the report's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, ImagingReport
    imaging_report = ImagingReport.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    content_type = ContentType.objects.filter(app_label="api", model="imagingreport").first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=imaging_report.dbid
    ).first()
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`. A report with no file has no document reference, so handle `None`.

# Immunization

Source: https://docs.canvasmedical.com/sdk/data-immunization/

##  Introduction 
The `Immunization` model represents a record of immunization events and immunization statements for a patient. Immunizations can be actively administered medications or historical records of immunizations received elsewhere. The `ImmunizationStatement` model represents historical immunization records and vaccination history.
##  Basic usage 
To get an immunization by identifier, use the `get` method on the `Immunization` model manager:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    immunization = Immunization.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the immunizations for a patient can be accessed with the `immunizations` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    immunizations = patient.immunizations.all()
    ```
If you have a patient ID, you can get the immunizations for the patient with the `for_patient` method on the `Immunization` model manager:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    immunizations = Immunization.objects.for_patient(patient_id)
    ```
##  Codings 
The codings for an immunization can be accessed with the `codings` attribute on an `Immunization` object:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    from logger import log
    immunization = Immunization.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in immunization.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Immunizations can be filtered by any attribute that exists on the model.
Filtering for immunizations is done with the `filter` method on the `Immunization` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    immunizations = Immunization.objects.filter(status="completed")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    from canvas_sdk.value_set.v2022.immunization import InfluenzaVaccine
    immunizations = Immunization.objects.find(InfluenzaVaccine)
    ```
`find` also works on the `ImmunizationStatement` model manager, matching against the statement's own coding records, which it exposes through the singular `coding` accessor (unlike `Immunization.codings`):
    ```python
    from canvas_sdk.v1.data.immunization import ImmunizationStatement
    from canvas_sdk.value_set.v2022.immunization import InfluenzaVaccine
    immunization_statements = ImmunizationStatement.objects.find(InfluenzaVaccine)
    ```
###  Committed and active records 
The `committed` method returns immunizations that have been committed and not entered in error. The `active` method is an alias for `committed` and returns the same records:
    ```python
    from canvas_sdk.v1.data.immunization import Immunization
    committed_immunizations = Immunization.objects.committed()
    active_immunizations = Immunization.objects.active()
    ```
The same methods are available on the `ImmunizationStatement` model manager:
    ```python
    from canvas_sdk.v1.data.immunization import ImmunizationStatement
    committed_statements = ImmunizationStatement.objects.committed()
    active_statements = ImmunizationStatement.objects.active()
    ```
##  Immunization Statements 
To work with immunization statements (historical records), use the `ImmunizationStatement` model:
    ```python
    from canvas_sdk.v1.data.immunization import ImmunizationStatement
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    immunization_statements = ImmunizationStatement.objects.for_patient(patient_id)
    ```

# Instruction

Source: https://docs.canvasmedical.com/sdk/data-instruction/

##  Introduction 
The `Instruction` model represents an `Instruct` command in a patient's note — for example, "cessation of smoking" counseling, dietary instructions, or any other piece of clinical guidance recorded as an Instruct command. Instructions are included regardless of command state (staged or committed); use `.committed()` to filter to only committed commands.
Querying `Instruction` from a plugin is the recommended way to ask "has this patient been given an instruction in this value set?" — for example, when computing quality measures that look for tobacco cessation counseling or dialysis education.
##  Basic usage 
To get an instruction by identifier, use the `get` method on the `Instruction` model manager:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    instruction = Instruction.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the instructions for a patient can be accessed with the `instructions` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    # Returns all instructions for the patient, regardless of command state (staged or committed)
    instructions = patient.instructions.all()
    ```
If you have a patient ID, you can get the instructions for the patient with the `for_patient` method on the `Instruction` model manager:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    # All instructions for the patient, regardless of command state (staged or committed)
    instructions = Instruction.objects.for_patient(patient_id)
    # Only committed instructions for the patient
    committed_instructions = Instruction.objects.for_patient(patient_id).committed()
    ```
##  Codings 
The codings for an instruction can be accessed with the `codings` attribute on an `Instruction` object:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    from logger import log
    instruction = Instruction.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in instruction.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
Instruct commands originated through the SDK use either the SNOMED CT code system or an internal "unstructured" system for free-text instructions. See the [InstructCommand](/sdk/commands/#instruct) effect for the write-side details.
##  Committed instructions 
The `committed` method returns instructions whose underlying command has been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    committed_instructions = Instruction.objects.committed()
    ```
##  Filtering 
Instructions can be filtered by any attribute that exists on the model.
Filtering for instructions is done with the `filter` method on the `Instruction` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    instructions = Instruction.objects.filter(note__id="2c91b0d8-7b9d-4ef1-89e2-1f9a3a8a2b14")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.instruction import Instruction
    from canvas_sdk.value_set.v2022.intervention import TobaccoUseCessationCounseling
    cessation_counseling = (
        Instruction.objects
        .for_patient("1eed3ea2a8d546a1b681a2a45de1d790")
        .committed()
        .find(TobaccoUseCessationCounseling)
    )
    ```
`find` joins through the `codings` reverse relation and filters on `(system, code)` pairs from the value set, so it composes naturally with `for_patient` and `committed`.

# Integration Task

Source: https://docs.canvasmedical.com/sdk/data-integration-task/

##  Introduction 
The `IntegrationTask` and `IntegrationTaskReview` models represent incoming documents that need processing in Canvas. Integration tasks are created when documents arrive via fax, document upload, integration engine, or the patient portal. Each task can have one or more reviews that track who is responsible for processing the document and its current state.
##  Basic Usage 
To retrieve an `IntegrationTask` or `IntegrationTaskReview` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.integration_task import IntegrationTask, IntegrationTaskReview
    task = IntegrationTask.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    review = IntegrationTaskReview.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    ```
If you have a patient object, integration tasks can be accessed with the `integration_tasks` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    tasks = patient.integration_tasks.all()
    ```
##  Filtering 
Integration tasks and reviews can be filtered by any attribute that exists on the models.
###  By status 
Filter tasks by their processing status:
    ```python
    from canvas_sdk.v1.data.integration_task import IntegrationTask
    # Get all unread tasks
    unread = IntegrationTask.objects.unread()
    # Get tasks pending review (UNREAD or READ)
    pending = IntegrationTask.objects.pending_review()
    # Get processed tasks (PROCESSED or REVIEWED)
    processed = IntegrationTask.objects.processed()
    # Get tasks with errors
    errored = IntegrationTask.objects.with_errors()
    # Get non-junked tasks
    active = IntegrationTask.objects.not_junked()
    ```
###  By channel 
Filter tasks by their source channel:
    ```python
    from canvas_sdk.v1.data.integration_task import IntegrationTask
    faxes = IntegrationTask.objects.faxes()
    uploads = IntegrationTask.objects.uploads()
    engine_tasks = IntegrationTask.objects.from_integration_engine()
    portal_tasks = IntegrationTask.objects.from_patient_portal()
    ```
###  By patient 
    ```python
    from canvas_sdk.v1.data.integration_task import IntegrationTask
    tasks = IntegrationTask.objects.for_patient("patient-id")
    ```
###  Filtering reviews 
    ```python
    from canvas_sdk.v1.data.integration_task import IntegrationTaskReview
    # Get reviews for a specific task
    reviews = IntegrationTaskReview.objects.for_task("task-id")
    # Get active (non-junked) reviews
    active_reviews = IntegrationTaskReview.objects.active()
    # Get reviews by a specific reviewer
    reviewer_reviews = IntegrationTaskReview.objects.by_reviewer("staff-id")
    # Get reviews assigned to a specific team
    team_reviews = IntegrationTaskReview.objects.by_team("team-id")
    ```

# Invoice

Source: https://docs.canvasmedical.com/sdk/data-invoice/

##  Introduction 
The `Invoice` model represents a statement generated for a patient or their guarantor — who it was addressed to, what it totals, how it was sent, and where it stands.
Invoices are produced by Canvas billing workflows rather than by plugins: automated statement runs, batch runs, and one-off statements each record their origin in `workflow`.
> **Info:** Invoice records have no UUID `id` — they are identified by their integer `dbid`.
##  Basic Usage 
    ```python
    from canvas_sdk.v1.data import Invoice
    invoice = Invoice.objects.get(dbid=42)
    ```
If you have a `Patient` object, the statements addressed to them are available through the `invoices` reverse relation:
    ```python
    from canvas_sdk.v1.data import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    invoices = patient.invoices.all()
    ```
A [Claim](/sdk/data-claim/#claim) points at the most recent statement it appeared on:
    ```python
    from canvas_sdk.v1.data import Claim
    claim = Claim.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    invoice = claim.latest_invoice
    ```
##  Filtering 
    ```python
    from canvas_sdk.v1.data.invoice import Invoice, InvoiceStatus, InvoiceWorkflow
    # Active statements only
    active = Invoice.objects.filter(status=InvoiceStatus.ACTIVE)
    # Statements a staff member generated one at a time, rather than by a batch or automated run
    adhoc = Invoice.objects.filter(workflow=InvoiceWorkflow.ADHOC)
    ```
`Invoice` is addressed through `recipient` rather than a `patient` field, so filter on `recipient` to scope to one patient:
    ```python
    from canvas_sdk.v1.data import Invoice
    invoices = Invoice.objects.filter(recipient__id="1eed3ea2a8d546a1b681a2a45de1d790")
    ```
##  Accessing the statement PDF 
`Invoice` holds the statement's amounts and delivery details, not the rendered file. Canvas attaches the PDF to a [DocumentReference](/sdk/data-document-reference/#the-related-object), which you reach by resolving the [ContentType](/sdk/data-content-type/) for the invoice and matching `object_id` against the invoice's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, Invoice
    invoice = Invoice.objects.get(dbid=42)
    content_type = ContentType.objects.filter(
        app_label="quality_and_revenue", model="invoicefull"
    ).first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=invoice.dbid
    ).first()
    url = document.document_url if document else None
    ```
##  Attributes

# LabPartner, LabPartnerTest & AOE Questions

Source: https://docs.canvasmedical.com/sdk/data-lab-partner-and-test/

##  Introduction 
The **LabPartner** , **LabPartnerTest** , **LabPartnerTestQuestion** , and **LabPartnerTestQuestionChoice** models represent external lab partners, the tests they offer, and the ask-at-order-entry (AOE) questions associated with each test within Canvas.
* * *
##  LabPartner 
The `LabPartner` model stores information about a lab partner
###  Basic Usage 
To retrieve a lab partner by its unique identifier:
    ```python
    from canvas_sdk.v1.data.lab import LabPartner
    lab_partner = LabPartner.objects.get(id="your-uuid-here")
    ```
You can also filter lab partners by attributes. For example, to list all active lab partners:
    ```python
    from canvas_sdk.v1.data.lab import LabPartner
    active_lab_partners = LabPartner.objects.filter(active=True)
    ```
##  LabPartnerTest 
The `LabPartnerTest` model represents a test offered by a lab partner. Each test is linked to a lab partner via a foreign key.
###  Basic Usage 
To retrieve tests for a given lab partner, you can access the related tests using the reverse relationship:
    ```python
    from canvas_sdk.v1.data.lab import LabPartner
    lab_partner = LabPartner.objects.get(id="your-uuid-here")
    tests = lab_partner.available_tests.all()
    ```
Alternatively, you can directly filter tests by attributes:
    ```python
    from canvas_sdk.v1.data.lab import LabPartnerTest
    tests_with_code = LabPartnerTest.objects.filter(order_code="XYZ123")
    ```
##  Attributes 
###  LabPartner

cpt_code| String| The CPT code for the test, if available. Can be blank or null.  
questions| LabPartnerTestQuestion[]| AOE questions associated with this test.  
* * *
##  LabPartnerTestQuestion 
The `LabPartnerTestQuestion` model represents an ask-at-order-entry (AOE) question associated with a lab partner test. AOE questions are prompts that must be answered when ordering a specific lab test (e.g., "Is the patient fasting?", "Source of specimen").
###  Basic Usage 
To retrieve questions for a given lab partner test:
    ```python
    from canvas_sdk.v1.data.lab import LabPartnerTest
    test = LabPartnerTest.objects.get(id="your-uuid-here")
    questions = test.questions.all()
    ```
To filter for required questions only:
    ```python
    required_questions = test.questions.filter(required=True)
    ```
To directly query questions by code:
    ```python
    from canvas_sdk.v1.data.lab import LabPartnerTestQuestion
    questions = LabPartnerTestQuestion.objects.filter(code="FAST")
    ```
* * *
##  LabPartnerTestQuestionChoice 
The `LabPartnerTestQuestionChoice` model represents a selectable answer option for an AOE question. Not all questions have predefined choices (e.g., free-text questions may have none).
###  Basic Usage 
To retrieve choices for a given question:
    ```python
    question = test.questions.first()
    choices = question.choices.all()
    ```
###  Example: Building AOE prompts for a lab test 
    ```python
    from canvas_sdk.v1.data.lab import LabPartnerTest
    from logger import log
    test = LabPartnerTest.objects.get(id="your-uuid-here")
    for question in test.questions.all():
        log.info(f"Question: {question.body} (required={question.required})")
        for choice in question.choices.all():
            log.info(f"  - {choice.label}: {choice.value}")
    ```

# Lab Report Template

Source: https://docs.canvasmedical.com/sdk/data-lab-report-template/

##  Introduction 
The `LabReportTemplate`, `LabReportTemplateField`, and `LabReportTemplateFieldOption` models represent the templates used for point-of-care (POC) labs and custom lab reports. Templates define the structure of a lab report, including what fields need to be filled in and what options are available for each field.
##  Basic Usage 
To retrieve a `LabReportTemplate` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.lab import LabReportTemplate
    template = LabReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
To access the fields defined in a template:
    ```python
    from canvas_sdk.v1.data.lab import LabReportTemplate
    template = LabReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    fields = template.fields.all()
    ```
##  Filtering 
Templates can be filtered by any attribute on the models.
###  By active status 
    ```python
    from canvas_sdk.v1.data.lab import LabReportTemplate
    # Get all active templates
    active_templates = LabReportTemplate.objects.active()
    # Get inactive templates
    inactive_templates = LabReportTemplate.objects.inactive()
    ```
###  By type 
    ```python
    from canvas_sdk.v1.data.lab import LabReportTemplate
    # Get custom (user-created) templates
    custom = LabReportTemplate.objects.custom()
    # Get built-in (system) templates
    builtin = LabReportTemplate.objects.builtin()
    # Get point-of-care test templates
    poc = LabReportTemplate.objects.point_of_care()
    ```
###  By search

# Labs

Source: https://docs.canvasmedical.com/sdk/data-labs/

##  Introduction 
The Canvas SDK provides comprehensive models for working with laboratory data throughout the entire lab workflow—from ordering tests to reviewing results. The primary models include:
  - **`LabOrder`** : Represents a lab order placed for a patient, including order details, transmission type, and associated tests
  - **`LabTest`** : Individual tests within a lab order, tracking status from creation through processing
  - **`LabReport`** : Contains the results returned from the lab, including all values and associated metadata
  - **`LabReportRemark`** : Report-level remarks from lab personnel, accessible via `LabReport.remarks`
  - **`LabValue`** : Individual test results within a lab report, including values, units, and reference ranges
  - **`LabReview`** : Tracks the clinical review process for lab results, including provider comments and patient communication
  - **`DiagnosticReport`** : The `DiagnosticReport` linked to a `LabReport`, accessible via `LabReport.diagnostic_reports`
##  Basic Usage 
To retrieve a `LabReport` model by id, use the `objects.get` method on the model. For example:
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    ```
##  Filtering 
To retrieve the `LabValue` instances that are associated with the `LabReport`, you can either call the `values` on the `LabReport` instance:
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    lab_values = lab_report.values.all()
    ```
Or query the `LabValue` model and pass the `report` argument:
    ```python
    from canvas_sdk.v1.data.lab import LabReport, LabValue
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    lab_values = LabValue.objects.filter(lab_report=lab_report)
    ```
Additionally, codings for lab values can be attained by querying the `LabValueCoding` model. To retrieve the codings associated with a `LabValue`, you can call `codings` on the `LabValue` instance:
    ```python
    from logger import log
    from canvas_sdk.v1.data.lab import LabReport, LabValue
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    lab_values = LabValue.objects.filter(lab_report=lab_report)
    for value in lab_values:
        log.info(value.codings.all())
    ```
Or query the `LabValueCoding` model directly:
    ```python
    from logger import log
    from canvas_sdk.v1.data.lab import LabReport, LabValue, LabValueCoding
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    lab_values = LabValue.objects.filter(lab_report=lab_report)
    for value in lab_values:
        lab_value_codings = LabValueCoding.objects.filter(value=value)
        log.info(lab_value_codings)
    ```
###  Ordered vs. result tests 
A `LabReport` references two kinds of `LabTest` rows, and `LabReport` exposes each as its own property:
  - **`ordered_tests`** : `LabTest` rows created when a `LabOrder` is placed. These represent the tests that were requested and are not associated with any `LabValue` records.
  - **`result_tests`** : `LabTest` rows created for the results themselves. For FHIR `DiagnosticReport` and Health Gorilla ingested reports, `LabValue` records are attached to these tests.
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    lab_report = LabReport.objects.get(id="bcd287b7-8b04-4540-a1ea-6529eb576565")
    for test in lab_report.ordered_tests:
        print(f"Ordered: {test.ontology_test_name}")
    for test in lab_report.result_tests:
        print(f"Result: {test.ontology_test_name}")
        for value in test.values.all():
            print(f"  {value.value} {value.units}")
    ```
When iterating many reports at once, the `LabReport` queryset exposes `with_result_tests_and_values()` to prefetch each report's result tests (with their values) and the report's full value list in bulk:
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    reports = (
        LabReport.objects
        .filter(patient__id="patient-id")
        .with_result_tests_and_values()
    )
    ```
To query all lab reports for a particular patient, the `patient` argument can be used:
    ```python
    from logger import log
    from canvas_sdk.v1.data.lab import LabReport
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="6cbc40b408294a5f9b41f57ba1b2b487")
    lab_report = LabReport.objects.filter(patient=patient)
    ```
##  Example 
The following plugin code will run every time a new Lab Report is created and log the patient it is for, along with the values and codings from the report's results:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    from canvas_sdk.v1.data.lab import LabReport
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.LAB_REPORT_CREATED)
        def compute(self):
            lab_report = LabReport.objects.select_related("patient").get(id=self.target)
            if lab_report.patient:
                log.info(f"{lab_report.patient.first_name} {lab_report.patient.last_name}")
            for value in lab_report.values.all():
                log.info(f"{value.value} {value.units}")
                for coding in value.codings.all():
                    log.info(coding.system)
                    log.info(coding.name)
                    log.info(coding.code)
            return []
    ```
For complete field documentation on all lab models, see the Attributes section below.
###  Working with Lab Orders and Tests 
You can also work with lab orders and their associated tests. Here's an example of querying a lab order and checking the status of its tests:
    ```python
    from canvas_sdk.v1.data.lab import LabOrder, LabTest
    # Get a lab order by ID
    lab_order = LabOrder.objects.get(id="abc123...")
    # Access all tests in the order
    for test in lab_order.tests.all():
        print(f"Test: {test.ontology_test_name}")
        print(f"Status: {test.status}")
        print(f"Code: {test.ontology_test_code}")
        # Check if results have been received
        if test.report:
            print(f"Report available with {test.report.values.count()} values")
    ```
###  Navigating Between Lab Orders and Reports 
Lab orders and lab reports are connected through the `LabTest` model. Here's how to navigate between them:
####  Getting the LabOrder from a LabReport 
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    # Get a lab report
    lab_report = LabReport.objects.get(id="report-id")
    # Direct access to all orders via the reverse many-to-many relationship
    for lab_order in lab_report.laborder_set.all():
        print(f"Order ID: {lab_order.id}")
        print(f"Ordered by: {lab_order.ordering_provider.full_name if lab_order.ordering_provider else 'N/A'}")
        print(f"Date ordered: {lab_order.date_ordered}")
    # Alternatively, access the order through the tests
    for test in lab_report.tests.all():
        lab_order = test.order
        print(f"Order ID: {lab_order.id}")
        break  # Usually all tests in a report share the same order
    ```
####  Getting LabReports from a LabOrder 
    ```python
    from canvas_sdk.v1.data.lab import LabOrder
    # Get a lab order
    lab_order = LabOrder.objects.get(id="order-id")
    # Direct access to all reports via the many-to-many relationship
    for report in lab_order.reports.all():
        print(f"Report ID: {report.id}")
        print(f"Date performed: {report.date_performed}")
        print(f"Number of values: {report.values.count()}")
    # Alternatively, access reports through the tests if you need test-level details
    for test in lab_order.tests.all():
        if test.report:
            print(f"Test: {test.ontology_test_name}")
            print(f"Report ID: {test.report.id}")
    ```
###  Working with Diagnostic Reports 
A `LabReport` may be linked to one or more `DiagnosticReport` records. The `DiagnosticReport` model exposes its `id`, `status`, the `subject` (Patient), and the `lab` foreign key back to the originating `LabReport`.
####  Getting the DiagnosticReport(s) from a LabReport 
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    lab_report = LabReport.objects.get(id="report-id")
    for diagnostic_report in lab_report.diagnostic_reports.all():
        print(f"DiagnosticReport ID: {diagnostic_report.id}")
        print(f"Status: {diagnostic_report.status}")
    ```
####  Following a DiagnosticReport back to its LabReport 
    ```python
    from canvas_sdk.v1.data.diagnostic_report import DiagnosticReport
    diagnostic_report = DiagnosticReport.objects.get(id="diagnostic-report-id")
    # Follow the `lab` foreign key back to the originating LabReport
    lab_report = diagnostic_report.lab
    if lab_report:
        print(f"LabReport ID: {lab_report.id}")
    ```
####  Filtering DiagnosticReports by patient 
    ```python
    from canvas_sdk.v1.data.diagnostic_report import DiagnosticReport
    diagnostic_reports = DiagnosticReport.objects.for_patient("patient-id")
    ```
####  Reconciling with FHIR 
A `DiagnosticReport`'s `id` is the same id used by the FHIR API, so you can start from a `LabReport`, grab its `DiagnosticReport`, and use the FHIR client to read the corresponding FHIR [DiagnosticReport](/api/diagnosticreport/) resource:
    ```python
    from canvas_sdk.clients.canvas_fhir import CanvasFhir
    from canvas_sdk.v1.data.lab import LabReport
    lab_report = LabReport.objects.get(id="report-id")
    diagnostic_report = lab_report.diagnostic_reports.first()
    # Declare these secrets in the CANVAS_MANIFEST.json and set the values on the
    # plugin configuration page.
    client = CanvasFhir(
        self.secrets["CANVAS_FHIR_CLIENT_ID"],
        self.secrets["CANVAS_FHIR_CLIENT_SECRET"],
    )
    # Use the DiagnosticReport's id to read the corresponding FHIR DiagnosticReport resource.
    fhir_diagnostic_report = client.read("DiagnosticReport", str(diagnostic_report.id))
    ```
###  Working with Lab Reviews 
Lab reviews track the clinical review process for lab results, including provider comments and patient communication. Here's how to work with the LabReport and LabReview relationship:
####  Accessing the Review from a LabReport 
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    # Get a lab report
    lab_report = LabReport.objects.get(id="report-id")
    # Check if the report has been reviewed
    if lab_report.review:
        lab_review = lab_report.review
        print(f"Review status: {lab_review.status}")
        print(f"Internal comment: {lab_review.internal_comment}")
        print(f"Message to patient: {lab_review.message_to_patient}")
        # Access the provider who reviewed it
        if lab_review.originator:
            print(f"Reviewed by: {lab_review.originator.full_name}")
    else:
        print("Report has not been reviewed yet")
    ```
####  Accessing Reports from a LabReview 
    ```python
    from canvas_sdk.v1.data.lab import LabReview
    # Get a lab review
    lab_review = LabReview.objects.get(id="review-id")
    # Access all reports in this review batch
    for report in lab_review.reports.all():
        print(f"Report ID: {report.id}")
        print(f"Date performed: {report.date_performed}")
        print(f"Number of values: {report.values.count()}")
        # Check if this report requires signature
        if report.requires_signature:
            print("  ⚠️  Requires provider signature")
    ```
####  Finding Unreviewed Lab Reports 
    ```python
    from canvas_sdk.v1.data.lab import LabReport
    from canvas_sdk.v1.data.patient import Patient
    # Get all unreviewed lab reports for a patient
    patient = Patient.objects.get(id="patient-id")
    unreviewed_reports = LabReport.objects.filter(
        patient=patient,
        review__isnull=True,
        deleted=False
    )
    print(f"Found {unreviewed_reports.count()} unreviewed reports")
    for report in unreviewed_reports:
        print(f"Report from {report.date_performed} - {report.values.count()} values")
    ```
###  Filtering Lab Results by Abnormal Values 
A common use case is to identify abnormal lab values that may require clinical attention:
    ```python
    from canvas_sdk.v1.data.lab import LabReport, LabValue
    from canvas_sdk.v1.data.patient import Patient
    # Get all lab reports for a patient
    patient = Patient.objects.get(id="patient-id")
    lab_reports = LabReport.objects.filter(patient=patient)
    # Find all abnormal values
    for report in lab_reports:
        abnormal_values = report.values.filter(abnormal_flag__isnull=False).exclude(abnormal_flag="")
        if abnormal_values.exists():
            print(f"Report from {report.date_performed}:")
            for value in abnormal_values:
                for coding in value.codings.all():
                    print(f"  {coding.name}: {value.value} {value.units} (Flag: {value.abnormal_flag})")
    ```
###  Committed records 
The `committed` method returns `LabReport`, `LabReview`, `LabOrder`, and `LabOrderReason` records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.lab import LabReport, LabReview, LabOrder, LabOrderReason
    committed_reports = LabReport.objects.committed()
    committed_reviews = LabReview.objects.committed()
    committed_orders = LabOrder.objects.committed()
    committed_order_reasons = LabOrderReason.objects.committed()
    ```
##  The document reference 
`LabReport` carries the report's values and review state, not a file. When the report is reviewed, Canvas renders it to a PDF and stores it on a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at the report.
To find it, resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the report's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, LabReport
    report = LabReport.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    content_type = ContentType.objects.filter(app_label="api", model="labreport").first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=report.dbid
    ).first()
    url = document.document_url if document else None
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`. A report that has not been reviewed yet has no document reference, so handle `None`.

# LetterActionEvent

Source: https://docs.canvasmedical.com/sdk/data-letter-action-event/

##  Introduction 
The `LetterActionEvent` model represents occurrences of a letter being printed or faxed within Canvas. LetterActionEvents are associated with a [Letter](/sdk/data-letter/).
##  Basic Usage 
###  Retrieve a specific letter action event 
To get a letter action event by identifier, use the `get` method on the `LetterActionEvent` model manager:
    ```python
    from canvas_sdk.v1.data.letter import LetterActionEvent
    letterActionEvent = LetterActionEvent.objects.get(id="b5a0c1d2-e3f4-5678-9abc-def012345678")
    ```
###  Find a letter action event for a specific letter 
If you have a letter object, you can access its associated letter_action_events using the `letter_action_events` attribute:
    ```python
    from canvas_sdk.v1.data.letter import Letter
    letter = Letter.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    letter_action_events = letter.letter_action_events
    ```
##  Filtering 
LetterActionEvents can be filtered by any attribute that exists on the model.
###  By attribute 
Filtering for letter action events is done with the `filter` method on the `LetterActionEvent` model manager:
    ```python
    from canvas_sdk.v1.data.letter import LetterActionEvent
    # Find all successful deliveries
    delivered_letters = LetterActionEvent.objects.filter(delivered_by_fax=True)
    # Find letter action events with a specific send_fax_id
    letter_action_events = LetterActionEvent.objects.filter(send_fax_id="a1b2c3d4e5f6")
    ```
##  Attributes 
###  LetterActionEvent 
Field Name| Type| Notes  
---|---|---  
id| UUID|   
dbid| Integer|   
created| DateTime|   
modified| DateTime|   
event_type| EventType| The type of the event  
send_fax_id| String| The id of the sent fax  
received_by_fax| Boolean| The isSuccess status of the received by fax  
delivered_by_fax| Boolean| The isSuccess status of the delivered by fax  
fax_result_msg| str| The fax result message  
letter| [Letter](/sdk/data-letter/)| The letter this action event is associated with  
originator| [User](/sdk/data-canvasuser/)| The user who created the letter (nullable)  
##  Enumeration types 
###  Event Type 
Value| Label  
---|---  
PRINTED| Printed  
FAXED| Faxed

# Letter

Source: https://docs.canvasmedical.com/sdk/data-letter/

##  Introduction 
The `Letter` model represents patient correspondence letters created within Canvas. Letters are associated with a [Note](/sdk/data-note/) and contain rendered content that can be printed or sent to patients.
##  Basic Usage 
###  Retrieve a specific letter 
To get a letter by identifier, use the `get` method on the `Letter` model manager:
    ```python
    from canvas_sdk.v1.data.letter import Letter
    letter = Letter.objects.get(id="b5a0c1d2-e3f4-5678-9abc-def012345678")
    ```
###  Find a letter for a specific note 
If you have a note object, you can access its associated letter using the `letter` attribute:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    letter = note.letter
    ```
###  Find all letters created by a staff member 
If you have a staff object, you can find all letters they created using the `letters` attribute:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="a1b2c3d4e5f6")
    staff_letters = staff.letters.all()
    ```
##  Filtering 
Letters can be filtered by any attribute that exists on the model.
###  By attribute 
Filtering for letters is done with the `filter` method on the `Letter` model manager:
    ```python
    from canvas_sdk.v1.data.letter import Letter
    # Find all printed letters
    printed_letters = Letter.objects.filter(printed__isnull=False)
    # Find letters created by a specific staff member
    staff_letters = Letter.objects.filter(staff_id="a1b2c3d4e5f6")
    ```
##  The document reference 
`content` holds the letter's body, not the document that goes out. Canvas renders the letter — including anything attached to it — to a PDF and stores it on a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at the letter.
To read that PDF, resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the letter's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, Letter
    letter = Letter.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    content_type = ContentType.objects.filter(app_label="api", model="letter").first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=letter.dbid
    ).first()
    url = document.document_url if document else None
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`. The PDF is rendered after the letter is created rather than with it, so handle `None`.

# Medication History

Source: https://docs.canvasmedical.com/sdk/data-medication-history/

##  Introduction 
The `MedicationHistoryMedication` model represents historical medication data for a patient, typically imported from external sources such as health information exchanges or pharmacy systems. The `MedicationHistoryResponse` model tracks responses to medication history requests.
##  Basic usage 
To get a medication history record by identifier, use the `get` method on the `MedicationHistoryMedication` model manager:
    ```python
    from canvas_sdk.v1.data.medication_history import MedicationHistoryMedication
    medication_history = MedicationHistoryMedication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the medication history for a patient can be accessed with the `medication_history_medications` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    medication_history = patient.medication_history_medications.all()
    ```
##  Codings 
The codings for a medication history record can be accessed with the `codings` attribute on a `MedicationHistoryMedication` object:
    ```python
    from canvas_sdk.v1.data.medication_history import MedicationHistoryMedication
    from logger import log
    medication_history = MedicationHistoryMedication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in medication_history.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Medication history records can be filtered by any attribute that exists on the model.
Filtering is done with the `filter` method on the `MedicationHistoryMedication` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.medication_history import MedicationHistoryMedication
    medications = MedicationHistoryMedication.objects.filter(dea_schedule="CII")
    ```
###  By date range 
Filter by last fill date or written date:
    ```python
    from canvas_sdk.v1.data.medication_history import MedicationHistoryMedication
    from datetime import datetime
    medications = MedicationHistoryMedication.objects.filter(
        last_fill_date__gte=datetime(2023, 1, 1)
    )

# Medication Statement

Source: https://docs.canvasmedical.com/sdk/data-medication-statement/

##  Introduction 
The `MedicationStatement` model represents a record of a medication statement by a patient from the past.
##  Basic usage 
To get a medication statement by identifier, use the `get` method on the `MedicationStatement` model manager:
    ```python
    from canvas_sdk.v1.data import MedicationStatement
    medication_statement = MedicationStatement.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    ```
If you have a patient object, the medication statements for a patient can be accessed with the `medication_statements` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    medication_statements = patient.medication_statements.all()
    ```
You can also access the referenced medication with the `medication` attribute:
    ```python
    from canvas_sdk.v1.data import MedicationStatement
    medication_statement = MedicationStatement.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    medication = medication_statement.medication
    ```
Or for a given medication, you can access all medication statements:
    ```python
    from canvas_sdk.v1.data import Medication
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    medication_statements = medication.medication_statements.all()
    ```
##  Committed records 
The `committed` method returns medication statements that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import MedicationStatement
    committed_medication_statements = MedicationStatement.objects.committed()
    ```
##  Attributes

# Medication

Source: https://docs.canvasmedical.com/sdk/data-medication/

##  Introduction 
The `Medication` model represents a record of a medication that is being consumed by a patient, either now, in the past, or in the future. `Medication` records can represent both prescriptions and medication statements for a patient.
##  Basic usage 
To get a medication by identifier, use the `get` method on the `Medication` model manager:
    ```python
    from canvas_sdk.v1.data.medication import Medication
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the medications for a patient can be accessed with the `medications` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    medications = patient.medications.all()
    ```
If you have a patient ID, you can get the medications for the patient with the `for_patient` method on the `Medication` model manager:
    ```python
    from canvas_sdk.v1.data.medication import Medication
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    medication = Medication.objects.for_patient(patient_id)
    ```
#  Codings 
The codings for a medication can be accessed with the `codings` attribute on an `Medication` object:
    ```python
    from canvas_sdk.v1.data.medication import Medication
    from logger import log
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in medication.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Medications can be filtered by any attribute that exists on the model.
Filtering for medications is done with the `filter` method on the `Medication` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.medication import Medication
    medications = Medication.objects.filter(status="active")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.medication import Medication
    from canvas_sdk.value_set.v2022.medication import AdhdMedications
    medications = Medication.objects.find(AdhdMedications)
    ```

# Note

Source: https://docs.canvasmedical.com/sdk/data-note/

##  Introduction 
The `Note` model represents clinical notes that appear on a patient's chart. A `Note` can contain multiple [commands](/sdk/data-command).
##  Basic usage 
###  Retrieve a specific note 
To get a note by identifier, use the `get` method on the `Note` model manager:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    ```
###  Find all notes for a patient 
If you have a patient object, the notes for a patient can be found using the `notes` attribute on the `Patient` instance:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="fd2ecd87c26044a6a755287f296dd17f")
    patient_notes = patient.notes.all()
    ```
###  Retrieve the content of commands in a note 
If you have a note object, the [commands](/sdk/data-command) for that note can be found using the `commands` attribute on the `Note` instance:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    note_commands = note.commands.all()
    ```
You can also filter commands by their state or other attributes:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    # Get only committed commands
    committed_commands = note.commands.filter(state="committed")
    # Get commands by schema_key (e.g., prescriptions)
    prescriptions = note.commands.filter(schema_key="prescribe")
    ```
To access the content of a command, use the `data` attribute which contains a JSON object with the command's data:
    ```python
    import json
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    for command in note.commands.all():
        # Get the command type
        command_type = command.schema_key
        # Get the command data as a dictionary
        command_data = command.data
        # Pretty print the command data
        print(f"Command Type: {command_type}")
        print(json.dumps(command_data, indent=2))
    ```
For more information about command types and their data structure, see the [Command](/sdk/data-command/) documentation.
###  Retrieve educational materials for a note 
Educational material shared through the Educational Material command is recorded on the note. If you have a note object, those records can be found using the `education_material` reverse relation:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    educational_materials = note.education_material.all()
    ```
###  Understanding the note body structure 
The `body` of a note is a JSON array that represents the structure and layout of the note. It intermixes text content with references to commands:
    ```python
    import json
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    # The body is an array of objects
    print(json.dumps(note.body, indent=2))
    ```
The body array contains objects of two types:
  1. **Text objects** : Represent free-form text content
         ```json
         {"type": "text", "value": "Patient reports feeling better"}
         ```
  2. **Command objects** : Reference commands with their metadata
         ```json
         {
           "type": "command",
           "value": "reasonForVisit",
           "data": {
             "id": 1095,
             "command_uuid": "691123c4-6c7d-415b-880b-2beefab9f64a"
           }
         }
         ```
####  Querying on the body 
`body` is computed on each access rather than stored in a column, because Canvas assembles it from more than one column. That does not change the value you read, but it does limit which query operations can name it:
Operation| Supported| Notes  
---|---|---  
`Note.objects.filter(body=...)`| Yes| Also `exclude()` and `get()`, and lookups nested inside a `Q` object  
`Note.objects.only("body")`| Yes| Loads every column the property reads, so building a body costs no further queries  
`Note.objects.defer("body")`| Yes| Defers all of them  
`Note.objects.values("body")`, `values_list("body")`| No| Raises a `FieldError` telling you to use `only("body")`. No single column holds the value to return  
`Note.objects.order_by("body")`| No| Raises a `FieldError`  
`body` named through a relation| No| For example `Appointment.objects.defer("note__body")` or `filter(note__body=...)`. Query `Note` itself instead  
> **Warning:** Naming `body` through a relation stopped working in the [September 8, 2026 release](/release-notes/1-348-0/). A queryset on another model that defers or filters `note__body` now raises an error. If you were deferring it to keep a large body out of a joined scan, query the notes you need separately with `Note.objects.defer("body")`.
So read the body from a note you already have, or filter notes by it, rather than trying to select it as a value:
    ```python
    from canvas_sdk.v1.data.note import Note
    # Load only the columns the body needs.
    notes = Note.objects.only("body").filter(patient__id="b80b1cdc2e6a4aca90ccebc02e683f35")
    for note in notes:
        print(note.body)
    ```
The `command_uuid` in a command object corresponds to the `id` field of the [Command](/sdk/data-command/) model, allowing you to retrieve the full command data:
    ```python
    from canvas_sdk.v1.data.note import Note
    from canvas_sdk.v1.data.command import Command
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    # Find all command references in the note body
    for item in note.body:
        if item.get("type") == "command":
            command_uuid = item["data"]["command_uuid"]
            command = Command.objects.get(id=command_uuid)
            print(f"Command type: {command.schema_key}")
            print(f"Command data: {command.data}")
    ```
###  Retrieve the audit history for a note 
The audit history for a note can be found using the [`NoteStateChangeEvent`](/sdk/data-note/#notestatechangeevent) model. You can access this model directly or through the `state_history` relation on the note object.
    ```python
    from canvas_sdk.v1.data.note import Note, NoteStateChangeEvent
    note = Note.objects.first()
    # Use the state_history relation
    option_1 = note.state_history.all()
    # Use the note object to filter the QuerySet
    option_2 = NoteStateChangeEvent.objects.filter(note=note)
    # Use the note's UUID to filter the QuerySet, which joins to the note table
    # where the note's dbid column is equal to the note_id column of the note
    # state change event and the note's id column is equal to the note's UUID.
    option_3 = NoteStateChangeEvent.objects.filter(note__id=note.id)
    # Use the note's auto-increment database id to filter the QuerySet by the
    # foreign key column without joining to the notes table.
    option_4 = NoteStateChangeEvent.objects.filter(note_id=note.dbid)
    ```
In the above code sample, options 1, 2, and 4 produce identical SQL queries.
###  Determine if a note is locked 
To see if a note is presently locked, you can use the [`CurrentNoteStateEvent`](/sdk/data-note/#currentnotestateevent) model to check if the current note state is 'Locked'. (See: [NoteState](/sdk/data-note/#notestates) for an explanation of the different note states you might encounter)
    ```python
    from canvas_sdk.v1.data.note import Note, CurrentNoteStateEvent, NoteStates
    note = Note.objects.first()
    # You can retrieve the CurrentNoteStateEvent record for the note and check its
    # state attribute.
    if CurrentNoteStateEvent.objects.get(note=note).state == NoteStates.LOCKED:
        # This note is locked!
        pass
    # You can skip retrieving the record by just checking if a
    # CurrentNoteStateEvent record exists for that note with the state 'Locked'.
    if CurrentNoteStateEvent.objects.filter(note=note, state=NoteStates.LOCKED).exists():
        # This note is locked!
        pass
    ```
###  Retrieve the PDF of a locked note 
Locking a note captures it as a PDF showing the note at the moment of the lock. The file is stored on a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at the [NoteStateChangeEvent](/sdk/data-note/#notestatechangeevent) that recorded the lock, so you get there through the note's state history rather than from the note itself.
Resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the lock event's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, DocumentReferenceStatus
    from canvas_sdk.v1.data.note import Note, NoteStates
    note = Note.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    lock_events = note.state_history.filter(state=NoteStates.LOCKED)
    content_type = ContentType.objects.filter(
        app_label="api", model="notestatechangeevent"
    ).first()
    document = DocumentReference.objects.filter(
        content_type=content_type,
        object_id__in=[event.dbid for event in lock_events],
        status=DocumentReferenceStatus.CURRENT,
    ).first()
    url = document.document_url if document else None
    ```
> **Info:** A note can be locked more than once. Each lock captures its own PDF, and Canvas supersedes the earlier ones — so filter on `CURRENT` for the version that is in force, or drop the status filter to see every captured version. Only encounter, inpatient, and review note types are captured this way; other note types have no PDF.
###  Find all open notes 
You can find all open notes by retrieving the note records with a current state which indicates it can be edited. (See list below)
    ```python
    from canvas_sdk.v1.data.note import Note, CurrentNoteStateEvent, NoteStates
    open_note_states = [
        NoteStates.NEW,
        NoteStates.PUSHED,
        NoteStates.CONVERTED,
        NoteStates.UNLOCKED,
        NoteStates.RESTORED,
        NoteStates.UNDELETED,
    ]
    # This will execute one query per CurrentNoteStateEvent object returned
    open_notes_via_list_comprehension = [event.note for event in CurrentNoteStateEvent.objects.filter(state__in=open_note_states)]
    # This will always execute two queries: one to find the note ids of open
    # notes, and a second query to fetch the note records by the ids returned in the
    # first query
    open_note_ids = CurrentNoteStateEvent.objects.filter(state__in=open_note_states).values_list('note_id', flat=True)
    open_notes_via_multiple_queries = Note.objects.filter(dbid__in=open_note_ids)
    ```
###  Get the current state of a given note 
To get a note's current state, retrieve its [`CurrentNoteStateEvent`](/sdk/data-note/#currentnotestateevent) and check the `state` attribute. If you are trying to assess if the current note state represents that note as being editable, you can call the `editable()` method on the `CurrentNoteStateEvent` object.
    ```python
    from canvas_sdk.v1.data.note import Note, CurrentNoteStateEvent
    note = Note.objects.first()
    current_note_state = CurrentNoteStateEvent.objects.get(note=note).state
    is_editable = current_note_state.editable()
    ```
###  Get the current claim of a given note 
You can retrieve the current claim using the method `get_claim()` presented in the Note object.
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.first()
    claim = note.get_claim()
    ```
###  Get the NoteType of a given note 
To get the note type for a specific note, use the `note_type_version` attribute which provides access to the related `NoteType` object:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    # Get the note type name (e.g., "Office Visit")
    note_type_name = note.note_type_version.name
    # Access other note type attributes
    note_type_display = note.note_type_version.display
    note_type_code = note.note_type_version.code
    note_type_system = note.note_type_version.system
    ```
##  Filtering 
###  By attribute 
Notes can also be filtered by attribute. For example, to get all notes for a patient where the `datetime_of_service` is after a certain date, the following code can be used:
    ```python
    import arrow
    from canvas_sdk.v1.data.note import Note
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="fd2ecd87c26044a6a755287f296dd17f")
    recent_notes = Note.objects.filter(
        patient=patient,
        datetime_of_service__gte=arrow.now().shift(weeks=-3).datetime
    )
    ```
The `NoteType` model can also be used to find notes by type.
    ```python
    from canvas_sdk.v1.data.note import Note
    from canvas_sdk.v1.data.note import NoteType
    from canvas_sdk.v1.data.patient import Patient
    note_type = NoteType.objects.get(name="Office visit")
    patient = Patient.objects.get(id="fd2ecd87c26044a6a755287f296dd17f")
    patient_office_visits = Note.objects.filter(patient=patient, note_type_version=note_type)
    ```

# Observation

Source: https://docs.canvasmedical.com/sdk/data-observation/

##  Introduction 
The `Observation` model represents measurements or assertions made about a patient, such as vital signs, lab results, or other clinical findings.
##  Basic usage 
To get an observation by identifier, use the `get` method on the `Observation` model manager:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    observation = Observation.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the observations for a patient can be accessed with the `observations` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    observations = patient.observations.all()
    ```
If you have a patient ID, you can get the observations for the patient with the `for_patient` method on the `Observation` model manager:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    observations = Observation.objects.for_patient(patient_id)
    ```
##  Codings 
The codings for an observation can be accessed with the `codings` attribute on an `Observation` object:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    from logger import log
    observation = Observation.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in observation.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Components 
The components for an observation can be accessed with the `components` attribute on an `Observation` object:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    from logger import log
    observation = Observation.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for component in observation.components.all():
        log.info(f"name: {component.name}")
        log.info(f"value: {component.value_quantity}")
        log.info(f"unit: {component.value_quantity_unit}")
    ```
###  Component codings 
Component codings can be accessed similarly to codings on the observation, by using the `codings` attribute on an `ObservationComponent` object.
##  Filtering 
Observations can be filtered by any attribute that exists on the model.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    observations = Observation.objects.filter(effective_datetime__gte="2024-11-20")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.observation import Observation
    from canvas_sdk.value_set.v2022.physical_exam import Weight
    observations = Observation.objects.find(Weight)
    ```

# Organization

Source: https://docs.canvasmedical.com/sdk/data-organization/

##  Introduction 
The `Organization` model represents the overall Organization in a Canvas EMR instance. An `Organization` can have multiple related [Practice Locations](/sdk/data-practicelocation).
##  Basic usage 
Canvas instances can contain only a single `Organization` entry. To retrieve the `Organization` entry, you can either query by the organization's name:
    ```python
    from canvas_sdk.v1.data.organization import Organization
    organization = Organization.objects.get(full_name="Medical Organization")
    ```
Or since there will only be one `Organization` in an instance, it can also be fetched by using the `first` method:
    ```python
    from canvas_sdk.v1.data.organization import Organization
    organization = Organization.objects.first()
    ```
##  Attributes

# OrganizationalEntity

Source: https://docs.canvasmedical.com/sdk/data-organizational-entity/

##  Introduction 
The `OrganizationalEntity` model represents an external entity that Canvas references through a generic relation — for example, the [ServiceProvider](/sdk/data-serviceprovider/#service-provider) backing a patient's external care team member. Its `type` indicates which kind of entity it points at, and the `content_type` and `object_id` fields identify the specific record.
The most common use is reaching the external members of a patient's care team. A [CareTeamMembership](/sdk/data-care-team/#careteammembership) with no `staff` is an external member, and its `organizational_entity` links to the `OrganizationalEntity` describing the external provider.
##  Basic usage 
When an `OrganizationalEntity` has a `type` of `Service Provider`, its `service_provider` property resolves to the linked [ServiceProvider](/sdk/data-serviceprovider/#service-provider), giving you access to the provider's contact details — such as `business_fax` — without leaving the plugin:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    external_member = patient.care_team_memberships.filter(staff__isnull=True).first()
    entity = external_member.organizational_entity
    if entity and entity.service_provider:
        print(entity.service_provider.business_fax)
    ```
For entities of any other `type`, the `service_provider` property returns `None`.

# PatientAdministrativeDocument

Source: https://docs.canvasmedical.com/sdk/data-patient-administrative-document/

#  PatientAdministrativeDocument 
The `PatientAdministrativeDocument` model represents patient-facing administrative documents: prior authorizations, advance directives and beneficiary notices, signed consent forms and agreements, insurance and prescription cards, driver's licenses, intake forms, releases of information, powers of attorney, and workers' compensation attachments. Each carries a document file and an optional `DocumentCoding`.
A signed consent form is one of these records: `patient_consents` lists the [PatientConsent](/sdk/data-patient-consent/#signed-consent-documents) records it was signed for. The blank template the patient was sent lives on the consent itself, not here.
##  Basic Usage 
    ```python
    from canvas_sdk.v1.data import PatientAdministrativeDocument
    # Get all administrative documents
    documents = PatientAdministrativeDocument.objects.all()
    # Get a specific record by its id
    document = PatientAdministrativeDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    # Get a patient's administrative documents
    patient_documents = PatientAdministrativeDocument.objects.filter(
        patient__id="1eed3ea2a8d546a1b681a2a45de1d790"
    )
    ```
##  Filtering 
Patient administrative documents can be filtered by any attribute that exists on the model.
###  By patient 
    ```python
    from canvas_sdk.v1.data import PatientAdministrativeDocument, Patient
    patient = Patient.objects.get(id="b80b1cdc2e6a4aca90ccebc02e683f35")
    documents = PatientAdministrativeDocument.objects.filter(patient=patient)
    ```
##  Accessing the document file 
The `document_url` property returns a presigned S3 URL for securely accessing the document file, or `None` when no file is present.
    ```python
    from canvas_sdk.v1.data import PatientAdministrativeDocument
    document = PatientAdministrativeDocument.objects.exclude(document="").first()
    # Returns a presigned S3 URL (valid for 1 hour)
    url = document.document_url
    ```
##  The document reference 
Each record also has a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at it — the record that carries the document's coding, category and status, and that represents it in the FHIR API. `document_url` above is the direct route to the file itself; reach for the document reference when you want that surrounding metadata.
Resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the record's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, PatientAdministrativeDocument
    record = PatientAdministrativeDocument.objects.get(
        id="d2194110-5c9a-4842-8733-ef09ea5ead11"
    )
    content_type = ContentType.objects.filter(
        app_label="api", model="patientadministrativedocument"
    ).first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=record.dbid
    ).first()
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`.
##  Document codings 
The `code` field comes from the document's type, which is drawn from a fixed list rather than set freely — either the type selected in Data Integration, or, when a document is created through the FHIR [DocumentReference](/api/documentreference/) endpoint, the LOINC code supplied in `type.coding`, which must match one of the codes below. Every coding uses the LOINC system (`http://loinc.org`). The document types stored as patient administrative documents are:
Document type| Code| Display  
---|---|---  
Advance Beneficiary Notice| 53243-2| Advanced beneficiary notice  
Advance Directive| 42348-3| Advance directives  
Commercial Driver License| 53245-7| Driver license  
Insurance Card Image| 64290-0| Health insurance card  
Insurer Prior Authorization| 52034-6| Payer letter  
Patient Agreement| 80570-5| Agreement  
Patient Consent Documents| 59284-0| Consent Document  
Power of Attorney| 64298-3| Power of attorney  
Provider Order| 46209-3| Provider orders  
Release of Information Request| 101904-1| Release of Information request  
Uncategorized Administrative Document| 51851-4| Administrative note  
Workers Compensation Documents| 52070-0| Workers compensation attachment  
Disability Form| —| none  
Handicap Parking Permit| —| none  
Medicaid Documents| —| none  
Patient Assistance Documents| —| none  
Patient Intake Form| —| none  
Prescription Card Documents| —| none  
> **Warning:** Six of these document types have no coding assigned, so their `code` is `None`. Filtering on `code` silently excludes them — check for a null `code` if you need to catch every administrative document. Because the FHIR endpoint identifies a document's type by its LOINC code, these six can only be created through Data Integration.
Clinical document types are stored as [UncategorizedClinicalDocument](/sdk/data-uncategorized-clinical-document/) instead. Lab reports, imaging reports and specialist consult reports have their own models, so their codings never appear here.

# PatientConsent

Source: https://docs.canvasmedical.com/sdk/data-patient-consent/

##  Introduction 
The `PatientConsent` model represents documented patient consents in Canvas that ensure legal compliance and protect patient rights. Each `PatientConsent` is linked to a `Patient`, has a category (which is a `PatientConsentCoding`), and optionally a rejection reason (which is a `PatientConsentRejectionCoding`).
##  Usage 
The `PatientConsent` model can be used to find all of the patient consents for a given patient and organization:
    ```python
    >>> from canvas_sdk.v1.data import PatientConsent, Patient, Organization
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> organization_1 = Organization.objects.first()
    >>> patient_1_consents = PatientConsent.objects.filter(patient=patient_1, organization=organization_1)
    >>> print([consent.category.display for consent in patient_1_consents])
    ['Surgical Consent Form', 'Telehealth', 'HIPAA']
    ```
You can also access a patient's consents from the `Patient` model:
    ```python
    >>> from canvas_sdk.v1.data import PatientConsent, Patient
    >>> patient_1 = Patient.objects.get(id="aebe4d3f5d18410388dc69c4b5169fc3")
    >>> patient_1_consents = patient_1.patient_consent.all()
    >>> print([consent.category.display for consent in patient_1_consents])
    ['Surgical Consent Form', 'Telehealth', 'HIPAA']
    ```
And you can also access all of the PatientConsents for a given PatientConsentCoding (aka category):
    ```python
    >>> from canvas_sdk.v1.data import PatientConsentCoding
    >>> coding = PatientConsentCoding.objects.get(code='59284-0', system='LOINC')
    >>> consents = coding.patient_consent.all()
    >>> print([consent.state for consent in consents])
    ['accepted', 'accepted_via_patient_portal', 'rejected']
    ```
Each `PatientConsentCoding` has a `document` field containing the URL to the consent template document:
    ```python
    >>> from canvas_sdk.v1.data import PatientConsentCoding
    >>> coding = PatientConsentCoding.objects.first()
    >>> print(coding.document)
    'consent_templates/hipaa_consent.pdf'
    ```
##  Accessing Document Files 
The `document_url` property returns a presigned S3 URL for securely accessing the blank consent template — the form you send to a patient to collect their consent. The copy the patient signs and returns is a separate record; see Signed consent documents.
    ```python
    from canvas_sdk.v1.data import PatientConsentCoding
    consent_coding = PatientConsentCoding.objects.first()
    # Returns a presigned S3 URL (valid for 1 hour)
    url = consent_coding.document_url
    ```
##  Signed consent documents 
The `PatientConsentCoding.document` above is the blank **template** sent to the patient. The **signed** documents the patient completes and returns are [PatientAdministrativeDocument](/sdk/data-patient-administrative-document/) records, reachable from the consent through the `documents` relation:
    ```python
    from canvas_sdk.v1.data import PatientConsent
    consent = PatientConsent.objects.get(id="8a2b1c3d-4e5f-6a7b-8c9d-0e1f2a3b4c5d")
    # Every signed document attached to this consent.
    signed_documents = consent.documents.all()
    # The current signed document (the most recent non-junked one), or None.
    current = consent.active_document
    ```
Each signed document's FHIR [DocumentReference](/sdk/data-document-reference/) is reachable through `document_references`, so a plugin can read the reference (and its `related_object`) in-process without a FHIR call:
    ```python
    from canvas_sdk.v1.data import PatientConsent
    consent = PatientConsent.objects.get(id="8a2b1c3d-4e5f-6a7b-8c9d-0e1f2a3b4c5d")
    for reference in consent.document_references:
        url = reference.document_url
    ```

# Patient Group

Source: https://docs.canvasmedical.com/sdk/data-patient-group/

##  Introduction 
The `PatientGroup` model represents a named collection of patients. Patients are associated with a group through the `PatientGroupMember` model, which tracks membership along with start/end dates and active status.
##  Basic usage 
To get a patient group by identifier, use the `get` method on the `PatientGroup` model manager:
    ```python
    from canvas_sdk.v1.data.patient_group import PatientGroup
    group = PatientGroup.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
To get the members of a group:
    ```python
    from canvas_sdk.v1.data.patient_group import PatientGroup
    from logger import log
    group = PatientGroup.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for patient in group.members.all():
        log.info(f"Patient: {patient.id}")
    ```
If you have a patient object, the groups that a patient belongs to can be accessed with the `patient_groups` attribute on a [Patient](/sdk/data-patient/#patient) object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    groups = patient.patient_groups.all()
    ```
##  Membership 
The `PatientGroupMember` model represents a patient's membership in a group. To access the membership records for a group:
    ```python
    from canvas_sdk.v1.data.patient_group import PatientGroup, PatientGroupMember
    from logger import log
    group = PatientGroup.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    # Get active members
    active_members = PatientGroupMember.objects.filter(patient_group=group, active=True)
    for membership in active_members:
        log.info(f"Patient: {membership.member.id}, Start: {membership.start_date}")
    ```
##  Filtering 
Patient groups and memberships can be filtered by any attribute that exists on the model.
###  By name 
    ```python
    from canvas_sdk.v1.data.patient_group import PatientGroup
    groups = PatientGroup.objects.filter(name="Diabetes Management")
    ```
###  By active membership 
    ```python
    from canvas_sdk.v1.data.patient_group import PatientGroupMember
    active_memberships = PatientGroupMember.objects.filter(active=True, patient_group__name="Diabetes Management")
    ```

# Patient

Source: https://docs.canvasmedical.com/sdk/data-patient/

##  Introduction 
The `Patient` model represents an individual receiving care or other health-related services.
##  Basic usage 
To get a patient by identifier, use the `get` method on the `Patient` model manager:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="b80b1cdc2e6a4aca90ccebc02e683f35")
    ```
##  Filtering 
Patients can be filtered by any attribute that exists on the model.
Filtering for patients is done with the `filter` method on the `Patient` model manager.
###  By attribute 
Specify attributes with `filter` to filter by those attributes:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patients = Patient.objects.filter(first_name="Bob", last_name="Loblaw", birth_date="1960-09-22")
    ```
##  Accessing the patient photo 
The `photo_url` property returns a presigned S3 URL for securely accessing the patient's uploaded avatar photo. If the patient has no uploaded avatar, the property returns a default avatar URL instead — so the value is always safe to render without a null check.
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="d7af3e356368446c85b40a5d6ff7288e")
    # Returns a presigned S3 URL (valid for 1 hour), or the default avatar URL when no photo is on file
    url = patient.photo_url
    ```
If you need the underlying `PatientPhoto` record (for example, to read the original `url` or `title`), use the `photo` property:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="d7af3e356368446c85b40a5d6ff7288e")
    photo = patient.photo  # PatientPhoto or None
    if photo:
        print(photo.title)
    ```
##  Accessing educational materials 
If you have a `Patient` object, the educational materials recorded on their notes can be accessed with the `education_material` reverse relation:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="d7af3e356368446c85b40a5d6ff7288e")
    educational_materials = patient.education_material.all()
    ```

###  ContactCategory 
A contact-category coding available in this Canvas instance — the set a contact's relationship can be drawn from.
Use this to look up a coding before writing it with the [Patient effect](/sdk/effect-patient/#patientcontactcategory). Writing a coding that does not appear here is rejected rather than created, so querying this model first is how you find out what the instance actually has.

# PayorSpecificCharge

Source: https://docs.canvasmedical.com/sdk/data-payor-specific-charge/

##  Introduction 
The `PayorSpecificCharge` model represents charges specific to a [Transactor](/sdk/data-coverage/#transactor) in Canvas.
##  Usage 
The `PayorSpecificCharge` model can be used to find all of the charges specific to a single `Transactor`:
    ```python
    >>> from canvas_sdk.v1.data import PayorSpecificCharge, Transactor
    >>> aetna = Transactor.objects.get(payer_id="60054")
    >>> aetna_charges = PayorSpecificCharge.objects.filter(transactor=aetna)
    >>> print([charge.charge_amount for charge in aetna_charges])
    [150.00, 40.00, 99.99]
    ```
You can also access a transactor's specific charges from the `Transactor` model:
    ```python
    >>> from canvas_sdk.v1.data import Transactor
    >>> aetna = Transactor.objects.get(payer_id="60054")
    >>> aetna_charges = aetna.specific_charges.all()
    >>> print([charge.charge_amount for charge in aetna_charges])
    [150.00, 40.00, 99.99]
    ```
`

# Plan

Source: https://docs.canvasmedical.com/sdk/data-plan/

##  Introduction 
The `Plan` model represents a Plan (plan of care) recorded on a Note, and is always associated with a Note and a Patient. It is the anchor for the [Plan](/sdk/commands/#plan) command.
##  Basic usage 
To get a plan by identifier, use the `get` method on the `Plan` model manager:
    ```python
    from canvas_sdk.v1.data.plan import Plan
    plan = Plan.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, or note object, the plans for a patient or note can be accessed with the `plans` attribute on a `Patient` or `Note` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    plans = patient.plans.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    plans = note.plans.all()
    ```
##  Reading the narrative 
The plan text is exposed through the `narrative` property:
    ```python
    from canvas_sdk.v1.data.plan import Plan
    plan = Plan.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    text = plan.narrative
    ```
##  Filtering 
Plans can be filtered by any attribute that exists on the model.
###  Committed plans 
The `committed` method returns plans that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.plan import Plan
    committed_plans = Plan.objects.committed()
    ```
##  Attributes

# PluginCommand

Source: https://docs.canvasmedical.com/sdk/data-plugin-command/

##  Introduction 
The `PluginCommand` model exposes the custom commands a plugin registers in its `CANVAS_MANIFEST.json`. Use it to read back a registered command's `label` and `section` instead of reconstructing display text from its camelCase `command_key`.
##  Basic usage 
To get a plugin command by identifier, use the `get` method on the `PluginCommand` model manager:
    ```python
    from canvas_sdk.v1.data.plugin_command import PluginCommand
    plugin_command = PluginCommand.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
##  Filtering 
Plugin commands can be filtered by any attribute that exists on the model.
Filtering for plugin commands is done with the `filter` method on the `PluginCommand` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.plugin_command import PluginCommand
    # Find all plugin commands in a specific chart section
    plugin_commands = PluginCommand.objects.filter(section="assessment")
    ```
###  By command key 
To find a registered command by the key declared in the manifest, filter on `command_key` — or on `schema_key`, which holds the same value:
    ```python
    from canvas_sdk.v1.data.plugin_command import PluginCommand
    plugin_command = PluginCommand.objects.filter(command_key="riskAssessment").first()
    if plugin_command:
        print(f"Label: {plugin_command.label}")
        print(f"Section: {plugin_command.section}")
    ```
##  Attributes 
###  PluginCommand 
Field Name| Type  
---|---  
id| UUID  
dbid| Integer  
name| String  
command_key| String  
schema_key| String  
label| String  
section| String  
plugin_name| String  
  - **id** : The unique UUID identifier for the plugin command.
  - **dbid** : The internal database primary key.
  - **name** : The registered name of the command (e.g., `RiskAssessment`).
  - **command_key** : The command key declared in the plugin's manifest (e.g., `riskAssessment`). There is exactly one row per `command_key`: reinstalling or upgrading the plugin updates that row in place, so a command always carries its current `label` and `section`.
  - **schema_key** : Always equal to `command_key`. It exists as its own field because chart command lines use the same name — see [`Command.schema_key`](/sdk/data-command/#command), which plugin authors query with `Command.objects.filter(schema_key="riskAssessment")`. Two installed plugins cannot declare the same key; the second install fails with a validation error.
  - **label** : The user-friendly display label for the command (e.g., `Risk Assessment`).
  - **section** : The chart section where the command appears: `subjective`, `objective`, `assessment`, `plan`, `procedures`, `history`, or `internal`.
  - **plugin_name** : The name of the plugin that registered the command.

# Practice Location

Source: https://docs.canvasmedical.com/sdk/data-practicelocation/

##  Introduction 
The `PracticeLocation` model lists all the clinical practice locations that fall under an [Organization](/sdk/data-organization).
##  Basic usage 
To query a `PracticeLocation` by name, the `filter` method can be used like so:
    ```python
    from canvas_sdk.v1.data.practicelocation import PracticeLocation
    practice_location = PracticeLocation.objects.filter(full_name__icontains="downtown")
    ```
To retrieve a list of all practice locations:
    ```python
    from canvas_sdk.v1.data.practicelocation import PracticeLocation
    practice_locations = PracticeLocation.objects.all()
    ```
To query addresses that are associated with a `PracticeLocation`, related `PracticeLocationAddress` model instances can be accessed by using the `addresses` attribute. For exmample:
    ```python
    from canvas_sdk.v1.data.practicelocation import PracticeLocation
    practice_location = PracticeLocation.objects.first()
    practice_location_addresses = practice_location.addresses.all()
    ```
Each `PracticeLocation` has location-specific settings that control certain behavior within the EMR application. To retrieve the available settings for a `PracticeLocation` instance, the `settings` attribute can be used to retrieve a list of names:
    ```python
    from canvas_sdk.v1.data.practicelocation import PracticeLocation
    practice_location = PracticeLocation.objects.first()
    available_settings = practice_location.settings.values_list('name', flat=True)
    ```
Additionally, a setting's value can be found by accessing the `value` attribute on the `PracticeLocationSetting`:
    ```python
    from canvas_sdk.v1.data.practicelocation import PracticeLocation
    practice_location = PracticeLocation.objects.first()
    preferred_lab_partner_text = practice_location.settings.get(name="preferredLabPartner").value
    ```
Please note that the content of each `value` field can contain any value that is JSON-serializable, which includes string values. This means that `value` could be any of the Python types `string`, `list` or `dict`.

# PrescriptionChangeRequest

Source: https://docs.canvasmedical.com/sdk/data-prescription-change-request/

##  Introduction 
The `PrescriptionChangeRequest` model represents an incoming Surescripts (NCPDP SCRIPT) request to change a prescription — for example, a generic substitution, a prior-authorization requirement, or a script clarification. Each request carries the raw request payload in its `content` attribute, the medication codings that describe the drug in question (`PrescriptionChangeRequestCoding`), and a reference to the original prescription it relates to.
Because a `PrescriptionChangeRequest` originates from the pharmacy, its `patient`, `note`, and `staff` associations are nullable and may be unset. The provider's approve/deny decision is recorded as a [PrescriptionChangeResponse](/sdk/data-prescription-change-response/), which links back to the request and is available through the request's `response` reverse relation.
##  Basic usage 
To get a prescription change request by identifier, use the `get` method on the `PrescriptionChangeRequest` model manager:
    ```python
    from canvas_sdk.v1.data import PrescriptionChangeRequest
    change_request = PrescriptionChangeRequest.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
##  Related data 
A change request's medication codings are available through the `codings` reverse relation, and the responses recorded against it are available through the `response` reverse relation:
    ```python
    from canvas_sdk.v1.data import PrescriptionChangeRequest
    from logger import log
    change_request = PrescriptionChangeRequest.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    for coding in change_request.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    responses = change_request.response.all()
    ```
The `PrescriptionChangeRequestCoding` entries represent the coding of the medication in question (for example, FDB or RxNorm), with an unstructured fallback whose `display` carries the drug description text when no structured code is available.
##  Message content 
The `message_id` and `content` attributes carry the details of the inbound eRx message.
`message_id` is the eRx (NCPDP SCRIPT / Surescripts) message identifier of the inbound change request.
`content` is a JSON field holding the parsed inbound NCPDP SCRIPT change-request payload. It is a free-form, unstructured representation whose exact shape can vary between messages, typically including the pharmacy, the prescriber as reported by the sender, and the dispensed medication details (drug description, NDC, quantity, and similar). `content` defaults to an empty object (`{}`), so it is safe to call `.get()` on, but individual keys may be absent — plugins should access it defensively.
##  Change types 
The `type_code` attribute identifies the kind of change the pharmacy is requesting:
Code| Description  
---|---  
G| Generic Substitution  
P| Prior Authorization Required  
S| Therapeutic Interchange/Substitution  
D| Drug Use Evaluation  
S| Script Clarification  
OS| Pharmacy is out of stock  
U| Prescriber Authorization  
`S` really does carry two meanings. Canvas maps it to both Therapeutic Interchange/Substitution and Script Clarification, so the two are indistinguishable from `type_code` alone.
The `sub_type_code` attribute further qualifies the request. It is nullable and currently supports:

# PrescriptionChangeResponse

Source: https://docs.canvasmedical.com/sdk/data-prescription-change-response/

##  Introduction 
The `PrescriptionChangeResponse` model is the anchor for the ApproveChange and DenyChange commands — a response to a Surescripts prescription change request, recorded on a Note.
##  Basic usage 
To get a prescription change response by identifier, use the `get` method on the `PrescriptionChangeResponse` model manager:
    ```python
    from canvas_sdk.v1.data import PrescriptionChangeResponse
    response = PrescriptionChangeResponse.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the prescription change responses for a patient can be accessed with the `prescription_change_responses` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    responses = patient.prescription_change_responses.all()
    ```
The same attribute is available on a medication:
    ```python
    from canvas_sdk.v1.data import Medication
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    responses = medication.prescription_change_responses.all()
    ```
##  Committed records 
The `committed` method returns responses that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import PrescriptionChangeResponse
    committed_responses = PrescriptionChangeResponse.objects.committed()
    ```

# Prescription

Source: https://docs.canvasmedical.com/sdk/data-prescription/

##  Introduction 
The `Prescription` model represents a prescription for a medication that has been written for a patient. Prescriptions track the full lifecycle of a medication order, including dosage details, pharmacy information, and electronic prescribing status.
##  Basic usage 
To get a prescription by identifier, use the `get` method on the `Prescription` model manager:
    ```python
    from canvas_sdk.v1.data.prescription import Prescription
    prescription = Prescription.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the prescriptions for a patient can be accessed with the `prescriptions` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    prescriptions = patient.prescriptions.all()
    ```
If you have a patient ID, you can get the prescriptions for the patient with the `for_patient` method on the `Prescription` model manager:
    ```python
    from canvas_sdk.v1.data.prescription import Prescription
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    prescriptions = Prescription.objects.for_patient(patient_id)
    ```
##  Filtering 
Prescriptions can be filtered by any attribute that exists on the model.
Filtering for prescriptions is done with the `filter` method on the `Prescription` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.prescription import Prescription, PrescriptionStatus
    prescriptions = Prescription.objects.filter(status=PrescriptionStatus.OPEN)
    ```
    ```python
    from canvas_sdk.v1.data.prescription import Prescription, PrescriptionResponse
    approved_prescriptions = Prescription.objects.filter(response_type=PrescriptionResponse.APPROVED)
    ```
###  Active prescriptions 
The `active` method returns committed prescriptions that have not been denied:
    ```python
    from canvas_sdk.v1.data.prescription import Prescription
    active_prescriptions = Prescription.objects.active()
    ```
###  Committed prescriptions 
The `committed` method returns prescriptions that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.prescription import Prescription
    committed_prescriptions = Prescription.objects.committed()
    ```

# Procedure

Source: https://docs.canvasmedical.com/sdk/data-procedure/

##  Introduction 
The `Procedure` model represents a procedure performed on or ordered for a patient. It is the data model behind the Perform command, is always associated with a Note and a Patient, and has an optional performing provider. Its CPT (or other) codings are available via `codings`.
##  Basic usage 
To get a procedure by identifier, use the `get` method on the `Procedure` model manager:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure
    procedure = Procedure.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient or note object, the procedures for a patient or note can be accessed with the `procedures` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    procedures = patient.procedures.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    procedures = note.procedures.all()
    ```
If you have a patient ID, you can get the procedures for the patient with the `for_patient` method on the `Procedure` model manager:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    procedures = Procedure.objects.for_patient(patient_id)
    ```
##  Codings 
The codings for a procedure can be accessed with the `codings` attribute on a `Procedure` object:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure
    from logger import log
    procedure = Procedure.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for coding in procedure.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    ```
##  Filtering 
Procedures can be filtered by any attribute that exists on the model.
Filtering for procedures is done with the `filter` method on the `Procedure` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure, ProcedureStatus
    procedures = Procedure.objects.filter(status=ProcedureStatus.COMPLETED)
    ```
###  Committed procedures 
The `committed` method returns procedures that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure
    committed_procedures = Procedure.objects.committed()
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.procedure import Procedure
    from canvas_sdk.value_set.v2022.procedure import Colonoscopy
    procedures = Procedure.objects.find(Colonoscopy)
    ```

# Protocol Current

Source: https://docs.canvasmedical.com/sdk/data-protocol-current/

##  Introduction 
The `ProtocolCurrent` object represents the current state of clinical protocols applied to patients within Canvas. Protocols are typically structured plans or guidelines that outline specific medical interventions, treatments, or care pathways for managing various health conditions. The `ProtocolCurrent` object contains essential information about the protocol's status, associated patient, and relevant clinical details.
##  Basic Usage 
To get a protocol by identifier, use the `get` method on the `ProtocolCurrent` model manager:
    ```python
    from canvas_sdk.v1.data.protocol_current import ProtocolCurrent
    protocol = ProtocolCurrent.objects.get(id="12345678-1234-1234-1234-123456789012")
    ```
##  Filtering 
    ```python
    from canvas_sdk.v1.data.protocol_current import ProtocolCurrent
    protocols = ProtocolCurrent.objects.filter(status="active", patient_id="b80b1cdc2e6a4aca90ccebc02e683f35")

# ProtocolOverride

Source: https://docs.canvasmedical.com/sdk/data-protocol-override/

##  Introduction 
The `ProtocolOverride` model represents an instance of a protocol being snoozed for a patient.
##  Basic usage 
To get a protocol override by identifier, use the `get` method on the `ProtocolOverride` model manager:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    protocol_override = ProtocolOverride.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the protocol overrides for a patient can be accessed with the `protocol_overrides` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    overrides = patient.protocol_overrides.all()
    ```
If you have a patient ID, you can get the protocol overrides for the patient with the `for_patient` method on the `ProtocolOverride` model manager:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    override = ProtocolOverride.objects.for_patient(patient_id)
    ```
##  Filtering 
Protocol overrides can be filtered by any attribute that exists on the model.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    overrides = ProtocolOverride.objects.filter(status="active")
    ```
##  Convenience methods 
The `ProtocolOverride` model manager includes convenience methods for the filters plugins most often apply when working with protocol overrides.
`active` returns the overrides whose `status` is `active`:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    active_overrides = ProtocolOverride.objects.active()
    ```
`adjustments` returns the adjustment overrides (`is_adjustment=True`) for a given protocol key, and `snoozes` returns the snooze overrides (`is_snooze=True`) for a given protocol key:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    adjustments = ProtocolOverride.objects.adjustments("HCC001v1")
    snoozes = ProtocolOverride.objects.snoozes("HCC001v1")
    ```
Each method returns a queryset, so you can chain them with `for_patient`, `committed`, and with one another. For example, to get the active adjustments for a given patient and protocol key:
    ```python
    from canvas_sdk.v1.data.protocol_override import ProtocolOverride
    adjustments = (
        ProtocolOverride.objects
        .for_patient("1eed3ea2a8d546a1b681a2a45de1d790")
        .committed()
        .active()
        .adjustments("HCC001v1")
    )
    ```

# Questionnaire

Source: https://docs.canvasmedical.com/sdk/data-questionnaire/

##  Introduction 
The `Questionnaire` model represents a structured set of questions intended to guide the collection of answers from end-users.
The `Interview` model represents answers to a structured set of questions represented by a `Questionnaire`.
##  Basic usage 
To get a questionnaire or interview by identifier, use the `get` method on the `Questionnaire` or `Interview` model managers:
    ```python
    from canvas_sdk.v1.data.questionnaire import Interview, Questionnaire
    questionnaire = Questionnaire.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    interview = Interview.objects.get(id="75df6d7f-d58d-443b-9fa0-ce43b4d7b2a0")
    ```
If you have a patient object, the interviews for a patient can be accessed with the `interviews` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    interviews = patient.interviews.all()
    ```
If you have a patient ID, you can get the interviews for the patient with the `for_patient` method on the `Interview` model manager:
    ```python
    from canvas_sdk.v1.data.questionnaire import Interview
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    interviews = Interview.objects.for_patient(patient_id)
    ```
##  Questionnaire questions 
The questions for a questionnaire can be accessed with the `questions` attribute on an `Questionnaire` object:
    ```python
    from canvas_sdk.v1.data.questionnaire import Questionnaire
    from logger import log
    questionnaire = Questionnaire.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for question in questionnaire.questions.all():
        log.info(f"system: {question.code_system}")
        log.info(f"code: {question.code}")
        log.info(f"name: {question.name}")
    ```
##  Interview responses 
The interview responses for an interview can be accessed with the `interview_responses` attribute on an `Interview` object:
    ```python
    from canvas_sdk.v1.data.questionnaire import Interview
    from logger import log
    interview = Interview.objects.get(id="75df6d7f-d58d-443b-9fa0-ce43b4d7b2a0")
    for interview_response in interview.interview_responses.all():
        log.info(f"response option: {interview_response.response_option_value}")
    ```
##  Filtering 
Questionnaires and interviews can be filtered by any attribute that exists on the models.
Filtering for questionnaires and interviews is done with the `filter` method on the `Questionnaire` and `Interview` model managers.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.questionnaire import Interview, Questionnaire
    questionnaires = Questionnaire.objects.filter(name="Tobacco")
    interviews = Interview.objects.filter(progress_status="F")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
Filtering by ValueSet works a little differently. The `find` method on the model manager is used to perform `ValueSet` filtering:
    ```python
    from canvas_sdk.v1.data.questionnaire import Questionnaire
    from canvas_sdk.value_set.v2022.assessment import TobaccoUseScreening
    questionnaires = Questionnaire.objects.find(TobaccoUseScreening)
    ```
`Interview` also supports `find`, which returns the interviews whose questionnaire has a code in the value set:
    ```python
    from canvas_sdk.v1.data.questionnaire import Interview
    from canvas_sdk.value_set.v2022.assessment import TobaccoUseScreening
    interviews = Interview.objects.find(TobaccoUseScreening)
    ```
For interviews, `find` matches against the related `Questionnaire` through the `questionnaires` relation. Questionnaires store their code system by name (for example, `"LOINC"`) rather than by URL, and `find` handles this for you. It also composes with `for_patient`:
    ```python

####  Question types 
`type` holds the code for the kind of question the option set describes. It decides how the question renders in a note and which value an answer carries.
`type`| Question| Answer  
---|---|---  
`TXT`| Free text| Text, on the response's `response_option_value`.  
`INT`| Integer| A whole number.  
`DEC`| Decimal| A decimal number.  
`DATE`| Date| A calendar date, picked from a date picker.  
`SING`| Single select| One ResponseOption.  
`MULT`| Multi select| One or more ResponseOption records.  
`TXT` and `DATE` questions are not scored, so they are skipped when a questionnaire calculates a score. Authoring a questionnaire in a plugin sets this through the question's `responses_type` — see [Questionnaires](/sdk/questionnaires/).
> **Warning:** A `DATE` answer is not readable through the data module yet. It is stored on a date column that `InterviewQuestionResponse` does not expose, so `response_option_value` is empty for a date question. Read it over the FHIR API as a `valueDate` on [QuestionnaireResponse](/api/questionnaireresponse/) in the meantime.

# ReasonForVisit

Source: https://docs.canvasmedical.com/sdk/data-reason-for-visit/

##  Introduction 
This page covers three models:
  - `ReasonForVisit` — a Reason for Visit recorded on a note, and the anchor for the [Reason for Visit](/sdk/commands/#reasonforvisit) command.
  - `ReasonForVisitCoding` — the codings on a recorded Reason for Visit.
  - `ReasonForVisitSettingCoding` — the configured codings an instance offers, used to populate the coding field when a Reason for Visit is recorded.
##  ReasonForVisit 
A `ReasonForVisit` is always associated with a note and a patient. To get one by identifier:
    ```python
    from canvas_sdk.v1.data import ReasonForVisit
    rfv = ReasonForVisit.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
From a patient or a note, use the `reasons_for_visit` attribute:
    ```python
    from canvas_sdk.v1.data import Note, Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    reasons = patient.reasons_for_visit.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    reasons = note.reasons_for_visit.all()
    ```
###  Reading the narrative 
The text is exposed through the `narrative` property, which returns the free-text value when there is one and otherwise renders the structured `narrative_json`:
    ```python
    from canvas_sdk.v1.data import ReasonForVisit
    rfv = ReasonForVisit.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    text = rfv.narrative
    ```
###  Committed reasons for visit 
The `committed` method returns records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import ReasonForVisit
    committed = ReasonForVisit.objects.committed()
    ```
###  Codings 
Each `ReasonForVisit` exposes its codings through `codings`:
    ```python
    from canvas_sdk.v1.data import ReasonForVisit
    rfv = ReasonForVisit.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    codings = rfv.codings.all()
    ```
###  Attributes 
####  ReasonForVisit 
Field Name| Type| Description  
---|---|---  
id| UUID| The universally unique identifier for this record.  
dbid| Integer| The database identifier for this record.  
created| DateTime| When the record was created.  
modified| DateTime| When the record was last modified.  
originator| [CanvasUser](/sdk/data-canvasuser)| The user who originated the command.  
committer| [CanvasUser](/sdk/data-canvasuser)| The user who committed the command, if it has been committed.  
entered_in_error| [CanvasUser](/sdk/data-canvasuser)| The user who entered the record in error, if it has been.  
patient| [Patient](/sdk/data-patient/#patient)| The patient the reason for visit was recorded for.  
note| [Note](/sdk/data-note)| The note it was recorded on.  
narrative| String| The reason for visit text.  
codings|  _list_|  The `ReasonForVisitCoding` records on this reason for visit.  
####  ReasonForVisitCoding 
Field Name| Type| Description  
---|---|---  
dbid| Integer| The database identifier for this coding record.  
code| String| The code representing the concept.  
display| String| The human-readable display name for the concept.  
system| String| The coding system.  
version| String| The version of the coding system.  
user_selected| Boolean| Whether a user chose this coding directly.  
reason_for_visit| ReasonForVisit| The reason for visit this coding belongs to.  
##  ReasonForVisitSettingCoding 
The `ReasonForVisitSettingCoding` model represents the coding information used to populate the coding field within a Reason For Visit in Canvas.
###  Basic Usage 
To retrieve a specific coding record by its identifier, use the model manager's `get` method:
    ```python
    from canvas_sdk.v1.data import ReasonForVisitSettingCoding
    rfv_coding = ReasonForVisitSettingCoding.objects.get(id="e2b1e1e3-3f52-4a0a-bb3a-123456789abc")
    ```
You can also filter records by attributes. For example, to get all codings from a specific coding system:
    ```python
    from canvas_sdk.v1.data import ReasonForVisitSettingCoding
    codings = ReasonForVisitSettingCoding.objects.filter(system="http://snomed.info/sct")
    ```
###  Attributes 
####  ReasonForVisitSettingCoding 
Field Name| Type| Description  
---|---|---  
id| UUID| The universally unique identifier for this coding record.  
dbid| Integer| The database identifier for this coding record.  
code| String| The code representing the concept.  
display| String| The human-readable display name for the concept.  
system| String| The coding system (e.g., `http://snomed.info/sct`).  
version| String| The version of the coding system.  
duration| Array of Duration| An array of durations (as Python `timedelta` objects) associated with the coding.  
user_selected| Boolean| The active/inactive flag for this reason-for-visit coding: `True` = active, `False` = inactive.

# Referral

Source: https://docs.canvasmedical.com/sdk/data-referral/

##  Introduction 
The `Referral`, `ReferralReport`, and `ReferralReview` models represent referral results and their reviews.
##  Basic Usage 
To retrieve a `Referral`, `ReferralReport`, or `ReferralReview` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.referral import Referral, ReferralReport, ReferralReview
    referral = Referral.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    referral_report = ReferralReport.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    referral_review = ReferralReview.objects.get(id="b3e6f74c-2a1b-4c8d-9f2e-31842ae7d3b9")
    ```
If you have a patient object, the referrals, reports, and reviews can be accessed with the `referral_set`, `referral_reports`, and `referral_reviews` attributes, respectively on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    referrals = patient.referral_set.all()
    reports = patient.referral_reports.all()
    reviews = patient.referral_reviews.all()
    ```
##  Filtering 
Referrals, reports, and reviews can be filtered by any attribute that exists on the models.
Filtering is done with the `filter` method on the `Referral`, `ReferralReport`, and `ReferralReview` model managers.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.referral import Referral, ReferralReport, ReferralReview
    referrals = Referral.objects.filter(priority="urgent")
    reports = ReferralReport.objects.filter(requires_signature=True)
    reviews = ReferralReview.objects.filter(status="completed")
    ```
###  By ValueSet 
See [Value Sets](/sdk/data-value-sets/) for the library of built-in value sets and how to create your own.
`ReferralReport` supports `ValueSet` filtering through the `find` method on its model manager:
    ```python
    from canvas_sdk.v1.data.referral import ReferralReport
    from canvas_sdk.value_set.v2022.procedure import DialysisServices
    reports = ReferralReport.objects.find(DialysisServices)
    ```
`find` joins through the report's `codings` reverse relation and matches on `(system, code)` pairs from the value set, so a coding must match both the code system and the code to be included.
###  Committed records 
The `committed` method returns `Referral` and `ReferralReview` records that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.referral import Referral, ReferralReview
    committed_referrals = Referral.objects.committed()
    committed_reviews = ReferralReview.objects.committed()
    ```
##  Related Tasks 
To retrieve an Referral's related tasks, use the `get_task_objects` method on the Referral object.
    ```python
    from canvas_sdk.v1.data.referral import Referral
    referral = Referral.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    tasks = referral.get_task_objects().all()
    ```
The `task_list` computed property returns the same related tasks as a `list[Task]`:
    ```python
    from canvas_sdk.v1.data.referral import Referral
    referral = Referral.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    tasks = referral.task_list
    ```
##  The document reference 
`ReferralReport` carries the consult report's specialty, review state and comments, not the file. Canvas stores the file on a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at the report, which is also how it appears in the FHIR API.
To read it, resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the report's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, ReferralReport
    report = ReferralReport.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    content_type = ContentType.objects.filter(app_label="api", model="referralreport").first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=report.dbid
    ).first()
    url = document.document_url if document else None
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`.

# RefillRequest

Source: https://docs.canvasmedical.com/sdk/data-refill-request/

##  Introduction 
The `RefillRequest` model represents an incoming request to refill a patient's medication — for example, a renewal request received electronically from a pharmacy. Each request carries the raw request payload in its `content` attribute, the associated patient and staff member, the medication codings that describe the requested drug (`RefillRequestCoding`), and the prescription(s) written in response.
An incoming `RefillRequest` is routed to a [staff](/sdk/data-staff/#staff) member — the provider expected to respond to it, who becomes the `prescriber` of the responding prescription, not the original requester — and can be marked as `ignored` to drop it from the active refill worklist. Once acted on, the request links to the responding prescription(s) through its `response` attribute, and each [Prescription](/sdk/data-prescription/#prescription) points back to the request through its `refill_request` field. Because the request originates from the pharmacy, and a pharmacy may route it to a provider other than the original prescriber, `staff` is not the requester; it is also nullable, so it may be unset.
##  Basic usage 
To get a refill request by identifier, use the `get` method on the `RefillRequest` model manager:
    ```python
    from canvas_sdk.v1.data.refill_request import RefillRequest
    refill_request = RefillRequest.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
If you have a patient object, the refill requests for a patient can be accessed with the `refill_requests` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    refill_requests = patient.refill_requests.all()
    ```
If you have a patient ID, you can get the refill requests for the patient with the `for_patient` method on the `RefillRequest` model manager:
    ```python
    from canvas_sdk.v1.data.refill_request import RefillRequest
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    refill_requests = RefillRequest.objects.for_patient(patient_id)
    ```
##  Filtering 
Refill requests can be filtered by any attribute that exists on the model.
Filtering is done with the `filter` method on the `RefillRequest` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.refill_request import RefillRequest
    outstanding_requests = RefillRequest.objects.filter(ignored=False)
    ```
The `ignored` attribute is a boolean dismiss flag (default `False`). Marking a request ignored removes it from the active refill worklist and is used to suppress duplicates — for example, a pharmacy re-sending a request. Requests that have already been responded to are excluded from the worklist separately, through their linked `response`. A plugin can filter on `ignored`, but setting it is not available through the data module. The example above returns the active (non-dismissed) requests.
##  Related data 
A refill request's medication codings are available through the `codings` reverse relation, and the prescriptions written in response are available through the `response` reverse relation:
    ```python
    from canvas_sdk.v1.data.refill_request import RefillRequest
    from logger import log
    refill_request = RefillRequest.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    for coding in refill_request.codings.all():
        log.info(f"system:  {coding.system}")
        log.info(f"code:    {coding.code}")
        log.info(f"display: {coding.display}")
    responding_prescriptions = refill_request.response.all()
    ```
The `RefillRequestCoding` entries represent the coding of the requested drug (for example, FDB or RxNorm), with an unstructured fallback whose `display` carries the drug description text when no structured code is available.
##  Message content 
The `message_id` and `content` attributes carry the details of the inbound eRx message.
`message_id` is the eRx (NCPDP SCRIPT / Surescripts) message identifier of the inbound refill-renewal request itself.
`content` is a JSON field holding the parsed inbound NCPDP SCRIPT refill-renewal request payload. It is a free-form, unstructured representation whose exact shape can vary between messages. The information typically available includes:
  - the pharmacy (name, NCPDP ID, phone, address)
  - the prescriber as reported by the sender (name, NPI, SPI, and a sender-supplied identifier)
  - the dispensed and prescribed medication details (drug description, NDC, quantity, days supply, directions, number of refills, substitution allowance, written date, and similar)
  - reference identifiers such as the Rx reference number and the message ID of the original prescription it renews — distinct from this request's own `message_id`
`content` is always a JSON object — it defaults to an empty object (`{}`) when no data was captured — so it is safe to call `.get()` on, but individual keys may be absent. Because the shape is not guaranteed, plugins should access `content` defensively, checking that a key is present before relying on it.

# Remove Allergy Event

Source: https://docs.canvasmedical.com/sdk/data-remove-allergy-event/

##  Introduction 
The `RemoveAllergyEvent` model represents a record of an allergy being removed from a patient's allergy list — the anchor for the [Remove Allergy](/sdk/commands/#removeallergy) command.
##  Basic usage 
To get a remove allergy event by identifier, use the `get` method on the `RemoveAllergyEvent` model manager:
    ```python
    from canvas_sdk.v1.data import RemoveAllergyEvent
    removal = RemoveAllergyEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    ```
If you have a patient object, the remove allergy events for a patient can be accessed with the `removed_allergies` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    removals = patient.removed_allergies.all()
    ```
The same records are reachable from the note they were recorded on, with the `removed_allergies` attribute on a `Note` object:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    removals = note.removed_allergies.all()
    ```
You can also access the removed allergy with the `allergy` attribute:
    ```python
    from canvas_sdk.v1.data import RemoveAllergyEvent
    removal = RemoveAllergyEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    allergy = removal.allergy
    ```
Or for a given allergy, you can access all of its removal events with the `remove_allergy_events` attribute:
    ```python
    from canvas_sdk.v1.data import AllergyIntolerance
    allergy = AllergyIntolerance.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    removals = allergy.remove_allergy_events.all()
    ```
##  Committed records 
The `committed` method returns remove allergy events that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import RemoveAllergyEvent
    committed_removals = RemoveAllergyEvent.objects.committed()
    ```

# Resolve Condition Event

Source: https://docs.canvasmedical.com/sdk/data-resolve-condition-event/

##  Introduction 
The `ResolveConditionEvent` model represents a record of a condition being resolved — the anchor for the [Resolve Condition](/sdk/commands/#resolve-condition) command.
##  Basic usage 
To get a resolve condition event by identifier, use the `get` method on the `ResolveConditionEvent` model manager:
    ```python
    from canvas_sdk.v1.data import ResolveConditionEvent
    resolution = ResolveConditionEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    ```
If you have a patient object, the resolve condition events for a patient can be accessed with the `resolved_conditions` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    resolutions = patient.resolved_conditions.all()
    ```
The same records are reachable from the note they were recorded on, with the `resolved_conditions` attribute on a `Note` object:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    resolutions = note.resolved_conditions.all()
    ```
You can also access the resolved condition with the `condition` attribute:
    ```python
    from canvas_sdk.v1.data import ResolveConditionEvent
    resolution = ResolveConditionEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    condition = resolution.condition
    ```
Or for a given condition, you can access all of its resolutions with the `resolutions` attribute:
    ```python
    from canvas_sdk.v1.data import Condition
    condition = Condition.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    resolutions = condition.resolutions.all()
    ```
##  Committed records 
The `committed` method returns resolve condition events that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import ResolveConditionEvent
    committed_resolutions = ResolveConditionEvent.objects.committed()
    ```
##  Attributes

# ServiceProvider

Source: https://docs.canvasmedical.com/sdk/data-serviceprovider/

##  Introduction 
A `ServiceProvider` is an external provider or organization — someone outside your practice that a patient's care touches. The same record backs every surface in Canvas where an outside provider gets picked:
  - The contact selected as the recipient of a [Refer](/sdk/commands/#refer) command.
  - The imaging center selected on an [Imaging Order](/sdk/commands/#imagingorder) command.
  - An external care team member added to a patient's profile.
  - The recipient of an outbound fax, and the matched sender of an inbound one — Data Integration looks up the sending fax number in the contact directory and links the resulting provider to the incoming document, which is what the `integration_tasks` relation below exposes.
Service providers come from two places. Most are drawn from the shared external contact directory, which is what those surfaces search by default and which you can query yourself with [`GET /contacts/`](/sdk/utils/#searching-for-contacts-and-service-providers). You can also build your own directory: providers created through the [ServiceProvider effect](/sdk/effect-service-provider/) belong to your instance and are flagged with `is_customer_managed`.
Your own providers are not searched automatically. To offer them in one of the surfaces above, handle that surface's search event and return them yourself — see the helpers under Search results below, and [Offering your own providers alongside the directory](/guides/customize-search-results/#offering-your-own-providers-alongside-the-directory) for a worked handler covering all four surfaces.
##  Basic usage 
To retrieve a `ServiceProvider` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.service_provider import ServiceProvider
    service_provider = ServiceProvider.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
To retrieve a service provider from an `ImagingOrder` or a `Referral`
    ```python
    from canvas_sdk.v1.data.imaging import ImagingOrder
    from canvas_sdk.v1.data.referral import Referral
    imaging_order = ImagingOrder.objects.get(id="9d2e0f58-338b-11ec-8d3d-0242ac130003")
    imaging_order_service_provider = imaging_order.imaging_center
    referral = Referral.objects.get(id="9d2e0f58-338b-11ec-8d3d-0242ac130004")
    referral_service_provider = referral.service_provider
    ```
To show a `ServiceProvider` full name or full name with specialty use the properties `full_name` or `full_name_and_specialty`
    ```python
    from canvas_sdk.v1.data.service_provider import ServiceProvider
    service_provider = ServiceProvider.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    full_name = service_provider.full_name
    full_name_and_specialty = service_provider.full_name_and_specialty
    ```
##  Service Provider 
###  Fields 
Name| Type| Description  
---|---|---  
id| UUID| Unique identifier  
dbid| Integer| Internal database identifier  
first_name| String| Provider name, or the organization name  
last_name| String| Empty for organizations  
business_fax| String|   
business_phone| String|   
business_address| String|   
specialty| String| Free text  
practice_name| String|   
notes| String|   
is_active| Boolean| `False` once deactivated; the provider is kept, not deleted  
npi| String| 10 digits  
direct_address| String| Direct address  
is_customer_managed| Boolean| `True` for providers created through the SDK — see below  
science_contact_id| Integer| The shared directory contact this provider came from, or `None` if it came from none. Not a reliable provenance signal on its own — providers that predate this tracking have no value — so use `is_customer_managed` to identify a customer's own providers.  
imaging_orders| QuerySet[[ImagingOrder](/sdk/data-imaging/#imagingorder)]| Imaging orders sent to this provider  
referrals| QuerySet[[Referral](/sdk/data-referral/#referral)]| Referrals sent to this provider  
integration_tasks| QuerySet[[IntegrationTask](/sdk/data-integration-task/#integrationtask)]| Integration tasks associated with this provider  
##  Customer-managed providers 
`is_customer_managed` is `True` for providers created with the [Service Provider effects](/sdk/effect-service-provider/), and `False` for everything else.
    ```python
    from canvas_sdk.v1.data.service_provider import ServiceProvider
    ServiceProvider.objects.filter(is_customer_managed=True, is_active=True)
    ```
This is also how you find an existing customer-managed provider — to get its `id` — before updating or deactivating it with the [Service Provider effects](/sdk/effect-service-provider/).
##  Search results 
Two helpers shape a provider for the provider-search surfaces, so you do not have to build the payloads yourself. Both take an optional list of annotations, shown next to the result.
Method| Use it for  
---|---  
`as_search_result(annotations=None)`| A command's provider search — `Refer to` on Refer, `Imaging center` on Imaging Order  
`as_search_contact(annotations=None)`| The fax recipient and external care team dropdowns  
Both identify the provider, so selecting one attaches to that exact record.
The two helpers return different shapes, and the key casing below matches the serialized payload exactly:
  - `as_search_result(annotations=None)` returns `text`, `value`, `description`, and `annotations` at the top level, plus an `extra.contact` object containing `service_provider_id`, `science_contact_id`, `firstName`, `lastName`, `businessFax`, `businessPhone`, `businessAddress`, `specialty`, `practiceName`, and `notes`.
  - `as_search_contact(annotations=None)` returns a flat object: `id`, `serviceProviderId`, `firstName`, `lastName`, `practiceName`, `specialty`, `businessAddress`, `businessPhone`, `businessFax`, and `annotations`.
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.service_provider import ServiceProvider
    class OwnDirectoryFirst(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.FAX__RECIPIENT__PRE_SEARCH), EventType.Name(EventType.PATIENT_PROFILE__EXTERNAL_CARE_TEAM__PRE_SEARCH)]
        def compute(self):
            term = self.event.context.get("search_term", "").strip()
            if not term:
                return []
            providers = ServiceProvider.objects.filter(
                is_customer_managed=True, first_name__icontains=term
            )
            if not providers:
                return []
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(
                        [
                            provider.as_search_contact(
                                [] if provider.is_active else ["Inactive"]
                            )
                            for provider in providers
                        ]
                    ),
                )
            ]
    ```
Both surfaces reply with the same `AUTOCOMPLETE_SEARCH_RESULTS` effect. Only the event you subscribe to and the helper you call differ.
What you return means different things on each surface:
  - **Contact dropdowns, pre-search** — results replace the search; returning nothing runs the normal search instead.
  - **Command searches, post-search** — an empty list clears the results, so return no effect at all when you have nothing to add.

# Snapshot

Source: https://docs.canvasmedical.com/sdk/data-snapshot/

#  Snapshot Models 
The `Snapshot` and `SnapshotImage` models represent images captured via the Canvas iOS application or uploaded directly through the coverages modal. A `Snapshot` groups related images together, while each `SnapshotImage` represents an individual image with presigned URL support for secure access.
Snapshots are primarily used for storing coverage card images. You can navigate from a `Coverage` to its `Snapshot` via the `snapshot` field, and from a `Snapshot` back to its `Coverage` via the `coverage` reverse relation.
##  Basic Usage 
    ```python
    from canvas_sdk.v1.data import Snapshot, SnapshotImage
    # Get all snapshots
    snapshots = Snapshot.objects.all()
    # Get a specific snapshot
    snapshot = Snapshot.objects.get(dbid=42)
    # Get images for a snapshot
    images = snapshot.images.all()
    # Get all snapshot images
    all_images = SnapshotImage.objects.all()
    # Get all snapshot images for a specific coverage
    from canvas_sdk.v1.data.coverage import Coverage
    coverage = Coverage.objects.get(id="a74592ae8a6c4d0ebe0799d3fb3713d1")
    if coverage.snapshot:
        images = coverage.snapshot.images.all()
        for image in images:
            print(image.image_url)
    ```
##  Accessing Image Files 
The `image_url` property on `SnapshotImage` returns a presigned S3 URL for securely accessing the image file.
    ```python
    from canvas_sdk.v1.data import SnapshotImage
    image = SnapshotImage.objects.exclude(image="").first()
    # Returns a presigned S3 URL (valid for 1 hour)
    url = image.image_url
    ```

# Specialty Report Template

Source: https://docs.canvasmedical.com/sdk/data-specialty-report-template/

##  Introduction 
The `SpecialtyReportTemplate`, `SpecialtyReportTemplateField`, and `SpecialtyReportTemplateFieldOption` models represent the templates used for specialty and referral reports. Templates define the structure of a specialty report, including what fields need to be filled in and what options are available for each field. Each template can be associated with a medical specialty via taxonomy codes.
##  Basic Usage 
To retrieve a `SpecialtyReportTemplate` by identifier, use the `get` method on the model manager:
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    template = SpecialtyReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    ```
To access the fields defined in a template:
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    template = SpecialtyReportTemplate.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    fields = template.fields.all()
    ```
##  Filtering 
Templates can be filtered by any attribute on the models.
###  By active status 
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    active_templates = SpecialtyReportTemplate.objects.active()
    ```
###  By type 
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    # Get custom (user-created) templates
    custom = SpecialtyReportTemplate.objects.custom()
    # Get built-in (system) templates
    builtin = SpecialtyReportTemplate.objects.builtin()
    ```
###  By specialty 
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    # Filter by specialty taxonomy code
    cardiology = SpecialtyReportTemplate.objects.by_specialty("207RC0000X")
    ```
###  By search 
    ```python
    from canvas_sdk.v1.data.specialty_report_template import SpecialtyReportTemplate
    results = SpecialtyReportTemplate.objects.search("cardiology")

# Staff

Source: https://docs.canvasmedical.com/sdk/data-staff/

##  Introduction 
The `Staff` model represents a staff member in a Canvas instance.
To get a `Staff` object by it's identifier, use the `get` method:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    ```
`Staff` objects are commonly used in related models, for example the `Task` model. To see all of a staff member's assigned or created tasks, the following code can be used:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    staff.assignee_tasks.all()
    # <QuerySet [<Task: Task object (3)>]>
    staff.creator_tasks.all()
    # <QuerySet [<Task: Task object (7)>]>
    ```
To show a Staff member's contact points (email, phone, etc.), the `telecom` attribute can be used. For example:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    [(t.system, t.value,) for t in staff.telecom.all()]
    # [('phone', '8005551416'), ('email', 'support@canvasmedical.com')]
    ```
To show a `Staff` full name, credentialed name, the topmost clinical role or top role abbreviation use the properties `full_name`, `credentialed_name`, `top_clinical_role` or `top_role_abbreviation`.
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    staff.full_name
    # Larry Weed
    staff.credentialed_name
    # Larry Weed MD
    staff.top_clinical_role.name
    # Physician
    staff.top_role_abbreviation
    # MD
    ```
When a staff member holds more than one role, `top_clinical_role` looks only at roles in a clinical domain — those whose `domain` is `CLINICAL` or `HYBRID` — and returns the one with the highest `domain_privilege_level`. Administrative roles are never selected, even if they carry a higher privilege level. If the staff member has no clinical or hybrid roles, both `top_clinical_role` and `top_role_abbreviation` are `None`. Because `credentialed_name` appends `top_role_abbreviation`, it reflects the same highest-privilege clinical role.
To get `Staff` licenses.
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    staff.licenses.all()
    # <QuerySet [<StaffLicense: CA License for Larry Weed>]>
    ```
##  Accessing the staff signature 
The `signature_url` property returns a presigned S3 URL for securely accessing the staff member's signature file, when one is on file. If no signature has been uploaded, the property returns `None`.
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="4150cd20de8a470aa570a852859ac87e")
    # Returns a presigned S3 URL (valid for 1 hour) or None
    url = staff.signature_url
    ```

    staff_id = "4150cd20de8a470aa570a852859ac87e"
    staff = Staff.objects.get(id=staff_id)
    for metadata in staff.metadata.all():
        log.info(f"{metadata.key}={metadata.value}")
    ```
`StaffMetadata` is a free-form key/value store on a staff member, mirroring `PatientMetadata`. The `(staff, key)` pair is unique, so a given key has at most one value per staff member; use the [`StaffMetadata` effect](/sdk/effect-staff-metadata/) to upsert it from a plugin.

# Stop Medication Event

Source: https://docs.canvasmedical.com/sdk/data-stop-medication-event/

##  Introduction 
The `StopMedicationEvent` model represents a record of a Stop Medication Event, when a medication is removed from a patient's medication list.
##  Basic usage 
To get a stop medication event by identifier, use the `get` method on the `StopMedicationEvent` model manager:
    ```python
    from canvas_sdk.v1.data import StopMedicationEvent
    stopped_medication = StopMedicationEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    ```
If you have a patient object, the stop medication events for a patient can be accessed with the `stopped_medications` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    stopped_medications = patient.stopped_medications.all()
    ```
You can also access the referenced medication with the `medication` attribute:
    ```python
    from canvas_sdk.v1.data import StopMedicationEvent
    stopped_medication = StopMedicationEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
    medication = stopped_medication.medication
    ```
Or for a given medication, you can access all stop events:
    ```python
    from canvas_sdk.v1.data import Medication
    medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    stopped_medication_events = medication.stopmedicationevent_set.all()
    ```
##  Committed records 
The `committed` method returns stop medication events that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data import StopMedicationEvent
    committed_stop_medication_events = StopMedicationEvent.objects.committed()
    ```
##  Attributes

# Task

Source: https://docs.canvasmedical.com/sdk/data-task/

##  Introduction 
A `Task` represents a to-do item to be addressed. Tasks can be assigned to individual staff members and can also have associated comments and labels.
##  Basic usage 
To get a task by it's identifier, use the `get` method on the `Task` model manager:
    ```python
    from canvas_sdk.v1.data.task import Task
    task = Task.objects.get(id="7895e1db-f8de-4660-a0a3-9e5b43a475c6")
    ```
From a `Patient` object, tasks for the patient can be accessed with the `tasks` attribute:
    ```python
    import arrow
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.task import TaskStatus
    patient = Patient.objects.get(id="36950971cb3e4174ad8b9d365abfd6d0")
    # All tasks for the patient
    tasks_for_patient = patient.tasks.all()
    # Tasks for the patient that are overdue
    tasks_for_patient_overdue = patient.tasks.filter(due__lte=arrow.utcnow().datetime, status=TaskStatus.OPEN)
    ```
`Task` objects are also able to have associated `TaskLabel` objects.
    ```python
    from canvas_sdk.v1.data.task import Task
    task = Task.objects.get(id="7895e1db-f8de-4660-a0a3-9e5b43a475c6")
    [(label.name, label.color,) for label in task.labels.all()]
    # [('Emergent', 'red')]
    ```
`Staff` members are able to leave comments on tasks. These are stored as associated `TaskComment` objects. For example:
    ```python
    from canvas_sdk.v1.data.task import Task
    task = Task.objects.get(id="7895e1db-f8de-4660-a0a3-9e5b43a475c6")
    [(comment.creator, comment.body,) for comment in task.comments.all()]
    # [(<Staff: Sam Jones>, "Please call patient.")]
    ```
###  Note Tasks and Initial Comments 
A `NoteTask` represents the link between a Task command and the `Task` it generates. When a task is created via a Task command, a `NoteTask` record is created that stores the original values entered in the command. Of importance is the **initial comment** that is provided during task creation in the `internal_comment` field.
This is important because `task.comments.all()` only returns manual comments added after the task is created through the interface—it does not include the original comment entered during task creation. To access that initial comment, you need to use the `NoteTask` model.
To get a note task by its identifier:
    ```python
    from canvas_sdk.v1.data.task import NoteTask
    note_task = NoteTask.objects.get(id="a1b2c3d4-e5f6-7890-abcd-ef1234567890")
    print(f"Initial comment: {note_task.internal_comment}")
    ```
From a `Task` object, you can access the associated `NoteTask` to retrieve the initial comment:
    ```python
    from canvas_sdk.v1.data.task import Task
    task = Task.objects.get(id="7895e1db-f8de-4660-a0a3-9e5b43a475c6")
    # Access the NoteTask to get the initial comment
    note_task = task.note_tasks.first()
    if note_task:
        print(f"Initial comment: {note_task.internal_comment}")
        print(f"Original title: {note_task.original_title}")
        print(f"Original assignee: {note_task.original_assignee}")
    ```
Common workflow pattern: handling a TASK_CREATED event and accessing the initial comment:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.task import Task
    class TaskCreatedHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.TASK_CREATED)]
        def compute(self):
            task_id = self.target
            task = Task.objects.get(id=task_id)
            # Get the initial comment from the NoteTask
            note_task = task.note_tasks.first()
            if note_task:
                initial_comment = note_task.internal_comment
                # Use the initial comment for your logic
                self.log(f"Task created with initial comment: {initial_comment}")
    ```
From a `Note` object, note tasks can be accessed with the `note_tasks` attribute:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    note_tasks = note.note_tasks.all()
    for note_task in note_tasks:
        print(f"Task: {note_task.original_title}")
        print(f"Initial comment: {note_task.internal_comment}")
    ```
##  Committed note tasks 
The `committed` method on the `NoteTask` model manager returns note tasks whose underlying Task command has been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.task import NoteTask
    committed_note_tasks = NoteTask.objects.committed()
    ```

# Team

Source: https://docs.canvasmedical.com/sdk/data-team/

##  Introduction 
The `Team` model represents a team of staff members in a Canvas instance.
##  Basic usage 
To get an team by identifier, use the `get` method on the `Team` model manager:
    ```python
    from canvas_sdk.v1.data.team import Team
    team = Team.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a staff object, the teams that a staff is a member of can be accessed with the `teams` attribute on a `Staff` object:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    staff = Staff.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    teams = staff.teams.all()
    ```
##  Team Members 
The members of a team can be access with the `members` attribute on a `Team` object:
    ```python
    from canvas_sdk.v1.data.team import Team
    from logger import log
    team = Team.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for member in team.members.all():
        log.info(f"first_name: {member.first_name}")
        log.info(f"last_name: {member.last_name}")
    ```
##  Reconciling with FHIR 
A team's `group_id` is the same identifier used to represent the team in the [FHIR Group endpoint](/api/group/). Use it to cross-reference a `Team` between the SDK and FHIR.
Given a `Team`, you can use its `group_id` with the [Canvas FHIR client](/sdk/clients-canvas-fhir/) to fetch the corresponding FHIR `Group` payload:
    ```python
    from canvas_sdk.clients.canvas_fhir import CanvasFhir
    from canvas_sdk.v1.data.team import Team
    team = Team.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    # Declare these secrets in the CANVAS_MANIFEST.json and set the values on the
    # plugin configuration page.
    client = CanvasFhir(
        self.secrets["CANVAS_FHIR_CLIENT_ID"],
        self.secrets["CANVAS_FHIR_CLIENT_SECRET"],
    )
    # Use the team's group_id to read the corresponding FHIR Group resource.
    group = client.read("Group", str(team.group_id))
    ```
##  Filtering 
Teams can be filtered by any attribute that exists on the model.
Filtering for teams is done with the `filter` method on the `Team` model manager.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.team import Team
    teams = Team.objects.filter(created__gt="2025-01-01")
    ```
##  Attributes

# Uncategorized Clinical Document

Source: https://docs.canvasmedical.com/sdk/data-uncategorized-clinical-document/

##  Introduction 
The `UncategorizedClinicalDocument` and `UncategorizedClinicalDocumentReview` models represent uncategorized clinical documents and their reviews.
##  Basic Usage 
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument, UncategorizedClinicalDocumentReview
    document = UncategorizedClinicalDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    review = UncategorizedClinicalDocumentReview.objects.get(id="c1a5a35a-4ee2-4a0e-85c0-21739dc8c4a8")
    ```
##  Filtering 
Uncategorized clinical documents and reviews can be filtered by any attribute that exists on the models.
###  By review mode 
Filter documents by their review mode:
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    from canvas_sdk.commands.commands.review import ReviewMode
    documents_to_review = UncategorizedClinicalDocument.objects.filter(review_mode=ReviewMode.REVIEW_REQUIRED)
    ```
###  Unreviewed documents 
To get uncategorized documents that have not been reviewed yet and require a review:
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    from canvas_sdk.commands.commands.review import ReviewMode
    from django.db.models import Q
    unreviewed_documents = UncategorizedClinicalDocument.objects.filter(Q(review_mode=ReviewMode.REVIEW_REQUIRED), (Q(review__committer__isnull=True) | Q(review__entered_in_error__isnull=False)))
    ```
##  Delegations 
A document review can be delegated to another staff member or team. The delegations for a document are available through two accessors:
    ```python
    from canvas_sdk.v1.data import UncategorizedClinicalDocument
    document = UncategorizedClinicalDocument.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
    # The full delegation history, oldest first.
    history = document.delegations
    # The current active delegation, or None when the document is with its owner.
    current = document.active_delegation
    ```
See [DocumentReviewDelegation](/sdk/data-document-review-delegation/) for the delegation model and the `DOCUMENT_DELEGATED` event.
##  Document codings 
The `code` field comes from the document's type, which is drawn from a fixed list rather than set freely — either the type selected in Data Integration, or, when a document is created through the FHIR [DocumentReference](/api/documentreference/) endpoint, the LOINC code supplied in `type.coding`, which must match one of the codes below. Every coding uses the LOINC system (`http://loinc.org`). The document types stored as uncategorized clinical documents are:
Document type| Code| Display  
---|---|---  
Care Management Documents| 91983-7| Care management note  
Clinical Patient Intake Form| 64285-0| Medical history screening form  
Emergency Department Report| 96335-5| Emergency department Summary note  
External Medical Records| 11503-0| Medical records  
Home Care Report| 75503-3| Patient's home Note  
Hospital Discharge Summary| 34105-7| Hospital Discharge summary  
Hospital History and Physical| 47039-3| Hospital Admission history and physical note  
Nursing Home| 34113-1| Nursing facility Note  
Operative Report| 11504-8| Surgical operation note  
Physical Exam Documents| 51848-0| Evaluation note  
Prescription Refill Request| 57833-6| Prescription for medication  
Rehabilitation Report| 34823-5| Physical medicine and rehab Note  
Uncategorized Clinical Document| 34109-9| Note  
In Office Testing Documents| —| none  
> **Warning:** In Office Testing Documents have no coding assigned, so their `code` is `None`. Filtering on `code` silently excludes them, and because the FHIR endpoint identifies a document's type by its LOINC code, they can only be created through Data Integration.
Administrative document types are stored as [PatientAdministrativeDocument](/sdk/data-patient-administrative-document/) instead. Lab reports, imaging reports and specialist consult reports have their own models, so their codings never appear here.
##  The document reference 
`UncategorizedClinicalDocument` carries the document's type, review state and comments, not the file. Canvas stores the file on a [DocumentReference](/sdk/data-document-reference/#the-related-object) pointing back at the record, which is also how the document appears in the FHIR API.
To read it, resolve the [ContentType](/sdk/data-content-type/) at runtime from its stable `app_label` and `model` — never hardcode the per-environment `dbid` — and match `object_id` against the record's `dbid`:
    ```python
    from canvas_sdk.v1.data import ContentType, DocumentReference, UncategorizedClinicalDocument
    record = UncategorizedClinicalDocument.objects.get(
        id="d2194110-5c9a-4842-8733-ef09ea5ead11"
    )
    content_type = ContentType.objects.filter(
        app_label="api", model="uncategorizedclinicaldocument"
    ).first()
    document = DocumentReference.objects.filter(
        content_type=content_type, object_id=record.dbid
    ).first()
    url = document.document_url if document else None
    ```
> **Info:** `object_id` holds the related record's integer `dbid`, not its UUID `id`. A document marked entered-in-error keeps its document reference, with the status carried across, so check `status` if that matters to you.

# Vaccine

Source: https://docs.canvasmedical.com/sdk/data-vaccine/

##  Introduction 
The `Vaccine` model represents an entry in a Canvas instance's vaccine catalog — what a provider can choose when documenting an [Immunize](/sdk/commands/#immunize) command. `VaccineLot` represents a physical lot of one of those vaccines, along with how many doses remain on hand.
##  Basic usage 
A vaccine carries the CPT and CVX codes that identify it. The CVX code is on the vaccine; the CPT codes come from its charges, and those charges are what produce the billing line item when an [Immunize](/sdk/commands/#immunize) command is committed.
    ```python
    from canvas_sdk.v1.data import Vaccine
    vaccine = Vaccine.objects.filter(active=True, cvx_code="135").first()
    print(vaccine.cvx_code, [charge.cpt_code for charge in vaccine.charges.all()])
    # 135 ["90662"]
    ```
Each physical lot of a vaccine tracks how many doses remain, and committing an Immunize command decrements that count:
    ```python
    from canvas_sdk.v1.data import VaccineLot
    lot = VaccineLot.objects.filter(lot_number="LOT-135-001").first()
    print(lot.vaccine.short_name, lot.on_hand_inventory, lot.expiration_date)
    # Fluzone High-Dose 25 2027-06-30
    ```
`mvx_code` holds a CDC MVX manufacturer code. The codes are declared as the field's choices, so Django's display helper resolves the manufacturer name:
    ```python
    from canvas_sdk.v1.data import VaccineLot
    lot = VaccineLot.objects.filter(lot_number="LOT-135-001").first()
    print(lot.mvx_code, "->", lot.get_mvx_code_display())
    # ASZ -> AstraZeneca
    ```
Some instances record a single stock figure on the vaccine itself rather than tracking lots. That value lives in `Vaccine.inventory` as free text and is independent of `VaccineLot.on_hand_inventory`.
##  Filtering 
A vaccine is selectable on a note when it is active **and** carries an active CPT charge. Filtering the same way keeps a plugin in step with what a provider would see:
    ```python
    from datetime import date
    from django.db.models import Q
    from canvas_sdk.v1.data import Vaccine
    today = date.today()
    selectable = Vaccine.objects.filter(
        Q(active=True),
        Q(charges__effective_date__lte=today),
        Q(charges__end_date__isnull=True) | Q(charges__end_date__gte=today),
    ).distinct()
    print([vaccine.short_name for vaccine in selectable])
    # ["Fluzone High-Dose", "Trumenba", "Prevnar 13™"]
    ```
Lots are administrable while they have doses on hand:
    ```python
    from canvas_sdk.v1.data import VaccineLot
    in_stock = VaccineLot.objects.filter(vaccine__cvx_code="135", on_hand_inventory__gt=0)
    print([(lot.lot_number, lot.on_hand_inventory) for lot in in_stock])
    # [("LOT-135-001", 25)]
    ```

# ValueSets

Source: https://docs.canvasmedical.com/sdk/data-value-sets/

##  Introduction 
The Canvas SDK includes a library of built-in Value Sets that can be used within plugins to assist with finding conditions or medications related to Electronic Clinical Quality Measures. Plugin developers can also create their own Value Sets and use them in the same manner as the Canvas built-in `ValueSet` classes.
Built-in Value Sets that can be imported into plugins can be found in the Canvas SDK open source repo [here](https://github.com/canvas-medical/canvas-plugins/tree/main/canvas_sdk/value_set/).
##  Usage 
**Filtering Conditions by Value Set**
Value Set classes can be used directly in the data module to query for conditions that are included within them. For example, to find if a patient has been diagnosed with a condition whose coding falls under a particular Value Set, the `find` method can be used as follows:
    ```python
    from logger import log
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.value_set.v2022.condition import EssentialHypertension
    patient = Patient.objects.get(id="6cbc40b408294a5f9b41f57ba1b2b487")
    patient_essential_hypertension_conditions = patient.conditions.find(EssentialHypertension)
    # The patient has been diagnosed with one or more conditions that match a coding within the EssentialHypertension value set
    if patient_essential_hypertension_conditions:
        for condition in patient_essential_hypertension_conditions:
            log.info(condition.codings.all().values())
    ```
**Filtering Medications by Value Set**
Similar to the `Condition` example above, the `find` method can also utilize Value Set classes to filter `Medication` records that fall under a value set:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.value_set.v2022.medication import DementiaMedications
    from logger import log
    patient = Patient.objects.get(id="6cbc40b408294a5f9b41f57ba1b2b487")
    patient_dementia_medications = patient.medications.find(DementiaMedications)
    if patient_dementia_medications:
        for medication in patient_dementia_medications:
            log.info(medication.codings.all().values())
    ```
**Filtering with more than one Value Set**
Sometimes it may be desirable to filter using more than one Value Set. For example, finding all of a patient's conditions that belong within `EssentialHypertension` _or_ `DiagnosisOfHypertension`. In this case, the `find` supports the pipe (`|`) operator to filter conditions that match the codings in either Value Set:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.value_set.v2022.condition import EssentialHypertension, DiagnosisOfHypertension
    from logger import log
    patient = Patient.objects.get(id="6cbc40b408294a5f9b41f57ba1b2b487")
    patient_hypertension_conditions = patient.conditions.find(EssentialHypertension | DiagnosisOfHypertension)
    if patient_hypertension_conditions:
        for condition in patient_hypertension_conditions:
            log.info(condition.codings.all().values())
    ```
##  Creating Custom Value Sets 
The Canvas SDK allows plugin developers to create their own ValueSet classes that can be used in the same manner as the examples above. To do so, one can import and inherit the base `ValueSet` class:
    ```python
    from canvas_sdk.value_set.value_set import ValueSet
    ```
A new class containing Python sets of coding values can be defined like so:
    ```python
    from canvas_sdk.value_set.value_set import ValueSet
    class MyCustomValueSet(ValueSet):
        VALUE_SET_NAME = "My Custom Value Set"
        ICD10CM = {
            "T2601XA",  # Burn of right eyelid and periocular area, initial encounter
        }
        SNOMEDCT = {
            "284537006",  # Eyelid burn (disorder)
        }
    ```
The valid code system constants that can be used to define sets of codes in Value Sets are:
Name| URL  
---|---  
`CPT`| `http://www.ama-assn.org/go/cpt`  
`HCPCSLEVELII`| `https://coder.aapc.com/hcpcs-codes`  
`CVX`| `http://hl7.org/fhir/sid/cvx`  
`LOINC`| `http://loinc.org`  
`SNOMEDCT`| `http://snomed.info/sct`  
`FDB`| `http://www.fdbhealth.com/`  
`RXNORM`| `http://www.nlm.nih.gov/research/umls/rxnorm`  
`ICD10`| `ICD-10`  
`NUCC`| `http://www.nucc.org/`  
`CANVAS`| `CANVAS`  
`INTERNAL`| `INTERNAL`  
`NDC`| `http://hl7.org/fhir/sid/ndc`  
The following code is an example of a custom `ValueSet` in use within a plugin:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.value_set.value_set import ValueSet
    class MyCustomValueSet(ValueSet):
        VALUE_SET_NAME = "My Custom Value Set"
        ICD10CM = {
            "T2601XA",  # Burn of right eyelid and periocular area, initial encounter
        }
        SNOMEDCT = {
            "284537006",  # Eyelid burn (disorder)
        }
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self):
            patient = Patient.objects.get(id="6cbc40b408294a5f9b41f57ba1b2b487")
            custom_value_set_conditions = patient.conditions.find(MyCustomValueSet)
            for vs in custom_value_set_conditions:
                log.info(vs)
            return []
    ```

# VisualExamFinding

Source: https://docs.canvasmedical.com/sdk/data-visual-exam-finding/

##  Introduction 
The `VisualExamFinding` model represents a visual exam finding captured on a note. Each finding consists of a titled image along with a narrative description of the clinical observation.
##  Basic usage 
To get a visual exam finding by identifier, use the `get` method on the `VisualExamFinding` model manager:
    ```python
    from canvas_sdk.v1.data.visual_exam_finding import VisualExamFinding
    finding = VisualExamFinding.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient object, the visual exam findings for a patient can be accessed with the `visual_exam_findings` attribute on a `Patient` object:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    findings = patient.visual_exam_findings.all()
    ```
If you have a note object, the visual exam findings for that note can be accessed with the `visual_exam_findings` attribute on a `Note` object:
    ```python
    from canvas_sdk.v1.data.note import Note
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    findings = note.visual_exam_findings.all()
    ```
##  Accessing image files 
The `image_url` property returns a presigned S3 URL for securely accessing the image file. The URL is valid for 1 hour.
    ```python
    from canvas_sdk.v1.data.visual_exam_finding import VisualExamFinding
    finding = VisualExamFinding.objects.exclude(image="").first()
    # Returns a presigned S3 URL (valid for 1 hour), or None if no image is set
    url = finding.image_url
    ```
##  Filtering 
Visual exam findings can be filtered by any attribute that exists on the model.
###  By attribute 
Specify an attribute with `filter` to filter by that attribute:
    ```python
    from canvas_sdk.v1.data.visual_exam_finding import VisualExamFinding
    # Get all findings with a specific title
    findings = VisualExamFinding.objects.filter(title="Left forearm")
    ```
###  By patient 
    ```python
    from canvas_sdk.v1.data.visual_exam_finding import VisualExamFinding
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    findings = VisualExamFinding.objects.filter(patient=patient)
    ```
###  Committed findings 
The `committed` method returns visual exam findings that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.visual_exam_finding import VisualExamFinding
    committed_findings = VisualExamFinding.objects.committed()
    ```
##  Attributes 
###  VisualExamFinding

---|---  
id| UUID  
dbid| Integer  
created| DateTime  
modified| DateTime

# VitalSignReading

Source: https://docs.canvasmedical.com/sdk/data-vital-sign-reading/

##  Introduction 
The `VitalSignReading` model is the anchor for the [Vitals](/sdk/commands/#vitals) command — a set of vital-sign readings recorded on a Note for a Patient. The individual measurements (blood pressure, heart rate, temperature, weight, etc.) are stored as related `VitalSign` records, reachable via the `signs` attribute.
##  Basic usage 
To get a vital sign reading by identifier, use the `get` method on the `VitalSignReading` model manager:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    reading = VitalSignReading.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    ```
If you have a patient or note object, the readings can be accessed with the `vital_sign_readings` attribute:
    ```python
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.note import Note
    patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
    readings = patient.vital_sign_readings.all()
    note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
    readings = note.vital_sign_readings.all()
    ```
If you have a patient ID, you can get the readings for the patient with the `for_patient` method:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
    readings = VitalSignReading.objects.for_patient(patient_id)
    ```
##  Reading the individual measurements 
Each `VitalSignReading` has one or more `VitalSign` measurements, accessed with the `signs` attribute. Each `VitalSign` carries the measurement's LOINC code, name, value, and units:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    from logger import log
    reading = VitalSignReading.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for sign in reading.signs.all():
        log.info(f"{sign.sign}: {sign.value} {sign.units} (LOINC {sign.loinc_num})")
    ```
`signs` includes the parts of a composite measurement as well as the measurement itself, so a blood pressure appears three times in the loop above. See Composite measurements to walk only the top-level readings.
##  Filtering 
Vital sign readings can be filtered by any attribute that exists on the model.
###  Committed readings 
The `committed` method returns readings that have been committed and not entered in error:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    committed_readings = VitalSignReading.objects.committed()
    ```

value| String  
units| String  
source| String  
parent| VitalSign — the composite measurement this one is a part of, if any  
children| VitalSign[] — the parts of this measurement, if it is a composite  
##  Composite measurements 
Some measurements are recorded as a whole _and_ as their parts. The whole is stored as one `VitalSign` and each part as another, linked to it by `parent`; the reverse accessor is `children`. A measurement that stands on its own has `parent` set to `None` and no `children`.
The [Vitals](/sdk/commands/#vitals) command produces two of these:
  - `blood_pressure` — the combined reading, parent of the `systole` and `diastole` signs taken from it.
  - `oxygen_saturation` — parent of `inhaled_oxygen_concentration` and `inhaled_oxygen_flow_rate`.
Because the parts sit alongside the whole in `reading.signs`, iterating a reading naively counts a blood pressure three times. Filter on `parent` to walk only the top-level measurements:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    from logger import log
    reading = VitalSignReading.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    for sign in reading.signs.filter(parent__isnull=True):
        parts = ", ".join(f"{part.sign}={part.value}" for part in sign.children.all())
        log.info(f"{sign.sign}: {sign.value} {sign.units}" + (f" ({parts})" if parts else ""))
    ```
##  Sign values 
`VitalSign.sign` holds one of a fixed set of values — the ones below are those a Canvas workflow records. Canvas declares them as a `VitalSignChoices` enumeration internally, but that enumeration is **not** exported to plugins, so compare against the string value directly:
    ```python
    from canvas_sdk.v1.data.vitals import VitalSignReading
    reading = VitalSignReading.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
    weights = [sign for sign in reading.signs.all() if sign.sign == "weight"]
    ```
`sign_description` carries a human-readable label for the same measurement, so prefer it for display and reserve `sign` for matching.
###  Where each value comes from 
Not every value is produced by every workflow, so which ones you see depends on how the vitals were recorded:
  - **The[Vitals](/sdk/commands/#vitals) command** writes `height`, `weight`, `waist_circumference`, `body_temperature`, `blood_pressure`, `systole`, `diastole`, `pulse`, `pulse_rhythm`, `respiration_rate`, `oxygen_saturation`, `inhaled_oxygen_concentration`, `inhaled_oxygen_flow_rate`, `supplemental_oxygen` and `note`. Blood pressure is stored three times over — once as the combined `blood_pressure` reading and once each as `systole` and `diastole`.
  - **A committed pediatric physical exam questionnaire** records `length` and `head_circumference_tape_measure`, taken from the answers carrying those LOINC codes.
Derived measurements are **not** `VitalSign` records. When a height, weight or length is recorded, Canvas calculates BMI from the height and weight and stores the results — the BMI-for-age, head-circumference and weight-for-height percentiles — as [Observation](/sdk/data-observation/) records attached to the reading, because each is computed from more than one measurement. Read them there rather than looking for a `sign`.

# Data

Source: https://docs.canvasmedical.com/sdk/data/

The data module provides you with data to compute on. It provides curated, secure access to both PHI (e.g. patient data) and non-PHI (e.g. staff and practice-level data), representing the current state of your target Canvas instance. The module's classes offer convenience methods and operators that make business logic and clinical logic easy to express with standard terminologies like ICD-10, SNOMED-CT, CPT, and the like.
Data module classes are Django ORM models, which allow easy retrieval of data at runtime through Django's expressive [QuerySet API](https://docs.djangoproject.com/en/5.1/ref/models/querysets/).
Access to these models is **read-only** , and mutations to them are allowed only via use of [Effects](/sdk/effects/) and the FHIR API.
Use the [Custom Data](/sdk/custom-data/) features for creating and maintaining your plugin's own data.

# Default Homepage

Source: https://docs.canvasmedical.com/sdk/default-homepage-effect/

##  Overview 
This allows developers to set a provider's default homepage in Canvas. The default homepage is the page that a provider sees when they log in to Canvas. This effect can be used to set the default homepage to a specific page or a plugin application. For more guidance please reference "[How to set a default homepage for the provider application](/guides/set-default-homepage/)"
    ```python
    from canvas_sdk.effects.default_homepage import DefaultHomepageEffect
    DefaultHomepageEffect(page=DefaultHomepageEffect.Pages.PATIENTS).apply()
    ```
    ```python
    from canvas_sdk.effects.default_homepage import DefaultHomepageEffect
    DefaultHomepageEffect(application_identifier="app_identifier").apply()
    ```
##  Structure 
###  **Pages**
An enumeration of pages that can be set as the default homepage:
Value  
---  
`PATIENTS`  
`SCHEDULE`  
`REVENUE`  
`CAMPAIGNS`  
`DATA_INTEGRATION`  
###  **DefaultHomepage**
A DefaultHomepage effect consists of the following properties:
####  Attributes 
Attribute| Type| Description  
---|---|---  
`page`| `Pages \| None`| Optional page  
`application_identifier`| `str \| None`| Optional application identifier  
If both `page` and `application_identifier` are provided, `application_identifier` will take precedence and the default homepage will be set to the specified application. If neither is provided, the default homepage will be set to the Canvas default homepage.

# Application Notification Badge

Source: https://docs.canvasmedical.com/sdk/effect-application-notification-badge/

Notification badges let your plugin surface a count on an [application](/sdk/handlers-applications/) icon — the small number that indicates, for example, how many unread items are waiting. Badges are shown for applications scoped [`global`](/sdk/handlers-applications/#application-scopes) or [`patient_specific`](/sdk/handlers-applications/#application-scopes) — on their icon in the app drawer, or, when the application sets `show_in_panel`, on the panel alongside the other panel buttons — and for [`provider_menu_item`](/sdk/handlers-applications/#application-scopes) applications, next to their label in the provider menu. Applications in other scopes (`full_chart`, `portal_menu_item`, and the Provider Companion scopes) do not display badges.
There are two ways a badge is set:
  - **On load** — override `compute_notification_badge()` on your `Application` handler to provide the initial count shown when Canvas loads applications. See [Notification Badges](/sdk/handlers-applications/#notification-badges) on the Applications handler page.
  - **Live updates** — emit an `ApplicationNotificationBadge` effect from any event handler to update the count in real time, without the user reloading the page. This is what the rest of this page covers.
##  Setting a badge 
`ApplicationNotificationBadge` is a fluent builder. Construct it with the target application's identifier, optionally `.filter(...)` to target patients, then call `.broadcast(...)` to produce the effect.
Method / Attribute|  | Type| Description  
---|---|---|---  
`application_identifier`| required| String| Passed to the constructor. Must match the application's `class` string declared in `CANVAS_MANIFEST.json` — the `<module path>:<ClassName>` value (identical to the handler's `identifier`). An unknown identifier raises a validation error.  
`count`| required| Integer| Passed to `.broadcast()`. The badge value to display. Must be `>= 0`; a count of `0` clears the badge.  
`staff_ids`| optional| list[String]| Passed to `.broadcast()`. [Staff](/sdk/data-staff/) keys that should see the update.  
`patient_ids`| optional| list[String]| Passed to `.filter()`. [Patient](/sdk/data-patient/) keys whose chart context the update applies to.  
The `application_identifier` is the application's `class` string from `CANVAS_MANIFEST.json` (`<module path>:<ClassName>`). For example, an `InboxApp` defined in `my_plugin/apps/inbox.py` and registered like this:
    ```json
    "applications": [
      {
        "class": "my_plugin.apps.inbox:InboxApp",
        "name": "Inbox",
        "description": "Unread items inbox",
        "icon": "/assets/inbox.png",
        "scope": "global"
      }
    ]
    ```
is targeted by that same `class` string:
    ```python
    from canvas_sdk.effects.application_notification_badge import ApplicationNotificationBadge
    # Set a badge of 3 for a specific staff member.
    ApplicationNotificationBadge("my_plugin.apps.inbox:InboxApp").broadcast(count=3, staff_ids=["staff-id"])
    ```
##  Targeting 
`staff_ids` and `patient_ids` control who sees the update. An empty list means "all" on that axis:
`staff_ids`| `patient_ids`| Who sees the badge  
---|---|---  
set| empty| The listed staff, on any patient (and on global views).  
empty| set| Staff currently viewing the listed patients' charts.  
set| set| The listed staff, but only while viewing the listed patients' charts.  
empty| empty| All staff, all patients (a system-wide update).  
Patients are never subscribers themselves — `patient_ids` scopes the badge to a patient's chart, where staff viewing that chart will see it.
> **Note on "all patients" (empty`patient_ids`):** the update is delivered **live** only to charts a staff member currently has open. Other patients' charts reflect the new value the next time they're loaded, via `compute_notification_badge()`. So for a badge that should read the same across every patient, have `compute_notification_badge()` return a patient-independent count (ignore the patient in `self.event.context`). A push then keeps the open chart live, and the load-time hook covers the rest.
    ```python
    from canvas_sdk.effects.application_notification_badge import ApplicationNotificationBadge
    # Show a badge to staff viewing a specific patient's chart.
    ApplicationNotificationBadge("my_plugin.apps.patient_labs:PatientLabsApp").filter(
        patient_ids=["patient-id"]
    ).broadcast(count=5)
    # Combine: only the on-call provider, and only on this patient's chart.
    ApplicationNotificationBadge("my_plugin.apps.patient_labs:PatientLabsApp").filter(
        patient_ids=["patient-id"]
    ).broadcast(count=1, staff_ids=["staff-id"])
    ```
##  Reacting to events 
The most common pattern is updating a badge in response to a domain event. Here a handler recomputes a staff member's inbox count whenever a task is created and pushes the new value live:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.application_notification_badge import ApplicationNotificationBadge
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.task import Task, TaskStatus
    class InboxBadgeHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.TASK__CREATED)
        def compute(self) -> list[Effect]:
            task = Task.objects.get(id=self.event.target.id)
            assignee = task.assignee
            if not assignee:
                return []
            open_count = Task.objects.filter(assignee=assignee, status=TaskStatus.OPEN).count()
            return [
                ApplicationNotificationBadge("my_plugin.apps.inbox:InboxApp").broadcast(
                    count=open_count,
                    staff_ids=[assignee.id],
                )
            ]
    ```
##  Clearing a badge 
Broadcast a `count` of `0` to remove the badge from the icon:
    ```python
    from canvas_sdk.effects.application_notification_badge import ApplicationNotificationBadge
    ApplicationNotificationBadge("my_plugin.apps.inbox:InboxApp").broadcast(count=0, staff_ids=["staff-id"])
    ```
> **Note:** To set the badge value shown when applications first load (rather than in response to an event), override `compute_notification_badge()` on your `Application` handler. See [Notification Badges](/sdk/handlers-applications/#notification-badges).

# Appointment Labels

Source: https://docs.canvasmedical.com/sdk/effect-appointment-labels/

#  Appointment Label Effects 
The appointment label effects provide programmatic management of labels in Canvas. Labels serve as visual indicators and categorization tools, enabling automated workflows and improved organization for appointments.
##  Overview 
Labels are a powerful way to categorize and track appointments. Canvas supports up to 3 labels per appointment, and these effects allow plugins to automatically manage labels based on business logic.
##  AddAppointmentLabel Effect 
The `AddAppointmentLabel` effect adds one or more labels to an existing appointment.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`appointment_id`| `str`| ID of the appointment to add labels to| Yes  
`labels`| `set[str]`| Set of label names to add (1-3 labels total per appointment)| Yes  
###  apply() → Effect 
Adds the specified labels to the appointment.
####  Returns 
An `Effect` object configured for adding appointment labels.
####  Behavior 
  - Labels are added to the appointment if the total count doesn't exceed 3
  - Labels are automatically sorted for consistency
  - Duplicate labels are ignored (labels are stored as a set)
  - Validates the appointment exists before adding labels
  - Validates label names are non-empty strings
  - Returns an error if adding labels would exceed the 3-label limit
####  Example Usage 
    ```python
    from canvas_sdk.effects.note.appointment import AddAppointmentLabel
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.APPOINTMENT_CREATED)]
        def compute(self):
            # Add labels to an appointment
            effect = AddAppointmentLabel(
                appointment_id="appointment-uuid",
                labels={"URGENT", "FOLLOW_UP"}
            )
            return [effect.apply()]
    ```
If more than three labels are attempted to be added, a `ValidationError` will be raised.
    ```python
    from canvas_sdk.effects.note.appointment import AddAppointmentLabel
    from canvas_sdk.exceptions import ValidationError
    def handle_validation_errors():
        # Example of handling validation errors
        try:
            effect = AddAppointmentLabel(
                appointment_id="invalid-id",
                labels={"LABEL1", "LABEL2", "LABEL3", "LABEL4"}  # Would exceed limit
            )
            return [effect.apply()]
        except ValidationError as e:
            # Handle validation errors
            return []
    ```
* * *
##  RemoveAppointmentLabel Effect 
The `RemoveAppointmentLabel` effect removes one or more labels from an existing appointment.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`appointment_id`| `str`| ID of the appointment to remove labels from| Yes  
`labels`| `set[str]`| Set of label names to remove| Yes  
###  apply() → Effect 
Removes the specified labels from the appointment.
####  Returns 
An `Effect` object configured for removing appointment labels.
####  Behavior 
  - Removes the specified labels from the appointment
  - Non-existent labels are ignored (no error thrown)
  - Validates the appointment exists before removing labels
####  Example Usage 
    ```python
    from canvas_sdk.effects.note.appointment import RemoveAppointmentLabel
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.APPOINTMENT_LABEL_REMOVED)]
        def compute(self):
            # Remove labels from an appointment
            effect = RemoveAppointmentLabel(
                appointment_id="appointment-uuid",
                labels={"CANCELLED", "RESCHEDULED"}
            )
            return [effect.apply()]
    ```
* * *
##  Implementation Details 
###  Label Constraints 
  - **Maximum labels** : 3 labels per appointment (enforced by validation)
  - **Label format** : Labels are strings, automatically sorted for consistency
  - **Uniqueness** : Labels are stored as a set, preventing duplicates
  - **Case sensitivity** : Label names are case-sensitive
###  Validation Messages 
The effects provide clear error messages for common issues:
  - `"Appointment {appointment_id} does not exist"` \- When appointment ID is invalid
  - `"Limit reached: Only 3 appointment labels allowed. Attempted to add {count} label(s) to appointment with {existing} existing label(s)."` \- When label limit would be exceeded
These effects work seamlessly with appointment label events:
  - `APPOINTMENT_LABEL_ADDED` \- Fired when labels are added
  - `APPOINTMENT_LABEL_REMOVED` \- Fired when labels are removed
For more information on these events, see [Appointment Events](/sdk/events/#appointments).

# AppointmentMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-appointment-metadata/

The `AppointmentMetadata` effect provides a flexible key-value storage system for appointment-specific data within the Canvas system. This effect enables the creation and updating of custom metadata entries associated with appointment records. This allows for extensible appointment information storage beyond standard scheduling fields.
##  Overview 
Appointment metadata serves as a powerful extension mechanism for storing custom appointment-related information that doesn't fit within the standard appointment data model. It uses the `.upsert(value)` method to apply a value to the key attributed with the Metadata effect object.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`appointment_id`| `str`| Id of the [Appointment(/sdk/data-appointment/)] record to associate metadata with| Yes  
`key`| `str`| Unique identifier for the metadata entry within the appointment context| Yes  
##  Methods 
###  upsert(value: str) → Effect 
Creates or updates a metadata entry for the specified appointment and key combination.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`value`| `str`| The metadata value to store| Yes  
####  Returns 
An `Effect` object configured for upserting appointment metadata.
####  Behavior 
  - If a metadata entry with the specified key already exists for the appointment, it will be updated with the new value
  - If no entry exists, a new metadata entry will be created
  - The operation is idempotent - repeated calls with the same key and value will not create duplicate entries
##  Implementation Details 
###  Validation 
The effect performs comprehensive validation before execution:
  1. **Appointment Existence Validation** : Verifies that the referenced appointment exists in the system
  - Queries the appointment database to confirm the `appointment_id` corresponds to an existing appointment record
  - Returns a descriptive error if the appointment is not found
  1. **Field Validation** : Ensures all required fields are provided and properly formatted
  - Both `appointment_id` and `key` must be non-empty strings
  - The `value` parameter in the `upsert` method must be provided
###  Data Structure 
The effect payload is structured as JSON with the following schema:
    ```json
    {
      "data": {
        "appointment_id": "appointment-id",
        "key": "metadata-key",
        "value": "metadata-value"
      }
    }
    ```
##  Example Usage 
###  Basic Usage 
    ```python
    from canvas_sdk.effects.appointments_metadata.base import AppointmentsMetadata
    # Create a metadata entry for appointment state
    metadata = AppointmentsMetadata(
        appointment_id="550e8400e29b41d4a716446655440001",
        key="state"
    )
    # Upsert the metadata value
    effect = metadata.upsert("CA")
    ```
##  Best Practices 
###  Key Naming Conventions 
  1. **Use Descriptive Names** : Choose keys that clearly indicate the purpose of the metadata
  - Good: `external_mrn`, `preferred_pharmacy_id`, `risk_score_diabetes`
  - Avoid: `data1`, `temp`, `misc`
  1. **Namespace Your Keys** : When building integrations or modules, prefix keys to avoid collisions
  - Example: `integration_patient_id`, `module_diabetes_last_a1c_date`
###  Value Storage 
  1. **String Serialization** : All values are stored as strings. For complex data types:
         ```python
         import json
         from canvas_sdk.effects.appointments_metadata.base import AppointmentsMetadata
         metadata = AppointmentsMetadata(
             appointment_id="550e8400e29b41d4a716446655440001",
             key="result"
         )
         complex_data = {"scores": [85, 92, 78], "average": 85.0}
         metadata.upsert(json.dumps(complex_data))
         ```
  2. **Boolean Values** : Store as "true" or "false" strings for consistency
         ```python
         from canvas_sdk.effects.appointments_metadata.base import AppointmentsMetadata
         consented = True
         metadata = AppointmentsMetadata(
             appointment_id="550e8400e29b41d4a716446655440001",
             key="boolean_value"
         )
         metadata.upsert("true" if consented else "false")
         ```
##  Notes 
  - Metadata entries are appointment-specific and isolated - the same key can have different values for different appointments
  - There is no built-in versioning; updating a key overwrites the previous value
  - The system does not enforce any schema on metadata values - validation is the responsibility of the implementing code

# Banner Alerts

Source: https://docs.canvasmedical.com/sdk/effect-banner-alerts/

The Canvas SDK allows you to place Banners on the Canvas UI.
##  Adding a Banner Alert 
To add a banner alert, import the `AddBannerAlert` class and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
patient_id| required (if patient_filter is not provided)| String| The id of the [patient](/sdk/data-patient/) the alert should be associated with.  
patient_filter| required (if patient_id is not provided)| String| Patient queryset filters to apply the effect to multiple patients. For example, `{"active": True}` will apply to the effect to all active patients  
key| required| String| An identifier that categorizes the alert.  
narrative| required| String| The content of the alert. Maximum 90 characters.  
placement| required| list[Placement]| List of areas the alert should show.  
intent| optional| Intent| Affects the styling of the alert.  
href| optional| String| If given, the alert will appear as a link to this URL.  
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.banner_alert import AddBannerAlert
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self):
            banner = AddBannerAlert(
                patient_id=self.target,
                key="test-alert",
                narrative="This is only a test.",
                placement=[
                    AddBannerAlert.Placement.CHART,
                    AddBannerAlert.Placement.APPOINTMENT_CARD,
                    AddBannerAlert.Placement.SCHEDULING_CARD,
                ],
                intent=AddBannerAlert.Intent.INFO,
                href="https://docs.canvasmedical.com",
            )
            return [banner.apply()]
    ```
To apply the effect to all active patients when a plugin is created or updated, include the `PLUGIN_CREATED` and/or `PLUGIN_UPDATED` events in the `RESPONDS_TO` list. Additionally, `patient_filter` can be used (instead of `patient_id`) on the `AddBannerAlert` class.
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.banner_alert import AddBannerAlert
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.PATIENT_UPDATED),
            EventType.Name(EventType.PLUGIN_CREATED),
            EventType.Name(EventType.PLUGIN_UPDATED),
        ]
        def compute(self):
            banner = AddBannerAlert(
                key="test-alert",

###  Placement 
This determines where the banner alert appears.
####  `Placement.CHART`
This will place the banner under the patient's name on their chart
![](/assets/images/sdk/banner-alerts/banner_alert_placement_chart.png)
####  `Placement.TIMELINE`
This will place the banner on the top of the patient's timeline of notes in their chart
![](/assets/images/sdk/banner-alerts/banner_alert_placement_timeline.png)
####  `Placement.APPOINTMENT_CARD`
This will appear when you click an appointment on the calendar view
![](/assets/images/sdk/banner-alerts/banner_alert_placement_appointment_card.png)
####  `Placement.SCHEDULING_CARD`
This will appear when you select a patient during the scheduling of an appointment on the calendar view
![](/assets/images/sdk/banner-alerts/banner_alert_placement_scheduling_card.png)
####  `Placement.PROFILE`
This will place the banner under the patient's name on their patient registration page
![](/assets/images/sdk/banner-alerts/banner_alert_placement_profile.png)
###  Intent 
The type or severity of an alert. This will change the appearance of the banner alert.
####  `Intent.INFO`
![](/assets/images/sdk/banner-alerts/banner_alert_intent_info.png)
####  `Intent.WARNING`
![](/assets/images/sdk/banner-alerts/banner_alert_intent_warning.png)
####  `Intent.ALERT`
![](/assets/images/sdk/banner-alerts/banner_alert_intent_alert.png)
##  Removing a Banner Alert 
Removing a banner alert is done wih the `RemoveBannerAlert` class. Create an instance of the class, identifying the key of the alert and the patient id. Return the Effect by calling the `.apply()` method. Both the `key` and `patient_id` attributes are required.
    ```python
    from canvas_sdk.effects.banner_alert import RemoveBannerAlert
    banner_alert = RemoveBannerAlert(
        key='test-alert',
        patient_id="d4c933fe8f6948f6a7d2a42a2641b13b",
    )
    banner_alert.apply()
    ```

# Batch Originate Commands

Source: https://docs.canvasmedical.com/sdk/effect-batch-originate/

##  Overview 
The `BatchOriginateCommandEffect` provides an efficient way to insert multiple commands into a note simultaneously. When you need to create many commands at once, using batch originate significantly improves performance compared to individual originate operations.
**Parameters:**
Attribute| Type| Required| Description  
---|---|---|---  
`commands`| `list`| `true`| List of command instances to batch originate  
`line_number`| `int`| `false`| Which note line the commands land on. Defaults to `-1`, which inserts them at the bottom of the note; set a specific line to target that line instead. Combine with `replace_line=True` to also take over (replace the content of) that line.  
`replace_line`| `bool`| `false`| Replace the content of the target line (the one set by `line_number`) with the originated commands, instead of inserting them as new lines. Defaults to `False`.  
**Returns:**
An `Effect` that can be applied to originate all commands in a single operation.
##  How It Works 
The batch originate effect processes multiple commands in a single operation:
  1. **Command Preparation** : Each command in the list required all necessary fields for `originate`
  2. **Note Update** : The note is updated once with all command UUIDs, rather than updating for each command individually
This approach minimizes database round-trips and improves overall performance.
##  Commit behavior 
`BatchOriginateCommandEffect` originates commands in the **uncommitted (draft)** state only. The batch effect has no `commit` option — every command in the batch is inserted into the note body as a draft.
Batch originating commands in a committed state is **not supported** , by design. The performance benefit of batching comes from collapsing the note update for many draft insertions into a single operation, and committing is a separate, per-command action with no equivalent batch saving.
Whenever a plugin needs to originate more than one command — whether you want them left as drafts or committed — batch origination is the right tool. To end up with committed commands, batch originate the drafts first so the note is updated once, then commit each command individually. Assign each command a `command_uuid` up front so it can be committed after it is originated:
    ```python
    from uuid import uuid4
    # Set command_uuid so each draft can be committed after batch origination
    plan1.command_uuid = str(uuid4())
    diagnose.command_uuid = str(uuid4())
    # One note update for all drafts, followed by a commit per command
    return [
        BatchOriginateCommandEffect(commands=[plan1, diagnose]).apply(),
        plan1.commit(),
        diagnose.commit(),
    ]
    ```
For three commands this performs three originates, **one** note update, and three commits. Collapsing the draft insertions into a single note update is where the performance benefit comes from.
##  Note body automations 
A [note body automation](/sdk/handlers-action-buttons/) is an entry a plugin adds to the note body's "/" command list. When a clinician selects the entry, the automation's `handle()` returns a `BatchOriginateCommandEffect` with `replace_line=True`. In this flow Canvas's note body "/" handling supplies the trigger-line position, so Canvas places the originated commands on the line the clinician typed the trigger on and replaces that line, rather than appending them to the note. The automation doesn't set `line_number` itself. If a plugin omits `replace_line`, it keeps its default of `False`, and the batch follows the effect's normal defaults: the originated commands insert at the bottom of the note (the `line_number=-1` default) rather than taking over the trigger line.
    ```python
    return [
        BatchOriginateCommandEffect(
            commands=[plan],
            replace_line=True,
        ).apply()
    ]
    ```
##  Basic Usage 
    ```python
    from canvas_sdk.commands import (
        PlanCommand,
        HistoryOfPresentIllnessCommand,
        QuestionnaireCommand,
        DiagnoseCommand
    )
    from canvas_sdk.effects.batch_originate import BatchOriginateCommandEffect

    from canvas_sdk.events import EventType
    class Handler(BaseHandler):
        def compute(self):
            note_uuid = str(Note.objects.last().id)
            # Create multiple commands
            plan1 = PlanCommand()
            plan1.narrative = "Order labs for lipid panel"
            plan1.note_uuid = note_uuid
            plan2 = PlanCommand()
            plan2.narrative = "Schedule follow-up in 3 months"
            plan2.note_uuid = note_uuid
            hpi = HistoryOfPresentIllnessCommand()
            hpi.narrative = "Annual wellness visit"
            hpi.note_uuid = note_uuid
            diagnose = DiagnoseCommand()
            diagnose.icd10_code = "E11.9"
            diagnose.note_uuid = note_uuid
            diagnose.background = "Type 2 diabetes mellitus"
            # Add a questionnaire
            questionnaire = QuestionnaireCommand()
            questionnaire.note_uuid = note_uuid
            questionnaire_id = Questionnaire.objects.filter(
                name="Patient Health Questionnaire"
            ).first()
            if questionnaire_id:
                questionnaire.questionnaire_id = str(questionnaire_id.id)
            # Batch originate all commands
            commands_to_originate = [plan1, plan2, hpi, diagnose, questionnaire]
            return [BatchOriginateCommandEffect(commands=commands_to_originate).apply()]
    ```

# Billing Line Items

Source: https://docs.canvasmedical.com/sdk/effect-billing-line-items/

The Canvas SDK allows you to create, update, and remove Billing Line Items from the footer of a note.
##  Adding a Billing Line Item 
To add a billing line item to a note, import the `AddBillingLineItem` class, create an instance of it, and return the `.apply()` method from compute.
Attribute|  | Type| Description  
---|---|---|---  
note_id| required| String| The id of the [Note](/sdk/data-note/) where the line item should be associated.  
cpt| required| String| The billing code to use for the line item.  
units| optional| Integer| The number of units to bill for the code. Defaults to `1` if not provided.  
assessment_ids| optional| list[String]| List of Assessment ids from the note that are relevant to the code, also referred to as "diagnosis pointers".  
modifiers| optional| list[Coding]| The modifiers to create with the billing code.  
**Example:**
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Command, Assessment
    from canvas_sdk.effects.billing_line_item import AddBillingLineItem
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.PERFORM_COMMAND__POST_ORIGINATE)
        ]
        def compute(self) -> list[Effect]:
            command_id = self.target
            command = Command.objects.get(id=command_id)
            note = command.note
            assessments = [
                str(i)
                for i in Assessment.objects.filter(note_id=note.dbid).values_list(
                    "id", flat=True
                )
            ]
            b = AddBillingLineItem(
                note_id=str(note.id),
                cpt="99213",
                units=1,
                assessment_ids=assessments,
                modifiers=[
                    {"code": "25", "system": "http://www.ama-assn.org/go/cpt"},
                    {"code": "59", "system": "http://www.ama-assn.org/go/cpt"},
                ],
            )
            return [b.apply()]
    ```
You don't set the line item's description in your plugin. When the line item is created, Canvas matches the `cpt` to a [ChargeDescriptionMaster](/sdk/data-charge-description-master/) charge and populates the description from that charge's `short_name`, truncated to 255 characters. If no charge matches the `cpt`, the description is left empty.

            )
            assessment = Assessment.objects.filter(note_id=note.dbid).first()
            updates = [

                )
                for b_id in b_ids
            ]
            return [update.apply() for update in updates]
    ```
##  Removing a Billing Line Item 
To remove a billing line item to a note, import the `RemoveBillingLineItem` class, create an instance of it, and return the `.apply()` method from compute.

        ]
        def compute(self) -> list[Effect]:
            command_id = self.target
            command = Command.objects.get(id=command_id)
            cpt = command.data["perform"]["value"]
            note_id = command.note.dbid
            b_ids = BillingLineItem.objects.filter(cpt=cpt, note_id=note_id).values_list(
                "id", flat=True
            )
            return [

# Claim Effects

Source: https://docs.canvasmedical.com/sdk/effect-claims/

The Canvas SDK provides effects to facilitate managing claims. The `ClaimEffect` class provides a unified interface for:
  - adding labels to claims
  - removing labels from claims
  - moving claim to a queue
  - adding comments to claims
  - posting payments to claims
  - upserting metadata on claims
  - adding banner alerts to claims
  - removing banner alerts from claims
  - updating provider information on claims
  - updating the supervising provider on claims
  - setting the incident-to flag on claims
Additionally, the SDK provides a separate effect to update claim line items.
The following standalone effect classes are deprecated and will be removed in a future release. Please use the `ClaimEffect` class instead.
Deprecated Class| Old Import Path| New Equivalent  
---|---|---  
`AddClaimLabel`| `canvas_sdk.effects.claim_label`| `ClaimEffect.add_labels()`  
`RemoveClaimLabel`| `canvas_sdk.effects.claim_label`| `ClaimEffect.remove_labels()`  
`MoveClaimToQueue`| `canvas_sdk.effects.claim_queue`| `ClaimEffect.move_to_queue()`  
`AddClaimComment`| `canvas_sdk.effects.claim_comment`| `ClaimEffect.add_comment()`  
`PostClaimPayment`| `canvas_sdk.effects.payment`| `ClaimEffect.post_payment()`

`method`| `PaymentMethod`| The PaymentMethod used (e.g., `cash`, `check`, `card`, `other`).| Yes  
`move_to_queue_name`| `str`| Name of the queue to move the claim to after payment.| No  
`claim_description`| `str`| Description for the claim allocation.| No  
`check_date`| `date`| Date of the check (required if method is `check`).| No  
`check_number`| `str`| Check number (required if method is `check`).| No  
`deposit_date`| `date`| Date the payment was deposited.| No  
`payment_description`| `str`| Description of the payment.| No  
####  Validations and Implementation Details 
  - `check_number` and `check_date` are required if payment method is `check`
  - `claim_id` must correspond to a valid existing claim. For insurance payments, there are a few ways to help you identify the correct claim using the [Claim](/sdk/data-claim/#claim), [ClaimSubmission](/sdk/data-claim/#claimsubmission), [ClaimCoverage](/sdk/data-claim/#claimcoverage) data models:
    - `Claim.account_number` is the identifier that Canvas sends to the clearinghouse as a unique Canvas identifier for the claim.
    - `ClaimSubmission.clearinghouse_claim_id` is the identifier that the clearinghouse sends back to Canvas after they have accepted the claim, and is used for the clearinghouse's internal tracking of the claim.
    - `ClaimCoverage.payer_icn` is the identifier that the insurance company uses for their internal tracking of the claim, and is usually provided to Canvas via the clearinghouse.
  - `claim_coverage_id` must be either the string `"patient"` or correspond to a valid and **active** [ClaimCoverage](/sdk/data-claim/#claimcoverage) for the Claim.
    - A helpful way to identify the correct claim coverage is to use the method `get_coverage_by_payer_id(payer_id: str, subscriber_number: str | None = None)` on the [Claim](/sdk/data-claim/#claim) data model, where `payer_id` is the standard id for the insurance company. You can optionally provide `subscriber_number` if it's possible that the patient has multiple coverages from the same payer and you want to identify the correct coverage.
  - `move_to_queue_name` must be a valid label from [ClaimQueue](/sdk/data-claim/#claimqueues), but is not required. If provided, the claim will move to this queue after payment is applied.
####  LineItemTransaction 
Attribute| Type| Description| Required  
---|---|---|---  
`claim_line_item_id`| `UUID` or `str`| Identifier for the claim line item.| Yes  
`charged`| `Decimal`| Charged amount for the line item.| No  
`allowed`| `Decimal`| Allowed amount for the line item.| No  
`payment`| `Decimal`| Payment amount for the line item.| No  
`adjustment`| `Decimal`| Adjustment amount for the line item.| No  
`adjustment_code`| `str`| Code describing the adjustment.| No  
`transfer_remaining_balance_to`| `UUID`, `str`, or `'patient'`| Transfer remaining balance to another payer or patient.| No  
`write_off`| `bool`| Whether to write off the remaining balance.| No  
#####  LineItemTransaction Validations 
  - `claim_line_item_id` must be a valid and **active** line item for the claim. It is recommended to search for it using `.active()` and by `proc_code`, e.g. `claim.line_items.active().filter(proc_code="99215").first()`
  - There can be many LineItemTransactions for the same `claim_line_item_id`, but the first LineItemTransaction for a claim line item must specify either a payment or an adjustment (or allowed amount); subsequent transactions require an adjustment.
  - If an `adjustment` is specified, an `adjustment_code` must also be provided.
  - If the adjustment code is for a transfer (code starts with "Transfer"), a valid `transfer_remaining_balance_to` must be provided, and it cannot be the same payer as the `claim_coverage_id` payer.
  - `transfer_remaining_balance_to` can only be made to the patient (using the string `"patient"`) or to an **active** `claim_coverage_id` for the claim.
  - Adjustments cannot simultaneously write off and transfer the same amount; only one of `write_off` or `transfer_remaining_balance_to` should be set on LineItemTransactions where `adjustment` is present.
  - Adjustments and transfers are not allowed for COPAY charges, i.e. claim line items where the proc_code = `COPAY`. Only payments are allowed for those line items.
  - `payment` on COPAY line items must have a `claim_coverage_id` equal to `"patient"`.
  - `allowed` should be empty or $0 if `claim_coverage_id` is equal to `"patient"`.
####  PaymentMethod Enumeration Type 
Enum| Value  
---|---  
`CASH`| cash  
`CHECK`| check  
`CARD`| card  
`OTHER`| other

###  Upsert Metadata 
`ClaimEffect.upsert_metadata()`: upserts a key-value metadata record on a claim. If a metadata record with the given key already exists for the claim, its value will be updated. Otherwise, a new metadata record will be created.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`key`| `str`| The key of the metadata| Yes  
`value`| `str`| The value of the metadata| Yes  
####  Implementation Details 
  - Validates `claim_id` is provided and that the associated claim exists
  - The claim-key pair is unique; upserting with an existing key will update the value rather than creating a duplicate
  - If a metadata record already exists with the same claim, key, and value, no update is performed
####  Example Usage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.claim import ClaimEffect
    from canvas_sdk.v1.data import Note
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self) -> list[Effect]:
            """When a note is locked, store the lock timestamp as metadata on the claim."""
            note = Note.objects.get(id=self.event.context["note_id"])
            claim = note.get_claim()
            state = self.event.context["state"]
            if state == "LKD":
                claim_effect = ClaimEffect(claim_id=claim.id)
                return [claim_effect.upsert_metadata(key="locked_at", value=str(note.modified))]
            return []
    ```
###  Add Banner 
`ClaimEffect.add_banner()`: adds a banner alert to a claim. Banner alerts are displayed in the UI to surface important information about a claim.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`key`| `str`| A unique key identifying the banner alert| Yes  
`narrative`| `str`| The banner text to display (max 90 characters)| Yes  
`intent`| BannerAlertIntent| The visual intent/severity of the banner| Yes  
`href`| `str`| An optional link URL for the banner| No  
####  BannerAlertIntent Enumeration Type 
Enum| Value  
---|---  
`INFO`| info  
`WARNING`| warning  
`ALERT`| alert  
####  Implementation Details 
  - Validates `claim_id` is provided and that the associated claim exists
  - The `narrative` field has a maximum length of 90 characters
####  Example Usage

        def compute(self) -> list[Effect]:
            """When a note is unlocked, add a warning banner to the claim."""
            note = Note.objects.get(id=self.event.context["note_id"])
            claim = note.get_claim()
            state = self.event.context["state"]
            if state == "ULK":
                claim_effect = ClaimEffect(claim_id=claim.id)
                return [
                    claim_effect.add_banner(
                        key="review-needed",
                        narrative="This claim needs review before resubmission.",
                        intent=BannerAlertIntent.WARNING,
                    )
                ]
            return []
    ```
###  Remove Banner

####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`key`| `str`| The unique key of the banner alert to remove| Yes  
####  Implementation Details 
  - Validates `claim_id` is provided and that the associated claim exists
####  Example Usage 
    ```python

###  Update Supervising Provider 
`ClaimEffect.update_supervising_provider()`: sets the supervising provider snapshot on a claim. This snapshot is captured for billing purposes (837P loop 2310D and the printed CMS-1500 form) and remains frozen after submission.
Provide exactly one of:
  - A `staff_id` to populate the snapshot from an existing Staff record (name, NPI, taxonomy, tax ID). The snapshot remains linked to the Staff record.
  - A `ClaimSupervisingProvider` dataclass to specify the snapshot fields directly. This clears any Staff association.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`supervising_provider`| ClaimSupervisingProvider or `None`| Free-text provider snapshot| Yes (if `staff_id` not given)  
`staff_id`| `str` or `None`| Staff identifier to populate from| Yes (if `supervising_provider` not given)  
####  ClaimSupervisingProvider 
The `ClaimSupervisingProvider` dataclass represents a supervising provider's identifying information for billing purposes.
Attribute| Type| Description  
---|---|---  
`first_name`| `str` or `None`| First name (max 255 chars)  
`last_name`| `str` or `None`| Last name (max 255 chars)  
`middle_name`| `str` or `None`| Middle name (max 255 chars)  
`npi`| `str` or `None`| NPI number (max 10 chars)  
`taxonomy`| `str` or `None`| Taxonomy code (max 100 chars)  
`tax_id`| `str` or `None`| Tax ID (max 100 chars)  
`tax_id_type`| `str` or `None`| Tax ID type (max 1 char)  
####  Implementation Details 
  - Validates `claim_id` is provided and that the associated claim exists
  - Validates that exactly one of `staff_id` or `supervising_provider` is provided
  - If `staff_id` is provided, validates that the Staff record exists
####  Example Usage 
Using a Staff record:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.claim import ClaimEffect
    from canvas_sdk.v1.data import Note
    class SupervisingProviderHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self) -> list[Effect]:
            """When a note is locked, set the supervising provider from the note's supervising provider."""
            note = Note.objects.get(id=self.event.context["note_id"])
            claim = note.get_claim()
            state = self.event.context["state"]
            if state == "LKD" and note.supervising_provider:
                claim_effect = ClaimEffect(claim_id=claim.id)
                return [claim_effect.update_supervising_provider(staff_id=str(note.supervising_provider.id))]
            return []
    ```
Using free-text provider information:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.claim import ClaimEffect, ClaimSupervisingProvider
    from canvas_sdk.v1.data import Note
    class SupervisingProviderHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self) -> list[Effect]:
            """When a note is locked, set a custom supervising provider on the claim."""
            note = Note.objects.get(id=self.event.context["note_id"])
            claim = note.get_claim()
            state = self.event.context["state"]
            if state == "LKD":
                claim_effect = ClaimEffect(claim_id=claim.id)
                return [
                    claim_effect.update_supervising_provider(
                        ClaimSupervisingProvider(
                            first_name="Jane",
                            last_name="Doe",
                            npi="1234567890",
                            taxonomy="207Q00000X",
                        )
                    )
                ]
            return []
    ```
###  Set Incident To 
`ClaimEffect.set_incident_to()`: sets the `incident_to` billing flag for Medicare incident-to billing. When set to `True`, the claim's rendering provider fields (name, NPI, taxonomy) are automatically replaced with the supervising provider's details.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`value`| `bool`| Whether the claim is billed incident-to the supervising physician| Yes  
####  How Incident-To Billing Works 
When a claim is marked as incident-to:
  1. **Automatic rendering provider swap** : The rendering provider fields (first name, last name, middle name, NPI, and taxonomy) are replaced with the supervising provider's values. This swap happens immediately when `incident_to` is set to `True`, not at claim submission.
  2. **Billing provider unchanged** : The billing provider information (NM1 _85 on the 837P) remains unchanged. Only the rendering provider (NM1_ 82 / Box 24J) is affected.
  3. **Frozen after submission** : Once a claim has been submitted to the clearinghouse, the rendering provider swap no longer occurs even if incident-to settings change.
  4. **Re-sync on supervising provider change** : If the supervising provider is updated on an incident-to claim, the rendering provider fields are automatically re-synced to match the new supervising provider.
####  Printed CMS-1500 Form 
The supervising provider appears on the printed CMS-1500 (HCFA) form differently depending on whether the claim is marked incident-to:
Scenario| Box 24J (Rendering NPI)| Box 17 (Referring/Supervising Provider)  
---|---|---  
**Incident-to claim**|  Supervising provider's NPI (via the automatic rendering swap)| Not populated for supervising—the provider already appears in Box 24J  
**Non-incident-to claim with supervising provider**|  Original rendering provider's NPI| Supervising provider with **DQ** qualifier (if no referring or ordering provider exists)  
For non-incident-to claims with a supervising provider who has a valid NPI and no referring or ordering provider, the printed form populates Box 17 with the supervising provider's name, Box 17a with the "DQ" (supervising physician) qualifier, and Box 17b with the supervising provider's NPI.
Box 17 follows a priority order: referring provider (DN) takes precedence over ordering provider (DK), which takes precedence over supervising provider (DQ). The supervising provider only appears in Box 17 when no referring or ordering provider is present.
####  Claim Errors 
The following errors prevent claim submission when incident-to is enabled:
Error| Description| Solution  
---|---|---  
Missing supervising provider| The claim is marked incident-to but has no supervising provider with an NPI.| Add a supervising provider with a valid NPI, or disable incident-to.  
Supervising provider same as rendering| The supervising provider is the same as the note's original rendering provider.| Set the supervising provider to a different physician, or disable incident-to.  
####  Claim Warnings 
The following warnings are displayed for incident-to claims but do not prevent submission:
Warning| Description| Guidance  
---|---|---  
Non-office place of service| The place of service is not office (11). Incident-to billing is generally not valid in facility settings per 42 CFR 410.26.| Confirm the place of service is correct, or disable incident-to if it does not apply.  
Non-Medicare payer| The payer is not Medicare. Incident-to rules are a Medicare policy; coverage varies by commercial payer.| Confirm the payer accepts incident-to billing, or disable incident-to if it does not apply.  
####  Implementation Details 
  - Validates `claim_id` is provided and that the associated claim exists
  - The rendering provider swap requires a valid supervising provider with an NPI
  - The swap is skipped if the supervising provider's NPI is missing or invalid
####  Example Usage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects.claim import ClaimEffect
    from canvas_sdk.v1.data import Note
    class IncidentToHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.CLAIM_SUPERVISING_PROVIDER_CHANGED)
        def compute(self) -> list[Effect]:
            """When a supervising provider is set on a claim, enable incident-to billing."""
            claim_id = self.event.target.id
            claim_effect = ClaimEffect(claim_id=claim_id)
            return [claim_effect.set_incident_to(True)]
    ```

##  UpdateClaimLineItem 
The `UpdateClaimLineItem` effect allows you to update the `charge` field and `linked_diagnosis_codes` on a specified claim line item.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`claim_line_item_id`| `UUID` or `str`| Identifier for the claim line item| Yes  
`charge`| `float`| The charge amount to update on the claim line item| No  
`linked_diagnosis_codes`| `list[UUID or str]`| List of [ClaimLineItemDiagnosisCode](/sdk/data-claim/#claimlineitemdiagnosiscode) IDs to link to the claim line item| No  
###  Implementation Details 
  - Validates `claim_line_item_id` is provided and that the associated claim line item exists
  - If `linked_diagnosis_codes` is provided, validates that all [ClaimLineItemDiagnosisCode](/sdk/data-claim/#claimlineitemdiagnosiscode) IDs correspond to existing diagnosis codes on the claim line item
  - The `linked_diagnosis_codes` list represents the complete set of diagnosis codes that will be linked to the claim line item when the effect is applied. Any diagnosis codes not included in this list will be unlinked. If you wish to add a new code to the existing linked codes, you must first retrieve the current list and include all codes you want to remain linked: `list(claim_line_item.diagnosis_codes.filter(linked=True).values_list("id", flat=True)) + [new_code_id]`
###  Example Usage 
Updating charge amount.

        def get_line_items(self) -> ClaimLineItem:
            note = Note.objects.get(id=self.event.context["note_id"])
            claim = note.get_claim()
            return claim.get_active_claim_line_items()
        def update_charge(self, id: str, charge: float) -> Effect:
            return UpdateClaimLineItem(claim_line_item_id=id, charge=charge).apply()
        def update_all_items(self, charge: float) -> list[Effect]:
            return [self.update_charge(line_item.id, charge) for line_item in self.get_line_items()]
        def compute(self) -> list[Effect]:
            if self.event.context["state"] == "ULK":
                return self.update_all_items(0.00)
            if self.event.context["state"] == "LKD":

# CommandMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-command-metadata/

The `upsert_metadata` method on any command class provides a flexible key-value storage system for command-specific data within the Canvas system. This method enables the creation and updating of custom metadata entries associated with command records, allowing for extensible command information storage beyond standard command fields.
##  Overview 
Command metadata serves as a powerful extension mechanism for storing custom command-related information that doesn't fit within the standard command data model. Metadata is managed through the `upsert_metadata` method available on all command effect classes.
Metadata can be written two ways, and they store to the same place:
  - **From your plugin** , with the `upsert_metadata` method documented on this page.
  - **From the note** , with the [Command Metadata Create form effect](/sdk/command-metadata-create-form-effect/), which displays additional fields alongside a command in the chart and stores whatever a user enters as metadata against that command.
Either way, the entries are readable as [CommandMetadata](/sdk/data-command/#commandmetadata) in the data module.
##  Method 
###  upsert_metadata(key: str, value: str) → Effect 
Creates or updates a metadata entry for the specified command.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`key`| `str`| Unique identifier for the metadata entry within the command context| Yes  
`value`| `str`| The metadata value to store| Yes  
####  Prerequisites 
The command effect must be initialized with a `command_uuid`. This can be either the UUID of an existing command or the UUID of a command being originated in the same effect list.
Attribute| Type| Description| Required  
---|---|---|---  
`command_uuid`| `str`| Id of the command record to associate metadata with| Yes  
####  Returns 
An `Effect` object configured for upserting command metadata.
####  Behavior 
  - If a metadata entry with the specified key already exists for the command, it will be updated with the new value
  - If no entry exists, a new metadata entry will be created
  - The operation is idempotent - repeated calls with the same key and value will not create duplicate entries
  - Raises `ValueError` if `command_uuid` is not set on the command effect
##  Implementation Details 
###  Validation 
The effect performs validation at two stages:
  1. **SDK Validation** : Ensures all required fields are provided before the effect is created
     - `command_uuid` must be set on the command effect
     - Both `key` and `value` must be provided
  2. **Server-Side Validation** : When the effect is processed, the server verifies that the referenced command exists
     - Returns a descriptive error if the command is not found after all effects in the list have been processed
##  Example Usage 
###  Basic Usage 
    ```python
    from canvas_sdk.commands import PlanCommand
    plan = PlanCommand(command_uuid="63hdik")
    effect = plan.upsert_metadata(key="my_plugin:priority", value="high")
    ```
###  Example: Chaining with originate() 
You can attach metadata to a command at the same time you originate it by returning both effects in the same list:
    ```python
    import uuid
    from canvas_sdk.commands import PlanCommand
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class OriginateWithMetadata(BaseHandler):
        """Originates a plan command with metadata attached in a single operation."""
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART__SECTION__LOADED)
        def compute(self) -> list[Effect]:
            command_uuid = str(uuid.uuid4())
            plan = PlanCommand(
                note_uuid=self.context["note_id"],
                command_uuid=command_uuid,
                narrative="Follow up in 2 weeks",
            )
            return [
                plan.originate(),
                plan.upsert_metadata(key="my_plugin:source", value="auto_generated"),
            ]
    ```
###  Example: Tagging a command on commit 
    ```python
    from canvas_sdk.commands import PlanCommand
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class TagPlanOnCommit(BaseHandler):
        """Tags a plan command with a workflow stage when it is committed."""
        RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__POST_COMMIT)
        def compute(self) -> list[Effect]:
            plan = PlanCommand(command_uuid=self.event.target.id)
            return [plan.upsert_metadata(key="my_plugin:workflow_stage", value="committed")]
    ```
###  Responding to metadata events 
Once metadata is upserted, `COMMAND_METADATA_CREATED` and `COMMAND_METADATA_UPDATED` events are emitted and can be handled by plugins:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.command import CommandMetadata
    from logger import log
    class CommandMetadataListener(BaseHandler):
        """Reacts to command metadata changes."""
        RESPONDS_TO = [
            EventType.Name(EventType.COMMAND_METADATA_CREATED),
            EventType.Name(EventType.COMMAND_METADATA_UPDATED),
        ]
        def compute(self) -> list[Effect]:
            metadata = CommandMetadata.objects.get(id=self.event.target.id)
            log.info(f"Command {metadata.command.id}: {metadata.key}={metadata.value}")
            return []
    ```
##  Best Practices 
###  Key Naming Conventions 
  1. **Use Descriptive Names** : Choose keys that clearly indicate the purpose of the metadata
     - Good: `workflow_stage`, `external_id`, `review_status`
     - Avoid: `data1`, `temp`, `misc`
  2. **Namespace Your Keys** : Prefix keys with your plugin name to avoid collisions with other plugins
     - Example: `my_plugin:workflow_stage`, `my_plugin:external_id`
###  Value Storage 
**String Serialization** : All values are stored as strings. For complex data types, serialize to JSON:
    ```python
       import json
       from canvas_sdk.commands import DiagnoseCommand
       cmd = DiagnoseCommand(command_uuid="abc123")
       data = {"reviewer": "user-id", "approved_at": "2025-01-15T10:30:00Z"}
       cmd.upsert_metadata(key="my_plugin:review", value=json.dumps(data))
    ```
##  Notes 
  - Metadata entries are command-specific — the same key can have different values for different commands
  - There is no built-in versioning; updating a key overwrites the previous value
  - The system does not enforce any schema on metadata values — validation is the responsibility of the implementing code
  - The `key` field supports up to 256 characters
  - To collect metadata from a user in the chart rather than writing it from a plugin, see the [Command Metadata Create form effect](/sdk/command-metadata-create-form-effect/)

# Command Validation

Source: https://docs.canvasmedical.com/sdk/effect-command-validation/

The `CommandValidationErrorEffect` returns structured error messages that are displayed to users in the Canvas UI. It serves two purposes:
  - **Validate a command** as it is entered in the Canvas UI, surfacing problems before it can be committed (`__POST_VALIDATION` events).
  - **Block a deletion** by returning the effect from a command's `__PRE_DELETE` handler.
In both cases you build a `CommandValidationErrorEffect`, attach one or more error messages, and return it from your handler.
Where these errors are enforced differs by event: `__POST_VALIDATION` errors block a commit **only in the Canvas UI** , while `__PRE_DELETE` errors block a deletion through **both** the Canvas UI and the SDK [commands module](/sdk/commands/). Each section below covers the specifics.
##  The effect 
###  CommandValidationErrorEffect 
The `CommandValidationErrorEffect` class accepts an optional list of `ValidationError` objects during initialization:
Attribute| Type| Required| Description  
---|---|---|---  
`errors`| list[ValidationError]| optional| List of validation errors to be displayed to the user.  
###  ValidationError 
Each `ValidationError` object represents a single validation error message:
Attribute| Type| Required| Description  
---|---|---|---  
`message`| String| required| The validation error message to display. Must not be empty.  
###  Building the errors 
Add errors incrementally with `add_error()`, which returns `self` so calls can be chained:
    ```python
    effect = CommandValidationErrorEffect()
    effect.add_error("Narrative is required").add_error("Please provide details about the plan")
    return [effect.apply()]
    ```
Or pass a list of `ValidationError` objects to the constructor:
    ```python
    from canvas_sdk.commands.validation import CommandValidationErrorEffect, ValidationError
    errors = [
        ValidationError("Narrative is required"),
        ValidationError("Narrative must be at least 10 characters long"),
    ]
    effect = CommandValidationErrorEffect(errors=errors)
    return [effect.apply()]
    ```
##  Validate a command 
Use `CommandValidationErrorEffect` with a command's `__POST_VALIDATION` event to check the command as it is entered and surface problems before it is committed. These events follow the pattern:
`{COMMAND_KEY}_COMMAND__POST_VALIDATION`
The following command types fire `__POST_VALIDATION` and can be validated with this effect:
  - `ADJUST_PRESCRIPTION_COMMAND__POST_VALIDATION`
  - `ALLERGY_COMMAND__POST_VALIDATION`
  - `APPROVE_REFILL_COMMAND__POST_VALIDATION`
  - `ASSESS_CODING_GAP_COMMAND__POST_VALIDATION`
  - `ASSESS_COMMAND__POST_VALIDATION`
  - `CANCEL_PRESCRIPTION_COMMAND__POST_VALIDATION`
  - `CHANGE_MEDICATION_COMMAND__POST_VALIDATION`
  - `CHART_SECTION_REVIEW_COMMAND__POST_VALIDATION`
  - `CLIPBOARD_COMMAND__POST_VALIDATION`
  - `CLOSE_GOAL_COMMAND__POST_VALIDATION`
  - `CREATE_CODING_GAP_COMMAND__POST_VALIDATION`
  - `DEFER_CODING_GAP_COMMAND__POST_VALIDATION`
  - `DENY_REFILL_COMMAND__POST_VALIDATION`
  - `DIAGNOSE_COMMAND__POST_VALIDATION`
  - `EDUCATIONAL_MATERIAL_COMMAND__POST_VALIDATION`
  - `FAMILY_HISTORY_COMMAND__POST_VALIDATION`
  - `FOLLOW_UP_COMMAND__POST_VALIDATION`
  - `GOAL_COMMAND__POST_VALIDATION`
  - `HISTORY_OF_PRESENT_ILLNESS_COMMAND__POST_VALIDATION`
  - `IMAGING_ORDER_COMMAND__POST_VALIDATION`
  - `IMMUNIZATION_STATEMENT_COMMAND__POST_VALIDATION`
  - `IMMUNIZE_COMMAND__POST_VALIDATION`
  - `INSTRUCT_COMMAND__POST_VALIDATION`
  - `LAB_ORDER_COMMAND__POST_VALIDATION`
  - `MEDICAL_HISTORY_COMMAND__POST_VALIDATION`
  - `MEDICATION_STATEMENT_COMMAND__POST_VALIDATION`
  - `PERFORM_COMMAND__POST_VALIDATION`
  - `PHYSICAL_EXAM_COMMAND__POST_VALIDATION`
  - `PLAN_COMMAND__POST_VALIDATION`
  - `POC_LAB_TEST_COMMAND__POST_VALIDATION`
  - `PRESCRIBE_COMMAND__POST_VALIDATION`
  - `QUESTIONNAIRE_COMMAND__POST_VALIDATION`
  - `REASON_FOR_VISIT_COMMAND__POST_VALIDATION`
  - `REFERENCE_COMMAND__POST_VALIDATION`
  - `REFER_COMMAND__POST_VALIDATION`
  - `REFILL_COMMAND__POST_VALIDATION`
  - `REMOVE_ALLERGY_COMMAND__POST_VALIDATION`
  - `RESOLVE_CONDITION_COMMAND__POST_VALIDATION`
  - `ROS_COMMAND__POST_VALIDATION`
  - `SNOOZE_PROTOCOL_COMMAND__POST_VALIDATION`
  - `STOP_MEDICATION_COMMAND__POST_VALIDATION`
  - `STRUCTURED_ASSESSMENT_COMMAND__POST_VALIDATION`
  - `SURGICAL_HISTORY_COMMAND__POST_VALIDATION`
  - `TASK_COMMAND__POST_VALIDATION`
  - `UPDATE_DIAGNOSIS_COMMAND__POST_VALIDATION`
  - `UPDATE_GOAL_COMMAND__POST_VALIDATION`
  - `VALIDATE_CODING_GAP_COMMAND__POST_VALIDATION`
  - `VISUAL_EXAM_FINDING_COMMAND__POST_VALIDATION`
  - `VITALS_COMMAND__POST_VALIDATION`
The Custom Command, Imaging Review, Lab Review, Referral Review, Uncategorized Document Review commands do **not** fire `__POST_VALIDATION`, so they can't be validated with this effect.
The following handler validates a Plan command to ensure it meets specific requirements:
    ```python
    from canvas_sdk.commands import PlanCommand
    from canvas_sdk.commands.validation import CommandValidationErrorEffect
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    class MyHandler(BaseHandler):
        """
        Example protocol demonstrating command validation.
        This protocol validates Plan commands to ensure they meet
        organizational requirements before being committed.
        """
        RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__POST_VALIDATION)
        def compute(self) -> list[Effect]:
            log.info("Running command validation protocol.")
            # Extract command fields from context
            narrative = self.context["fields"]["narrative"]
            # Create the validation effect
            effect = CommandValidationErrorEffect()
            # Perform validation checks
            if not narrative or not narrative.strip():
                effect.add_error("Narrative is required and cannot be empty")
            elif len(narrative.strip()) < 10:
                effect.add_error("Narrative must be at least 10 characters long")
            # Check for prohibited content
            prohibited_terms = ["TODO", "TBD", "FIXME"]
            if any(term in narrative.upper() for term in prohibited_terms):
                effect.add_error("Narrative cannot contain placeholder text (TODO, TBD, FIXME)")
            # Check for required keywords (example: follow-up plans must mention timeline)
            if "follow" in narrative.lower() and not any(word in narrative.lower() for word in ["week", "month", "day"]):
                effect.add_error("Follow-up plans must include a specific timeline")
            # Return the effect
            return [effect.apply()]
    ```
When validation errors are returned, the Canvas UI shows them to the user — the command's action buttons are disabled and the messages appear as a tooltip — so the command can't be committed there. Multiple errors can be returned at once, and all are displayed.
> **Note:** `__POST_VALIDATION` only gates committing **in the Canvas UI**. A `.commit()` made through the SDK [commands module](/sdk/commands/) is **not** blocked by these errors — the command still commits. Use it as a UI guardrail, not as an enforced rule on SDK-driven commits. (Blocking a deletion, below, _does_ work through both the UI and the SDK.)
##  Block a deletion 
Return a `CommandValidationErrorEffect` from a command's `__PRE_DELETE` handler to block its deletion. Unlike `__POST_VALIDATION`, this works through **both** the Canvas UI and the SDK [commands module](/sdk/commands/): the deletion is aborted, the surrounding transaction is rolled back, and the error messages are returned to whatever initiated the delete — a [`delete()`](/sdk/commands/) call or a delete in the UI. For SDK-initiated deletes, the error is written to `canvas logs`. Pre-delete events follow the pattern:
`{COMMAND_KEY}_COMMAND__PRE_DELETE`
`__PRE_DELETE` is fired by the following command types (every command except Chart Section Review):
  - `ADJUST_PRESCRIPTION_COMMAND__PRE_DELETE`
  - `ALLERGY_COMMAND__PRE_DELETE`
  - `APPROVE_REFILL_COMMAND__PRE_DELETE`
  - `ASSESS_CODING_GAP_COMMAND__PRE_DELETE`
  - `ASSESS_COMMAND__PRE_DELETE`
  - `CANCEL_PRESCRIPTION_COMMAND__PRE_DELETE`
  - `CHANGE_MEDICATION_COMMAND__PRE_DELETE`
  - `CLIPBOARD_COMMAND__PRE_DELETE`
  - `CLOSE_GOAL_COMMAND__PRE_DELETE`
  - `CREATE_CODING_GAP_COMMAND__PRE_DELETE`
  - `CUSTOM_COMMAND_COMMAND__PRE_DELETE`
  - `DEFER_CODING_GAP_COMMAND__PRE_DELETE`
  - `DENY_REFILL_COMMAND__PRE_DELETE`
  - `DIAGNOSE_COMMAND__PRE_DELETE`
  - `EDUCATIONAL_MATERIAL_COMMAND__PRE_DELETE`
  - `FAMILY_HISTORY_COMMAND__PRE_DELETE`
  - `FOLLOW_UP_COMMAND__PRE_DELETE`
  - `GOAL_COMMAND__PRE_DELETE`
  - `HISTORY_OF_PRESENT_ILLNESS_COMMAND__PRE_DELETE`
  - `IMAGING_ORDER_COMMAND__PRE_DELETE`
  - `IMAGING_REVIEW_COMMAND__PRE_DELETE`
  - `IMMUNIZATION_STATEMENT_COMMAND__PRE_DELETE`
  - `IMMUNIZE_COMMAND__PRE_DELETE`
  - `INSTRUCT_COMMAND__PRE_DELETE`
  - `LAB_ORDER_COMMAND__PRE_DELETE`
  - `LAB_REVIEW_COMMAND__PRE_DELETE`
  - `MEDICAL_HISTORY_COMMAND__PRE_DELETE`
  - `MEDICATION_STATEMENT_COMMAND__PRE_DELETE`
  - `PERFORM_COMMAND__PRE_DELETE`
  - `PHYSICAL_EXAM_COMMAND__PRE_DELETE`
  - `PLAN_COMMAND__PRE_DELETE`
  - `POC_LAB_TEST_COMMAND__PRE_DELETE`
  - `PRESCRIBE_COMMAND__PRE_DELETE`
  - `QUESTIONNAIRE_COMMAND__PRE_DELETE`
  - `REASON_FOR_VISIT_COMMAND__PRE_DELETE`
  - `REFERENCE_COMMAND__PRE_DELETE`
  - `REFERRAL_REVIEW_COMMAND__PRE_DELETE`
  - `REFER_COMMAND__PRE_DELETE`
  - `REFILL_COMMAND__PRE_DELETE`
  - `REMOVE_ALLERGY_COMMAND__PRE_DELETE`
  - `RESOLVE_CONDITION_COMMAND__PRE_DELETE`
  - `ROS_COMMAND__PRE_DELETE`
  - `SNOOZE_PROTOCOL_COMMAND__PRE_DELETE`
  - `STOP_MEDICATION_COMMAND__PRE_DELETE`
  - `STRUCTURED_ASSESSMENT_COMMAND__PRE_DELETE`
  - `SURGICAL_HISTORY_COMMAND__PRE_DELETE`
  - `TASK_COMMAND__PRE_DELETE`
  - `UNCATEGORIZED_DOCUMENT_REVIEW_COMMAND__PRE_DELETE`
  - `UPDATE_DIAGNOSIS_COMMAND__PRE_DELETE`
  - `UPDATE_GOAL_COMMAND__PRE_DELETE`
  - `VALIDATE_CODING_GAP_COMMAND__PRE_DELETE`
  - `VISUAL_EXAM_FINDING_COMMAND__PRE_DELETE`
  - `VITALS_COMMAND__PRE_DELETE`
The following handler prevents deletion of a Refer command once its priority has been set to `Urgent` or `STAT`, so high-priority referrals can't be removed by mistake. The command's field values are available on the event context, so no extra lookup is needed:
    ```python
    from canvas_sdk.commands import ReferCommand
    from canvas_sdk.commands.validation import CommandValidationErrorEffect
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class BlockUrgentReferralDeletionHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.REFER_COMMAND__PRE_DELETE)
        def compute(self) -> list[Effect]:
            priority = self.context["fields"].get("priority")
            protected = {ReferCommand.Priority.URGENT.value, ReferCommand.Priority.STAT.value}
            if priority in protected:
                effect = CommandValidationErrorEffect()
                effect.add_error(
                    f"A {priority}-priority referral can't be deleted. "
                    "Lower its priority first if you need to remove it."
                )
                return [effect.apply()]
            return []
    ```
When a delete is attempted on an `Urgent` or `STAT` referral, it is blocked and the error message is returned to whoever initiated it.
For more information about command events and their context objects, see the [Events documentation](/sdk/events/).

# Compound Medication Effects

Source: https://docs.canvasmedical.com/sdk/effect-compound-medication/

The Compound Medication effects enable the creation and management of compound medication formulations within the Canvas system. These effects support the customization of medications prepared by compounding pharmacies according to prescriptions.
##  Create Compound Medication 
The `CreateCompoundMedication` effect creates a new compound medication formulation in the system.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`formulation`| `str`| The compound medication formulation (max 105 characters)| Yes  
`potency_unit_code`| `str`| The unit of measurement for the medication| Yes  
`controlled_substance`| `str`| The controlled substance schedule| Yes  
`controlled_substance_ndc`| `str` or `None`| NDC code for controlled substances (dashes removed)| No*  
`active`| `bool`| Whether the compound medication is active| No  
*Required when `controlled_substance` is not "N" (None)
###  Example Usage 
    ```python
    from canvas_sdk.effects.compound_medications import CompoundMedication as CompoundMedicationEffect
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.v1.data.compound_medication import CompoundMedication as CompoundMedicationModel
    class CompoundMedicationCreator(BaseHandler):
      RESPONDS_TO = [EventType.Name(EventType.PATIENT_CREATED)]
      def compute(self):
        # Create a non-controlled compound medication
        compound_med = CompoundMedicationEffect(
          formulation="Testosterone 200mg/mL in Grapeseed Oil",
          potency_unit_code=CompoundMedicationModel.PotencyUnit.Milliliter,
          controlled_substance=CompoundMedicationModel.ControlledSubstanceSchedule.SCHEDULE_NOT_SCHEDULED,
          active=True
        )
        # Create a controlled substance compound medication
        controlled_compound = CompoundMedicationEffect(
          formulation="Hydrocodone 5mg/Acetaminophen 325mg Capsule",
          potency_unit_code=CompoundMedicationModel.PotencyUnit.Capsule,
          controlled_substance=CompoundMedicationModel.ControlledSubstanceSchedule.SCHEDULE_II,
          controlled_substance_ndc="12345678901",
          active=True
        )
        return [compound_med.create(), controlled_compound.create()]
    ```
##  Update Compound Medication 
The `UpdateCompoundMedication` effect modifies an existing compound medication formulation.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`compound_medication_id`| `str`| The ID of the compound medication to update| Yes  
`formulation`| `str` or `None`| The compound medication formulation (max 105 characters)| No  
`potency_unit_code`| `str` or `None`| The unit of measurement for the medication| No  
`controlled_substance`| `str` or `None`| The controlled substance schedule| No  
`controlled_substance_ndc`| `str` or `None`| NDC code for controlled substances (dashes removed)| No  
`active`| `bool` or `None`| Whether the compound medication is active| No  
###  Example Usage 
    ```python
    from canvas_sdk.effects.compound_medications import CompoundMedication as CompoundMedicationEffect
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.compound_medication import CompoundMedication as CompoundMedicationModel
    from canvas_sdk.events import EventType
    class CompoundMedicationUpdater(BaseHandler):
      RESPONDS_TO = [EventType.Name(EventType.PLUGIN_CREATED)]
      def compute(self):
        # Find a compound medication to update
        compound_med = CompoundMedicationModel.objects.filter(
            formulation__contains="Testosterone"
        ).first()
        if compound_med:
            # Update to make it a controlled substance
            update_effect = CompoundMedicationEffect(
                compound_medication_id=str(compound_med.id),
                controlled_substance="III",
                controlled_substance_ndc="98765432101"
            )
            return [update_effect.update()]
        return []
    ```
##  Implementation Details 
  - **Formulation Validation** : The formulation field is limited to 105 characters
  - **NDC Formatting** : Any dashes in the NDC code are automatically removed during processing
  - **Cross-field Validation** : When a controlled substance schedule is specified (anything other than "N"), an NDC code must be provided
  - **Default Values** : If not specified, `active` defaults to `True` for new compound medications
  - **Potency Unit Codes** : Must use valid codes as defined in the [PotencyUnit](/sdk/data-compound-medication/#potencyunit) enumeration
  - **Controlled Substance Schedules** : Must use valid values as defined in the [ControlledSubstanceSchedule](/sdk/data-compound-medication/#controlledsubstanceschedule) enumeration
##  Validation 
Both effects perform validation before execution:
###  Create Effect Validation: 
  - Validates all required fields are provided
  - Ensures `potency_unit_code` is a valid value from the PotencyUnit enumeration
  - Ensures `controlled_substance` is a valid schedule from the ControlledSubstanceSchedule enumeration
  - Validates NDC is provided for controlled substances (when schedule is not "N")
  - Checks formulation length does not exceed 105 characters
###  Update Effect Validation: 
  - Verifies the compound medication exists before updating
  - Validates any provided fields follow the same rules as creation
  - Ensures NDC is provided if updating to a controlled substance
  - Only updates fields that are explicitly provided (partial updates supported)
##  Error Handling 
If validation fails, a `ValidationError` is raised with detailed error messages indicating which fields failed validation and why. Error messages are aggregated to provide comprehensive feedback about all validation failures at once.

# Configure Command Buttons

Source: https://docs.canvasmedical.com/sdk/effect-configure-command-buttons/

The `ConfigureCommandButtons` effect allows plugins to hide or disable the command buttons that appear in specific areas of the patient chart — such as the conditions section, medications section, or protocol cards.
##  Locations 
The `Location` enum defines which areas of the chart can be configured:
Value| Area  
---|---  
`CONDITIONS`| Conditions chart summary section  
`MEDICATIONS`| Medications chart summary section  
`ALLERGIES`| Allergies chart summary section  
`GOALS`| Goals chart summary section  
`VITALS`| Vitals chart summary section  
`IMMUNIZATIONS`| Immunizations chart summary section  
`SURGICAL_HISTORY`| Surgical history chart summary section  
`FAMILY_HISTORY`| Family history chart summary section  
`SOCIAL_DETERMINANTS`| Social determinants chart summary section  
`CARE_TEAMS`| Care teams chart summary section  
`CODING_GAPS`| Coding gaps chart summary section  
`QUALITY_PROTOCOLS`| Quality protocol result cards  
`LAB_REVIEWS`| Lab report review result cards  
`IMAGING_REVIEWS`| Imaging report review result cards  
`REFERRAL_REVIEWS`| Referral report review result cards  
`DOCUMENT_REVIEWS`| Uncategorized document review result cards  
##  Visibility 
Each location can be configured with one of three visibility values:
Value| Behaviour  
---|---  
`VISIBLE`| Buttons are shown and interactive (default when not listed)  
`HIDDEN`| Buttons are not rendered  
`DISABLED`| Buttons are rendered but not interactive  
##  Attributes 
Each entry in `locations` is a `LocationConfig` with the following attributes:
Attribute| Required| Type| Description  
---|---|---|---  
`location`| yes| `Location`| The chart area to configure  
`visibility`| yes| `Visibility`| The visibility state for that area  
Top-level| Required| Type| Description  
---|---|---|---  
`patient_id`| yes| `str`| The patient id  
`locations`| no| `list[LocationConfig]`| Areas to configure. Areas not listed retain their default visible state.  
##  Validation 
Duplicate `location` values in the `locations` list will raise a `ValidationError` when `apply()` is called.
##  Example: Patient Chart Load 
`PATIENT_TIMELINE__GET_CONFIGURATION` fires every time a patient chart is opened, making it a convenient hook for configuring button visibility on chart load. The example below hides all command buttons across every location:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.configure_command_buttons import ConfigureCommandButtons
    from canvas_sdk.events import EventType
    from canvas_sdk.protocols import BaseProtocol
    Location = ConfigureCommandButtons.Location
    LocationConfig = ConfigureCommandButtons.LocationConfig
    Visibility = ConfigureCommandButtons.Visibility
    class HideButtonsOnChartLoad(BaseProtocol):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_TIMELINE__GET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [
                ConfigureCommandButtons(
                    patient_id=self.target,
                    locations=[
                        LocationConfig(location=loc, visibility=Visibility.HIDDEN)
                        for loc in Location
                    ],
                ).apply()
            ]
    ```
##  Example: Note Applications 
One use case is toggling chart buttons alongside a `NoteApplication`. When the application tab opens, `on_open` disables chart buttons. When the provider switches back to the note body, Canvas sends a `NOTE_TAB_CHANGE` message to the iframe, which calls a `SimpleAPI` endpoint to restore them.

                    content=render_to_string(
                        "templates/charting_app.html",
                        context={"identifier": self.IDENTIFIER},
                    ),
                    title="My Charting App",
                ).apply(),
                ConfigureCommandButtons(
                    patient_id=patient_id,
                    locations=[
                        LocationConfig(location=loc, visibility=Visibility.DISABLED)
                        for loc in Location
                    ],
                ).apply(),
            ]
    class CommandButtonsApi(StaffSessionAuthMixin, SimpleAPI):
        @api.post("/configure-buttons/disable")
        def disable(self) -> list[Response | Effect]:
            patient_id = self.request.json().get("patient_id")
            return [
                JSONResponse({"ok": True}),
                ConfigureCommandButtons(
                    patient_id=patient_id,
                    locations=[
                        LocationConfig(location=loc, visibility=Visibility.DISABLED)
                        for loc in Location
                    ],

                    locations=[
                        LocationConfig(location=loc, visibility=Visibility.VISIBLE)
                        for loc in Location
                    ],
                ).apply(),
            ]
    ```
###  Template 
The iframe listens for `NOTE_TAB_CHANGE` messages from Canvas and calls the appropriate endpoint. When `tab` is `"note"` the provider has switched back to the note body; when `tab` matches the application's identifier the application tab is active.
    ```html
    <!-- templates/charting_app.html -->
    <script>
      var port;
      var myIdentifier = '';
      function post(endpoint, patientId) {
        fetch('/plugin-io/api/my_plugin/configure-buttons/' + endpoint, {
          method: 'POST',
          body: JSON.stringify({ patient_id: patientId })
        });
      }
      window.addEventListener('message', function(event) {
        if (event.data?.type === 'INIT_CHANNEL') {
          port = event.ports[0];
          port.onmessage = function(e) {
            if (e.data?.type === 'NOTE_TAB_CHANGE') {
              if (e.data.tab === 'note') post('enable', e.data.patient.id);
              else if (e.data.tab === myIdentifier) post('disable', e.data.patient.id);
            }
          };
        }
      });
    </script>
    ```
Both `MyChartingApp` and `CommandButtonsApi` should be registered as `handlers` in your `CANVAS_MANIFEST.json`.

# CreateCCDA

Source: https://docs.canvasmedical.com/sdk/effect-create-ccda-export/

The `CreateCCDA` effect creates a C-CDA document for a patient with the provided XML content. This effect allows plugins to store C-CDA XML documents, which can be used for clinical document exchange, patient summaries, or referrals.
This effect stores a C-CDA document, generating or otherwise sourcing that document is the responsibility of the plugin.
##  Attributes 
Name| Type| Required| Description  
---|---|---|---  
`patient_id`| `str`| Yes| The patient's key (UUID).  
`content`| `str`| Yes| The C-CDA XML content as a string. Must be valid XML.  
`document_type`| `DocumentType`| No| Type of C-CDA document. Defaults to `DocumentType.CCD`.  
##  DocumentType Enum 
Value| Description  
---|---  
`CCD`| Continuity of Care Document (default)  
`REFERRAL`| Referral document  
##  Validation 
The effect performs the following validations before execution:
  - **Patient Exists** : Verifies that a patient with the given `patient_id` exists in the system.
  - **Valid XML** : Validates that the `content` field contains well-formed XML. Malformed XML will result in a validation error.
  - **Required Fields** : Both `patient_id` and `content` must be non-empty strings.
##  Example Usage 
###  Basic CCD Creation 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.ccda import CreateCCDA, DocumentType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PATIENT_UPDATED)]
        def compute(self) -> list[Effect]:
            # Sample C-CDA XML content
            ccda_xml = """<?xml version="1.0" encoding="UTF-8"?>
            <ClinicalDocument xmlns="urn:hl7-org:v3">
                <typeId root="2.16.840.1.113883.1.3" extension="POCD_HD000040"/>
                <templateId root="2.16.840.1.113883.10.20.22.1.1"/>
                <id root="document-id"/>
                <code code="34133-9" displayName="Summarization of Episode Note"
                      codeSystem="2.16.840.1.113883.6.1"/>
                <title>Patient Summary</title>
                <effectiveTime value="20240101120000"/>
                <confidentialityCode code="N" codeSystem="2.16.840.1.113883.5.25"/>
                <languageCode code="en-US"/>
            </ClinicalDocument>"""
            effect = CreateCCDA(
                patient_id="a1b2c3d4-e5f6-7890-abcd-ef1234567890",
                content=ccda_xml,
                document_type=DocumentType.CCD,
            )
            return [effect.apply()]
    ```
###  Creating a Referral Document 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.ccda import CreateCCDA, DocumentType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PATIENT_UPDATED)]
        def compute(self) -> list[Effect]:
            referral_xml_content = "<ClinicalDocument>...</ClinicalDocument>"
            effect = CreateCCDA(
                patient_id="a1b2c3d4-e5f6-7890-abcd-ef1234567890",
                content=referral_xml_content,
                document_type=DocumentType.REFERRAL,
            )
            return [effect.apply()]
    ```
###  Using Default Document Type 
When `document_type` is not specified, it defaults to `CCD`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.ccda import CreateCCDA
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PATIENT_UPDATED)]
        def compute(self) -> list[Effect]:
            ccda_xml = "<ClinicalDocument>...</ClinicalDocument>"
            effect = CreateCCDA(
                patient_id="a1b2c3d4-e5f6-7890-abcd-ef1234567890",
                content=ccda_xml,
            )
            # document_type defaults to DocumentType.CCD
            return [effect.apply()]
    ```
##  Use Cases 
  - **Clinical Document Exchange** : Generate C-CDAs for sharing patient information with external systems or providers.
  - **Patient Summaries** : Create Continuity of Care Documents containing a patient's clinical summary.
  - **Referral Documentation** : Generate referral documents when referring patients to specialists.
  - **Integration with External Systems** : Produce standardized C-CDA documents for healthcare interoperability.
##  Notes 
  - The C-CDA XML content is stored as a file on the patient's record. You can access the record in Settings > CCDAs to be able to view, transmit, or download the file.

# CreatePatientExternalIdentifier

Source: https://docs.canvasmedical.com/sdk/effect-create-patient-external-identifier/

Creates a new external identifier for a patient.
###  Parameters 
Name| Type| Description  
---|---|---  
patient_id| UUID| The unique identifier of the patient.  
system| String| The system for the external identifier (url).  
value| String| The value of the external identifier.  
###  Example 
    ```python
    from canvas_sdk.effects.patient import CreatePatientExternalIdentifier
    effect = CreatePatientExternalIdentifier(
        patient_id="1eed3ea2a8d546a1b681a2a45de1d790",
        system="https://www.va.gov/",
        value="VET123456"
    )
    effect.create()
    ```
This effect will create a new external identifier for the specified patient.

# CreatePatientPreferredPharmacies

Source: https://docs.canvasmedical.com/sdk/effect-create-patient-preferred-pharmacies/

Creates preferred pharmacies for a patient.
###  Parameters 
Name| Type| Description  
---|---|---  
patient_id| `str` or `UUID`| The unique identifier of the patient.  
pharmacies| `list[PatientPreferredPharmacy]`| List of pharmacies to create.  
###  PatientPreferredPharmacy 
The `PatientPreferredPharmacy` dataclass represents a patient's preferred pharmacy, and if it's their default pharmacy.
###  Validation 
When this effect is interpreted, Canvas validates the `ncpdp_id` before setting the preferred pharmacy. If the `ncpdp_id` is invalid or does not exist, the effect will fail.
To ensure the `ncpdp_id` exists before using this effect, you can verify it using Canvas's [pharmacy HTTP utility](/sdk/utils/#making-requests-to-the-pharmacy-service) to check the pharmacy beforehand.
####  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`ncpdp_id`| `str`| The NCPDC identifier of the pharmacy.| Yes  
`default`| `bool`| Indicates if this is the patient's default pharmacy.| No, defaults to `False`  
###  Example 
    ```python
    from canvas_sdk.effects.patient import CreatePatientPreferredPharmacies, PatientPreferredPharmacy
    from canvas_sdk.v1.data import Patient as PatientModel
    first_patient_id = PatientModel.objects.values_list("id", flat=True).first()
    preferred_pharmacies_effect = CreatePatientPreferredPharmacies(
                                    pharmacies=[PatientPreferredPharmacy(ncpdp_id="0586163", default=True)],
                                    patient_id=first_patient_id
    )
    preferred_pharmacies_effect.create()
    ```
This effect will create a new preferred pharmacy for the specified patient.
Since the `default` attribute is set to `True`, it will mark this pharmacy as the patient's default preferred pharmacy.

# Data Integration

Source: https://docs.canvasmedical.com/sdk/effect-data-integration/

Plugins can automate triage of inbound clinical documents in the [Data Integration queue](/sdk/data-integration-task/) — lab reports, imaging reports, faxes, clinical and administrative documents, and other uploaded files awaiting staff review before they're attached to a patient's chart.
Most of these effects work by writing a **prefill suggestion** to the IntegrationTask. The Data Integration UI surfaces that suggestion as a pre-populated value in the staff member's review form — the suggested patient, document type, template values, or reviewer assignment — along with optional annotation badges. A staff member still reviews and commits the change; the plugin doesn't directly mutate the IntegrationTask.
The exceptions are `JunkDocument` and `RemoveDocumentFromPatient`, which act on the IntegrationTask's status or patient link immediately without writing a prefill.
##  Assigning a Reviewer 
To assign a staff member or team as the reviewer for a document in the Data Integration queue, import the `AssignDocumentReviewer` class from `canvas_sdk.effects.data_integration` and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document.  
`reviewer_id`| optional| string| The `id` of the [Staff](/sdk/data-staff/#staff) member to assign as reviewer.  
`team_id`| optional| string| The `id` of the [Team](/sdk/data-team/#team) to assign as reviewer.  
`review_mode`| optional| ReviewMode| Review mode. Defaults to `ReviewMode.REVIEW_REQUIRED`.  
`annotations`| optional| list| List of annotations for display in the UI. See Annotations.  
Supply either `reviewer_id` or `team_id`, not both. If both are supplied, the staff reviewer is used and the team is ignored when the Data Integration UI pre-populates the reviewer field. Supplying neither makes the effect a no-op.
###  ReviewMode 
Value| Description  
---|---  
`ReviewMode.REVIEW_REQUIRED` (default)| Document requires explicit review.  
`ReviewMode.ALREADY_REVIEWED`| Document is marked as already reviewed.  
`ReviewMode.REVIEW_NOT_REQUIRED`| Document does not require review.  
An example of assigning a staff reviewer. Annotations render as colored badges next to the reviewer field in the Data Integration UI — useful for surfacing why the plugin chose this reviewer:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import AssignDocumentReviewer, ReviewMode
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class AssignReviewerHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_RECEIVED)
        def compute(self) -> list[Effect]:
            return [
                AssignDocumentReviewer(
                    document_id=self.event.target.id,
                    reviewer_id="4150cd20de8a470aa570a852859ac87e",
                    review_mode=ReviewMode.ALREADY_REVIEWED,
                    annotations=[
                        {"text": "Team lead", "color": "#4CAF50"},
                        {"text": "Auto-assigned", "color": "#FF9800"},
                    ],
                ).apply()
            ]
    ```
An example of assigning a team instead of an individual reviewer:
    ```python
    from canvas_sdk.effects.data_integration import AssignDocumentReviewer
    assign_reviewer = AssignDocumentReviewer(
        document_id="d2194110-5c9a-4842-8733-ef09ea5ead11",
        team_id="3f8a2e1c-9b4d-4f5a-8c7e-1d2b3a4c5d6e",
        annotations=[
            {"text": "Routed to Coding team", "color": "#2196F3"},
        ],
    )
    ```
##  Categorizing a Document 
To categorize a document in the Data Integration queue into a specific document type, import the `CategorizeDocument` class from `canvas_sdk.effects.data_integration` and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document to categorize.  
`document_type`| required| DocumentType| Document type information for categorizing the document.  
`annotations`| optional| list| List of annotations for display in the UI. See Annotations.  
###  DocumentType 
The `document_type` parameter is a dictionary with the following fields:
Key|  | Type| Description  
---|---|---|---  
`key`| required| string| The unique key identifying the document type. Must match a key from the Supported Document Types table below.  
`name`| required| string| The human-readable name of the document type. Should match the catalog's `Name` for that key.  
`report_type`| required| string| The type of report. Must be `"CLINICAL"` or `"ADMINISTRATIVE"`.  
`template_type`| required| string | null| Must be `"LabReportTemplate"`, `"ImagingReportTemplate"`, `"SpecialtyReportTemplate"`, or `null`.  
###  Supported Document Types 
Canvas's built-in document type catalog. Use the `Key` value in your `document_type` dict; the other columns show the catalog's `report_type` and the matching parse template (when applicable).

###  Example 
The `DOCUMENT_RECEIVED` event context includes `available_document_types`, a list of every document type the instance supports — each entry carries the `key`, `name`, `report_type`, and `template_type` you'll need to construct a `CategorizeDocument` effect. The idiomatic pattern is to read from that list rather than hardcode catalog values, so a plugin keeps working as the catalog changes.
The handler below matches by `name` (using the Supported Document Types table above as a reference for what names to expect) and forwards the matched values to the effect. `ReportType` and `TemplateType` enum instances are constructed explicitly from the context's string values — the SDK rejects raw strings.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import CategorizeDocument
    from canvas_sdk.effects.data_integration.types import ReportType, TemplateType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class CategorizeLabReports(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_RECEIVED)
        def compute(self) -> list[Effect]:
            available = self.event.context.get("available_document_types", [])
            lab_report = next((dt for dt in available if dt["name"] == "Lab Report"), None)
            if not lab_report:
                return []
            template_type = lab_report.get("template_type")
            return [
                CategorizeDocument(
                    document_id=self.event.target.id,
                    document_type={
                        "key": lab_report["key"],
                        "name": lab_report["name"],
                        "report_type": ReportType(lab_report["report_type"]),
                        "template_type": TemplateType(template_type) if template_type else None,
                    },
                    annotations=[
                        {"text": "AI Categorized", "color": "#4CAF50"},
                    ],
                ).apply()
            ]
    ```
For full end-to-end usage including discovery, error handling, and the other Data Integration effects in a single handler, see the [`data_integration_example` plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/data_integration_example) in canvas-plugins.
##  Linking a Document to a Patient 
To link a document in the Data Integration queue to a patient, import the `LinkDocumentToPatient` class from `canvas_sdk.effects.data_integration` and create an instance of it. The plugin is responsible for matching the patient and supplying their key — the interpreter does not search for matching patients itself.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document.  
`patient_key`| required| string| The `id` of the [Patient](/sdk/data-patient/#patient) to link the document to.  
`annotations`| optional| list| List of annotations for display in the UI. See Annotations.  
An example of linking a document to a patient:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import LinkDocumentToPatient
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.patient import Patient
    class LinkDocumentHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_RECEIVED)
        def compute(self) -> list[Effect]:
            document_id = self.event.target.id
            document_title = self.event.context.get("document", {}).get("title", "")
            # Plugin-specific matching logic — e.g., parse the document title or
            # call an OCR/LLM service to extract patient demographics, then look
            # up the patient via the SDK data module.
            patient = Patient.objects.filter(...).first()
            if not patient:
                return []
            return [
                LinkDocumentToPatient(
                    document_id=document_id,
                    patient_key=patient.id,
                    annotations=[
                        {"text": "AI 92%", "color": "#4CAF50"},
                        {"text": f"Matched from '{document_title}'", "color": "#2196F3"},
                    ],
                ).apply()
            ]
    ```
##  Marking a Document as Junk 
To mark a document in the Data Integration queue as junk (spam), import the `JunkDocument` class and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document to mark as junk.  
`JunkDocument` only works on IntegrationTasks in early-stage states: **Unread** , **Read** , **Error** , **Unread error** , or **Junk** (already). IntegrationTasks in **Processed** or **Reviewed** states cannot be junked — attempting to do so raises a validation error. The effect also validates that `document_id` resolves to an existing IntegrationTask and is a well-formed UUID; missing, malformed, or unknown IDs raise validation errors before the IntegrationTask is touched.
To avoid the validation error for tasks that have moved past the early-stage states, you can read the [`status`](/sdk/data-integration-task/#integrationtask) field from the SDK data module and preflight-check before emitting the effect.
An example that preflight-checks the IntegrationTask status before junking:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import JunkDocument
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.integration_task import IntegrationTask, IntegrationTaskStatus
    class JunkDocumentHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_RECEIVED)
        def compute(self) -> list[Effect]:
            document_id = self.event.target.id
            task = IntegrationTask.objects.get(id=document_id)
            # Skip tasks that have already been processed or reviewed
            if task.status in (IntegrationTaskStatus.PROCESSED, IntegrationTaskStatus.REVIEWED):
                return []
            return [JunkDocument(document_id=document_id).apply()]
    ```
##  Prefilling Document Fields 
`PrefillDocumentFields` pre-populates the parse-template fields on an IntegrationTask. **Only three document types support field prefill** — those whose `template_type` is a known parse-template family:
Document type| `template_type`| SDK data module  
---|---|---  
Lab Report| `LabReportTemplate`| [`LabReportTemplate`](/sdk/data-lab-report-template/)  
Imaging Report| `ImagingReportTemplate`| [`ImagingReportTemplate`](/sdk/data-imaging-report-template/)  
Specialist Consult Report| `SpecialtyReportTemplate`| [`SpecialtyReportTemplate`](/sdk/data-specialty-report-template/)  
Document types with inline fields (Patient Consent, Power of Attorney, the Uncategorized variants, and the other ~30 entries in the Supported Document Types catalog) cannot have their fields prefilled by this effect.
> The wire-level effect type for this class is `UPDATE_DOCUMENT_FIELDS`, which is what appears in event logs and the [effects table](/sdk/effects/#data-integration). The class name is `PrefillDocumentFields`.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document.  
`templates`| required| list[PrefillTemplate]| One or more templates to prefill. Must contain at least one entry.  
`annotations`| optional| list| List of annotations for display in the UI. See Annotations.  
###  PrefillTemplate 
A `PrefillTemplate` is a dictionary with the following keys:
Key|  | Type| Description  
---|---|---|---  
`template_id`| required| int| The integer `dbid` of a `LabReportTemplate`, `ImagingReportTemplate`, or `SpecialtyReportTemplate` record. (Note: this is the integer primary key, not the `id` UUID.) Look this up via the SDK data module — see the example below.  
`template_name`| required| string| The matching template's `.name`.  
`fields`| required| dict[str, PrefillDocumentFieldData]| Map of field name to field data. Keys must match the `label` of a field on the chosen template — iterate `template.fields.all()` to discover the available labels, units, types, and required-ness.  
###  PrefillDocumentFieldData 
A `PrefillDocumentFieldData` is a dictionary with the following keys:
Key|  | Type| Description  
---|---|---|---  
`value`| required| string| The field value, stringified into the form field at render time. The same rules apply to all three template families (`LabReportTemplateField`, `ImagingReportTemplateField`, `SpecialtyReportTemplateField`). Currently supported are fields whose `type` is `"float"`, `"text"`, `"date"`, `"select"`, or `"radio"`. For `"select"` and `"radio"`, the value must exactly match one of the field's `options[*].key` for the dropdown to pre-select.  
`unit`| optional| string| Unit of measurement. Should match the corresponding template field's `units` (`LabReportTemplateField.units`, `ImagingReportTemplateField.units`, or `SpecialtyReportTemplateField.units`).  
`reference_range`| optional| string| Reference range for the value.  
`abnormal`| optional| bool| Whether the value is abnormal.  
`annotations`| optional| list| Per-field annotations. Same shape as Annotations.  
###  Discovering Available Fields 
Before constructing a `PrefillDocumentFields` payload, you can inspect the template to see what labels, units, types, and option keys it defines. The same approach works for `ImagingReportTemplate` and `SpecialtyReportTemplate`.
    ```python
    from canvas_sdk.v1.data import LabReportTemplate
    from logger import log
    def inspect_lab_template(template_name) -> None:
        template = (
            LabReportTemplate.objects
            .active()
            .filter(name=template_name)
            .first()
        )
        if not template:
            log.info(f"No template found with name {template_name}")
            return
        log.info(f"Template: {template.name} (dbid={template.dbid})")
        for field in template.fields.all().order_by("sequence"):
            log.info(
                f"  {field.label}",
                type=field.type,
                units=field.units,
                required=field.required,
                code=field.code,
                code_system=field.code_system,
            )
            for opt in field.options.all():
                log.info(f"    option", key=opt.key, label=opt.label)
    ```
Sample output for a CBC Panel template:
    ```text
    Template: CBC Panel (dbid=42)
      Hemoglobin   type=float  units=g/dL    required=True   code=718-7   code_system=LOINC
      WBC          type=float  units=10^3/uL required=True   code=6690-2  code_system=LOINC
      Differential type=select units=        required=False  code=        code_system=
        option key=NORMAL    label=Normal
        option key=ABNORMAL  label=Abnormal
    ```
With that you can see which labels go into the `fields` dict's keys, what `unit` value to send, and — for `select`/`radio` fields — which `option.key` values are valid for the `value` field.
###  Example 
An example of prefilling a Lab Report. The plugin looks up the CBC Panel template via the [`LabReportTemplate`](/sdk/data-lab-report-template/) SDK data module, then iterates the template's `fields` relation to discover which labels and units are available before filling in the values it extracted from the document.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import PrefillDocumentFields
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import LabReportTemplate
    class PrefillLabReportHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_RECEIVED)
        def compute(self) -> list[Effect]:
            cbc = (
                LabReportTemplate.objects
                .active()
                .filter(name__icontains="CBC")
                .first()
            )
            if not cbc:
                return []
            # Values the plugin extracted from the document via OCR/LLM.
            # Hardcoded here for clarity.
            extracted = {
                "Hemoglobin": ("13.5", False),
                "WBC": ("11.2", True),
            }
            # Iterate the template's fields to discover which labels and units
            # the template defines, then fill in only the ones the plugin has
            # values for. Each field exposes `label`, `units`, `type`, and
            # `required` (see LabReportTemplateField).
            prefill_fields: dict[str, dict] = {}
            for field in cbc.fields.all():
                if field.label not in extracted:
                    continue
                value, abnormal = extracted[field.label]
                prefill_fields[field.label] = {
                    "value": value,
                    "unit": field.units or "",
                    "abnormal": abnormal,
                }
            return [
                PrefillDocumentFields(
                    document_id=self.event.target.id,
                    templates=[
                        {
                            "template_id": cbc.dbid,
                            "template_name": cbc.name,
                            "fields": prefill_fields,
                        },
                    ],
                    annotations=[
                        {"text": "Prefilled via AI", "color": "#FF9800"},
                    ],
                ).apply()
            ]
    ```
##  Removing a Document from a Patient 
To unlink a document from its currently-linked patient in the Data Integration queue, import the `RemoveDocumentFromPatient` class and create an instance of it. An IntegrationTask carries at most one patient link at a time, so this effect simply clears that link.
Attribute|  | Type| Description  
---|---|---|---  
`document_id`| required| string| The `id` of the [IntegrationTask](/sdk/data-integration-task/#integrationtask) document to unlink from its patient.  
An example of unlinking a document from its patient:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.data_integration import RemoveDocumentFromPatient
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class RemoveDocumentHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.DOCUMENT_LINKED_TO_PATIENT)
        def compute(self) -> list[Effect]:
            return [
                RemoveDocumentFromPatient(
                    document_id=self.event.target.id,
                ).apply()
            ]
    ```
##  Annotations 
The `annotations` field on any data integration effect accepts a list of dictionaries with the following keys:
Key| Type| Description  
---|---|---  
`text`| string| The annotation text to display (e.g., "AI 95%").  
`color`| string| Hex color code (e.g., "#4CAF50" for green).  

---

# EventValidationError Effect

Source: https://docs.canvasmedical.com/sdk/effect-event-validation-error/

##  Overview 
The `EventValidationError` effect is used to block the creation of an event (such as a NoteStateChangeEvent create) when custom validation fails. If this effect is returned by a protocol in response to an event (e.g., `NOTE_STATE_CHANGE_EVENT_PRE_CREATE`), the event is aborted and the provided error message is surfaced to the user.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
errors| list[ValidationError]| List of validation errors to display to the user.| Yes  
###  ValidationError dataclass 
Each item in the `errors` list is a `ValidationError` dataclass with the following fields:
Field| Type| Description  
---|---|---  
message| string| The error message to display to the user.  
##  Example Usage 
Return an `EventValidationError` from your protocol's `compute` method to block the event and show a message to the user. You can also return other effects alongside `EventValidationError`.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Note
    from canvas_sdk.v1.data.coverage import CoverageStack
    from canvas_sdk.effects.validation import EventValidationError, ValidationError
    from canvas_sdk.effects.banner_alert import AddBannerAlert, RemoveBannerAlert
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_PRE_CREATE)
        def handle_no_coverage(self, patient_id: str, note: Note) -> list[Effect]:
            """If the patient has no coverage, add banner alert and do not allow notes to be locked or charges pushed."""
            if note.patient.coverages.filter(stack=CoverageStack.IN_USE).count() == 0:
                return [
                    EventValidationError(
                        errors=[
                            ValidationError(
                                message="Patient has no coverage. Do not send claim to billing department until coverage(s) have been added."
                            )
                        ]
                    ).apply(),
                    AddBannerAlert(
                        patient_id=patient_id,
                        key="no_coverage",
                        narrative="Patient has no documented coverages.",
                        placement=[
                            AddBannerAlert.Placement.CHART,
                            AddBannerAlert.Placement.APPOINTMENT_CARD,
                        ],
                        intent=AddBannerAlert.Intent.ALERT,
                    ).apply(),
                ]
            return [RemoveBannerAlert(patient_id=patient_id, key="no_coverage").apply()]
        def handle_no_billing_line_items(self, note: Note) -> Effect | None:
            """If the note has no billing line items, do not allow notes to be locked or charges pushed."""
            if note.billing_line_items.filter(status="active").count() > 0:
                return None
            val_effect = EventValidationError()
            val_effect.add_error(
                "Cannot lock or push charges for a note with no billing line items."
            )
            return val_effect.apply()
        def compute(self) -> list[Effect]:
            state = self.event.context["state"]
            if state not in ["PSH", "LKD"]:
                return []
            note = Note.objects.get(id=self.event.context["note_id"])
            patient_id = str(note.patient.id)
            effects = self.handle_no_coverage(patient_id=patient_id, note=note)
            if v := self.handle_no_billing_line_items(note=note):
                effects.append(v)
            return effects
    ```
##  Supported Events 
Event| Behavior  
---|---  
[`NOTE_STATE_CHANGE_EVENT_PRE_CREATE`](/sdk/events/#notes)| Blocks the note state change (e.g. lock, push charges) and displays errors in the UI.  
[`APPOINTMENT__FORM__UPDATED`](/sdk/events/#appointments)| Disables the Book button on the appointment scheduling modal and displays errors as a tooltip.  
##  Implementation Details 
  - If an `EventValidationError` is returned, the event is aborted and the error message is shown in the UI (if initiated from the UI).
  - This effect is typically used for pre-create validation of events, such as note state changes or appointment scheduling.
  - Any other effects returned alongside an `EventValidationError` are still applied, even though the event itself is blocked. In the example above, the `AddBannerAlert` effect is added and persists even when the note state change is rejected.

# External Event Effect

Source: https://docs.canvasmedical.com/sdk/effect-external-event/

The `ExternalEvent` effect provides a way to create and update external clinical events within the Canvas platform. External events represent clinical encounters from external data sources such as ADT (Admission, Discharge, Transfer) feeds, enabling tracking of patient visits that occur outside of Canvas.
##  Attributes 
Name| Type| Description  
---|---|---  
`external_event_id`| `str` or `UUID` or `None`| Unique identifier of an existing external event. Must be unset when creating; required when updating.  
`patient_id`| `str` or `None`| ID of the patient for this event. Required when creating.  
`visit_identifier`| `str` or `None`| Identifier for the visit/encounter. Required when creating.  
`message_control_id`| `str` or `None`| Unique identifier for the message (e.g., HL7 message control ID). Required when creating.  
`event_type`| `str` or `None`| Type of event (e.g., "ADT^A01" for admission). Required when creating.  
`event_datetime`| `datetime` or `None`| Date and time when the event occurred.  
`event_cancelation_datetime`| `datetime` or `None`| Date and time when the event was cancelled. Set this to mark an event as cancelled.  
`message_datetime`| `datetime` or `None`| Date and time when the message was sent.  
`information_source`| `str` or `None`| Source of the event information (e.g., hospital name, system name).  
`facility_name`| `str` or `None`| Name of the facility where the event occurred.  
`raw_message`| `str` or `None`| Raw message content (e.g., original HL7 message).  
##  Validation & Errors

  - **event_type** is **required**
###  Update Validation 
  - **external_event_id** is **required** and must reference an existing external event
  - All other fields are optional; only dirty (modified) fields are updated
##  Effect Methods 
###  `create()`

# HTTP Request

Source: https://docs.canvasmedical.com/sdk/effect-http-request/

The `HttpRequestEffect` lets a plugin ask the Canvas platform to issue an HTTP request on its behalf. The plugin returns the effect from a handler and the platform performs the call.
We recommend running the request asynchronously by chaining `.set_async(...)` onto the applied effect. The request is then handed off to the platform's async runner, which manages delay, retries, and backoff so the handler doesn't block on the network. Setting `retry_on_status_codes` automatically opts into async execution (equivalent to `.set_async(delay_seconds=0)`), so you only need to call `.set_async(...)` explicitly to add a delay or set `max_retries`.
Without `.set_async(...)` and without `retry_on_status_codes`, the effect is executed inline.
##  Attributes 
Name| Type| Required| Description  
---|---|---|---  
`url`| `str`| Yes| The URL to request. Must be non-empty. Cannot resolve to a private or loopback address (see Security).  
`method`| `HttpMethod`| No| The HTTP method to use. Defaults to `HttpMethod.GET`.  
`headers`| `dict[str, str]` or `None`| No| Request headers. Header values are transmitted as-is — store credentials in the plugin's [`secrets`](/sdk/secrets/) and reference them here rather than hard-coding them.  
`body`| `str` or `None`| No| The request body, as a string. For JSON payloads, serialize with `json.dumps(...)` and set the appropriate `Content-Type` header.  
`retry_on_status_codes`| `list[int]` or `None`| No| HTTP status codes that should trigger a retry. Each value must be in the range `100`–`599`. Setting this automatically routes the request through the async runner (equivalent to `.set_async(delay_seconds=0)`); use `.set_async(...)` only to override the delay or set `max_retries`.  
##  `HttpMethod`
A `StrEnum` of the supported HTTP methods. You can also pass the string value as well.
Member| Value  
---|---  
`HttpMethod.GET`| `"GET"`  
`HttpMethod.POST`| `"POST"`  
`HttpMethod.PUT`| `"PUT"`  
`HttpMethod.PATCH`| `"PATCH"`  
`HttpMethod.DELETE`| `"DELETE"`  
##  Security & Network Behavior 
The platform applies several safeguards before executing the request:
  - **SSRF protection.** The host is resolved and rejected if it points at a private (RFC 1918), loopback, link-local (including the `169.254.169.254` cloud metadata address), multicast, reserved, or unspecified address. Both literal IPs (e.g. `http://10.0.0.1/`) and hostnames that resolve to such addresses are blocked.
  - **Redirect behavior.** GET requests follow redirects normally. Non-GET methods (POST, PUT, PATCH, DELETE) are made with `allow_redirects=False`, so a `3xx` response is returned as-is rather than re-posting data to a different host.
  - **Request timeout.** Each request has a 30-second timeout. Requests that exceed it are aborted.
  - **Connection errors are swallowed.** If the upstream service is unreachable or the request fails at the transport layer, the failure is logged and the effect pipeline continues — it does not raise back into your handler.
  - **Redacted logging.** The platform logs the request method, host, path, and final status code. Query strings, fragments, request headers, request bodies, and response bodies are never logged, so credentials passed via query string or `Authorization` headers do not leak into platform logs.
##  Async Execution 
Chain `.set_async(...)` onto the result of `.apply()` to have the platform schedule the request through its async runner instead of running it inline with the handler. You can read more about async effect execution [here](/sdk/effects/#async-execution).
When `retry_on_status_codes` is set on the effect, the SDK automatically sets `delay_seconds=0` (async-now) so the request is routed through the async runner — you don't need to call `.set_async()` separately just for retries. The async runner uses `retry_on_status_codes` (in combination with `max_retries`) to decide whether a response should trigger a retry.
##  Handling Credentials 
Header values are transmitted to the upstream service exactly as provided. Do not hard-code API tokens or other credentials into your plugin source. Instead, declare them as [secrets](/sdk/secrets/) in `CANVAS_MANIFEST.json` and read them at runtime via `self.secrets` on the handler.
##  Example Usage 
###  Send a POST request asynchronously 
    ```python
    import json
    from canvas_sdk.events import EventType
    from canvas_sdk.effects.http_request import HttpMethod, HttpRequestEffect
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CREATED)
        def compute(self):
            http_effect = HttpRequestEffect(
                url="https://api.example.com/submit",
                method=HttpMethod.POST,
                headers={
                    "Authorization": f"Bearer {self.secrets['MY_API_TOKEN']}",
                    "Content-Type": "application/json",
                },
                body=json.dumps({"patient_id": self.target}),
                retry_on_status_codes=[500, 502, 503],
            )
            # retry_on_status_codes already implies async-now; .set_async() is here to add max_retries
            return [http_effect.apply().set_async(max_retries=3)]
    ```
###  Issue a simple GET request 
    ```python
    http_effect = HttpRequestEffect(
        url="https://api.example.com/status",
    )
    return [http_effect.apply().set_async(delay_seconds=0)]
    ```
###  Schedule a delayed request 
    ```python
    # Run the request 60 seconds from now
    http_effect = HttpRequestEffect(
        url="https://api.example.com/sync",
        method=HttpMethod.PUT,
        body=json.dumps({"status": "ready"}),
        headers={"Content-Type": "application/json"},
    )
    return [http_effect.apply().set_async(delay_seconds=60)]
    ```
##  Validation 
Construction is validated by Pydantic and will raise a `ValidationError` for:
  - An empty `url`.
  - A `method` that is not a member of `HttpMethod`.
  - A `retry_on_status_codes` entry that is not an integer or falls outside the `100`–`599` range.

# Lab Report Effect

Source: https://docs.canvasmedical.com/sdk/effect-lab-report/

The `LabReport` effect lets plugins manage a lab report's full lifecycle, independently of any lab order. It is designed for workflows where a report exists before its structured results do — for example, a scanned report that arrives by fax or upload and is OCR'd asynchronously, so the lab tests and values aren't ready until hours or days after the report is created.
With these effects a plugin can:
  - **Create** a report up front, with no order, no PDF, and no results.
  - **Attach results** (lab tests and values) to that report later, as they become available.
  - **Update** report metadata, such as its name.
  - **Enter-in-error** a report so a user can self-correct a mistake.
A created report is linked to the patient you supply. It starts **empty** — until you attach results it holds no tests or values, and it stays an **uncommitted draft**. A results-less draft does **not** appear in the patient's lab reports in the chart (that view only shows committed reports); it exists but isn't surfaced there yet. The first `attach_results()` commits the report — that's when it fills in, creates the observations behind its values, and appears in the chart, reading like any other lab report. It is **not** a Data Integration document, so it never appears in the Data Integration queue, and Canvas creates the report's diagnostic report and renders a document from its data automatically.
##  Identifying a report 
Every effect references a report by one of two handles:
Handle| What it is| When to use it  
---|---|---  
`reference_id`| A stable identifier your plugin assigns when it creates a report.| The report your plugin created. Required on `create()`.  
`report_id`| The [LabReport](/sdk/data-labs/)'s `id`.| Any report — including ones your plugin didn't create.  
Effects are fire-and-forget, so `create()` does not return the new report's `report_id`. Use the `reference_id` you assigned as your handle for the later `attach`/`update`/`enter_in_error` calls. If you need the `report_id` (for example to act on a report your plugin did not create), read it from the `LAB_REPORT_CREATED` event or query the [LabReport](/sdk/data-labs/) data model by `reference_id` (the handle you assigned is stored there; the data model's own `external_id` is reserved for electronic/Health-Gorilla feed ids).
Namespace your `reference_id` values (e.g. `"my-plugin:batch-2026-06-17:img-44"`) so they don't collide with report ids from other inbound-lab sources.
##  Attributes 
Name| Type| Description  
---|---|---  
`reference_id`| `str` or `None`| The plugin-assigned handle (maximum 40 characters). **Required** when creating; usable as the handle for other operations.  
`report_id`| `UUID` or `None`| The [LabReport](/sdk/data-labs/)'s `id` (a valid uuid string is also accepted). Must be **unset** when creating; an alternative handle otherwise.  
`patient_id`| `str` or `None`| The [Patient](/sdk/data-patient/)'s `id`. **Required** when creating.  
`report_name`| `str` or `None`| Human-readable report name (maps to the report's document name).  
`date_performed`| `datetime` or `None`| The report's effective/displayed date. If omitted on `create`, it defaults to the creation time — correct it later via `update`.  
##  Methods 
###  create() 
Create a lab report decoupled from its results — no order, no PDF, and no values required.
####  Validation 
  - `reference_id` is **required** (it is your handle for attaching results later).
  - `patient_id` is **required**.
  - `report_id` must **not** be set (creation assigns the id).
  - The `reference_id` must not already be in use by an existing report.
####  Example 
    ```python
    import datetime
    from canvas_sdk.effects.lab_report import LabReport
    from canvas_sdk.v1.data.patient import Patient
    patient = Patient.objects.first()
    report = LabReport(
        reference_id="my-plugin:batch-2026-06-17:img-44",
        patient_id=patient.id,
        report_name="CBC (scanned 2026-06-17)",
        date_performed=datetime.datetime.now(),
    )
    effect = report.create()
    ```
###  update() 
Update report metadata, such as renaming it via `report_name`. Only the fields you set are sent. Only `report_name` and `date_performed` can be changed — `update()` **cannot move the report to a different patient** ; the patient is fixed when the report is created. If a report was attached to the wrong patient, enter it in error and recreate it on the correct patient.
####  Validation 
  - Exactly one handle (`reference_id` or `report_id`) is **required**.
  - At least one mutable field (`report_name` or `date_performed`) must be provided.
  - The report must not already be entered-in-error or reviewed by a provider.
####  Example 
    ```python
    from canvas_sdk.effects.lab_report import LabReport
    renamed = LabReport(
        reference_id="my-plugin:batch-2026-06-17:img-44",
        report_name="Complete Blood Count",
    )
    effect = renamed.update()
    ```
###  enter_in_error() 
Flag a report as entered-in-error — use it when a report was filed incorrectly. It junks the report (removing it from active views) and records who entered it in error. The report's observations and its linked DiagnosticReport and DocumentReference records are marked entered-in-error as well. Once a report is entered-in-error (or junked) it can no longer be modified — `update()` and `attach_results()` on it raise a validation error.
####  Validation 
  - A handle (`reference_id` or `report_id`) is **required**.
  - Any other field is ignored (not rejected).
  - The report must not already be entered-in-error or reviewed by a provider.
####  Example 
    ```python
    from canvas_sdk.effects.lab_report import LabReport
    voided = LabReport(reference_id="my-plugin:batch-2026-06-17:img-44")
    effect = voided.enter_in_error()
    ```
##  Attaching results 
Once results are available, attach them with the `attach_results` method on `LabReport`. The report handle comes from the `LabReport` instance (`report_id` or `reference_id`); the method takes a list of `LabTest`s, each grouping the `LabValue`s measured for it — so the values for one test are bundled under that test in the chart. Attaching is **additive** : it appends tests and values without removing any already on the report, and Canvas creates an observation for each value automatically.
Attaching results saves the report and regenerates its linked DiagnosticReport and rendered DocumentReference (the report's document) to reflect the newly attached values. The first `attach_results()` call also commits the report (a never-populated report stays an uncommitted draft). A committed report enters the lab-review workflow **review-required** and **requiring a signature** , but with **no reviewer assigned** — a clinician still has to pick it up, review, and sign it. Once a provider has reviewed it, the report is locked to further SDK edits.
###  Arguments 
Name| Type| Description  
---|---|---  
`lab_tests`| list[`LabTest`]| The tests to attach. At least one is required. The report handle comes from the `LabReport` instance.  
###  `LabTest`
A `LabTest` is a test that was performed — an ordered panel or a single analyte — and it groups its result values (a result test can carry many values). `ontology_test_code`/`ontology_test_name` are the lab's **order/compendium** code and name — _not_ LOINC. LOINC is supplied separately via `codings` (see `CodingData` below).
Name| Type| Description  
---|---|---  
`ontology_test_code`| `str`| The lab's order/compendium code for the test. Defaults to empty string.  
`ontology_test_name`| `str`| Human-readable test name. Defaults to empty string.  
`codings`| list[`CodingData`] or `None`| The test's LOINC coding(s); only LOINC-system codings are stored.  
`values`| list[`LabValue`]| The result values for this test. **At least one is required.**  
###  `LabValue`
Each `LabValue` is one measured result on its test.
Name| Type| Description  
---|---|---  
`value`| `str`| The result value. Required.  
`units`| `str`| Unit of measure (e.g. `"g/dL"`). Defaults to empty string.  
`reference_range`| `str`| Reference range as free text. Defaults to empty string.  
`abnormal_flag`| `AbnormalFlag` or `None`| Flags the value against its reference range. Any non-empty flag marks the result abnormal in the lab report. Defaults to `None`.  
`observation_status`| `ObservationStatus`| Status of the observation. Defaults to `ObservationStatus.FINAL`.  
`comment`| `str`| Free-text comment. Defaults to empty string.  
`codings`| list[`CodingData`] or `None`| The value's LOINC coding(s); only LOINC-system codings are stored.  
###  `CodingData`
A coding attached to a test or a value, reused from the [`Observation`](/sdk/effect-observation/) effect. Only codings whose `system` is `http://loinc.org` are persisted, and the `display` becomes the stored coding name.
Name| Type| Description  
---|---|---  
`code`| `str`| The LOINC code (e.g. `"718-7"`). Required.  
`display`| `str`| Human-readable display; stored as the coding's name.  
`system`| `str`| Coding system URI. Use `"http://loinc.org"`.  
`version`| `str`| Optional coding-system version. Defaults to empty.  
`user_selected`| `bool`| Whether a user selected this coding. Defaults to `False`.  
###  `AbnormalFlag`
A `StrEnum` of abnormal-result flags (HL7 v2 table 0078) for a `LabValue`. Setting any of these marks the result abnormal on the lab report.
Member| Value  
---|---  
`HIGH`| `H`  
`LOW`| `L`  
`CRITICAL_HIGH`| `HH`  
`CRITICAL_LOW`| `LL`  
`BELOW_ABSOLUTE_LOW`| `<`  
`ABOVE_ABSOLUTE_HIGH`| `>`  
`ABNORMAL`| `A`  
`CRITICAL_ABNORMAL`| `AA`  
`SUSCEPTIBLE`| `S`  
`RESISTANT`| `R`  
`INTERMEDIATE`| `I`  
`NEGATIVE`| `NEG`  
`POSITIVE`| `POS`  
###  `ObservationStatus`
A `StrEnum` of statuses for a `LabValue`'s observation. Defaults to `FINAL`.
Member| Value  
---|---  
`FINAL`| `final`  
`PRELIMINARY`| `preliminary`  
`AMENDED`| `amended`  
`CORRECTED`| `corrected`  
`CANCELLED`| `cancelled`  
`REGISTERED`| `registered`  
`ENTERED_IN_ERROR`| `entered-in-error`  
`UNKNOWN`| `unknown`  
####  Validation 
  - Exactly one of `reference_id` or `report_id` is **required**.
  - At least one `LabTest` is **required** , and each `LabTest` requires at least one `LabValue`.
  - The report must exist and must not be entered-in-error or reviewed by a provider.
####  Example 
A SimpleAPI route an OCR service calls once it has abstracted the values:
    ```python
    from canvas_sdk.effects.lab_report import LabReport, LabTest, LabValue
    from canvas_sdk.effects.observation import CodingData
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyAuthMixin, SimpleAPIRoute
    LOINC = "http://loinc.org"
    class LabResultsAPI(APIKeyAuthMixin, SimpleAPIRoute):
        PATH = "/lab-results"
        def post(self) -> list[Response]:
            body = self.request.json()
            return [
                LabReport(reference_id=body["reference_id"]).attach_results(
                    [
                        LabTest(
                            ontology_test_code=test.get("order_code", ""),
                            ontology_test_name=test.get("name", ""),
                            codings=(
                                [CodingData(code=test["loinc"], display=test.get("name", ""), system=LOINC)]
                                if test.get("loinc")
                                else None
                            ),
                            values=[
                                LabValue(
                                    value=value["value"],
                                    units=value.get("units", ""),
                                    reference_range=value.get("reference_range", ""),
                                    codings=(
                                        [CodingData(code=value["loinc"], display=value.get("name", ""), system=LOINC)]
                                        if value.get("loinc")
                                        else None
                                    ),
                                )
                                for value in test["values"]
                            ],
                        )
                        for test in body["tests"]
                    ]
                ),
                JSONResponse({"reference_id": body["reference_id"]}, status_code=202),
            ]
    ```
##  Example Workflow 
The four effects compose into the asynchronous OCR workflow:
  1. A scanned report arrives. The plugin calls `LabReport(reference_id=..., patient_id=..., ...).create()`, keying off an `reference_id` it controls.
  2. Days later, the OCR service finishes. The plugin calls `LabReport(reference_id=...).attach_results([LabTest(..., values=[LabValue(...)])])` to attach the abstracted tests and values — the report's observations populate from there.
  3. To fix the report name, the plugin calls `LabReport(reference_id=..., report_name=...).update()`.
  4. If the report was filed in error, the plugin calls `LabReport(reference_id=...).enter_in_error()`.

# Message Effect

Source: https://docs.canvasmedical.com/sdk/effect-messages/

The `Message` effect provides a unified way to create, edit, and transmit messages between users (patients or staff) within the Canvas platform. It supports standalone creation, immediate send after creating, edits, and dedicated send operations.
##  Attributes 
Name| Type| Description  
---|---|---  
`message_id`| `str` or `UUID` or `None`| Unique identifier of an existing message. Must be unset when creating a new message; required when editing.  
`content`| `str` or `None`| The text body of the message. Required when creating; cannot be empty.  
`sender_id`| `str` or `UUID`| ID of the user (Patient or Staff) who is sending the message.  
`recipient_id`| `str` or `UUID`| ID of the user (Patient or Staff) who will receive the message.  
`read`| `datetime` or `None`| Timestamp indicating when the message was read by the recipient. Defaults to `None` (unread).  
##  Validation & Errors 
Before any effect is emitted, the model runs these checks:
  - **Sender and Recipient Exist** Verifies that both `sender_id` and `recipient_id` belong to either a `Patient` or a `Staff` record.
  - **Create vs. Edit Constraints**
    - **Create** and **Create-and-Send** must **not** include `message_id`.
    - **Create** and **Create-and-Send** must include non-empty `content` (content cannot be blank or whitespace-only).
    - **Edit** operations **must** include a valid `message_id` that already exists in the database.
##  Caveats 
  - **Role Constraints:** Sender and Recipient must always be one of Patient or Staff. Patient-to-Patient messaging is not allowed.
  - **UI Refresh Required:** Due to system constraints, editing a message requires a manual UI refresh for updated content to display.
  - **No Attachments Supported:** The Message effect does not yet support attachments.
  - **Immediate Post for Patient-to-Staff:** Messages created from a Patient to Staff cannot be drafted and will immediately appear in the timeline. This means that `CREATE_AND_SEND` and `SEND` effects will fail in these scenarios. You should only use the `CREATE` method for Patient-to-Staff messaging.
##  Effect Methods 
###  `create()`
Originate a new message record without sending.
  - **Effect Type:** `CREATE_MESSAGE`
  - **Payload:** `{ "data": { content, sender_id, recipient_id } }`
###  `create_and_send()`
Create the message and immediately send it in one operation.
  - **Effect Type:** `CREATE_AND_SEND_MESSAGE`
  - **Payload:** `{ "data": { content, sender_id, recipient_id } }`
###  `edit()`
Modify an existing message's content.
  - **Effect Type:** `EDIT_MESSAGE`
  - **Payload:** `{ "data": { message_id, content?, sender_id?, recipient_id? } }`
  - Only fields marked dirty (modified on the model) are included; unchanged fields remain intact in the system.
###  `send()`
Send an already-created message. Useful if you separated creation from transmission.
  - **Effect Type:** `SEND_MESSAGE`
  - **Payload:** `{ "data": { message_id } }`
##  Example Usage 
    ```python
    from canvas_sdk.v1.data.message import Message as MessageModel
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.v1.data.staff import Staff
    from canvas_sdk.effects.note.message import Message
    staff = Staff.objects.first()
    patient = Patient.objects.first()
    ```
###  Create (originate) only 
    ```python
    m1 = Message(
        content="Your lab results are available.",
        sender_id=staff.id,
        recipient_id=patient.id
    )
    effect_create = m1.create()
    ```
###  Create and send in one step 
    ```python
    m2 = Message(
        content="Your appointment is confirmed.",
        sender_id=staff.id,
        recipient_id=patient.id
    )
    effect_create_and_send = m2.create_and_send()
    m = MessageModel.objects.get(message_id="msg-1234")
    ```
###  Edit an existing message 
    ```python
    m3 = Message(
        message_id=m.id,
        content="Updated: Your appointment has moved to 3pm."
    )
    effect_edit = m3.edit()
    ```
###  Send an existing message 
    ```python
    m4 = Message(message_id=m.id)
    effect_send = m4.send()
    ```

# Note Footer Configuration Effect

Source: https://docs.canvasmedical.com/sdk/effect-note-footer-configuration/

The `NoteFooterConfiguration` effect configures the note footer at the note level (rather than per button). Its primary use is hiding Canvas's default state-transition buttons — Lock, Sign, Push charges, Delete, and so on — so that a plugin can supply its own footer buttons in their place, such as with [Note State Action Buttons](/sdk/handlers-action-buttons/#note-state-action-buttons).
Return this effect in response to the `NOTE_FOOTER__GET_CONFIGURATION` event, which fires when a note's footer is loaded. If your handler does not return a configuration, the default state-transition buttons remain visible.
* * *
##  How it works 
As a note's footer loads, Canvas fires `NOTE_FOOTER__GET_CONFIGURATION` targeting that note's external id. A handler subscribed to the event returns a `NoteFooterConfiguration` effect to configure the footer. If no plugin returns one, the footer keeps its default configuration.
###  Event payload 
Property| Value| Description  
---|---|---  
`event.target.id`| `str` (UUID)| The external id of the [Note](/sdk/data-note/#note) whose footer is loading.  
`event.actor`| user| The logged-in user viewing the note, when available.  
`event.context`| `{}`| Empty — no additional context is provided.  
###  Attributes 
Field| Type| Default| Description  
---|---|---|---  
`hide_default_state_buttons`| `bool`| `False`| Hide Canvas's native footer state-transition buttons for this note.  
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note_footer_configuration import NoteFooterConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class HideDefaultStateButtons(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_FOOTER__GET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [NoteFooterConfiguration(hide_default_state_buttons=True).apply()]
    ```

# NoteMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-note-metadata/

The `Note.upsert_metadata` method provides a flexible key-value storage system for note-specific data within the Canvas system. This method enables the creation and updating of custom metadata entries associated with note records, allowing for extensible note information storage beyond standard note fields.
##  Overview 
Note metadata serves as a powerful extension mechanism for storing custom note-related information that doesn't fit within the standard note data model. Metadata is managed through the `upsert_metadata` method on the `Note` effect class.
##  Method 
###  upsert_metadata(key: str, value: str) → Effect 
Creates or updates a metadata entry for the specified note.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`key`| `str`| Unique identifier for the metadata entry within the note context| Yes  
`value`| `str`| The metadata value to store| Yes  
####  Prerequisites 
The `Note` effect must be initialized with an `instance_id` corresponding to an existing note.
Attribute| Type| Description| Required  
---|---|---|---  
`instance_id`| `UUID` or `str`| Id of the note record to associate metadata with| Yes  
####  Returns 
An `Effect` object configured for upserting note metadata.
####  Behavior 
  - If a metadata entry with the specified key already exists for the note, it will be updated with the new value
  - If no entry exists, a new metadata entry will be created
  - The operation is idempotent - repeated calls with the same key and value will not create duplicate entries
  - Raises `ValueError` if `instance_id` is not set on the `Note` effect
##  Implementation Details 
###  Validation 
The effect performs comprehensive validation before execution:
  1. **Note Existence Validation** : Verifies that the referenced note exists in the system
  - Queries the note database to confirm the `instance_id` corresponds to an existing note record
  - Returns a descriptive error if the note is not found
  1. **Field Validation** : Ensures all required fields are provided and properly formatted
  - `instance_id` must be set on the `Note` effect
  - Both `key` and `value` must be provided
##  Example Usage 
###  Basic Usage 
    ```python
    from canvas_sdk.effects.note.note import Note
    # Create a metadata entry for note tracking
    note = Note(instance_id="803ce56a-350e-49a4-abae-019d9f5f24b2")
    effect = note.upsert_metadata(key="my_plugin:external_system_id", value="EXT-12345")
    ```
###  Example 
    ```python
    import json
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note.note import Note
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class NoteMetadataHandler(BaseHandler):
      """
      Adds metadata to notes when a plan command is updated.
      """
      RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__POST_UPDATE)
      def compute(self) -> list[Effect]:
        note_id = self.event.context["note"]["id"]
        command_id = self.event.target.id
        note = Note(instance_id=note_id)
        return [note.upsert_metadata(key="my_plugin:last_plan_update_command", value=str(command_id))]
    ```
###  Storing Multiple Metadata Entries 
    ```python
    import json
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note.note import Note
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class SigningMetadataHandler(BaseHandler):
      """
      Adds metadata to notes when they are signed.
      """
      RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
      def compute(self) -> list[Effect]:
        note_id = self.event.context["note"]["id"]
        state = self.event.context.get("note_state_change_event", {}).get("state")
        effects: list[Effect] = []
        if state == "SGN":
          note = Note(instance_id=note_id)
          # Store signing source
          effects.append(note.upsert_metadata(key="my_plugin:signing_source", value="protocol"))
          # Store additional context as JSON
          context_data = {
            "signed_by": self.event.context.get("actor", {}).get("id"),
            "protocol_version": "1.0"
          }
          effects.append(note.upsert_metadata(key="my_plugin:signing_context", value=json.dumps(context_data)))
        return effects
    ```
##  Best Practices 
###  Key Naming Conventions 
  1. **Use Descriptive Names** : Choose keys that clearly indicate the purpose of the metadata
  - Good: `external_system_id`, `workflow_stage`, `signing_source`
  - Avoid: `data1`, `temp`, `misc`
  1. **Namespace Your Keys** : Prefix keys with your plugin name to avoid collisions with other plugins
  - Example: `my_plugin:external_system_id`, `my_plugin:workflow_stage`, `my_plugin:signing_source`
###  Value Storage 
  1. **String Serialization** : All values are stored as strings. For complex data types:
         ```python
         import json
         from canvas_sdk.effects.note.note import Note
         note = Note(instance_id="803ce56a-350e-49a4-abae-019d9f5f24b2")
         complex_data = {"stage": "review", "approvers": ["user1", "user2"], "timestamp": "2025-01-15T10:30:00Z"}
         note.upsert_metadata(key="my_plugin:workflow_state", value=json.dumps(complex_data))
         ```
  2. **Boolean Values** : Store as "true" or "false" strings for consistency
         ```python
         from canvas_sdk.effects.note.note import Note
         needs_followup = True
         note = Note(instance_id="803ce56a-350e-49a4-abae-019d9f5f24b2")
         note.upsert_metadata(key="my_plugin:requires_followup", value="true" if needs_followup else "false")
         ```
##  Notes 
  - Metadata entries are note-specific and isolated - the same key can have different values for different notes
  - There is no built-in versioning; updating a key overwrites the previous value
  - The system does not enforce any schema on metadata values - validation is the responsibility of the implementing code

# Note Restrictions Effect

Source: https://docs.canvasmedical.com/sdk/effect-note-restrictions/

The `NoteRestrictionsEffect` and `NoteRestrictionsUpdatedEffect` allow plugins to restrict access to notes and push real-time permission updates to connected clients.
  - **`NoteRestrictionsEffect`** — returned by a plugin in response to a `GET_NOTE_RESTRICTIONS` event. It tells the Canvas UI whether the requesting user should see a banner, have the note content blurred, or have editing disabled.
  - **`NoteRestrictionsUpdatedEffect`** — emitted by a plugin at any time to signal that restrictions for a specific note have changed, causing all connected clients viewing that note to immediately refetch their restrictions.
* * *
##  NoteRestrictionsEffect 
###  How it works 
Every time a note is opened (or its restrictions are refetched), Canvas fires a `GET_NOTE_RESTRICTIONS` event targeting that note's external ID. Plugins that subscribe to this event can return a `NoteRestrictionsEffect` to control what the user sees.
If no plugin returns a `NoteRestrictionsEffect`, the note is unrestricted by default.
###  Event payload 
Property| Value| Description  
---|---|---  
`event.target.id`| `str` (UUID)| The `id` of the note being accessed. Use this to look up the note or its metadata.  
`event.actor.id`| `str` (int)| The database ID of the authenticated user requesting the note. Use `Staff.objects.filter(user__dbid=event.actor.id)` to resolve to a staff record.  
`event.context`| `{}`| Empty — no additional context is provided.  
###  Attributes 
Field| Type| Default| Description  
---|---|---|---  
`restrict_access`| `bool`| `False`| Whether the requesting user is restricted from editing this note.  
`blur_content`| `bool`| `False`| Whether the note body should be blurred for the requesting user.  
`banner_message`| `str` | `None`| `None`| Message shown in the warning banner at the top of the note. If `None`, a default "This note is currently restricted." message is displayed.  
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note.restrictions import NoteRestrictionsEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class NoteAccessHandler(BaseHandler):
        """Restrict access to notes based on custom business logic."""
        RESPONDS_TO = EventType.Name(EventType.GET_NOTE_RESTRICTIONS)
        def compute(self) -> list[Effect]:
            note_id = self.event.target.id
            actor_id = self.event.actor.id
            if not self.user_can_access(note_id, actor_id):
                return [
                    NoteRestrictionsEffect(
                        restrict_access=True,
                        blur_content=True,
                        banner_message="You do not have permission to view this note.",
                    ).apply()
                ]
            return []
        def user_can_access(self, note_id: str, actor_id: str) -> bool:
            # Custom access logic here
            ...
    ```
* * *
##  NoteRestrictionsUpdatedEffect 
###  How it works 
When a plugin performs an action that changes whether a note is restricted (e.g. writing an edit lock to `NoteMetadata`, updating an access rule), it can emit a `NoteRestrictionsUpdatedEffect`. Canvas will broadcast a WebSocket notification to all clients currently viewing that note, causing them to refetch their restrictions immediately — no page reload required.
###  Attributes 
Field| Type| Description  
---|---|---  
`note_id`| `str` (UUID)| The id of the note whose restrictions have changed.  
###  Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note.restrictions import NoteRestrictionsUpdatedEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import NoteMetadata
    class NoteAccessChangedHandler(BaseHandler):
        """Broadcast a real-time restriction update after note metadata changes."""
        RESPONDS_TO = EventType.Name(EventType.NOTE_METADATA_UPDATED)
        def compute(self) -> list[Effect]:
            note_id = (
                NoteMetadata.objects
                .filter(id=self.event.target.id)
                .values_list("note__id", flat=True)
                .first()
            )
            if not note_id:
                return []
            return [NoteRestrictionsUpdatedEffect(note_id=str(note_id)).apply()]
    ```
* * *
##  Common use cases 
  - **Concurrent edit protection** — prevent multiple providers from editing the same note simultaneously; the second user sees a banner and disabled inputs until the first provider's session expires.
  - **Role-based note type access** — restrict certain note types (e.g. sensitive clinical notes) to a specific set of staff members.
  - **Sensitive note hiding** — blur the content of notes containing sensitive information for users who should not see the full details.
For full working implementations of these patterns, see the [**note-timeline-restrictions**](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/note-timeline-restrictions) example plugin, which covers concurrent edit locking, role-based access via a dashboard, automatic lock expiry via a cron job, and real-time updates.

# Note Effects

Source: https://docs.canvasmedical.com/sdk/effect-notes/

The Canvas SDK provides effects to facilitate creating, updating, and managing **visit notes** , **appointments** , and **schedule events**. Below you'll find detailed documentation for each effect type and their operations.
##  Note Effect 
The `Note` effect facilitates the creation and updating of visit notes for patients.
###  Create Note 
Creates a new note. Can be passed an optional UUID as `instance_id` from the `uuid.uuid4` library, or will be assigned one if not present. Passing a user-set UUID as the `instance_id` allows for [assigning commands to the note](/sdk/commands/#chaining-methods-with-a-user-set-uuid) in the same plugin action.
####  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`instance_id`| `UUID` or `str`| Identifier for the note| No  
`note_type_id`| `UUID` or `str`| Identifier for the note type| Yes  
`datetime_of_service`| `datetime.datetime`| When the service was provided| Yes  
`patient_id`| `str`| Identifier for the patient| Yes  
`practice_location_id`| `UUID` or `str`| Identifier for the practice location| Yes  
`provider_id`| `str`| Identifier for the provider| Yes  
`title`| `str` or `None`| Optional title for the note| No  
`supervising_provider_id`| `str` or `None`| Staff identifier for the supervising provider| No  
####  Implementation Details 
  - Validates that the note type exists and has an appropriate category
  - Ensures the patient exists in the system
  - Verifies that the practice location and provider are valid
  - If `supervising_provider_id` is provided, validates that the Staff record exists
####  Example Usage 
    ```python
    import datetime
    from canvas_sdk.effects.note.note import Note
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            note_effect = Note(
                note_type_id="note-type-uuid",
                datetime_of_service=datetime.datetime.now(),
                patient_id="patient-uuid",
                practice_location_id="practice-location-uuid",
                provider_id="provider-uuid"
            )
            return [note_effect.create()]
    ```
###  Update Note 
Updates an existing note. Only certain fields can be modified after creation.
####  Attributes 
Attribute| Type| Description| Required| Updatable  
---|---|---|---|---  
`instance_id`| `UUID` or `str`| Identifier of the note to update| Yes| No  
`title`| `str` or `None`| Updated title for the note| No| Yes  
`datetime_of_service`| `datetime.datetime`| Updated service date/time| No| Yes  
`practice_location_id`| `UUID` or `str`| Updated practice location| No| Yes  
`provider_id`| `str`| Updated provider| No| Yes  
`supervising_provider_id`| `str` or `None`| Staff identifier for the supervising provider| No| Yes  
**Note** : `patient_id` and `note_type_id` cannot be updated after creation.
####  Example Usage 
    ```python
    import datetime
    from canvas_sdk.effects.note.note import Note
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            note_effect = Note(instance_id="existing-note-uuid")
            note_effect.title = "Updated Consultation Notes"
            note_effect.datetime_of_service = datetime.datetime.now()
            return [note_effect.update()]
    ```
###  Fax Note 
Sends an existing note via fax to a specified recipient. This effect allows you to transmit patient notes to external healthcare providers or facilities.
####  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`note_id`| `UUID` or `str`| Identifier of the note to fax| Yes  
`recipient_name`| `str`| Name of the fax recipient| Yes  
`recipient_fax_number`| `str`| Fax number of the recipient. Should include the country code| Yes  
`include_coversheet`| `bool`| Whether to include a coversheet with the fax| No  
`subject`| `str` or `None`| Subject line for the coversheet (required if coversheet used)| No  
`comment`| `str` or `None`| Additional comments for coversheet (required if coversheet used)| No  
`location_id`| `UUID` or `str` or `None`| Practice location ID (required if coversheet used)| No  
####  Implementation Details 
  - Validates that the note exists in the system
  - If `include_coversheet` is `True`, the following fields become required:
    - `subject`: The subject line for the coversheet
    - `comment`: Additional comments to include on the coversheet
    - `location_id`: The practice location identifier (must exist in the system)
  - Validates that the practice location exists if provided
####  Example Usage 
    ```python
    from canvas_sdk.effects.fax.note import FaxNoteEffect
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):

##  Managing Appointment Labels 
Canvas supports adding up to 3 labels per appointment for categorization and workflow automation. Labels can be managed programmatically using the appointment label effects.
For detailed documentation on appointment label management, see [Appointment Label Effects](/sdk/effect-appointment-labels/).
###  Quick Example 
    ```python
    from canvas_sdk.effects.note.appointment import AddAppointmentLabel, RemoveAppointmentLabel
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.APPOINTMENT_LABEL_ADDED), EventType.Name(EventType.APPOINTMENT_LABEL_REMOVED)]
        def compute(self):
            # Add labels to an appointment
            add_effect = AddAppointmentLabel(
                appointment_id="appointment-uuid",
                labels={"URGENT", "FOLLOW_UP"}
            )
            # Remove labels from an appointment
            remove_effect = RemoveAppointmentLabel(
                appointment_id="appointment-uuid",
                labels={"CANCELLED"}
            )
            return [add_effect.apply(), remove_effect.apply()]
    ```
* * *
##  Validation 
All effects perform comprehensive validation before execution:
  1. **Entity Existence** : Validates that referenced entities (patients, providers, practice locations, note types) exist in the system
  2. **Type Compatibility** : Ensures note types are appropriate for the intended operation:
     - Visit notes cannot use `APPOINTMENT`, `SCHEDULE_EVENT`, `MESSAGE`, or `LETTER` note types
     - Schedule events must use `SCHEDULE_EVENT` note types
     - Appointments must use `ENCOUNTER` note types that are scheduleable
  3. **Field Requirement Enforcement** : The system validates conditional field requirements based on note type configurations:
     - **Patient Association Requirements** : For note types with `is_patient_required=True`, the system enforces that a valid patient ID is provided. This is particularly important for schedule events that may or may not be associated with specific patients.
     - **Custom Description Validation** : When a note type has `allow_custom_title=False`, the system prevents custom descriptions from being added. This ensures adherence to standardized naming conventions for certain types of appointments and events.
     - **Required Field Validation** : All required fields are checked for proper values and formats before the effect is executed.
  4. **Update Restrictions** : Certain fields cannot be modified after creation:
     - **Notes** : `patient_id` and `note_type_id` are immutable
     - **Appointments** : `patient_id` is immutable

# Observation Effect

Source: https://docs.canvasmedical.com/sdk/effect-observation/

The `Observation` effect provides a unified way to create and update clinical observations within the Canvas platform. Observations can include vitals (blood pressure, temperature, etc.), lab results, and other clinical measurements. The effect supports structured coding using standard terminologies (LOINC, SNOMED), components for multi-part measurements, and value codings for interpretation.
##  Attributes 
Name| Type| Description  
---|---|---  
`observation_id`| `str` or `UUID` or `None`| Unique identifier of an existing observation. Must be unset when creating; required when updating.  
`patient_id`| `str` or `None`| ID of the patient for this observation. Required when creating.  
`is_member_of_id`| `str` or `UUID` or `None`| Reference to a parent observation (for grouping related observations).  
`category`| `str` or `list[str]` or `None`| Category of observation (e.g., "vital-signs", "laboratory", "imaging"). Can be a single category or a list of categories.  
`units`| `str` or `None`| Unit of measure for the observation value (e.g., "mmHg", "mg/dL").  
`value`| `str` or `None`| The observation value as a string.  
`note_id`| `int` or `None`| ID of the note associated with this observation.  
`name`| `str` or `None`| Human-readable name for the observation. Required when creating.  
`effective_datetime`| `datetime` or `None`| Date and time when the observation was taken. Required when creating.  
`codings`| `list[CodingData]` or `None`| List of standardized codes identifying this observation (e.g., LOINC codes).  
`components`| `list[ObservationComponentData]` or `None`| List of components for multi-part observations (e.g., systolic and diastolic BP).  
`value_codings`| `list[CodingData]` or `None`| List of coded values for interpretation (e.g., "normal", "abnormal").  
##  Helper Classes

    ```
###  update() → Effect 
Update an existing observation.
  - **Effect Type:** `UPDATE_OBSERVATION`
  - **Payload:** `{ "data": { observation_id, <dirty_fields> } }`
  - Only fields marked dirty (modified on the model) are included in the update.
####  Validation 
  - `observation_id` is **required** and must reference an existing observation

  - **Effect Type:** `ENTER_IN_ERROR_OBSERVATION`
  - **Payload:** `{ "data": { observation_id } }`
  - Only `observation_id` is allowed; setting any other field will raise a validation error.
####  Validation 
  - `observation_id` is **required** and must reference an existing observation
  - All other fields must **not** be set (only `observation_id` is allowed)
  - The observation must not already be entered in error
  - The observation must not belong to a locked note
####  Example 
    ```python
    # Find an observation that was recorded incorrectly
    erroneous_obs = ObservationModel.objects.filter(patient_id=patient.id).first()
    # Mark it as entered in error
    error_observation = Observation(observation_id=erroneous_obs.id)
    effect_error = error_observation.enter_in_error()
    ```

# Patient Facility Address

Source: https://docs.canvasmedical.com/sdk/effect-patient-facility-address/

The `PatientFacilityAddress` effect enables the creation, updating, and deletion of patient facility address records within Canvas. Patient facility addresses link patients to healthcare facilities, with optional room number information. The address details are automatically populated from the linked facility.
You can either reference an existing facility by ID, or create a new facility inline by providing the facility details.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`id`| `str` or `UUID`| ID of the patient facility address (for update/delete)| Yes (update/delete)  
`patient_id`| `str` or `UUID`| ID of the patient| Yes (create)  
`facility_id`| `str` or `UUID`| ID of an existing facility to link| Yes (if not creating new)  
`facility_name`| `str`| Name of new facility to create| Yes (if creating new facility)  
`facility_npi_number`| `str`| NPI number for new facility| No  
`facility_phone_number`| `str`| Phone number for new facility| No  
`facility_fax_number`| `str`| Fax number for new facility| No  
`facility_active`| `bool`| Whether the new facility is active| No  
`facility_line1`| `str`| Street address line 1 for new facility| No  
`facility_line2`| `str`| Street address line 2 for new facility| No  
`facility_city`| `str`| City for new facility| Yes (if creating new facility)  
`facility_district`| `str`| District for new facility| No  
`facility_state_code`| `str`| State code for new facility (e.g., "CA", "NY")| Yes (if creating new facility)  
`facility_postal_code`| `str`| Postal code for new facility| Yes (if creating new facility)  
`room_number`| `str`| Room number at the facility| No  
`address_type`| `AddressType` or `str`| Type of address: "physical" or "both"| No (defaults to "physical")  
##  Facility Reference Options 
When creating a patient facility address, you must either:
  1. **Reference an existing facility** by providing `facility_id`
  2. **Create a new facility inline** by providing facility creation fields (`facility_name`, `facility_city`, `facility_state_code`, `facility_postal_code`)
> **Warning:** You cannot specify both `facility_id` and facility creation fields. Use one approach or the other.
###  Required Fields for Inline Facility Creation 
When creating a new facility inline, the following fields are required:
  - `facility_name`
  - `facility_city`
  - `facility_state_code`
  - `facility_postal_code`
##  Address Type 
The `address_type` field accepts the following values:
Value| Description  
---|---  
`physical`| Physical/street address (default)  
`both`| Both physical and mailing address  
##  Effect Methods 
###  `.create()`
Creates a new patient facility address. Requires `patient_id` and either `facility_id` or facility creation fields.
**Effect Type:** `CREATE_PATIENT_FACILITY_ADDRESS`
###  `.update()`
Updates an existing patient facility address. Requires `id` of the address to update.
**Effect Type:** `UPDATE_PATIENT_FACILITY_ADDRESS`
###  `.delete()`
Deletes an existing patient facility address. Requires `id` of the address to delete.
**Effect Type:** `DELETE_PATIENT_FACILITY_ADDRESS`
##  Validation 
The effect validates:
  - **Create** : `patient_id` is required and must reference an existing patient
  - **Create** : Either `facility_id` or facility creation fields must be provided (not both)
  - **Create** : If `facility_id` is provided, it must reference an existing facility
  - **Create** : If creating a new facility, all required facility fields must be provided
  - **Update/Delete** : `id` is required and must reference an existing patient facility address
  - **Update** : If updating facility, same rules apply as create (facility_id OR creation fields)
  - `address_type` must be "physical" or "both" if provided
##  Example Usage 
###  Creating with Existing Facility 
    ```python
    from canvas_sdk.effects.patient_facility_address import PatientFacilityAddress, AddressType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            effect = PatientFacilityAddress(
                patient_id="patient-uuid-here",
                facility_id="facility-uuid-here",
                room_number="101A",
                address_type=AddressType.PHYSICAL,
            )
            return [effect.create()]
    ```
###  Creating with New Facility 
    ```python
    from canvas_sdk.effects.patient_facility_address import PatientFacilityAddress, AddressType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            effect = PatientFacilityAddress(
                patient_id="patient-uuid-here",
                facility_name="Downtown Medical Center",
                facility_line1="123 Main Street",
                facility_line2="Suite 400",
                facility_city="Boston",
                facility_state_code="MA",
                facility_postal_code="02101",
                facility_phone_number="617-555-1234",
                facility_npi_number="1234567890",
                room_number="Room 205",
                address_type=AddressType.PHYSICAL,
            )
            return [effect.create()]
    ```
###  Updating an Existing Address 
    ```python
    from canvas_sdk.effects.patient_facility_address import PatientFacilityAddress
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            # Update to use a different existing facility
            effect = PatientFacilityAddress(
                id="existing-address-uuid",
                facility_id="new-facility-uuid",
                room_number="202B",
            )
            return [effect.update()]
    ```
###  Deleting an Address 
    ```python
    from canvas_sdk.effects.patient_facility_address import PatientFacilityAddress
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            effect = PatientFacilityAddress(
                id="existing-address-uuid",
            )
            return [effect.delete()]
    ```
##  Notes 
  - The address details (line1, line2, city, state, country, postal_code) displayed for a patient facility address are automatically populated from the linked facility's address information.
  - When a facility's address is updated, all linked patient facility addresses are automatically updated to match. This synchronization happens asynchronously and applies to line1, line2, city, district, state_code, postal_code, and country fields. Non-address changes to the facility (such as name, NPI number, or phone number) do not trigger this cascade.
  - When creating a new facility inline, the facility is created first, then linked to the patient facility address.
  - Room number is optional and can be used to specify the patient's specific room within the facility.

# Patient Group

Source: https://docs.canvasmedical.com/sdk/effect-patient-group/

The Canvas SDK provides effects for managing patient membership in groups. These effects are idempotent — adding a patient who is already a member or deactivating a patient who is not an active member will have no effect.
##  PatientGroupEffect 
An effect class for performing actions on a patient group. Instantiate it with a `group_id`, then call methods to add or deactivate members.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`group_id`| `UUID`| The id of the [patient group](/sdk/data-patient-group/)| Yes  
###  Methods 
####  `add_member(patient_ids: list[str]) -> Effect`
Ensures one or more patients are members of the group.
Parameter| Type| Description  
---|---|---  
`patient_ids`| `list[str]`| List of [patient](/sdk/data-patient/) ids to add to the group  
####  `deactivate_member(patient_ids: list[str]) -> Effect`
Ensures one or more patients are not active members of the group. If a patient is currently locked in the group, this effect will be ignored for that patient.
Parameter| Type| Description  
---|---|---  
`patient_ids`| `list[str]`| List of [patient](/sdk/data-patient/) ids to deactivate from the group  
###  Example Usage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_group import PatientGroupEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Patient, PatientGroup
    class AddMemberHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self) -> list[Effect]:
            """Add patients to a group."""
            patient = Patient.objects.get(id=self.target)
            group = PatientGroup.objects.first()
            effect = PatientGroupEffect(group_id=str(group.id))
            return [effect.add_member(patient_ids=[str(patient.id)])]
    class DeactivateMemberHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self) -> list[Effect]:
            """Deactivate a patient from a group."""
            patient = Patient.objects.get(id=self.target)
            group = PatientGroup.objects.first()
            effect = PatientGroupEffect(group_id=str(group.id))
            return [effect.deactivate_member(patient_ids=[str(patient.id)])]
    ```

# PatientMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-patient-metadata/

The `PatientMetadata` effect provides a flexible key-value storage system for patient-specific data within the Canvas system. This effect enables the creation and updating of custom metadata entries associated with patient records, allowing for extensible patient information storage beyond standard demographic fields.
##  Overview 
Patient metadata serves as a powerful extension mechanism for storing custom patient-related information that doesn't fit within the standard patient data model. It uses the `.upsert(value)` method to apply a value to the key attributed with the Metadata effect object.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`patient_id`| `str`| Id of the [Patient(/sdk/data-patient/)] record to associate metadata with| Yes  
`key`| `str`| Unique identifier for the metadata entry within the patient context| Yes  
##  Methods 
###  upsert(value: str) → Effect 
Creates or updates a metadata entry for the specified patient and key combination.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`value`| `str`| The metadata value to store| Yes  
####  Behavior 
  - If a metadata entry with the specified key already exists for the patient, it will be updated with the new value
  - If no entry exists, a new metadata entry will be created
##  Implementation Details 
###  Validation 
The effect performs comprehensive validation before execution:
  1. **Patient Existence Validation** : Verifies that the referenced patient exists in the system
  - Queries the patient database to confirm the `patient_id` corresponds to an existing patient record
  - Returns a descriptive error if the patient is not found
  1. **Field Validation** : Ensures all required fields are provided and properly formatted
  - Both `patient_id` and `key` must be non-empty strings
  - The `value` parameter in the `upsert` method must be provided
###  Data Structure 
The effect payload is structured as JSON with the following schema:
    ```json
    {
      "data": {
        "patient_id": "patient-id",
        "key": "metadata-key",
        "value": "metadata-value"
      }
    }
    ```
##  Example Usage 
###  Basic Usage 
    ```python
    from canvas_sdk.effects.patient_metadata import PatientMetadata
    # Create a metadata entry for patient preferences
    metadata = PatientMetadata(
        patient_id="550e8400e29b41d4a716446655440000",
        key="preferred_contact_time"
    )
    # Upsert the metadata value
    effect = metadata.upsert("morning")
    ```
###  Metadata Parsing Example 
    ```python
    import json
    import re
    from canvas_sdk.effects.patient_metadata import PatientMetadata
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    class NarrativeMetadataExtractor(BaseHandler):
      """
      Extracts structured metadata from clinical narratives.
      """
      RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__POST_UPDATE)
      def compute(self):
        patient_id = self.event.context["patient"]["id"]
        narrative = self.event.context.get("fields", {}).get("narrative", "")
        # Extract key-value pairs from narrative text
        # Pattern: key=somekey*value=somevalue
        key_match = re.search(r'key=([^*#_\s]+)', narrative)
        value_match = re.search(r'value=([^*#_\s]+)', narrative)
        if not (key_match and value_match):
          return []
        key = key_match.group(1)
        value = value_match.group(1)
        # Create metadata effect
        metadata = PatientMetadata(
          patient_id=patient_id,
          key=key
        )
        return [metadata.upsert(value)]
    ```
##  Best Practices 
###  Key Naming Conventions 
  1. **Use Descriptive Names** : Choose keys that clearly indicate the purpose of the metadata
  - Good: `external_mrn`, `preferred_pharmacy_id`, `risk_score_diabetes`
  - Avoid: `data1`, `temp`, `misc`
  1. **Namespace Your Keys** : When building integrations or modules, prefix keys to avoid collisions
  - Example: `integration_patient_id`, `module_diabetes_last_a1c_date`
###  Value Storage 
  1. **String Serialization** : All values are stored as strings. For complex data types:
         ```python
         # Storing JSON data
         import json
         from canvas_sdk.effects.patient_metadata import PatientMetadata
         metadata = PatientMetadata(
             patient_id="550e8400e29b41d4a716446655440000",
             key="result"
         )
         complex_data = {"scores": [85, 92, 78], "average": 85.0}
         metadata.upsert(json.dumps(complex_data))
         ```
  2. **Boolean Values** : Store as "true" or "false" strings for consistency
         ```python
         from canvas_sdk.effects.patient_metadata import PatientMetadata
         patient_consented = False
         metadata = PatientMetadata(
             patient_id="550e8400e29b41d4a716446655440000",
             key="boolean_value"
         )
         metadata.upsert("true" if patient_consented else "false")
         ```
##  Notes 
  - Metadata entries are patient-specific and isolated - the same key can have different values for different patients
  - There is no built-in versioning; updating a key overwrites the previous value
  - The system does not enforce any schema on metadata values - validation is the responsibility of the implementing code

# Patient Timeline

Source: https://docs.canvasmedical.com/sdk/effect-patient-timeline/

The Canvas SDK allows you to configure which note types a patient's chart shows and which the **New Note** button offers.
Both are controlled by the `PatientTimelineEffect` class, returned in response to the `PATIENT_TIMELINE__GET_CONFIGURATION` event, which fires when a patient's chart is loaded.
##  Excluding Note Types 
###  Attributes 
Attribute|  | Type| Description  
---|---|---|---  
`excluded_note_types`| optional| list[str]| A list of [`NoteType.unique_identifier`](/sdk/data-note/#notetype) values (UUIDs) to exclude from the patient's timeline. Defaults to `[]`.  
`allowed_new_note_types`| optional| list[str] | None| An allow-list of [`NoteType.unique_identifier`](/sdk/data-note/#notetype) values the **New Note** button may offer. `None` (the default) means no constraint; `[]` offers nothing, which hides the button. See Restricting note creation.  
The two attributes differ in scope, and you will usually want only one of them:
| `excluded_note_types`| `allowed_new_note_types`  
---|---|---  
direction| deny-list| allow-list  
existing notes on the timeline| **hidden**|  visible  
timeline's note type filter| type removed| type still offered  
**New Note** button| type removed| restricted to the list  
direct permalink to such a note| permission error| unaffected  
several plugins respond| **unioned**| **unioned**  
###  Example Usage 
The `excluded_note_types` list must contain `unique_identifier` values from the `NoteType` model. Each `NoteType` has a `unique_identifier` (UUID) that you can look up by querying the model:
    ```python
    from canvas_sdk.v1.data.note import NoteType
    # Find the unique_identifier for a note type by name
    note_type = NoteType.objects.get(name="Office visit")
    note_type.unique_identifier  # e.g. UUID("a3b9c1d2-...")
    # Or list all note types with their unique_identifiers
    for nt in NoteType.objects.all():
        print(f"{nt.name}: {nt.unique_identifier}")
    ```
Then use those `unique_identifier` values in the effect:
    ```python
    from canvas_sdk.effects.patient.timeline import PatientTimelineEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.note import NoteType
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PATIENT_TIMELINE__GET_CONFIGURATION)]
        def compute(self):
            # Use unique_identifier
            office_visit = NoteType.objects.get(name="Office visit", is_active=True)
            lab_visit = NoteType.objects.get(name="Lab visit", is_active=True)
            effect = PatientTimelineEffect(
                excluded_note_types=[
                    str(office_visit.unique_identifier),
                    str(lab_visit.unique_identifier),
                ]
            )
            return [effect.apply()]
    ```
###  Behavior 
> **Info:** **Chart Review notes cannot be excluded.** Even if a `CHART_REVIEW` note type is included in the `excluded_note_types` list, it will always be shown on the timeline. The system automatically removes it from any exclusion list.
  - **Permalink access** : If a user tries to directly access a note whose type has been excluded, they will receive a permission error.
  - **Multiple plugins** : If multiple plugins respond to the `PATIENT_TIMELINE__GET_CONFIGURATION` event, the excluded note types from all responses are combined.
  - **Note creation** : An excluded note type is also removed from the patient chart's **New Note** button and from the timeline's note type filter, so users cannot pick that type when creating a note. This governs what the UI offers — it does not reject a note of an excluded type created directly through the API.
> **Info:** **To restrict note creation without hiding existing notes:** `excluded_note_types` hides a patient's existing notes of that type _and_ removes the type from the **New Note** button. If you only want to restrict what the button offers, while leaving the patient's history visible and filterable, use `allowed_new_note_types` instead.
##  Restricting note creation 
`allowed_new_note_types` is an **allow-list** of the note types the **New Note** button may offer. It affects note _creation_ only: existing notes of a withheld type stay on the timeline, and the timeline's note type filter keeps offering that type, so a provider can still see and filter the history they are being stopped from adding to.
A common use is limiting which note types a given provider can originate. An organization might want only certain staff sending text messages to a patient, for example: the **New Note** button offers the Message type to those roles and withholds it from everyone else, while every provider can still read the messages already on the patient's chart and filter the timeline by them.
Inactive and deprecated note types are never offered, whether or not a plugin responds.
The example below allow-lists by the staff member's clinical role, so a nurse can send a message or log a phone call while only a physician is offered an office visit.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient.timeline import PatientTimelineEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.note import NoteType
    from canvas_sdk.v1.data.staff import Staff
    ALLOWED_BY_ROLE = {
        "MD": ["Office visit", "Phone call", "Message"],
        "RN": ["Phone call", "Message"],
    }
    class RestrictNewNoteTypes(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_TIMELINE__GET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            staff = Staff.objects.filter(user__dbid=self.event.actor.id).first()
            role = staff.top_role_abbreviation if staff else None
            allowed_names = ALLOWED_BY_ROLE.get(role or "", ["Message"])
            note_types = NoteType.objects.filter(is_active=True, name__in=allowed_names)
            return [
                PatientTimelineEffect(
                    allowed_new_note_types=[str(nt.unique_identifier) for nt in note_types]
                ).apply()
            ]
    ```
To hide the button entirely, return an empty allow-list:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient.timeline import PatientTimelineEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class HideNewNoteButton(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_TIMELINE__GET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [PatientTimelineEffect(allowed_new_note_types=[]).apply()]
    ```
###  Behavior 
What your plugin returns| Result  
---|---  
attribute omitted, or `None`| the full note type list, unchanged  
`allowed_new_note_types=[...]`| only those note types are offered  
`allowed_new_note_types=[]`| nothing is offered, so the **New Note** button is hidden entirely  
  - **Multiple plugins** : allow-lists from all responses are combined, the same way exclusions are. Note the consequence: a second plugin returning an allow-list _widens_ what a first one permits, so a restriction is only as tight as the most permissive plugin responding.
  - **Combined with exclusions** : a note type excluded via `excluded_note_types` stays out of the button even if the allow-list names it. Exclusions win because they affect far more — the timeline, the note type filter and permalink access — so they are the safer outcome when a plugin names the same type in both.
  - **Chart Review** : unlike exclusions, `CHART_REVIEW` is _not_ force-allowed here. Force-allowing it would make "nothing available" unreachable and the button could never be hidden.
  - **Plugin failures** : if the plugin runner cannot be reached, the note type list is left unconstrained rather than emptied.
> **Warning:** **This is a workflow guardrail, not an access control.** It governs what the **New Note** button offers. It does not reject a note of a restricted type created directly through the API. Do not rely on it to enforce access to sensitive note types — see [Note Restrictions](/sdk/effect-note-restrictions/) for controlling access to notes.
> **Info:** **Note types are configured per instance.** The names above are illustrative, so check what exists on your instance before matching on `name` — a name that does not exist simply matches nothing, silently shortening your allow-list. A `unique_identifier` is generated per instance too, so it cannot be hard-coded in a plugin meant to run on more than one; look the note types up at runtime and keep the mapping configurable. An identifier that does not exist raises a `ValidationError` rather than failing quietly.
###  Validation 
  - All provided UUIDs, in either attribute, must correspond to existing [NoteType](/sdk/data-note/#notetype) records in the system. If a note type UUID does not exist, a `ValidationError` will be raised with a message indicating which note type was not found.
  - Values that are not valid UUIDs will also raise a `ValidationError`.

##  PatientContactPoint 
The `PatientContactPoint` dataclass represents various methods of contacting the patient.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`system`| `ContactPointSystem`| Type of contact (e.g., phone, email)| Yes  
`value`| `str`| The contact information value (e.g., phone number, email address)| Yes  
`use`| `ContactPointUse`| Purpose of the contact point (e.g., home, work)| Yes  
`rank`| `int`| Priority order of contact methods| Yes  
`has_consent`| `bool` or `None`| Whether consent has been given to use this contact method| No  
##  PatientContact 
The `PatientContact` dataclass represents one of the patient's contacts — an emergency contact, next-of-kin, or other related person.
A contact identifies its person in one of two ways, and you must supply one of them: either **inline** , by giving a `name` (with optional phone, email and comments), or by **reference** , by pointing `related_patient` at another Canvas patient. The reference form is what links two patients to each other, and Canvas displays such a contact from the referenced patient's own record rather than from the contact row.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`name`| `str` or `None`| The contact's name, when the contact holds the person's details inline| One of `name` or `related_patient`  
`related_patient`| `str`, `uuid.UUID` or `None`| The patient id of an existing Canvas patient this contact refers to, used instead of `name`| One of `name` or `related_patient`  
`contact_identifier`| `str`, `uuid.UUID` or `None`| Identifies an existing contact. Omit it to add a contact; supply it to modify or remove one. See Managing patient contacts| No  
`phone_number`| `str` or `None`| The contact's phone number. Exactly 10 digits| No  
`email`| `str` or `None`| The contact's email address| No  
`comments`| `str` or `None`| Free-text notes about the contact| No  
`categories`| list[PatientContactCategory] or `None`| The contact's relationship categories| No  
`inactive`| `bool` or `None`| Set with `contact_identifier` to remove the contact| No  
##  PatientContactCategory 
The `PatientContactCategory` dataclass expresses a contact's relationship to the patient — emergency contact, next-of-kin, and so on — as a coding.
All three fields are required, and the coding must already exist in the instance. Look one up with the [ContactCategory](/sdk/data-patient/#contactcategory) data model rather than composing a coding by hand; a coding the instance does not have raises a validation error instead of being created.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`code`| `str`| The category code (e.g., `"EMC"` for an emergency contact)| Yes  
`code_system`| `str`| The coding system the code belongs to (e.g., `"INTERNAL"`)| Yes  
`name`| `str`| The category's display name (e.g., `"Emergency contact"`)| Yes  
##  PatientExternalIdentifier 
The `PatientExternalIdentifier` dataclass represents an external identifier (ID) associated with the patient. An example would be the unique patient ID for a third party system integrated with Canvas EMR.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`system`| `str`| URL of the system of origin for the external ID (e.g., `http://hl7.org/fhir/sid/us-ssn`)| Yes  
`value`| `str`| The external ID or membership number/value| Yes  
##  PatientAddress 
The `PatientAddress` dataclass represents a patient's address information.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`line1`| `str`| Street address line 1| Yes  
`line2`| `str` or `None`| Street address line 2| No  
`city`| `str`| City name| Yes  
`state_code`| `str`| State code (e.g., "CA", "NY")| Yes  
`postal_code`| `str`| Postal/ZIP code| Yes  
`country`| `str`| Country code| Yes  
`use`| `AddressUse`| Address type (e.g., home, work)| Yes  
> **Warning:** Address updates are **replace-based**. When updating a patient's addresses, the provided address list will completely replace all existing addresses. If you provide an empty list, all existing addresses will be deleted.
##  PatientPreferredPharmacy 
The `PatientPreferredPharmacy` dataclass represents a patient's preferred pharmacy, and if it's their default pharmacy.
Attribute| Type| Description| Required  
---|---|---|---  
`ncpdp_id`| `str`| The ncpdp ID of the pharmacy| Yes  
`default`| `bool`| True if it's the default pharmacy| Yes  
##  PatientMetadata 
The `PatientMetadata` dataclass represents a custom key-value pair for a patient.
Attribute| Type| Description| Required  
---|---|---|---  
`key`| `str`| The key of the metadata| Yes  
`value`| `str`| The value of the metadata| Yes  
##  Implementation Details 
  - **Creation** : Creates new patient records. By default the server generates the patient id, but you may supply your own `patient_id` — see Supplying a patient id on creation
  - **Updates** : Updates existing patient records when `patient_id` is provided
  - Validates that referenced practice locations exist in the system
  - Verifies that referenced healthcare providers exist in the system
  - Structures contact information through the `PatientContactPoint` dataclass
  - Structures the patient's contacts through the `PatientContact` dataclass, added or modified per entry according to `contact_identifier` — see Managing patient contacts
  - Structures external identifier through the `PatientExternalIdentifier` dataclass
  - Structures address information through the `PatientAddress` dataclass
  - Structures metadata through the `PatientMetadata` dataclass

            return [updated_patient.update()]
    ```
###  Marking a Patient as Inactive or Deceased 
    ```python
    from canvas_sdk.effects.patient import Patient
    from canvas_sdk.handlers.base import BaseHandler
    import datetime
    class MyHandler(BaseHandler):
        def compute(self):
            # Mark a patient as inactive
            inactive_patient = Patient(
                patient_id="existing-patient-uuid",
                active=False
            )
            return [inactive_patient.update()]
    class DeceasedPatientHandler(BaseHandler):
        def compute(self):
            # Record a patient's death
            deceased_patient = Patient(
                patient_id="existing-patient-uuid",
                deceased=True,
                deceased_datetime=datetime.datetime(2025, 3, 14, 12, 0, 0),
                deceased_cause="Natural causes",
                deceased_comment="Pronounced at home."
            )
            return [deceased_patient.update()]
    ```
##  Supplying a patient id on creation 
By default, Canvas generates the patient id (`patient_id`) when you create a patient. You can supply your own instead by passing a 32-character hex string (a UUID4 with its hyphens removed) in the `patient_id` parameter of `Patient`. This lets your plugin generate the id up front and reuse it for follow-up, patient-scoped effects — such as notes or commands — in the same plugin execution, without reading the id back first. It works the same way Notes and Commands accept a pre-generated id.
A supplied id must be a well-formed patient id: a 32-character lowercase hex string, which is a UUID4 with its hyphens removed. Use `generate_patient_id()` to produce one rather than building the format by hand. An id in any other format — for example, a hyphenated or uppercase UUID — raises a validation error on `create()`, as does an id that already belongs to an existing patient. Since `generate_patient_id()` returns a fresh, well-formed id, it satisfies both requirements. If you omit `patient_id`, the server generates the id as before, so existing plugins are unaffected.
Because you generate the id up front, you can also return it to the caller from a [SimpleAPI](/sdk/handlers-simple-api-http/) endpoint — so a client creating the patient gets the id back in the response instead of having to look it up afterward. This example authenticates with the [`APIKeyAuthMixin`](/sdk/handlers-simple-api-http/), which expects a `simpleapi-api-key` secret declared in your manifest:
    ```python
    from canvas_sdk.effects.patient import Patient, generate_patient_id
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyAuthMixin, SimpleAPIRoute
    class CreatePatientAPI(APIKeyAuthMixin, SimpleAPIRoute):
        PATH = "/patients"
        def post(self) -> list[Response]:
            body = self.request.json()
            new_patient_id = generate_patient_id()
            patient = Patient(
                patient_id=new_patient_id,
                first_name=body["first_name"],
                last_name=body["last_name"],
            )
            # `new_patient_id` can be reused for follow-up patient-scoped effects in
            # the same execution, and is returned so the caller has it immediately
            # without a follow-up lookup.
            return [
                patient.create(),
                JSONResponse({"patient_id": new_patient_id}, status_code=201),
            ]
    ```
##  Managing patient contacts 
The `contacts` field writes the patient's contacts — emergency contacts, next-of-kin, and other related persons. What happens to each entry is decided by **`contact_identifier`** , not by whether you called `create()` or `update()`:
`contact_identifier`| `inactive`| Result  
---|---|---  
omitted| omitted| The contact is **added**  
supplied| omitted| The contact it names is **modified**  
supplied| `True`| The contact it names is **removed**  
omitted| `True`| Validation error — there is no contact to remove  
So `Patient(...).update()` adds a contact to a patient that already exists, which is the usual case for a plugin populating contacts after intake. Re-sending an identical contact matches the existing one rather than adding a second, so a handler that re-emits the same contact on every event will not accumulate duplicates. On an update, a `contact_identifier` that names no contact on that patient is treated as a mistake and raises rather than being added.
Contacts you leave out of the list are **left alone**. Unlike `addresses`, this field is not replace-based: omitting a contact never deletes it, and removal is always explicit through `inactive`.
An update writes only the fields you send, so changing a phone number does not blank the email or the comments. `name` (or `related_patient`) is the exception — every contact that is not a removal needs one, so resend the existing value when you are changing something else. Pass an empty string to clear a stored value deliberately.
    ```python
    from canvas_sdk.effects.patient import Patient, PatientContact, PatientContactCategory
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data import ContactCategory
    class MyHandler(BaseHandler):
        def compute(self):
            # Look the coding up rather than composing one — an unknown coding raises.
            emergency = ContactCategory.objects.get(code="EMC")
            category = PatientContactCategory(
                code=emergency.code,
                code_system=emergency.system,
                name=emergency.name,
            )
            # No contact_identifier, so this adds a contact.
            patient = Patient(
                patient_id="existing-patient-id",
                contacts=[
                    PatientContact(
                        name="Jane Doe",
                        phone_number="5551234567",
                        email="jane@example.com",
                        comments="Primary emergency contact",
                        categories=[category],
                    )
                ],
            )
            return [patient.update()]
    ```
###  Linking one patient to another 
Setting `related_patient` to another patient's key makes that patient the contact. Because your plugin can supply the patient id on creation, it knows the key before the patient exists — so it can create a patient and reference it from a later effect in the same execution:
    ```python
    from canvas_sdk.effects.patient import Patient, PatientContact, generate_patient_id
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            spouse_key = generate_patient_id()
            spouse = Patient(
                patient_id=spouse_key,
                first_name="Alex",
                last_name="Doe",
            )
            # References a patient the previous effect creates. Effects are applied in
            # order, so the key resolves by the time this one is written.
            patient = Patient(
                patient_id="existing-patient-id",
                contacts=[
                    PatientContact(
                        related_patient=spouse_key,
                        comments="Spouse — also a patient in Canvas",
                    )
                ],
            )
            return [spouse.create(), patient.update()]
    ```
A `related_patient` contact carries no name of its own; Canvas shows the referenced patient's details instead.
###  Removing a contact 
A removal needs the `contact_identifier` of the contact to remove and nothing else — no name or related patient, since neither is meaningful on a delete. Read the identifier from the [PatientContactPerson](/sdk/data-patient/#patientcontactperson) data model:
    ```python
    from canvas_sdk.effects.patient import Patient, PatientContact
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data import PatientContactPerson
    class MyHandler(BaseHandler):
        def compute(self):
            patient_key = "existing-patient-key"
            contact = PatientContactPerson.objects.filter(
                patient__id=patient_key, name="Jane Doe"
            ).first()
            if contact is None:
                return []
            patient = Patient(
                patient_id=patient_key,
                contacts=[
                    PatientContact(contact_identifier=str(contact.id), inactive=True)
                ],
            )
            return [patient.update()]
    ```
A single `contacts` list may mix all of these — additions, modifications and removals travel together in one effect.
##  Setting Race and Ethnicity 
`biological_race_codes` and `cultural_ethnicity_codes` each accept a list of code strings drawn from the [CDC Race and Ethnicity CodeSystem (CDCREC)](https://hl7.org/fhir/us/core/STU3.1.1/CodeSystem-cdcrec.html) — the same code set used by the [FHIR Patient API](/api/patient/). You can set both fields when creating or updating a patient, and you can supply more than one code per field.
Canvas recognizes the full CDCREC code set — both the OMB top-level categories below and the more specific detailed codes that roll up to them (for example, the race code `2108-9` "European" rolls up to `2106-3` "White", and the ethnicity code `2148-5` "Mexican" rolls up to `2135-2` "Hispanic or Latino"). The categories below are the most common values; see the CodeSystem for the complete list of detailed codes.
**Race** (`biological_race_codes`) — OMB top-level categories:
Code| Description  
---|---  
`1002-5`| American Indian or Alaska Native  
`2028-9`| Asian  
`2054-5`| Black or African American  
`2076-8`| Native Hawaiian or Other Pacific Islander  
`2106-3`| White  
`2131-1`| Other Race  
**Ethnicity** (`cultural_ethnicity_codes`) — OMB top-level categories:
Code| Description  
---|---  
`2135-2`| Hispanic or Latino  
`2186-5`| Not Hispanic or Latino  
    ```python
    from canvas_sdk.effects.patient import Patient
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            patient = Patient(
                patient_id="existing-patient-uuid",
                biological_race_codes=["2106-3"],      # White
                cultural_ethnicity_codes=["2186-5"]    # Not Hispanic or Latino
            )
            return [patient.update()]
    ```
##  Validation 
The effect performs validation before execution to ensure data integrity:
  1. **Required Fields** :
     - For creation: Validates that mandatory fields like `first_name` and `last_name` are provided
     - For updates: Requires `patient_id` to be provided and verifies the patient exists in the database
  2. **Referenced Entity Validation** : Confirms that any referenced entities exist in the system:
     - Verifies that the specified default practice location exists
     - Ensures that the specified default provider exists
  3. **Data Format Validation** : Ensures that provided values conform to expected formats:
     - Date fields must be valid dates
     - Enumerated types like `PersonSex`, `ContactPointSystem`, and `ContactPointUse` must contain valid values
     - On creation, if `patient_id` is supplied it must be a well-formed patient id (a 32-character hex string); otherwise validation raises
     - On creation, a supplied `patient_id` must not already belong to an existing patient; a duplicate id raises a validation error
  4. **Update-Specific Validation** :
     - Validates that the patient exists before attempting updates
  5. **Contact Validation** (see Managing patient contacts):
     - Every contact that is not a removal must carry either `name` or `related_patient`
     - A removal (`inactive=True`) must carry `contact_identifier`
     - `contact_identifier` and `related_patient` must be UUIDs; on an update, `contact_identifier` must name a contact that belongs to this patient, and `related_patient` must name an existing patient
     - `phone_number` must be exactly 10 digits, and `email` must be a valid email address
     - `PatientContactCategory` requires `code`, `code_system` and `name`, and the coding must already exist in the instance — an unknown coding raises rather than being created

# Protocol Card

Source: https://docs.canvasmedical.com/sdk/effect-protocol-cards/

Protocol cards appear on the right-hand-side of a patient's chart, and can be accessed by clicking on the Protocols filter button in the filter menu.
![protocol card](/assets/images/protocol-card.png)
A Protocol card consists of three main parts:
  - A title, which appears at the top in bold
  - A narrative, which appears just below the title to add any additional clarifying information
  - A list of recommendations, which each have a title and optionally a button that can either:
    - open a new tab and navigate to another site
    - insert commands into a note
Name| Type| Required| Description  
---|---|---|---  
`patient_id`|  _string_| `true` (if `patient_filter` is not included)| The id of the [patient](/sdk/data-patient/)  
`patient_filter`|  _dict_| `true` (if `patient_id` is not included)| Patient queryset filters to apply the effect to multiple patients. For example, `{"active": True}` will apply to the effect to all active patients  
`key`|  _string_| `true`| A unique identifier for the protocol card  
`title`|  _string_| `true`| The title for the protocol card, which appears at the top in bold  
`narrative`|  _string_| `false`| The narrative for the protocol card, which appears just below the title  
`can_be_snoozed`|  _boolean_| `false`| Whether the protocol card can be snoozed, defaults to `false`  
`status`| Status| `false`| The status of the protocol card, defaults to `Status.DUE`  
`recommendations`| list[Recommendation]| `false`| The recommendations to appear in the protocol card  
`feedback_enabled`|  _boolean_| `false`| Whether users can provide feedback for the protocol card in Settings, defaults to `false`  
`due_in`|  _integer_| `false`| The number of days until the protocol card will be considered due for the patient, defaults to `-1` for already due  
|  |  |   
###  Recommendation 
Attribute| Type| Required| Description  
---|---|---|---  
`title`|  _string_| `true`| The description of the recommendation  
`button`|  _string_| `false`| The text to appear on the button  
`href`|  _string_| `false`| The url for the button to navigate to  
`commands`| list[Command]| `false`| The commands to be inserted  
###  Status 
Enum| Value  
---|---  
`DUE`| due  
`SATISFIED`| satisfied  
`NOT_APPLICABLE`| not_applicable  
`PENDING`| pending  
`NOT_RELEVANT`| not_relevant  
|   
To include a command recommendation you can:
  - import the command from the [commands module](/sdk/commands/), instantiate the command with all the values you wish to populate, and then call `.recommend(title: str = "", button: str | None)` on the command to generate the recommendation that you can append to the protocol card's recommendations. Keep in mind that, at the moment, not all commands are supported for command insertion. See below for the list of supported commands.
  - instantiate the command as above, and then pass it in a list to the `commands` attribute of a recommendation.
</br> </br>
For non-command recommendations, you can either use the `Recommendation` class, or the `.add_recommendation(title: str = "", button: str = "", href: str | None)` method on the protocol card.
**Example** :
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from datetime import date
    from canvas_sdk.effects.protocol_card import ProtocolCard, Recommendation
    from canvas_sdk.commands import DiagnoseCommand, PlanCommand
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_UPDATED)
        def compute(self):
            diagnose = DiagnoseCommand(
                icd10_code="I10",
                background="feeling bad for many years",
                approximate_date_of_onset=date(2020, 1, 1),
                today_assessment="still not great",
            )
            plan = PlanCommand(
                narrative="Follow up in 2 weeks",
            )
            p = ProtocolCard(
                patient_id=self.target,
                key="testing-protocol-cards",
                title="This is a ProtocolCard title",
                narrative="this is the narrative",
                status=ProtocolCard.Status.DUE,
                recommendations=[
                  Recommendation(title="this recommendation has no action, just words!"),
                  Recommendation(title="this recommendation inserts multiple commands", button="add commands", commands=[diagnose, plan])
                ],
            )
            p.add_recommendation(
                title="this is a recommendation", button="go here", href="https://canvasmedical.com/"
            )
            p.recommendations.append(diagnose.recommend(title="this inserts a diagnose command"))
            p.recommendations.append(title="new recommendation", button="start", commands=[diagnose])
            return [p.apply()]
    ```
To apply the effect to all active patients on plugin create and plugin update, you would include the plugin create and update events in `RESPONDS_TO`. And when responding to one of the plugin events you would use `patient_filter` instead of `patient_id` for the ProtocolCard.
    ```python
    from canvas_sdk.effects.protocol_card import ProtocolCard, Recommendation
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from datetime import date
    from canvas_sdk.effects.protocol_card import ProtocolCard, Recommendation
    from canvas_sdk.commands import DiagnoseCommand
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.PATIENT_UPDATED),
            EventType.Name(EventType.PLUGIN_CREATED),
            EventType.Name(EventType.PLUGIN_UPDATED),
        ]
        def compute(self):
            p = ProtocolCard(
                key="testing-protocol-cards",
                title="This is a ProtocolCard title",
                narrative="this is the narrative",
                can_be_snoozed=True,
                recommendations=[
                    Recommendation(title="this recommendation has no action, just words!")
                ],
            )
            p.add_recommendation(
                title="this is a recommendation", button="go here", href="https://canvasmedical.com/"
            )
            diagnose = DiagnoseCommand(
                icd10_code="I10",
                background="feeling bad for many years",
                approximate_date_of_onset=date(2020, 1, 1),
                today_assessment="still not great",
            )
            p.recommendations.append(diagnose.recommend(title="this inserts a diagnose command"))
            if self.event.type in [EventType.PLUGIN_CREATED, EventType.PLUGIN_UPDATED]:
                p.patient_filter = {"active": True}
            else:
                p.patient_id = self.target
            return [p.apply()]
    ```

# Questionnaires

Source: https://docs.canvasmedical.com/sdk/effect-questionnaires/

The Canvas SDK includes functionality for handling questionnaire-related events.
##  Creating a Questionnaire 
Creating a questionnaire via the SDK requires current requires defining a YAML template and referencing it in your `CANVAS_MANIFEST.json` file. Read more [here](/sdk/questionnaires/).
##  Creating a Questionnaire Result 
The `CreateQuestionnaireResult` effect allows you to create custom scoring of questionnaires in Canvas. It adds a narrative to the command in the UI and can appear in the Social Determinants section of the left side of the chart if the questionnaire is configured to show in that section (see [here](/sdk/questionnaires) for how to control setting `display_result_in_social_history_section` for questionnaires).
###  Attributes 
Attribute| Required| Type| Description  
---|---|---|---  
interview_id| Yes| string| The id of the interview to associate the result with.  
score| Yes| float| The numerical score of the questionnaire result.  
abnormal| No| bool| Whether the result is considered abnormal. Defaults to `False`.  
narrative| No| string| A text description of the result and any recommended follow-up actions. Defaults to an empty string.  
code_system| Yes*| string| The code system used to identify the questionnaire (e.g., `"INTERNAL"`).  
code| Yes*| string| The code identifying the questionnaire within the code system (e.g., `"mchat_scoring"`).  
*Note: Questionnaire Results create an associated Observation record. The `code` and `code_system` fields are required in order to distinguish the Observation results.
###  Example 
**Note:** This example assumes that an M-CHAT questionnaire created and loaded into the Canvas instance.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.questionnaire_result import CreateQuestionnaireResult
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.command import Command
    class MChatQuestionnaireResult(BaseHandler):
        """
        Return a CreateQuestionnaireResult effect in response to a committed Questionnaire Command that
        contains questions coded for the M-CHAT questionnaire.
        """
        RESPONDS_TO = [EventType.Name(EventType.QUESTIONNAIRE_COMMAND__POST_COMMIT)]
        MCHAT_CODE_SYSTEM = "INTERNAL"
        MCHAT_CODE = "mchat_scoring"
        def compute(self) -> list[Effect]:
            # Get the interview object, which will be the anchor object on the Questionnaire command.
            command = Command.objects.get(id=self.event.target.id)
            interview = command.anchor_object
            if not interview.committer:
                return []
            # Return no effects if the interview has no questions that are coded as M-CHAT questions

# Redirect

Source: https://docs.canvasmedical.com/sdk/effect-redirect/

The `RedirectEffect` tells the Canvas frontend to navigate the browser to a destination. The plugin returns the effect from a handler and the frontend performs a full-page navigation. The headline use case is sending a user onward after a note is signed — for example, navigating back to a work queue to pick up the next patient.
A redirect is delivered only to the **acting user** who triggered the handler — and only to that user's browser. Because of that, it takes effect only when the handler runs in the context of a real user with an active browser session. Return it from user-initiated handlers — a note state-change (sign/lock) handler, an action-button handler, an application handler, or an authenticated [SimpleAPI](/sdk/handlers-simple-api/) call. If a handler has no user actor — for example a `CronTask`, other background processing, or any event whose actor defaults to canvas-bot — there is no browser to navigate and the redirect is silently ignored. See [Event Actor](/sdk/events/#event-actor) for which events carry an actor.
Provide **exactly one** destination:
  - `url` — a full URL string the plugin composes in Python (it may include patient/note ids). Either an external URL (`https://...`) or an internal Canvas path (`/panel`, `/patient/{key}?noteId=...`).
  - `application_id` — the identifier of a Canvas application to open.
By default the navigation replaces the current tab. Set `target` to `RedirectEffect.TargetType.NEW_TAB` to open a `url` destination in a new tab instead.
> **Internal navigation must be a root-relative path that starts with`/`** — e.g. `url="/schedule"` (or `/panel`, `/patient/{key}?noteId=...`). A leading-slash path is the _only_ form treated as internal navigation. A bare page name like `schedule` will **not** work: anything that doesn't start with `/` is treated as an external URL and is rejected unless it's a full `https://...` URL (protocol-relative `//...` and backslash `/\...` values are always rejected). The matching `REDIRECT_ALLOWLIST_INTERNAL` entries must likewise be leading-slash paths (e.g. `/schedule`).
##  Attributes 
Name| Type| Required| Description  
---|---|---|---  
`url`| `str`| Yes*| A full external URL (`https://...`) or an internal Canvas path that **must start with`/`** (e.g. `/schedule`, `/patient/{key}`), composed by the plugin. Non-empty.  
`application_id`| `str`| Yes*| The identifier of a Canvas application to open. Must exist and be enabled.  
`target`| `TargetType`| No| Where to open a `url` destination. Defaults to `TargetType.SAME_TAB`.  
***** Provide **exactly one** of `url` or `application_id` — they are mutually exclusive.
##  `TargetType`
A `StrEnum` of the supported navigation targets. You can also pass the string value.
Member| Value| Behavior  
---|---|---  
`RedirectEffect.TargetType.SAME_TAB`| `"same_tab"`| Replaces the current EHR view (full-page navigation). The default.  
`RedirectEffect.TargetType.NEW_TAB`| `"new_tab"`| Opens the destination in a new browser tab.  
##  Security & Allowlist 
Every destination is validated **on the server** before the browser navigates — the frontend is never trusted to decide whether a target is allowed. This blocks open-redirect abuse and accidental leakage of PHI through query parameters. **Targets are denied by default.**
The allowlist governs only _where a plugin may send a user_ — it does **not** change what that user is allowed to see, and cannot be used to bypass their permissions. A redirect performs an ordinary browser navigation, so the destination still enforces the user's own access: redirecting a user to a page or application they lack permission for behaves exactly as if they navigated there themselves (they're denied by that destination), and never elevates their access.
The allowlist is configured **per instance by an administrator** via three plugin secrets. Your plugin declares the keys in its manifest `variables`; the admin sets each value on the Plugin admin page, or from the CLI with [`canvas config set`](/sdk/canvas_cli/#canvas-config-set). (This redirect allowlist is separate from the manifest's `url_permissions` field, which allow-lists iframe and script domains for layout effects — the two are unrelated.) Each value is a list with **one entry per line** — entries are newline-delimited, not comma-separated, because URLs and paths can legitimately contain commas (e.g. `?q=1,2,3`):
Secret key| Value (one entry per line)| Permits  
---|---|---  
`REDIRECT_ALLOWLIST_INTERNAL`| `/patients`  
`/panel`  
`/patient`| those path roots and anything the plugin composes under them, matched at a path boundary (`/patient/{key}?noteId=...`).  
`REDIRECT_ALLOWLIST_EXTERNAL`| `https://app.example.com`| those origins/prefixes (**include the scheme**), matched **case-insensitively** at an origin/path boundary — so it does **not** match `https://app.example.com.evil.com`, and a differing port (e.g. `https://app.example.com:8443/...`) is not a match.  
`REDIRECT_ALLOWLIST_APPLICATION`| `my_plugin.applications.app:MyApp`| redirecting to those applications by id (matched exactly; the app must exist and be enabled).  
Declare the keys in your manifest so the admin can fill them:
    ```json
    {
      "variables": [
        { "name": "REDIRECT_ALLOWLIST_INTERNAL" },
        { "name": "REDIRECT_ALLOWLIST_EXTERNAL" },
        { "name": "REDIRECT_ALLOWLIST_APPLICATION" }
      ]
    }
    ```
Both steps are required, and both default to "blocked": if you don't **declare** a key in the manifest, the admin has no field to fill; if the admin doesn't **set** a value, that key's allowlist is empty. An empty or absent secret allows nothing — so each redirect category (internal / external / application) only works once its key is declared _and_ an admin has given it a value. A freshly installed plugin can therefore redirect nowhere until an admin opts it in.
Set a value from the CLI with your shell's newline quoting so each entry stays on its own line (see [`canvas config set`](/sdk/canvas_cli/#canvas-config-set)):
    ```console
    $ canvas config set my_plugin $'REDIRECT_ALLOWLIST_INTERNAL=/panel\n/patient'
    ```
Non-allowlisted destinations are dropped, and the platform logs only the plugin name and the blocked host (never the full URL/path). Protocol-relative (`//host`) and backslash (`/\host`) targets are always rejected.
##  Example Usage 
###  Redirect to a work queue after a note is signed 
Requires `/panel` in the plugin's `REDIRECT_ALLOWLIST_INTERNAL` secret.
    ```python
    from canvas_sdk.effects.redirect import RedirectEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.note import CurrentNoteStateEvent, NoteStates
    class RedirectAfterSign(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self):
            state = CurrentNoteStateEvent.objects.values_list("state", flat=True).get(
                id=self.event.target.id
            )
            if state != NoteStates.LOCKED:
                return []
            # Send the provider back to their work queue to grab the next patient.
            return [RedirectEffect(url="/panel").apply()]
    ```
###  Open an external URL in a new tab from an action button 
Requires `https://app.example.com` in the plugin's `REDIRECT_ALLOWLIST_EXTERNAL` secret.
    ```python
    return [
        RedirectEffect(
            url="https://app.example.com/orders/next",
            target=RedirectEffect.TargetType.NEW_TAB,
        ).apply()
    ]
    ```
###  Redirect to an application by id 
Requires the identifier in the plugin's `REDIRECT_ALLOWLIST_APPLICATION` secret.
    ```python
    return [RedirectEffect(application_id="my_plugin.applications.app:MyApp").apply()]
    ```
###  Redirect from an application iframe 
An application iframe can't return an effect directly. The clean pattern is to expose a [SimpleAPI](/sdk/handlers-simple-api/) endpoint on your plugin that returns a `RedirectEffect`, and have the iframe `fetch()` it. Because a SimpleAPI request is authenticated as the acting user, the returned effect is validated and delivered through the **exact same** interpreter → allowlist → per-user path as an action-button or note-sign redirect — there is no iframe-specific code path to reason about.
> **Why an API call and not`postMessage`?** An iframe could `postMessage` its parent window to request a redirect (the way the close-modal workflow does), but we recommend against it here. A redirect already has to make a server round-trip for allowlist validation, so routing the request through the parent window and a dedicated mutation would add a second mechanism that buys nothing. Having the iframe call your own API that returns the effect is cleaner:
> 
>   - **One mechanism, one mental model.** The iframe reuses the same effect pipeline as every other redirect — no separate frontend bridge, no dedicated mutation, and target validation lives in exactly one place (the interpreter).
>   - **Secure by construction.** The plugin whose allowlist is checked is _intrinsic_ : it's the plugin that owns the API endpoint. Nothing frontend-supplied has to be trusted or proven un-spoofable — a `postMessage` bridge would first have to attribute the message to an owning application before it could even pick which allowlist to apply.
>   - **Composable.** Your endpoint can do real work first — persist state, branch on the patient/note, decide _where_ to send the user — and then return the redirect alongside a normal JSON response.
> 
**The endpoint** returns the `RedirectEffect` (optionally with a response body for the `fetch`):
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.redirect import RedirectEffect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import SimpleAPI, StaffSessionAuthMixin, api
    class MyAppAPI(StaffSessionAuthMixin, SimpleAPI):
        @api.post("/redirect")
        def redirect(self) -> list[Response | Effect]:
            # ...optionally do work first (persist data, decide the destination)...
            return [
                RedirectEffect(url="/panel").apply(),  # or application_id="my_plugin.applications.app:MyApp"
                JSONResponse({"ok": True}),
            ]
    ```
**The iframe** calls it with a credentialed, same-origin request:
    ```js
    // inside the plugin application iframe
    fetch('/plugin-io/api/my_plugin/redirect', {
      method: 'POST',
      credentials: 'same-origin',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ destination: 'panel' })
    });
    ```
**How the redirect arrives.** The navigation does **not** come back in the `fetch()` response body. The effect is broadcast to the acting user and applied by the frontend's redirect subscription, exactly as for any other `RedirectEffect` — so the `fetch` response is just your endpoint's acknowledgement, and the browser navigates a moment later when the effect is delivered.
**Requirements & gotchas**
  - The endpoint must authenticate the request **as a specific Canvas user** — that user is the actor the redirect targets. Use [`StaffSessionAuthMixin`](/sdk/handlers-simple-api/) (as above) or `PatientSessionAuthMixin`, which resolve the acting user from the Canvas session, or another scheme that identifies a specific user (for example an OAuth token tied to a user). A **shared-secret** scheme — `BasicAuthMixin` or `APIKeyAuthMixin` — authenticates the _request_ but establishes no acting user, so a redirect returned from it has no browser to target and is silently dropped.
  - For the session mixins, the request must be **same-origin and credentialed** (`credentials: 'same-origin'`) so the session is sent and the server can identify the acting user. Plugin-served iframes — rendered from `LaunchModalEffect` content or a plugin-served URL — are same-origin. An **unauthenticated** request has no acting user either, so the redirect is silently dropped.
  - The target still has to be **allowlisted** (see Security & Allowlist); the API path enforces the identical gate.
  - `target` (new tab) applies only to `url` destinations; an `application_id` always opens in-app.
##  Validation 
Construction is validated by Pydantic and will raise a `ValidationError` for:
  - Providing neither `url` nor `application_id`, or providing both.
  - An empty `url`.
  - A `target` that is not a member of `TargetType`.
  - An `application_id` that does not resolve to an existing application.

# Reload Action Buttons Effect

Source: https://docs.canvasmedical.com/sdk/effect-reload-action-buttons/

The reload action button effects let a plugin tell Canvas to recompute and re-render its [action buttons](/sdk/handlers-action-buttons/) without the user reloading the page. This is useful after your plugin changes state that a button's `visible()` method, title, or color depends on, so the displayed buttons reflect the new state.
There are two effects, one for each scope:
  - `ReloadNoteActionButtonsEffect` — reloads the action buttons for a single note.
  - `ReloadPatientActionButtonsEffect` — reloads the action buttons for a patient.
Emit one from any handler's `compute()` or `handle()` — not only from an `ActionButton`. The effect re-fires the relevant [`SHOW_*_BUTTON`](/sdk/events/#action-buttons-events) events, so every button in that location recomputes `visible()` from scratch: the button set is rebuilt, not patched.
##  When to reload 
A button's `visible()` result, its title, and its color are all computed from live data each time the location is evaluated. Reloading is how you push those changes to the footer or header without a full page refresh. Common cases:
  - **The button has done its job.** Once a button is clicked and its action completes, it often no longer applies — reload so its `visible()` re-evaluates to `False` and the button drops out of the set instead of lingering as a stale, re-clickable control.
  - **The label or color should change.** When a button reflects state — a title that shows a count of outstanding items, or a color that turns green once a task is complete — reload after that state changes so the button re-renders with its new title and color.
  - **Data the button depends on changed elsewhere.** After a command is committed, a note transitions to a new state, or related records are updated by another handler, reload the location so every button recomputes against the current data.
* * *
##  ReloadNoteActionButtonsEffect 
Re-evaluates the note's action buttons in the `NOTE_HEADER`, `NOTE_FOOTER`, and `NOTE_HEADER_DROPDOWN` locations. It also re-reads the note's [footer configuration](/sdk/effect-note-footer-configuration/) (by re-firing `NOTE_FOOTER__GET_CONFIGURATION`), so a plugin that toggles `hide_default_state_buttons` can refresh whether Canvas's native footer buttons are hidden without a full page reload.
###  Attributes 
Field| Type| Description  
---|---|---  
`id`| `str \| UUID`| The external id of a [Note](/sdk/data-note/#note) (`Note.id`). The note must exist, or the effect raises a validation error.  
> **Warning:** The `note_id` carried by a [`SHOW_*_BUTTON`](/sdk/events/#action-buttons-events) context is the note's **database id** (`dbid`), while this effect is keyed by the note's **external id**. Resolve between them through the [`Note`](/sdk/data-note/#note) data model — for example `Note.objects.filter(dbid=...).first().id`.
###  Example 
This handler reloads a note's footer whenever any command is committed, so a button that hides while the note has uncommitted commands reappears the moment the last one is committed:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.action_button import ReloadNoteActionButtonsEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.command import Command
    class ReloadFooterOnCommandCommit(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(value)
            for value in EventType.values()
            if EventType.Name(value).endswith("_COMMAND__POST_COMMIT")
        ]
        def compute(self) -> list[Effect]:
            command = Command.objects.filter(id=self.event.target.id).first()
            if not command or not command.note:
                return []
            return [ReloadNoteActionButtonsEffect(id=str(command.note.id)).apply()]
    ```
##  ReloadPatientActionButtonsEffect 
Re-evaluates the patient's action buttons in the `CHART_PATIENT_HEADER` location.
###  Attributes 
Field| Type| Description  
---|---|---  
`id`| `str`| The id of a [Patient](/sdk/data-patient/#patient). The patient must exist, or the effect raises a validation error.  
###  Example 
This handler refreshes a patient's header buttons whenever one of their tasks changes, so a `CHART_PATIENT_HEADER` button that shows a live count of open tasks stays current as tasks are created or completed:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.action_button import ReloadPatientActionButtonsEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class ReloadPatientButtonsOnTaskChange(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.TASK_CREATED),
            EventType.Name(EventType.TASK_UPDATED),
        ]
        def compute(self) -> list[Effect]:
            patient_id = (self.event.context.get("patient") or {}).get("id")
            if not patient_id:
                return []
            return [ReloadPatientActionButtonsEffect(id=patient_id).apply()]
    ```

# Send Contact Verification

Source: https://docs.canvasmedical.com/sdk/effect-send-contact-verification/

The `SendContactVerification` effect instructs Canvas to send a verification (for example, an email or SMS code) to a specific Patient Contact Point. Use it to verify a patient's email address or phone number — for example, before relying on that channel for outbound communications, or before enabling patient-portal features that require a verified contact channel. It applies to any patient contact point; it isn't tied to the patient portal.
Attribute| Type| Description  
---|---|---  
`contact_point_id`| `str` or `UUID`| The id of the [`PatientContactPoint`](/sdk/effect-patient/#patientcontactpoint) to verify.  
##  Validation & Errors 
When an effect is prepared, the model validates inputs and returns structured error details if something is invalid.
  - **Contact Point Exists** — The effect verifies the provided `contact_point_id` maps to an existing `PatientContactPoint` record. If no matching record exists the effect will include an error detail with message: `Patient Contact Point does not exist`.
##  Caveats 
  - Emitting this effect will trigger a save to the associated `PatientContactPoint`. If your plugin sends `SendContactVerification` in direct response to a `PATIENT_CONTACT_POINT_UPDATED` event, the save triggered by the effect can cause the same event to fire again, producing an infinite event loop. To avoid this, debounce or detect origin (for example, ignore updates originating from the plugin runner or set a transient flag on the model) before emitting the effect in response to contact point update events.
##  Example Usage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.send_contact_verification import SendContactVerificationEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CONTACT_POINT_CREATED)
        def compute(self) -> list[Effect]:
            contact_point_id = self.event.target.id
            verification_effect = SendContactVerificationEffect(contact_point_id=contact_point_id)
            return [verification_effect.apply()]
    ```
##  Notes 
  - This effect only triggers a verification send for the contact point. It does not mark the contact as verified — verification completion is handled by the platform when the patient completes the challenge.
  - The effect relies on `PatientContactPoint` existing in the database. If your integration creates contact points in the same operation, ensure they are persisted before emitting this effect.

# Service Provider Effects

Source: https://docs.canvasmedical.com/sdk/effect-service-provider/

The Service Provider effects let a plugin build and maintain its own directory of external providers. Providers created this way are readable through the [ServiceProvider](/sdk/data-serviceprovider/) data model — where they are flagged with `is_customer_managed` — and can be offered in the provider-search surfaces by [handling those searches yourself](/guides/customize-search-results/#offering-your-own-providers-alongside-the-directory).
##  Create Service Provider 
Creates a service provider, or updates a matching one.
###  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`first_name`| `str`| Provider name, or the organization name| Yes  
`specialty`| `str`| Free text| Yes  
`business_address`| `str`| Business address| Yes  
`last_name`| `str` or `None`| Omit for organizations| No  
`practice_name`| `str` or `None`| Practice or organization name| No  
`business_phone`| `str` or `None`| Business phone number| No  
`business_fax`| `str` or `None`| Business fax number| No  
`npi`| `str` or `None`| Exactly 10 digits| No  
`direct_address`| `str` or `None`| Up to 512 characters| No  
`notes`| `str` or `None`| Free-text notes| No  
`is_active`| `bool`| Defaults to `True`| No  
The required fields reject empty strings.
###  Calling create more than once 
Creating never produces a duplicate. These four fields together identify a provider:
  - `first_name`
  - `last_name`
  - `specialty`
  - `business_address`
If a provider already exists with the same values for all four, the create updates that provider rather than adding a second one. Only a provider that differs on at least one of them is created as a new record.
When an existing provider is matched:
  - only the fields you sent are written; the rest keep their current values
  - a deactivated provider stays deactivated unless you send `is_active=True`
Because of this, the same create is safe to run repeatedly — on a schedule, on every plugin install, or as a re-import of a directory you already loaded. An omitted or empty `last_name` is treated as the empty string when matching, so repeated creates for an organization resolve to the same record.
###  Example Usage 
    ```python
    from canvas_sdk.effects.service_provider import ServiceProvider
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class ProviderLoader(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PLUGIN_CREATED)]
        def compute(self):
            return [
                ServiceProvider(
                    first_name="Jane",
                    last_name="Doe",
                    specialty="Cardiology",
                    business_address="123 Main St",
                    business_fax="5555550100",
                    npi="1234567890",
                    direct_address="jane.doe@direct.example.org",
                ).create(),
                # An organization has no last name.
                ServiceProvider(
                    first_name="Acme Imaging Center",
                    specialty="Radiology",
                    business_address="1 Hospital Way",
                ).create(),
            ]
    ```
##  Update Service Provider 
Updates the provider with the given `id`. Only the fields you set are sent, so an update never clears a field you did not mention. `first_name` and `specialty` cannot be set to `None`.
    ```python
    ServiceProvider(id="d2194110-5c9a-4842-8733-ef09ea5ead11", notes="Prefers fax").update()
    ```
###  Reactivating a provider 
Set `is_active=True` explicitly. Nothing else reactivates a provider.
    ```python
    ServiceProvider(id="d2194110-5c9a-4842-8733-ef09ea5ead11", is_active=True).update()
    ```
##  Deactivate Service Provider 
Deactivates a provider without deleting it, so anything referencing it keeps working.
    ```python
    ServiceProvider(id="d2194110-5c9a-4842-8733-ef09ea5ead11").deactivate()
    ```
##  Reading providers back 
Use the [ServiceProvider data module](/sdk/data-serviceprovider/), and `is_customer_managed` to read only the providers your plugin created:
    ```python
    from canvas_sdk.v1.data.service_provider import ServiceProvider
    ServiceProvider.objects.filter(is_customer_managed=True, is_active=True)
    ```
To surface them in the Refer, Imaging Order, fax recipient, or external care team searches, see [Offering your own providers alongside the directory](/guides/customize-search-results/#offering-your-own-providers-alongside-the-directory).
To offer them in a provider search, see [`as_search_result` and `as_search_contact`](/sdk/data-serviceprovider/#search-results).

# StaffExternalIdentifier

Source: https://docs.canvasmedical.com/sdk/effect-staff-external-identifier/

Manage external identifiers on a staff member from a plugin. `StaffExternalIdentifier` is a single effect class with three methods — `.create()`, `.update()`, and `.delete()` — and which fields are required depends on the operation.
##  Methods 
###  create() → Effect 
Creates a new external identifier on the specified staff member.
####  Attributes 
Attribute| Type| Required| Description  
---|---|---|---  
`staff_id`| `str` / `UUID`| Yes| UUID of the [Staff](/sdk/data-staff/) record.  
`value`| `str`| Yes| The identifier value (e.g. an employee ID).  
`system`| `str`| No| The system the identifier belongs to (typically a URL).  
####  Validation 
  - `staff_id` must reference an existing Staff record, or the effect raises a descriptive error.
  - `id` must not be set on `create()` — the UUID is assigned server-side. Supplying it fails validation.
  - `value` and `staff_id` are required.
####  Server-side defaults 
Canvas applies these defaults on `create()`:
  - `use` → `"usual"`
  - `issued_date` → `"1970-01-01"`
  - `expiration_date` → `"2100-12-31"`
####  Example 
    ```python
    from canvas_sdk.effects.staff import StaffExternalIdentifier
    effect = StaffExternalIdentifier(
        staff_id="4150cd20de8a470aa570a852859ac87e",
        system="https://hr.example.com/",
        value="EMP-001234",
    ).create()
    ```
###  update() → Effect 
Updates fields on an existing external identifier. Only the fields you set on the effect are written; unset fields keep their existing values.
####  Attributes 
Attribute| Type| Required| Description  
---|---|---|---  
`id`| `str` / `UUID`| Yes| UUID of the identifier to update.  
`value`| `str`| No| New identifier value. Only written if supplied.  
`system`| `str`| No| New system value. Only written if supplied.  
####  Validation 
  - `id` is required and must reference an existing StaffExternalIdentifier record, or the effect raises a descriptive error.
####  Example 
    ```python
    from canvas_sdk.effects.staff import StaffExternalIdentifier
    effect = StaffExternalIdentifier(
        id="00000000-0000-0000-0000-000000000001",
        value="EMP-005678",
    ).update()
    ```
###  delete() → Effect 
Deletes the external identifier identified by `id`.
####  Attributes 
Attribute| Type| Required| Description  
---|---|---|---  
`id`| `str` / `UUID`| Yes| UUID of the identifier to delete.  
####  Validation 
  - `id` is required and must reference an existing StaffExternalIdentifier record, or the effect raises a descriptive error.
####  Example 
    ```python
    from canvas_sdk.effects.staff import StaffExternalIdentifier
    effect = StaffExternalIdentifier(
        id="00000000-0000-0000-0000-000000000001",
    ).delete()
    ```

# StaffMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-staff-metadata/

The `StaffMetadata` effect provides a flexible key-value storage system for staff-specific data within the Canvas system, letting plugins attach extensible information beyond the standard staff data model.
##  Overview 
`StaffMetadata` exposes `.upsert(value)` to write or replace a metadata entry, and `.delete()` to remove one. The same key may be used across many staff members; the `(staff, key)` pair is unique per staff member.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`staff_id`| `str`| Id of the [Staff](/sdk/data-staff/) record to associate metadata with| Yes  
`key`| `str`| Unique identifier for the metadata entry within the staff context| Yes  
##  Methods 
###  upsert(value: str) → Effect 
Creates or updates a metadata entry for the specified staff and key combination.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`value`| `str`| The metadata value to store| Yes  
####  Behavior 
  - If a metadata entry with the specified key already exists for the staff member, it will be updated with the new value.
  - If no entry exists, a new metadata entry will be created.
  - Metadata entries are isolated per staff member — the same key can hold different values for different staff members.
  - Values are stored as strings with no schema enforcement; the plugin is responsible for validating its own values.
####  Key Naming Conventions 
  1. **Use descriptive names**. Choose keys that clearly indicate the purpose of the metadata.
     - Good: `department`, `cost_center`, `external_employee_id`
     - Avoid: `data1`, `temp`, `misc`
  2. **Namespace your keys**. Prefix keys for integrations or modules to avoid collisions.
     - Example: `hr.employee_id`, `payroll.cost_center`
####  Value Storage 
  1. **String serialization**. All values are stored as strings. For complex data:
         ```python
         import json
         from canvas_sdk.effects.staff_metadata import StaffMetadata
         metadata = StaffMetadata(
             staff_id="4150cd20de8a470aa570a852859ac87e",
             key="hr.profile",
         )
         complex_data = {"hire_date": "2020-01-15", "department": "cardiology"}
         metadata.upsert(json.dumps(complex_data))
         ```
  2. **Boolean values**. Store as `"true"` or `"false"` strings for consistency.
####  Examples 
    ```python
    from canvas_sdk.effects.staff_metadata import StaffMetadata
    # Tag a provider with their primary department
    metadata = StaffMetadata(
        staff_id="4150cd20de8a470aa570a852859ac87e",
        key="department",
    )
    effect = metadata.upsert("cardiology")
    ```
Mirroring an HR system from a handler:
    ```python
    from canvas_sdk.effects.staff_metadata import StaffMetadata
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    class StaffHRSync(BaseHandler):
        """Sync select fields from an HR webhook payload onto Canvas staff."""
        RESPONDS_TO = EventType.Name(EventType.STAFF_UPDATED)
        def compute(self):
            staff_id = self.event.context["staff"]["id"]
            hr_record = self.event.context.get("fields", {}).get("hr_record", {})
            return [
                StaffMetadata(staff_id=staff_id, key=f"hr.{key}").upsert(str(value))
                for key, value in hr_record.items()
            ]
    ```
###  delete() → Effect 
Removes the metadata entry identified by `(staff_id, key)`.
####  Behavior 
  - Removes the row that matches both `staff_id` and `key`. Returns success even if no row was present (idempotent).
  - Does not affect other metadata entries for the same staff member with different keys.
####  Example 
    ```python
    from canvas_sdk.effects.staff_metadata import StaffMetadata
    # Clear the department tag for a staff member
    effect = StaffMetadata(
        staff_id="4150cd20de8a470aa570a852859ac87e",
        key="department",
    ).delete()
    ```
##  Validation 
The effect validates before execution:
  - **Staff existence** : the `staff_id` must correspond to an existing Staff record, or the effect raises a descriptive error.
  - **Required fields** : `staff_id` and `key` must be non-empty strings, and `.upsert(...)` requires a `value`.

# Surescripts Effects

Source: https://docs.canvasmedical.com/sdk/effect-surescripts/

> **Warning:** **This feature must be enabled by Canvas.** To use the Surescripts effects, [contact Canvas Support](https://portal.usepylon.com/canvas-medical/forms/standard) to have these Surescripts effects enabled for your instance. Until it is enabled, these effects will not send requests.
Surescripts effects let plugins query insurance eligibility, benefits, and medication history through Surescripts. Eligibility and benefits requests receive responses asynchronously as corresponding events; medication history is handled by Canvas without a plugin-facing response.
##  Eligibility 
Check a patient's insurance coverage and plan details. Send a request with `SendSurescriptsEligibilityRequestEffect`, then handle the `SURESCRIPTS_ELIGIBILITY_RESPONSE` event when the response arrives.
###  SendSurescriptsEligibilityRequestEffect 
Sends an eligibility request to Surescripts to check a patient's insurance coverage. The response arrives as a `SURESCRIPTS_ELIGIBILITY_RESPONSE` event.
####  Attributes 
Name| Type| Description  
---|---|---  
`patient_id`| `str`| The Canvas [Patient](/sdk/data-patient/#patient) ID for whom to check eligibility.  
`staff_id`| `str`| The Canvas [Staff](/sdk/data-staff/#staff) ID initiating the request.  
`correlation_id`| `str`| A unique identifier for matching the response to this request. Auto-generated if not provided. Read this value after instantiation and store it for later use.  
####  Correlation ID 
Each eligibility request includes a `correlation_id` that echoes back in the corresponding `SURESCRIPTS_ELIGIBILITY_RESPONSE` event. Use this to match responses to their originating requests when handling multiple concurrent eligibility checks.
By default, the effect auto-generates a unique `correlation_id` (a UUID hex string). You can pass your own value if you need to thread external state through the request-response cycle.
> **Note:** The `correlation_id` is required for receiving response events. The platform only delivers `SURESCRIPTS_ELIGIBILITY_RESPONSE` events to plugins that sent a request with a valid `correlation_id`.
####  Example Usage 
    ```python
    from canvas_sdk.effects.surescripts.surescripts_messages import SendSurescriptsEligibilityRequestEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class CheckEligibilityOnAppointment(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.APPOINTMENT_CREATED)]
        def compute(self):
            patient_id = self.event.target.get("id")
            staff_id = self.event.context.get("created_by", {}).get("id")
            effect = SendSurescriptsEligibilityRequestEffect(
                patient_id=patient_id,
                staff_id=staff_id,
            )
            # Store the correlation_id to match the response later
            # For example, save it to custom data or cache
            correlation_id = effect.correlation_id
            return [effect.apply()]
    ```
###  Handling Eligibility Responses 
When Surescripts returns an eligibility response, the platform fires a `SURESCRIPTS_ELIGIBILITY_RESPONSE` event. Use the typed data classes from `canvas_sdk.events.surescripts` to parse the response.
> **Important:** To prevent infinite loops, you cannot return a `SendSurescriptsEligibilityRequestEffect` from a handler that responds to `SURESCRIPTS_ELIGIBILITY_RESPONSE` events.

            response = SurescriptsEligibilityResponse.from_context(self.event.context)
            log.info(f"Received eligibility response for correlation_id: {response.correlation_id}")
            log.info(f"Patient ID: {response.patient_id}")
            if response.error:
                log.error(f"Eligibility check failed: {response.error}")
                return []
            for plan in response.plans:
                if plan.rejected:
                    log.warning(f"Plan rejected: {plan.pbm_name} - {plan.reject_reason}")
                else:
                    log.info(f"Active plan: {plan.pbm_name}, Member ID: {plan.member_id}")
                    if plan.service_types:
                        log.info(f"  Service types: {', '.join(plan.service_types)}")
            return []
    ```
##  Benefits

`correlation_id`| `str`| A unique identifier for matching the response to this request. Auto-generated if not provided. Read this value after instantiation and store it for later use.  
####  Correlation ID 
As with eligibility requests, each benefits request includes a `correlation_id` that echoes back in the corresponding `SURESCRIPTS_BENEFITS_RESPONSE` event. Use this to match responses to their originating requests when handling multiple concurrent benefits checks.
By default, the effect auto-generates a unique `correlation_id` (a UUID hex string). You can pass your own value if you need to thread external state through the request-response cycle.
> **Note:** The `correlation_id` is required for receiving response events. The platform only delivers `SURESCRIPTS_BENEFITS_RESPONSE` events to plugins that sent a request with a valid `correlation_id`.
####  Example Usage 
    ```python
    from canvas_sdk.effects.surescripts.surescripts_messages import SendSurescriptsBenefitsRequestEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class CheckBenefitsOnPrescription(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PRESCRIBE_COMMAND__POST_ORIGINATE)]
        def compute(self):
            patient_id = self.event.target.get("id")
            staff_id = self.event.context.get("created_by", {}).get("id")
            effect = SendSurescriptsBenefitsRequestEffect(
                patient_id=patient_id,
                staff_id=staff_id,
                medication_description="Lipitor 10 mg tablet",
                medication_ndc="00071015523",
                plan="Acme PBM",
            )
            # Store the correlation_id to match the response later
            correlation_id = effect.correlation_id
            return [effect.apply()]
    ```
###  Handling Benefits Responses 
When Surescripts returns a benefits response, the platform fires a `SURESCRIPTS_BENEFITS_RESPONSE` event. Use the typed data classes from `canvas_sdk.events.surescripts` to parse the response.
> **Important:** To prevent infinite loops, you cannot return a `SendSurescriptsBenefitsRequestEffect` from a handler that responds to `SURESCRIPTS_BENEFITS_RESPONSE` events.

####  Response Handler Example 
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.events.surescripts import (
        BenefitCoverage,
        SurescriptsBenefitsResponse,
        TherapeuticAlternative,
    )
    from canvas_sdk.handlers.base import BaseHandler
    from logger import log
    class HandleBenefitsResponse(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.SURESCRIPTS_BENEFITS_RESPONSE)]
        def compute(self):
            # Parse the event context into a typed response object
            response = SurescriptsBenefitsResponse.from_context(self.event.context)
            log.info(f"Received benefits response for correlation_id: {response.correlation_id}")
            log.info(f"Medication NDC: {response.medication_ndc}")
            if response.error:
                log.error(f"Benefits check failed: {response.error}")
                return []
            for coverage in response.coverages:
                if coverage.rejected:
                    log.warning(f"Coverage rejected: {coverage.pbm_name} - {coverage.reject_reason}")
                    continue
                log.info(f"{coverage.pbm_name} formulary status: {coverage.formulary_status}")
                if coverage.prior_authorization_required:
                    log.info("  Prior authorization required")
                for copay in coverage.copays:
                    log.info(f"  Copay: {copay}")
                for alternative in coverage.alternatives:
                    log.info(f"  Alternative: {alternative.description} ({alternative.ndc})")
            return []
    ```
##  Medication History 
Request a patient's medication history from Surescripts.
Unlike eligibility and benefits, this effect has **no paired response event** — Canvas retrieves the medication history and processes it on the platform side; the results are not delivered back to your plugin. There is no `correlation_id` and no `SURESCRIPTS_MEDICATION_HISTORY_RESPONSE` event to handle.
###  SendSurescriptsMedicationHistoryRequestEffect 
Sends a medication history request to Surescripts for the patient. Canvas requests the patient's recent fill history (currently the trailing 12 months).
####  Attributes 
Name| Type| Description  
---|---|---  
`patient_id`| `str`| The Canvas [Patient](/sdk/data-patient/#patient) ID whose medication history to request.  
`staff_id`| `str`| The Canvas [Staff](/sdk/data-staff/#staff) ID initiating the request.  
####  Example Usage 
    ```python
    from canvas_sdk.effects.surescripts.surescripts_messages import SendSurescriptsMedicationHistoryRequestEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class RequestMedicationHistoryOnAppointment(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.APPOINTMENT_CREATED)]
        def compute(self):
            patient_id = self.event.target.get("id")
            staff_id = self.event.context.get("created_by", {}).get("id")
            return [

# TaskMetadata Effect

Source: https://docs.canvasmedical.com/sdk/effect-task-metadata/

The `TaskMetadata` effect provides a flexible key-value storage system for task-specific data within the Canvas system. This effect enables the creation and updating of custom metadata entries associated with task records, allowing for extensible task information storage beyond standard task fields.
##  Overview 
Task metadata serves as a powerful extension mechanism for storing custom task-related information that doesn't fit within the standard task data model.
##  Attributes 
Attribute| Type| Description| Required  
---|---|---|---  
`task_id`| `str`| Id of the task record to associate metadata with| Yes  
`key`| `str`| Unique identifier for the metadata entry within the task context| Yes  
##  Methods 
###  upsert(value: str) → Effect 
Creates or updates a metadata entry for the specified task and key combination.
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`value`| `str`| The metadata value to store| Yes  
####  Returns 
An `Effect` object configured for upserting task metadata.
####  Behavior 
  - If a metadata entry with the specified key already exists for the task, it will be updated with the new value
  - If no entry exists, a new metadata entry will be created
  - The operation is idempotent - repeated calls with the same key and value will not create duplicate entries
##  Implementation Details 
###  Validation 
The effect performs comprehensive validation before execution:
  1. **Task Existence Validation** : Verifies that the referenced task exists in the system
  - Queries the task database to confirm the `task_id` corresponds to an existing task record
  - Returns a descriptive error if the task is not found
  1. **Field Validation** : Ensures all required fields are provided and properly formatted
  - Both `task_id` and `key` must be non-empty strings
  - The `value` parameter in the `upsert` method must be provided
###  Data Structure 
The effect payload is structured as JSON with the following schema:
    ```json
    {
      "data": {
        "task_id": "task-id",
        "key": "metadata-key",
        "value": "metadata-value"
      }
    }
    ```
##  Example Usage 
###  Basic Usage 
    ```python
    from canvas_sdk.effects.task import TaskMetadata
    # Create a metadata entry for task tracking
    metadata = TaskMetadata(
        task_id="550e8400e29b41d4a716446655440000",
        key="external_system_id"
    )
    # Upsert the metadata value
    effect = metadata.upsert("EXT-12345")
    ```
###  Task Integration Example 
    ```python
    import json
    from canvas_sdk.effects.task import TaskMetadata
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.events import EventType
    class TaskMetadataHandler(BaseHandler):
      """
      Adds metadata to tasks based on task properties.
      """
      RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
      def compute(self):
        task_id = self.context["task"]["id"]
        task_labels = self.context.get("task", {}).get("labels", [])
        effects = []
        # Store task creation source
        metadata = TaskMetadata(
          task_id=task_id,
          key="creation_source"
        )
        effects.append(metadata.upsert("protocol"))
        # Store label information as JSON
        if task_labels:
          labels_metadata = TaskMetadata(
            task_id=task_id,
            key="original_labels"
          )
          effects.append(labels_metadata.upsert(json.dumps(task_labels)))
        return effects
    ```
##  Best Practices 
###  Key Naming Conventions 
  1. **Use Descriptive Names** : Choose keys that clearly indicate the purpose of the metadata
  - Good: `external_system_id`, `workflow_stage`, `integration_source`
  - Avoid: `data1`, `temp`, `misc`
  1. **Namespace Your Keys** : When building integrations or modules, prefix keys to avoid collisions
  - Example: `integration_task_id`, `workflow_current_stage`, `automation_trigger_id`
###  Value Storage 
  1. **String Serialization** : All values are stored as strings. For complex data types:
         ```python
         # Storing JSON data
         import json
         from canvas_sdk.effects.task import TaskMetadata
         metadata = TaskMetadata(
             task_id="550e8400e29b41d4a716446655440000",
             key="workflow_state"
         )
         complex_data = {"stage": "review", "approvers": ["user1", "user2"], "timestamp": "2025-01-15T10:30:00Z"}
         metadata.upsert(json.dumps(complex_data))
         ```
  2. **Boolean Values** : Store as "true" or "false" strings for consistency
         ```python
         from canvas_sdk.effects.task import TaskMetadata
         needs_followup = True
         metadata = TaskMetadata(
             task_id="550e8400e29b41d4a716446655440000",
             key="requires_followup"
         )
         metadata.upsert("true" if needs_followup else "false")
         ```
##  Notes 
  - Metadata entries are task-specific and isolated - the same key can have different values for different tasks
  - There is no built-in versioning; updating a key overwrites the previous value
  - The system does not enforce any schema on metadata values - validation is the responsibility of the implementing code

An example of adding a task:
    ```python
    import arrow
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.task import AddTask, AddTaskComment, UpdateTask, TaskPriority, TaskStatus
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data.lab import LabReport
    from canvas_sdk.v1.data.staff import Staff
    from canvas_sdk.v1.data.team import Team
    from canvas_sdk.v1.data.referral import Referral
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.LAB_REPORT_CREATED),
        ]
        def compute(self) -> list[Effect]:
            lab_report = LabReport.objects.get(id=self.target)
            staff_assignee = Staff.objects.get(last_name="Weed")
            team = Team.objects.get(name="Labs")
            linked_task_type = AddTask.LinkableObjectType.REFERRAL
            referral = Referral.objects.get(id="d2194110-5c9a-4842-8733-ef09ea5ead11")
            if lab_report.patient:
                add_task = AddTask(
                    assignee_id=staff_assignee.id,
                    author_id=staff_assignee.id,
                    team_id = team.id,
                    patient_id=lab_report.patient.id,
                    title="Please call the patient with their test results.",
                    due=arrow.utcnow().shift(days=5).datetime,
                    status=TaskStatus.OPEN,
                    priority=TaskPriority.URGENT,
                    labels=["call"],
                    linked_object_id=referral.id,
                    linked_object_type=linked_task_type,
                )
                return [add_task.apply()]
            return []
    ```
##  Updating a Task 
To update an existing task, import the `UpdateTask` class and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
id| required| string| The id of the task being updated.  
assignee_id| optional| string| The id of the [staff](/sdk/data-staff/) the task should be assigned to.  
team_id| optional| string| The id of the [team](/sdk/data-team/) the task should be assigned to.  
patient_id| optional| string| The id of the [patient](/sdk/data-patient/) the task is associated with.  
title| optional| string| The title of the task. This is displayed at the top of a task card in the Canvas UI.  
due| optional| datetime| A date/time when the task is due.  
status| optional| TaskStatus| A status of `OPEN`, `CLOSED` or `COMPLETED`. Defaults to `OPEN` if not supplied.  
priority| optional| TaskPriority| A priority of `STAT`, `URGENT`, or `ROUTINE`. See TaskPriority.  
labels| optional| list[string]| A list of labels that will be added at the bottom of a task card in the Canvas UI.  
An example of updating a task to a status of `COMPLETED`:
    ```python
    from canvas_sdk.effects.task import UpdateTask, TaskStatus
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        def compute(self):
            update_task = UpdateTask(
                id="d06276ba-85c5-471b-87c0-9c9805f4ca6f",
                status=TaskStatus.COMPLETED,
            )
            return [update_task.apply()]
    ```
##  Adding a comment to a task 
To add a comment to a task, import the `AddTaskComment` class and create an instance of it.
Attribute|  | Type| Description  
---|---|---|---  
task_id| required| string| The id of the task being updated.  
body| required| string| The comment body.  
author_id| optional| string or UUID| Author's id to set task comment creator, defaults to CanvasBot.  
    ```python
    from canvas_sdk.effects.task import AddTaskComment
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.staff import Staff
    class MyHandler(BaseHandler):
        def compute(self):
            author = Staff.objects.get(last_name="Weed")
            add_task_comment = AddTaskComment(
                task_id="d06276ba-85c5-471b-87c0-9c9805f4ca6f",
                body="I tried to call the patient but did not get an answer.",
                author_id=author.id
            )
            return [add_task_comment.apply()]
    ```
##  Creating a task and a comment together 
`AddTaskComment` requires the `task_id` of an existing task. To create a brand new task **and** add a comment to it in a single `compute()` return, supply your own `id` to `AddTask` and reuse that same value as the `task_id` on `AddTaskComment`. Because the `id` on `AddTask` is optional and is generated for you when omitted, the trick is simply to generate it yourself so you can reference it on the comment.
There is no need to create the task first and listen for a follow-up event — just return both effects from the same handler, with the `AddTask` effect before the `AddTaskComment` effect.
    ```python
    import uuid
    import arrow
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.task import AddTask, AddTaskComment, TaskStatus
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.LAB_REPORT_CREATED),
        ]
        def compute(self) -> list[Effect]:
            # Generate the task id up front so the comment can reference it.
            task_id = str(uuid.uuid4())
            add_task = AddTask(
                id=task_id,
                title="Please call the patient with their test results.",
                due=arrow.utcnow().shift(days=1).datetime,
                status=TaskStatus.OPEN,
            )
            add_task_comment = AddTaskComment(
                task_id=task_id,
                body="Results flagged abnormal — follow up today.",
            )
            # Order matters: the task must be created before the comment.
            return [add_task.apply(), add_task_comment.apply()]
    ```
> **Note:** The effects are applied in the order they are returned, so the `AddTask` effect must come before the `AddTaskComment` effect that references it. Both effects must be returned from the same handler — don't split them across separate handlers or plugins, and don't defer either effect, since that breaks the ordering the comment relies on.

# Effects

Source: https://docs.canvasmedical.com/sdk/effects/

Effects are instructions that plugins can return in order to perform an action in the Canvas EMR. This makes it possible to define workflows that create commands, show notifications, modify search results, etc.
Effects have a `type` and a `payload`. The `type` determines the action that will be performed with the data provided in the `payload`.
##  Using Effects 
###  Basic Usage 
Effects are returned as a list from the `compute` method of a plugin that inherits from `BaseHandler`. For example:
    ```python
    import json
    from canvas_sdk.events import EventType
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.handlers.base import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.MEDICATION_STATEMENT__MEDICATION__POST_SEARCH)
        def compute(self):
            results = self.context.get("results")
            post_processed_results = []
            ## custom results-modifying code here
            ...
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(post_processed_results),
                )
            ]
    ```
In the above example, the `Effect` object is constructed manually, with the `type` and `payload` set directly.
Some effects have helper classes that assist you by providing payload validation and constructing the effect object for you. The example below shows the [`PatientChartSummaryConfiguration`](/sdk/layout-effect/#patient-summary) class in use:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.effects.patient_chart_summary_configuration import PatientChartSummaryConfiguration
    class CustomChartLayout(BaseHandler):
        """
        This event handler rearranges the patient summary section and hides those
        not used by the installation's organization.
        """
        # This event fires when a patient's chart summary section is loading.
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)
        def compute(self):
            layout = PatientChartSummaryConfiguration(sections=[
              PatientChartSummaryConfiguration.Section.SOCIAL_DETERMINANTS,
              PatientChartSummaryConfiguration.Section.ALLERGIES,
              PatientChartSummaryConfiguration.Section.VITALS,
              PatientChartSummaryConfiguration.Section.MEDICATIONS,
              PatientChartSummaryConfiguration.Section.CONDITIONS,
              PatientChartSummaryConfiguration.Section.IMMUNIZATIONS,
            ])
            return [layout.apply()]
    ```
###  Async Execution 
By default, effects returned from a plugin's `compute` method are executed inline as part of the request that triggered them. Any `Effect` can be opted into asynchronous execution by chaining `.set_async()` on it, in which case the platform will run the effect as an asynchronous task instead of inline. This is useful for effects that should run on a delay, that are tolerant of retries, or that you don't want to block the originating request.
    ```python
    from canvas_sdk.effects.claim import ClaimEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self):
            claim_id = self.event.context["claim_id"]
            return [
                ClaimEffect(claim_id=claim_id)
                .add_comment("Reviewed by automation.")
                .set_async(delay_seconds=60, max_retries=3)
            ]
    ```
`set_async()` returns the same `Effect` so it can be chained directly off any effect-producing call (e.g. `ClaimEffect(...).add_comment(...)`, `Response(...).apply()`, or a manually-constructed `Effect(...)`).
####  Parameters 
Parameter| Type| Description| Required  
---|---|---|---  
`delay_seconds`| `int`| Number of seconds to wait before running the effect. Must be non-negative. `0` schedules the effect to run asynchronously as soon as possible.| No  
`max_retries`| `int`| Maximum number of retry attempts on failure. Must be non-negative. When omitted, the platform default is applied. Pass `0` to explicitly disable retries.| No  
Both parameters are keyword-only. Calling `.set_async()` with neither argument is a no-op and returns the effect unchanged.
####  Implementation Details 
  - Negative values or non-integer values for `delay_seconds` or `max_retries` raise `TypeError` / `ValueError`.
###  Disallowed Effect/Event Combinations 
Canvas prevents certain combinations of events and effects to avoid infinite loops that could occur when an effect triggers the same event that generated it. The following combinations are specifically disallowed:
Event Type| Disallowed Effect Types  
---|---  
`PATIENT_CHART__CONDITIONS`| `ADD_BANNER_ALERT`  
`ADD_OR_UPDATE_PROTOCOL_CARD`  
`PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION`| `ADD_BANNER_ALERT`  
`ADD_OR_UPDATE_PROTOCOL_CARD`  
For example, if you have a plugin that responds to `PATIENT_CHART__CONDITIONS` events, you cannot return `ADD_BANNER_ALERT` or `ADD_OR_UPDATE_PROTOCOL_CARD` effects from that plugin, as this could create an infinite loop where the effect triggers another conditions event.

# Events

Source: https://docs.canvasmedical.com/sdk/events/

**What is an Event?**
An event is an occurrence of an action that happens within Canvas. For example, a patient being prescribed a medication, a user searching for a condition or an appointment being created are all examples of events.
**Why should I use them?**
By writing plugins that respond to events, plugin code is notified and can react to events that occur in Canvas. This enables plugin authors to create custom workflows whenever a relevant event takes place, such as making a POST request to a webhook.
**How do I use them?**
To make plugin code react to an event, you can add the event types listed below into the `RESPONDS_TO` list of a plugin that inherits from `BaseHandler`. For example:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.ALLERGY_INTOLERANCE_CREATED)]
        def compute(self):
            ...
    ```
The plugin author can enter custom workflow code into the `compute` method that will execute every time an Allergy Intolerance is created in Canvas.
For more information on writing plugins, see the guide [here](/guides/your-first-plugin/).
##  Event Actor 
The actor is the user that initiated the event. It can be accessed within the compute method of the plugin by `self.event.actor`. For side-effect events or automated events where the action cannot be attributed to a specific user, the actor may be absent.
The actor is available in the following contexts:
  - [**SimpleAPI**](/sdk/handlers-simple-api/) handlers — HTTP and WebSocket requests
  - [**Action button**](/sdk/handlers-action-buttons/) handlers — button display and click events
  - [**Application**](/sdk/handlers-applications/) handlers
  - **Note state change events** — `NOTE_STATE_CHANGE_EVENT_PRE_CREATE`, `NOTE_STATE_CHANGE_EVENT_CREATED`, `NOTE_STATE_CHANGE_EVENT_UPDATED`
  - **Note UI events** — `NOTE_OPENED`, `NOTE_CLOSED`
  - **Note restrictions events** — `GET_NOTE_RESTRICTIONS`
  - **Note footer events** — `NOTE_FOOTER__GET_CONFIGURATION`
  - **Appointment scheduling events** — all `APPOINTMENT__*` events
  - **Patient chart and profile events** — all `PATIENT_CHART__*` events (conditions, medications, detected issues, etc.), chart summary configuration, panel sections, and patient metadata

    ```
##  Event Types and Context 
The event `target` object can be accessed within the compute method of the plugin by `self.event.target`. If `self.event.target.type` exists, it provides the same type that would be imported from the Data module. For example, a type of `Condition` would be the same as what you can import from `canvas_sdk.v1.data.condition`.
The event `context` object can be accessed via `self.event.context`. The content present in each event's context depends on the event type. The table below shows what you can expect for each event type, or you could take a look yourself by logging it out.
###  Common Context Patterns 
Many events include common contextual information to help you understand the scope and origin of the event:
  - **Patient context** : Most patient-related events include `"patient": {"id": pt_id}` in the context, allowing you to identify which patient the event relates to.
  - **Note context** : Command lifecycle events (PRE_COMMIT, POST_COMMIT, etc.) include `"note": {"uuid": note_id}` in the context, indicating the note where the command was executed.
  - **User context** : All command-related PRE_SEARCH and POST_SEARCH events include `"user": {"staff": staff_key}` in the context, containing the staff key of the user performing the search. This allows you to customize search results based on user-specific preferences, roles, or permissions.
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    class MyHandler(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.ALLERGY_INTOLERANCE_CREATED)]
        def compute(self):
            log.info(self.event.context)
            return []
    ```

####  Document Review Delegation 
The `DOCUMENT_DELEGATED` event fires when an uncategorized clinical document's review is delegated to another staff member or team, or routed back to its owner. It is a review-workflow event, separate from the Data Integration document-lifecycle events above.
DOCUMENT_DELEGATED  
---  
Occurs when an uncategorized clinical document review is delegated to another staff member or team from the document review surface, or routed back to its owner. This is distinct from DOCUMENT_REVIEWER_ASSIGNED, which fires only for Data Integration reviewer changes. `signature_consent` indicates whether the recipient may apply the owner's signature; `routed_back` is true when the document was returned to its owner; `comment` carries the delegator's instructions.

####  Eligibility responses 
A `COVERAGE_ELIGIBILITY_RESPONSE_CREATED` or `COVERAGE_ELIGIBILITY_RESPONSE_UPDATED` event fires on every eligibility response save. When the response resolves to a definite status, a matching `COVERAGE_ELIGIBILITY_RESPONSE_ACTIVE`, `COVERAGE_ELIGIBILITY_RESPONSE_INACTIVE`, or `COVERAGE_ELIGIBILITY_RESPONSE_FAILED` event fires alongside it. For example, when a failed eligibility check is first recorded, both `COVERAGE_ELIGIBILITY_RESPONSE_CREATED` and `COVERAGE_ELIGIBILITY_RESPONSE_FAILED` fire. Each event's context carries the derived `status` string and the associated `coverage`; `_FAILED` events also include the payer `errors`.

####  Surescripts 
Surescripts response events fire when the platform receives a response from Surescripts after a corresponding request effect is executed. These events let plugins react to insurance eligibility checks and other Surescripts services.
SURESCRIPTS_ELIGIBILITY_RESPONSE  
---  
Occurs when Surescripts returns an eligibility response after a `SendSurescriptsEligibilityRequestEffect` is executed. The response contains the patient's insurance plan information and coverage details. See [Handling Eligibility Responses](/sdk/effect-surescripts/#handling-eligibility-responses) for the typed response data classes and an example handler.

SURESCRIPTS_BENEFITS_RESPONSE  
---  
Occurs when Surescripts returns a benefits response after a `SendSurescriptsBenefitsRequestEffect` is executed. The response contains formulary and coverage details for the requested medication, including copays, quantity limits, and therapeutic alternatives. See [Handling Benefits Responses](/sdk/effect-surescripts/#handling-benefits-responses) for the typed response data classes and an example handler.

Target object| Context object  
    "id": message_id
    "type": [Message](/sdk/data-message/#message)
| 
    "patient":
       "id": pt_id  
MESSAGE_TRANSMISSION_CREATED  
---  
Occurs when a message transmission record is created. Message transmissions track delivery attempts and status for messages sent through various channels (SMS, email, etc.).  
Target object| Context object  
    "id": message_transmission_id
    "type": [MessageTransmission](/sdk/data-message/#messagetransmission)

####  Notes 
NOTE_STATE_CHANGE_EVENT_CREATED  
---  
Occurs as a note traverses through its state machine. This event can be used when looking at any changes to the [note state](/sdk/data-note/#notestates), including locking and unlocking.  
Target object| Context object  
    "id": nsce_id
    "type": NoteStateChangeEvent
| 
    "note_id": note_id,
    "patient_id": pt_id,
    "state": [str](/sdk/data-note/#notestates)  
NOTE_STATE_CHANGE_EVENT_PRE_CREATE  
---  
Occurs **before** a note state change event is created. This event allows protocols to perform validation and block the note state change if needed. If an [`EventValidationError`](/sdk/effect-event-validation-error) effect is returned, the note state change event is aborted and the error message is surfaced to the user.  
Target object| Context object  
    "id": nsce_id

| 
    "note_id": note_id,
    "patient_id": pt_id,
    "state": [str](/sdk/data-note/#notestates)  
NOTE_STATE_CHANGE_EVENT_UPDATED  
---  
Occurs if a note state change event is updated. Locking and unlocking both trigger an update event, and there is an *additional* update event when an archived PDF copy of the note finishes generating; this is done asynchronously.  
Target object| Context object  
    "id": nsce_id

    "user": {
      "type": str,
      "id": user_id
    }  
NOTE_SUPERVISING_PROVIDER_CHANGED  
---  
Occurs when a note's supervising provider is changed. The context includes the previous supervising provider's Staff ID, or `null` if the note previously had no supervising provider.  
Target object| Context object  
    "id": note_id
    "type": [Note](/sdk/data-note/)
| 
    "previous": null | {
      "id": staff_key
    }  
GET_NOTE_RESTRICTIONS  
---  
Fires every time a note is opened or its restrictions are refetched. Plugins respond with a [`NoteRestrictionsEffect`](/sdk/effect-note-restrictions/) to control whether the user can edit the note, whether the content is blurred, and what banner message is displayed. If no plugin responds, the note is unrestricted by default.

###  Command lifecycle events 
These events fire during the command lifecycle.
####  Generic events 
Event| Occurs when| PRE_COMMAND_ORIGINATE| Before any command is entered into a note.  
---|---  
POST_COMMAND_ORIGINATE| After any command is entered into a note.  
PRE_COMMAND_UPDATE| Before the data in any command is updated.  
POST_COMMAND_UPDATE| After the data in any command is updated.  
PRE_COMMAND_COMMIT| Before any command is committed.  
POST_COMMAND_COMMIT| After any command is committed.  
PRE_COMMAND_DELETE| Before any command is deleted.  
POST_COMMAND_DELETE| After any command is deleted.  
PRE_COMMAND_ENTER_IN_ERROR| Before any command is marked as entered in error.  
POST_COMMAND_ENTER_IN_ERROR| After any command is marked as entered in error.  
PRE_COMMAND_EXECUTE_ACTION| Before an action is executed on any command.  
POST_COMMAND_EXECUTE_ACTION| After an action is executed on any command.  
POST_COMMAND_INSERTED_INTO_NOTE| After a command is added to a note in the UI.  
AVAILABLE_ACTIONS| When a command is rendered in the UI, after any update to data, state, or other changes  
#####  Transaction Behavior 
Pre-event handlers (`PRE_COMMAND_ORIGINATE`, `PRE_COMMAND_COMMIT`, `PRE_COMMAND_UPDATE`) run synchronously inside the same database transaction as the command operation. Your handler can perform validation or modify data, and if it raises an exception, both your changes and the command operation roll back together.
Post-event handlers (`POST_COMMAND_ORIGINATE`, `POST_COMMAND_COMMIT`, `POST_COMMAND_UPDATE`) use Django's `on_commit` mechanism and execute only after the outermost transaction commits successfully. If you wrap a command operation inside a `transaction.atomic()` block, the post-event handlers won't fire until that outer transaction commits.
This model lets you combine command operations with other database writes in a single atomic unit. You can originate a command and update related records together, knowing that either all operations succeed or none do.
See [Transactions](/sdk/custom-data-transactions/) for more on using `transaction.atomic()` in your plugins.
#####  Context Overview 
Each command lifecycle event provides specific context to the handler, depending on the stage of the command lifecycle.
**Base Context (All Events Except`PRE_COMMAND_ORIGINATE`)**:
    ```json
    {
      "note": { "uuid": "note-123" },
      "patient": { "id": "patient-123" },
      "fields": { "key": "value" }
    }
    ```
  - `note.uuid`: The unique identifier of the note associated with the command.
  - `patient.id`: The unique identifier of the patient associated with the note.
  - `fields`: A dictionary containing command-specific details. See examples for each command.
**`PRE_COMMAND_ORIGINATE` Context**: Since the command is not yet connected to a note, the `PRE_COMMAND_ORIGINATE` event context only includes:
    ```json
    {
      "fields": { "key": "value" }
    }
    ```
  - `fields`: Contains details specific to the command being originated.

Fires from Canvas right before a lab order's FHIR `RequestGroup` is built and POSTed to Health Gorilla. Plugins may respond with one or more [HealthGorillaLabOrderOverride](/sdk/effect-health-gorilla-lab-order-override/) effects to inject account numbers, bill-to, performer organization, sub-tenant, or location into the outbound payload.

Fires from Canvas right after the outbound Health Gorilla FHIR `RequestGroup` dict is constructed and right before it is POSTed to Health Gorilla. Read-only — any effects returned by handlers are discarded. Complements `LAB_ORDER_COMMAND__PRE_SEND`, which fires before the build and accepts override effects.

###  Payment Processor Events 
These events drive the custom [Payment Processor](/sdk/handlers-payment-processors/) handlers. They are dispatched as a user moves through a payment workflow, and the actor that initiated the workflow is set on each event (see Event Actor). Every event other than `REVENUE__PAYMENT_PROCESSOR__LIST` includes the `identifier` of the processor it targets, so a handler only acts when the identifier matches its own.
The `identifier` is the unique id of the payment processor handler the event is intended for. Canvas derives it from the handler's class (its module path and class name) and exposes it on the handler as `self.identifier`; it is the same value the handler advertises via the [`PaymentProcessorMetadata`](/sdk/payment-processor-effect/#paymentprocessormetadata) effect when responding to `REVENUE__PAYMENT_PROCESSOR__LIST`.
REVENUE__PAYMENT_PROCESSOR__LIST

  - Responds to `LAB_REPORT_CREATED` [event](/sdk/events/#labs)
  - Loads and parses the [Lab Report data model](/sdk/data-labs/#labreport) to identify [lab values](/sdk/data-labs/#labvalue) flagged as abnormal
  - Returns a [task effect](/sdk/effect-tasks/#adding-a-task)

##  handlers/ 
###  abnormal_lab_handler.py 
**Purpose and Functionality**
This file defines a handler called AbnormalLabHandler for use with the Canvas Medical SDK. Its primary function is to monitor for the creation of new laboratory reports (`LAB_REPORT_CREATED` events). When such an event occurs, the handler inspects the report to determine if it contains any abnormal lab values. If abnormal results are found, it automatically creates a task for prompt clinical review.
**Event Handling**
  - The handler listens for the LAB_REPORT_CREATED event.
  - When triggered, it examines the relevant [lab report(/sdk/data-labs/#labreport)] for any values marked as abnormal.
**Core Logic**
  - It fetches the full LabReport instance specified by the event.
  - It filters out any reports that are for test purposes, junked, or do not belong to a patient.
  - It iterates through all values within the lab report.
  - For each value, it checks if there is a non-empty abnormal_flag.
  - If one or more abnormal values are found, it creates a task for the associated patient.
**Effects Produced**
  - Adds a new open task titled "Review Abnormal Lab Values ({count} abnormal)", labeled as "abnormal-lab" and "urgent-review" to the patient's workflow.
  - Logs the creation of the task and any errors encountered in the process.
**Error Handling**
  - If anything goes wrong (e.g., the report is missing, or there's a processing error), it logs the error and does not produce any task.
**Summary**
This handler automates the process of flagging abnormal laboratory results for clinical review within Canvas Medical, enhancing the safety net for critical lab findings by ensuring they are not overlooked.

##  handlers/ 
###  rename_note.py 
**Purpose**
This code defines a handler in a Canvas SDK plugin that automatically renames clinical notes when they are locked, using the OpenAI API to generate new titles based on the note content.
**Class Overview**
  - The main class, `Handler`, extends `BaseHandler`.
  - The handler listens for `NOTE_STATE_CHANGE_EVENT_CREATED` events—specifically, when a note's state changes (e.g., gets locked).
**Main Workflow**
  - When a relevant event fires, the `compute` method is triggered.
  - It extracts the note ID from the context.
  - If the note event corresponds to a locking action, it proceeds.
  - It collects the note content and sends it (along with instructions) to OpenAI's API, requesting a concise, descriptive title.
  - If a valid title is returned, it generates an `update` effect to rename the note in Canvas.
**OpenAI Integration**
  - The `get_note_title` function prepares headers and a request payload from the note's structured content and specific instructions.
  - It POSTS this data to OpenAI's API (note: the endpoint used, `/v1/responses`, is likely a placeholder).
  - It parses the response to extract the generated title.
**Supporting Functions**
  - `get_model`: Returns the OpenAI model name (`gpt-4.1`).
  - `get_input`: Serializes note commands (actions or entries inside the note) to JSON for use as the prompt to the language model.
  - `get_instructions`: Supplies explicit instructions and examples to OpenAI, guiding it to create short, clinically meaningful titles.
  - `is_locked_note_event`: Checks if the event is specifically a note being locked (not other state transitions).
**Error Handling**
  - Logs issues if the note ID is missing, the OpenAI call fails, or expected fields are missing in the response.
**Effect on Canvas**
  - If a new title is obtained, issues a `NoteEffect.update()` call to rename the note instance.
**Summary**
This file defines a Canvas plugin handler that listens for notes being locked, then uses OpenAI to generate and set a concise, relevant note title based on its clinical contents.

    ```
##  routes/ 
###  email_bounce.py 
The code defines an endpoint for handling bounced email events.
**Endpoint**
  - **Path:** `/crm-webhooks/email-bounce`
  - **Method:** POST
  - **Expected Body:** JSON containing `{"mrn": "valid patient MRN"}`
  - **Authorization:** Requires an API key in the `Authorization` header that matches the plugin secret `'my-api-key'`.
**Core Functionality**
  - When a POST request is received:
    - It authenticates the request by verifying the provided API key against a stored secret.
    - It retrieves the `Patient` object from the database with the given MRN (Medical Record Number) from the request body.
    - It schedules a new open task for that patient:
      - **Title:** `"Please confirm contact information."`
      - **Due Date:** 5 days from the current UTC date
      - **Label:** `"CRM"`
  - Returns a response indicating both the creation of the task and a confirmation JSON message.
**Intended Use**
This endpoint provides an automated workflow to prompt staff to confirm and update patient contact information in response to an email bounce event, improving contact data quality in clinical operations.
    ```python
    import arrow
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.effects.task import AddTask, TaskStatus
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    from canvas_sdk.v1.data import Patient
    #
    # POST /plugin-io/api/api_samples/crm-webhooks/email-bounce
    # Body: { "mrn": "valid patient MRN" }
    # Headers: "Authorization <your value for 'my-api-key'>"
    #
    class EmailBounceAPI(SimpleAPIRoute):
        PATH = "/crm-webhooks/email-bounce"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            return credentials.key == self.secrets["my-api-key"]
        def post(self) -> list[Response]:
            patient = Patient.objects.get(mrn=self.request.json()["mrn"])
            five_days_from_now = arrow.utcnow().shift(days=5).datetime
            task_effect = AddTask(
                patient_id=patient.id,
                title="Please confirm contact information.",
                due=five_days_from_now,
                status=TaskStatus.OPEN,
                labels=["CRM"],
            )
            return [task_effect.apply(), JSONResponse({"message": "Task Created"})]
    ```
###  hello_world.py 
This code defines a simple API endpoint which handles requests to the path `/hello-world`. When a GET request is made to this endpoint, the API responds with a JSON message that says "Hello world!".
**Authentication**
The endpoint requires an API key for authentication. The client must provide an API key (as a header called `Authorization`). The provided key is compared to a value stored in `self.secrets["my-api-key"]`. If the keys match, authentication is successful and the request is allowed; otherwise, it will be denied.
**Response**
A GET request to `/plugin-io/api/api_samples/hello-world` (when authenticated) returns a JSON response in the following format:
    ```json
    {
      "message": "Hello world!"
    }
    ```
    ```python
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    #
    # GET /plugin-io/api/api_samples/hello-world
    # Headers: "Authorization <your value for 'my-api-key'>"
    #
    class HelloWorldAPI(SimpleAPIRoute):
        PATH = "/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            return credentials.key == self.secrets["my-api-key"]
        def get(self) -> list[Response]:
            return [JSONResponse({"message": "Hello world!"})]

##  handlers/ 
###  aws_manip.py 
**Purpose**
This code defines a SimpleAPI handler that exposes REST endpoints for managing objects in an Amazon S3 bucket using the Canvas SDK's AWS S3 client.
**Class Overview**
  - The main class, `AwsManip`, extends `SimpleAPI`.
  - It creates an S3 client using credentials stored in plugin secrets.
**Main Workflow**
  - `GET /list_items` — Lists all objects in the configured S3 bucket.
  - `GET /get_item/<item_key>` — Retrieves an object's content by its key.
  - `GET /presigned_url/<item_key>` — Generates a presigned URL for temporary (1-hour) access to an object.
  - `POST /upload_item/<item_key>` — Uploads content to S3, handling both text and binary content types.
  - `DELETE /delete_item/<item_key>` — Deletes an object from S3 by key.
**S3 Client Integration**
  - The `_s3_client` method creates an `S3` client instance from `canvas_sdk.clients.aws.libraries`, configured with `S3Credentials` from plugin secrets.
  - Each endpoint checks `client.is_ready()` before performing operations.
    ```python
    from http import HTTPStatus

# Charting API Examples

Source: https://docs.canvasmedical.com/sdk/example-charting_api_examples/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/charting_api_examples) for this plugin on GitHub.
This example plugin provides several examples of APIs you might define when automating charting in Canvas.
  - Notes
    - Creating a note
    - Getting information about a note
    - Searching for notes by patient, type, and date of service
    - Adding billing line items to a note
  - Commands
    - Creating a command
    - Creating multiple commands from a single request
    - Creating a command and committing it in a single request
##  Configuration 
All of the example endpoints in this plugin are protected with [API key authentication](https://docs.canvasmedical.com/sdk/handlers-simple-api-http/#api-key-1). Once installed, you'll need to set the `simpleapi-api-key` value on the plugin's configuration page in your EHR.
##  Endpoint Documentation 
###  Search Notes 
`GET /plugin-io/api/charting_api_examples/notes/`
This endpoint allows the retrieval of an optionally filtered set of notes. The results are paginated, and the client can exert some control over the page size. The response body will include an attribute, `next_page`, which will either contain a URL to the next page of the same filtered set or be `null`, indicating there are no more records to fetch.
####  Optional query parameters: 
#####  limit 
_int_
Determines the number of results to return per page.
  - If unspecified, the default is 10.
  - If a number less than 1 is specified, 1 will be used.
  - If a number greate than 100 is specified, 100 will be used.
#####  offset 
_int_
Number of records to skip with returning results. When used with **limit** , this enables the pagination of results.
  - If unspecified, the default is 0.
  - If a number less than 0 is specified, 0 will be used.
#####  patient_id 
_str_
Filters the notes returned to just those associated with the given patient.
#####  note_type 
_coding_
You can search by just the code value or you can search by the system and code in the format "system|code" (e.g. `http://snomed.info/sct|308335008`).
#####  datetime_of_service 
_iso8601 formatted datetime string_
Exact match for notes with the given datetime.
#####  datetime_of_service__gt 
_iso8601 formatted datetime string_
Filter to notes occurring after the given datetime.
#####  datetime_of_service__gte 
_iso8601 formatted datetime string_
Filter to notes occurring at or after the given datetime.
#####  datetime_of_service__lt 
_iso8601 formatted datetime string_
Filter to notes occurring before the given datetime.
#####  datetime_of_service__lte 
_iso8601 formatted datetime string_
Filter to notes occurring at or before the given datetime.
####  Example Request 
    ```bash
    curl --request GET \
      --url 'https://training.canvasmedical.com/plugin-io/api/charting_api_examples/notes/?limit=2&offset=4' \

##  routes/ 
###  commands.py 
This file provides an example of how to define REST API endpoints in a Canvas-based plugin for inserting medical charting commands to clinical notes, with validation, error handling, and support for both single and batch command operations.
**Endpoints**
  1. `/notes/<id>/diagnose/` (POST):
     - Adds a DiagnoseCommand to the specified note.
     - Expects a JSON body with at least an "icd10_code" parameter, and optionally "committed" (boolean).
     - If "committed" is true, the diagnose command is also committed immediately after being originated.
     - Handles missing attribute errors and note-not-found situations gracefully, responding with appropriate error messages and status codes.
  2. `/notes/<id>/prechart/` (POST):
     - Initiates (originates) several commands at once for a note: ReasonForVisitCommand, PhysicalExamCommand, DiagnoseCommand, and PlanCommand.
     - Designed to quickly set up the structure for clinical pre-charting with a single request.
**Implementation Highlights**
  - The API is protected with API key authentication via `APIKeyAuthMixin`.
  - Uses utility functions (`get_note_from_path_params`, `note_not_found_response`) to locate notes and standardize error responses.
  - Returns both command effects (operations that are intended to be executed in the Canvas system) and standard JSON responses.
  - Uses status codes according to best practices, addressing Python version differences by using explicit numeric codes where needed.
**Canvas SDK Features Used**
  - Commands: `DiagnoseCommand`, `PhysicalExamCommand`, `PlanCommand`, `ReasonForVisitCommand` — each representing an action to be performed on a note.
  - Effects: Chainable "originate" (create/begin the command) and "commit" (finalize/commit the command).
    ```python
    from http import HTTPStatus
    from uuid import uuid4
    from canvas_sdk.commands import (
        DiagnoseCommand,
        PhysicalExamCommand,
        PlanCommand,
        ReasonForVisitCommand,

        This shows how you can create an endpoint to insert a particular type of

###  notes.py 
Defines an API endpoint for working with clinical notes. The API supports listing, creating, and retrieving notes, with filtering and pagination features. Authentication is handled through an API key.
**Endpoints**
  - **GET /notes/**
    - Returns a paginated list of notes.
    - Supports filters:
      - `patient_id`: Filter notes for a specific patient.
      - `note_type`: Filter by note type (by code or by system| code).  
---|---  
      - `datetime_of_service`, `datetime_of_service__gt`, `datetime_of_service__gte`, `datetime_of_service__lt`, `datetime_of_service__lte`: Date/time based filters.
    - Pagination:
      - `limit`: Number of results (default 10, min 1, max 100).
      - `offset`: Pagination offset (default 0, min 0).
    - If more results exist after the current page, a `next_page` link is included.
    - Returns a JSON object with `notes` (list), `count` (number of notes returned), and `next_page` (URL or None).
  - **POST /notes/**
    - Creates a new note.
    - Requires a JSON body with:
      - `note_type_id`, `datetime_of_service` (as string), `patient_id`, `practice_location_id`, `provider_id`, `title`
    - If required fields are missing, returns an error with status 422.
    - Otherwise, initiates note creation and immediately returns an accepted response (`202 Accepted`) with a confirmation message.
  - **GET /notes/ <note-id>/**
    - Returns details for a specific note by its ID.
    - If the note doesn't exist, returns a "not found" response.
    - If found, returns note details, including its state (from `CurrentNoteStateEvent`), patient/provider IDs, datetime, and type info (id, name, coding).
**Helpers and Utilities**
  - Uses utilities such as `get_note_from_path_params` and `note_not_found_response` for ID lookup and error handling.
  - Uses Django-style ORM filters and queryset slicing.
  - Uses the `arrow` library for date parsing.
  - All endpoints expect authentication via the `simpleapi-api-key`.

###  billing_line_items.py 
This file defines an API endpoint for adding billing line items (represented by CPT codes) to a note.
**Key Components**
  - Imports utility and SDK classes for effects, API handling, and response generation.
  - Defines a class, `BillingLineItemAPI`, which inherits API authentication and handling functionalities.
  - Registers an HTTP POST endpoint at `/notes/<note-id>/billing_line_items/`.
  - Expects an API key in the request header for authentication.
  - Expects the request body to be JSON with a "cpt_code" attribute.

##  util.py 
This file provides utility functions for working with Note objects. The utilities include input validation, standard JSON error responses, and fetching Note objects by ID.
**Function: is_valid_uuid**
This function checks whether a given string is a valid UUID (specifically version 4).
  - Takes a single string argument.
  - Returns True if the string is a properly formatted version 4 UUID, False otherwise.
**Function: note_not_found_response**
This function returns a standardized JSON error response indicating that a requested Note was not found.
  - Uses JSONResponse from the SDK.
  - Sets the response status to HTTP 404 (NOT FOUND) and the body to {"error": "Note not found."}.
**Function: get_note_from_path_params**
This function attempts to retrieve a Note object using a dictionary of path parameters.
  - Extracts the "id" from path_params.
  - Validates the ID as a UUID using is_valid_uuid.
  - If invalid, returns None.
  - If valid, attempts to retrieve a Note object with the given ID (using Note.objects.get).
  - If the Note does not exist, catches the DoesNotExist exception and returns None.
  - Returns the Note object if found, or None if not found/invalid.
**Imports and External Dependencies**

# Example Chart Application

Source: https://docs.canvasmedical.com/sdk/example-example_chart_app/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/example_chart_app) for this plugin on GitHub.
An example custom UI Application for the patient chart. This particular application loads the active staff user and displays some attributes about them (ex: their name), and it also loads templated HTML and JavaScript to make a REST call to a user-defined endpoint, right in the Canvas EMR.
##  SDK Features 
  - Creates a `GET` [Simple API](/sdk/handlers-simple-api-http/) endpoint that retrieves the logged in [Staff user](/sdk/data-staff/) from the event context, [renders a template](/sdk/layout-effect/#custom-html-and-django-templates), and returns HTML content
  - Creates a `POST` [Simple API](/sdk/handlers-simple-api-http/) endpoint that [creates a task](/sdk/effect-tasks/#adding-a-task)
  - Defines a custom template containing JavaScript that makes a REST call to the user-defined `POST` endpoint above
  - Adds an [Application](/sdk/handlers-applications/) effect that, on open, returns a [LaunchModalEffect](/sdk/layout-effect/#modals) in the right chart pane with content from the `GET` endpoint
##  Configuration 
These SimpleAPI endpoints use the [StaffSessionAuthMixin](/sdk/handlers-simple-api-http/#staff-session)
The `CANVAS_MANIFEST.json` file defines attributes specific to the Application, including scope (`patient_specific`) and icon image.

##  templates/ 
###  custom-ui.html 
This is the html template called by the [`render_to_string` function](/sdk/layout-effect/#custom-html-and-django-templates) with a `logged_in_staff` object. It contains styling and custom Javascript to call the user-defined POST endpoint when a specific element is clicked.
##  applications/ 
###  my_application.py 
This file defines an application plugin for Canvas Medical using the Canvas SDK. It includes a custom application (`MyChartApplication`) and an API (`MyApi`) for rendering a modal user interface pane and handling related actions, such as adding tasks.
**MyChartApplication Class**
  - Subclasses the `Application` class from the Canvas SDK.
  - The `on_open` method is triggered when the application is opened. It retrieves the current patient's ID from `self.context`.
  - It returns a `LaunchModalEffect`, which opens a custom modal UI in the right chart pane. The URL for this modal includes the patient ID as a query parameter.
**MyApi Class**
  - Subclasses both `StaffSessionAuthMixin` and `SimpleAPI`, enabling API definition with authentication.
  - Defines two endpoints using the `@api` decorator: a GET and a POST.
**GET /custom-ui**
  - Endpoint: `/custom-ui`
  - Retrieves the logged-in staff user via the header `"canvas-logged-in-user-id"` and the Canvas SDK Staff data model (but it could retrieve any data!)
  - Renders a template (`templates/custom-ui.html`) with context including the logged-in staff and the selected patient ID.
  - Returns the rendered HTML as an `HTMLResponse` with HTTP 200 (OK) status.
**POST /add-task**
  - Endpoint: `/add-task`
  - Creates a new task for the specified patient (using `patient_id` from the posted JSON payload).
  - Sets the task to be due in 5 days from the current UTC time and sets its status to open.
  - Returns two responses:
    - The effect to add a task (which also triggers any related UI updates).
    - A JSON response with a success message and HTTP 202 (Accepted) status.
**Miscellaneous**
  - Imports various components and utilities from the Canvas SDK, such as effects for UI actions, response types, authentication mixins, and template rendering.
  - Uses the `arrow` library for time/date handling.
**Summary**
The code provides a Canvas plugin that opens a modal UI displaying custom content for a selected patient. It can also create a new patient-related task when a specific endpoint is called, handling user authentication and returning appropriate UI and API responses. The flow is tailored to staff users interacting with patient charts.

##  handlers/ 
###  pdf_manip.py 
**Purpose**
This code defines a SimpleAPI handler that exposes REST endpoints for processing PDF documents using the Extend AI client from the Canvas SDK.
**Class Overview**
  - The main class, `PdfManip`, extends `StaffSessionAuthMixin` and `SimpleAPI`.
  - It creates an Extend AI client using an API key stored in plugin secrets.
**Main Workflow**
  - `GET /processors` — Lists all available Extend AI processors.
  - `GET /processors/<processor_id>` — Retrieves configuration for a specific processor.
  - `POST /execute` — Starts a processor run on a document from a public S3 URL.
  - `GET /status/<run_id>` — Checks the status of a run and cleans up files if completed.
  - `GET /result/<run_id>` — Retrieves the processing result for a completed run.
  - `GET /stored_files` — Lists all files stored in Extend AI.
  - `POST /delete_files` — Deletes specified files from Extend AI storage.
**Extend AI Client Integration**
  - The `_extend_client` method creates a `Client` instance from `canvas_sdk.clients.extend_ai.libraries`.
  - Error handling uses the `RequestFailed` exception from the Extend AI client structures.

    from datetime import datetime

##  handlers/ 
###  llm_manip.py 
**Purpose**
This code defines a SimpleAPI handler that exposes REST endpoints for interacting with LLM providers using the Canvas SDK's unified LLM client.
**Class Overview**
  - The main class, `LlmManip`, extends `SimpleAPI`.
  - It supports three LLM providers: Anthropic (Claude), Google (Gemini), and OpenAI (GPT Models).
  - It demonstrates structured JSON output using Pydantic models (`LlmResponse`, `Result`).
**Main Workflow**
  - `POST /animals_count/<llm_provider>` — Analyzes an image URL to count animals using LLM vision capabilities with structured JSON output.
  - `POST /chat/<llm_provider>` — Processes a multi-turn chat conversation with system, user, and model roles.
  - `POST /file/<llm_provider>` — Analyzes uploaded file content using multipart form data.
**LLM Client Integration**
  - The `_llm_client` method creates provider-specific clients (`LlmAnthropic`, `LlmGoogle`, `LlmOpenai`) with their respective settings classes.
  - Structured output is configured via `client.set_schema()` with Pydantic models extending `BaseModelLlmJson`.
  - File attachments are supported via `LlmFileUrl` for URLs and `FileContent` for binary content.

# Patient Creation Platform Sync

Source: https://docs.canvasmedical.com/sdk/example-patient_creation_platform_sync/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/example_patient_sync) for this plugin on GitHub.
##  Description 
An example of bidirectional patient creation between Canvas and a 3rd party system.
At a high level, this plugin:
  1. Adds an API endpoint to which the external system can POST a new patient object with a given system_id, which creates a patient in Canvas with an external_identifier.
  2. Configures a webhook for the PATIENT_CREATED event to automatically synchronize patient data. When a patient is created in Canvas, the webhook triggers an update (or creation) in the external system via its patient GET/POST/PATCH API, ensuring the Canvas ID is always included.
##  Sample CURL request 
Once the API endpoint POST action is created, test it is working with the following CURL command (or use a popular GUI like Postman or Bruno). Replace "training" with your Canvas instance name:
    ```plaintext
    curl --request POST \
      --url https://training.canvasmedical.com/plugin-io/api/example_patient_sync/patients \
      --header 'content-type: application/json' \
      --header 'authorization: 97f2a0f033666d29ff09ee42b3afd7e4'
      --data '{
      "firstName": "Alice",
      "lastName": "Example",
      "sexAtBirth": "F",
      "dateOfBirth": "1980-02-22",
      "partnerId": "pat_12345678"
    }'
    ```
##  Defining and Setting Secrets 
This example plugin defines four "secrets" in the manifest file:
    ```plaintext
        "variables": [
            {"name": "PARTNER_URL_BASE", "sensitive": false},
            {"name": "PARTNER_API_BASE_URL", "sensitive": false},
            {"name": "PARTNER_SECRET_API_KEY", "sensitive": true},
            {"name": "simpleapi-api-key", "sensitive": true}
        ],
    ```
Once defined in the `MANIFEST.json`, set the secrets for your plugin in the Admin UI of your Canvas EMR. [Read more](https://docs.canvasmedical.com/sdk/secrets/)
###  PARTNER_URL_BASE 
This string value will be set as the "system" in the patient external identifier that is created. A patient can have many external identifiers, so make sure this is a unique value that is searchable to find their external ID in the future. [Read more](https://docs.canvasmedical.com/sdk/effect-create-patient-external-identifier/)
###  PARTNER_API_BASE_URL 
This string value will be used when making REST API calls to a partner system (to create or update a patient record, for example). It may or may not be the same as the PARTNER_URL_BASE.
###  PARTNER_SECRET_API_KEY 
If accessing a partner API requires authorization, this can define the auth secret to enable the API handshake.
###  simpleapi-api-key 
This is the authorization needed for Canvas when using APIKeyAuthMixin. [Read more](https://docs.canvasmedical.com/sdk/handlers-simple-api-http/#session)

##  routes/ 
###  patient_create_api.py 
**Purpose**
The code defines an HTTP API endpoint for creating new patient records in Canvas from a third-party system. It authenticates requests using an API key and expects data in JSON format.
**Authentication**
The endpoint uses APIKeyAuthMixin, which requires clients to provide a valid API key in the request headers for authorization.
**Endpoint Details**
  - **Route:** POST /patients
  - **Description:** Accepts and processes patient creation requests sent by external systems.
**Request Handling**
  - Expects a JSON body describing the patient. If the JSON body is not a dictionary, returns a "400 Bad Request".
  - Extracts and processes the following fields from the request:
    - `firstName`: Patient's first name.
    - `lastName`: Patient's last name.
    - `dateOfBirth`: Patient's date of birth, parsed and converted to a date object.
    - `sexAtBirth`: Patient's sex at birth; attempts to standardize and map to one of the PersonSex enum values (`SEX_FEMALE`, `SEX_MALE`, `SEX_OTHER`, `SEX_UNKNOWN`). Unrecognized values are ignored.
    - `partnerId`: An external identifier for the patient, which is combined with a secret value (`PARTNER_URL_BASE`) to create a unique identifier object.
**Patient Creation**
  - Constructs a Patient object with the collected and parsed data.
  - Attaches the external identifier from the requesting system.
**Response**
  - Issues two actions in its response list:
    - Requests the creation of the Patient record (an Effect for persistence in Canvas).
    - Returns a JSON response (HTTP 202 Accepted) containing the external identifier information (system and value), indicating the request was accepted.
**Error Handling**
  - If the request body is not valid JSON or not a dictionary, the endpoint immediately returns a 400 Bad Request with an error message.
**Dependencies**
  - Relies on the Canvas SDK for authentication, response creation, effect handling, and data models.
  - Uses the arrow library for robust date parsing.

###  patient_sync.py 
**Summary**
This file defines a synchronization handler for patient data between the Canvas Medical platform and an external partner system. It listens for the event when a patient is created on Canvas and then ensures that this patient also exists (and is linked via an external identifier) in the partner system. The handler manages bidirectional lookup and updates of patient IDs between the two systems.
**Details of Operation**
  - The core class, `PatientSync`, inherits from `BaseHandler` and is triggered by the `PATIENT_CREATED` event in Canvas.
  - It uses configuration secrets and environment variables to determine endpoints, authentication headers, and other partner-specific parameters.
  - When a new patient is created in Canvas, the handler:
    1. Checks if the patient already has an external identifier linking them to the partner system.
    2. If not, attempts to look up the patient in the partner system using the Canvas patient ID by issuing a GET request.
    3. If an existing patient ID is found in the partner system, or after determining a new patient needs to be created, it prepares a payload with patient details.
    4. Issues a POST request to the partner API to either create or update the patient there.
    5. If creating, the handler expects the partner system to return the newly created patient's external ID.
    6. Handles duplicate creation attempts (HTTP 409) by simply returning without making changes.
    7. When a new external identifier is obtained, triggers an Effect to update the Canvas patient record with this identifier.
**Technical Implementation**
  - Secrets such as API keys and base URLs are used for secure access and configuration.
  - The handler functions as a stateless, event-driven adapter to maintain patient cross-system consistency.
  - HTTP request functionality is abstracted via Canvas SDK utilities.
  - Effects (a pattern used in Canvas plugins) are queued to perform changes in Canvas asynchronously and safely.
  - Logging is imported but not shown in use in the provided code.
**Key Methods**
  - `lookup_external_id_by_system_url`: Searches Canvas patient external identifiers for the partner system's record.
  - `get_patient_from_system_api`: Fetches patient details from the external partner via GET request.
  - `compute`: Main workflow coordinating the above logic, handling deduplication, updates, and creation logic for patients in both systems.
**Error and Edge Cases**
  - Handles the situation where the partner system returns a duplicate on creation.
  - Deals with missing IDs by attempting lookups and only initiating creation when necessary.
  - Only updates Canvas when a new cross-system ID must be set.
**Purpose**
This plugin component ensures that every patient created in Canvas is also represented in a connected partner system, with persistent, synchronized external identifiers to enable cross-platform interoperability and data consistency.

A plugin that groups Psychiatry conditions and medications in the patient summary chart.
##  SDK Features 
  - Responds to `PATIENT_CHART__CONDITIONS` and `PATIENT_CHART__MEDICATIONS` [events](/sdk/events/#patient-chart-configuration)
  - Loads the patient conditions and medications using event context
  - Iterates through conditions to retrieve the ICD10 CodeSystem and assigns to a [Group effect](/sdk/patient-chart-group-effect/#group) list of items
  - Iterates through medications to find an RxNorm match on a list of plugin-defined medication codes and assigns to a [Group effect](/sdk/patient-chart-group-effect/#group) list of items
  - Returns the [`PatientChartGroup` effect](/sdk/patient-chart-group-effect/) with `.apply()` called

##  handlers/ 
###  my_handler.py 
This file defines two custom handlers, `Conditions` and `Medications`, using the Canvas SDK. These handlers listen for specific events related to a patient's medical chart and group relevant diagnoses or medications into a "Psychiatry" category, returning these as effects for further processing or display in the Canvas UI.
**Section:`Conditions` Handler**
  - Inherits from `BaseHandler`.
  - Listens to the `EventType.PATIENT_CHART__CONDITIONS` event (triggered when a patient's chart conditions are accessed).
  - For each condition in the event context, it looks at the `codings` list:
    - If the coding system is ICD-10 (`CodeSystems.ICD10`) and the code falls within the ICD-10 psychiatry range ("F01" to "F99") or starts with "R45." (indicating certain psychiatric symptoms), the condition is added to a group named "Psychiatry".
  - The resulting group is returned using a `PatientChartGroup` effect, applied to be consumed by other parts of the platform (such as UI rendering).
**Section:`Medications` Handler**
  - Inherits from `BaseHandler`.
  - Listens to the `EventType.PATIENT_CHART__MEDICATIONS` event (triggered when a patient's medication list is accessed).
  - Maintains an explicit list of RxNorm codes (`medication_codes`) representing psychiatric or relevant medications.
  - For each medication in the event context, it looks at the `codings` list:
    - If the coding system is RxNorm (`CodeSystems.RXNORM`) and the code (converted to integer) is in the handler's medication list, the medication is added to the "Psychiatry" group.
  - The resulting group is returned using a `PatientChartGroup` effect, again allowing psychiatric medications to be grouped in the UI.
**Section: Canvas SDK Constructs Used**
  - **Events:** Listens for specific event types (patient chart conditions or medications).
  - **Effects:** Returns grouping instructions as `PatientChartGroup` effects, making downstream processing or UI changes possible.
  - **Grouping:** Uses the `Group` object to label and prioritize (with `priority=100`) psychiatric items, and the `PatientChartGroup` to wrap effect logic for patient chart groupings.
**Section: Implementation Details**
  - The handlers use dictionary storage for groups but always construct only a single "Psychiatry" group.
  - ICD-10 and RxNorm code checks strictly conform to predefined domain ranges or explicit code lists.

# PayTheory Payment Processor

Source: https://docs.canvasmedical.com/sdk/example-paytheory_payment_processor/

> **Note:** [View the source](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/paytheory-payment-processor) for this plugin on GitHub.
This Canvas EMR plugin integrates [Pay Theory](https://paytheory.com) as a custom credit card [payment processor](/sdk/handlers-payment-processors/), letting Canvas collect payments and manage a patient's saved cards through a third-party provider instead of the built-in Stripe integration.
##  SDK Features 
  - Extends the [`CardPaymentProcessor`](/sdk/handlers-payment-processors/#cardpaymentprocessor) handler
  - Responds to the [`REVENUE__PAYMENT_PROCESSOR__*` events](/sdk/events/#payment-processor-events)
  - Renders tokenization forms with the [`PaymentProcessorForm`](/sdk/payment-processor-effect/#paymentprocessorform) effect and [Django templates](/sdk/layout-effect/#custom-html-and-django-templates)
  - Charges cards and returns a [`CardTransaction`](/sdk/payment-processor-effect/#cardtransaction) effect
  - Lists, adds, and removes saved cards with the [`PaymentMethod`](/sdk/payment-processor-effect/#paymentmethod), [`AddPaymentMethodResponse`](/sdk/payment-processor-effect/#addpaymentmethodresponse), and [`RemovePaymentMethodResponse`](/sdk/payment-processor-effect/#removepaymentmethodresponse) effects
  - Reads configuration from plugin [variables](/sdk/secrets/) and declares `url_permissions` for the Pay Theory JS SDK

##  handlers/ 
###  paytheory_payment_processor.py 
**Purpose and Functionality**
This file defines `PayTheoryPaymentProcessor`, a subclass of `CardPaymentProcessor`. It implements the methods Canvas calls throughout a payment workflow: rendering the tokenization forms, charging a card, and listing/adding/removing a patient's saved cards. Card data is tokenized client-side by Pay Theory's JS SDK, so the plugin never handles raw card numbers.
**Core Logic**
  - `payment_form` / `add_card_form` render the Pay Theory JS SDK form (via a Django template) for paying or saving a card.
  - `charge` sends the tokenized payment method to Pay Theory's GraphQL API and maps the result onto a `CardTransaction`, treating `PENDING`/`SETTLED`/`SUCCESS`/`SUCCEEDED` statuses as successful.
  - `payment_methods` maps a patient to a Pay Theory payor (via `canvas_patient_id` metadata) and returns their saved cards as `PaymentMethod` effects.
  - `add_payment_method` / `remove_payment_method` save and disable cards for the patient's payor.

##  handlers/ 
###  my_web_app.py 
This file defines a simple web application, MyWebApp, that serves HTML, JavaScript, and CSS content.
**Authentication**
The app uses session credentials to check if a user is logged in before providing access to its endpoints. This is done in the authenticate method, which returns True only if a logged-in user exists.
**Endpoints**
  - **/app/patient-portal-application** :
    - Retrieves the current logged-in Patient using an ID supplied in the request headers.
    - Renders an HTML template ("static/index.html") and supplies the patient's first and last name as context variables.
    - Returns a rendered HTML page as the response.
  - **/app/main.js** :
    - Serves the contents of "static/main.js" as JavaScript.
  - **/app/styles.css** :
    - Serves the contents of "static/styles.css" as CSS.
**Template Rendering**
All files (HTML, JS, CSS) are rendered using the Canvas SDK's render_to_string function, allowing the inclusion of dynamic server-side data, especially for the HTML response.
**Security**
Only authenticated (logged-in) users can access any endpoint. The app enforces this globally by overriding the authenticate method.
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import HTMLResponse, Response

    class MyWebApp(SimpleAPI):
        PREFIX = "/app"
        # Using session credentials allows us to ensure only logged in users can
        # access this.
        def authenticate(self, credentials: SessionCredentials) -> bool:
            return credentials.logged_in_user != None

##  assets/ 
###  icon.png 
This icon is displayed in the portal menu.
##  applications/ 
###  my_application.py 
The code defines a custom application called `MyApplication`, which is the mechanism for registering the application in the portal menu..
**Key Functionality**
  - The core implementation is within the `on_open` method, which handles the application's "open" event.
  - When the application is opened, it triggers a launch effect (`LaunchModalEffect`) that opens an iframe modal.
  - The iframe modal displays the content found at the URL `/plugin-io/api/example_patient_portal_page/app/patient-portal-application`.
  - The effect specifically targets the main page area (`target=LaunchModalEffect.TargetType.PAGE`) for embedding.
  - The `on_open` method is a customization point where additional logic could be inserted—for example, dynamic URL selection based on application state or data.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class MyApplication(Application):
        """An embeddable application that can be registered to Canvas."""
        def on_open(self) -> Effect:
            """Handle the on_open event."""
            # Implement this method to handle the application on_open event.
            # You can look up data here to be used in knowing what to launch, if
            # what you're launching depends on some dynamic criteria.
            return LaunchModalEffect(
                # This URL is what will get iframed. It can be hosted elsewhere,
                # or it could be hosted by your plugin! Canvas plugins can serve
                # html, css, js, or json.
                #
                # If embedding a remote URL, be sure to declare it in the URL
                # permissions section of your plugin's CANVAS_MANIFEST.json
                url="/plugin-io/api/example_patient_portal_page/app/patient-portal-application",
                target=LaunchModalEffect.TargetType.PAGE,
            ).apply()
    ```
##  static/

# Customize Patient Portal with Widgets

Source: https://docs.canvasmedical.com/sdk/example-portal-customization-widgets/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_portal_plugin) for this plugin on GitHub.
##  Description 
The Patient Portal Widgets Plugin provides various widgets for the patient portal. The plugin listens to the `PATIENT_PORTAL__WIDGET_CONFIGURATION` event.
##  Widgets 
###  Header Widget 
The Header Widget displays the patient's preferred name and has quick links for messaging and scheduling.
For more, visit the [Canvas SDK documentation](https://docs.canvasmedical.com/sdk/data-patient/)
###  Care Team Widget 
It is used to display a compact widget in the Patient Portal that lists the active care team members for a patient.
It renders a scrollable list in a compact plugin format of all active members.
For more information, visit the [Canvas SDK documentation](https://docs.canvasmedical.com/sdk/data-care-team/).
###  Footer Widget 
The Footer Widget displays the support contact information for the patient.
##  Secrets 
The Patient Portal Plugin uses the following secrets:
  - `BACKGROUND_COLOR`: The background color for the widgets. Defaults to `#17634d`.
  - `EMERGENCY_CONTACT`: The emergency contact information. Defaults to `1-888-555-5555`.
In order to deal with `SECRETS` take a look at the [SDK documentation](https://docs.canvasmedical.com/sdk/secrets/).

##  templates/ 
###  care_team_widget.html 
###  header_widget.html 
###  footer_widget.html 
##  handlers/ 
###  patient_portal_handler.py 
**Purpose**
The code defines a handler, PatientPortalHandler, for the Canvas Medical SDK that renders custom widgets on the patient portal within Canvas. It listens for a specific widget configuration event and responds by displaying a set of widgets (header, care team, and footer) with certain configurable properties.
**Event Handling**
The handler is triggered (via RESPONDS_TO) when the event type PATIENT_PORTAL__WIDGET_CONFIGURATION occurs. When Canvas requests portal widget configuration for a patient, this handler gets called.
**Widgets Produced**
  - **Header Widget** : Collects basic patient information (first name, last name, etc.), constructs a "preferred full name," and passes it to an HTML template along with a configurable background color (using either a secret or a default).
  - **Care Team Widget** : Fetches the patient's active care team members. For each member, gathers name components, professional role, profile photo URL, and composes formatted display strings. This list is rendered in a compact widget, styled with the background color as a title color.
  - **Footer Widget** : Renders a footer using a background color and an emergency contact number, both customizable via secrets, falling back to sensible defaults if not specified.
**Widget Rendering**
For each widget, an appropriate HTML template is rendered with the relevant payload/context, and the widget is then wrapped as a PortalWidget with defined size and priority. These effects are returned as a list which the Canvas platform uses to display each widget on the patient portal.
**Customization and Defaults**
Two elements are customizable via the plugin's secrets dictionary:
  - BACKGROUND_COLOR: Sets the color for visual elements (widgets, titles).
  - EMERGENCY_CONTACT: Sets the emergency contact number in the footer.
If these are not provided, default values are used:
  - DEFAULT_BACKGROUND_COLOR = "#17634d"
  - DEFAULT_EMERGENCY_CONTACT = "1-888-555-5555"
**Summary**
This file enables a Canvas plugin to inject and style custom patient-facing widgets: a personalized header, a care team overview, and an emergency contact panel, all triggered when the platform requests configuration for the patient portal widgets. It leverages data models and template rendering of the Canvas SDK, with runtime customization via plugin secrets.

##  handlers/ 
###  handler.py 
This file defines a custom button handler. It provides functionality to send all prescription commands associated with a specific note when the button is activated.
  - The main class, `SendPrescriptionButtonHandler`, inherits from `ActionButton` and represents a custom action button shown in the UI (specifically, at the note footer).
  - The button is labeled "Send Prescriptions" and assigned a unique key "SEND_ALL_PRESCRIPTIONS".
**Button Handling Logic**
  - The `handle` method is the core logic, executed when the user clicks the button.
  - It obtains the `note_id` from the plugin execution context (self.context).
  - It queries the database for all commands of type `"prescribe"` that are committed (i.e., have an associated committer) and belong to the given note.
  - For each qualifying command, it creates a `PrescribeCommand`, sets its UUID to match the command, and calls `send()`, which returns an `Effect`.
  - All created effects are collected into a list and returned; these effects trigger the actual process of sending prescriptions.
    ```python
    from canvas_sdk.commands import PrescribeCommand
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.v1.data import Command
    class SendPrescriptionButtonHandler(ActionButton):
        BUTTON_TITLE = "Send Prescriptions"
        BUTTON_KEY = "SEND_ALL_PRESCRIPTIONS"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_FOOTER
        def handle(self) -> list[Effect]:
            note_id = self.context.get("note_id")
            effects = []
            # get all committed prescribe commands
            prescribe_commands = Command.objects.filter(note_id=note_id, schema_key="prescribe", committer__isnull=False)
            for command in prescribe_commands:
                prescribe = PrescribeCommand()
                prescribe.command_uuid = str(command.id)
                effects.append(prescribe.send())
            return effects
    ```
##  Customization 
###  Button Appearance 
You can customize the button by modifying the class attributes:
    ```python
    BUTTON_TITLE = "Your Custom Title"    # Change button text
    BUTTON_KEY = "YOUR_UNIQUE_KEY"        # Change button identifier
    ```
###  Button Location 
Change where the button appears by modifying:
    ```python
    BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_FOOTER  # or other locations
    ```

##  handlers/ 
###  email_manip.py 
**Purpose**
This code defines a SimpleAPI handler that exposes REST endpoints for managing email operations via the Canvas SDK's SendGrid client.
**Class Overview**
  - The main class, `EmailManip`, extends `SimpleAPI`.
  - It creates a SendGrid `EmailClient` using an API key stored in plugin secrets.
  - It uses the plugin cache system for storing webhook callback data.
**Main Workflow**
  - `POST /send_email` — Sends an email with optional inline images and file attachments.
  - `POST /emails_sent` — Queries sent emails with optional filters for recipient and date.
  - `GET /email_events/<message_id>` — Retrieves email events for a specific message.
  - `POST /inbound_webhook` — Enables/disables the SendGrid inbound parse webhook.
  - `GET /inbound_webhook` — Gets the current inbound webhook configuration status.
  - `POST /outbound_webhook` — Enables/disables the SendGrid outbound event webhook.
  - `GET /outbound_webhook` — Gets the current outbound webhook configuration status.
  - `POST /inbound_email` — Receives and caches parsed inbound emails from SendGrid.
  - `GET /inbound_email` — Retrieves the most recent inbound email from cache.
  - `POST /outbound_email_status` — Receives and caches outbound email status events.
  - `GET /outbound_email_status` — Retrieves the most recent outbound status events from cache.
**SendGrid Client Integration**
  - The `_sendgrid_client` method creates an `EmailClient` instance from `canvas_sdk.clients.sendgrid.libraries`.
  - Email composition uses structured types: `Address`, `Recipient`, `BodyContent`, `Attachment`, and `Email`.
  - Error handling uses the `RequestFailed` exception from the SendGrid client structures.

# Twilio SMS/MMS

Source: https://docs.canvasmedical.com/sdk/example-twilio_sms_mms/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/twilio_sms_mms) for this plugin on GitHub.
##  Description 
Plugin that provides a SimpleAPI for sending and receiving SMS/MMS messages using the Canvas SDK's Twilio client. It supports listing phone numbers, sending messages, retrieving message history and media, managing inbound webhooks, handling delivery status callbacks, and auto-replying to inbound messages. Includes a chart application that renders a form interface for SMS management directly from the chart.
##  Configuration 
This example plugin defines the following "secrets" in the manifest file:
    ```plaintext
        "variables": [
            {"name": "TwilioAccountSID", "sensitive": true},
            {"name": "TwilioAPIKey", "sensitive": true},
            {"name": "TwilioAPISecret", "sensitive": true}
        ],
    ```
Once defined in the `MANIFEST.json`, set the secrets for your plugin in the Admin UI of your Canvas EMR. [Read more](https://docs.canvasmedical.com/sdk/secrets/)

##  handlers/ 
###  sms_manip.py 
**Purpose**
This code defines a SimpleAPI handler that exposes REST endpoints for managing SMS/MMS operations via the Canvas SDK's Twilio client.
**Class Overview**
  - The main class, `SmsManip`, extends `StaffSessionAuthMixin` and `SimpleAPI`.
  - It creates a Twilio `SmsClient` using credentials stored in plugin secrets (Account SID, API Key, API Secret).
**Main Workflow**
  - `GET /phone_list` — Retrieves all phone numbers associated with the Twilio account, including capabilities and webhook configuration.
  - `GET /message_list/<number>/<direction>` — Lists messages for a specific phone number filtered by direction (from/to).
  - `GET /message/<message_sid>` — Retrieves details of a specific message.
  - `GET /medias/<message_sid>` — Retrieves all media attachments for a specific message.
  - `DELETE /message_delete/<message_sid>` — Deletes a specific message.
  - `POST /sms_send` — Sends an SMS message with optional status callback URL.
  - `POST /inbound_webhook/<phone_sid>` — Configures the inbound webhook URL for a Twilio phone number.
  - `POST /outbound_api_status` — Handles status callbacks for outbound SMS messages.
  - `POST /inbound_treatment` — Processes incoming messages and sends automatic replies with optional media.
**Twilio Client Integration**
  - The `_twillio_client` method creates an `SmsClient` instance from `canvas_sdk.clients.twilio.libraries`.
  - Error handling uses the `RequestFailed` exception from the Twilio client structures.
  - Inbound message handling generates TwiML responses for automatic replies.

# Upsert Patient Metadata

Source: https://docs.canvasmedical.com/sdk/example-upsert_patient_metadata/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/upsert_patient_metadata) for this plugin on GitHub.
This plugin showcases how to store patient metadata key/value pairs from a plugin using the Canvas SDK.
In this example, we extract key-value pairs from a plan command's narrative and store them as patient metadata.

##  handlers/ 
###  my_handler.py 
This file defines a Canvas plugin handler that uses the update of a plan command as an excuse to trigger. When a user updates a plan command and includes certain key-value data in the narrative, this handler extracts that information and saves it as patient metadata.
**Narrative Parsing**
The handler retrieves the narrative text from the event context. It uses regular expressions to look for patterns of the form:
  - `key=somekey`
  - `value=somevalue`
The separator between key/value and their contents can be any character except alphanumerics, underscores, asterisks, hashes, or whitespace. For example, `key=blood_pressure*value=120/80`.
**Action Taken**
If both a key and value are found in the narrative:
  - It logs an informational message including the patient id, key, and value.
  - It returns a list containing one Effect: an upsert (create or update) of patient metadata (via PatientMetadata) for that patient, saving the found key and value.
If either the key or value is missing, no action is performed.
    ```python
    import re
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_metadata import PatientMetadata
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    class MyHandler(BaseHandler):
        """
        Extracts key-value pairs from plan update narratives and stores them as patient metadata.
        Parses narrative text for patterns like "key=somekey*value=somevalue" where the separator
        can be any non-alphanumeric character. If both key and value are found, creates or updates
        the corresponding patient metadata entry.
        Triggers on: PLAN_COMMAND__POST_UPDATE events
        Effects: PatientMetadata upsert operations
        """
        RESPONDS_TO = EventType.Name(EventType.PLAN_COMMAND__POST_UPDATE)
        def compute(self) -> list[Effect]:
            """This method gets called when an event of the type RESPONDS_TO is fired."""
            patient_id = self.context["patient"]["id"]
            fields = self.context.get("fields", {})
            narrative = fields.get("narrative", "")
            key_match = re.search(r"key=([^*#_\s]+)", narrative)
            value_match = re.search(r"value=([^*#_\s]+)", narrative)
            key = key_match.group(1) if key_match else None

# Vitals Visualizer

Source: https://docs.canvasmedical.com/sdk/example-vitals_visualizer_plugin/

> **Note:** [View the source](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/vitals_visualizer_plugin) for this plugin on GitHub.
A Canvas plugin that displays a "Visualize" button in the vitals section of the chart summary and shows interactive vital signs visualizations.
##  SDK Features 
  - Creates and responds to a [Simple API](/sdk/handlers-simple-api-http/) endpoint that [renders a template](/sdk/layout-effect/#custom-html-and-django-templates) and returns HTML content
  - Parses [Observation data model](/sdk/data-observation/) to obtain vitals data and format into readable content
  - Adds a "Visualize" [Action Button](/sdk/handlers-action-buttons/) to the vitals section of the patient chart summary.
  - Returns a [LaunchModalEffect](/sdk/layout-effect/#modals) in the right chart pane with content from the vitals endpoint.
##  Configuration 
This SimpleAPI endpoint uses the [StaffSessionAuthMixin](/sdk/handlers-simple-api-http/#staff-session)

##  templates/ 
###  vitals_visualization.html 
This is the html template called by the[ `render_to_string` function](/sdk/layout-effect/#custom-html-and-django-templates) with a `vitals_data` object. It contains styling and custom JavaScript to form the chart.
##  handlers/ 
###  vitals_api.py 
The `vitals_api.py` file defines a class-based API endpoint called `VitalsVisualizerAPI` for a Canvas Medical plugin. This endpoint provides both a user interface (HTML) and data (as JSON) for visualizing patient vitals—specifically weight, body temperature, and oxygen saturation.
  - **API Endpoint** : The endpoint is accessed at `/visualize`, and requires staff authentication via `StaffSessionAuthMixin`.
  - **Request Handling** : The main entry point is the `get()` method, which expects a `patient_id` as a query parameter.
    - If `patient_id` is missing, it returns a 400 JSON error response.
    - If present, it fetches and compiles the patient's vital sign data, then generates and returns an HTML interface for visualization.
  - **Vitals Data Extraction** : The `_get_vitals_data(patient_id)` method:
    - Queries Canvas Medical's `Observation` resource for the specified patient.
    - Filters for observations in the "vital-signs" category that are not deleted, not entered in error, and are not "Vital Signs Panel" summary records.
    - Extracts individual observations for:
      - **Weight** (converting from ounces to pounds),
      - **Body Temperature** (with default units °F if missing),
      - **Oxygen Saturation** (with default units % if missing).
    - Organizes the data into a dictionary keyed by vital sign name, each containing a list of timestamped values.
  - **HTML Visualization Rendering** : The `_generate_visualization_html(vitals_data)` method:
    - Serializes the vitals data as JSON.
    - Passes it as context to a template called `vitals_visualization.html` for rendering the UI.
  - **Error Handling and Logging** : All major steps have try/except blocks, logging errors and returning JSON error responses if needed.
**How the Components Work Together**
  - The endpoint provides a combined UI/data interface for staff to review prescribed vitals over time for a selected patient.
  - The code is built for integration into the Canvas Medical system utilizing their SDK, data models, and permission system.
  - All HTML and logic for visualization are rendered server-side using a templating mechanism.
**Dependencies and Assumptions**
  - Depends on `Observation` model/data from Canvas Medical's API SDK.
  - Uses Canvas SDK facilities for routing, API responses, session authentication, and template rendering.
  - Relies on templates being in the `templates/` folder, specifically one for vitals visualization.
  - Expects a structured logging setup.
**Returned Data Types**
  - Templated HTML (for visualization) or JSON (for errors), wrapped in Canvas SDK response objects (`HTMLResponse`, `JSONResponse`).

###  vitals_button.py 
This file adds a "Visualize" button to the patient chart's vitals section, which, when clicked, opens a modal with a visual representation of the patient's vitals data, using the Canvas plugin and effect framework.
**Class Details**
  - The class `VitalsVisualizerButton` inherits from `ActionButton`.
  - It specifies metadata such as title ("Visualize"), a unique key (`vitals_visualizer_button`), the section of the UI where it appears (vitals summary), and its priority (1).
**Functionality**
  - When a user clicks the button, the `handle` method is triggered.
  - This method constructs a URL to an API endpoint for visualizing vitals: `/plugin-io/api/vitals_visualizer_plugin/visualize?patient_id=<id>`, where `<id>` is the current patient ID.
  - The button initiates a `LaunchModalEffect`, opening a large modal on the right side of the chart pane with the title "Vitals Visualization".
  - The modal displays the contents served by the constructed URL (likely a vitals graph or dashboard).
**Integration with Canvas SDK**
  - Uses SDK classes:
    - `ActionButton` for button behaviors and placement.
    - `LaunchModalEffect` to open a modal window within the Canvas UI.
    - The effect is returned in a list, as required by the SDK's handler pattern.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.action_button import ActionButton
    class VitalsVisualizerButton(ActionButton):
        """A button that opens the vitals visualization modal."""
        BUTTON_TITLE = "Visualize"
        BUTTON_KEY = "vitals_visualizer_button"
        BUTTON_LOCATION = ActionButton.ButtonLocation.CHART_SUMMARY_VITALS_SECTION
        PRIORITY = 1
        def handle(self) -> list[Effect]:
            """Handle button click by opening vitals visualization modal."""
            # The API endpoint will be at /plugin-io/api/vitals_visualizer_plugin/visualize
            # We need to pass the patient ID in the URL
            patient_id = self.target
            return [
                LaunchModalEffect(
                    url=f"/plugin-io/api/vitals_visualizer_plugin/visualize?patient_id={patient_id}",
                    target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE_LARGE,
                    title="Vitals Visualization"
                ).apply()
            ]

# Action Buttons

Source: https://docs.canvasmedical.com/sdk/handlers-action-buttons/

Action buttons are UI elements that trigger specific actions when clicked in the Canvas UI. These buttons can be placed in different locations and can interact with runtime data to execute custom code.
##  Overview 
An `ActionButton` class allows you to define custom buttons that appear in different sections of the Canvas UI. When a user clicks the button, the action associated with the button is executed. Action buttons can be added to various locations in the UI, and you can control their visibility and behavior through effects in a handler class.
There are no limitations on the number of action buttons you can create. You can define multiple buttons in a single handler class or create separate classes for each button.
##  Creating an action button 
An action button is a [handler](/sdk/handlers-basehandler/). Subclass `ActionButton`, say where it goes with `BUTTON_LOCATION`, and implement `handle()` to say what a click does:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.action_button import ActionButton
    class PatientSummaryButton(ActionButton):
        BUTTON_TITLE = "Summary"
        BUTTON_KEY = "PATIENT_SUMMARY"
        BUTTON_LOCATION = ActionButton.ButtonLocation.CHART_PATIENT_HEADER
        def handle(self) -> list[Effect]:
            return [
                LaunchModalEffect(
                    target=LaunchModalEffect.TargetType.DEFAULT_MODAL,
                    content="<html>Your content here</html>",
                ).apply()
            ]
    ```
Then register the class under `handlers` in your `CANVAS_MANIFEST.json`:
    ```json
    {
      "components": {
        "handlers": [
          {
            "class": "my_plugin.buttons.patient_summary:PatientSummaryButton",
            "description": "Shows a summary modal from the patient header."
          }
        ]
      }
    }
    ```
###  Class attributes 
Attribute| Required| Description  
---|---|---  
`BUTTON_TITLE`| Required| The label shown on the button. Emoji are supported.  
`BUTTON_KEY`| Required| A unique identifier for the button. Canvas routes the click back to your `handle()` by this value, so give each button its own.  
`BUTTON_LOCATION`| Required| Where the button appears, as a `ButtonLocation` value.  
`PRIORITY`| Optional| Orders this button against others in the same location, lower first. Defaults to `0`, and buttons sharing a priority have no guaranteed order.  
`BUTTON_TEXT_COLOR`| Optional| The label colour as a HEX value, for example `"#FF0000"`. Defaults to whichever of black or white contrasts with the background.  
`BUTTON_BACKGROUND_COLOR`| Optional| The background colour as a HEX value, for example `"#4CAF50"`. Defaults to Canvas's grey button styling.  
###  Methods 
Method| Returns| Required| Description  
---|---|---|---  
`handle()`| `list[Effect]`| Required| Runs when the button is clicked. Return the [effects](/sdk/effects/) the click should produce, or an empty list for none.  
`visible()`| `bool`| Optional| Runs each time the button's location loads, to decide whether the button is shown. Defaults to `True`. See Dynamic, state-responsive buttons.  
    ```python
        def visible(self) -> bool:
            """Only offer the button on an encounter note."""
            note_id = self.event.context.get("note_id")
            return Note.objects.filter(dbid=note_id, note_type_version__category="encounter").exists()
    ```
###  Button locations 
The `ActionButton` class defines several locations where the button can be placed. The location is defined using the `ButtonLocation` enum. Supported button locations include:
**Location**| **Description**  
---|---  
`NOTE_HEADER`| The button will appear in the header of each note.  
`NOTE_FOOTER`| The button will appear in the footer of each note.  
`NOTE_HEADER_DROPDOWN`| The button will appear in the note header dropdown.  
`CHART_PATIENT_HEADER`| The button will appear in the patient header on both the chart and profile pages.  
`CHART_SUMMARY_SOCIAL_DETERMINANTS_SECTION`| The button will appear in the Social Determinants section of the chart summary.  
`CHART_SUMMARY_GOALS_SECTION`| The button will appear in the Goals section of the chart summary.  
`CHART_SUMMARY_CONDITIONS_SECTION`| The button will appear in the Conditions section of the chart summary.  
`CHART_SUMMARY_MEDICATIONS_SECTION`| The button will appear in the Medications section of the chart summary.  
`CHART_SUMMARY_ALLERGIES_SECTION`| The button will appear in the Allergies section of the chart summary.  
`CHART_SUMMARY_CARE_TEAMS_SECTION`| The button will appear in the Care Teams section of the chart summary.  
`CHART_SUMMARY_VITALS_SECTION`| The button will appear in the Vitals section of the chart summary.  
`CHART_SUMMARY_IMMUNIZATIONS_SECTION`| The button will appear in the Immunizations section of the chart summary.  
`CHART_SUMMARY_SURGICAL_HISTORY_SECTION`| The button will appear in the Surgical History section of the chart summary.  
`CHART_SUMMARY_FAMILY_HISTORY_SECTION`| The button will appear in the Family History section of the chart summary.  
`CHART_SUMMARY_CODING_GAPS_SECTION`| The button will appear in the Coding Gaps section of the chart summary.  
`NOTE_BODY_AUTOMATION`| The button appears as an entry in the note body's "/" (slash) command list while a clinician documents a note.  
##  Dynamic, state-responsive buttons 
Action buttons are not rendered once and cached. Canvas re-evaluates every `ActionButton` handler each time its location loads — and again whenever the location is reloaded. On each evaluation Canvas fires the [`SHOW_*_BUTTON`](/sdk/events/#action-buttons-events) event for that location and your handler's `visible()` method decides whether the button is included.
This is what makes buttons _dynamic_ : because `visible()` runs against live data every time, the same button can appear, disappear, or change its title depending on the note, the patient, or the logged-in user.
###  Reading the runtime context 
Two different events reach an `ActionButton`, and they do not carry the same context. `visible()` runs on the [`SHOW_*_BUTTON`](/sdk/events/#action-buttons-events) event for the button's location, while `handle()` runs on `ACTION_BUTTON_CLICKED` once the button is clicked. Read both through `self.event`.
####  While deciding visibility 
What `visible()` sees depends on where the button lives:
Accessor| Note and header locations| Chart summary sections  
---|---|---  
`self.event.target.id`| The id of the patient the button is rendered for| The id of the patient  
`self.event.context["user"]`| The logged-in user, as `{"type": "Staff", "id": "<staff id>"}`| The same  
`self.event.context["note_id"]`| The **database id** of the note, or `None` on a location that has no note| Not present  
"Note and header locations" means `NOTE_HEADER`, `NOTE_FOOTER`, `NOTE_BODY`, `NOTE_BODY_AUTOMATION`, `NOTE_HEADER_DROPDOWN` and `CHART_PATIENT_HEADER`. Every `CHART_SUMMARY_*_SECTION` location gets the patient and the user only, because a chart summary is not rendered inside a note.
`note_id` is a database id rather than a UUID, so look the note up with `dbid`:
    ```python
        def visible(self) -> bool:
            note_id = self.event.context["note_id"]
            return Note.objects.filter(dbid=note_id, note_type_version__category="encounter").exists()
    ```
####  When the button is clicked 
Accessor| Value  
---|---  
`self.event.context["key"]`| The `BUTTON_KEY` of the button that was clicked. Canvas uses this to route the click, so `handle()` only runs for your own.  
`self.event.context["user"]`| The logged-in user, as `{"type": "Staff", "id": "<staff id>"}`  
`self.event.context["note_id"]`| The database id of the note the button was clicked from. Present only when the button lives on a note.  
`self.event.context["line_number"]`| The note body line the clinician typed the trigger on. Present only for a `NOTE_BODY_AUTOMATION` entry.  
`self.event.target.id`| The id of the patient the button was clicked from  
###  Reloading buttons 
Because visibility is computed from live data, Canvas needs to know _when_ to re-evaluate it. A button's location is reloaded automatically after its own `handle()` runs, but you will often want to reload in response to something else changing — for example, recomputing the footer after a command is committed, or after the note transitions to a new state.
Return one of these [Reload Action Buttons](/sdk/effect-reload-action-buttons/) effects (imported from `canvas_sdk.effects.action_button`) from any handler's `handle()` or `compute()` to refresh a location's buttons:
Effect| Re-evaluates  
---|---  
`ReloadNoteActionButtonsEffect(id=<note id>)`| Every button bound to that note  
`ReloadPatientActionButtonsEffect(id=<patient id>)`| Every button bound to that patient  
A reload re-fires the [`SHOW_*_BUTTON`](/sdk/events/#action-buttons-events) events, so every button recomputes `visible()` from scratch — the button set is rebuilt rather than patched. Any handler can emit a reload, not just an `ActionButton`; Example 4 below uses plain event handlers to keep the footer in sync as the note changes.
##  Note body automations 
A note body automation puts your plugin's own entry in the note body's "/" (slash) menu, the inline list clinicians use to insert commands while documenting a note. The location exists so an automation can come from a plugin rather than only from Canvas: one entry standing in for the several [commands](/sdk/commands/) a workflow would otherwise have the clinician insert by hand.
    ```python
    from canvas_sdk.commands import PlanCommand, TaskCommand
    from canvas_sdk.commands.commands.task import AssigneeType, TaskAssigner
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.batch_originate import BatchOriginateCommandEffect
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.v1.data.note import Note
    class LipidPanelAutomation(ActionButton):
        BUTTON_TITLE = "Order lipid panel follow-up"
        BUTTON_KEY = "LIPID_PANEL_AUTOMATION"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_BODY_AUTOMATION
        def visible(self) -> bool:
            # Offer the entry only to the note's own provider.
            note_id = self.event.context.get("note_id")
            user_id = (self.event.context.get("user") or {}).get("id")
            if not note_id or not user_id:
                return False
            return Note.objects.filter(dbid=note_id, provider__id=user_id).exists()
        def handle(self) -> list[Effect]:
            note = Note.objects.filter(dbid=self.event.context["note_id"]).first()
            if note is None:
                return []
            plan = PlanCommand(
                note_uuid=str(note.id),
                narrative="Recheck lipid panel in 3 months",
            )
            task = TaskCommand(
                note_uuid=str(note.id),
                title="Call patient with lipid panel results",
                assign_to=TaskAssigner(to=AssigneeType.STAFF, id=note.provider.dbid),
            )
            # One batch, so both commands reach the note in a single update.
            return [
                BatchOriginateCommandEffect(
                    commands=[plan, task],
                    replace_line=True,
                ).apply()
            ]
    ```
It is an ordinary action button, with no separate automation class. Set `BUTTON_LOCATION` to `NOTE_BODY_AUTOMATION`, give it the usual `BUTTON_TITLE`, `BUTTON_KEY` and `PRIORITY`, and scope it with `visible()`. Canvas asks each plugin for its entries through the [`SHOW_NOTE_BODY_AUTOMATION_BUTTON`](/sdk/events/#action-buttons-events) event, whose context carries the signed-in staff member alongside the note and the patient, so an entry can be limited to particular staff as well as to particular notes or patients.
###  How Canvas renders the entry 
Behaviour| Detail  
---|---  
Position| After the native commands, ordered by `PRIORITY` then title  
Marker| A plug icon, which distinguishes it from Canvas's native automations  
When the list is built| Once, as the note loads, rather than on every keystroke  
Filtering| Client-side against `BUTTON_TITLE` as the clinician types  
The trigger line| Cleared as soon as the entry is selected, whatever `handle()` returns  
###  What `handle()` can return 
An entry is not limited to originating commands. `handle()` may return any effects, or none at all. What the location is meant for is the first row:
Returned from `handle()`| Where the commands land  
---|---  
A [`BatchOriginateCommandEffect`](/sdk/effect-batch-originate/) with `replace_line=True`| On the line the clinician typed the trigger on, replacing it, with no trailing trigger text or blank-line padding. Canvas supplies the position, so leave `line_number` unset.  
A `BatchOriginateCommandEffect` without `replace_line`| At the bottom of the note, from the effect's own `line_number=-1` default  
A single command's `originate()`| Wherever that effect places it. One command needs no batch  
Anything else, or nothing| Nothing is added to the note, and the trigger line is still cleared  
Reach for the batch whenever an entry originates **more than one** command. It updates the note body once for the whole group rather than once per command, which is faster and keeps the group together: separate originate effects each update the note on their own, so they can interleave with other writes and land out of order.
An entry does not have to write to the note at all. Because it is an ordinary action button, it can put any tool of yours behind the "/" menu, which is a shorter reach for a clinician mid-note than the app drawer. This one opens a risk calculator, and writes nothing:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.templates import render_to_string
    class AscvdRiskCalculator(ActionButton):
        BUTTON_TITLE = "ASCVD risk calculator"
        BUTTON_KEY = "ASCVD_RISK_CALCULATOR"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_BODY_AUTOMATION
        def handle(self) -> list[Effect]:
            return [
                LaunchModalEffect(
                    target=LaunchModalEffect.TargetType.DEFAULT_MODAL,
                    content=render_to_string("templates/ascvd_calculator.html"),
                    title="ASCVD risk",
                ).apply()
            ]
    ```
The clinician types `/`, picks the calculator, and it opens over the note. The trigger line is cleared either way, so the note is left exactly as it was.
##  Examples 
###  Log information when a button is clicked 
This example demonstrates a simple action button that logs some information when clicked. The button is visible only during the month of January.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers.action_button import ActionButton
    from datetime import datetime
    from logger import log
    class MyButton(ActionButton):
        BUTTON_TITLE = "🪵 Log Action"
        BUTTON_KEY = "LOG_ACTION"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_HEADER
        def visible(self) -> bool:
            # Only show this button in January
            return datetime.now().month == 1
        def handle(self) -> list[Effect]:
            log.info("Button clicked!")
            log.info(self.event.context)
            log.info(self.event.target)
            return []
    ```
###  Commit every command in a note 
This example demonstrates an action button in the note footer that commits all commands within a note. The button is always visible since the `visible()` method is not overridden.
    ```python
    import json
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers.action_button import ActionButton

    }
    class CommitButtonHandler(ActionButton):
        BUTTON_TITLE = "Commit all commands"
        BUTTON_KEY = "COMMIT_ALL_COMMANDS"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_FOOTER
        def handle(self) -> list[Effect]:
            note_id = self.context.get("note_id")
            effects = []
            for command in Command.objects.filter(note_id=note_id):
                effect_type = schema_key_to_effect_type.get(command.schema_key)
                if not effect_type:
                    raise ValueError(f"No EffectType defined for schema key '{command.schema_key}'.")
                effects.append(
                    Effect(
                        type=effect_type,
                        payload=json.dumps({"command": str(command.id)}),
                    )
                )
            return effects
    ```
###  Render HTML from a chart summary section 
In this example, we place a button in the Vitals section and define an action where the button, when clicked, displays custom HTML content to the user. For more info about `LaunchModalEffect`, check the [documentation](/sdk/layout-effect/#modals).
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from logger import log
    class VitalsButtonHandler(ActionButton):
        BUTTON_TITLE = "📊 Show Vitals Info"
        BUTTON_KEY = "SHOW_VITALS_INFO"
        BUTTON_LOCATION = ActionButton.ButtonLocation.CHART_SUMMARY_VITALS_SECTION
        def handle(self) -> list[Effect]:
            # This method will be called when the button is clicked
            log.info("Vitals info button clicked!")
            # Custom HTML content to display
            custom_html = """
            <div style="padding: 20px; background-color: #f0f8ff; border-radius: 5px;">

            # Return a LaunchModalEffect to show the custom HTML content in a modal
            return [LaunchModalEffect(

    ```
##  Note state action buttons 
`NoteStateActionButton` is a specialized `ActionButton` subclass for note footer buttons that transition a note from one state to another — locking, signing, pushing charges, deleting, and discharging, along with the appointment transitions check in, no show, cancel, and restore. It handles visibility, ordering, and the underlying state-transition effect for you, so a plugin can replace Canvas's default footer buttons with its own.
To create one, subclass `NoteStateActionButton` and set the `STATE_ACTION` class attribute to the target [`NoteStates`](/sdk/data-note/#notestates) value the button should transition the note into. Locking and signing carry extra rules, so the SDK also ships two ready-to-use subclasses — `LockNoteActionButton` and `SignNoteActionButton` — that you can register directly (or subclass) instead of setting `STATE_ACTION` yourself:
    ```python
    from canvas_sdk.handlers.action_button import (
        LockNoteActionButton,
        NoteStateActionButton,
        SignNoteActionButton,
    )
    from canvas_sdk.v1.data.note import NoteStates
    # Lock and Sign subclass the specialized bases — STATE_ACTION and their extra
    # rules are already set on those classes.
    class LockNoteButton(LockNoteActionButton):
        pass
    class SignNoteButton(SignNoteActionButton):
        pass
    # Every other transition subclasses NoteStateActionButton and sets STATE_ACTION.
    class UnlockNoteButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.UNLOCKED
    class PushChargesNoteButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.PUSHED
    class CheckInAppointmentButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.CONVERTED
    class NoShowAppointmentButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.NOSHOW
    class CancelAppointmentButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.CANCELLED
    class RestoreAppointmentButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.REVERTED
    class DeleteNoteButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.DELETED
    class RestoreNoteButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.UNDELETED
    class DischargeNoteButton(NoteStateActionButton):
        STATE_ACTION = NoteStates.DISCHARGED
    ```
Register each button as a handler in your `CANVAS_MANIFEST.json`, exactly like any other `ActionButton`.
Each button is configured automatically from its `STATE_ACTION`, so a subclass normally sets nothing else:
Attribute| Value  
---|---  
`BUTTON_LOCATION`| Always `NOTE_FOOTER`. Not overridable.  
`BUTTON_TITLE`| An imperative label for the target state, from the table below. Set it explicitly to override.  
`BUTTON_KEY`| `note_state_action__<state value>`, for example `note_state_action__LKD`. Set it explicitly to override.  
`visible()`| Implemented by the base class, which shows the button only when the transition is permitted. See Visibility.  
These are the supported transitions:
`STATE_ACTION`| Subclass| Default title| Default key  
---|---|---|---  
`NoteStates.LOCKED`| `LockNoteActionButton`| `Lock`| `note_state_action__LKD`  
`NoteStates.SIGNED`| `SignNoteActionButton`| `Sign`| `note_state_action__SGN`  
`NoteStates.UNLOCKED`| `NoteStateActionButton`| `Unlock`| `note_state_action__ULK`  
`NoteStates.PUSHED`| `NoteStateActionButton`| `Push charges`| `note_state_action__PSH`  
`NoteStates.DISCHARGED`| `NoteStateActionButton`| `Discharge`| `note_state_action__DSC`  
`NoteStates.DELETED`| `NoteStateActionButton`| `Delete`| `note_state_action__DLT`  
`NoteStates.UNDELETED`| `NoteStateActionButton`| `Restore`| `note_state_action__UND`  
`NoteStates.CONVERTED`| `NoteStateActionButton`| `Check in`| `note_state_action__CVD`  
`NoteStates.NOSHOW`| `NoteStateActionButton`| `No show`| `note_state_action__NSW`  
`NoteStates.CANCELLED`| `NoteStateActionButton`| `Cancel`| `note_state_action__CLD`  
`NoteStates.REVERTED`| `NoteStateActionButton`| `Restore`| `note_state_action__RVT`  
`Cancel` and `Restore` act on the note's appointment rather than on the note itself, so they do nothing on a note that has no appointment. `Sign` locks the note first when it is not already locked.
When a button is clicked, Canvas applies the transition's effect and reloads the footer so it reflects the note's new state.
###  Visibility 
A `NoteStateActionButton` appears only when its `STATE_ACTION` is a permitted transition from the note's current state and note type, so you don't need to override `visible()` yourself. When several are visible at once, Canvas orders them to match the order it offers the transitions for the current state.
Three buttons carry extra gates on top of that, which the base class applies for you:
Button| Also shown only when  
---|---  
`LockNoteActionButton`| The note type does **not** require a signature  
`SignNoteActionButton`| The note type **does** require a signature, and the current user has not signed since the last lock  
`Discharge`| The note type is an inpatient one  
Lock and Sign are the same underlying transition, split by whether the note type requires a signature. Because Sign hides itself only for the user who signed, a note can be signed by several users in turn, and it is re-locked only after an amend.
###  Replacing Canvas's default footer buttons 
Your state buttons appear _alongside_ Canvas's built-in state-transition buttons by default. To hide the native ones so yours replace them, answer the `NOTE_FOOTER__GET_CONFIGURATION` event with a [`NoteFooterConfiguration`](/sdk/effect-note-footer-configuration/) effect. Footer suppression is configured once per note (not per button):
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note_footer_configuration import NoteFooterConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class HideDefaultStateButtons(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.NOTE_FOOTER__GET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [NoteFooterConfiguration(hide_default_state_buttons=True).apply()]
    ```
###  Customizing when a button appears 
Override `visible()` to layer your own rules on top of the built-in checks — call `super().visible()` first so you keep everything the base already enforces, then add your conditions. Subclassing `SignNoteActionButton` means `super().visible()` still applies the sign-specific rules (signature-required, lock-first, and already-signed). This Sign button additionally hides itself while the note has staged (uncommitted) commands, because a note can't be signed until its commands are committed (reason-for-visit is auto-managed and doesn't block signing, so it's excluded):
    ```python
    from canvas_sdk.handlers.action_button import SignNoteActionButton
    from canvas_sdk.v1.data.command import Command
    class SignNoteButton(SignNoteActionButton):
        def visible(self) -> bool:
            if not super().visible():
                return False
            note_id = self.event.context.get("note_id")
            return not (
                Command.objects.filter(note_id=note_id, state="staged")
                .exclude(schema_key="reasonForVisit")
                .exists()
            )
    ```
You can gate on anything in the runtime context. For example, to show a button only to the note's provider, compare the logged-in user against the note's provider (`note.provider.id` and the user id are both Staff ids):
    ```python
        def visible(self) -> bool:
            if not super().visible():
                return False
            note_id = self.event.context.get("note_id")
            user_id = (self.event.context.get("user") or {}).get("id")
            if not note_id or not user_id:
                return False
            return Note.objects.filter(dbid=note_id, provider__id=user_id).exists()
    ```
###  Keeping the footer in sync 
`visible()` is only re-evaluated when the footer is reloaded. A transition triggered by one of these buttons reloads the footer automatically, but changes from elsewhere don't — so pair the buttons with handlers that reload the footer when the note changes by another path. For example, reload whenever a command is committed (so the Sign button reappears the instant the last command is committed) and whenever the note's state changes:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.action_button import ReloadNoteActionButtonsEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.command import Command
    class ReloadFooterOnCommandCommit(BaseHandler):
        """Reload the footer whenever any command is committed."""
        RESPONDS_TO = [
            EventType.Name(value)
            for value in EventType.values()
            if EventType.Name(value).endswith("_COMMAND__POST_COMMIT")
        ]
        def compute(self) -> list[Effect]:
            command = Command.objects.filter(id=self.event.target.id).first()
            if not command or not command.note:
                return []
            return [ReloadNoteActionButtonsEffect(id=str(command.note.id)).apply()]
    class ReloadFooterOnNoteStateChange(BaseHandler):
        """Reload the footer whenever the note transitions to a new state."""
        RESPONDS_TO = EventType.Name(EventType.NOTE_STATE_CHANGE_EVENT_CREATED)
        def compute(self) -> list[Effect]:
            note_id = self.event.context.get("note_id")
            if not note_id:
                return []
            return [ReloadNoteActionButtonsEffect(id=note_id).apply()]
    ```
##  Reference plugin 
A complete, working plugin that ties these patterns together is available as the [**note-lifecycle-example**](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/note-lifecycle-example) plugin. It demonstrates:
  - a full set of state-responsive footer buttons (Lock, Sign, Unlock, Push charges, Check in, No show, Cancel, Restore, Delete, Discharge), each appearing only when its transition is valid from the note's current state — Lock and Sign built on `LockNoteActionButton` and `SignNoteActionButton`, the rest on `NoteStateActionButton`;
  - a `HideDefaultStateButtons` handler that hides Canvas's native footer buttons so the plugin's buttons replace them;
  - `ReloadFooterOnCommandCommit` and `ReloadFooterOnNoteStateChange` handlers that keep the visible button set in sync as the note evolves.
Use it as a starting point for your own footer.

# Applications

Source: https://docs.canvasmedical.com/sdk/handlers-applications/

Applications are accessible in the app drawer and launch your content when clicked. Applications can be patient specific, or global.
##  Implementing an Application 
To add an application, your handler class should inherit from the `Application` class.
Your class must implement the `on_open()` method. In most cases, you will return a `LaunchModalEffect`, with either a URL you wish to iframe into the Canvas UI or HTML to be rendered in that iframe directly, make sure to set a `title` so users can easily recognize the application when it's minimized. You can return a single `Effect` or a list of `Effect`s from the `on_open()` method.
You can also optionally implement the `on_context_change()` method to handle context changes within the application. This method is automatically triggered when users navigate to different URLs within Canvas, allowing your application to react to contextual changes with rich information about the current page.
Context change events are currently supported for revenue workflows and include:
  - **URL information** : The current page URL that triggered the context change
  - **Patient data** : Patient information when applicable
  - **Resource-specific context** : Additional context based on the specific page:
    - `/revenue/claims/<id>` \- Includes claim data with externally exposable ID
    - `/revenue/queues/<id>` \- Includes queue data with database ID
    - `/revenue` \- Base revenue page with no additional context
This method can return an `Effect` or list of `Effect`s to perform actions when the application's context changes, or `None` if no action is needed. When `None` is returned, no effect will be added to the execution queue.
Here is an example of an implemented application class:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class IFrameApp(Application):
        def on_open(self) -> Effect | list[Effect]:
            return LaunchModalEffect(url=f"https://www.your-iframe-app.com",
                target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE, title="Your Iframe App").apply()
        def on_context_change(self) -> Effect | list[Effect] | None:
            # Access the current URL that triggered the context change
            current_url = self.event.context.get("url", "")
            # Handle claim-specific context
            if claim := self.event.context.get("claim"):
                claim_id = claim["id"]
                return LaunchModalEffect(
                    url=f"https://www.your-iframe-app.com?claim_id={claim_id}&source_url={current_url}",
                    target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
                    title=f"Your Iframe App - Claim {claim_id}"
                ).apply()
            # Handle queue-specific context
            if queue := self.event.context.get("claim_queue"):
                queue_id = queue["dbid"]
                return LaunchModalEffect(
                    url=f"https://www.your-iframe-app.com?queue_id={queue_id}&source_url={current_url}",
                    target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
                    title=f"Your Iframe App - Queue {queue_id}"
                ).apply()
            # Handle general revenue page context
            if current_url.startswith("/revenue"):
                return LaunchModalEffect(
                    url=f"https://www.your-iframe-app.com?page=revenue&source_url={current_url}",
                    target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
                    title="Your Iframe App - Revenue"
                ).apply()
            # Return None when no relevant context - this will result in an empty effect list
            return None
    ```
##  Context Change Events 
Context change events are automatically triggered when users navigate between different URLs within Canvas. This feature allows your applications to react dynamically to the user's current context, providing relevant information and functionality based on where they are in the system.
###  Event Triggers 
Context change events are currently supported for revenue workflows and are triggered when:
  - A user navigates to a different URL within Canvas
  - The application is already open and running
  - The new URL is within the `/revenue` namespace
###  Context Data Structure 
When a context change event occurs, your `on_context_change()` method receives contextual information through `self.event.context`:
    ```python
    {
        "url": "/revenue/claims/123",           # Current URL that triggered the event
        "patient": {"id": "patient_key"},       # Patient information (when applicable)
        "user": {...},                          # User information
        "claim": {"id": "external_claim_id"},   # Claim context (for /revenue/claims/<id>)
        "claim_queue": {"dbid": "queue_id"}     # Queue context (for /revenue/queues/<id>)
    }
    ```
###  Supported URL Patterns 
URL Pattern| Context Provided| Description  
---|---|---  
`/revenue`| Base context only| General revenue page  
`/revenue/claims/<id>`| `claim` object with externally exposable ID| Specific claim details page  
`/revenue/queues/<id>`| `claim_queue` object with database ID| Specific queue management page  
###  Best Practices 
  1. **Always check for context existence** : Use safe dictionary access patterns to avoid KeyErrors
  2. **Handle multiple context types** : Your application may receive different types of context based on the URL
  3. **Return None appropriately** : When no relevant action is needed, return None to avoid unnecessary effects
###  Advanced Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class AdvancedRevenueApp(Application):
        def on_open(self) -> Effect | list[Effect]:
            return LaunchModalEffect(
                url="https://www.your-app.com/dashboard",
                target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
                title="Revenue Analytics"
            ).apply()
        def on_context_change(self) -> Effect | list[Effect] | None:
            current_url = self.event.context.get("url", "")
            patient = self.event.context.get("patient", {})
            user = self.event.context.get("user", {})
            # Build base parameters
            params = {
                "source_url": current_url,
                "user_id": user.get("id", ""),
                "patient_id": patient.get("id", "")
            }
            # Handle specific contexts
            if claim := self.event.context.get("claim"):
                params["claim_id"] = claim["id"]
                params["view"] = "claim_details"
                title = f"Revenue Analytics - Claim {claim['id']}"
            elif queue := self.event.context.get("claim_queue"):
                params["queue_id"] = queue["dbid"]
                params["view"] = "queue_management"
                title = f"Revenue Analytics - Queue {queue['dbid']}"
            elif current_url.startswith("/revenue"):
                params["view"] = "revenue_overview"
                title = "Revenue Analytics - Overview"
            else:
                # No relevant context for this application
                return None
            # Build query string
            query_string = "&".join(f"{k}={v}" for k, v in params.items() if v)
            return LaunchModalEffect(
                url=f"https://www.your-app.com/revenue?{query_string}",
                target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
                title=title
            ).apply()
    ```
In addition, your `CANVAS_MANIFEST.json` file must provide some information about your application. You reference your class in the "applications" section of the components so your application is registered in the app drawer on plugin installation.
This is also where you can define the title and icon that displays your app in the app drawer. The icon will be rendered at 48px by 48px, so should be square and simple enough to not lose detail at that size.
##  Application Scopes 
The `scope` attribute determines where your application is visible within Canvas. The following scopes are available:
Scope| Description  
---|---  
`patient_specific`| Visible only within a patient's chart in the app drawer  
`global`| Visible outside of patient charts in the app drawer  
`full_chart`| Displayed as a tab in the patient chart navigation menu alongside Chart and Profile  
`provider_menu_item`| Displayed as a menu item in the provider menu  
`portal_menu_item`| Displayed as a menu item in the patient portal  
`provider_companion`| Visible on the [Provider Companion](/sdk/companion/) main page (legacy, use `provider_companion_global` for new apps)  
`provider_companion_global`| In the app launcher on the [Provider Companion](/sdk/companion/) main page  
`provider_companion_patient_specific`| As a tab on a patient's page in the [Provider Companion](/sdk/companion/)  
`provider_companion_note_specific`| As a tab within an opened note in the [Provider Companion](/sdk/companion/)  
###  Full Chart Scope 
Applications with the `full_chart` scope appear as navigation tabs at the top of the patient chart, alongside the default "Chart" and "Profile" tabs. This is ideal for building comprehensive patient-level views or dashboards.
    ```json
    {
      "class": "my_plugin.apps.analytics:PatientAnalytics",
      "name": "Analytics",
      "description": "Patient analytics dashboard",
      "icon": "/assets/analytics-icon.png",
      "scope": "full_chart"
    }
    ```
##  Provider Companion Applications 
Provider companion applications run in the Canvas provider companion — a mobile-optimized, provider-facing surface. They use the `Application` handler with one of three companion scopes (`provider_companion_global`, `provider_companion_patient_specific`, `provider_companion_note_specific`) declared in the manifest. The legacy `provider_companion` scope continues to work and is treated the same as `provider_companion_global`.
See [Provider Companion](/sdk/companion/) for the full guide — scope-by-scope examples, event context, code sharing across scopes, originating commands from a note, modal dismissal, and mobile UX guidance.
##  Embedded Applications 
Note Applications (tabs inside a note), Scheduling Applications (which replace the built-in scheduling modal), and Docked Applications (a persistent pane pinned to a window edge) are **embedded applications** — handler-based applications that render inside a specific Canvas surface rather than appearing in the app drawer. They are declared under `handlers` (not `applications`), take no `scope` or `icon`, and create no application record.
See [Embedded Applications](/sdk/handlers-embedded-applications/) for the full guide.
##  Panel Display 
If you want to increase your application's visibility and display it alongside other panel buttons (instead of in the applications drawer), you can add the `show_in_panel` attribute. If you've added more than one application to that panel, you can set their priorities using the `panel_priority` attribute.
For security reasons you also need to specify the domains that will be loaded within the iframe, or they will not be rendered. For more info on the format of the `url_permissions` field, check the [Additional Configuration](/sdk/layout-effect/#additional-configuration) for `LaunchModalEffect`.
Here's what your `CANVAS_MANIFEST.json` might look like:
    ```json
    {
      "sdk_version": "0.1.4",
      "plugin_version": "0.0.1",
      "name": "my_application",
      "description": "This is a very nice application",
      "url_permissions": [
        {
          "url": "https://example.com/",
          "permissions": ["ALLOW_SAME_ORIGIN", "MICROPHONE", "SCRIPTS", "CAMERA", "CLIPBOARD_READ", "CLIPBOARD_WRITE"]
        }
      ],
      "components": {
        "handlers": [],
        "applications": [
          {
            "class": "my_application.apps.iframe:IFrameApp",
            "name": "My Application",
            "description": "Test App for patients",
            "icon": "/assets/cappuccino.png",
            "scope": "patient_specific",
            "show_in_panel": true,
            "panel_priority": 100
          }
        ],
        "commands": [],
        "content": [],
        "effects": [],
        "views": []
      },
      "variables": [],
      "tags": {},
      "references": [],
      "license": "",
      "diagram": false,
      "readme": "./README.md"
    }
    ```
##  Opening an Application on Load 
You can configure an application to open **automatically** , without the user clicking its icon, by enabling the **Open on load** setting for that application in your instance settings.
To enable it, go to the Plugins_IO > Applications section of your instance settings (`/admin/plugin_io/application/`), open the application you want, check **Open on load** , and save. If you don't have access to this setting, reach out to Canvas Support.
Behavior depends on the application's scope:
Scope| When it opens  
---|---  
`global`| Automatically when the app shell first loads.  
`patient_specific`| Automatically when a patient chart is opened.  
This is an instance-level setting configured per application in your instance settings. It is **not** part of `CANVAS_MANIFEST.json`, so the value you set is preserved when the plugin is reinstalled or updated.
> **Warning:** **Enable Open on load for at most one application per scope.** There is no priority or ordering logic for this setting, and no constraint preventing multiple applications in the same scope from being flagged. If more than one application in the same scope (for example, two `patient_specific` apps) has Open on load enabled, all of them will attempt to open, resulting in unpredictable behavior. Make sure only one application per scope is set to open on load.
> **Note:** This is distinct from a Note Application's [`open_by_default()`](/sdk/handlers-embedded-applications/#opening-by-default), which controls which **tab** is active when a note is viewed. **Open on load** controls whether a `global` or `patient_specific` application opens automatically on app/chart load.
##  Notification Badges 
You can display a notification badge — a small count — on a `global`, `patient_specific`, or `provider_menu_item` application: on the icon in the app drawer or panel (`global` / `patient_specific`, the latter when the application sets `show_in_panel`), or next to the label in the provider menu (`provider_menu_item`). A badge is useful for surfacing how many items are waiting for attention, such as unread messages or open tasks. Applications in other scopes (`full_chart`, `portal_menu_item`, and the Provider Companion scopes) do not display badges.
###  Initial count on load 
Override `compute_notification_badge()` on your `Application` handler to provide the count shown when Canvas loads applications. Return an integer to show a badge, or `None` (the default) to show no badge. A count of `0` shows no badge.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    from canvas_sdk.v1.data.task import Task, TaskStatus
    class InboxApp(Application):
        def on_open(self) -> Effect | list[Effect]:
            return LaunchModalEffect(
                url="https://www.your-app.com/inbox",
                title="Inbox",
            ).apply()
        def compute_notification_badge(self) -> int | None:
            """Return the badge count shown on the icon when applications load."""
            staff_id = self.event.context.get("staff", {}).get("id")
            if not staff_id:
                return None
            return Task.objects.filter(assignee__id=staff_id, status=TaskStatus.OPEN).count()
    ```
When the application is rendered on a patient chart (`patient_specific` scope), the event context also carries the patient, so you can compute a count specific to the staff member _and_ the patient they are viewing:
    ```python
    from canvas_sdk.v1.data.task import Task, TaskStatus
    def compute_notification_badge(self) -> int | None:
        staff_id = self.event.context.get("staff", {}).get("id")
        patient_id = self.event.context.get("patient", {}).get("id")
        if not (staff_id and patient_id):
            return None
        return Task.objects.filter(
            assignee__id=staff_id, patient__id=patient_id, status=TaskStatus.OPEN
        ).count()
    ```
The badge event context contains:
Key| Description  
---|---  
`staff`| A dict with the staff `id` and `type` (present for staff-facing apps).  
`patient`| A dict with the patient `id` and `type` (present on a patient chart).  
> **Note:** Note Applications (`NoteApplication`) do not support notification badges.
###  Live updates 
To change the count after load — for example, in response to a new task or message — emit an `ApplicationNotificationBadge` effect from any event handler. The badge updates in real time without the user reloading the page. See the [Application Notification Badge](/sdk/effect-application-notification-badge/) effect for details.

# Base Handler

Source: https://docs.canvasmedical.com/sdk/handlers-basehandler/

The `BaseHandler` is the simplest of all handlers. Specify which events you are interested in, then provide the code to execute when one of those events is emitted. All the [handlers](/sdk/handlers/) inherit from `BaseHandler`, and many of yours will too.
##  Handling Events With `BaseHandler`
To create a class that responds to one or more events, inherit from `BaseHandler`, set the `RESPONDS_TO` constant, and implement the `compute()` method.
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class MyEventHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
        def compute(self):
            # Your code goes here!
            return []
    ```
You can respond to one event, or several. To respond to multiple events, set `RESPONDS_TO` to a list of [event types](/sdk/events/).
    ```python
    # Respond when tasks are created:
    RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
    # Respond when tasks are created OR updated:
    RESPONDS_TO = [
        EventType.Name(EventType.TASK_CREATED),
        EventType.Name(EventType.TASK_UPDATED),
    ]
    ```
The `compute()` method must return a list of [Effects](/sdk/effects/). That list can be empty, of course. You have access to event information with `self.event`, `self.target`, and`self.context`, as well as configuration information for your plugin with `self.secrets` and for the running instance with `self.environment`. You can use our [Data Module](/sdk/data/) to retrieve additional information at runtime.

# CronTask

Source: https://docs.canvasmedical.com/sdk/handlers-crontask/

You can write a handler that subclasses `CronTask` to execute code on a schedule. You might use this to automate reporting on task performance (every hour, send the number of tasks created during the previous hour, and the number of tasks completed during the previous hour), to send birthday wishes to your patients (at 7am every morning, find patients born on this day and send them an email wishing them a happy birthday), or to send customized appointment reminders (every hour, find appointments that start on this hour the following day and send the patients of those appointments a message that says "Dr. X is looking forward to seeing you at (location) at (time)").
##  Example 
This example `CronTask` shows an extremely basic example that just logs the time. You can see the critical pieces here:
  - Subclass `CronTask`
  - Set your `SCHEDULE` with a cron string
  - Implement an `execute` method with the code you want to schedule to run, returning a list containing any effects you want to return, or an empty list if you do not wish to return any effects.
    ```python
    from canvas_sdk.handlers.cron_task import CronTask
    from canvas_sdk.effects import Effect
    from logger import log
    class LogTheTime(CronTask):
        # A cron string.
        #           ┌───────────── minute (0 - 59)
        #           │ ┌───────────── hour (0 - 23)
        #           │ │ ┌───────────── day of the month (1 - 31)
        #           │ │ │ ┌───────────── month (1 - 12)
        #           │ │ │ │ ┌───────────── day of the week (0 - 6) (Sunday to Saturday)
        #           │ │ │ │ │
        #           │ │ │ │ │
        #           │ │ │ │ │
        SCHEDULE = "* * * * *"  # Run every minute, which is the most frequently something can run.
        def execute(self) -> list[Effect]:
            # The current timestamp can be found as an iso8601 string in
            # `self.target`
            log.info(f"The current time is {self.target}")
            # We don't need to return any effects
            return []
    ```
###  Output 
Here's what this scheduled task would output in the logs:
`INFO 2024-07-18 18:47:00,000 The current time is 2024-07-18T18:47:00.000000+00:00`

# Embedded Applications

Source: https://docs.canvasmedical.com/sdk/handlers-embedded-applications/

Embedded applications render **inside a specific Canvas surface** (a tab within a note, the scheduling modal, or a pane pinned to a window edge) rather than as an icon in the app drawer. They are ordinary [handlers](/sdk/handlers-basehandler/): you subclass a base class, register it under `handlers` in your `CANVAS_MANIFEST.json`, and Canvas renders it in the appropriate surface.
There are three kinds:
Base class| Surface  
---|---  
`NoteApplication`| A tab within a patient's note  
`SchedulingApplication`| Replaces the built-in scheduling modal at every entry point  
`DockedApplication`| A persistent pane pinned to a window edge, always visible  
##  How embedded applications work 
Embedded applications are [handlers](/sdk/handlers-basehandler/). You build one by subclassing `NoteApplication`, `SchedulingApplication`, or `DockedApplication` and registering it under `handlers` in your `CANVAS_MANIFEST.json` — everything else is inherited from that parent class.
Because the parent class defines the behavior, there's very little to configure:
  - The **surface** comes from the class you inherit — `NoteApplication` renders as a tab in a note, `SchedulingApplication` replaces the scheduling modal, and `DockedApplication` pins a persistent pane to a window edge. You don't set a `scope` or an `icon`.
  - Canvas renders Note and Scheduling Applications **on demand** : when a note opens or a scheduling action is triggered, Canvas asks which embedded application is installed for that surface, then renders what your handler returns. A Docked Application is the exception: it stays mounted at all times instead of rendering on demand. None of the three are persisted as drawer applications, so they don't appear in the app drawer or under Plugins_IO > Applications.
  - If no embedded application is installed for a surface, Canvas falls back to its built-in behavior — an unmodified note, or the built-in scheduling modal.
Since the surface and scope are inherited from the parent class, register these under `handlers` rather than `applications`.
##  Note Applications 
Note Applications appear as tabs within a patient's note, allowing you to embed custom interfaces directly in the clinical documentation workflow.
###  Implementing a Note Application 
To create a Note Application, your handler class should inherit from `NoteApplication` and define the following class attributes:
Attribute| Description  
---|---  
`NAME`| (Required) The display title shown on the tab (supports emojis)  
`IDENTIFIER`| (Required) A unique key for the application (recommended format: `plugin_name__app_name`)  
`PRIORITY`| (Optional) Controls tab order — lower values appear first. Defaults to `0`  
> **Tip:** If your Note Application is named "Note", it may cause confusion with the built-in Note tab. Users can rename the built-in tab by updating the Constance Config setting `NOTE_BODY_TAB_LABEL` in your instance Settings, to avoid duplication.
Your class must implement the `on_open()` method, which is called when the user clicks on the tab. This method should return an `Effect` or list of `Effect`s, typically a `LaunchModalEffect` with `target` set to `LaunchModalEffect.TargetType.NOTE`
> **⚠️ Important** If you have an existing plugin that overrides `handle()`, it will continue to work. However, `handle()` is deprecated — migrate to `on_open()` at your earliest convenience.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import NoteApplication
    class PatientIntakeApp(NoteApplication):
        """Note application for patient intake workflow."""
        NAME = "📋 Patient Intake"
        IDENTIFIER = "my_plugin__patient_intake"
        def on_open(self) -> Effect | list[Effect]:
            """Launch the intake form when the tab is clicked."""
            note_id = self.event.context.get("note_id")
            patient_id = self.event.context.get("patient", {}).get("id")
            return LaunchModalEffect(
                target=LaunchModalEffect.TargetType.NOTE,
                content="<html>Your form HTML here</html>",
                title="Patient Intake Form"
            ).apply()
    ```
![note applications](/assets/images/note-application-tabs.png)
###  Manifest Configuration 
Register your Note Application under the `handlers` section of your `CANVAS_MANIFEST.json`. There is no `scope` or `icon` — the note tab is driven by the `NoteApplication` base class and the `NAME`/`IDENTIFIER` class attributes.
    ```json
    {
      "components": {
        "handlers": [
          {
            "class": "my_plugin.apps.intake:PatientIntakeApp",
            "description": "In-note patient intake tab."
          }
        ]
      }
    }
    ```
###  Context and Event Data 
Both `on_open()` and `handle()` have access to context data through `self.event.context`:
Key| Description  
---|---  
`note_id`| The database ID of the current note  
`note`| A dict containing the note's external `id` (UUID)  
`patient`| A dict containing the patient's `id`  
`user`| Information about the current user  
####  `on_open()` — recommended 
When using `on_open()`, the patient is available through `self.event.context`:
    ```python
    from canvas_sdk.effects import Effect
    def on_open(self) -> Effect | list[Effect]:
        note_id = self.event.context.get("note_id")
        patient_id = self.event.context.get("patient", {}).get("id")
        ...
    ```
`self.event.target.id` contains the application identifier used internally for routing, not the patient.
####  `handle()` — deprecated 
When using the deprecated `handle()`, `self.event.target.id` is automatically set to the patient UUID before `handle()` is called, preserving the original behavior that old plugins relied on:
    ```python
    from canvas_sdk.effects import Effect
    def handle(self) -> list[Effect]:
        patient_id = self.event.target.id  # backfilled from patient context
        ...
    ```
> **Note:** This backfilling only happens when `handle()` is called. Plugins that override `on_open()` directly should read the patient from `self.event.context` as shown above.
Property| `on_open()`| `handle()` (deprecated)  
---|---|---  
`self.event.target.id`| Application identifier (for routing)| Patient UUID (backfilled)  
`self.event.context["patient"]["id"]`| Patient UUID| Patient UUID  
`self.event.actor`| Authenticated user| Authenticated user  
###  Controlling Visibility 
You can control when your Note Application tab is visible by overriding the `visible()` method. This method has access to the same context and event data as `on_open()`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import NoteApplication
    class ConditionalIntakeApp(NoteApplication):
        NAME = "📋 Intake"
        IDENTIFIER = "my_plugin__conditional_intake"
        def visible(self) -> bool:
            """Only show for specific conditions."""
            # Add your visibility logic here
            return True
        def on_open(self) -> Effect | list[Effect]:
            return LaunchModalEffect(
                target=LaunchModalEffect.TargetType.NOTE,
                content="<html>Form content</html>",
                title="Intake"
            ).apply()
    ```
###  Opening by Default 
You can make a Note Application tab open automatically when a note is first viewed by overriding `open_by_default()`. If multiple applications return `True`, the first one (by priority order) will be opened.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import NoteApplication
    class AutoOpenApp(NoteApplication):
        NAME = "📋 Intake"
        IDENTIFIER = "my_plugin__auto_open_intake"
        def open_by_default(self) -> bool:
            """Open automatically when the note is viewed."""
            return True
        def on_open(self) -> Effect | list[Effect]:
            return LaunchModalEffect(
                target=LaunchModalEffect.TargetType.NOTE,
                content="<html>Form content</html>",
                title="Intake"
            ).apply()
    ```
###  Tab Ordering 
You can control the order in which Note Application tabs appear by setting the `PRIORITY` class attribute. Tabs are sorted in ascending order, so lower values appear first. The default is `0`.
    ```python
    from canvas_sdk.handlers.application import NoteApplication
    class HighPriorityApp(NoteApplication):
        NAME = "First Tab"
        IDENTIFIER = "my_plugin__first"
        PRIORITY = 1
    class LowPriorityApp(NoteApplication):
        NAME = "Second Tab"
        IDENTIFIER = "my_plugin__second"
        PRIORITY = 10
    ```
> **Note:** Note Applications do not support [notification badges](/sdk/handlers-applications/#notification-badges).
##  Scheduling Applications 
Scheduling Applications replace the built-in scheduling modal throughout Canvas. When you install a plugin with a scheduling application, it takes over all scheduling entry points: the schedule page, patient chart, calendar drag-and-drop, calendar reschedule, and note reschedule flows.
###  Implementing a Scheduling Application 
To create a Scheduling Application, your handler class should inherit from `SchedulingApplication` and define two required class attributes:
Attribute| Description  
---|---  
`NAME`| The display title shown in the modal  
`IDENTIFIER`| A unique key for the application (recommended format: `plugin_name__app_name`)  
Your class must implement the `on_open()` method, which is called when a scheduling action is triggered. This method should return an `Effect` or list of `Effect`s, typically a `LaunchModalEffect`.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import SchedulingApplication
    class CustomScheduler(SchedulingApplication):
        """Scheduling application for custom appointment booking."""
        NAME = "Schedule Appointment"
        IDENTIFIER = "my_plugin__scheduler"
        def on_open(self) -> Effect | list[Effect]:
            """Launch the scheduling form when triggered."""
            patient = self.event.context.get("patient", {})
            provider = self.event.context.get("provider", {})
            start = self.event.context.get("start", "")
            mode = self.event.context.get("mode", "schedule")
            return LaunchModalEffect(
                url=f"https://scheduler.example.com/book?patient={patient.get('id', '')}&provider={provider.get('id', '')}&start={start}&mode={mode}",
                title="Schedule Appointment"
            ).apply()
    ```
###  Context Data 
When `on_open()` is called, scheduling context is available through `self.event.context`. The available keys depend on which entry point triggered the scheduling action.
####  Entity Objects 
Entities are delivered as `{"id": <external id>}` objects, resolvable with the conventional `.objects.get(id=...)`:
Field| Resolves To| Value| Available From  
---|---|---|---  
`patient`| [Patient](/sdk/data-patient/#patient)| `{"id": <patient id>}`| Patient chart, reschedule flows  
`provider`| [Staff](/sdk/data-staff/#staff)| `{"id": <staff id>}`| Calendar, patient chart  
`location`| [PracticeLocation](/sdk/data-practicelocation/#practicelocation)| `{"id": <practice location id>}`| Current location context  
`appointment`| [Appointment](/sdk/data-appointment/#appointment)| `{"id": <appointment id>}`| Reschedule flows  
`note`| [Note](/sdk/data-note/#note)| `{"id": <note id>}`| Note reschedule flow  
####  Scalar Values 
Key| Description  
---|---  
`start`| ISO-8601 datetime of the selected slot (all entry points)  
`end`| ISO-8601 datetime for the slot end (calendar drag-and-drop only)  
`duration`| Slot length in minutes (reschedule flows only). Either `end` or `duration` is present, never both  
`mode`| One of `schedule`, `reschedule`, or `followup`  
`origin`| The launching surface: `schedule_page`, `patient_chart`, `calendar`, `calendar_reschedule`, or `note_reschedule`  
When `end` is not provided, derive it from `start + duration`.
####  Origins 
`origin` tells you which surface launched the scheduling action, which in turn determines the `mode` and whether the slot length arrives as `end` or `duration`:
`origin`| Launching surface| `mode`| Slot length  
---|---|---|---  
`schedule_page`| **New appointment** from the schedule page (no patient context)| `schedule` or `followup`| neither (`start` only)  
`patient_chart`| **New appointment** from a patient's chart| `schedule` or `followup`| neither (`start` only)  
`calendar`| Drag-and-drop on the calendar to create a slot| `schedule`| `end`  
`calendar_reschedule`| Rescheduling an existing appointment from the calendar| `reschedule`| `duration`  
`note_reschedule`| Rescheduling an appointment from within a note| `reschedule`| `duration`  
Which entities accompany each origin is shown in the Entity Objects table's "Available From" column above — for example, `patient_chart` and the reschedule flows include a `patient`, while `schedule_page` and `calendar` do not.
###  Manifest Configuration 
Register your Scheduling Application under the `handlers` section of your `CANVAS_MANIFEST.json`. There is **no** `scope` or `icon` — inheriting from `SchedulingApplication` is what tells Canvas to use it as the scheduling-modal override.
    ```json
    {
      "components": {
        "handlers": [
          {
            "class": "my_plugin.apps.scheduler:CustomScheduler",
            "description": "Custom appointment scheduling that overrides the built-in modal."
          }
        ]
      }
    }
    ```
When installed, this application replaces the built-in scheduling modal. If no scheduling application is installed, the existing built-in modal continues to work unchanged.
##  Docked Applications 
A Docked Application mounts as a persistent **docked pane** pinned to a window edge. It stays in place as the user moves between pages, including between a patient chart and global pages, rather than opening fresh each time.
Reach for a docked pane when a surface needs to follow the user instead of being opened and re-opened: a telephony or messaging bar that has to survive navigation mid-call, a live worklist the user works through while moving between charts, or an ambient scribe that keeps recording as the clinician moves around a note. Because the pane stays mounted, whatever state it holds survives that navigation, whether that's a scroll position, a half-filled form, or an open connection. A modal or an overlay cannot do this, since both are torn down when the page changes.
###  Implementing a Docked Application 
A Docked Application is a handler that inherits from `DockedApplication`, declares the pane's placement as class attributes, and implements `on_open()` to mount the pane's content:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import DockedApplication, DockEdge
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data.task import Task, TaskStatus
    class TaskDock(DockedApplication):
        """Docked application that keeps the signed-in user's open tasks on screen."""
        NAME = "My Tasks"
        IDENTIFIER = "my_plugin__task_dock"
        DOCK_EDGE = DockEdge.RIGHT
        DOCK_SIZE = "320px"
        def on_open(self) -> Effect | list[Effect]:
            """Mount the docked pane's content."""
            user_id = self.event.context.get("user", {}).get("id")
            tasks = Task.objects.filter(assignee__id=user_id, status=TaskStatus.OPEN).order_by("due")
            return LaunchModalEffect(
                target=LaunchModalEffect.TargetType.DOCKED_PANE,
                content=render_to_string("templates/task_dock.html", {"tasks": tasks}),
                title="My Tasks",
            ).apply()
    ```
The pane's markup lives in a Django template in your plugin rather than in a Python string, rendered by [`render_to_string`](/sdk/layout-effect/#custom-html-and-django-templates). Here that template is `templates/task_dock.html`:
    ```html
    <!DOCTYPE html>
    <html>
      <head>
        <title>My Tasks</title>
      </head>
      <body>
        <h1>My Tasks</h1>
        <ul>
          {% for task in tasks %}
            <li>{{ task.title }} (due {{ task.due }})</li>
          {% endfor %}
        </ul>
      </body>
    </html>
    ```
`on_open()` returns a [`LaunchModalEffect`](/sdk/layout-effect/#modals) with `target` set to `LaunchModalEffect.TargetType.DOCKED_PANE`. That target is what mounts the effect's rendered `content` (or a `url`) in the pane rather than in a modal. Canvas draws no chrome around a docked pane, so `title` is never displayed: it becomes the pane's accessible name for screen readers.
There is no app drawer entry that opens a docked pane and no Canvas-provided control that closes or minimizes it. For the staff who get one, the pane is simply on screen for the whole session, and which staff those are is the plugin's decision: see Controlling who gets a pane. The pane's own content can remove itself at runtime, which is how a plugin offers its own collapse or close control. See Sizing, Resizing, and Collapsing.
####  Class attributes 
Attribute| Required| Description  
---|---|---  
`NAME`| Required| The display title for the pane  
`IDENTIFIER`| Optional| A unique key for the application. When omitted, the identifier defaults to one derived automatically from the class's module and name. Set it explicitly in the recommended `plugin_name__app_name` format to give the application a stable, readable identifier.  
`DOCK_EDGE`| Required| Which window edge to pin the pane to, given as a `DockEdge` value  
`DOCK_SIZE`| Required| The pane's initial size and the initial ceiling for the plugin's own resize requests, as a CSS length string (for example, `320px`). See Sizing, Resizing, and Collapsing.  
`PRIORITY`| Optional| An integer controlling stacking order when multiple panes share an edge — lower values sit nearer the window edge. Defaults to `0`. See Multiple Docked Panes.  
####  DockEdge 
`DockEdge` is an enum of the four window edges a pane can be pinned to.
Name| Value| Edge to pin to  
---|---|---  
`LEFT`| `left`| Left edge of the window  
`RIGHT`| `right`| Right edge of the window  
`TOP`| `top`| Top edge of the window  
`BOTTOM`| `bottom`| Bottom edge of the window  
####  Controlling who gets a pane 
A docked pane is not all-or-nothing across an instance. Override `visible()` to decide, per staff member, whether the pane exists for them at all:
    ```python
    def visible(self) -> bool:
        """Only dock the pane for the care coordination team."""
        staff_id = self.event.context.get("user", {}).get("id")
        return Staff.objects.filter(id=staff_id, teams__name="Care Coordination").exists()
    ```
Returning `False` means that user gets no pane: Canvas never calls `on_open()` for them and sends them no context changes. `visible()` defaults to `True`, so a Docked Application that does not override it docks for everyone.
Two things to know about when this runs. Canvas asks for docked applications once as the EHR shell loads, so `visible()` is evaluated then and not again as the user navigates inside the shell. A change in the answer therefore takes effect on that user's next full page load. And the context `visible()` receives holds only `scope` and `user`, with no `patient` or `note`, because the question being asked is which panes this session gets rather than what is on screen. Gate on the staff member, or on anything you can look up from them, rather than on what they are currently viewing.
Do not use `on_open()` for this. Returning no docked-pane effect from `on_open()` also leaves the pane unmounted, but panes are mounted once per session and never retried, so the pane stays gone for the rest of the session with no way back.
###  Pane Context and Navigation 
Like other embedded applications, a Docked Application reads request context from `self.event.context`. It receives that context twice over: once when the pane first mounts, through `on_open()`, and again on each navigation, through `on_context_change()`. Both entry points get the same three keys:
Key| Value| Description  
---|---|---  
`url`| `str`| The path of the Canvas page the user is on. Always one of the pages a pane sees.  
`user`| `{"id": str, "type": str}`| The signed-in user, always present. `id` is the [Staff](/sdk/data-staff/#staff) id; `type` is the name of the person record behind the login, which is `Staff` in the EHR.  
`patient`| `{"id": str}`| The patient whose chart is open. Present only on a `/patient/<patient id>` path and absent entirely elsewhere, so read it as `self.event.context.get("patient", {})`.  
On a patient chart the whole context looks like this:
    ```python
    {
        "url": "/patient/b80b1cdc2e6a4aca90ccebc02e683f35",
        "user": {"id": "5eede137ecfe4124b8b773040e33be14", "type": "Staff"},
        "patient": {"id": "b80b1cdc2e6a4aca90ccebc02e683f35"},
    }
    ```
On the schedule, where no patient is in the path, the `patient` key is simply not there:
    ```python
    {
        "url": "/schedule",
        "user": {"id": "5eede137ecfe4124b8b773040e33be14", "type": "Staff"},
    }
    ```
####  `on_open()`
Fires once, when the pane mounts, and returns the effect that gives the pane its content:
    ```python
    def on_open(self) -> Effect | list[Effect]:
        url = self.event.context.get("url")
        user_id = self.event.context.get("user", {}).get("id")
        patient_id = self.event.context.get("patient", {}).get("id")
        ...
    ```
####  `on_context_change()`
Fires on each navigation after that, with the new `url` and the `patient` derived from the new path. This is how a pane stays context-aware as the user moves around Canvas.
It defaults to a no-op, so a pane that does not override it keeps whatever it last rendered. Override it to return the plugin's own content or hosted URL, rebuilt from the new context, such as a hosted URL that carries the new patient id:
    ```python
    def on_context_change(self) -> Effect | list[Effect]:
        patient_id = self.event.context.get("patient", {}).get("id", "")
        return LaunchModalEffect(
            target=LaunchModalEffect.TargetType.DOCKED_PANE,
            url=f"https://task-dock.example.com/panel?patient={patient_id}",
        ).apply()
    ```
The pane's document reloads only when `on_context_change()` returns a different `url` or `content`. Returning the same `url` or `content` as before leaves the pane's current document in place, preserving its scroll position and state, and so does returning no effect at all (`None` or an empty list). Whether to reload is your plugin's choice.
####  Pages a pane sees 
`url` is the path of the Canvas page around the pane, never the URL loaded inside the pane's own iframe. A pane navigating its own document is invisible to Canvas and produces no context change, and neither does a change to the page URL's hash.
Docked panes mount in the EHR shell, so `url` is always one of the paths that shell routes. Some of these pages are gated by permission or by a feature flag, so which of them a given user reaches will vary:
Path| Page  
---|---  
`/patient/<patient id>`| A patient's chart, including its sub-paths. The only path that carries a `patient` in context  
`/schedule`| The schedule calendar  
`/patients`| The patient list  
`/panel`| A patient panel  
`/populations`| Population health  
`/campaigns`| Campaigns  
`/revenue`| Revenue and claims  
`/data-integration`| Data integration  
`/questionnaire-builder`| The questionnaire builder  
`/application`| A full-page plugin application  
`/403`| Permission denied  
Everything else on the domain sits outside that shell, including `/admin`, `/login`, `/app/...`, `/companion/...` and `/plugin-io/...`. Moving to one of those is a full page load rather than a navigation: the pane is not on screen while the user is there, and returning to the EHR mounts it again from scratch, so `on_open()` fires rather than `on_context_change()`.
The patient portal is outside the shell as well, so a docked pane cannot appear there. A Docked Application is a staff-facing surface only.
Because the pane stays mounted across every navigation inside the shell, it keeps its state there instead of being recreated like a modal or overlay that opens and closes.
###  Multiple Docked Panes 
Docked panes stack rather than being limited to one per edge. Each edge holds up to two panes. When an edge already holds its two panes, an additional pane for that edge is not displayed — it is ignored rather than raising an install-time error.
Panes sharing an edge share a single track, and they split it evenly. On a left or right edge they stack top to bottom, each as wide as the track; on a top or bottom edge they sit side by side, each as tall as it. So two panes on one edge each get half the length of that edge, and the edge itself is only as thick as the larger of their two `DOCK_SIZE` values, since those sizes are alternatives rather than additions.
Which pane comes first is decided by priority: the lower `PRIORITY` value goes first, which means the top of the stack on a left or right edge and the left-hand position on a top or bottom edge. Panes with equal priority are ordered by their identifier. This mirrors the way the `PRIORITY` class attribute orders Note Application tabs. To get a predictable order, set an explicit `PRIORITY` on each pane, and set an explicit `IDENTIFIER` rather than relying on the auto-derived one.
Panes cannot crowd Canvas out of its own window. The left and right panes together take up at most half the window's width, and the top and bottom panes together at most half its height. If the panes on one of those pairs would exceed their half, all of them are scaled down in proportion rather than any one being dropped.
###  Sizing, Resizing, and Collapsing 
`DOCK_SIZE` sets the pane's initial size — its width on the `LEFT` and `RIGHT` edges, its height on the `TOP` and `BOTTOM` edges — and the initial ceiling for the plugin's own resize requests. The user and the plugin resize the pane under different rules.
A user can resize a pane by dragging its edge or with the keyboard arrow keys, using the standard splitter the pane exposes. A user resize can make the pane larger or smaller than `DOCK_SIZE`: it stops at 48px, and at the half-the-window limit described above, but is not otherwise bound by `DOCK_SIZE`. The size a user drags to becomes the pane's new ceiling, replacing `DOCK_SIZE`, and is stored in the browser (`localStorage`) keyed by the pane's identifier, so it survives page reload and navigation. Once a user has resized a pane, that persisted size takes precedence on future loads, so changing `DOCK_SIZE` in a later plugin version does not affect panes a user has already resized, until the stored size is cleared.
There is no host-provided control to close or minimize the pane. A plugin can, however, resize or collapse its own pane from inside its iframe (for example, by collapsing it to a thin rail). A plugin's own resize can shrink the pane freely, down to a thin rail. It cannot grow the pane past the current ceiling: a request at or above the ceiling is clamped to the ceiling rather than applied as given, so a plugin restores the pane to its full (ceiling) size by requesting any value at or above it. A plugin-driven resize is not bound by the 48px floor that applies to user resizing.
A pane is removed only when the plugin's own content requests it, by posting the same `CLOSE_MODAL` message that applications use to dismiss modals. See [Closing Modals from Applications](/sdk/layout-effect/#closing-modals-from-applications) for the full mechanism. Once removed, nothing re-mounts the pane short of a page reload.
A docked pane cannot navigate the host application directly; navigation is issued through a redirect effect. It does not reset the session idle-logout timer.
###  Manifest Configuration 
Register your Docked Application under the `handlers` section of your `CANVAS_MANIFEST.json`. As with Note and Scheduling Applications, there is **no** `scope` or `icon` — inheriting from `DockedApplication` is what tells Canvas to mount it as a docked pane.
    ```json
    {
      "components": {
        "handlers": [
          {
            "class": "my_plugin.apps.task_dock:TaskDock",
            "description": "Open task list docked to the right edge."
          }
        ]
      }
    }
    ```

# Payment Processors

Source: https://docs.canvasmedical.com/sdk/handlers-payment-processors/

The Canvas SDK provides a way to define custom payment processors that enables Canvas to:
  - Handle payment-related workflows within the platform
  - Integrate with third-party payment providers
  - Manage payment methods for patients
Custom payment processors enable flexibility, allowing developers to replace Stripe with other payment providers. Currently, only credit card payment processors are supported.
##  Payment Processor Handler 
All payment processors are implemented as subclasses of the abstract `PaymentProcessor` handler. This defines the base contract for:
  - Selecting a processor
  - Charging payments
  - Listing, adding, and removing payment methods
You can find it in:
    ```python
    from canvas_sdk.handlers.payment_processors.base import PaymentProcessor
    ```
`PaymentProcessor` is an abstract base that wires up event handling but does not define the methods a plugin needs to implement. You should not subclass it directly — instead, extend one of its typed subclasses. Currently the only supported type is `CardPaymentProcessor`, which is where the methods you need to define are declared.
* * *
##  CardPaymentProcessor 
If your custom processor deals with card payments, extend the `CardPaymentProcessor`, which provides additional structure.
    ```python
    from canvas_sdk.handlers.payment_processors.card import CardPaymentProcessor
    ```
In the plugin, this is implemented as:
    ```python
    from canvas_sdk.handlers.payment_processors.card import (
        CardPaymentProcessor,
    )
    class PayTheoryPaymentProcessor(CardPaymentProcessor):
        ...  # Your implementation here
    ```
* * *
##  Defining a `CardPaymentProcessor`
When implementing a `CardPaymentProcessor`, you must define how Canvas should display forms for adding and charging cards, how to process those payments, and how to manage saved payment methods.
In order to implement a `CardPaymentProcessor`, you should override and implement the following methods grouped into three main categories:
  - Displaying forms
  - Charging a card
  - Managing payment methods
###  Displaying Forms 
The forms you return via [`PaymentProcessorForm`](/sdk/payment-processor-effect/#paymentprocessorform) are rendered directly as **inner HTML** within the Canvas application. These forms must define a small contract of JavaScript behaviors to allow Canvas to communicate with them.
These methods define the HTML content that will be rendered inside Canvas to collect card data for payments or adding new cards. They must comply with the Form Workflow.
These forms render wherever Canvas collects a card payment or manages saved payment methods, including:
  - the **provider UI** — the Revenue module and the patient profile payment/insurance area
  - the **Patient Portal** — when a patient makes a payment or manages their saved cards
####  Payment Form 
Triggered when a user selects the credit card payment option. This method should return the HTML form used to collect and tokenize the payment details.
    ```python
    from canvas_sdk.effects.payment_processor import PaymentProcessorForm
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    def payment_form(self, patient: Patient | None = None) -> PaymentProcessorForm:
        content = render_to_string("templates/payment_form.html")
        return PaymentProcessorForm(intent="pay", content=content)
    ```
* * *
####  Add Card Form 
Triggered when a user initiates the process of adding a new card to a patient's saved payment methods. This method should return the HTML form used to collect and tokenize the new card information.
    ```python
    from canvas_sdk.effects.payment_processor import PaymentProcessorForm
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    def add_card_form(self, patient: Patient | None = None) -> PaymentProcessorForm:
        content = render_to_string(
            "templates/add_card_form.html",
            {"payor_id": self.api.get_default_payor_id()},
        )
        return PaymentProcessorForm(intent="add_card", content=content)
    ```
* * *
###  Charging a Card 
Handles the actual payment. This method is triggered after tokenization and is responsible for charging the card. It returns a [`CardTransaction`](/sdk/payment-processor-effect/#cardtransaction) effect describing the result of the charge:
    ```python
    from decimal import Decimal
    from typing import Any
    from canvas_sdk.effects.payment_processor import (
      CardTransaction,
      PaymentProcessorForm
    )
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    def charge(
        self,
        amount: Decimal,
        token: str,
        patient: Patient | None = None,
        **kwargs: Any
    ) -> CardTransaction:
        payload = {
            "token": token,
            "amount": int(amount * 100),
            "currency": "usd",
            "metadata": {"patient_id": patient.id},
        }
        result = self.api.charge(payload)
        return CardTransaction(
            transaction_id=result["transaction_id"],
            success=True,
            api_response=result,
        )
    ```
####  Additional Context 
The `charge` method accepts `**kwargs` which can contain additional context passed from the payment form. This is useful when you need to pass extra information from the tokenization response (e.g., payment method details, transaction metadata) to the charge handler.
The additional context is passed via the second argument of `setToken` in your form's JavaScript (see Form Workflow). Canvas processes the `additional_context` as follows:
Input Type| Example| Passed to `charge` as  
---|---|---  
JSON object string| `'{"key": "value"}'`| `key="value"` (unpacked as kwargs)  
`None`| `null`| `additional_context=None`  
Plain string| `"some text"`| `additional_context="some text"`  
JSON number string| `"123"`| `additional_context=123`  
JSON boolean string| `"true"`| `additional_context=True`  
Example using additional context:
    ```python
    from decimal import Decimal
    from typing import Any
    from canvas_sdk.effects.payment_processor import (
      CardTransaction,
      PaymentProcessorForm
    )
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    def charge(
        self,
        amount: Decimal,
        token: str,
        patient: Patient | None = None,
        **kwargs: Any
    ) -> CardTransaction:
        # Access additional context from kwargs
        # If setToken was called with a JSON object like {"zip_code": "60007", "city": "Chicago"},
        # these will be available as kwargs
        zip_code = kwargs.get("zip_code")
        city = kwargs.get("city")
        # Or if a non-dict value was passed, it will be in additional_context
        raw_context = kwargs.get("additional_context")
        # ... rest of implementation
    ```
* * *
###  Managing Payment Methods 
These methods define how Canvas lists, stores, and deletes saved cards associated with a patient.
####  List 
Returns the patient's saved cards as a list of [`PaymentMethod`](/sdk/payment-processor-effect/#paymentmethod) effects, which Canvas renders when displaying stored payment methods.
    ```python
    from canvas_sdk.effects.payment_processor import PaymentMethod
    from canvas_sdk.v1.data import Patient
    def payment_methods(self, patient: Patient | None = None) -> list[PaymentMethod]:
       return [
                PaymentMethod(
                    payment_method_id="pm_1",
                    brand="Visa",
                    expiration_year=2025,
                    expiration_month=12,
                    card_holder_name="John Doe",
                    postal_code="12345",
                    card_last_four_digits="1234",
                )
            ]
    ```
####  Add 
Stores a new card for the patient using the tokenized card data and returns an [`AddPaymentMethodResponse`](/sdk/payment-processor-effect/#addpaymentmethodresponse) effect indicating whether the card was saved.
    ```python
    from typing import Any
    from canvas_sdk.effects.payment_processor import AddPaymentMethodResponse
    from canvas_sdk.v1.data import Patient
    def add_payment_method(self, token: str, patient: Patient, **kwargs: Any) -> AddPaymentMethodResponse:
        return AddPaymentMethodResponse(success=True)
    ```
#####  Additional Context 
The `add_payment_method` method accepts `**kwargs` which can contain additional context passed from the add card form. This is useful when you need to pass extra information from the tokenization response to the `add_payment_method` handler.
The additional context is passed via the second argument of `setToken` in your form's JavaScript (see Form Workflow). Canvas processes the `additional_context` as follows:
Input Type| Example| Passed to `add_payment_method` as  
---|---|---  
JSON object string| `'{"key": "value"}'`| `key="value"` (unpacked as kwargs)  
`None`| `null`| `additional_context=None`  
Plain string| `"some text"`| `additional_context="some text"`  
JSON number string| `"123"`| `additional_context=123`  
JSON boolean string| `"true"`| `additional_context=True`  
Example using additional context:
    ```python
    from typing import Any
    from canvas_sdk.effects.payment_processor import AddPaymentMethodResponse
    from canvas_sdk.v1.data import Patient
    def add_payment_method(self, token: str, patient: Patient, **kwargs: Any) -> AddPaymentMethodResponse:
        # Access additional context from kwargs
        # If setToken was called with a JSON object like {"zip_code": "60007", "city": "Chicago"},
        # these will be available as kwargs
        zip_code = kwargs.get("zip_code")
        city = kwargs.get("city")
        # Or if a non-dict value was passed, it will be in additional_context
        raw_context = kwargs.get("additional_context")
        # ... rest of implementation
        return AddPaymentMethodResponse(success=True)
    ```
####  Remove 
Deletes the patient's saved card identified by `token` and returns a [`RemovePaymentMethodResponse`](/sdk/payment-processor-effect/#removepaymentmethodresponse) effect indicating whether the card was removed.
    ```python
    from canvas_sdk.effects.payment_processor import RemovePaymentMethodResponse
    from canvas_sdk.v1.data import Patient
    def remove_payment_method(self, token: str, patient: Patient) -> RemovePaymentMethodResponse:
        return RemovePaymentMethodResponse(success=True)
    ```
* * *
##  Form Workflow 
Payment and Add Card forms are rendered as inner HTML inside Canvas. These forms must implement the following communication contract via JavaScript:
###  1\. Notify readiness 
This should be called once the form has fully loaded and is ready for user interaction. Canvas waits for this signal to show the form.
    ```js
    window.parent.setFormIsReady();
    ```
###  2\. Submit token after success 
Once the card details are validated and tokenized, this method must be called to pass the token back to Canvas. This token will then be used to charge or store the card.
    ```js
    window.parent.setToken("tok_123abc");
    ```
You can optionally pass a second argument with additional context that will be forwarded to the `charge` or `add_payment_method` methods. This is useful for passing extra data from the tokenization response:
    ```js
    // Pass additional context as a JSON-serializable object
    window.parent.setToken("tok_123abc", { zip_code: "111", city: "Chicago" });
    // Or pass the raw tokenization result
    const result = await paymentProvider.tokenize(cardDetails);
    window.parent.setToken(result.token, result);
    ```
The additional context will be available in the `charge` and `add_payment_method` method's `**kwargs`. See the Charge section for details on how different value types are handled.
###  3\. Report validation status 
Call this every time the validity of the form changes (e.g., input becomes valid or invalid). Canvas uses this to enable or disable the ability to submit the form programmatically.
    ```js
    window.parent.setFormIsValid(true); // or false
    ```
###  4\. Handle errors 
Call this to notify Canvas of any form-level errors (e.g., failed tokenization, invalid input). The message should help users understand what went wrong.
    ```js
    window.parent.setError("Invalid card details");
    ```
###  5\. Submit button 
The HTML form must include a button with `id="submit"`. This button is required, should remain hidden from the user, and will be clicked programmatically by Canvas when the form is considered valid and ready to be submitted.
    ```html
    <button type="submit" id="submit" hidden>Submit</button>
    ```
###  6\. Define teardown function 
This function will be called automatically when the form is unmounted or replaced. Use it to remove any event listeners or free up memory/resources.
    ```js
    window.teardown = () => {
      // Cleanup listeners, state, etc.
    };
    ```
* * *
##  Tokenization Flow 
Tokenization is the process where the sensitive card information is securely transformed into a token that can be safely used by Canvas to perform charges or save cards.
When implementing a payment processor, it's expected that your HTML forms integrate with your provider's frontend SDK to:
  - Collect and validate card input
  - Tokenize the card using the provider's secure API
  - Call `window.parent.setToken(token)` with the result
Canvas does not handle raw card input. Tokenization **must** be handled entirely by the payment provider's frontend tools within the form.
Before building a plugin, ensure:
  - Your provider offers secure frontend tokenization
  - You can integrate with their JavaScript SDK
  - You can submit token data from the form via `setToken`
* * *
##  Example Plugin 
For a complete, working reference, see the [PayTheory Payment Processor](/sdk/example-paytheory_payment_processor/) example plugin. It implements a custom `CardPaymentProcessor` that replaces the standard Stripe integration with [Pay Theory](https://paytheory.com), covering tokenization forms, charging, and saved payment method management.

# SimpleAPI Commands

Source: https://docs.canvasmedical.com/sdk/handlers-simple-api-commands/

**Any time you want to write a[command](/sdk/commands/) to a patient's chart over HTTP, this is already built for you.** `CommandAPI` is a [SimpleAPI](/sdk/handlers-simple-api-http/) that reads a request body onto a command, validates it against that command, and emits the effects. You declare the routes and who may reach them; it does the rest.
Reach for it whenever something outside Canvas needs to write to a chart — a patient-facing intake form, a device reporting readings, an internal tool your staff already work in, or a service that turns its own records into chart entries. Written by hand, each of those means parsing a body, mapping it onto a command, deciding how to report every way it can be wrong, and keeping your own record of which command you wrote. None of that is yours to write anymore.
For a walkthrough — including how to check that the caller may write to a particular note — see [Writing Commands Over HTTP](/guides/writing-commands-over-http/).
##  Quickstart 
    ```python
    from canvas_sdk.commands import HistoryOfPresentIllnessCommand
    from canvas_sdk.commands.api import CommandAPI
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, api
    class HistoryOfPresentIllnessAPI(StaffSessionAuthMixin, CommandAPI):
        PREFIX = "/v1"
        @api.post("/hpi")
        def insert(self) -> list[Response | Effect]:
            return self.originate(HistoryOfPresentIllnessCommand)
    ```
That class is five lines, and both of its base classes are load-bearing.
###  What it inherits from SimpleAPI 
`CommandAPI` is a full [SimpleAPI](/sdk/handlers-simple-api-http/). The Quickstart shows one shape — a single `POST` under a `PREFIX` — but that is just this example. Anything you can build with a SimpleAPI you can build here:
  - **As many routes as you like** , declared with `@api.get`, `@api.post`, `@api.put`, `@api.patch` and `@api.delete`. `PREFIX` is optional and prefixes them all.
  - **Path parameters.** A segment written `<name>` in a route path is a placeholder — `@api.put("/hpi/<command_id>")` matches a request to `/hpi/2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10`, and what it matched is available as `self.request.path_params["command_id"]`. That is how the routes below say _which_ command to edit or act on: the id comes from the URL rather than the body. A value is always a string, is never empty, and covers one path segment only — it cannot contain a `/`.
  - **The whole request.** `self.request` carries the method, path, headers, query parameters, the raw body, parsed JSON, text, and `multipart/form-data` parts including file uploads.
  - **Any response you want to send.** A handler always returns the ordinary SimpleAPI list of responses and effects. `originate`, `edit` and `action` each return that list already built — which is why the handlers here read `return self.originate(...)` with no brackets of their own. When you want your own response, you build the list yourself, as the `act` route does below with `[JSONResponse(...)]`, or splice onto theirs: `return [*self.originate(...), my_effect]`.
  - **Authentication.** You decide which method to use — see [Authentication](/sdk/handlers-simple-api-http/#authentication) for the schemes available.
One difference worth knowing: `CommandAPI` extends `SimpleAPI`, not [`SimpleAPIRoute`](/sdk/handlers-simple-api-http/#simpleapiroute). A class declares `PREFIX` and decorated route handlers rather than a single `PATH` with `get` and `post` methods.
What `CommandAPI` adds on top is the three methods below — `originate`, `edit` and `action` — and nothing else. Those three names are reserved: a route handler may not reuse one, and SimpleAPI raises at class-definition time if you try.
###  Where authentication comes from 
`CommandAPI` does not **choose** your authentication — which callers may write commands is your plugin's decision, not the base's. The schemes themselves are provided: declare one by listing it _before_ `CommandAPI` in the bases, from `StaffSessionAuthMixin`, `PatientSessionAuthMixin`, `APIKeyAuthMixin` and `BasicAuthMixin`. See [Authentication mixins](/sdk/handlers-simple-api-http/#authentication-mixins) for what each one needs, or write `authenticate` yourself.
Nothing is left open in the meantime. SimpleAPI's own `authenticate` returns `False`, so an endpoint that declares no scheme refuses every request rather than admitting anyone.
**That default is also why the order of the base classes matters, and why getting it wrong fails quietly** — whichever class Python reaches first decides:
Base classes| Result  
---|---  
`(StaffSessionAuthMixin, CommandAPI)`| The mixin answers first. Authentication works as you expect.  
`(CommandAPI, StaffSessionAuthMixin)`| SimpleAPI answers first, and it refuses everything. **Every request is rejected** , with no error to tell you why.  
> **Warning:** An authentication mixin establishes _who_ the caller is, not _what_ they may write. `StaffSessionAuthMixin` only checks that the session belongs to a staff member — it does not consider roles, and it says nothing about whether that person may write to the note in the request body. For that check, see [Writing Commands Over HTTP](/guides/writing-commands-over-http/).
##  A complete endpoint 
The Quickstart creates a command. Most endpoints also need to change one afterwards, which means three routes — create, update, and apply an action such as committing it. All three live on one class, and each is a single call:
    ```python
    from http import HTTPStatus
    from canvas_sdk.commands import HistoryOfPresentIllnessCommand
    from canvas_sdk.commands.api import CommandAPI
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, api
    # The actions this endpoint will pass on. Checked against the request so a caller
    # cannot name an arbitrary attribute of the command class.
    ALLOWED_ACTIONS = {"commit", "delete", "enter_in_error"}
    class HistoryOfPresentIllnessAPI(StaffSessionAuthMixin, CommandAPI):
        PREFIX = "/v1"
        @api.post("/hpi")
        def create(self) -> list[Response | Effect]:
            return self.originate(HistoryOfPresentIllnessCommand)
        @api.put("/hpi/<command_id>")
        def update(self) -> list[Response | Effect]:
            return self.edit(HistoryOfPresentIllnessCommand, self.request.path_params["command_id"])
        @api.post("/hpi/<command_id>/<action>")
        def act(self) -> list[Response | Effect]:
            action = self.request.path_params["action"]
            if action not in ALLOWED_ACTIONS:
                return [
                    JSONResponse(
                        {"error": "unsupported action", "allowed": sorted(ALLOWED_ACTIONS)},
                        status_code=HTTPStatus.BAD_REQUEST,
                    )
                ]
            return self.action(
                HistoryOfPresentIllnessCommand,
                self.request.path_params["command_id"],
                action,
            )
    ```
Staging a note entry, committing it, and retracting it, against that endpoint:
    ```shell
    # Create it, staged for a human to finish.
    curl -X POST https://example.canvasmedical.com/plugin-io/api/my_plugin/v1/hpi \
      -H 'Content-Type: application/json' \
      -d '{
            "note_id": "d2194110-5c9a-4842-8733-ef09ea5ead11",
            "values": {"narrative": "Patient reports a cough for three days."}
          }'
    # 201 {"command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "committed": false}
    # Revise it.
    curl -X PUT https://example.canvasmedical.com/plugin-io/api/my_plugin/v1/hpi/2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10 \
      -H 'Content-Type: application/json' \
      -d '{"values": {"narrative": "Patient reports a dry cough for three days."}}'
    # 200 {"command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "mode": "edit"}
    # Commit it.
    curl -X POST https://example.canvasmedical.com/plugin-io/api/my_plugin/v1/hpi/2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10/commit
    # 200 {"command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "mode": "commit"}
    # Retract it. A committed command cannot be edited, so entering it in error is
    # how you take it back - then originate its replacement.
    curl -X POST https://example.canvasmedical.com/plugin-io/api/my_plugin/v1/hpi/2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10/enter_in_error
    # 200 {"command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "mode": "enter_in_error"}
    ```
The order matters: `enter_in_error` needs a **committed** command, so it only works after the commit above. Sent against the staged command it would have been refused — see State.
To serve every command from one endpoint instead of one class per command, see [Serving every command from one endpoint](/guides/writing-commands-over-http/#serving-every-command-from-one-endpoint) in the guide — the command is an argument, so a dict of them and a path parameter is all it takes.
##  Methods 
Each returns the effects and the response for you to return from the route handler. You return the list as-is; nothing else is required of the handler.
###  originate 
`originate(model)` creates a command from the request body.
Body field| Type| Required| Description  
---|---|---|---  
`note_id`|  _string_| `true`| The id of the [Note](/sdk/data-note/#note) to write the command into.  
`values`|  _object_| `false`| The command's own fields, named as the command declares them. See [Commands](/sdk/commands/) for the fields each command takes.  
`command_id`|  _string_| `false`| An id of your choosing for the new command, instead of the one the response returns.  
`commit`|  _boolean_| `false`| Commit the command as well as creating it. Defaults to `false`, leaving it staged for a human to finish.  
`metadata`|  _object_| `false`| A flat `{"key": "value"}` map attached to the command. See [Command metadata](/sdk/effect-command-metadata/).  
Responds `201` with the id of the command it wrote and whether it was committed:
    ```json
    { "command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "committed": false }
    ```
A body using every field:
    ```json
    {
      "note_id": "d2194110-5c9a-4842-8733-ef09ea5ead11",
      "command_id": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10",
      "commit": true,
      "values": { "narrative": "Patient reports a dry cough for three days." },
      "metadata": { "source": "intake-form", "submission": "8871" }
    }
    ```
If anything is wrong with the request, nothing is written and you get a `400` instead. A value that the command refuses is reported against the field it came from:
    ```json
    {
      "error": "Validation failed",
      "validation_errors": [
        { "field": "values.narrative", "message": "String should have at most 512 characters" }
      ]
    }
    ```
A problem with the envelope rather than the values reads the same way, without the `values.` prefix — here a body that left `note_id` out:
    ```json
    {
      "error": "Validation failed",
      "validation_errors": [
        { "field": "note_id", "message": "Field required" }
      ]
    }
    ```
Every field at fault is reported at once, so a caller sees the whole list rather than fixing one problem per round trip. The other statuses this route can answer with are in Responses.
###  edit 
`edit(model, command_id)` updates a **staged** command. The command is addressed by id in your route, and the body carries `values` and `metadata`:
    ```json
    { "values": { "narrative": "Patient reports a dry cough for three days." } }
    ```
> **Warning:** `values` replaces the command's fields as a whole and is re-validated in full — it is not a patch. A field you leave out is not left alone; send the complete set of values you want the command to end up with.
Responds `200`:
    ```json
    { "command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "mode": "edit" }
    ```
Three things can go wrong, and each is checked before anything is written.
**The id matches no command of this type** — a `404`:
    ```json
    { "error": "No hpi command with that id" }
    ```
**The command is not staged** — a `400` naming the state it is in and the one the operation needed. A committed command cannot be edited; enter it in error and originate its replacement instead:
    ```json
    {
      "error": "a committed command cannot be edited",
      "state": "committed",
      "required_state": "staged",
      "validation_errors": []
    }
    ```
**A value is wrong for its field** — a `400` in the same shape `originate` returns, reported against `values.<field>`. A body that is not a JSON object at all is a `400` too, carrying `"Request body must be a JSON object"`.
See State for which operations each state allows, and Responses for the full list of statuses.
###  action 
`action(model, command_id, action)` runs one of the command's own methods. It takes no request body, and responds `200` naming what it did:
    ```json
    { "command_uuid": "2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10", "mode": "commit" }
    ```
`action` names a method on the command class, and each one builds the corresponding [command effect](/sdk/effects/#commands):
Action| What it does| Required state  
---|---|---  
`commit`| Signs the staged command into the note.| staged  
`delete`| Removes the staged command from the note.| staged  
`enter_in_error`| Marks a committed command as entered in error.| committed  
`review`| Places the command into review status.| set by the command — see State  
`send`| Transmits the command to an external system.| set by the command — see State  
`delegate`| Delegates the order to someone else to complete.| set by the command — see State  
`sign`| Signs the order.| set by the command — see State  
**No command supports all of them, and not even`commit` is universal.** Which actions a command accepts is listed per command in [Commands](/sdk/effects/#commands) — check there before wiring a route, because an action the command does not support is a `400`. The ones worth knowing up front:
  - `review` and `send` belong to [Prescribe](/sdk/commands/#prescribe), [Refill](/sdk/commands/#refill) and [Adjust Prescription](/sdk/commands/#adjustprescription), and `send` also to [Lab Order](/sdk/commands/#laborder). Those four are **not** committed — sending is how they are finished.
  - `delegate` and `sign` belong to [Imaging Order](/sdk/commands/#imagingorder) and [Refer](/sdk/commands/#refer), which are not committed either.
  - [Reason for Visit](/sdk/commands/#reasonforvisit) supports `originate`, `edit` and `delete` only.
  - [Chart Section Review](/sdk/commands/#chartsectionreview) is committed as it is originated, so it takes `originate` and nothing else.
  - [Custom commands](/sdk/commands-custom-command/) render read-only content, so they are neither edited nor committed.
An action the command class does not have is a `400`:
    ```json
    { "error": "HistoryOfPresentIllnessCommand does not support the 'review' action", "validation_errors": [] }
    ```
> **Danger:** The action usually arrives from the request, and it is passed to `getattr` on the command. Check it against a set you control first — as `ALLOWED_ACTIONS` does above — or a caller can name any attribute of the command class.
##  Field values 
`values` carries the command's own fields, named exactly as the command declares them. Each command's fields are listed under [Commands](/sdk/commands/) — `values` accepts the same set, so that page is the reference for what may go in here.
Commands parse leniently, so JSON's own types are enough. Posting to an [Allergy](/sdk/commands/#allergy) endpoint:
    ```json
    {
      "note_id": "d2194110-5c9a-4842-8733-ef09ea5ead11",
      "values": {
        "narrative": "Hives within an hour of eating shellfish.",
        "severity": "mild",
        "approximate_date": "2026-08-04"
      }
    }
    ```
  - `narrative` is a plain string, capped at 512 characters by the command.
  - `severity` is an enum, given as its value — `"mild"`, not `AllergyCommand.Severity.MILD`.
  - `approximate_date` is a date, given as an ISO string.
  - A number may arrive as a number or as a string: `12` and `"12"` are both read as `12`.
A key that is not a field on the command is **refused** , not dropped — silently ignoring a typo would write a blank command over it. Every unknown key is reported at once, against `values.<field>`:
    ```json
    {
      "error": "Validation failed",
      "validation_errors": [
        { "field": "values.narative", "message": "Unexpected field" }
      ]
    }
    ```
`note_id`, `command_id`, `commit` and `metadata` are the envelope, not fields — they sit alongside `values`, not inside it, and they are kept out of what the command writes.
###  Structured fields 
Not every field is a scalar. A number of commands take a structured value — an object, or a list of them — and each arrives as ordinary nested JSON. You do not construct the SDK type; you send its shape:
Type| Example value  
---|---  
[`Allergen`](/sdk/commands/#allergy-allergen)| `{"concept_id": 91, "concept_type": 2}`  
[`Coding`](/sdk/commands/#coding)| `{"system": "http://snomed.info/sct", "code": "44054006", "display": "Diabetes mellitus type 2"}`  
[`ClinicalQuantity`](/sdk/commands/#clinicalquantity)| `{"representative_ndc": "0093-1023", "ncpdp_quantity_qualifier_code": "C48542"}`  
[`ServiceProvider`](/sdk/commands/#serviceprovider)| `{"first_name": "Ada", "last_name": "Lovelace", "specialty": "Cardiology", "practice_name": "Mercy"}`  
[`TaskAssigner`](/sdk/commands/#taskassigner)| `{"to": "staff", "id": 5}`  
[`TestValue`](/sdk/commands/#poclabtest-testvalue)| `[{"label": "Glucose", "value": "98"}]`  
[`CompoundMedicationData`](/sdk/commands/#prescribe-compoundmedicationdata)| `{"formulation": "cream", "potency_unit_code": "C28253", "controlled_substance": "0"}`  
[`Answer` and `Selection`](/sdk/commands/#questionnaire-answer)| `[{"question_id": 15, "response": [{"option_id": 201, "comment": "left side"}]}]`  
Each type's own fields are documented with the command that uses it — follow the link for what is required and what each field means.
> **Warning:** An enum nested inside one of these is given by its **value** , not its name. `Allergen.concept_type` takes `2`, not `"MEDICATION"`; `TaskAssigner.to` takes `"staff"`, not `"STAFF"`. A name is refused with an `enum` validation error naming the values it will accept.
Answering a questionnaire is the largest of these, and the whole [`answers`](/sdk/commands/#questionnaire) list goes in `values` like any other field:
    ```json
    {
      "note_id": "d2194110-5c9a-4842-8733-ef09ea5ead11",
      "values": {
        "questionnaire_id": "c1a2b3d4-e5f6-4a7b-8c9d-0e1f2a3b4c5d",
        "answers": [
          { "question_id": 12, "response": "Three times a week." },
          { "question_id": 13, "response": 42 },
          { "question_id": 14, "response": 101 },
          { "question_id": 15, "response": [{ "option_id": 201 }, { "option_id": 202, "comment": "left side" }] }
        ]
      }
    }
    ```
The same route serves [Review of Systems](/sdk/commands/#review-of-systems), [Structured Assessment](/sdk/commands/#structuredassessment) and [Physical Exam](/sdk/commands/#physicalexam), which take `answers` too.
##  Metadata 
`metadata` attaches a flat `{"key": "value"}` map to the command. It is stored as sent and nothing in Canvas interprets it, which makes it the place to record what the entry meant on your side:
    ```json
    {
      "note_id": "d2194110-5c9a-4842-8733-ef09ea5ead11",
      "values": { "narrative": "Patient reports a dry cough for three days." },
      "metadata": { "source": "intake-form", "submission": "8871", "version": "2" }
    }
    ```
Both `originate` and `edit` accept it. Values must be strings — send `"8871"`, not `8871`.
Each pair becomes an `upsert_metadata` effect applied after the effect that writes the command, so a key sent twice ends up holding the last value. See the [Command Metadata effect](/sdk/effect-command-metadata/) for how the same storage is written from a plugin, the [Command Metadata Create form effect](/sdk/command-metadata-create-form-effect/) for collecting it from a user in the chart, and [CommandMetadata](/sdk/data-command/#commandmetadata) for reading it back.
##  Responses 
Status| When  
---|---  
`201`| The command was created.  
`200`| An edit or an action was applied.  
`400`| The body is not a JSON object, a value is wrong for its field, or the command's state does not allow the operation.  
`404`| No command **of this type** has that id. The lookup is scoped by command type, so an id belonging to a different command is a miss rather than a cross-type edit.  
`409`| The `command_id` you chose already belongs to a command.  
**Every rejection has the same shape** — an `error` summarising it and a `validation_errors` list, empty when nothing field-specific was at fault. A caller can render all of them the same way.
A value that is wrong for its field:
    ```json
    {
      "error": "Validation failed",
      "validation_errors": [
        { "field": "values.narrative", "message": "Input should be a valid string" }
      ]
    }
    ```
A body that is not a JSON object at all:
    ```json
    { "error": "Request body must be a JSON object", "validation_errors": [] }
    ```
An id matching no command of this endpoint's type:
    ```json
    { "error": "No hpi command with that id" }
    ```
That `404` covers three cases at once, deliberately: no command has the id, a command has it but is of a different type, or the id is not a well-formed UUID. The lookup is scoped to the command type this endpoint serves, so an id belonging to a Plan command reaching a History of Present Illness endpoint is a miss rather than a cross-type edit.
###  Choosing the command's id 
Passing `command_id` is worth doing when the thing you are writing already has an identity on your side: you can then ask whether it reached the chart by that id rather than storing a mapping.
**It has to be a real UUID.** It is not a free-text key of your own, so generate one rather than composing it:
    ```shell
    uuidgen                        # 2588AA22-9D0E-4F1F-9B28-6F0E6A1C9A10
    python -c 'import uuid; print(uuid.uuid4())'
    node  -e 'console.log(crypto.randomUUID())'
    ```
Anything that will not parse as a UUID is a `400` before the command is looked at — `"order-8871"` gives `Input should be a valid UUID, invalid character: found 'o' at 1`, and `"8871"` gives `Input should be a valid UUID, invalid length`. The 32-character form without dashes is accepted, so either `2588aa22-9d0e-4f1f-9b28-6f0e6a1c9a10` or `2588aa229d0e4f1f9b286f0e6a1c9a10` will do.
If your own identifier is not a UUID, derive one from it deterministically — `uuid.uuid5()` over a namespace and your key — so the same record always produces the same command id.
Posting the same id twice answers `409` rather than writing a second command, which makes a retry safe:
    ```json
    { "error": "a command already has that id", "command_uuid": "2588aa22-…", "validation_errors": [] }
    ```
###  State 
Some operations only apply to a command in a particular state. Which operations a command accepts at all is a separate question, answered per command by the [command type table](/sdk/effects/#commands).
Operation| Required state  
---|---  
`edit`| staged  
`delete`| staged  
`commit`| staged  
`enter_in_error`| committed  
`review`, `send`, `delegate`, `sign`| Whatever the command requires. `CommandAPI` sets no state for these; the command enforces its own rules as it builds the effect.  
A refusal is a `400`, naming the state the command is in and the one it needed:
    ```json
    {
      "error": "a committed command cannot be edited",
      "state": "committed",
      "required_state": "staged",
      "validation_errors": []
    }
    ```
##  Naming route handlers 
A route handler cannot be called `originate`, `edit` or `action` — those are the methods you are calling. Name handlers for the HTTP verb they serve.

# SimpleAPI HTTP

Source: https://docs.canvasmedical.com/sdk/handlers-simple-api-http/

The Canvas SDK provides a way to define an HTTP API with any number of endpoints in your instance. Developers can define the routes and implement the code that will handle incoming HTTP requests.
This feature allows developers to create endpoints that can receive webhook events from other services. An endpoint receiving a request can invoke Effects in a Canvas instance, send another request to a different service, or simply return a response back to the requester.
##  Quickstart 
Follow the instructions in [Your First Plugin (with Claude Code)](https://docs.canvasmedical.com/guides/your-first-plugin-with-claude-code/) to create a plugins project. For this exercise, use `my_api` as your project (i.e. plugin) name.
Open `CANVAS_MANIFEST.json` in your editor. You can modify filenames, directory structures, and class names as you see fit in your project, but for this exercise, we are just going to set the value at `components -> handlers -> 0 -> class` to be `my_api.handlers.my_handler:MyAPI`.
We're going to need a secret value for authentication. The instructions for declaring secrets are outlined on the [Your First Plugin (Manual)](https://docs.canvasmedical.com/guides/your-first-plugin/) page. Declare a secret in `CANVAS_MANIFEST.json` named `my-api-key`.
Open `my_api/handlers/my_handler.py` and replace the contents of the file with this code:
    ```python
    from hmac import compare_digest
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            provided_api_key = credentials.key
            api_key = self.secrets["my-api-key"]
            # compare_digest requires bytes, so we must encode the strings
            return compare_digest(provided_api_key.encode(), api_key.encode())
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
The next step is to deploy your plugin; the instructions for doing so are on the [Your First Plugin (Manual)](https://docs.canvasmedical.com/guides/your-first-plugin/) page.
You can see in the code above that the `authenticate` method is going to authenticate using API key authentication. We've already declared the secret, so now we need to generate a value and set it on your instance. You can generate an API key like this:
    ```shell
    python -c "import secrets; print(secrets.token_hex(16))"
    ```
Copy the value that it prints out and set the value for `my-api-key` in your plugin secrets on your instance.
Now that your plugin is deployed and your secret is set, you can send requests to your endpoint with `curl`. The `curl` command would look like the following (note that you will need to supply your instance name and API key):
    ```shell
    curl --location 'https://<instance-name>.canvasmedical.com/plugin-io/api/my_api/routes/hello-world' \
         --header 'Authorization: <api-key>'
    ```
##  Defining APIs 
The Canvas SDK offers two styles for defining API endpoints. To implement an API endpoint or set of endpoints using one of the two styles, your handler will simply inherit from a specific base class. The following HTTP verbs are supported:
  - GET
  - POST
  - PUT
  - DELETE
  - PATCH
###  SimpleAPIRoute 
For handlers that inherit from **SimpleAPIRoute** , you set a class variable in your handler called `PATH` as in the example above, and then implementations of the HTTP verbs you wish to support on that path. The method names will match the names of the HTTP verbs, but lowercased.
The plugin name and the `PATH` value together will form the unique part of the full URL for your endpoint. The format of the full URL will be:
`https://<instance-name>.canvasmedical.com/plugin-io/api/<plugin-name>/<PATH>`
We can adapt the previous example to add a POST endpoint for the same route on the same handler:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            ...
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world from my GET endpoint!"})
            ]
        def post(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world from my POST endpoint!"})
            ]
    ```
The handler can now respond to both GET and POST requests at `/routes/hello-world`.
###  SimpleAPI 
For handlers that inherit from **SimpleAPI** , the syntax is a little different. You can include any number of endpoints in your handler class, and you can name your route handling methods anything you wish. Here is an example:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPI, api
    class MyAPI(SimpleAPI):
        PREFIX = "/routes"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            ...
        @api.get("/hello-world")
        def hello_world_get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world from my GET endpoint!"})
            ]
        @api.post("/hello-world")
        def hello_world_post(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world from my POST endpoint!"})
            ]
        @api.get("/goodbye")
        def goodbye_get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Goodbye from my GET endpoint!"})
            ]
    ```
This syntax will be familiar if you have used Python API frameworks like `Flask` or `FastAPI`. The decorator functions are named for the HTTP verb you wish to implement on the route, and the URL path is passed into the decorator function. If you have many endpoints that you wish to share the same authentication, this syntax may be more convenient.
You can also specify a path `PREFIX` value for endpoint grouping purposes, as shown in the example above. If you have multiple endpoints that will all have the same path prefix, you can specify it by setting a value for `PREFIX`. With `PREFIX` set, each endpoint does not have to individually specify the `/routes` portion of the URL path.
###  Path patterns 
If you want to set up an endpoint that will respond to requests where the path matches a pattern rather than an exact string, you can use a path pattern. This is common in cases where the path of an endpoint contains a resource identifier.
You can specify a path pattern by by denoting any number of the path parameters in the path using `<>` syntax, with the name of the path parameters in between the angle brackets. Path parameter names must be be unique within the path. They can also be specified in the path prefix (for **SimpleAPI** handlers).
Path parameters will be extracted from the path and will be available on the request object in the `path_params` attribute.
In the example below, the value `id` is specified as part of the path, and can be accessed by the handler:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world/<id>"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            ...
        def get(self) -> list[Response | Effect]:
            id_ = self.request.path_params["id"]
            return [
                JSONResponse(
                    {
                        "message": "Hello world from my GET endpoint!",
                        "id": id_
                    }
                )
            ]
    ```
####  Path matching 
When you specify routes using path patterns, it is possible that multiple endpoints may match with a request. This has a few implications that need to be considered, because only one endpoint can provide a response.
If the endpoints that match are all part of the same handler class, then the request will be handled by the endpoint that appears highest up in the class definition, i.e. the one that is defined first. Consider two endpoints specified to match the following patterns:
    /routes/hello-world/current-user
    /routes/hello-world/<id>
The first uses an exact match, and the second uses a pattern. The path `/routes/hello-world/current-user` matches both of those patterns. However, if you register the second endpoint first it would never be possible for a request with the path of `/routes/hello-world/current-user` to match with the endpoint for `/routes/hello-world/current-user`. If you need to define endpoints that use exact matching that may overlap with endpoints defined with path patterns, order must be carefully considered.
If, however, you have defined multiple **SimpleAPIRoute** or **SimpleAPI** handlers, and a request matches with multiple endpoints across these handlers, an error condition will result. There is not a way to specify priority across handlers, so if you need fine-grained control over request routing for endpoints that use path patterns, make sure they are contained within the same handler class.
###  Request objects 
When a handler is invoked to handle an incoming HTTP request, the request object is available as an attribute on the handler. The request method, path, query parameters, content type, and body are all available as attributes on the request object:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    from logger import log
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            ...
        def get(self) -> list[Response | Effect]:
            request = self.request
            # HTTP method
            method = request.method
            # URL path component
            path = request.path
            # Raw query string
            query_string = request.query_string
            # Query parameters as a key-value mapping
            query_params = request.query_params
            # Request headers
            headers = request.headers
            # Request body content type
            content_type = request.content_type
            # Raw body
            body = request.body
            # JSON body as a Python dictionary (for requests with application/json content types)
            json_body = request.json()
            # Body as plain text
            text_body = request.text()
            # Body parsed as form data
            form_data = request.form_data()
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
####  Key-value mappings 
Attributes on the request object like headers, query parameters, and form data can in most cases be represented by mappings containing key-value pairs (e.g. Python dictionaries) with a small caveat: keys are not required to be unique. Because of this, there can be more than one value per key.
These attributes are represented by a data structure that most of the time will behave like a Python dictionary, unless you want to access the additional values for a key. If you do request the value for a key using standard dictionary syntax, you will get the first value that was encountered for that key. If you want the other values, you will need to use different methods to access them.
Here is an example showing how to access the additional values:
    ```python
    # Request sent to /route?value1=a&value1=b&value2=c
    query_params = request.query_params
    # Get the first value for value1
    value1: str = query_params["value1"]
    # Get all values for value1 with get_list
    value1_all: list[str] = query_params.get_list("value1")
    # Iterate over all query parameters (repeating keys if necessary) with multi_items
    for key, value in query_params.multi_items():
        log.info(f"key:   {key}")
        log.info(f"value: {value}")
    ```
####  Forms 
If your endpoint is set up to accept `application/x-www-form-urlencoded` or `multipart/form-data` data, there is method named `form_data` on the request object that will parse the request body. This method will return a key-value mapping containing `FormPart` objects, each of which represents a subpart of the form.
Every subpart in a form has a name, and these names are the keys in the mapping that is returned by the method. A `FormPart` can represent either a simple string value or a file. A `FormPart` that represents a string will have attributes for `name` and `value`. A `FormPart` that represents a file will have attributes for `name`, `filename`, `content`, `content_type`.
If the content type of a request is `application/x-www-form-urlencoded`, then all `FormPart` objects will represent simple string values. If the content type of a request is `multipart/form-data`, then each `FormPart` object may represent either a simple string value or a file.
Here is an example of how to use the `form_data` method to iterate over the subparts of a request body with form data:
    ```python
    form_data = request.form_data()
    # To iterate over all parts, we have to use the multi_items method because there may be more than
    # one part with the same name
    for name, part in form_data.multi_items():
        log.info(f"part name:    {name}")
        if part.is_file():
            # It's a file
            log.info(f"content:      {part.content}")
            log.info(f"filename:     {part.filename}")
            log.info(f"content type: {part.content_type}")
        else:
            # It's a simple string
            log.info(f"value:        {part.value}")
    ```
If you know the name of the subparts you are looking for, you can also access the subparts directly by looking up the name in the mapping returned by `form_data`:
    ```python
    form_data = request.form_data()
    # Get the first part named "my-part-name"
    part = form_data["my-part-name"]
    # Get all parts named "my-part-name"
    parts_all = form_data.get_list("my-part-name")
    ```
###  Responses 
Endpoint handlers may return zero or one response objects and any number of Effects. Handlers that return multiple response objects will return a **500 Internal Server Error** response back to the requester. If your endpoint does not provide a response object, then the requester will receive a **204 No Content** response.
####  Response types 
Several response types are provided for convenience:
  - HTMLResponse
  - JSONResponse
  - PlainTextResponse
  - Response (for returning raw content)
In addition to the response body, you can also specify the response status code and the response headers.
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import HTMLResponse, JSONResponse, PlainTextResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            ...
        def get(self) -> list[Response | Effect]:
            return [
                HTMLResponse(
                    "<p>Hello world from my GET endpoint!</p>",
                    status_code=HTTPStatus.OK,
                    headers={"My-Header", "my header value"}
                )
            ]
        def post(self) -> list[Response | Effect]:
            return [
                JSONResponse(
                    {"message": "Hello world from my POST endpoint!"},
                    status_code=HTTPStatus.CREATED,
                    headers={"My-Header", "my header value"}
                )
            ]
        def put(self) -> list[Response | Effect]:
            return [
                PlainTextResponse(
                    "Hello world from my PUT endpoint!",
                    status_code=HTTPStatus.ACCEPTED,
                    headers={"My-Header", "my header value"}
                )
            ]
        def patch(self) -> list[Response | Effect]:
            return [
                Response(
                    b'{"message": "Hello world from my PATCH endpoint!"}',
                    status_code=HTTPStatus.NOT_MODIFIED,
                    headers={"My-Header", "my header value"},
                    content_type="application/json"
                )
            ]
    ```
####  Returning Effects 
**SimpleAPI** endpoints can return any number of Effects just like any Canvas plugin; this is why **SimpleAPI** endpoints return a list of items rather than just a single response object.
Any effects present in the list returned by an endpoint will be processed by your Canvas instance, and the response object, if provided, will be sent back to the original requester.
###  Asynchronous requests 
By default, **SimpleAPI** requests are processed synchronously—the caller waits for the plugin to finish executing before receiving a response. If you prefer an immediate acknowledgement instead, include the `Prefer: respond-async` header in your request:
    ```bash
    curl --location 'https://<instance-name>.canvasmedical.com/plugin-io/api/<plugin-name>/<route>' \
         --header 'Authorization: <api-key>' \
         --header 'Prefer: respond-async'
    ```
When this header is present, Canvas will return a **202 Accepted** response right away and continue executing the plugin in the background. Any effects returned by the handler will still be processed by your Canvas instance; however, no response body from the handler will be delivered to the caller.
Note that authentication failures and plugin-not-found errors are always returned synchronously, regardless of this header.
###  Authentication 
Defining an `authenticate` method on your handler is required. By default, **SimpleAPI** handlers will return a **401 Unauthorized** response if no `authenticate` method is defined. The `authenticate` method should return `True` or `False` depending on whether the requester is authenticated.
Please keep in mind that while setting plugins secrets on your instance is out of scope for this guide, best practices would dictate that most `authenticate` methods would use these secrets to authenticate credentials in a request (OAuth being a notable exception). Your secrets can be accessed through the `secrets` attribute on the handler.
Additionally, to assist with adhering to security and cryptography best practices, the Python `hashlib`, `hmac`, and `secrets` modules are available for use.
Examples of how to define `authenticate` methods for various authentication schemes are shown in the next section, but if you are interested in something that is more "batteries included", please skip ahead to the Authentication mixins section below. The API key authentication mixin is a good choice that offers simplicity and good security if you need something to get started.
####  Authentication schemes 
The Canvas SDK can parse and validate the format of the Authentication header automatically for several authentication schemes, but you must authenticate the credentials in your `authenticate` method. You can specify which authentication scheme you want to use for your route or API in the method signature of your `authenticate` method.
#####  Basic 
For Basic authentication, use `BasicCredentials`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import BasicCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: BasicCredentials) -> bool:
            provided_username = credentials.username
            provided_password = credentials.password
            # Validate provided username and password against a username and password in self.secrets
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
#####  Bearer 
For Bearer authentication, use `BearerCredentials`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import BearerCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: BearerCredentials) -> bool:
            provided_token = credentials.token
            # Validate provided access token via OAuth
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
#####  API key 
For API key authentication, use `APIKeyCredentials`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import APIKeyCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: APIKeyCredentials) -> bool:
            provided_api_key = credentials.key
            # Validate provided key against an API key in self.secrets
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
#####  Session 
To authenticate using a logged-in user's session, use `SessionCredentials`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import SessionCredentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: SessionCredentials) -> bool:
            logged_in_user = credentials.logged_in_user
            # Structure looks like:
            # {
            #     "id": "abc123",
            #     "type": "Staff"
            # }
            # Where "type" is "Staff" or "Patient"
            # You could authenticate based on type or check to see if the
            # individual is in a particular group or team.
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
#####  Custom 
It's also possible to create custom authentication schemes. There are two ways to do this.
The first way is to access authentication headers on the request object directly. If you wish to do this, then you would define your authenticate method to take a `Credentials` object, and pull the authentication values from the request headers:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import Credentials, SimpleAPIRoute
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: Credentials) -> bool:
            provided_api_key = self.request.headers["My-API-Key"]
            provided_app_key = self.request.headers["My-App-Key"]
            # Validate provided credentials against the credentials in self.secrets
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
Another way to do this is by defining your own `Credentials` subclass which obtains the authentication values out of the request headers:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import Credentials, SimpleAPIRoute
    from canvas_sdk.handlers.simple_api.api import Request
    class MyCredentials(Credentials):
        def __init__(self, request: Request) -> None:
            self.api_key = self.request.headers['My-API-Key']
            self.app_key = self.request.headers['My-App-Key']
    class MyAPI(SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def authenticate(self, credentials: MyCredentials) -> bool:
            provided_api_key = credentials.api_key
            provided_app_key = credentials.app_key
            # Validate provided credentials against the credentials in self.secrets
            ...
        def get(self) -> list[Response | Effect]:
            ...
    ```
####  Authentication mixins 
The Canvas SDK offers several "batteries included" authentication mixins that you can use to implement your authentication method. If you choose to use these, then the only action you must take is to ensure that you set the appropriate secrets for your plugin on your instance.
Make sure you always list the mixin class to the left of the base class, which is **SimpleAPIRoute** in the examples below.
#####  Basic 
If you want an implementation of Basic authentication, you can use the `BasicAuthMixin`. You will need to declare the `simpleapi-basic-username` and `simpleapi-basic-password` secrets in your manifest file, and then set the secrets on your instance after you deploy your plugin.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import BasicAuthMixin, SimpleAPIRoute
    class MyAPI(BasicAuthMixin, SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
#####  API key 
If you want an implementation of API key authentication, you can use the `APIKeyAuthMixin`. You will need to declare the `simpleapi-api-key` secret in your manifest file, and then set the secret on your instance after you deploy your plugin.
You can generate a secure, random API key like this:
    ```shell
    python -c "import secrets; print(secrets.token_hex(16))"
    ```
Copy the output from that command, and set the `simpleapi-api-key` secret on your instance.
After you set your secret, you can use the `APIKeyAuthMixin`:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import APIKeyAuthMixin, SimpleAPIRoute
    class MyAPI(APIKeyAuthMixin, SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
#####  Staff Session 
If you want to ensure the visiting user is a logged in staff user, you can use the `StaffSessionAuthMixin`. This makes no assertions about the particular staff member, just that they are staff, and that they are logged in.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, SimpleAPIRoute
    class MyAPI(StaffSessionAuthMixin, SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
#####  Patient Session 
If you want to ensure the visiting user is a logged in patient user, you can use the `PatientSessionAuthMixin`. This makes no assertions about the particular patient, just that they are a patient, and that they are logged in.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import PatientSessionAuthMixin, SimpleAPIRoute
    class MyAPI(PatientSessionAuthMixin, SimpleAPIRoute):
        PATH = "/routes/hello-world"
        def get(self) -> list[Response | Effect]:
            return [
                JSONResponse({"message": "Hello world!"})
            ]
    ```
##  Acting as a Canvas user 
By default, a SimpleAPI request isn't tied to a specific person, so any effects it returns — such as creating, locking, or signing a note — are recorded as Canvas Bot rather than a clinician.
To have a request run **as a specific Canvas staff member** — for example, so a note is signed under the treating provider's name — call the endpoint with an access token obtained through the [Authorization Code flow](/api/customer-authentication#authorization-code). That flow issues a token that represents the staff member who signed in and approved it. Send it as a Bearer token in the `Authorization` header, and Canvas identifies the user from the token and treats the request as coming from them, so any effects the handler returns are attributed to that staff member.
    ```bash
    curl --request POST \
      --url 'https://example.canvasmedical.com/plugin-io/api/my_plugin/note/<note-id>/sign' \
      --header 'Authorization: Bearer <access-token>'
    ```
In this example the note is signed and recorded in Canvas as signed by the staff member who authorized the access token, not by Canvas Bot.

# SimpleAPI WebSocket

Source: https://docs.canvasmedical.com/sdk/handlers-simple-api-websocket/

WebSocket APIs in Canvas let you define **channels** that clients can connect to. These APIs support one-way, server-to-client communication, and are designed for use cases such as real-time notifications.
To use websockets in a Canvas plugin, you must define the WebSocketAPI auth handler to manage access to your channel, use the `Broadcast` effect to publish messages to that channel, and create client code to manage the connection, handle new messages, and gracefully reconnect.
###  Defining a WebSocket API 
To define a WebSocket handler, subclass `WebSocketAPI`. You must implement an `authenticate` method that determines whether the connection should be accepted.
    ```python
    from canvas_sdk.handlers.simple_api.websocket import WebSocketAPI
    class MyWebSocketAPI(WebSocketAPI):
        def authenticate(self) -> bool:
            ...
    ```
If `authenticate()` returns `True`, the connection is accepted. Otherwise, it is denied.
Clients should connect using a URL that maps to your plugin and channel name:
    wss://<instance>.canvasmedical.com/plugin-io/ws/<plugin_name>/<channel_name>/
###  WebSocket Object 
When a handler is invoked, the `websocket` object is available as an attribute on the handler. This object provides details about the connection, including:
  - `channel`: The channel name from the connection URL
  - `headers`: A dictionary of headers associated with the connection
  - `api_key`: The api key, if present
  - `logged_in_user`: A dictionary like `{ "id": ..., "type": ... }` if a logged-in user is present
You can access this object within your handler methods using `self.websocket`.
> **Info:** Channel names may only contain alphanumeric, hyphen, and underscore characters.
###  Authentication 
You must implement the `authenticate()` method in your handler class. Two authentication methods are supported:
####  Session-Based (Internal Clients) 
For connections initiated from within the Canvas browser UI by a logged-in user:
    ```python
    def authenticate(self) -> bool:
        logged_in_user = self.websocket.logged_in_user
        # Structure looks like:
        # {
        #     "id": "abc123",
        #     "type": "Staff"
        # }
        # Where "type" is "Staff" or "Patient"
        # You could authenticate based on type or check to see if the
        # individual is in a particular group or team.
        ...
    ```
####  APIKey-Based (External Clients) 
For external tools or scripts, pass an auth key as a query parameter:
    wss://<instance>.canvasmedical.com/plugin-io/ws/<plugin>/<channel>?api_key=<key>
The key is made available in your handler via `self.websocket.api_key`. You can store this key as a secret.
    ```python
    def authenticate(self) -> bool:
      provided_token = self.websocket.api_key
      # Validate provided key against an API key in self.secrets
      ...
    ```
###  Broadcasting Messages 
To send a message to all connected clients on a WebSocket channel, use the `Broadcast` effect. This effect can be returned from any handler.
The `Broadcast` effect takes the following parameters:
  - `message`: A JSON-serializable Python dictionary or value.
  - `channel`: The target channel name as a string.
Here's an example using a SimpleAPI HTTP POST route to trigger a broadcast:
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Broadcast, JSONResponse, Response
    from canvas_sdk.handlers.simple_api import Credentials, SimpleAPI, api
    class WebhookAPI(SimpleAPI):
        @api.post("/callback")
        def broadcast_message(self) -> list[Response | Effect]:
            body = self.request.json()
            return [
                Broadcast(message=body, channel="notifications").apply(),
                JSONResponse({"status": "ok"}, status_code=HTTPStatus.ACCEPTED),
            ]
    ```
In this example, when the `/callback` endpoint receives a POST request, it broadcasts the request body as a message to all clients subscribed to the `notifications` channel.

# Handlers

Source: https://docs.canvasmedical.com/sdk/handlers/

The handlers module lets you define reactions to events.
Handlers respond to [Events](/sdk/events/) and return zero, one, or many [Effects](/sdk/effects/).
There are some special types of handlers, like [Protocols](/sdk/protocols/) and [CronTasks](/sdk/handlers-crontask/). These offer a differentiated interface for their particular use-cases. For example, CronTasks only ever respond to the `CRON` event, require a schedule to be specified, and expect the `execute` method to be implemented rather than `compute`.
All handlers inherit from [BaseHandler](/sdk/handlers-basehandler/), which means you always have access to event and configuration data with the following accessors:
  - `self.event`
    - Information about the event including the event type
  - `self.context`
    - Data included as the event payload
  - `self.target`
    - Identifying information to help you reference the subject of the event
  - `self.secrets`
    - Configuration key-value store for your plugin
    - Secrets have their keys defined in the `CANVAS_MANIFEST.json` and their values are set by the Canvas instance administrator after installing your plugin via the Canvas UI on your plugin's configuration page
  - `self.environment`
    - Information about the Canvas instance your plugin is being executed on.
    - Available keys:
      - `CUSTOMER_IDENTIFIER` — the instance's subdomain (e.g. `acme` for `acme.canvasmedical.com`).
      - `INSTALLATION_TIME_ZONE` — the instance's configured time zone as an IANA name (e.g. `America/Los_Angeles`). Useful for rendering times to the customer's clinicians, scheduling work in their local day, or formatting dates in user-facing output.
    - Example: `self.environment['CUSTOMER_IDENTIFIER']`

# Layout Effects

Source: https://docs.canvasmedical.com/sdk/layout-effect/

##  Patient Summary 
There are many summary sections in a patient's chart, organized by data type. While there is a default ordering, you can use an Effect to reorder them or hide some of them entirely. The `PatientChartSummaryConfiguration` class helps you craft the effect to do so.
![Before and after](/assets/images/sdk/summary-section-modified.png)
The example below shows reordering and hiding or omitting some of the sections:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.effects.patient_chart_summary_configuration import PatientChartSummaryConfiguration
    class SummarySectionLayout(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)
        def compute(self):
            layout = PatientChartSummaryConfiguration(sections=[
              PatientChartSummaryConfiguration.Section.CARE_TEAMS,
              PatientChartSummaryConfiguration.Section.SOCIAL_DETERMINANTS,
              PatientChartSummaryConfiguration.Section.ALLERGIES,
              PatientChartSummaryConfiguration.Section.CONDITIONS,
              PatientChartSummaryConfiguration.Section.MEDICATIONS,
              PatientChartSummaryConfiguration.Section.VITALS,
            ])
            return [layout.apply()]
    ```
The `PatientChartSummaryConfiguration` takes a single argument, `sections`, which is expected to be a list at least one element long, filled with choices from the `PatientChartSummaryConfiguration.Section` enum. The `.apply()` method returns a well-formed `Effect` object.
This effect is only used in response to the `PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION` event. It does nothing in any other context.
Values in the `PatientChartSummaryConfiguration.Section` enum are:
Constant| Description  
---|---  
SOCIAL_DETERMINANTS| social_determinants  
GOALS| goals  
CONDITIONS| conditions  
MEDICATIONS| medications  
ALLERGIES| allergies  
CARE_TEAMS| care_teams  
VITALS| vitals  
IMMUNIZATIONS| immunizations  
SURGICAL_HISTORY| surgical_history  
FAMILY_HISTORY| family_history  
CODING_GAPS| coding_gaps  
###  Custom Sections 
In addition to the built-in sections above, you can add fully custom sections to the chart summary. Custom sections render plugin-provided content in an iframe and are identified by a unique key. See [Patient Chart Summary Custom Section Handler](/sdk/patient-chart-summary-custom-section-handler/) for details on how to implement one.
###  Action Buttons 
Each section of the patient chart can also be customized with action buttons. Please refer to the [Action Buttons](/sdk/handlers-action-buttons/) documentation for more information.
##  Patient Profile 
The `PatientProfileConfiguration` class allows you to reorder, hide, and/or specificy whether sections load expanded or collapsed.

            ]
            effect = PatientProfileConfiguration(sections=sections).apply()
            return [effect]
    ```
The `PatientProfileConfiguration` takes a single argument, `sections`, which is expected to be a list at least one element long, filled with `PatientProfileConfiguration.Payload` objects. These are python typed dictionaries that expect a `PatientProfileConfiguration.Section` choice, which describes a section of the patient profile, and a `start_expanded` boolean, which determines if the fields in that section should be exposed by default. The `.apply()` method returns a well-formed `Effect` object.
This effect is only used in response to the `PATIENT_PROFILE__SECTION_CONFIGURATION` event. It does nothing in any other context.
Values in the `PatientProfileConfiguration.Section` enum are:
Constant| Description  
---|---  
DEMOGRAPHICS| demographics  
PREFERENCES| preferences  
PREFERRED_PHARMACIES| preferred_pharmacies  
PATIENT_CONSENTS| patient_consents  
CARE_TEAM| care_team  
PARENT_GUARDIAN| parent_guardian  
ADDRESSES| addresses  
TELECOM| telecom  
CONTACTS| contacts  
##  Panel Configuration 
This effect allows you to define which panel buttons should be displayed on the main page or the patient page.
The order of the buttons in the array will determine their order on the panel.
![Before and after](/assets/images/sdk/panel-configuration-before-after.png)(width:70%)
    ```python
    from canvas_sdk.effects.panel_configuration import PanelConfiguration
    PanelConfiguration(
      sections=[
        PanelConfiguration.PanelPatientSection.REFILL_REQUEST,
        PanelConfiguration.PanelPatientSection.LAB_REPORT,
        PanelConfiguration.PanelPatientSection.CHANGE_REQUEST,
        PanelConfiguration.PanelPatientSection.TASK,
    ], page=PanelConfiguration.Page.PATIENT).apply()
    ```
A PanelConfiguration effect consists of the following properties:
###  Attributes 
Attribute| Type| Description  
---|---|---  
`sections`| `list[PanelPatientSection] or list[PanelGlobalSection]`| list of section items.  
`page`| `Page`| PATIENT or GLOBAL.  
Values in the `PanelGlobalSection` enum are:
Constant| Description  
---|---  
APPOINTMENT| appointment  
CHANGE_REQUEST| changeRequest  
IMAGING_REPORT| imagingReport  
INPATIENT_STAY| inpatientStay  
LAB_REPORT| labReport  
MESSAGE| message  
OUTSTANDING_REFERRAL| outstandingReferral  
PRESCRIPTION_ALERT| prescriptionAlert  
RECALL_APPOINTMENT| recallAppointment  
REFERRAL_REPORT| referralReport  
REFILL_REQUEST| refillRequest  
TASK| task  
UNCATEGORIZED_DOCUMENT| uncategorizedDocument  
Values in the `PanelPatientSection` enum are:
Constant| Description  
---|---  
CHANGE_REQUEST| changeRequest  
COMMAND| command  
IMAGING_REPORT| imagingReport  
INPATIENT_STAY| inpatientStay  
LAB_REPORT| labReport  
PRESCRIPTION_ALERT| prescriptionAlert  
REFERRAL_REPORT| referralReport  
REFILL_REQUEST| refillRequest  
TASK| task  
UNCATEGORIZED_DOCUMENT| uncategorizedDocument  
##  Patient Note Header Dropdown Configuration 
The `PatientNoteHeaderDropdownConfiguration` effect allows you to define which items appear in the dropdown menu on a patient's note header (the triple dots at the top right of each note).
The order in the dropdown is preserved and grouped into specific sections, rather than being based on the plugin item order.
![Before and after](/assets/images/sdk/note-header-configuration.png)(width:60%)
    ```python
    from canvas_sdk.effects.patient_note_header_dropdown_configuration import PatientNoteHeaderDropdownConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect
    class NoteHeaderDropdownHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_NOTE_HEADER_DROPDOWN__SECTION_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [PatientNoteHeaderDropdownConfiguration(items=[
                PatientNoteHeaderDropdownConfiguration.Items.PRINT_NOTE,
                PatientNoteHeaderDropdownConfiguration.Items.PRINT_SUPERBILL,
                PatientNoteHeaderDropdownConfiguration.Items.LINK_TO_PHONE,
            ]).apply()]
    ```
###  Attributes 
Attribute| Type| Description  
---|---|---  
`items`| `list[Items]`| List of dropdown items to display.  
Values in the `PatientNoteHeaderDropdownConfiguration.Items` enum are:
Constant| Description  
---|---  
LINK_TO_PHONE| Show QR code to link mobile device to note  
SOAP| Sort note sections in SOAP order (Subjective, Objective, Assessment, Plan)  
APSO| Sort note sections in APSO order (Assessment, Plan, Subjective, Objective)  
CHANGE_LOCATION| Change the note's practice location  
CHANGE_PROVIDER| Change the note's provider  
CHANGE_DATE_OF_SERVICE| Change the note's date of service  
PRINT_SUPERBILL| Print the superbill for billing  
PRINT_ROOMING_SHEET| Print the rooming sheet for care team  
PRINT_AFTER_VISIT_SUMMARY| Print the patient after visit summary  
COPY_LINK| Copy the note's permalink to clipboard  
PRINT_NOTE| Print the note for care team  
FAX_NOTE| Fax the note to an external recipient  
FAX_EVENT_HISTORY| View fax event history for the note  
MOVE_COMMANDS| Move commands from this note to another note  
##  Provider Menu Configuration 
The `ProviderMenuConfiguration` effect allows you to define which items appear in the provider menu (the hamburger menu at the top left of Canvas).
The effect replaces the default set of items, so every item that should stay visible has to be listed. Anything you omit is not rendered. If no installed plugin emits the effect, the menu renders unchanged.
Passing an empty list is allowed and hides every native item — useful if your plugin replaces the menu entirely with its own items.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.provider_menu_configuration import ProviderMenuConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class ProviderMenuHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.GET_PROVIDER_MENU_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [ProviderMenuConfiguration(items=[
                ProviderMenuConfiguration.Items.PATIENTS,
                ProviderMenuConfiguration.Items.CAMPAIGNS,
                ProviderMenuConfiguration.Items.SETTINGS,
            ]).apply()]
    ```
Three things the effect does not do:
  - **It does not reorder the menu.** Items render in Canvas's native order and grouping, regardless of the order you list them in.
  - **It does not grant access.** Permissions still apply on top, so an item you list will still render disabled for a user who lacks the permission for it.
  - **It does not affect plugin-provided menu items.** Applications with the `provider_menu_item` scope are independent of the allow-list.
The user's avatar and name, and the **Sign out** button, are always rendered and cannot be hidden.
Because this is an allow-list rather than a block-list, it does not pick up native items added in future Canvas releases. If a new item ships and you want it visible, add it to your list — otherwise it stays hidden on your instance.
####  When the allow-list is not applied 
Canvas falls back to rendering every native item, rather than a partial or empty menu, in each of these cases:
  - No installed plugin responds to the event.
  - The plugin raises while resolving the configuration.
  - The allow-list reaches Canvas containing an item it does not recognize — the whole list is discarded, not just the unrecognized entry.
Passing something that is not an `Items` member raises a validation error when you construct `ProviderMenuConfiguration`, so most mistakes surface in your plugin before they ever reach Canvas.
If more than one installed plugin responds with a `ProviderMenuConfiguration`, the last effect Canvas receives wins — its allow-list replaces the earlier ones rather than merging with them.
###  Attributes 
Attribute| Type| Description  
---|---|---  
`items`| `list[Items]`| List of menu items to display.  
Values in the `ProviderMenuConfiguration.Items` enum are:
Constant| Description  
---|---  
SCHEDULE| Go to the schedule page  
PATIENTS| Go to the patient directory  
REVENUE| Go to the revenue page  
POPULATIONS| Go to the populations page  
CAMPAIGNS| Go to the campaigns page  
DATA_INTEGRATION| Go to the data integration queue  
QUESTIONNAIRE_BUILDER| Go to the questionnaire builder  
SETTINGS| Open the Canvas admin site in a new tab  
MULTI_FACTOR_AUTHENTICATION| Open multi-factor authentication setup in a new tab  
CHANGELOG| Open the Canvas release notes in a new tab  
HELP_CENTER| Open the Canvas help center in a new tab  
###  Hiding the Schedule item 
Hiding `SCHEDULE` does not change where providers land after logging in — that still defaults to the schedule page. Pair the effect with a [`DefaultHomepageEffect`](/sdk/default-homepage-effect/) so providers do not arrive on a page they can no longer navigate back to.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.default_homepage import DefaultHomepageEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class ScheduleFreeHomepage(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.GET_HOMEPAGE_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [DefaultHomepageEffect(page=DefaultHomepageEffect.Pages.PATIENTS).apply()]
    ```
Hiding `SCHEDULE` also leaves the Appointments filter in the side panel in place. Removing the scheduling experience end to end means coordinating three independent controls: this effect for the menu item, `PanelConfiguration` for the Appointments filter, and [`DefaultHomepageEffect`](/sdk/default-homepage-effect/) for the landing page.
Omitting `SETTINGS` or `MULTI_FACTOR_AUTHENTICATION` hides the links to the admin site and to multi-factor authentication setup, so make sure your users have another route to them if they need one.
##  Modals 
The `LaunchModalEffect` class allows you to launch modals in Canvas, providing a flexible way to display content or navigate to external resources.
###  Example Usage 
    ```python
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    class ModalEffectHandler:
        def compute(self):
            modal_effect = LaunchModalEffect(
                url="https://example.com/info",
                content=None,
                target=LaunchModalEffect.TargetType.DEFAULT_MODAL,
                title="Example Info"
            )
            return [modal_effect.apply()]
    ```
The `LaunchModalEffect` class has the following properties:
  - **url** : A string containing the URL to load within the modal. If `content` is also specified, an error will be raised.
  - **content** : A string containing the content to be displayed directly within the modal. If `url` is also provided, an error will be raised.
  - **target** : Defines where the modal should be launched. Options include:
    - `DEFAULT_MODAL`: Opens the URL in a modal centered on the screen.
    - `NEW_WINDOW`: Opens the content in a new browser window.
    - `RIGHT_CHART_PANE`: Opens the URL in the right-hand pane of the patient chart.
    - `RIGHT_CHART_PANE_LARGE`: Like above, but a bit wider.
    - `PAGE`: Opens the content as a full page.
    - `NOTE`: Opens the content within a note tab (used with Note Applications).
    - `DOCKED_PANE`: Opens the content in a persistent pane pinned to an edge of the window. This target is returned by a [Docked Application](/sdk/handlers-embedded-applications/#docked-applications), which sets `DOCK_EDGE` and `DOCK_SIZE`.
  - **title** : A string containing the title of the modal and will be displayed when minimized. Defaults to `Untitled`
###  Closing Modals from Applications 
When building applications with the Canvas SDK, you may encounter scenarios where you need to programmatically dismiss modals. This can be particularly useful in automated testing or when creating user flows that require closing modals based on certain conditions.
Here's a simple example of how to dismiss modals from your applications using JavaScript.
    ```html
    <script>
        let messagePort = null;
        // Listen for the port transfer from the Canvas Application
        window.addEventListener('message', (event) => {
          // Check if this is the INIT_CHANNEL message with a port
          if (event.data?.type === 'INIT_CHANNEL' && event.ports[0]) {
            // Store the port for later use
            messagePort = event.ports[0];
            messagePort.start();
            messagePort.postMessage({ type: 'CLOSE_MODAL' });
          }
        });
    </script>
    ```
And that's it! This script establishes a communication channel with the Canvas Application by listening for the `INIT_CHANNEL` event, capturing the message port, and then sending a `CLOSE_MODAL` message through that port to close any open modals when the application loads. You can customize the event listener to trigger the modal dismissal based on your specific requirements.
While developers might find odd to be sending a message to themselves, this is the current method supported by the Canvas SDK for dismissing modals, in order to avoid potential security issues with cross-origin messaging and flooding the main application with messages.
This twist on the _Holywood Principle_ ensures that your application remains secure while still providing the functionality needed to manage modals effectively.
##  Resizing Modals 
Modal overlays can now be dynamically resized by embedded applications using the MessageChannel API. Applications launching with a `DEFAULT_MODAL` target can send a `RESIZE` message to adjust the modal's width and/or height:
    ```html
    <script>
        let messagePort = null;
        // Listen for the port transfer from the Canvas Application
        window.addEventListener('message', (event) => {
          // Check if this is the INIT_CHANNEL message with a port
          if (event.data?.type === 'INIT_CHANNEL' && event.ports?.[0]) {
            // Store the port for later use
            messagePort = event.ports[0];
            messagePort.start();
            // Example: Resize modal to specific dimensions
            messagePort.postMessage({
              type: 'RESIZE',
              width: 800,  // pixels
              height: 600  // pixels
            });
          }
        });
    </script>
    ```
This enables embedded applications to optimize their display area based on content requirements, improving the user experience for dynamic or responsive plugin interfaces.
##  Custom HTML and Django Templates 
To facilitate the use of custom HTML, you can utilize the `render_to_string` utility from `canvas_sdk.templates` to render Django templates with a specified context. This allows for dynamic rendering of HTML that can be passed to a `LaunchModalEffect` or `PortalWidget`.
    ```python
    from typing import Any
    def render_to_string(template_name: str, context: dict[str, Any] | None = None) -> str | None:
        """Load a template and render it with the given context.
        Args:
            template_name (str): The path to the template file, relative to the plugin package.
                If the path starts with a forward slash ("/"), it will be stripped during resolution.
            context (dict[str, Any] | None): A dictionary of variables to pass to the template
                for rendering. Defaults to None, which uses an empty context.
        Returns:
            str: The rendered template as a string.
        Raises:
            FileNotFoundError: If the template file does not exist within the plugin's directory
                or if the resolved path is invalid.
        """
    ```
####  Example Template 
Consider a simple HTML file named `templates/custom_content.html`:
    ```html
    <!DOCTYPE html>
    <html>
      <head>
        <title>{{ title }}</title>
      </head>
      <body>
        <h1>{{ heading }}</h1>
        <p>{{ message }}</p>
      </body>
    </html>
    ```
This template uses Django template placeholders like `{{ title }}`, `{{ heading }}`, and `{{ message }}` to dynamically render content based on the provided context.
####  Rendering the Template in Python 
Here's how you can use the `render_to_string` utility to render the template and pass the resulting HTML to a `LaunchModalEffect` or `PortalWidget`:
    ```python
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.effects.widgets import PortalWidget
    from canvas_sdk.templates import render_to_string
    class ModalEffectHandler:
        def compute(self):
            # Define the context for the template
            context = {
                "title": "Welcome Modal",
                "heading": "Hello, User!",
                "message": "This is a dynamically rendered modal using Django templates."
            }
            # Render the HTML content using the template and context
            rendered_html = render_to_string("templates/custom_content.html", context)
            # Create a LaunchModalEffect with the rendered content
            modal_effect = LaunchModalEffect(
                content=rendered_html,
                target=LaunchModalEffect.TargetType.DEFAULT_MODAL
            )
            return [modal_effect.apply()]
    class PortalWidgetHandler:
        def compute(self):
            # Define the context for the template
            context = {
                "title": "Welcome Modal",
                "heading": "Hello, User!",
                "message": "This is a dynamically rendered modal using Django templates."
            }
            # Render the HTML content using the template and context
            rendered_html = render_to_string("templates/custom_content.html", context)
            # Create a PortalWidget with the rendered content
            portal_widget = PortalWidget(
                content=rendered_html,
                size=PortalWidget.Size.COMPACT,
                priority=25
            )
            return [portal_widget.apply()]
    ```
##  Additional Configuration 
To use URLs or custom scripts within the `LaunchModalEffect` or `PortalWidget`, additional security configurations must be specified in the `CANVAS_MANIFEST.json` file of your plugin.
  - **Allowing URLs** : URLs specified in the **url** property must be added to the `url_permissions` section of the `CANVAS_MANIFEST.json` in order for the URL to load properly.
  - **Allowing custom scripts** : If you need to load scripts from an external source, the URL for the script must be added to the `url_permissions` section of the `CANVAS_MANIFEST.json` and `'SCRIPTS'` must be in the permissions list.
  - **Requesting microphone access** : If the site in your modal or widget needs microphone access, `'MICROPHONE'` must be in the URL's permissions list.
  - **Requesting camera access** : If the site in your modal or widget needs camera access, `'CAMERA'` must be in the URL's permissions list.
  - **Requesting clipboard read access** : If the site in your modal or widget needs to read from the user's clipboard, `'CLIPBOARD_READ'` must be in the URL's permissions list.
  - **Requesting clipboard write access** : If the site in your modal or widget needs to write to the user's clipboard, `'CLIPBOARD_WRITE'` must be in the URL's permissions list.
  - **Allowing browser access to cookies from the iframe's origin** : If you want the loaded URL to access cookies for its domain, `'ALLOW_SAME_ORIGIN'` must be in the URL's permissions list. If the URL you're loading requires authentication, this will prevent your user from having to log in each time the modal is launched.
The URLs must match the format available [here](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy#host-source).
    ```json
    {
      "sdk_version": "0.1.4",
      "plugin_version": "0.0.1",
      "name": "custom_html",
      "description": "...",

        {
          "url": "https://example.com/info",
          "permissions": ["ALLOW_SAME_ORIGIN", "MICROPHONE", "CAMERA", "CLIPBOARD_READ", "CLIPBOARD_WRITE"]
        },
        {
          "url": "https://d3js.org/d3.v4.js",
          "permissions": ["SCRIPTS"]
        }

# Patient Chart Group

Source: https://docs.canvasmedical.com/sdk/patient-chart-group-effect/

##  Overview 
This effect allows developers to group items in a patient chart section. You can define multiple groups with a name, priority, and the items that belong to each group.
Currently, this is supported for the Conditions, Medications, and Detected Issues sections.
    ```python
    from canvas_sdk.effects.patient_chart_group import PatientChartGroup
    from canvas_sdk.effects.group import Group
    conditions = [{
        "id": 1,
        "codings": {
          "code": "111",
          "system": "ICD-10",
          "display": "Ophiasis",
        }
      }, {
        "id": 2,
        "codings": {
          "code": "112",
          "system": "ICD-10",
          "display": "Acute angle-closure glaucoma",
        }
    }]

# Patient Chart Summary Custom Section

Source: https://docs.canvasmedical.com/sdk/patient-chart-summary-custom-section-effect/

##  Overview 
The `PatientChartSummaryCustomSection` effect allows plugin developers to supply the content for a custom section in the patient chart summary. It is returned by a [`PatientChartSummaryCustomSectionHandler`](/sdk/patient-chart-summary-custom-section-handler/) in response to a request for the section's content.
Content can be provided as an inline HTML string or as a URL to a hosted page. An icon must always be supplied — it is shown in the chart summary header when the section is collapsed.
    ```python
    from canvas_sdk.effects.patient_chart_summary_custom_section import PatientChartSummaryCustomSection
    from canvas_sdk.templates import render_to_string
    # Serve content as an inline HTML string
    PatientChartSummaryCustomSection(
        content=render_to_string("templates/my_section.html"),
        icon="📋",
    )
    # Serve content from a hosted URL
    PatientChartSummaryCustomSection(
        url="/plugin-io/api/my_plugin/my-section",
        icon_url="/plugin-io/api/my_plugin/icon.png",
    )
    ```
##  Structure 
###  Attributes 
Attribute| Required| Type| Description  
---|---|---|---  
`content`| required (if `url` is not provided)| `str` | `None`| Inline HTML content to render in the section. Mutually exclusive with `url`.  
`url`| required (if `content` is not provided)| `str` | `None`| URL of the page to load in the section iframe. Mutually exclusive with `content`.  
`icon`| required (if `icon_url` is not provided)| `str` | `None`| Text or emoji displayed as the section icon when collapsed. Mutually exclusive with `icon_url`.  
`icon_url`| required (if `icon` is not provided)| `str` | `None`| URL of an image to use as the section icon when collapsed. Mutually exclusive with `icon`.  
###  Validation 
Exactly one of `content` / `url` must be provided, and exactly one of `icon` / `icon_url` must be provided. Providing both fields in a pair or neither will raise a `ValidationError` when `.apply()` is called.
##  Examples 
###  Inline HTML content 
Return a rendered HTML template as the section content.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_chart_summary_custom_section import PatientChartSummaryCustomSection
    from canvas_sdk.handlers.patient_chart_summary_custom_section_handler import PatientChartSummaryCustomSectionHandler
    from canvas_sdk.templates import render_to_string
    class MySectionHandler(PatientChartSummaryCustomSectionHandler):
        SECTION_KEY = "my_section"
        def handle(self) -> list[Effect]:
            return [
                PatientChartSummaryCustomSection(
                    content=render_to_string("templates/my_section.html"),
                    icon="📋",
                ).apply()
            ]
    ```
###  URL-based content 
Load the section content from a hosted endpoint. This is useful when the section is a standalone page served by a [Simple API](/sdk/handlers-simple-api/) handler.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_chart_summary_custom_section import PatientChartSummaryCustomSection
    from canvas_sdk.handlers.patient_chart_summary_custom_section_handler import PatientChartSummaryCustomSectionHandler
    class MySectionHandler(PatientChartSummaryCustomSectionHandler):
        SECTION_KEY = "my_section"
        def handle(self) -> list[Effect]:
            return [
                PatientChartSummaryCustomSection(
                    url="/plugin-io/api/my_plugin/my-section",
                    icon_url="/plugin-io/api/my_plugin/icon.png",
                ).apply()
            ]
    ```
###  Passing data to the template 
Use `render_to_string` with a context dictionary to inject dynamic data into the HTML template.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_chart_summary_custom_section import PatientChartSummaryCustomSection
    from canvas_sdk.handlers.patient_chart_summary_custom_section_handler import PatientChartSummaryCustomSectionHandler
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data.patient import Patient
    class MySectionHandler(PatientChartSummaryCustomSectionHandler):
        SECTION_KEY = "my_section"
        def handle(self) -> list[Effect]:
            patient = Patient.objects.get(id=self.target)
            return [
                PatientChartSummaryCustomSection(
                    content=render_to_string(
                        "templates/my_section.html",
                        {"patient_name": patient.first_name},
                    ),
                    icon="📋",
                ).apply()
            ]
    ```

# Patient Chart Summary Custom Section Handler

Source: https://docs.canvasmedical.com/sdk/patient-chart-summary-custom-section-handler/

The `PatientChartSummaryCustomSectionHandler` is the base class for implementing custom sections in the patient chart summary. When Canvas needs to render a custom section, it fires an event that this handler intercepts, and the handler returns a [`PatientChartSummaryCustomSection`](/sdk/patient-chart-summary-custom-section-effect/) effect with the content to display.
##  Overview 
Custom chart summary sections are registered through [`PatientChartSummaryConfiguration`](/sdk/layout-effect/#patient-summary) and served by a `PatientChartSummaryCustomSectionHandler` subclass. Each handler is responsible for exactly one section, identified by its `SECTION_KEY`.
To implement a custom section you need two things:
  1. A `PatientChartSummaryConfiguration` handler that includes the section in the layout.
  2. A `PatientChartSummaryCustomSectionHandler` subclass that returns the section content.
Both handlers must be registered in `CANVAS_MANIFEST.json`.
##  Creating a Custom Section Handler 
Subclass `PatientChartSummaryCustomSectionHandler` and:
  1. Set `SECTION_KEY` to the unique identifier of your section. This must match the key used in `PatientChartSummaryConfiguration.CustomSection`.
  2. Implement `handle()` to return a `PatientChartSummaryCustomSection` effect.
  3. The patient id is available via `self.target`. Use it to scope database queries to the current patient.
  4. The logged-in user is available via `self.actor`. Use it to tailor the section content to the specific staff member viewing the chart.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_chart_summary_custom_section import PatientChartSummaryCustomSection
    from canvas_sdk.handlers.patient_chart_summary_custom_section_handler import PatientChartSummaryCustomSectionHandler
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data.patient import Patient
    class MySectionHandler(PatientChartSummaryCustomSectionHandler):
        """Handles the PATIENT_CHART_SUMMARY__GET_CUSTOM_SECTION event for 'my_section'.
        Fetches the current patient and renders a template with their name.
        """
        SECTION_KEY = "my_section"
        def handle(self) -> list[Effect]:
            patient = Patient.objects.get(id=self.target)
            return [
                PatientChartSummaryCustomSection(
                    content=render_to_string("templates/my_section.html", { "patient_name": patient.full_name() }),
                    icon="📋",
                ).apply()
            ]
    ```
###  Required 
  - **`SECTION_KEY`** A unique string identifier for the section. Must match the key passed to `PatientChartSummaryConfiguration.CustomSection`. Omitting or leaving it empty will raise an `ImproperlyConfigured` error when the plugin loads.
  - **`handle()`** Called when Canvas requests the content for this section. Must return a list containing a single [`PatientChartSummaryCustomSection`](/sdk/patient-chart-summary-custom-section-effect/) effect.
##  Configuring Chart Summary Sections 
A custom section handler alone is not enough — the section must also be included in the chart summary layout. Use `PatientChartSummaryConfiguration` to declare which sections appear in the chart summary and in what order. For the full list of available built-in sections, see [Patient Summary layout effects](/sdk/layout-effect/#patient-summary).
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_chart_summary_configuration import PatientChartSummaryConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MySummaryConfiguration(BaseHandler):
        RESPONDS_TO = [EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)]
        def compute(self) -> list[Effect]:
            return [
                PatientChartSummaryConfiguration(
                    sections=[
                        PatientChartSummaryConfiguration.CustomSection(name="my_section"),
                        PatientChartSummaryConfiguration.Section.MEDICATIONS,
                        PatientChartSummaryConfiguration.Section.CONDITIONS,
                    ]
                ).apply()
            ]
    ```
##  Full Example 
The following example shows a complete plugin with a custom section that displays a list of items fetched from command metadata.

# Patient Portal

Source: https://docs.canvasmedical.com/sdk/patient-portal/

The Canvas SDK allows you to configure and extend the patient portal. This page is the technical reference for the portal's effects and events. For a decision-oriented overview of how much of the patient experience to build, see [Choosing Your Patient Experience](/guides/choosing-your-patient-experience/).
##  Configure Portal Menu Items 
Decide which items appear in the patient portal's menu with the `PatientPortalMenuConfiguration` effect, returned from a handler on the `PATIENT_PORTAL__MENU_CONFIGURATION` event. Unlike the account-wide page toggles managed by Canvas Support, this lets you show or hide menu items with your own logic (per patient, program, and so on).
The list you return **replaces** the built-in menu — include every built-in item you want shown, in the order you want them to appear (**the list order is the navigation order**), and omit any you want hidden.
An item only appears if its page is **also enabled in your portal settings** (the `PATIENT_APP_*` settings managed by Canvas Support — see [Managing the Patient Portal](https://canvas-medical.help.usepylon.com/articles/7348270931-managing-the-patient-portal)). This effect selects and orders among the _enabled_ pages: it can hide or reorder them, but it can't surface a page that's turned off. Patient-portal [applications](/sdk/handlers-applications/) aren't part of this list — they're appended to the navigation after the built-in items through their own registration.
Attribute| Type| Description  
---|---|---  
`items`| list[`MenuItems`]| The built-in menu items to show, in navigation order (at least one). Replaces the default set — omit an item to hide it.  
**`MenuItems`** values:
Member| Value| Menu item  
---|---|---  
`APPOINTMENTS`| `"appointments"`| Appointments  
`MESSAGING`| `"messaging"`| Messaging  
`MY_HEALTH`| `"my_health"`| My Health  
`PAYMENTS`| `"payments"`| Payments  
`LABS`| `"labs"`| Lab results  
`CONTACT`| `"contact"`| Contact  
`RECORDS`| `"records"`| Health Records  
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_portal_menu_configuration import PatientPortalMenuConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__MENU_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [
                PatientPortalMenuConfiguration(
                    items=[
                        PatientPortalMenuConfiguration.MenuItems.APPOINTMENTS,
                        PatientPortalMenuConfiguration.MenuItems.MESSAGING,
                    ]
                ).apply()
            ]
    ```
##  Portal Landing Page Widgets 
The `PortalWidget` class adds widgets to the patient portal landing page. Return `PortalWidget` effects from a handler on the `PATIENT_PORTAL__WIDGET_CONFIGURATION` event. You can fully customize a widget or use a ready-made one provided by Canvas (Appointments, Messaging).
The `PortalWidget` class has the following attributes:
Attribute| Type| Description  
---|---|---  
`url`| `str`| A URL to load within the widget.  
`content`| `str`| Content to display directly within the widget.  
`component`| `Component`| A ready-made Canvas widget: `APPOINTMENTS` (upcoming appointments) or `MESSAGING` (quick messaging).  
`size`| `Size`| Widget width on the grid: `EXPANDED` (12 columns), `MEDIUM` (8 columns), or `COMPACT` (4 columns). All are 300px tall. Defaults to `EXPANDED`.  
`priority`| `int`| Orders widgets within the portal; a lower number is higher priority. Defaults to `100`.  
**Validation:** exactly one of `url`, `content`, or `component` must be set — providing more than one, or none, raises an error.
###  Example Usage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.widgets import PortalWidget
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__WIDGET_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [
                PortalWidget(
                    url="https://example.com/info",
                    size=PortalWidget.Size.COMPACT,
                    priority=25,
                ).apply()
            ]
    ```
For a full walkthrough with examples, see the [Custom Landing Page guide](/guides/custom-landing-page/). Example plugins: [patient_portal_plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_portal_plugin), and the MSF [urgent-care-self-scheduler](https://github.com/medical-software-foundation/canvas/tree/main/extensions/urgent-care-self-scheduler) (a "Need to be seen today?" widget).
##  Customize Appointment Cards 
Customize your patient appointment cards so patients can easily join their telehealth appointments, cancel or reschedule appointments. Each appointment can be customized individually, allowing each one to have its own unique settings.
Each action is decided per appointment: Canvas fires a `PATIENT_PORTAL__APPOINTMENT_CAN_*` event for the appointment, and your handler returns the matching `PATIENT_PORTAL__APPOINTMENT_IS_*` (or `PATIENT_PORTAL__APPOINTMENT_SHOW_MEETING_LINK`) effect with a `{"result": <bool>}` payload — `False` hides the action; for the telehealth **Join** link, `True` shows it. Each action's exact event, effect, and payload are shown below.
MSF example: [portal_disable_cancel_appts](https://github.com/medical-software-foundation/canvas/tree/main/extensions/portal_disable_cancel_appts) hides the Cancel action.
###  Hide 'Cancel' button 
Respond to `PATIENT_PORTAL__APPOINTMENT_CAN_BE_CANCELED` and return a `PATIENT_PORTAL__APPOINTMENT_IS_CANCELABLE` effect with `{"result": False}` to hide the Cancel button.
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__APPOINTMENT_CAN_BE_CANCELED)
        def compute(self) -> list[Effect]:
            return [
              Effect(
                type=EffectType.PATIENT_PORTAL__APPOINTMENT_IS_CANCELABLE,
                payload=json.dumps({"result": False}))
            ]
    ```
###  Hide 'Reschedule' button 
Respond to `PATIENT_PORTAL__APPOINTMENT_CAN_BE_RESCHEDULED` and return a `PATIENT_PORTAL__APPOINTMENT_IS_RESCHEDULABLE` effect with `{"result": False}` to hide the Reschedule button.
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__APPOINTMENT_CAN_BE_RESCHEDULED)
        def compute(self) -> list[Effect]:
            return [
              Effect(
                type=EffectType.PATIENT_PORTAL__APPOINTMENT_IS_RESCHEDULABLE,
                payload=json.dumps({"result": False}))
            ]
    ```
###  Hide 'Join' button 
This button shows on telehealth appointments. Respond to `PATIENT_PORTAL__APPOINTMENT_CAN_SHOW_MEETING_LINK` and return a `PATIENT_PORTAL__APPOINTMENT_SHOW_MEETING_LINK` effect with `{"result": True}` to show the join link.
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__APPOINTMENT_CAN_SHOW_MEETING_LINK)
        def compute(self) -> list[Effect]:
            return [
              Effect(
                type=EffectType.PATIENT_PORTAL__APPOINTMENT_SHOW_MEETING_LINK,
                payload=json.dumps({"result": True}))
            ]
    ```
##  Configuring the Patient Portal 
Return a `PatientPortalApplicationConfiguration` effect from a handler on the `PATIENT_PORTAL__GET_APPLICATION_CONFIGURATION` event to set application-level portal options. Today this controls whether the self-scheduling entry points appear; pair it with Shape Self-Scheduling to control _what_ patients can book.
Attribute| Type| Description  
---|---|---  
can_schedule_appointments| bool| If the patient is allowed to book or reschedule appointments  
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_portal.application_configuration import PatientPortalApplicationConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class MyHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__GET_APPLICATION_CONFIGURATION)
        def compute(self) -> list[Effect]:
            return [
              PatientPortalApplicationConfiguration(
                can_schedule_appointments=True
              ).apply()
            ]
    ```
##  Shape Self-Scheduling 
When patients self-schedule, you can filter or reorder what they're offered _before they see it_ — the open time slots, and the appointment-type, location, and provider options on the scheduling form. Each search step fires a `…PRE_SEARCH` event (before Canvas runs the search) and a `…POST_SEARCH` event (with the results). Respond to the `POST_SEARCH` event and return an effect **of the same name with a`_RESULTS` suffix**, carrying the results you want the patient to see. (A `…PRE_SEARCH` event is available for each step too, if you need to act before the search runs.)
Two example plugins put these together: [patient_portal_search_appointments_slots_plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_portal_search_appointments_slots_plugin) (slots) and [patient_app_schedule](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_app_schedule) (appointment types, locations, and providers).
###  Filter available slots 
Respond to `PATIENT_PORTAL__APPOINTMENTS__SLOTS__POST_SEARCH` and return `PATIENT_PORTAL__APPOINTMENTS__SLOTS__POST_SEARCH_RESULTS`.
**Target:** `self.target` is the [Patient](/sdk/data-patient/#patient) id.
**Context:** `self.context["slots_by_provider"]` — a JSON string of `{provider: {date: [{"start", "end"}, ...]}}`, keyed by [Staff](/sdk/data-staff/#staff) id, where each `start`/`end` is an ISO-8601 datetime.
Example — enforce a 48-hour minimum lead time so patients can't self-book last minute:
    ```python
    import json
    import arrow
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    # Patients must book at least this far ahead — no last-minute self-scheduling
    MIN_LEAD_TIME_HOURS = 48
    class SlotFilter(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__APPOINTMENTS__SLOTS__POST_SEARCH)
        def compute(self) -> list[Effect]:
            # slots_by_provider maps each provider to {date: [{"start": ..., "end": ...}, ...]}
            slots_by_provider = json.loads(self.context.get("slots_by_provider") or "{}")
            cutoff = arrow.now().shift(hours=MIN_LEAD_TIME_HOURS)
            filtered = {}
            for provider, dates in slots_by_provider.items():
                # drop any slot starting before the cutoff
                kept = {
                    date: [slot for slot in slots if arrow.get(slot["start"]) >= cutoff]
                    for date, slots in dates.items()
                }
                # then drop empty dates, and providers left with no slots
                kept = {date: slots for date, slots in kept.items() if slots}
                if kept:
                    filtered[provider] = kept
            return [
                Effect(
                    type=EffectType.PATIENT_PORTAL__APPOINTMENTS__SLOTS__POST_SEARCH_RESULTS,
                    payload=json.dumps({"slots_by_provider": filtered}),
                )
            ]
    ```
###  Filter appointment types 
Respond to `PATIENT_PORTAL__APPOINTMENTS__FORM_APPOINTMENT_TYPES__POST_SEARCH` and return `PATIENT_PORTAL__APPOINTMENTS__FORM_APPOINTMENT_TYPES__POST_SEARCH_RESULTS`.
**Target:** `self.target` is the [Patient](/sdk/data-patient/#patient) id.
**Context:** `self.context["appointment_types"]` — a list of `{"id", "title"}` entries, where `id` is a [NoteType](/sdk/data-note/#notetype) id (its `unique_identifier`) and `title` is the note type's name.
Example — only let patients self-book a specific set of visit types (e.g. keep follow-ups and telehealth, hide new-patient intakes):
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    # Visit types patients are allowed to self-book
    PATIENT_BOOKABLE_TYPES = {"Follow-up", "Telehealth visit"}
    class AppointmentTypeFilter(BaseHandler):
        RESPONDS_TO = EventType.Name(
            EventType.PATIENT_PORTAL__APPOINTMENTS__FORM_APPOINTMENT_TYPES__POST_SEARCH
        )
        def compute(self) -> list[Effect]:
            # each entry is {"id": ..., "title": ...}
            appointment_types = self.context.get("appointment_types", [])
            filtered = [t for t in appointment_types if t["title"] in PATIENT_BOOKABLE_TYPES]
            return [
                Effect(
                    type=EffectType.PATIENT_PORTAL__APPOINTMENTS__FORM_APPOINTMENT_TYPES__POST_SEARCH_RESULTS,
                    payload=json.dumps({"appointment_types": filtered}),
                )
            ]
    ```
###  Filter locations 
Respond to `PATIENT_PORTAL__APPOINTMENTS__FORM_LOCATIONS__POST_SEARCH` and return `PATIENT_PORTAL__APPOINTMENTS__FORM_LOCATIONS__POST_SEARCH_RESULTS`.
**Target:** `self.target` is the [Patient](/sdk/data-patient/#patient) id.
**Context:** `self.context["locations"]` — a list of `{"id", "title"}` entries, where `id` is a [PracticeLocation](/sdk/data-practicelocation/#practicelocation) id and `title` is its full name.
Example — only show locations where the patient has been seen before:
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Appointment
    class LocationFilter(BaseHandler):
        RESPONDS_TO = EventType.Name(
            EventType.PATIENT_PORTAL__APPOINTMENTS__FORM_LOCATIONS__POST_SEARCH
        )
        def compute(self) -> list[Effect]:
            locations = self.context.get("locations", [])
            seen_location_ids = {
                str(loc_id)
                for loc_id in Appointment.objects.filter(patient__id=self.target)
                .exclude(location__isnull=True)
                .values_list("location__id", flat=True)
            }
            filtered = [loc for loc in locations if loc["id"] in seen_location_ids]
            return [
                Effect(
                    type=EffectType.PATIENT_PORTAL__APPOINTMENTS__FORM_LOCATIONS__POST_SEARCH_RESULTS,
                    payload=json.dumps({"locations": filtered}),
                )
            ]
    ```
###  Filter providers 
Respond to `PATIENT_PORTAL__APPOINTMENTS__FORM_PROVIDERS__POST_SEARCH` and return `PATIENT_PORTAL__APPOINTMENTS__FORM_PROVIDERS__POST_SEARCH_RESULTS`.
**Target:** `self.target` is the [Patient](/sdk/data-patient/#patient) id.
**Context:** `self.context["providers"]` — a list of `{"id", "title"}` entries, where `id` is a [Staff](/sdk/data-staff/#staff) id and `title` is the provider's name and roles.
Example — only offer the patient's own care-team providers:
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import CareTeamMembership
    from canvas_sdk.v1.data.care_team import CareTeamMembershipStatus
    class ProviderFilter(BaseHandler):
        RESPONDS_TO = EventType.Name(
            EventType.PATIENT_PORTAL__APPOINTMENTS__FORM_PROVIDERS__POST_SEARCH
        )
        def compute(self) -> list[Effect]:
            providers = self.context.get("providers", [])
            care_team_ids = {
                str(staff_id)
                for staff_id in CareTeamMembership.objects.filter(
                    patient__id=self.target, status=CareTeamMembershipStatus.ACTIVE
                ).values_list("staff__id", flat=True)
            }
            filtered = [p for p in providers if p["id"] in care_team_ids]
            return [
                Effect(
                    type=EffectType.PATIENT_PORTAL__APPOINTMENTS__FORM_PROVIDERS__POST_SEARCH_RESULTS,
                    payload=json.dumps({"providers": filtered}),
                )
            ]
    ```
##  Forms 
Forms let you dynamically display questionnaires to patients in the portal based on your own criteria, and commit each response to the patient's chart as a Questionnaire Command when they submit. Because your handler runs on every portal page load, return only the forms that should currently appear.
> **Warning:** Set `create_command=True` on almost every form. It's what puts the patient's response in the chart — as a committed Questionnaire Command in a note. Without it, the response is saved only as an Interview and never surfaces in the chart, so the care team won't see it. Leave it off only when you have a specific reason.
Respond to the `PATIENT_PORTAL__GET_FORMS` event and return a `FormResult` effect for each questionnaire to show.
Attribute| Type| Description  
---|---|---  
`questionnaire_id`| `str` | `UUID`| The unique ID of the [Questionnaire](/sdk/data-questionnaire/#questionnaire) to show.  
`create_command`| `bool`| **Strongly recommended`True`.** Commits the response as a Questionnaire Command in a note so it appears in the chart. When `False` (the default), the response is saved only as an Interview and never appears in a note.  
`note_id`| `str` | `UUID` | `None`| The [Note](/sdk/data-note/#note) to place the command on. Only used when `create_command` is `True`; if omitted, Canvas creates and locks a new note for it. Has no effect on its own.  
**Example** — assign intake questionnaires when a patient has a confirmed upcoming visit, skipping any they've already completed:
    ```python
    import arrow
    from canvas_sdk.effects.patient_portal.form_result import FormResult
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Interview, Patient, Questionnaire
    from canvas_sdk.v1.data.appointment import AppointmentProgressStatus
    INTAKE_QUESTIONNAIRES = ["Insurance Details", "Preferred Pharmacy Details", "Social History"]
    APPOINTMENT_NOTE_TYPES = ["Telehealth", "Office visit"]
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__GET_FORMS)
        def _upcoming_appointment_note_id(self, appointments):
            return appointments.filter(
                status=AppointmentProgressStatus.CONFIRMED,
                start_time__gt=arrow.now().date(),
                note_type__name__in=APPOINTMENT_NOTE_TYPES,
            ).values_list("note__id", flat=True).first()
        def compute(self):
            patient = Patient.objects.get(id=self.target)
            # Only assign intake forms when there's a confirmed upcoming visit
            note_id = self._upcoming_appointment_note_id(patient.appointments)
            if not note_id:
                return []
            # Which intake questionnaires are already completed *on this visit's note*.
            # committed() automatically drops entered-in-error and uncommitted interviews.
            # The same intake form is expected each visit, so scope the check to this note
            # rather than the whole patient.
            completed = set(
                Interview.objects.for_patient(patient.id)
                .committed()
                .filter(note_id=note_id, questionnaires__name__in=INTAKE_QUESTIONNAIRES)
                .values_list("questionnaires__name", flat=True)
            )
            missing = [name for name in INTAKE_QUESTIONNAIRES if name not in completed]
            missing_ids = Questionnaire.objects.filter(name__in=missing).values_list("id", flat=True)
            return [
                FormResult(questionnaire_id=qid, create_command=True, note_id=note_id).apply()
                for qid in missing_ids
            ]
    ```
**Best practices:**
  - **Match questionnaires by name, not ID — it always resolves to the latest version.** When a questionnaire is updated, the previous version is archived with a `(v#)` suffix on its name (e.g. `Social History (v1)`) while the current version keeps the clean name. Filtering by the exact name therefore returns only the latest version, and (as a bonus) stays portable across instances, where IDs differ.
  - **Prevent duplicates — but scope the check.** This logic runs on every page load, so check existing committed `Interview` responses before assigning a form again. Because the same intake form is typically expected at every visit, scope that check to the current appointment's `note_id` rather than the whole patient (use `.committed()` so entered-in-error responses are ignored automatically).
  - **Don't let forms linger.** Return a questionnaire only while it should be shown; once it's completed or no longer relevant, stop returning it.
  - **Always land responses in the chart.** Set `create_command=True` so each submission is committed as a Questionnaire Command; pass a `note_id` to target a specific note, or omit it to let Canvas create one. Without `create_command`, the response is only an Interview and the care team won't see it.
Real-world example: the MSF [patient-portal-forms](https://github.com/medical-software-foundation/canvas/tree/main/extensions/patient-portal-forms) extension assigns questionnaires (PHQ-9, GAD-7, ROS…) that patients complete in the portal, posting responses back to the chart.
##  User Login 
These effects manage a patient's portal **user account** — the login they use to access the portal. Invites and password resets are sent to the email or phone linked on the user, so make sure those contact points are actually **verified** before you invite a patient or rely on an updated value. Trigger a verification with the [Send Contact Verification](/sdk/effect-send-contact-verification/) effect.
###  Update User 
The `UpdateUserEffect` updates a portal user's phone number or email. In the future this may support additional attributes, but for now only these two are supported. It isn't tied to a specific portal event — emit it from whatever handler fits your workflow (a common one is keeping the portal user in sync in response to `PATIENT_CONTACT_POINT_UPDATED`, as below).
Attribute| Type| Required| Description  
---|---|---|---  
`user_dbid`| `int`| `true`| The `dbid` of the [CanvasUser](/sdk/data-canvasuser/#user) to update.  
`phone_number`| `str`| `false`*| The phone number to store.  
`email`| `str`| `false`*| The email to store.  
**Validation:** at least one of `phone_number` or `email` must be provided, and `user_dbid` must resolve to an existing user (otherwise the effect returns a `User does not exist` error).
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.update_user import UpdateUserEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import PatientContactPoint
    from canvas_sdk.v1.data.common import ContactPointSystem
    class SyncPortalUser(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CONTACT_POINT_UPDATED)
        def compute(self) -> list[Effect]:
            contact_point = PatientContactPoint.objects.get(id=self.target)
            # Only sync verified contact points. last_verified is set once the patient
            # completes the verification challenge (see Send Contact Verification); until
            # then the value shouldn't be trusted as the account's login channel.
            if not contact_point.last_verified:
                return []
            user = contact_point.patient.user
            # Only update when the value actually changed. Emitting an effect that sets the
            # user to what it already is is a no-op — and can retrigger
            # PATIENT_CONTACT_POINT_UPDATED, causing an update loop.
            if contact_point.system == ContactPointSystem.EMAIL and user.email != contact_point.value:
                return [UpdateUserEffect(user_dbid=user.dbid, email=contact_point.value).apply()]
            if contact_point.system == ContactPointSystem.PHONE and user.phone_number != contact_point.value:
                return [UpdateUserEffect(user_dbid=user.dbid, phone_number=contact_point.value).apply()]
            return []
    ```
###  Send Invite 
The `SendInviteEffect` triggers a portal invitation that lets the patient register or activate their portal account. Because the invite is delivered to the patient's email or phone, only send it once that contact point is **verified** (`PatientContactPoint.last_verified` is set — see [Send Contact Verification](/sdk/effect-send-contact-verification/)) and the patient hasn't already registered (`CanvasUser.is_portal_registered`). Verification completes with a save that fires `PATIENT_CONTACT_POINT_UPDATED`, which makes it a natural trigger for the invite. Re-inviting someone who has already activated their account just sends a redundant email/SMS.
Attribute| Type| Required| Description  
---|---|---|---  
`user_dbid`| `int`| `true`| The `dbid` of the [CanvasUser](/sdk/data-canvasuser/#user) to invite.  
**Validation:** `user_dbid` must resolve to an existing user (otherwise the effect returns a `User does not exist` error).
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.send_invite import SendInviteEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import PatientContactPoint
    class InviteVerifiedPatient(BaseHandler):
        # Verification completes with a save that fires this event
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CONTACT_POINT_UPDATED)
        def compute(self) -> list[Effect]:
            contact_point = PatientContactPoint.objects.get(id=self.target)
            # Only invite once the contact point is actually verified — that's the
            # channel the invitation will be delivered to.
            if not contact_point.last_verified:
                return []
            user = contact_point.patient.user
            # Only invite once: skip if there's no portal user yet, or they've already registered
            if user is None or user.is_portal_registered:
                return []
            return [SendInviteEffect(user_dbid=user.dbid).apply()]
    ```

# Payment Processor

Source: https://docs.canvasmedical.com/sdk/payment-processor-effect/

These effects are returned from a custom [Payment Processor](/sdk/handlers-payment-processors/) handler in response to the `REVENUE__PAYMENT_PROCESSOR__*` [events](/sdk/events/#payment-processor-events). Each effect is the handler's reply to a specific stage of a payment workflow — advertising the processor, rendering a form, charging a card, or managing a patient's saved payment methods.
All of the classes below are importable from `canvas_sdk.effects.payment_processor`.
##  PaymentProcessorMetadata 
Advertises a payment processor to Canvas in response to `REVENUE__PAYMENT_PROCESSOR__LIST`. Canvas uses it to discover which processors are installed and to route later events (charge, add card, etc.) to the right handler.
**You normally never construct this yourself.** The base `PaymentProcessor` handler builds and returns it automatically through its `metadata()` method, which fills in:
  - `identifier` — a stable, unique id derived from your handler class (its module path and class name), exposed as `self.identifier`. Canvas includes this `identifier` in every subsequent payment processor event so your handler knows the event is meant for it.
  - `type` — the processor's `TYPE` class attribute (for example, `CardPaymentProcessor` sets this to `CARD`).
Because the base handler already responds to `REVENUE__PAYMENT_PROCESSOR__LIST` with this effect, you only need to construct it directly in advanced cases where you override that default behavior.
Attribute|  | Type| Description  
---|---|---|---  
identifier| required| String| Unique identifier of the payment processor. Generated automatically per handler.  
type| required| PaymentProcessorType| The kind of processor. Currently only `CARD` is supported.  
###  PaymentProcessorType 
Value| Description  
---|---  
`CARD`| A card-based processor.  
##  PaymentProcessorForm 
Returns the HTML form used to collect and tokenize card details, in response to `REVENUE__PAYMENT_PROCESSOR__SELECTED`. The `content` is rendered as inner HTML inside Canvas and must implement the [Form Workflow](/sdk/handlers-payment-processors/#form-workflow).
Attribute|  | Type| Description  
---|---|---|---  
intent| required| String| The purpose of the form. One of `"pay"` or `"add_card"`.  
content| required| String| The HTML content to render inside Canvas.  
    ```python
    from canvas_sdk.effects.payment_processor import PaymentProcessorForm
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    def payment_form(self, patient: Patient | None = None) -> PaymentProcessorForm:
        content = render_to_string("templates/payment_form.html")
        return PaymentProcessorForm(intent="pay", content=content)
    ```
##  CardTransaction 
Returns the result of charging a card, in response to `REVENUE__PAYMENT_PROCESSOR__CHARGE`.
Attribute|  | Type| Description  
---|---|---|---  
success| required| Boolean| Whether the charge succeeded.  
transaction_id| required| String | None| The identifier of the transaction, if one was created.  
api_response| required| Dictionary| The raw response returned by the payment provider.  
error_code| optional| String | None| An error code describing why the charge failed, if applicable.  
    ```python
    from decimal import Decimal
    from typing import Any
    from canvas_sdk.effects.payment_processor import CardTransaction
    from canvas_sdk.v1.data import Patient
    def charge(
        self, amount: Decimal, token: str, patient: Patient | None = None, **kwargs: Any
    ) -> CardTransaction:
        return CardTransaction(
            success=True,
            transaction_id="txn_123",
            api_response={"status": "succeeded"},
        )
    ```
##  PaymentMethod 
Represents a patient's saved payment method, returned in response to `REVENUE__PAYMENT_PROCESSOR__PAYMENT_METHODS__LIST`.
The cards managed by your custom processor live with your third-party payment provider — your processor is responsible for persisting them there when a card is added and deleting them when a card is removed. Canvas does not persist them for you; it asks your handler for the current list each time it needs to display saved cards, and the values you return here are rendered directly.
Attribute|  | Type| Description  
---|---|---|---  
payment_method_id| required| String| The identifier of the saved payment method.  
brand| required| String| The card brand (e.g. `"Visa"`).  
card_holder_name| required| String | None| The name of the card holder.  
expiration_year| required| Integer| The card's expiration year.  
expiration_month| required| Integer| The card's expiration month.  
card_last_four_digits| required| String| The last four digits of the card number.  
postal_code| optional| String | None| The billing postal code.

# Plugin Logs

Source: https://docs.canvasmedical.com/sdk/plugin-logs/

Canvas provides two ways to access **Plugin Logs** :
  - **UI:** `https://<your-instance>.canvasmedical.com/admin/plugin-io` → **Logs**
  - **CLI:** `canvas logs --help`
This guide explains how to open the UI view and how to use the CLI to filter, paginate, and (optionally) follow live logs.
* * *
###  Plugin Logs in the Admin UI 
From the Django Admin:
Navigation path:  
`Home` › `Plugin_IO` › **Plugin Logs**
The UI lets you:
  - Filter by **source** (e.g., `plugin-runner`, `effect-interpreter`)
  - Filter by **level** (`ERROR`, `WARN`, `INFO`, `DEBUG`)
  - Filter by **plugin** — multi-select; the dropdown is pre-populated with plugins seen in the last 7 days, and accepts free-text entries for older or yet-to-log plugins
  - Filter by **handler** — multi-select on the fully-qualified handler class; works the same as plugin (last 7 days + free-text)
  - Filter by **time** (start/end)
  - Inspect **full JSON** of a log entry in a modal
  - **Load more** results without leaving the page
The results table shows columns for `@timestamp`, `level`, `source`, `plugin`, and `message`. Click a row to open the full log entry as JSON.
> **Info:** The UI defaults to showing the most recent logs first (sorted by `@timestamp desc`).
* * *
###  CLI Overview 
`canvas logs` now supports **historical lookback** , **filters** , **stateless pagination** with **cursors** , and **interactive paging** , all without breaking the original behavior.
  - **Default (no flags)** → live stream (unchanged)
  - **Add a time window** → fetch history (tail), then **follow** by default
  - **Stop after history** → `--no-follow`
  - **Page through large result sets** → `--limit`, `--page-size`, `--interactive`, or **cursor** tokens
Run `canvas logs --help` to see all options.
###  Common Filters & Examples 
#####  Filter by source 
    ```console
    $ canvas logs --source plugin-runner
    ```
#####  Filter by level (repeat flag) 
    ```console
    # Only errors:
    $ canvas logs --level ERROR
    # Errors and warnings:
    $ canvas logs --level ERROR --level WARN
    ```
#####  Filter by plugin / handler (repeatable) 
    ```console
    # One plugin:
    $ canvas logs --plugin my_plugin
    # Multiple plugins:
    $ canvas logs --plugin my_plugin --plugin other_plugin
    # A specific handler (fully qualified class name):
    $ canvas logs --handler my_plugin.handlers.foo.MyHandler
    # Multiple handlers:
    $ canvas logs --handler my_plugin.handlers.foo.MyHandler --handler my_plugin.handlers.bar.OtherHandler
    ```
#####  Time windows: since / start / end 
**Relative lookback (`--since`)**  
Fetch the last 24 hours, then continue following:
    ```console
    $ canvas logs --since 24h
    ```
**Absolute window (`--start/--end`)**  
Fetch a fixed window and stop:
    ```console
    $ canvas logs --start "2025-09-12T10:00:00Z" --end "2025-09-12T12:00:00Z" --no-follow
    ```
> **Info:** `--since` is mutually exclusive with `--start/--end`.
#####  Combine filters 
    ```console
    # Errors from plugin-runner in the last 2 hours:
    $ canvas logs --since 2h --level ERROR --source plugin-runner --no-follow
    ```
* * *
###  Interactive Mode 
Use `--interactive` in **historical** mode to page through results one page at a time:
    ```console
    $ canvas logs --no-follow --since 24h --interactive
    # Shows one page, prompts:
    # Load more? [Y/n]
    ```
  - The prompt repeats after each page.
* * *
###  Stateless Paging with Cursors 
When more results are available, the CLI prints a **resume command** with a **cursor token** (encodes the `search_after` and original filters). Re-run it to continue exactly where you left off:
    ```console
    More available. To load the next page, run:
      canvas logs \
      --no-follow \
      --cursor <TOKEN>
    ```
> **Warning:** `--cursor` is **mutually exclusive** with filters (`--since`, `--start/--end`, `--level`, `--source`, `--plugin`, `--handler`) to enforce consistency. Use the token alone to resume
.
* * *
###  Limits & Page Size 
  - **`--page-size`** : how many logs to fetch per request (batching).  
Default is optimized for typical usage.
  - **`--limit`** : maximum number of logs to print **across pages**.
Examples:
    ```console
    # One fixed page of size 200 (default page-size):
    $ canvas logs --no-follow --since 24h
    # Fetch up to 2000 logs across pages (non-interactive):
    $ canvas logs --no-follow --since 72h --limit 2000
    # Smaller batches for slow connections:
    $ canvas logs --no-follow --since 24h --limit 1000 --page-size 100
    ```
> **Info:** In non-interactive, no-limit mode, the CLI prints **one page**. Add `--limit`, `--interactive`, or `--all` to keep paging.
* * *
###  No-Follow (Historical Only) 
Add `--no-follow` to fetch **only** historical logs and exit:
    ```console
    $ canvas logs --no-follow --since 24h
    ```

# Handlers & Protocols

Source: https://docs.canvasmedical.com/sdk/protocols/

The handlers module lets you define workflows and workflow automations. Handlers respond to [Events](/sdk/events/) and return zero, one, or many [Effects](/sdk/effects/).
`ClinicalQualityMeasure` is a specialized handler base class for clinical protocols — see ClinicalQualityMeasure below.
##  Contents 
  - BaseHandler
  - ClinicalQualityMeasure
##  BaseHandler 
`BaseHandler` is the abstract base class all handler implementations inherit from. It provides the lifecycle and surface area plugin authors implement for event-driven handlers.
###  Purpose & lifecycle 
  - The framework will call `compute()` on the handler instance when an event should be handled. `compute()` must return a list of `Effect` objects that the runtime will apply.
  - Handlers must override the `compute()` method.
###  Constructor and attributes 
  - Your handler should inherit from `BaseHandler` and define the following:
    - `RESPONDS_TO` — The `Event(s)` that trigger the handler.
    - `compute` — The method that handles the Event and returns a list of Effects.
  - Instance attributes available to handler authors:
    - `self.event` — The `Event` instance.
    - `self.secrets` — Secrets provided to the handler (defaults to {}).
###  Example 
    ```python
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.events import EventType
    from canvas_sdk.effects.task import AddTask
    class SimpleFollowUpHandler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.IMAGING_REPORT_CREATED)
        def compute(self):
            # Use self.event, self.secrets
            patient_id = self.event.context["patient"]["id"]
            imaging_report_id = self.event.target.id
            # Create a follow-up task effect
            return [AddTask(patient_id=patient_id, title="Follow-up", linked_object_type=AddTask.LinkableObjectType.IMAGING, linked_object_id=imaging_report_id).apply()]
    ```
##  ClinicalQualityMeasure 
`ClinicalQualityMeasure` is the base class for clinical quality measure (CQM) protocols. CQMs are patient-centric protocols used to evaluate, detect, or surface clinical conditions, gaps in care, and population-level metrics. Plugin authors create concrete subclasses that implement the clinical logic and return Effects in response to incoming Events.
When using `ClinicalQualityMeasure`, you have the option to utilize the [Campaigns](https://help.canvasmedical.com/articles/3097826946-campaigns-populations-patients) module in Canvas. However, the `ClinicalQualityMeasure` must return a single [`ProtocolCard`](/sdk/effect-protocol-cards/) effect in order to for patients to be included in the population for that CQM.
###  Meta properties 
Subclasses should populate the `Meta` inner class. Common meta fields include:
  - `title` (str): Human-readable title for the protocol.
  - `identifiers` (list[str]): One or more external identifiers for the measure (for example, CMS/QDM ids). These will show in the subtitle of the protocol card.
  - `description` (str): A short description of what the measure evaluates.
  - `information` (str): Longer contextual information or rationale.
  - `references` (list[str]): Links or identifiers for authoritative references. These are visible in the info button on the protocol card.
  - `source_attributes` (dict[str, str]): Map of the 13 or 31 source attributes that certified health IT developers must reference when implementing DSI or PDSI. These are visible in the info button on the protocol card.
  - `types` (list[str]): Tags or classification strings for the measure, like "CQM" or "HCC". These are visible in the subtitle of the protocol card.
  - `authors` (list[str]): Authors or maintainers of the protocol.
  - `show_in_chart` (bool): Determines whether the protocol card will show on the patient's chart.
  - `show_in_population` (bool): Determines whether the protocol will be included in the Campaigns module of Canvas.
  - `can_be_snoozed` (bool): Determines whether a user can snooze the protocol card to be addressed at a later date.
  - `is_abstract`, `is_predictive` (bool): Behavioral flags for the framework.
###  Key methods 
  - `timeframe` (property) -> `Timeframe`
    - Provides the default timeframe used by the protocol when searching for relevant events or records. The default implementation returns a timeframe with a start one year before now and an end at the current time. Subclasses can override this property to adjust the window of interest.
  - `relative_float(value: str) -> float`
    - Parses comparison-style numeric strings that may include relational prefixes like `<`, `<=`, `>` or `>=`. Returns a float adjusted slightly (±1e-6) for strict `<` or `>` operators so comparisons can be expressed without ambiguity. If parsing fails, returns `0`.
  - `patient_id_from_target()` -> str
    - Extracts and caches the patient id from a protocol event target for supported event types. The method supports a variety of patient-centric event targets (Conditions, LabOrders, LabReports, Medications, Patient create/update events, and ProtocolOverride events). The first call will fetch and cache the patient id to avoid repeated DB lookups. If an unsupported event type is provided a `ValueError` is raised.
###  Example — react to a lab report 
This example shows a protocol that reacts to `LAB_REPORT_CREATED` events, uses `patient_id_from_target` to determine which patient the report belongs to, and emits an Effect when a particular lab value is out of range. Note the example avoids heavy synchronous DB work and emits an Effect for the platform to handle asynchronously.
    ```python
    from datetime import datetime
    from canvas_sdk.commands import TaskCommand
    from canvas_sdk.effects.protocol_card import ProtocolCard
    from canvas_sdk.events import EventType
    from canvas_sdk.protocols.clinical_quality_measure import ClinicalQualityMeasure
    class AbnormalPotassiumMeasure(ClinicalQualityMeasure):
        """Detects clinically significant potassium abnormalities and surfaces follow-up tasks."""
        class Meta:
            title = "Abnormal Potassium Alert"
            identifiers = ["CQM-K-001"]
            description = "Creates a task recommendation when a potassium lab report shows hypokalemia or hyperkalemia."
            information = (
                "Detects clinically significant potassium abnormalities and surfaces follow-up tasks."
            )
            references = ["Potassium Guideline https://example.org/guideline/potassium"]
            source_attributes = {"Canvas Medical": "Canvas Medical https://www.canvasmedical.com"}
            types = ["CQM"]
            authors = ["Clinical Team"]
            show_in_chart = True
            show_in_population = True
            can_be_snoozed = False
            is_abstract = False
            is_predictive = False
        RESPONDS_TO = EventType.Name(EventType.LAB_REPORT_CREATED)
        def compute(self):
            # Resolve patient id (cached on first call)
            patient_id = self.patient_id_from_target()
            # Read the lab report values from the event target (avoid extra DB queries here)
            report = self.event.target
            potassium_value = report.get_value('potassium')  # simplified accessor
            # Use relative_float to safely parse any comparator-style values
            k = self.relative_float(str(potassium_value))
            if k < 3.5 or k > 5.5:
                # Emit an effect — e.g., create a task. Keep heavy work to platform handlers.
                task = TaskCommand(
                    title="Follow-up on abnormal potassium",
                    due_date=datetime.now().date(),
                )
                return [
                    ProtocolCard(
                        patient_id=patient_id,
                        title=f"Abnormal potassium: {k}",
                        due=datetime.now(),
                        key="abnormal_potassium",
                        narrative="Talk to patient about potassium",
                        recommendations=[task.recommend(title="Follow-up on abnormal potassium")],
                    ).apply()
                ]
            return []
    ```
![ProtocolCard]()
When a CQM protocol that returns a single ProtocolCard effect is uploaded to Canvas, you can select the protocol as an option in the Campaigns module and view the population of patients, create campaigns, etc. More details on Populations and Campaigns can be found [here](https://help.canvasmedical.com/articles/3097826946-campaigns-populations-patients).
###  Caveats & notes 
  - Timeframe: by default the protocol looks at the 1-year window prior to now. Override `timeframe` if your measure requires a broader or narrower lookback.
  - patient id resolution: `patient_id_from_target()` supports only the event types enumerated by the implementation; verify the event you plan to subscribe to maps to a supported model. When used heavily, this method avoids extra DB queries by caching the patient id on the instance.
  - Event-driven handlers should avoid expensive synchronous DB operations inside their event handler. When possible, emit Effects that are handled asynchronously by the platform.

            code: QUES_BRANCH_Q1_YES
          - name: "No"
            code: QUES_BRANCH_Q1_NO
      - content: "Please describe your allergies"
        code_system: INTERNAL
        code: QUES_BRANCH_Q2
        responses_code_system: INTERNAL
        responses_type: TXT
        enabled_conditions:
          - question_code: QUES_BRANCH_Q1
            operator: "="
            value_code: QUES_BRANCH_Q1_YES
        responses:
          - name: "TXT"
            code: QUES_BRANCH_Q2_A1
      - content: "How severe are your allergies?"
        code_system: INTERNAL
        code: QUES_BRANCH_Q3
        responses_code_system: INTERNAL
        responses_type: SING
        enabled_behavior: all
        enabled_conditions:
          - question_code: QUES_BRANCH_Q1
            operator: "="
            value_code: QUES_BRANCH_Q1_YES
          - question_code: QUES_BRANCH_Q2
            operator: exists
        responses:
          - name: "Mild"
            code: QUES_BRANCH_Q3_MILD
          - name: "Moderate"
            code: QUES_BRANCH_Q3_MODERATE
          - name: "Severe"
            code: QUES_BRANCH_Q3_SEVERE
    ```
In this example:
  - **Q1** is always visible.
  - **Q2** only appears if Q1 is answered "Yes" (using `=` with `value_code`).
  - **Q3** only appears if Q1 is "Yes" **and** Q2 has been answered (using `enabled_behavior: all` with two conditions).
##  Load Questionnaire definition from YAML file 
You can use the `questionnaire_from_yaml` function from `canvas_sdk.questionnaires` within your plugin to load a questionnaire definition from a YAML file. The function takes the path to the YAML file as an argument and returns a dictionary containing the questionnaire definition.
    ```python
    def questionnaire_from_yaml(questionnaire_name: str, **kwargs):
        """Load a Questionnaire configuration from a YAML file.
        Args:
            questionnaire_name (str): The path to the questionnaire file, relative to the plugin package.
                If the path starts with a forward slash ("/"), it will be stripped during resolution.
            kwargs (Any): Additional keyword arguments.
        Returns:
            QuestionnaireConfig: The loaded Questionnaire configuration.
        Raises:
            FileNotFoundError: If the questionnaire file does not exist within the plugin's directory
                or if the resolved path is invalid.
            PermissionError: If the resolved path is outside the plugin's directory.
            ValidationError: If the questionnaire file does not conform to the JSON schema.
        """
    ```

# Sandboxing and Allowed Imports

Source: https://docs.canvasmedical.com/sdk/sandboxing-and-allowed-imports/

Plugins developed with the Canvas SDK operate within a sandboxed environment. This sandbox strictly limits access to the host operating system, filesystem, and database.

##  Canvas SDK Modules 
All Canvas SDK modules are available for import and use within your plugins:
  - `canvas_sdk.caching`
  - `canvas_sdk.commands`
  - `canvas_sdk.effects`
  - `canvas_sdk.events`
  - `canvas_sdk.handlers`
  - `canvas_sdk.protocols`
  - `canvas_sdk.questionnaires`
  - `canvas_sdk.templates`
  - `canvas_sdk.utils`
  - `canvas_sdk.v1.data`
  - `canvas_sdk.value_set`
  - `canvas_sdk.views`
  - `logger`
##  Builtin Functions 
The following Python builtin functions are available within the sandbox:
  - `all`
  - `any`
  - `classmethod`
  - `dict`
  - `enumerate`
  - `extract_exc_frames`
  - `filter`
  - `getattr`
  - `hasattr`
  - `iter`
  - `list`
  - `map`
  - `max`
  - `min`
  - `next`
  - `property`
  - `reversed`
  - `staticmethod`
  - `sum`
  - `super`
  - `vars`
On top of those, the sandbox inherits RestrictedPython's safe builtins. That covers the basic types (`bool`, `bytes`, `complex`, `float`, `frozenset`, `int`, `set`, `slice`, `str`, `tuple`), the common functions (`abs`, `callable`, `chr`, `divmod`, `hash`, `hex`, `id`, `isinstance`, `issubclass`, `len`, `oct`, `ord`, `pow`, `range`, `repr`, `round`, `sorted`, `zip`), and most of the standard exception classes.
###  Builtins that are not available 
What you see above is the whole set. The sandbox works from an allow-list rather than a list of banned names, so any builtin not mentioned there raises `NameError` when your plugin runs — including builtins that future Python releases introduce.
These are the ones plugin authors reach for most often:
Not available| Use instead  
---|---  
`eval`, `exec`, `compile`| Write the logic directly. The sandbox cannot run code it never reviewed.  
`open`, `input`| Neither the filesystem nor a console is reachable from a plugin.  
`print`| `log` from `logger`. `print` is also a reserved name.  
`type`| `isinstance(x, SomeClass)` to test a type, `x.__class__.__name__` to read its name.  
`dir`, `globals`, `locals`| Nothing. Namespace introspection is a sandbox-escape route.  
`bytearray`| `bytes` for binary data.  
One group is easy to miss: the `OSError` subclasses, including `TimeoutError`, `ConnectionError`, `FileNotFoundError`, and `PermissionError`. Writing `except TimeoutError:` around an HTTP call raises `NameError`. Catch `OSError` instead — it is available, and it matches every one of them:
    ```python
    from canvas_sdk.utils import Http
    client = Http()
    try:
        response = client.get("https://example.com/api")
    except OSError:
        # OSError is the shared base class, so this catches TimeoutError,
        # ConnectionError, and the rest of the family.
        pass
    ```
##  Forbidden Constructs 
Beyond the import allow-list above, a few Python constructs compile under RestrictedPython but are rejected when your code runs in the sandbox. `canvas validate` catches these statically before you install, so you don't have to wait for a runtime failure on the instance.
Construct| Why it's rejected| Use instead  
---|---|---  
`setattr(obj, "x", value)`| Dynamic attribute assignment is blocked| Direct assignment: `obj.x = value`  
`delattr(obj, "x")`| Dynamic attribute deletion is blocked| `del obj.x`  
`bytearray(...)`| Not available in the sandbox| `bytes` for binary data  
`type(name, bases, dict)`| Dynamic class creation (3-argument `type`) is not available| Declare the class normally with `class …:`  
`obj.attr += v`| Augmented assignment to an attribute is rejected, including on classes you defined yourself| Explicit reassignment: `obj.attr = obj.attr + v`  
`d[k] += v`| Augmented assignment to a dict item, list item, or slice is rejected| Explicit reassignment: `d[k] = d[k] + v`  
Augmented assignment to a plain variable is fine — `count += 1`, `total *= 2`, and the rest of the `-=` / `*=` / `//=` / `%=` / `**=` / `&=` / `|=` / `^=` / `<<=` / `>>=` family all work. It is only the attribute and item forms above that are rejected, and both fail when the plugin is compiled, so you find out at install time rather than mid-request.
> **Warning:** `type` is not available in the sandbox _at all_ , including the one-argument `type(x)` form used to check an object's type — it raises `NameError: name 'type' is not defined`. Use `isinstance(x, SomeClass)` to test a type, or `x.__class__.__name__` to read its name.
> **Info:** `@dataclass(frozen=True)` and `@dataclass(slots=True)` load and run fine in the sandbox — they are not forbidden.
###  `extract_exc_frames()`
A sandbox-provided function that extracts frame information from the current exception's traceback. Must be called from within an `except` block. Returns an empty list if no exception is active.
Each frame exposes only safe attributes:
  - `filename` — the file path
  - `lineno` — the line number
  - `name` — the function name
Source code lines and local variables are not accessible.
    ```python
    from logger import log
    try:
        raise Exception("some failed operation")
    except Exception:
        frames = extract_exc_frames()
        for frame in frames:
            log.info(f"{frame.filename}:{frame.lineno} in {frame.name}")
    ```
##  Runtime Restrictions 
The sandbox enforces the rules in this section every time an attribute is read or written, so they surface as an `AttributeError` while your plugin is running. That is what separates them from the forbidden constructs, which are rejected when your code is compiled and reported by `canvas validate` before you install. Nothing described here is caught until the code executes.
Throughout this section, **your plugin's code** means modules inside your own plugin package. **External code** means everything else — the Canvas SDK, the standard library, and third-party modules.
###  Reading attributes 
Attribute names that begin with an underscore are restricted, and the rule depends on where the object came from:
Object defined in| `_single_underscore`| `__dunder__`  
---|---|---  
Your plugin's code| Readable| Only names on the allow-list below  
External code| Blocked| Only names on the allow-list below  
The dunder allow-list is the same in both cases:
  - `__annotations__`
  - `__args__`
  - `__class__`
  - `__dict__`
  - `__eq__`
  - `__init__`
  - `__members__`
  - `__name__`
  - `__origin__`
  - `__traceback__`
Two of those return a restricted stand-in rather than the real object:
  - **`__class__`** on an object defined outside your plugin returns a read-only proxy that exposes only `__name__`. This is what prevents `__class__.__mro__` and `__class__.__subclasses__()` from being used to reach code outside the sandbox.
  - **`__traceback__`** returns a safe traceback exposing only `tb_frame`, `tb_lineno`, and `tb_next`. Its frame exposes only `f_code`, and that code object exposes only `co_filename` and `co_name`. Local and global variables are never reachable. `extract_exc_frames()` is the more convenient way to read a traceback.
Reading a plain attribute off an imported module is also limited to that module's entry in the allow-list at the top of this page. `json.dumps` works because `dumps` is listed under `json`; `json.tool` raises an `AttributeError`.
###  Reading items 
Subscripting with a string key that starts with an underscore is blocked on every object, including dictionaries you created yourself:
    ```python
    config = {"timeout": 30, "_internal": True}
    config["timeout"]    # fine
    config["_internal"]  # AttributeError
    ```
###  Writing attributes 
You can set attributes on modules that belong to your plugin. Setting an attribute on any other module is blocked.
For objects, whether a write is allowed depends on where the object's class was defined:
  - **Class defined in your plugin's code** — writable, including attributes that are not methods.
  - **Class defined in external code** — the write is blocked if any of the following is true:
    - the name you are assigning through was brought in by an `import`
    - the attribute currently holds a callable, so the assignment would replace a method
    - the target is a dictionary and the key is a string starting with an underscore
    ```python
    class MyThing:
        """Defined in your plugin, so its instances are writable."""
        def __init__(self) -> None:
            self.count = 0
    thing = MyThing()
    thing.count = 1       # fine
    thing.label = "new"   # fine
    ```
###  Reserved names 
These four names cannot be used for a function, variable, class, or argument anywhere in your plugin:
  - `print`
  - `printed`
  - `builtins`
  - `breakpoint`
`print` is among them, so use the SDK logger for output:
    ```python
    from logger import log
    log.info("plugin started")
    ```
###  Introspection attributes 
The attributes the `inspect` module relies on are unavailable, because they expose frames, globals, and raw bytecode:
`co_code`, `cr_await`, `cr_code`, `cr_frame`, `cr_origin`, `f_back`, `f_builtins`, `f_code`, `f_generator`, `f_globals`, `f_locals`, `f_trace`, `gi_code`, `gi_frame`, `gi_yieldfrom`, `tb_frame`, `tb_next`
The safe traceback wrappers under reading attributes are the one exception: they re-expose `tb_frame`, `tb_next`, and `f_code` through an explicit allow-list, stripped down to the fields listed there.
###  String formatting 
The `format` and `format_map` methods of `str` are not available. Use an f-string or the `%` operator instead:
    ```python
    name = "Canvas"
    greeting = f"Hello {name}"       # fine
    greeting = "Hello %s" % name     # fine
    greeting = "Hello {}".format(name)  # NotImplementedError
    ```
###  `__exports__`
Some SDK objects declare an `__exports__` attribute listing exactly which attribute names may be read from them. Where it is present it takes precedence over the other rules in this section: names in the list are readable, and anything else raises an `AttributeError`.
> **Info:** These rules are enforced by `plugin_runner/sandbox.py` in the [Canvas Plugins repository](https://github.com/canvas-medical/canvas-plugins), which is the authoritative reference if you hit a restriction that isn't described here.
##  Requesting Additional Imports 
If there is a library or function not on this list that you wish to import in your plugin, reach out on the [Canvas developer forum](https://github.com/canvas-medical/canvas-plugins/discussions). Additional imports can often be added after a security review.
The allowed imports are defined in the [Canvas Plugins repository](https://github.com/canvas-medical/canvas-plugins/blob/main/plugin_runner/sandbox.py) and are regularly updated to support common development needs while maintaining security.
##  Policy on Vendor-Specific Libraries: 
The current policy strongly discourages the inclusion of vendor-specific libraries. Introducing such libraries presents several challenges:
  - Vendor Prioritization: It risks implicitly favoring one vendor over others, which can be problematic in a multi-vendor ecosystem.
  - Dependency Bloat: Incorporating libraries for each vendor within a specific category (e.g., AI model providers like OpenAI, Anthropic) leads to a significant increase in overall dependencies.
##  Technical Implications of Excessive Dependencies: 
Adding a multitude of vendor-specific libraries can result in:
  - Increased Memory Usage: Each additional library contributes to the application's memory footprint.
  - Dependency Conflicts: Different libraries may require different versions of shared dependencies, leading to versioning conflicts and system instability.
Given these considerations, the platform maintains a strict and judicious approach to approving and incorporating external libraries or imports.

# Managing Variables

Source: https://docs.canvasmedical.com/sdk/secrets/

Canvas provides a secure key-value store that lets your plugins access configuration data — including sensitive secrets such as API tokens — without hardcoding values into source files. Configuration values are declared in your plugin's `CANVAS_MANIFEST.json` as **variables** , set at install time or through the Admin UI, and read from `self.secrets` at runtime.
Each variable can be marked **sensitive** (treated like a secret: not displayed in admin or CLI listings) or **non-sensitive** (a regular configuration value, displayed in plaintext for verification). All variable values are write-only through the CLI and API.
###  Declaring Variables in `CANVAS_MANIFEST.json`
Variables are declared in your plugin's `CANVAS_MANIFEST.json` file under the top-level `variables` field. Each variable is an object with a `name` and an optional `sensitive` flag (defaults to `false`). Variables marked as `sensitive: true` are write-only and behave like secrets. These declared variables become available for configuration in the Canvas Admin UI when the plugin is installed.
    ```json
    {
      "sdk_version": "0.1.4",
      "plugin_version": "0.0.1",
      "name": "live_notifications",
      "description": "Edit the description in CANVAS_MANIFEST.json",
      "components": {
        "handlers": [
          {
            "class": "live_notifications.handlers.my_handler:Handler",
            "description": "A handler that does xyz..."
          }
        ]
      },
      "variables": [
        {"name": "API_TOKEN", "sensitive": true},
        {"name": "WEBHOOK_URL"},
        {"name": "LOG_LEVEL", "sensitive": false}
      ],
      "tags": {}
    }
    ```
Field| Type| Required| Description  
---|---|---|---  
`name`| string| Yes| The variable name used in your plugin code  
`sensitive`| boolean| No| When `true`, marks the variable as sensitive for display purposes (default: `false`)  
####  Legacy `secrets` array (deprecated) 
The flat `secrets` array is still accepted for backwards compatibility:
    ```json
    "secrets": ["API_TOKEN"]
    ```
It emits a deprecation warning during `canvas validate-manifest` and is mapped internally to `variables` entries with `sensitive: false`. To preserve sensitive treatment, migrate to the `variables` schema with `sensitive: true` and re-install the plugin.
> **Warning:** **Deprecation Notice:** The legacy `secrets` array format is deprecated. Use the `variables` format shown above instead. The legacy format will continue to work but displays a deprecation warning during `canvas validate-manifest`.
> ⚠️ **Pre-existing values default to non-sensitive.** Any plugin secret that existed before Canvas 1.305.0 — or any value configured via the legacy `secrets:` array — is stored with `sensitive: false`. It will appear in plain text in the Admin UI until the owning plugin is migrated to the `variables` schema with `sensitive: true` and re-installed.
###  Configuring Variables from the CLI 
Set values during install or update them later. Use `--variable` for non-sensitive values and `--secret` for sensitive values; both flags accept `KEY=value` pairs.
Provide values during install:
    ```console
    $ canvas install <plugin_name> --secret API_TOKEN=your_api_token_value --variable LOG_LEVEL=info
    ```
Update values on an installed plugin:
    ```console
    $ canvas config set <plugin_name> API_TOKEN=abc123 LOG_LEVEL=warn
    ```
Pass multiple values by repeating the flag:
    ```console
    $ canvas install <plugin_name> \
      --secret API_TOKEN=abc123 \
      --secret WEBHOOK_SECRET=xyz \
      --variable LOG_LEVEL=info
    ```
####  Listing configured values 
Run `canvas config list <plugin_name>` to see which variables are configured for a plugin. Each variable is rendered as `[set]` or `[not set]`, with a `(sensitive)` annotation for sensitive variables. Values themselves are never displayed in the listing.
    ```console
    $ canvas config list my_plugin
      API_TOKEN  [set]  (sensitive)
      LOG_LEVEL  [not set]
    ```
To read a value, use the Django Admin UI (access is gated by managing-user permissions).
> _The`--variable` flag, `canvas config list` sensitive marking, and Admin UI masking require Canvas CLI 0.146.0 or newer. Upgrade with `pip install --upgrade canvas`._
###  Configuring Variables in the Admin UI 
After install you can also set values through the Admin interface.
Navigation path: `Home` › `Plugin_IO` › `Plugins` › `(your plugin)`
Or, go directly to:
    https://<your_canvas_instance>/admin/plugin_io/plugin/<plugin_id>/change/
On this page, you will find input fields for each variable defined in your manifest. Sensitive values display as `SENSITIVE` and are no longer rendered in the form HTML — submit a new value to overwrite, or leave the field blank to keep the existing value. Non-sensitive values display their current value and can be edited inline.
![Setting plugin variables](/assets/images/sdk/secrets/plugins_secrets_settings_with_permissions.png)
Sensitive variables can be protected by managing user permissions. Only users explicitly assigned as "managing users" for a plugin can view or modify its sensitive variables (as well as other sensitive settings like the plugin package file download link). Other users can see basic plugin details and enable or disable plugins, but they will not be able to access or change sensitive variable values. To add or remove managing users for a plugin, use the "Managing users" section on the plugin detail page in the Admin UI. This ensures that sensitive configuration, such as API tokens, remains visible only to authorized personnel.
###  Accessing Variables in Your Plugin 
All variables — sensitive and non-sensitive alike — are exposed to your plugin code through `self.secrets`, a Python dictionary keyed by variable name:
    ```python
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect
    class MyHandler(BaseHandler):
        def compute(self) -> list[Effect]:
            api_token = self.secrets["API_TOKEN"]
            webhook_url = self.secrets["WEBHOOK_URL"]
            log_level = self.secrets["LOG_LEVEL"]
            ...
    ```
This access pattern is unchanged from earlier Canvas versions, so migrating a plugin from the legacy `secrets:` array to the new `variables:` schema requires no handler code changes.

# SSO Capabilities

Source: https://docs.canvasmedical.com/sdk/sso/

Canvas supports SAML 2.0 single sign-on, and exposes hooks that let plugins participate in the post-login flow. Use these hooks to capture data from the identity provider's SAML response, or to send a user to a custom landing page after they authenticate.
Both hooks fire after the SAML assertion has been validated and the user has been logged in. The user's identity is available as [`self.event.actor`](/sdk/events/#event-actor); the SAML response data is available in `self.event.context`.
##  Hooks at a glance 
Hook| Type| Purpose  
---|---|---  
`SSO__PROCESS_ADDITIONAL_REQUEST_DATA`| Event| Read-only access to the SAML response so a plugin can capture IdP attributes (group memberships, employee ID, etc.).  
`SSO__GET_POST_LOGIN_REDIRECT`| Event| Override the URL the user lands on after SSO login.  
`REDIRECT_CONTEXT`| Effect| The effect returned from `SSO__GET_POST_LOGIN_REDIRECT` to set the post-login destination.  
##  `SSO__PROCESS_ADDITIONAL_REQUEST_DATA`
Fires once per successful SAML login, immediately after the user is authenticated. The event is **read-only** : any effects a handler returns are discarded. Use it for side-effects such as syncing IdP attributes onto a [`Staff`](/sdk/data-staff/) record, writing an audit log, or notifying an external system that a user signed in.
###  Context 
Key| Type| Description  
---|---|---  
`session_info`| dict| The validated SAML response data from pysaml2. Common keys include `name_id` (the SAML NameID), `issuer` (IdP entity ID), `ava` (a dict of IdP-supplied user attributes keyed by attribute name with list-valued entries), `session_index`, `not_on_or_after`, and `authn_info`.  
###  Target 
The Canvas user that just logged in. `self.event.target` resolves to a [`Staff`](/sdk/data-staff/) or [`Patient`](/sdk/data-patient/) via `self.event.actor.instance.person_subclass`.
###  Example 
    ```python
    import json
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from logger import log
    class CaptureSSOAttributes(BaseHandler):
        """Log the IdP-supplied group memberships for every SSO login."""
        RESPONDS_TO = EventType.Name(EventType.SSO__PROCESS_ADDITIONAL_REQUEST_DATA)
        def compute(self):
            session_info = json.loads(self.event.context)["session_info"]
            groups = session_info.get("ava", {}).get("groups", [])
            log.info(f"SSO login for {session_info['name_id']} with groups={groups}")
            return []
    ```
##  `SSO__GET_POST_LOGIN_REDIRECT`
Fires once per successful SAML login, right before Canvas decides where to send the user. A plugin that returns a `REDIRECT_CONTEXT` effect sets the destination URL; if no plugin returns one (or the value is falsy), Canvas falls back to its default post-login redirect.
Only the first `REDIRECT_CONTEXT` effect returned is used. If multiple plugins register a handler, ordering between them is not guaranteed — coordinate across plugins to avoid conflicting redirects.
###  Context 
Key| Type| Description  
---|---|---  
`relay_state`| str| The SAML `RelayState` value from the original login request, if any. Often used by IdPs to encode a "deep link" — the URL the user was trying to reach before they were bounced to the IdP.  
`session_info`| dict| Same shape as for `SSO__PROCESS_ADDITIONAL_REQUEST_DATA`.  
###  Target 
Same as `SSO__PROCESS_ADDITIONAL_REQUEST_DATA` — the Canvas user that just logged in.
###  Example 
    ```python
    import json
    from canvas_generated.messages.effects_pb2 import EffectType
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class RouteSSOByGroup(BaseHandler):
        """Send admins to the admin app and everyone else to the schedule."""
        RESPONDS_TO = EventType.Name(EventType.SSO__GET_POST_LOGIN_REDIRECT)
        def compute(self):
            session_info = json.loads(self.event.context)["session_info"]
            groups = session_info.get("ava", {}).get("groups", [])
            if "canvas-admins" in groups:
                url = "/admin/"
            else:
                url = "/schedule/"
            return [
                Effect(
                    type=EffectType.REDIRECT_CONTEXT,
                    payload=json.dumps({"url": url}),
                )
            ]
    ```
##  `REDIRECT_CONTEXT`
The effect that carries the post-login URL back to Canvas. It is only meaningful when returned from a `SSO__GET_POST_LOGIN_REDIRECT` handler.
###  Payload 
Key| Type| Description  
---|---|---  
`url`| str| The URL Canvas should redirect the user to after SSO login. Relative paths (e.g. `/schedule/`) and absolute URLs are both accepted.  
There is no SDK helper class for this effect — construct it directly with `Effect(type=EffectType.REDIRECT_CONTEXT, payload=json.dumps({"url": ...}))` as shown in the example above.

# Testing Utilities

Source: https://docs.canvasmedical.com/sdk/testing-utils/

Canvas SDK provides a streamlined testing environment and local database support to help developers test their plugins with real data.
This guide covers two key capabilities:
  1. Plugin testing with pytest — `canvas[test-utils]` introduces a set of tools and dependencies for writing database-backed tests.
  2. Database seeding in CLI — populate or reset your local database when running plugins locally.
* * *
##  Project Structure 
The recommended layout for plugin development is now scaffolded automatically by the `canvas init` command. This structure ensures compatibility with Canvas testing tools and CLI features, and it's strongly encouraged for all new plugin projects. We also recommend to use [`uv`](https://docs.astral.sh/uv/getting-started/installation/) for managing dependencies.
    ```bash
    plugin-folder/
    ├── my_plugin/
    │   └── ...
    ├── tests/
    │   ├── __init__.py
    │   └── test_example.py
    └── pyproject.toml
    ```
##  Plugin Testing with Pytest 
Installing the `test-utils` extra provides everything needed to test plugins with pytest.
###  Features 
  - `pytest` with `factoryboy` style fixtures
  - Each test is wrapped in a transaction and rolled back automatically.
  - Use actual models or prebuilt factories to generate test data.
  - No need for mocks or fake database layers.
###  Installation 
Add the following to your `pyproject.toml`:
    ```toml
    [project]
    name = "canvas-plugins"
    version = "0.1.0"
    requires-python = ">=3.11,<3.13"
    dependencies = [
        "canvas[test-utils]",
        # other dependencies...
    ]
    ```
or install directly via `uv`:
    ```bash
    uv add "canvas[test-utils]"
    ```
You can now run your test suite using:
    ```bash
    uv run pytest
    ```
###  Using Factories 
Factories simplify test data creation and follow the [`factory_boy`](https://factoryboy.readthedocs.io/en/stable/) pattern.
    ```python
    from canvas_sdk.test_utils.factories import PatientFactory
    def test_factory() -> None:
        patient = PatientFactory.create()
        assert patient.id is not None
    ```
###  Using Models Directly 
You can also create records manually using the model classes:
    ```python
    from canvas_sdk.v1.data.discount import Discount
    def test_model() -> None:
        Discount.objects.create(
            name="10%",
            adjustment_group="30",
            adjustment_code="CO",
            discount=0.10,
        )
        assert Discount.objects.first().pk is not None
    ```
> Whether using a factory or model directly, your test will run inside a transaction and automatically roll back at the end.
###  Available Factories 
All factories are available from:
    ```python
    from canvas_sdk.test_utils import factories
    ```
Developers are encouraged to add new factories for their own models, and to submit PRs with contributions.
At this time, Canvas has factory support for the following models:
  - Claim
  - Claim Diagnosis Code
  - Facility
  - Medication History
  - Note
  - Organization
  - Patient
  - PracticeLocation
  - ProtocolCurrent
  - Staff
  - User
A complete list of available factories is located [here](https://github.com/canvas-medical/canvas-plugins/tree/main/canvas_sdk/test_utils/factories).
##  Local DB Seeding via `run-plugin`
You can run plugins locally with full access to the database using the CLI. Two options are available:
Option| Description  
---|---  
`--db-seed-file`| Path to a Python file that populates your database. _Warning_ : It resets the database before running the seed file.  
`--reset-db`| Clears and recreates the database before running the plugin  
###  Seed the Database 
To seed your plugin's database with test data:
    ```bash
    canvas run-plugin my_plugin --db-seed-file ./seed.py
    ```
Example `seed.py`:
    ```python
    from canvas_sdk.test_utils.factories import PatientFactory
    from canvas_sdk.v1.data.discount import Discount
    PatientFactory.create(first_name="Seeded", last_name="Patient")
    Discount.objects.create(
        name="20%",
        adjustment_group="X",
        adjustment_code="Y",
        discount=0.20
    )
    ```
###  Reset the Database 
To reset the database before running a plugin:
    ```bash
    canvas run-plugin my_plugin --reset-db
    ```
This will remove the existing database (if present) and recreate a clean version.
###  Simulate Events 
After your database is set up, simulate incoming events with:
    ```bash
    canvas emit
    ```
Run `canvas emit --help` for more info.

# Utils

Source: https://docs.canvasmedical.com/sdk/utils/

##  Making requests with Http 
The Canvas SDK offers a helper class for completing HTTP calls.
    ```python
    from canvas_sdk.utils import Http
    http = Http()
    ```
###  get 
Sends a GET request.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`url`|  _string_| `true`| The url of the request.  
`headers`|  _dict_| `false`| The headers to include in the request.  
**Example** :
    ```python
    from canvas_sdk.utils import Http
    http = Http()
    http.get("https://my-url.com/", headers={"Authorization": f"Bearer token"})
    ```
###  post 
Sends a POST request.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`url`|  _string_| `true`| The url of the request.  
`headers`|  _dict_| `false`| The headers to include in the request.  
`json`|  _dict_| `false`| The json to include in the request.  
`data`|  _dict_ or _string_| `false`| The data to include in the request.  
**Example** :
    ```python
    from canvas_sdk.utils import Http
    http = Http()
    http.post(
        "https://my-url.com/",
        headers={"Authorization": f"Bearer token"},
        json={"post": "json"},
        data="this-is-my-data"
    )
    ```
###  put 
Sends a PUT request.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`url`|  _string_| `true`| The url of the request.  
`headers`|  _dict_| `false`| The headers to include in the request.  
`json`|  _dict_| `false`| The json to include in the request.  
`data`|  _dict_ or _string_| `false`| The data to include in the request.  
**Example** :
    ```python
    from canvas_sdk.utils import Http
    http = Http()
    http.put(
        "https://my-url.com/",
        headers={"Authorization": f"Bearer token"},
        json={"put": "json"},
        data="this-is-my-data"
    )
    ```
###  patch 
Sends a PATCH request.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`url`|  _string_| `true`| The url of the request.  
`headers`|  _dict_| `false`| The headers to include in the request.  
`json`|  _dict_| `false`| The json to include in the request.  
`data`|  _dict_ or _string_| `false`| The data to include in the request.  
**Example** :
    ```python
    from canvas_sdk.utils import Http
    http = Http()
    http.patch(
        "https://my-url.com/",
        headers={"Authorization": f"Bearer token"},
        json={"patch": "json"},
        data="this-is-my-data"
    )
    ```
##  Making concurrent requests with Http 
There is an interface for executing HTTP requests in parallel.
The `batch_requests` method will execute the requests in parallel using multithreading, and return once all the requests have completed.
The first parameter to the method is an iterable of `BatchableRequest` objects. These can be created with the following helper functions:
    batch_get
    batch_post
    batch_put
    batch_patch
The parameters that these helper functions accept match what the corresponding single-request methods accept.
The `timeout` parameter allows for specifying a timeout value in seconds; if a request has not completed before the timeout value, an error will be returned for that request. The maximum allowed value for `timeout` is 30 seconds. If `timeout` is not specified, it will be set to the maximum value.
The return value will be a list of responses to the requests. The order of the return value will correspond to the order of the provided requests.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`batch_requests`|  _Iterable[BatchableRequest]_| `true`| The list of batched requests.  
`timeout`|  _integer_| `false`| The timeout value in seconds.  
**Example** :
    ```python
    from canvas_sdk.utils import Http, batch_get, batch_post, batch_put, batch_patch
    http = Http()
    requests = [
        batch_get("https://my-url.com/", headers={"Authorization": f"Bearer token"}),
        batch_post("https://my-url.com/", headers={"Authorization": f"Bearer token"}, json={"post": "json"}),
        batch_put("https://my-url.com/", headers={"Authorization": f"Bearer token"}, data="this-is-my-data"),
        batch_patch("https://my-url.com/", headers={"Authorization": f"Bearer token"}, json={"patch": "json"})
    ]
    responses = http.batch_requests(requests, timeout=10)
    ```
##  Generating PDFs 
Plugin authors can generate PDFs using the `pdf_generator` client. There are two approaches: generating from a URL that serves HTML, or generating directly from an HTML string. Both methods upload the resulting PDF to S3 and return a presigned URL.
    ```python
    from canvas_sdk.utils.pdf import pdf_generator
    ```
The client exposes only `from_url` and `from_html`. Direct HTTP methods (get, post, put, patch) are not available.
###  from_url 
Generates a PDF from a URL that returns HTML. The service fetches the HTML from the given URL, converts it to PDF, uploads it to S3, and returns a presigned URL.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`print_url`|  _string_| `true`| The path to the HTML endpoint.  
`auth`|  _PdfAuthRequest_| `false`| Credentials forwarded to the PDF service so it can fetch authenticated endpoints.  
**Returns** : `PdfUrlResponse | None` — `None` if PDF generation failed.
When using `from_url`, the PDF service fetches the HTML from your endpoint directly. If that endpoint requires authentication, the SimpleAPI serving the HTML should use [`BasicAuthMixin`](/sdk/handlers-simple-api-http/#authentication-mixins) and pass the credentials via `PdfAuthRequest`.
**Example** :
    ```python
    from canvas_sdk.utils.pdf import PdfAuthRequest, pdf_generator
    # The PDF service will fetch this endpoint to get the HTML.
    # Because the endpoint uses BasicAuthMixin, we pass credentials
    # so the service can authenticate on our behalf.
    auth = PdfAuthRequest(
        username="user",
        password="password",
    )
    response = pdf_generator.from_url(
        print_url="plugin-io/api/my_plugin/printout/html?note_uuid=abc-123",
        auth=auth,
    )
    if response and response.url:
        # response.url is a presigned S3 URL to the generated PDF
        pdf_url = response.url
    ```
###  from_html 
Generates a PDF from a raw HTML string. Use this when you already have the HTML content and don't need the service to fetch it from a URL.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`content`|  _string_| `true`| The HTML content to convert.  
**Returns** : `PdfUrlResponse | None` — `None` if PDF generation failed.
**Example** :
    ```python
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.utils.pdf import pdf_generator
    html = render_to_string("templates/note_printout.html", {
        "patient_name": "Jane Doe",
        "note_type": "Office Visit",
    })
    response = pdf_generator.from_html(content=html)
    if response and response.url:
        pdf_url = response.url
    ```
###  PdfUrlResponse 
Both methods return a `PdfUrlResponse` on success, or `None` on failure.
Attribute| Type| Description  
---|---|---  
`url`|  _string_|  Presigned S3 URL to the generated PDF.  
###  Choosing between the two methods 
Use case| Method  
---|---  
Plugin serves an HTML page via SimpleAPI that requires authentication| `from_url` with `PdfAuthRequest`  
You already have the HTML string in memory (e.g. from `render_to_string`)| `from_html`  
##  Making requests to the Ontologies service 
Plugin authors can make requests to our Ontologies service using the `ontologies_http` wrapper.
In addition to the `json()` method of the response, which you'll use to access the response itself, you can also access the `status_code` to verify that the request was succcessful.
> **Use these endpoints for chart-parity lookups.** The medication and allergen search endpoints below back the autocompletes providers use in the chart. Use them — not the FHIR `/Medication` or `/Allergen` search endpoints — when you need a code that will resolve when used in a command. FHIR `/Medication` and `/Allergen` search different, narrower interoperability catalogs and can return codes the chart can't resolve (or omit ones it can); a code returned by the endpoints below resolves consistently with what the picker shows.
> **Tip:** The Medical Software Foundation's [`coding_lookup`](https://github.com/Medical-Software-Foundation/canvas/tree/main/data-migrations/data_migrations/plugins/coding_lookup) reference plugin wraps the medication and allergen lookups below as ready-made SimpleAPI endpoints (`/medication_search`, `/allergy_search`) returning a clean `{count, results}` shape. Install it as-is, or use it as a template for calling `ontologies_http` from your own plugin.
###  Searching for medications 
Plugin authors can search for medications by NDC code, RxNorm RXCUI, FDB code, or full-text search.
####  `fdb_code`
Elsewhere in the SDK there are commands that take an `fdb_code` or `new_fdb_code`, some examples being [`AdjustPrescriptionCommand`](/sdk/commands/#adjustprescription), [`MedicationStatementCommand`](/sdk/commands/#medicationstatement), [`PrescribeCommand`](/sdk/commands/#prescribe), and [`RefillCommand`](/sdk/commands/#refill). The value to be sent as the `fdb_code` is returned in the search payloads below as the `med_medication_id`.
####  `GET /fdb/grouped-medication/` — text and RxNorm search 
**Used by:** [Prescribe](/sdk/commands/#prescribe), [MedicationStatement](/sdk/commands/#medicationstatement), and [Refill](/sdk/commands/#refill) (`fdb_code`), and [Adjust Prescription](/sdk/commands/#adjustprescription) (`new_fdb_code`).
Search the medication catalog by full-text query or exact RxNorm RXCUI. Query parameters:
Parameter| Type| Description  
---|---|---  
`search`| string| Full-text search over the medication name, description, and synonyms.  
`rxnorm_rxcui`| string or int| Match a specific RxNorm RXCUI.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    # full-text search of the medication name, description, and synonyms
    response_json = ontologies_http.get_json(
        f"/fdb/grouped-medication/?{urlencode({'search': 'tylenol'})}"
    ).json()
    # search by a specific RxNorm RXCUI (same response shape)
    response_json = ontologies_http.get_json(
        f"/fdb/grouped-medication/?{urlencode({'rxnorm_rxcui': 313782})}"
    ).json()
    ```
The response contains a `results` list; each entry looks like:
    ```json
    {
      "results": [
        {
          "description_and_quantity": "Athenol 325 mg tablet",
          "med_medication_id": 436095,
          "search_rank": 0.082745634,

              "erx_ncpdp_script_quantity_qualifier_description": "Tablet"
            }
          ],
          "etc_path_id": [3645, 574, 578, 577],
          "etc_path_name": [

            "Analgesic, Anti-inflammatory or Antipyretic - Non-Opioid",
            "Analgesic or Antipyretic Non-Opioid and Combinations",
            "Analgesic or Antipyretic Non-Opioid"
          ],
          "rxnorm_rxcui": "313782"
        }
      ]
    }
    ```
Each result's `clinical_quantities` array supplies the values for a [`ClinicalQuantity`](/sdk/commands/#clinicalquantity) on prescribe commands — `representative_ndc`, `erx_ncpdp_script_quantity_qualifier_code` → `ncpdp_quantity_qualifier_code`, and `clinical_quantity_description` → `description`.
####  `GET /fdb/grouped-medication/{med_medication_id}/` — look up by FDB code 
Fetch one or more medications by FDB code. Pass a single `med_medication_id`, or a comma-separated list of ids, as the path segment.
Parameter| Type| Description  
---|---|---  
`med_medication_id` (path)| int, or comma-separated ints| One or more FDB medication ids.  
    ```python
    from canvas_sdk.utils.http import ontologies_http
    # single FDB code
    response_json = ontologies_http.get_json("/fdb/grouped-medication/123456/").json()
    # multiple FDB codes
    med_medication_ids = ["123456", "123457"]
    response_json = ontologies_http.get_json(
        f"/fdb/grouped-medication/{','.join(med_medication_ids)}/"
    ).json()
    ```
Returns the same full `results` shape as the text/RxNorm search above — each entry includes every field, including `clinical_quantities`:
    ```json
    {
      "results": [
        {

        }
      ]
    }
    ```
####  `GET /fdb/ndc-to-medication/{ndc}/` — look up by NDC 
Resolve a single NDC to its medication.
Parameter| Type| Description  
---|---|---  
`ndc` (path)| string| The NDC to resolve.

**Codes that resolve vs. free text.** A `med_medication_id` returned above resolves cleanly when passed as an `fdb_code` to a command. Some FDB entries — for example the `THSC …`-prefixed results the FHIR `/Medication` search can return — are not in this catalog and will render with a **blank medication name** if used. To record a historical or non-catalog medication as free text instead, pass a `Coding` with `system=CodeSystems.UNSTRUCTURED` (its `display` is used as-is) — see [MedicationStatement](/sdk/commands/#medicationstatement).
###  Searching for allergens 
Plugin authors can search the allergen catalog — the same catalog behind the chart's allergen autocomplete — by full-text or by RxNorm code.
####  `GET /fdb/allergy` — full-text search 
**Used by:** [Allergy](/sdk/commands/#allergy) (`allergy` — the allergen `concept_id` \+ `concept_type`).
Full-text search of the allergen catalog. Query parameters:
Parameter| Type| Description  
---|---|---  
`dam_allergen_concept_id_description__fts`| string| Full-text search over the allergen concept description.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    response_json = ontologies_http.get_json(
        f"/fdb/allergy?{urlencode({'dam_allergen_concept_id_description__fts': 'chocolate'})}"
    ).json()
    ```
The response contains a `results` list of allergen concepts:
    ```json
    {
      "results": [
        {
          "dam_allergen_concept_id": 19561,
          "dam_allergen_concept_id_description": "chocolate",
          "concept_type": "ingredient"
        }
      ]
    }
    ```
####  `GET /fdb/allergen` — RxNorm lookup 
Look up allergen concepts mapped to an external code. Query parameters:
Parameter| Type| Description  
---|---|---  
`code`| string| The external code to match, in `{system}\|{code}` form — e.g. `rxnorm\|217013`.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    response_json = ontologies_http.get_json(
        f"/fdb/allergen?{urlencode({'code': 'rxnorm|217013'})}"
    ).json()
    ```
Each result carries the FDB vocabulary type and id:
    ```json
    {
      "results": [
        {
          "evd_fdb_vocabulary_type_identifier": 104,
          "imk_fdb_vocabulary_no_identifier": 19561,
          "imk_fdb_vocabulary_description": "chocolate"
        }
      ]
    }
    ```
####  `GET /fdb/allergy/` — look up by concept id 
Resolve a specific allergen concept by id — for example, to confirm a stored allergy. Query parameters:
Parameter| Type| Description  
---|---|---  
`dam_allergen_concept_id`| int| The FDB allergen concept id.  
`dam_allergen_concept_id_type`| int| The allergen category — `1` (allergy group), `2` (medication), or `6` (ingredient).  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    response_json = ontologies_http.get_json(
        f"/fdb/allergy/?{urlencode({'dam_allergen_concept_id': 19561, 'dam_allergen_concept_id_type': 6})}"
    ).json()
    ```
Returns a `results` list containing the matching allergen concept (same fields as the full-text search above):
    ```json
    {
      "results": [
        {
          "dam_allergen_concept_id": 19561,
          "dam_allergen_concept_id_description": "chocolate",
          "concept_type": "ingredient"
        }
      ]
    }
    ```
####  Mapping results to `AllergyCommand`
To record one of these on a patient, pass the concept id and its type to [`AllergyCommand`](/sdk/commands/#allergy) as `concept_id` and `concept_type`. The catalog's allergen type maps to the command's category as follows:
Allergen type| `concept_type` (text search)| FDB vocabulary type (RxNorm search)| `AllergyCommand` category  
---|---|---|---  
Allergy group| `allergy group`| `110`| `1`  
Medication| `medication`| `1`| `2`  
Ingredient| `ingredient`| `104`| `6`  
For example, an allergy to chocolate is ingredient concept `19561` → category `6`.
###  Looking up clinical codes 
Beyond medications and allergens, the ontologies service resolves coded concepts that back several commands — ICD-10 conditions and CVX immunizations. (SNOMED concept searches are under Searching clinical concepts.)
####  `GET /icd/condition/` — ICD-10 conditions 
**Used by:** [Diagnose](/sdk/commands/#diagnose) (`icd10_code`), [Medical History](/sdk/commands/#medicalhistory) (`past_medical_history`), and the `diagnosis_codes` fields on [Refer](/sdk/commands/#refer), [Imaging Order](/sdk/commands/#imagingorder), and other diagnosis-code commands. _(Prescribe/Refill`icd10_codes` come from the patient's active conditions, not this search.)_
Search ICD-10 conditions by text, or resolve a specific code. This backs the condition/diagnosis autocompletes on commands such as [Diagnose](/sdk/commands/#diagnose), [Assess](/sdk/commands/#assess), and [Medical History](/sdk/commands/#medicalhistory). Query parameters:
Parameter| Type| Description  
---|---|---  
`search`| string| Full-text search over ICD-10 conditions.  
`icd10_code`| string| Resolve an exact ICD-10 code instead of searching. Dots optional (`E119` / `E11.9`).  
`date`| string| Optional. `YYYY-MM-DD`; resolves codes as of that date.  
`limit`| int| Optional. Maximum number of results.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    # full-text search
    response_json = ontologies_http.get_json(
        f"/icd/condition/?{urlencode({'search': 'type 2 diabetes'})}"
    ).json()
    # resolve a specific code
    response_json = ontologies_http.get_json(
        f"/icd/condition/?{urlencode({'icd10_code': 'E119'})}"
    ).json()
    ```
Returns a `results` list of matching conditions:
    ```json
    {
      "results": [
        {
          "icd10_code": "E11.9",
          "icd10_text": "Type 2 diabetes mellitus without complications",
          "snomed_concept_id": "44054006",
          "preferred_snomed_term": "Type 2 diabetes mellitus"
        }
      ]
    }
    ```
####  `GET /cpt/immunization/` — search immunizations 
**Used by:** [Immunization Statement](/sdk/commands/#immunizationstatement) (`cvx_code` / `cpt_code`).
Search vaccines by name or code. Query parameters:
Parameter| Type| Description  
---|---|---  
`name_or_code`| string| A vaccine code, or a text fragment of its name.  
`cvx_code`| string| Optional. Filter to a specific CVX code.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    response_json = ontologies_http.get_json(
        f"/cpt/immunization/?{urlencode({'name_or_code': 'influenza'})}"
    ).json()
    ```
The response contains a `results` list of matching vaccines:
    ```json
    {
      "results": [
        {
          "medium_name": "influenza, injectable, quadrivalent",
          "cpt_code": "90686",
          "cvx_code": "150",
          "cvx_description": "Influenza, injectable, quadrivalent"
        }
      ]
    }
    ```

    ```
###  Screening for drug–allergy interactions 
**Used by:** the [Prescribe](/sdk/commands/#prescribe) safety screening; also callable directly from a plugin (it is not tied to a command field).
> **Info:** Canvas runs this screening automatically on staged medication commands in the UI and displays the results to the provider. If you are using the SDK to automate the charting of these commands, that interactive screening may not surface — you may want to run this check yourself.
Canvas's drug–allergy screening — the same FDB-backed check the chart runs when a provider adds a medication — is available through `ontologies_http`.
`GET /fdb/medication-allergy/` takes a candidate medication and the patient's allergy list, both as JSON-encoded query parameters:
Parameter| Type| Description  
---|---|---  
`consideredMedication`| JSON string| The candidate drug's FDB codings as a flat list of `[code, "FDB"]` pairs, e.g. `[["217012", "FDB"]]`.  
`allergyList`| JSON string| The patient's allergies as `[code, category]` pairs, where `category` is the FDB allergen-concept type carried on the allergy record, e.g. `[["476", 1], ["1886", 6]]`.  
    ```python
    import json
    from urllib.parse import urlencode
    from canvas_sdk.commands.constants import CodeSystems
    from canvas_sdk.utils.http import ontologies_http
    from canvas_sdk.v1.data import Medication, Patient
    def fdb_codings(med: Medication) -> list[list[str]]:
        """The medication's FDB codings as [code, "FDB"] pairs."""
        return [
            [c.code, "FDB"]
            for c in med.codings.all()
            if c.code and c.system == CodeSystems.FDB
        ]
    def screen_medication_against_allergies(patient: Patient, considered_med: Medication) -> list[dict]:
        # Candidate medication: [[code, "FDB"], ...]
        considered_codings = fdb_codings(considered_med)
        # Patient's allergies: [[fdb_allergen_code, category], ...]
        allergy_ids = []
        for allergy in patient.allergy_intolerances.committed():
            fdb_coding = next(
                (c for c in allergy.codings.all() if c.code and c.system == CodeSystems.FDB),
                None,
            )
            if fdb_coding:
                allergy_ids.append([fdb_coding.code, allergy.category])
        if not considered_codings or not allergy_ids:
            return []  # nothing to screen → "all clear"
        params = urlencode(
            {
                "consideredMedication": json.dumps(considered_codings),
                "allergyList": json.dumps(allergy_ids),
            }
        )
        return ontologies_http.get_json(f"/fdb/medication-allergy/?{params}").json()
    ```
The response is a list of interaction objects — one per matched allergy, distinguishing a direct match from a cross-sensitive one (e.g. a penicillin allergy against a cephalosporin). An empty list `[]` means no interactions (all clear):
    ```json
    [
      {
        "drug": { "...": "full FDB medication payload" },
        "allergy_concept": {
          "dam_allergen_concept_id": 476,
          "dam_allergen_concept_id_type": 1,
          "dam_allergen_concept_id_description": "Penicillins"
        },
        "specific_ingredients": [],
        "cross_sensitive_ingredients": []
      }
    ]
    ```
###  Screening for drug–drug interactions 
**Used by:** the [Prescribe](/sdk/commands/#prescribe) safety screening; also callable directly from a plugin (it is not tied to a command field).
> **Info:** Canvas runs this screening automatically on staged medication commands in the UI and displays the results to the provider. If you are using the SDK to automate the charting of these commands, that interactive screening may not surface — you may want to run this check yourself.
The sibling `GET /fdb/medication-list-interaction/` endpoint checks a single candidate medication against the patient's existing medication list. It checks the candidate against each existing med — it does **not** check the existing meds against each other. Both inputs are JSON-encoded query parameters:
Parameter| Type| Description  
---|---|---  
`consideredMedication`| JSON string| The candidate drug's FDB codings as a flat list of `[code, "FDB"]` pairs, e.g. `[["217012", "FDB"]]`.  
`medicationList`| JSON string| The patient's existing meds as a list of per-drug coding lists — **one inner list per drug** , e.g. `[[["155744", "FDB"]], [["261266", "FDB"]]]`.  
> **Group`medicationList` one inner list per drug.** If you flatten it to one entry per coding row, a multi-coding drug can appear to interact with itself and produce false positives.
    ```python
    import json
    from urllib.parse import urlencode
    from canvas_sdk.commands.constants import CodeSystems
    from canvas_sdk.utils.http import ontologies_http
    from canvas_sdk.v1.data import Medication, Patient
    def fdb_codings(med: Medication) -> list[list[str]]:
        """The medication's FDB codings as [code, "FDB"] pairs."""
        return [
            [c.code, "FDB"]
            for c in med.codings.all()
            if c.code and c.system == CodeSystems.FDB
        ]
    def screen_drug_drug(patient: Patient, considered_med: Medication) -> list[dict]:
        considered_medication = fdb_codings(considered_med)
        # One inner list per existing drug; exclude the candidate itself.
        medication_list = [
            fdb_codings(med)
            for med in Medication.objects.for_patient(patient).active()
            if med.id != considered_med.id
        ]
        medication_list = [codings for codings in medication_list if codings]
        if not considered_medication or not medication_list:
            return []
        params = urlencode(
            {
                "consideredMedication": json.dumps(considered_medication),
                "medicationList": json.dumps(medication_list),
            }
        )
        return ontologies_http.get_json(
            f"/fdb/medication-list-interaction/?{params}"
        ).json()
    ```
The response is a list of interaction objects, one per interacting pair:
    ```json
    [
      {
        "existing_medication": 155744,
        "considered_medication": 217012,
        "existing_medication_description": "metformin 500 mg tablet",
        "severity": 2,
        "severity_text": "Severe Interaction: Action is required to reduce the risk of severe adverse interaction.",
        "monograph_text": ["Drug A / Drug B", "Clinical Effects: ...", "..."]
      }
    ]
    ```
`severity` uses FDB's DDIM scale — **lower number = more clinically significant** (the chart uses the same scale):
`severity`| Meaning  
---|---  
`1`| Contraindicated drug combination  
`2`| Severe interaction  
`3`| Moderate interaction  
`9`| Undetermined severity / alternative therapy  
**Screening several new medications at once:** checking each new med only against the patient's _current_ list misses interactions _between_ the new meds. Accumulate — after screening each new med, add it to the list you screen the next one against:
    ```python
    from canvas_sdk.v1.data import Medication, Patient
    patient = Patient.objects.get(id="e5f6a7b8-9c0d-4e1f-8a2b-3c4d5e6f7a8b")
    new_meds = list(Medication.objects.none())  # the medications you're about to add
    existing = list(Medication.objects.for_patient(patient).active())
    for new_med in new_meds:
        # screen new_med against `existing`, then:
        existing.append(new_med)  # so the next new med is checked against it too
    ```
##  Making requests to the Pharmacy service 
Plugin authors can make requests to our Pharmacy service using the `PharmacyHttp` client. This client provides a simplified interface for searching pharmacies and retrieving pharmacy details.
    ```python
    from canvas_sdk.utils.http import pharmacy_http
    ```
Unlike the general Http client, PharmacyHttp only provides two specific methods for pharmacy operations. Direct HTTP methods (get, post, put, patch) are not available.
###  Searching for pharmacies 
Search for pharmacies using full-text search, specific field filters, or location-based ordering.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`search_term`|  _string_| `false`| Full-text search across name, address, city, state, zip, and NCPDP ID.  
`latitude`|  _string_| `false`| Latitude coordinate for location-based ordering.  
`longitude`|  _string_| `false`| Longitude coordinate for location-based ordering.  
`id`|  _integer_| `false`| Exact pharmacy ID match.  
`ncpdp_id`|  _string_| `false`| Exact NCPDP ID match.  
`organization_name`|  _string_| `false`| Case-insensitive contains match on organization name.  
`specialty_type`|  _string_| `false`| Case-insensitive contains match on specialty type (e.g. "Retail").  
`state`|  _string_| `false`| Case-insensitive exact match on state (e.g. "NY").  
`zip_code_prefix`|  _string_| `false`| One or more comma-separated zip code prefixes (e.g. "100,902").  
**Example** :
    ```python
    from canvas_sdk.utils.http import pharmacy_http
    # Full-text search by name
    results = pharmacy_http.search_pharmacies("CVS")
    # Search with location-based ordering
    results = pharmacy_http.search_pharmacies(
        "pharmacy",
        latitude="40.7128",
        longitude="-74.0060"
    )
    # Filter by state and specialty type
    results = pharmacy_http.search_pharmacies(state="NY", specialty_type="Retail")
    # Filter by zip code prefixes
    results = pharmacy_http.search_pharmacies(zip_code_prefix="100,902")
    # Look up by exact NCPDP ID
    results = pharmacy_http.search_pharmacies(ncpdp_id="1234567")
    # The results list contains pharmacy objects like:
    # [
    #   {
    #     "id": 123456,
    #     "distance_miles": 0.8,
    #     "ncpdp_id": "1234567",
    #     "store_number": "#1234",
    #     "organization_name": "CVS Pharmacy #1234",
    #     "address_line_1": "123 MAIN ST",
    #     "address_line_2": "",
    #     "city": "New York",
    #     "state": "NY",
    #     "zip_code": "10001",
    #     "phone_primary": "2125551234",
    #     "fax": "2125555678",
    #     "latitude": 40.7128,
    #     "longitude": -74.0060,
    #     "npi": "1234567890",
    #     "specialty_type": "Retail",
    #     ...
    #   },
    #   ...
    # ]
    ```
###  Looking up a pharmacy by NCPDP ID 
Retrieve detailed information about a specific pharmacy using its NCPDP (National Council for Prescription Drug Programs) identifier.
**Parameters** :
Name| Type| Required| Description  
---|---|---|---  
`ncpdp_id`|  _string_| `true`| The NCPDP identifier of the pharmacy.  
**Example** :
    ```python
    from canvas_sdk.utils.http import pharmacy_http
    # Look up a specific pharmacy
    pharmacy = pharmacy_http.get_pharmacy_by_ncpdp_id("1234567")
    # The response contains detailed pharmacy information:
    # {
    #   "id": 123456,
    #   "ncpdp_id": "1234567",
    #   "store_number": "#1234",
    #   "organization_name": "Example Pharmacy #1234",
    #   "address_line_1": "123 MAIN ST",
    #   "address_line_2": "",
    #   "city": "New York",
    #   "state": "NY",
    #   "zip_code": "10001",
    #   "country": "US",
    #   "standardized_address_line_1": "123 Main St",
    #   "standardized_city": "New York",
    #   "standardized_state": "NY",
    #   "standardized_zip_code": "100010000",
    #   "phone_primary": "2125551234",
    #   "fax": "2125555678",
    #   "email": "",
    #   "active_start_time": "2020-01-01T00:00:00Z",
    #   "active_end_time": "2099-12-31T23:59:59Z",
    #   "service_level": "New~Refill~Change~Cancel~ControlledSubstance",
    #   "npi": "1234567890",
    #   "specialty_type": "Retail",
    #   "dea_number": "",
    #   "organization_type": "Pharmacy",
    #   "organization_id": 1234567,
    #   "latitude": 40.7128,
    #   "longitude": -74.0060,
    #   ...
    # }
    ```
###  Response fields 
Both methods return pharmacy objects with the following key fields:
  - `ncpdp_id`: Unique NCPDP identifier for the pharmacy
  - `organization_name`: Name of the pharmacy
  - `address_line_1`, `address_line_2`, `city`, `state`, `zip_code`: Physical address
  - `phone_primary`: Primary phone number
  - `fax`: Fax number
  - `npi`: National Provider Identifier
  - `specialty_type`: Type of pharmacy (e.g., "Retail", "Mail Order")
  - `service_level`: Services available (e.g., "New~Refill~Change~Cancel~ControlledSubstance")
  - `latitude`, `longitude`: Geographic coordinates
  - `distance_miles`: Distance from search location (only present in search results when location is provided)
##  Making requests to the Science service 
Plugin authors can make requests to our Science service using the `science_http` wrapper. The Science service backs autocomplete behavior in the Canvas note UI for imaging order codes (via parse templates) and for imaging centers and other clinical contacts.
    ```python
    from canvas_sdk.utils.http import science_http
    ```
Like `ontologies_http` and `pharmacy_http`, `science_http` is a JSON-only client. You can call `get_json()` and access the response with `json()` and `status_code`. Direct `get`/`post`/`put`/`patch` methods are not available.
###  Searching for imaging codes 
Use this to populate the `image_code` field of [`ImagingOrderCommand`](/sdk/commands/#imagingorder). `GET /parse-templates/imaging-reports/` accepts these query parameters:
Parameter| Type| Description  
---|---|---  
`query`| string| Full-text search over imaging report templates.  
`format`| string| Response format; pass `json`.  
`limit`| int| Maximum number of results to return.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import science_http
    params = {"query": "chest x-ray", "format": "json", "limit": 10}
    response_json = science_http.get_json(f"/parse-templates/imaging-reports/?{urlencode(params)}").json()
    ```
The response contains a `results` list of imaging report templates:
    ```json
    {
      "results": [
        {
          "code": "71046",
          "name": "X-ray of chest, 2 views",
          "code_system": "CPT"
        }
      ]
    }
    ```
Use the returned `code` on the command:
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.commands import ImagingOrderCommand
    from canvas_sdk.utils.http import science_http
    params = {"query": "chest x-ray", "format": "json", "limit": 10}
    response_json = science_http.get_json(f"/parse-templates/imaging-reports/?{urlencode(params)}").json()
    command = ImagingOrderCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        image_code=response_json["results"][0]["code"],
        diagnosis_codes=["R05"],
    )
    ```
###  Searching for contacts and service providers 
`GET /contacts/` searches the external contact directory — referring providers, specialists, imaging centers, and other service providers. Use it to populate a `ServiceProvider` on commands such as [Refer](/sdk/commands/#refer) and [Imaging Order](/sdk/commands/#imagingorder), to add external care-team members, or to look up a fax number for outbound faxing. Imaging centers are just contacts with a radiology job title — filter for them with `job_title__icontains=radiology`.
Query parameters (all optional; combine as needed):
Parameter| Type| Description  
---|---|---  
`search` (or `query`)| string| Full-text search over first/last name, practice name, job title, business address, phone, and fax.  
`job_title__icontains`| string| Filter by job-title substring — pass `radiology` to limit results to imaging centers.  
`business_postal_code__in`| string| Comma-separated ZIP codes to bias toward local results.  
`first_name__icontains`, `last_name__icontains`| string| Filter by contact name.  
`practice_name__icontains`| string| Filter by practice name.  
`business_fax__icontains`, `business_fax`| string| Filter by fax number (substring, or exact match).  
`format`| string| Response format; pass `json`.  
    ```python
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import science_http
    # General service-provider search (e.g. for a referral)
    params = {"search": "cardiology", "format": "json"}
    response_json = science_http.get_json(f"/contacts/?{urlencode(params)}").json()
    # Imaging centers: narrow to a radiology job title
    params = {
        "search": "advanced imaging",
        "job_title__icontains": "radiology",
        "format": "json",
        # Optional location filter:
        # "business_postal_code__in": "10001,10002",
    }
    response_json = science_http.get_json(f"/contacts/?{urlencode(params)}").json()
    ```
The response contains a `results` list of contact objects:
    ```json
    {
      "results": [
        {
          "firstName": "...",
          "lastName": "...",
          "practiceName": "Advanced Imaging Center",
          "specialty": "Radiology",
          "businessPhone": "2125551234",
          "businessFax": "2125555678",
          "businessAddress": "123 Main St, New York, NY 10001",
          "notes": "..."
        }
      ]
    }
    ```
Pass a selected contact as the `service_provider` on [Refer](/sdk/commands/#refer), [Imaging Order](/sdk/commands/#imagingorder), or other commands that accept a `ServiceProvider`; its `businessFax` and `businessAddress` also drive outbound faxing.

# Accessing Resource Attachment Files

Source: https://docs.canvasmedical.com/api/accessing-resource-attachment-files/

Several Canvas FHIR resources include a `url` attribute that points to an attachment file stored in S3. When you read or search these resources, the `url` value will be a `/files/` path on the Canvas FHIR server. Fetching that URL requires a **Bearer token** and returns a **redirect** to a pre-signed S3 URL that **expires after 10 minutes**.
There are two ways to retrieve the file, depending on whether you want the raw file content or the pre-signed URL itself.
##  Endpoints that return file URLs 
Resource| URL pattern  
---|---  
[Consent](/api/consent)| `GET /Consent/{id}/files/sourceAttachment`  
[DiagnosticReport](/api/diagnosticreport)| `GET /DiagnosticReport/{id}/files/presentedForm`  
[DocumentReference](/api/documentreference)| `GET /DocumentReference/{id}/files/content`  
[Media](/api/media)| `GET /Media/{id}/files/content`  
[Patient](/api/patient)| `GET /Patient/{id}/files/photo`  
[Practitioner](/api/practitioner)| `GET /Practitioner/{id}/files/signature`  
##  Option 1: Follow the redirect to get the file content 
The simplest approach is to let your HTTP client follow the redirect automatically. The pre-signed S3 URL contains its own authentication in the query parameters, so no additional headers are needed for the second request.
  - **curl**
        ```bash
        curl -L -o downloaded_file.pdf \
          -H "Authorization: Bearer $TOKEN" \
          "https://fumage-{instance}.canvasmedical.com/DocumentReference/abc123/files/content"
        ```
  - **python**
        ```python
        import requests
        base_url = "https://fumage-{instance}.canvasmedical.com"
        token = "your_bearer_token"
        file_url = f"{base_url}/DocumentReference/abc123/files/content"
        response = requests.get(
            file_url,
            headers={"Authorization": f"Bearer {token}"},
        )
        with open("downloaded_file.pdf", "wb") as f:
            f.write(response.content)
        ```
  - **javascript**
        ```javascript
        const response = await axios.get(url, {
          headers: { Authorization: `Bearer ${token}` },
          responseType: 'arraybuffer',
        });
        // response.data contains the raw file content
        writeFileSync('downloaded_file.pdf', Buffer.from(response.data));
        ```
##  Option 2: Capture the pre-signed URL without following the redirect 
If you need the pre-signed S3 URL itself — for example, to load it in an `<iframe>`, pass it to a frontend, or open it in a browser — you can configure your client to not follow redirects, and read the `Location` header in the response.
  - **curl**
        ```bash
        PRESIGNED_URL=$(curl -s -o /dev/null -w '%{redirect_url}' \
          -H "Authorization: Bearer $TOKEN" \
          "https://fumage-{instance}.canvasmedical.com/DocumentReference/abc123/files/content")
        echo "$PRESIGNED_URL"
        ```
  - **python**
        ```python
        import requests
        base_url = "https://fumage-{instance}.canvasmedical.com"
        token = "your_bearer_token"
        file_url = f"{base_url}/DocumentReference/abc123/files/content"
        response = requests.get(
            file_url,
            headers={"Authorization": f"Bearer {token}"},
            allow_redirects=False,
        )
        presigned_url = response.headers["Location"]
        # This URL works without auth and expires after 10 minutes
        ```
  - **javascript**
        ```javascript
        const response = await axios.get(url, {
          maxRedirects: 0,
          validateStatus: (status) => status === 307,
          headers: { Authorization: `Bearer ${token}` },
        });
        const presignedUrl = response.headers['location'];
        // This URL works without auth — use it in an iframe, open in browser, etc.
        ```
##  Note on HTTP client redirect behavior 
Per [RFC 9110](https://www.rfc-editor.org/rfc/rfc9110#section-15.4), compliant HTTP clients should strip the `Authorization` header when following a redirect to a different host. However, some HTTP clients do not do this, which can cause S3 to reject the request with a dual-auth error:
    ```xml
    <Error>
      <Code>InvalidArgument</Code>
      <Message>Only one auth mechanism allowed; only the X-Amz-Algorithm
      query parameter or the Authorization header should be specified,
      not both.</Message>
    </Error>
    ```
If you encounter this error, your client is forwarding the Bearer token to S3. Use **Option 2** above to handle the redirect manually, or configure your client to strip authorization headers on cross-origin redirects.

# Appointment

Source: https://docs.canvasmedical.com/api/appointment/

### 
A booking of a healthcare event among patient(s), practitioner(s), related person(s) and/or device(s) for a specific date/time. This may result in one or more Encounter(s).  
<https://hl7.org/fhir/R4/appointment.html>   
This may result in one or more [Encounters](/api/encounter).  
The appointment resource maps to both [patient appointments](https://canvas-medical.help.usepylon.com/articles/4617508394-appointment-management) as well as [other events](https://canvas-medical.help.usepylon.com/articles/4617508394-appointment-management#scheduling-other-events-30) in Canvas. Instructions for configuring event and note types can be found [here](https://canvas-medical.help.usepylon.com/articles/6785045644-appointment-event-note-types).
### Endpoints
post/Appointment get/Appointment/{id} put/Appointment/{id} get/Appointment
post
/Appointment
#### Appointment create
Create an **Appointment**  
It is recommended to utilize the [FHIR Slot Search](/api/slot#search) to find appointment times for a specific practitioner.  
**Prevent Double Booking** By default, Canvas does not prevent appointments from being created if there is already an existing appointment for that provider. However, Canvas has a config setting to disable double booking. If double booking is not allowed and the Appointment Create or Appointment Update request is trying to book an appointment for a given Provider that already has a scheduled appointment at that time, you will see a 422 error status with the following error message returned `This appointment time is no longer available.`
### Attributes
resourceType
string
The FHIR Resource name.
contained
array[json]
Contained, inline Resources. Used to store links for telehealth appointments.
This endpoint allows one custom video meeting link to be passed in that will be utilized on the UI over the default provider's meeting link if the appointment is a telemedicine. You can specify a telehealth meeting link by adding an element in the `SupportingInformation` attribute where the `SupportingInformation.reference` is `#appointment-meeting-endpoint-0` and matches the `contained[0].id` attribute of `appointment-meeting-endpoint-0`. See examples for help.
Click to view child attributes
resourceType
enum [ Endpoint ] required
id
string required
The `id` of the contained entry. This needs to be `appointment-meeting-endpoint-0` and the SupportingInformation.reference will be `#appointment-meeting-endpoint-0`.
address
string required
The technical base address for connecting to this endpoint.
identifier
array[json]
External Ids for this item.   
The identifier list defines additional identifiers that are able to be stored for an appointment.  
These identifiers will not be surfaced on the Patient's chart, but they may help you identify the patient in your system by associating your identifier with the resource's `id`.
Click to view child attributes
use
enum [ usual | official | temp | secondary | old ]
The purpose of this identifier. If this is omitted, it will default to `usual`.
system
string
The namespace for the identifier value.
value
string
The value that is unique
assigner
json
Text representing Organization that issued id. If ommitted it will default to the system of the identifier.
Click to view child attributes
display
string
period
json
Time period when id is/was valid for use.
Click to view child attributes
start
datetime
Starting time with inclusive boundary. If omitted this will default to `1970-01-01`.
end
datetime
End time with inclusive boundary, if not ongoing. If ommitted this will default to `2100-12-31`.
status
enum [ arrived | booked | cancelled | checked-in | fulfilled | noshow | pending | proposed ] required
The status of the appointment. The status `entered-in-error` may also be returned on read but is not accepted on create or update.   
This table shows the mappings of statuses/states an appointment is in within Canvas to the FHIR status attribute.   
FHIR Status| Canvas Status  
---|---  
proposed| unconfirmed  
pending| attempted  
booked| confirmed  
arrived| arrived  
checked-in| roomed  
fulfilled| exited  
noshow| noshowed  
cancelled| cancelled  
entered-in-error| deleted  
If any of the first 7 FHIR statuses are used, the appointment will appear on the schedule from the dropdown on the Appointment Card in the Schedule view with one of those statuses.   
An appointment can be created as `cancelled` for historical purposes, but it will not appear on the schedule view and will be a restorable note on the patient's timeline.   
The Create endpoint does NOT accept a status of `entered-in-error`.
appointmentType
json
The style of appointment or patient that has been booked in the slot (not service type). Canvas supports configurable [event and note types](https://canvas-medical.help.usepylon.com/articles/6785045644-appointment-event-note-types).
There are a few things to note with this attribute:   
1.If the `appointmentType` attribute is omitted from the body completely, the note type that has `Is default appointment type` will be used (usually Office Visit if unchanged)  
2.If the code / system pair does not exist, you will see a 422 error status with error message `Appointment Type does not exist with code: {code} and system: {system}`   
3.If the code / system pair passed is not marked as `Is Scheduleable` in Canvas, you will get a 422 error status with error message `Note type: {name} is not scheduleable`.
Click to view child attributes
coding
array[json]
The type of appointment
Click to view child attributes
system
string
The system of the appointment. On create and update, only `http://snomed.info/sct` and `INTERNAL` are accepted; other systems will be rejected.
**Value Options Supported:**
  - http://snomed.info/sct
  - INTERNAL
code
string
The code of the appointment.   
This needs to match a coding in the Event and Note Types Canvas Settings and be deemed as Is Scheduleable.
reasonCode
array[json]
Coded reason this appointment is scheduled.   
Canvas supports two ways to specify the reason for vist (RFV): [structured](/sdk/data-reason-for-visit/#reasonforvisitsettingcoding) and unstructured. Both the `coding` and `text` attributes are used for Structured RFVs, whereas unstructured RFVs only leverage the `text` attribute.
Canvas only accepts the first item in the reasonCode list.  
If you are taking advantage of our [structured reason for visit](/sdk/data-reason-for-visit/#reasonforvisitsettingcoding) feature, you can provide a `coding` that Canvas can use to look up the `code` value in configured in settings and display the structured RFV matching that code. If `Appointment.reasonCode[0].coding[0].code` is not a valid ReasonForVisitSettingCoding you will get the error "structured reason for visit with code {code} does not exist". You will also receive an error if the RFV code in Canvas' setting's page is not unique.   
The `text` attribute maps to the free text Reason For Visit command. If you are using the structured reason for visit feature, this text will display as the `comment` in the command. If you are not using the structured reason for visit feature, then only `Appointment.reasonCode[0].text` needs to be populated in your message and `coding` should be omitted.   
If this field is omitted (along with the deprecated `description` field), the RFV command in the appointment note will be defaulted to `No description given`.
Click to view child attributes
coding
array[json]
Code defined by a terminology system.
Click to view child attributes
code
string
The code of the reason for visit.
text
string
description
string
Shown on a subject line in a meeting request, or appointment list.  
This description attribute is useful for Scheduled Events in Canvas that do no have a corresponding timeline entry.  
For appointments associated with a patient timeline entry, we strongly suggest using the `reasonCode` field to map to the Reason For Visit command in a Canvas Note. However, this descrition will match the reasonCode.text attribute in a Read/Search
supportingInformation
array[json] required
Additional information to support the appointment. Currently, Canvas supports the ability to write 2 different types of references:   
  1. `Location`: A reference to a Location captures what Practice Location in Canvas the appointment will take place at.  
  2. `Meeting Link`: For appointments that are telehealth in Canvas, there can be a reference to an endpoint in this list. The reference attribute will need to match an `id` in the `Appointment.contained` attribute list, but will need to have a `#` in front of the reference string. See examples for help. For telehealth appointments where no meeting link reference is supplied, it will default to the practitioner's personal meeting room link as defined in Canvas Settings.
Click to view child attributes
reference
string required
The reference string of the supporting information.
If the entry is for a Location the format will be `"Location/9d3a079f-22c0-4918-96d7-72eb567563ec"`. You can retrieve this information for a [Location Search](/api/location#search).  
If the entry is for a virtual meeting link, the reference should be `#appointment-meeting-endpoint-0`.
type
string

status
enum [ arrived | booked | cancelled | checked-in | fulfilled | noshow | pending | proposed ]
The status of the appointment. The status `entered-in-error` may also be returned on read but is not accepted on create or update.   
This table shows the mappings of statuses/states an appointment is in within Canvas to the FHIR status attribute.   
FHIR Status| Canvas Status

reasonCode
array[json]
Coded reason this appointment is scheduled.   
Canvas supports two ways to specify the reason for vist (RFV): [structured](/sdk/data-reason-for-visit/#reasonforvisitsettingcoding) and unstructured. Both the `coding` and `text` attributes are used for Structured RFVs, whereas unstructured RFVs only leverage the `text` attribute.

text
string
description
string
Shown on a subject line in a meeting request, or appointment list.  
This description attribute is useful for Scheduled Events in Canvas that do no have a corresponding timeline entry.  
For appointments associated with a patient timeline entry, we strongly suggest using the `reasonCode` field to map to the Reason For Visit command in a Canvas Note. However, this descrition will match the reasonCode.text attribute in a Read/Search
supportingInformation
array[json]
Additional information to support the appointment. Currently, Canvas supports different types of references in this list:   
  1. `Location`: A reference to a Location captures what Practice Location in Canvas the appointment will take place at.  
  2. `Meeting Link`: For appointments that are telehealth in Canvas, there will be a reference to an endpoint in this list. The reference attribute will match an `id` in the `Appointment.contained` attribute list. That element will display the url address of the virtual meeting link.   
  3. `Appointment`: If an appointment has been rescheduled, this list could display an associated Appointment reference. If you see a display of `Previously Rescheduled Appointment`, it means that the appointment you are currently looking at was created after rescheduling the appointment in that Reference. If you see a display of `Rescheduled Replacement Appointment`, it means that the appointment you are currently looking at is now outdated by a new appointment. If you see a display of `Co-scheduled Appointment`, it means that the appointment you are currently looking at was scheduled with other additional associated appointments for which the appointment reference ID is noted.   
  4. `Encounter`: If there is any encounter associated with the appointment made in Canvas, the reference will appear in this list.

404 Not Found

put
/Appointment/{id}
#### Appointment update
This is almost identical to the [Appointment Create](/api/appointment/#create). You must include **all required fields** in the request body, even if only some fields are changing; omitting required fields will result in a validation error. Optional fields that are omitted will be ignored and left as they are currently set in the Canvas database.  
A FHIR Appointment update interaction behaves differently than a rescheduling workflow in the Canvas UI. FHIR updates will directly modify the Appointment referred to by the `id` rather than creating a new appointment.  
Canvas prevents updating the patient an appointment is already associated to. Best practice is to cancel the existing appointment and create a new appointment with the correct patient.
### Attributes
resourceType
string
The FHIR Resource name.
id
string required
The identifier of the appointment.
contained
array[json]
Contained, inline Resources. Used to store links for telehealth appointments.
This endpoint allows one custom video meeting link to be passed in that will be utilized on the UI over the default provider's meeting link if the appointment is a telemedicine. You can specify a telehealth meeting link by adding an element in the `SupportingInformation` attribute where the `SupportingInformation.reference` is `#appointment-meeting-endpoint-0` and matches the `contained[0].id` attribute of `appointment-meeting-endpoint-0`. See examples for help.
Click to view child attributes
resourceType
enum [ Endpoint ] required
id
string required
The `id` of the contained entry. This needs to be `appointment-meeting-endpoint-0` and the SupportingInformation.reference will be `#appointment-meeting-endpoint-0`.
address
string required
The technical base address for connecting to this endpoint.
identifier
array[json]
External Ids for this item.   
The identifier list defines additional identifiers that are able to be stored for an appointment.  
These identifiers will not be surfaced on the Patient's chart, but they may help you identify the patient in your system by associating your identifier with the resource's `id`.
To update an existing `identifier`, include the `id` in the `identifier[x].id` field returned from Read/Search.  
The `identifier` section sent in an update will entirely replace existing identifiers currently within the period.start and period.end dates.  
If an `identifier` already exists in the Canvas database and is not included in the Update message, it will be deleted if and only if the period.end date is in the future.

use
enum [ usual | official | temp | secondary | old ]

end
datetime
End time with inclusive boundary, if not ongoing. If ommitted this will default to `2100-12-31`.
status
enum [ arrived | booked | cancelled | checked-in | fulfilled | noshow | pending | proposed ] required
The status of the appointment. The status `entered-in-error` may also be returned on read but is not accepted on create or update.   
This table shows the mappings of statuses/states an appointment is in within Canvas to the FHIR status attribute.   
FHIR Status| Canvas Status  
---|---  
proposed| unconfirmed  
pending| attempted  
booked| confirmed  
arrived| arrived  
checked-in| roomed  
fulfilled| exited  
noshow| noshowed  
cancelled| cancelled  
entered-in-error| deleted  
If any of the first 7 FHIR statuses are used, the appointment will appear on the schedule from the dropdown on the Appointment Card in the Schedule view with one of those statuses.   
An appointment can be updated to `cancelled` and as a result it will disappear from the schedule view and/or will be a restorable note on the patient's timeline. Once an appointment is in a cancelled state, it should not be updated to a different status via FHIR, instead the note should be reverted directly in the Patient's chart before it can be updated via FHIR again.   
The Update endpoint does NOT accept a status of `entered-in-error`.
appointmentType
json
The style of appointment or patient that has been booked in the slot (not service type). Canvas supports configurable [event and note types](https://canvas-medical.help.usepylon.com/articles/6785045644-appointment-event-note-types).
There are a few things to note with this attribute:   
  1. If the `appointmentType` is an Other Event that does not require a patient, you must provide the `appointmentType` in the upload payload to pass validation.   
  2. For all appointments that require a patient, if the `appointmentType` attribute is omitted from the body completely on an update, the note type will stay as it already is in Canvas.  
  3. If the code / system pair does not exist, you will see a 422 error status with error message `Appointment Type does not exist with code: {code} and system: {system}`   
  4. If the code / system pair passed is not marked as `Is Scheduleable` in Canvas, you will get a 422 error status with error message `Note type: {name} is not scheduleable`.

code
string
The code of the appointment.   
This needs to match a coding in the Event and Note Types Canvas Settings and be deemed as Is Scheduleable.
reasonCode
array[json]
Coded reason this appointment is scheduled.   
Canvas supports two ways to specify the reason for vist (RFV): [structured](/sdk/data-reason-for-visit/#reasonforvisitsettingcoding) and unstructured. Both the `coding` and `text` attributes are used for Structured RFVs, whereas unstructured RFVs only leverage the `text` attribute.
On an update, if the reasonCode has changed from what is already saved in Canvas, it will create a new RFV command on that appointment. The old reason for visit will be marked as entered-in-error, and the text will no longer display. Below is an example of what an appointment's note will look like after changing the description multiple times. The originator and entered-in-error will be set to Canvas Bot, which can be seen if you click on the crossed off "Reason for Visit".  
![api-update-rfv](/assets/images/api-update-rfv.png)  
If this field is omitted (along with the deprecated `description` field), the RFV command in the appointment note will stay as it currently is.

supportingInformation
array[json] required
Additional information to support the appointment. Currently, Canvas supports the ability to write 2 different types of references:   
  1. `Location`: A reference to a Location captures what Practice Location in Canvas the appointment will take place at.  
  2. `Meeting Link`: For appointments that are telehealth in Canvas, there can be a reference to an endpoint in this list. The reference attribute will need to match an `id` in the `Appointment.contained` attribute list, but will need to have a `#` in front of the reference string. See examples for help. For telehealth appointments where no meeting link reference is supplied, it will default to the practitioner's personal meeting room link as defined in Canvas Settings.
Click to view child attributes
reference
string required
The reference string of the supporting information.
If the entry is for a Location the format will be `"Location/9d3a079f-22c0-4918-96d7-72eb567563ec"`. You can retrieve this information for a [Location Search](/api/location#search).  
If the entry is for a virtual meeting link, the reference should be `#appointment-meeting-endpoint-0`.
type

# Authentication - Best Practices

Source: https://docs.canvasmedical.com/api/authentication-best-practices/

##  Introduction 
The OAuth 2.0 authentication/authorization flow differs from the traditional username/password flow still heavily used in healthcare interoperability. To help users new to writing applications using OAuth, here are some best practices recommended by Canvas.
###  The Access Token: Don't lose it, reuse it 
####  Instead of this 
For some connections requiring a username and password, it may be necessary to use those credentials every time a message is sent to that system. In that type of flow, you might need to write something like:
    ```python
    import requests
    token = get_new_auth_token()
    patient = get_patient(token, patient_id)
    updated_patient_body = update_patient(patient, name="Frank")
    token = get_new_auth_token()
    update_patient(token, updated_patient_body)
    token = get_new_auth_token()
    schedule_appointment(token, patient=patient, type="telehealth")
    ...
    ```
Repeated, unnecessary calls to a token request function double the number of requests this script generates.
####  Do this 
Regardless of the authentication method used, a successful request includes `"expires_in": ` in the response body. The corresponding value will be an integer for the number of seconds until the token will be expired in Canvas. By reusing the token and eliminating redundant token requests, there is a **performance** gain from reducing the overall number of requests. The system is also more **secure** \- having fewer tokens reduces the overall surface area for illegitimate access
**General Guidelines:**
  - store the access token as securely as the client id and secret
  - depending on your use case, it may be best to store a token just for that session or to reuse it until it nears expiration
  - store the expiration datetime as well and check it before requesting a new token
  - use a refresh token if you provided in the authentication response for the authentication flow being used
There's any number of ways to do this in your language of choice. In Python, your code may look more like:
    ```python
    import os
    import requests
    from datetime import datetime, timedelta
    from urllib.parse import urlencode
    # we should get these from environment variables or a secure location at runtime, not in the code
    CLIENT_ID = os.getenv("CANVAS_API_CLIENT_ID")
    CLIENT_SECRET = os.getenv("CANVAS_API_CLIENT_SECRET")
    FUMAGE_BASE_URL = os.getenv("FUMAGE_BASE_URL")
    def get_new_auth_token():
        # Auth tokens are requested from the EMR instance, not the FHIR API.
        url = FUMAGE_BASE_URL.replace("fumage-", "")
        payload = urlencode(
            {
                "grant_type": "client_credentials",
                "client_id": f"{CLIENT_ID}",
                "client_secret": f"{CLIENT_SECRET}"
            }
        )

# CarePlan

Source: https://docs.canvasmedical.com/api/careplan/

### 
Describes the intention of how one or more practitioners intend to deliver care for a particular patient, group or community for a period of time, possibly limited to care for a specific condition or set of conditions.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-careplan.html>  
A CarePlan in Canvas translates to the [Integrated Care Plan PDF](https://canvas-medical.help.usepylon.com/articles/8547508751-administrative-menu-integrated-care-plan) you can print on the patient's chart. This endpoint will return either one or zero care plans for each patient. If no care plan was returned for a given patient, then that patient has never had a Goal command committed on their chart.

# CareTeam

Source: https://docs.canvasmedical.com/api/careteam/

### 
The Care Team includes all the people and organizations who plan to participate in the coordination and delivery of care for a patient.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-careteam.html>  
All patients in Canvas have a CareTeam by default. The identifier for the CareTeam resource for a patient is the same as the patient identifier.   
See our [article](https://help.canvasmedical.com/articles/5628604712-manage-care-teams) for information about setting up Care Teams and Care Team Roles in Canvas.
### Endpoints
get/CareTeam/{id} put/CareTeam/{id} get/CareTeam
get
/CareTeam/{id}
#### CareTeam read
Read a CareTeam resource.
### Path Parameters
id required
string
The unique identifier for the CareTeam   
The default behavior is to return all active care team participants for the patient. To return care team participants of a different status, add `.status` at the end of the ID (e.g `CareTeam/3e72c07b5aac4dc5929948f82c9afdfd.inactive`).
### Response Payload Attributes
resourceType
string
The FHIR Resource name.

#### CareTeam update
Update a CareTeam resource.  
The CareTeam update endpoint acts as an upsert, so there is no CareTeam `create` endpoint. Any participants included in the payload will be the patient's active care team participants. While any participants no longer included in the payload will be marked as `inactive`.   
**If-Unmodified-Since Header** :  
Due to a legacy design detail with the CareTeam implementation, there is a specific condition under which inclusion of this header will not produce expected results. In the case where all participants of a CareTeam are removed through the Canvas user interface (i.e. not through the FHIR API), the last modified date for the CareTeam will be equal to the last modified date of the patient record until another participant is added to the CareTeam.  
More information about the If-Unmodified-Since header can be found in the [Conditional Requests documentation](/api/conditional-requests/).

# Retrieving C-CDA via API

Source: https://docs.canvasmedical.com/api/ccda/

##  Software Requirements 
Software requirements for retrieving C-CDA via API calls can be found [here](/api/software-requirements)
##  Authentication 
If you have a Canvas Production instance, you will need to request a token and refresh it periodically. You can refer to our [Authentication Documentation](/api/customer-authentication) to get you set up.
##  Request and Parameters 
In order to generate a CCDA for a known patient key, you'll need to do a GET request to the endpoint `{YOUR_EHR_INSTANCE}/api/data-export/ccda/{patient_key}?document={document_type}`, where `document_type` can be either `continuity` or `referral`. You can check all parameters in the table below.
Parameter Name| Description| Requirement  
---|---|---  
document| Document type to be generated.  
Should be either `continuity` or `referral`| Mandatory  
start_date| Filter for the start date of the sections within the document.  
Format should be `YYYY-MM-DD`| Optional  
end_date| Filter for the end date of the sections within the document.  
Format should be `YYYY-MM-DD`| Optional  
generation_date| Overrides the generation date of the document.  
Format should be `YYYY-MM-DDTHH:mm:ss`, in UTC timezone| Optional  
##  Filtering 
`start_date` and `end_date` filter can be used to:
  - filter by a range of dates by inputing both parameters;
  - filter by a single date in the past by making `start_date` and `end_date` the same;
  - filter starting at a date in the past up until present time by only setting `start_date`;
  - filter from the beginning of time up to any date by only setting `end_date`;
##  Example and Response 
Here's a cURL example of a request for a continuity of care document, filtered for 2020-01-01 to 2020-12-31, and with a generation date of 2022-01-01, at 16:30 UTC:
    ```shell
    curl --request GET --header "Authorization: Bearer <token>" "<practice_subdomain>.canvasmedical.com/api/data-export/ccda/{PATIENT_KEY}?document=continuity&start_date=2024-01-01&end_date=2024-12-31&generation_date=2025-07-31T16:30:00"
    ```
A valid request will always return XML with the requested document as the response. If the `document` param is omitted, an empty XML will be returned.
##  Errors 
Canvas uses conventional HTTP response codes to indicate success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a request wasn't found, etc.). Codes in the 5xx range indicate an error with Canvas' server.
Error| Description  
---|---  
200 - OK| Everything worked as expected.  
403 - Forbidden| No valid Bearer token provided.  
404 - Not Found| The requested resource doesn't exist.  
500 - Server Error| Something went wrong on Canvas's end.

# Claim Operations

Source: https://docs.canvasmedical.com/api/claim-operations/

##  add-activity-log-item 
Add an activity log item to a Claim.  
This endpoint is a [FHIR operation](https://hl7.org/fhir/R4/operations.html), so it accepts a [Parameters](https://hl7.org/fhir/R4/parameters.html) resource in the request body. It will accept one and only one parameter, which must have the name **comment**. The comment that will be added is provided as a `valueString`. See the request example for more detail.
The bearer token included in requests send to this endpoint must have one of the following scopes:
  - `system/Claim.add-activity-log-item`
  - `user/Claim.add-activity-log-item`
  - **curl**
        ```shell
        curl --request POST \
             --url 'https://fumage-example.canvasmedical.com/Claim/<id>/$add-activity-log-item' \
             --header 'Authorization: Bearer <token>' \
             --header 'accept: application/json' \
             --header 'content-type: application/json' \
             --data '

                }
            ]
        }'
        ```
  - **python**
        ```python
        import requests
        url = "https://fumage-example.canvasmedical.com/Claim/<id>/$add-activity-log-item"
        headers = {
            "accept": "application/json",
            "Authorization": "Bearer <token>",
            "content-type": "application/json"
        }
        payload = {
            "resourceType": "Parameters",
            "parameter": [

# Communication

Source: https://docs.canvasmedical.com/api/communication/

### 
An occurrence of information being transmitted; e.g. a message that was sent to a responsible provider  
<https://hl7.org/fhir/R4/communication.html>  
The Communication resource maps to messages in Canvas between a patient and practitioner. Click [here](https://canvas-medical.help.usepylon.com/articles/6255444430-patient-message-inbox) to learn more.  
**Additional HTML formatting**  
With the release of Advanced Letter Templates, Messages are now saved in the database in HTML format. Customers using the Communication endpoint for their own patient applications will need to take this into account either by embedding the html directly using a library like Interweave or extracting the text. **Messages sent before this update (10/26/2022 @ 17:00 PST) will remain in plain text format.**  
### Endpoints
post/Communication get/Communication/{id} get/Communication
post
/Communication
#### Communication create
Messages created through this endpoint will be added to the patient's timeline and in the patient app based on the ingestion date into Canvas.
### Attributes
resourceType
string
The FHIR Resource name.
status
string required
The status of the transmission.
While status is a required attribute, all communication messages will be created with a `completed` status regardless of what is supplied in the payload.
**Value Options Supported:**

  - in-progress
  - preparation
  - unknown
sent
datetime
When sent  
**ISO 8601 format**

When received  
**ISO 8601 format**
If no `received` datetime is supplied when the recipient of the message is a Practitioner, the message will appear on the subject's timeline as unread, indicated by a blue circle on the message icon. The practitioner will have the ability to mark the communication message as read in the Canvas UI which will update this attribute.

# Condition

Source: https://docs.canvasmedical.com/api/condition/

### 
A clinical condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-condition-encounter-diagnosis.html>  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-condition-problems-health-concerns.html>
### Endpoints
post/Condition get/Condition/{id} put/Condition/{id} get/Condition
post
/Condition
#### Condition create
Create a Condition resource.  
This endpoint does not prevent duplicates in the record. **Canvas recommends performing a search prior to adding a new condition** to confirm whether the condition has already been created for the patient.  
If `clinicalStatus` is **active** , the Condition will be added as a `Diagnose` command. If it is not **active** , the Condition will be added as a `Past Medical History` command.  
If an `encounter` or a note ID in the `extension` is provided, the Condition will be added to the existing encounter (note). If it is not provided, a new data import note will be created.
### Attributes
resourceType
string
The FHIR Resource name.
extension
array[json]
Canvas supports a note identifier extension on this resource. The note identifier can be used with the [Canvas Note API](/api/note).
Canvas recommends sending the note identifier extension or the Encounter reference, but not both. If both are supplied, they must both refer to the same note. If neither is specified, it will insert into a Data Import note where the DOS is the current time of ingestion.

# Conditional Requests

Source: https://docs.canvasmedical.com/api/conditional-requests/

##  If-Unmodified-Since 
Endpoints that perform update operations support the conditional header [If-Unmodified-Since](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/If-Unmodified-Since).
If a request includes this header, then updates will be rejected if the stored resource has been modified since the date specified in the header, and a 412 Precondition Failed response will be returned.
The date should be in the format specified by [RFC 2616](https://www.rfc-editor.org/rfc/rfc2616).
    ```plaintext
    If-Unmodified-Since: Wed, 21 Oct 2015 07:28:00 GMT

For more information on consents in canvas, see this [article](https://help.canvasmedical.com/articles/8144965836-manging-patient-consents).
### Endpoints
post/Consent get/Consent/{id} get/Consent
post
/Consent
#### Consent create
Before creating a consent via the API, Patient Consent Codings **must** be [configured in Canvas](https://canvas-medical.help.usepylon.com/articles/8727821967-patient-consents).  
**Updating existing patient consent objects**  
A patient consent is uniquely distinguished by its patient and consent coding  
This Create endpoint also acts as an Update endpoint. If the patient already has an existing patient consent with the same consent coding, the endpoint updates that consent in place and the id returned in the response will not be changed.

status
enum [ active | cancelled ] required
The status of the Coverage.   
In Canvas, the status of `active` means it appears in the Patient's Profile page either under the main or other coverage sections, while a status of `cancelled` means it was removed and no longer appears on the page. An expired coverage will still show as `active`, so be sure to set/read the `period.end` attribute.
Currently there is no way to create a coverage that appears under the "Other Coverages" section on the Patient Profile. All coverages created with `active` will appear as the primary, secondary, tertiary, etc coverage depending on the order number. Coverages created with a `cancelled` status will not appear on the UI, but can still be read out.
type
json
Type of coverage, such as medical, workers compensation, self pay, etc.  
In order for this value to display on the Canvas UI, the coverage type needs to be configured for the specific payor via our insurer settings. To get to these settings, see this [Pylon article](https://help.canvasmedical.com/articles/5877696655-patient-coverages#managing-insurers-68).

# CoverageEligibilityRequest

Source: https://docs.canvasmedical.com/api/coverageeligibilityrequest/

### 
The CoverageEligibilityRequest provides patient and insurance coverage information to an insurer for them to respond, in the form of an CoverageEligibilityResponse, with information regarding whether the stated coverage is valid and in-force.  
<https://hl7.org/fhir/R4/coverageeligibilityrequest.html>
### Endpoints
post/CoverageEligibilityRequest
post
/CoverageEligibilityRequest
#### CoverageEligibilityRequest create
If Claim.MD is set up in your Canvas instance, a creation of a coverage CoverageEligibilityRequest will kick off a request to Claim.MD to fetch the eligibility information. Use the returned `id` in the response.headers['location'] attribute to perform a [CoverageEligibilityResponse Search](/api/coverageeligibilityresponse/#search) to see what response Claim.MD returned.
### Attributes
resourceType
string
The FHIR Resource name.
status
string required
Describes the state the request is in.
**Value Options Supported:**
  - active
purpose
array[string] required
What information is being requested.  
Supported values: only **["benefits"]** is valid
patient
json required
Canvas patient resource whom the CoverageEligibilityRequest is for.
Click to view child attributes
reference
string required
The reference string of the subject in the format of `"Patient/a39cafb9d1b445be95a2e2548e12a787"`.
type
string
Type the reference refers to (e.g. "Patient").
created
date required
Creation date, required by the FHIR specification, but unused by Canvas as it will be defaulted to the Canvas ingestion timestamp.  
Canvas recommends sending the current datetime in ISO 8601 format.
insurer
json required
Coverage issuer, required by the FHIR schema but unused by Canvas because we inherit the issuer directly from the Coverage resource provided.  
Canvas recommends setting `insurer` to `{}`.
insurance
array[json] required
Patient insurance information.  
Canvas requires a single coverage resource identifying the insurance to check eligibility against.
Click to view child attributes
coverage
json required
Insurance information.
Click to view child attributes
reference
string required
The reference string of the coverage in the format of `"Coverage/f7663d7b-13bd-4236-843e-086306aea125"`.
### Responses
201 Created
The server has successfully processed the request; the new resource has been created and is now ready for interaction.  
Canvas returns the created resource's id as a UUID within the `location` header and a `null` response body.
### Errors
400 Bad Request
The request was invalid or cannot be otherwise served. An accompanying error message will explain further.
401 Unauthorized
The request requires user authentication.
403 Forbidden
The request requires user authorization.
405 Method Not Allowed

### 
The CoverageEligibilityResponse resource provides eligibility and plan details from processing a CoverageEligibilityRequest resource. It combines key information from a payor as to whether a Coverage is in-force, and optionally the nature of the Policy benefit details as well as the ability for the insurer to indicate whether the insurance provides benefits for requested types of services or requires preauthorization and if so what supporting information may be required.

# Customer Authentication

Source: https://docs.canvasmedical.com/api/customer-authentication/

##  Introduction 
  - Canvas is an OAuth 2.0 authorization server.
  - This page contains information about how you can create third-party applications within your Canvas EHR instance and use those applications to access the FHIR API.
  - Canvas supports most OAuth flows, but this document will focus on two of the most used:
    - **Client Credentials** : Mostly used for Machine-to-Machine authentication (e.g., CLIs, Daemons).
    - **Authorization Code** : Usually used for web/native applications since it requires a user to log in to the system.
##  Registering a third-party application on Canvas 
  - Registering a third-party application is always the first step.
  - In order to do so, you'll need to:
    1. Go to `{YOUR_CANVAS_EHR_INSTANCE}/auth/applications/` where you'll see the following page: ![Authorization Page](/assets/images/ed67823-Screenshot_2021-10-26_at_16.22.31.png)
    2. Once you click the link on that page, you'll see the following: ![Application Registration](/assets/images/8b49344-Screenshot_2021-10-26_at_16.24.01.png)
    - You'll need to set a name for the app, set the `Client type` to `Confidential`, choose one of the `Authorization grant types`, and set the `Redirect URIs` if needed. Leave the `Algorithm` at `No OIDC support` for now.
    - Here's how it should look if you created a new "Test Application" with the `client-credentials` grant type: ![Application Example](/assets/images/6190a01-Screenshot_2021-10-26_at_16.26.59.png)
    - That's it. Take note of your `Client ID` and `Client Secret`, and proceed to the section related to the `Authorization Grant Type` you chose.
##  Client Credentials 
  - The Client Credentials flow assumes that everyone involved is capable of securely storing the `Client ID` and `Client Secret`.
  - In order to get a token, you just need to:
    ```shell
    curl --request POST '{YOUR_CANVAS_EHR_INSTANCE}/auth/token/' \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'grant_type=client_credentials' \
    --data-urlencode 'client_id={YOUR_CLIENT_ID}' \
    --data-urlencode 'client_secret={YOUR_CLIENT_SECRET}'
    ```
and you'll get back a JSON which will contain an `access_token` that'll be valid for 10 hours.
##  Authorization Code 
The Authorization Code flow ensures a user of the Canvas EHR explicitly approves the token request. It's typically used by web/mobile applications that act on behalf of a specific user (staff or patient).
The access token obtained through this flow carries the identity of the user who authorized it. This means:
  - **FHIR API calls** are scoped to that user's permissions.
  - **SimpleAPI plugin endpoints** receive the user as the [event actor](/sdk/events/#event-actor), allowing plugins to identify which user is making the request and enforce access controls.
###  Basic Steps 
  1. The application opens a browser to the Canvas authorization endpoint.
  2. The logged-in user sees the authorization prompt and approves the request.
  3. The user is redirected back to the `redirect_uri` with an authorization code in the query string.
  4. The application exchanges the authorization code for an access token and refresh token.
###  Step 1: Redirect the User to Authorize 
Open the following URL in the user's browser:
    ```text
    {YOUR_CANVAS_EHR_INSTANCE}/auth/authorize/?response_type=code&client_id={CLIENT_ID}&scope={SCOPES}&redirect_uri={REDIRECT_URI}&launch={LAUNCH_CONTEXT}
    ```
**Important notes:**
  - **`launch` parameter (required for staff users):** Staff users must include a `launch` parameter containing a base64-encoded JSON object with context. Without this parameter, the authorization will be denied with `error=access_denied`.
        ```bash
        # Encode a launch context with a patient id
        echo -n '{"patient":"PATIENT_KEY_HERE"}' | base64
        # Result: eyJwYXRpZW50IjoiUEFUSUVOVF9LRVlfSEVSRSJ9
        # Or with an empty patient (if no specific patient context is needed)
        echo -n '{"patient":""}' | base64
        # Result: eyJwYXRpZW50IjoiIn0=
        ```
  - **URL-encode special characters in scopes:** Scopes like `user/*.read` contain `/` which must be encoded as `%2F` in the URL. For example: `scope=user%2F*.read%20user%2F*.write`
  - **Authorization codes expire quickly:** The code returned in the redirect is valid for approximately 60 seconds. Exchange it for tokens immediately.
**Example authorize URL:**
    ```text
    {YOUR_CANVAS_EHR_INSTANCE}/auth/authorize/?response_type=code&client_id={CLIENT_ID}&scope=user%2F*.read%20user%2F*.write&redirect_uri=https://your-app.com/callback&launch=eyJwYXRpZW50IjoiIn0=
    ```
After the user clicks **Authorize** , they are redirected to your `redirect_uri` with a `code` parameter:
    ```text
    https://your-app.com/callback?code=AUTHORIZATION_CODE
    ```
###  Step 2: Exchange the Code for Tokens 
    ```shell
    curl --request POST '{YOUR_CANVAS_EHR_INSTANCE}/auth/token/' \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'grant_type=authorization_code' \
    --data-urlencode 'client_id={CLIENT_ID}' \
    --data-urlencode 'client_secret={CLIENT_SECRET}' \
    --data-urlencode 'redirect_uri={REDIRECT_URI}' \
    --data-urlencode 'code={CODE_FROM_PREVIOUS_STEP}'
    ```
**Response:**
    ```json
    {
      "access_token": "AN_ACCESS_TOKEN",
      "expires_in": 36000,
      "token_type": "Bearer",
      "scope": "user/*.read user/*.write",
      "refresh_token": "A_REFRESH_TOKEN",
      "patient": ""
    }
    ```
  - **`access_token`** : Valid for 10 hours (36000 seconds). Use this as a `Bearer` token in API requests.
  - **`refresh_token`** : Non-expiring but **single-use**. Each time you refresh, you receive a new refresh token — store it to maintain long-term access.
###  Step 3: Use the Token 
Use the access token as a Bearer token in the `Authorization` header:
    ```shell
    # FHIR API example
    curl --request GET '{FUMAGE_BASE_URL}/Patient' \
    --header 'Authorization: Bearer {ACCESS_TOKEN}'
    # SimpleAPI plugin endpoint example
    curl --request GET '{YOUR_CANVAS_EHR_INSTANCE}/plugin-io/api/{plugin_name}/{endpoint}' \
    --header 'Authorization: Bearer {ACCESS_TOKEN}'
    ```
When a SimpleAPI plugin receives a request with a Bearer token, Canvas validates the token, identifies the user, and sets them as the [event actor](/sdk/events/#event-actor). The plugin can then use `self.event.actor` to determine which user is making the request.
###  Step 4: Refresh the Token 
Access tokens expire after 10 hours. Use the refresh token to get a new access token without requiring the user to re-authorize:
    ```shell
    curl --request POST '{YOUR_CANVAS_EHR_INSTANCE}/auth/token/' \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'grant_type=refresh_token' \
    --data-urlencode 'client_id={CLIENT_ID}' \
    --data-urlencode 'client_secret={CLIENT_SECRET}' \
    --data-urlencode 'refresh_token={REFRESH_TOKEN}' \
    --data-urlencode 'scope={SCOPES}'
    ```
**Note:** The `scope` parameter must match the scopes from the original authorization (or be a subset). If omitted, Canvas will attempt to use the application's default allowed scopes, but this may fail with `invalid_scope` if the defaults don't match the original grant.
This returns a new `access_token` and a **new** `refresh_token`. The previous refresh token is consumed and cannot be reused. Store the new refresh token for the next refresh cycle.
###  Recommended Pattern for External Applications 
For applications that need to make API calls on behalf of specific Canvas users (e.g., a provider portal calling plugin endpoints):
  1. **One-time setup per user:** Each user authorizes the app via the browser flow. Store the refresh token per user in your backend.
  2. **Ongoing access:** Before making API calls, check if the access token is still valid. If expired, use the stored refresh token to get a new one.
  3. **Token storage:** Access tokens last 10 hours. Refresh tokens are non-expiring but single-use — always store the latest one returned from a refresh.
##  Patient Scoped Tokens 
Canvas supports patient scoped tokens. These are access tokens requested on behalf of a specific patient and have read/write access to that patient's records only.
To acquire a patient scoped token, you will need to include some parameters in the body of your token request:
  - A `client_id` and `client_secret` that your application will use to authenticate with Canvas.
  - The Canvas resource id for the `patient` the token will be scoped to
  - A `scope` parameter with space separated patient level scopes requested for the token.
    - Additional requested scopes should follow the pattern `patient/<ResourceName>.<read/write/*>`
      - `patient/Appointment.*`
      - `patient/Appointment.read patient/Appointment.write`
      - `patient/Patient.read`
      - `patient/Practitioner.read`
    - Canvas provides support for the wildcard character, but highly recommends only requesting the minimal scopes and access needed and using it as a convenience when both read and write are truly required for the application.
See Resources by context for the full list of resources a `patient/` scope can read and write.
###  Example curl request 
    ```bash
    curl --location --request POST \
          'https://<your_subdomain_here>.canvasmedical.com/auth/token/' \
          --header 'Content-Type: application/x-www-form-urlencoded' \
          --data-urlencode 'grant_type=client_credentials' \
          --data-urlencode 'client_id=<client_id_from_Canvas>' \
          --data-urlencode 'client_secret=<client_secret_from_Canvas>' \
          --data-urlencode 'patient=abc123' \
          --data-urlencode 'scope=patient/Patient.read patient/Appointment.* patient/Practitioner.read'
    ```
###  Expected Response Body 
    ```json
    {
      "access_token": "<the_access_token_to_use_in_your_request>",
      "expires_in": 36000,
      "token_type": "Bearer",
      "scope": "patient/Patient.read patient/Appointment.* patient/Practitioner.read",
      "smart_style_url": "https://canvas-storages.s3.us-west-2.amazonaws.com/fhir-static-resources/smart-style.json",
      "patient": "abc123",
      "need_patient_banner": true
    }
    ```
Using this access token in subsequent requests ensures that records referencing other patients cannot be retrieved through accidental or malicious misuse of the token. Canvas will also deny requests for any resource types which were not included in `scope` of the token request and requests for resource types which do not support patient-scoped tokens.
**Note:** A patient scoped token must include which patient scopes are being requested. Token requests that include the patient parameter but are missing scope or request invalid scopes will be rejected.
##  Scopes 
Scopes control which parts of the API the token can access.
  - **Client Credentials Flow:** Scopes are optional. If omitted, the token is issued with the OAuth application's configured allowed scopes.
  - **Authorization Code Flow:** Scopes are required and must be passed in the authorize URL.
Canvas implements [SMART on FHIR scopes](https://hl7.org/fhir/smart-app-launch/STU2/scopes-and-launch-context.html).
###  Scope syntax 
Most scopes have the form `<context>/<resource>.<permission>`:
  - **`<context>`** — `user/` (staff member; mirrors EHR permissions), `patient/` (limited to the launch-context patient), or `system/` (machine-to-machine, used with Client Credentials).
  - **`<resource>`** — a FHIR resource (e.g., `Patient`) or `*` for any supported resource.
  - **`<permission>`** — `read`, `write`, or `*` (v1 / legacy), or `c` (create), `r` (read), `u` (update), `s` (search) (v2 / granular). v2 letters can be combined, e.g., `Patient.crus`.
Separate multiple scopes with spaces, e.g., `user/Patient.read user/Observation.read`. URL-encode `/` as `%2F` and spaces as `%20`.
Common examples:
Scope| Description  
---|---  
`user/*.read`| Read access to all resources  
`user/*.write`| Write access to all resources  
`user/*.*`| Full access to all resources  
`user/Patient.read`| Read Patient resources only  
`system/*.read`| System-level read access to all resources (used for bulk-data export, e.g., `Group/{id}/$export`)  
###  Launch and OpenID scopes 
Scope| Description  
---|---  
`launch`| Allows external app launches  
`launch/patient`| Allows patient context  
`openid`| OpenID Connect scope  
`fhirUser`| Returns the authenticated user's FHIR identity  
`offline_access`| Requests a refresh token  
###  Resources by context 
Examples: `user/*.read`, `system/Patient.crus`, `patient/Appointment.write`.
**`user/`** — most clinical resources support `read`, `write`, `*`, and v2 `c r u s`. Read-only: `Coverage`, `MedicationDispense`, `Questionnaire`, `RelatedPerson`, `ServiceRequest`, `Specimen`. `Note` supports `read` and `write` only (no `*`). Resources: `*`, `AllergyIntolerance`, `CarePlan`, `CareTeam`, `Condition`, `Coverage`, `DetectedIssue`, `Device`, `DiagnosticReport`, `DocumentReference`, `Encounter`, `Goal`, `Immunization`, `Location`, `Medication`, `MedicationDispense`, `MedicationRequest`, `Note`, `Observation`, `Organization`, `Patient`, `Practitioner`, `PractitionerRole`, `Procedure`, `Provenance`, `Questionnaire`, `QuestionnaireResponse`, `RelatedPerson`, `ServiceRequest`, `Specimen`.
**`system/`** — same set as `user/` plus `Task` (full access). Read-only resources match `user/`. `system/Plugins.*` grants full access to plugin install/list/management endpoints.
**`patient/`** — restricted to the launch-context patient. Writable: `Appointment`, `Communication`, `Consent`, `Coverage`, `Media`, `MedicationStatement`, `Patient`, `PaymentNotice`, `QuestionnaireResponse`. All others read-only. Additional read-only resources beyond the user/system list: `Appointment`, `Communication`, `Consent`, `Media`, `MedicationStatement`, `PaymentNotice`, `Schedule`, `Slot`.
###  Operation scopes 
Some FHIR operations require a dedicated scope in addition to the resource scope. Available under both `user/` and `system/`:
Scope suffix| Operation  
---|---  
`Claim.add-activity-log-item`| Add an activity log entry to a Claim  
`DiagnosticReport.create-lab-report`| Create a lab report  
`Practitioner.send-reset-password-email`| Send a password-reset email to a practitioner

# Date Filtering

Source: https://docs.canvasmedical.com/api/date-filtering/

A few of the API Search endpoints support date search parameters. You have the ability to filter a Resources query result by a specific date or a date range. For more details, see https://hl7.org/fhir/search.html#prefix
We support the following date search modifiers:
  - `ge`   
Greater than or equal to the date.  
Example: `"?date=ge2021-01-01"``
  - `gt` Strictly greater than the date.   
Example: `"?date=gt2021-01-01"`
  - `le` Less than or equal to the date.   
Example: `"?date=le2021-01-01"`
  - `lt` Strictly less than the date.   
Example: `"?date=lt2021-01-01"`
  - `eq` Strictly equal to the date.   
Example: `"?date=eq2021-01-01"`  
You can supply multiple date search parameters to search in a range. For example if we want to find all the records within 2024-04-11 and 2024-04-20, we can pass `?date=ge2024-04-11&date=le2024-04-20`
The API endpoints that support date search parameters include:
  - [Appointment](/api/appointment/) (/Appointment) - Filter by appointment date
  - [Consent](/api/consent/) (/Consent) - Filter by consent date
  - [DetectedIssue](/api/detectedissue/) (/DetectedIssue) - Filter by identified date
  - [DiagnosticReport](/api/diagnosticreport/) (/DiagnosticReport) - Filter by report date
  - [DocumentReference](/api/documentreference/) (/DocumentReference) - Filter by document date
  - [Encounter](/api/encounter/) (/Encounter) - Filter by encounter date/period
  - [Observation](/api/observation/) (/Observation) - Filter by observation date/time
  - [QuestionnaireResponse](/api/questionnaireresponse/) (/QuestionnaireResponse) - Filter by authored date
  - [ServiceRequest](/api/servicerequest/) (/ServiceRequest) - Filter by authored date
  - [Task](/api/task/) (/Task) - Filter by date

# Third-Party Developer Access

Source: https://docs.canvasmedical.com/api/developer-access/

Canvas Medical is certified to ONC's [§170.315(g)(10)](/product-updates/rwt/) _Standardized API for Patient and Population Services_. This page describes how a third-party developer requests access to the FHIR API, the verification we perform, and the timelines we commit to under [45 CFR 170.404](https://www.ecfr.gov/current/title-45/section-170.404).
##  Two kinds of access 
The API supports two distinct access models. The authorization gate is different for each, and it is important to know which one your application needs.
###  Patient-directed access 
An individual patient authorizes your application to access **their own** health information. The patient authenticates and grants consent through the [SMART on FHIR](/api/customer-authentication/#authorization-code) authorization-code flow, and the resulting token is scoped to that patient (`patient/` context). The patient's authorization is the only approval required — access does not depend on separate sign-off from the patient's practice.
###  Population and bulk access 
A practice or organization using Canvas as its EHR authorizes access to data across its patient population, typically through the client-credentials flow (`system/` context) and bulk export. This access is authorized by the practice or organization that holds the data.
##  One Canvas instance per customer 
Each Canvas customer runs its own isolated instance, with its own base URL and its own authorization server. There is no single shared endpoint that spans customers. For patient-directed access, as part of verification we register and enable your application on every Canvas instance that has a patient portal enabled. Two things follow:
  - **Discover instances from the published directory.** The [Service Base URLs](/api/service-base-urls/) directory lists each customer's FHIR base URL in a machine-readable FHIR R4 Bundle, so your application can present the right practice to a user and route requests to the correct instance.
  - **Patients authorize on their own practice's instance.** For patient-directed access, send the patient to the authorization endpoint of the instance where they are a patient. They sign in with that practice's patient portal credentials and consent, and the resulting token is scoped to that single patient. Access to a given practice requires that the practice has its patient portal enabled and that the individual has a login there.
##  Requesting access 
Third-party developers do not need to be an existing Canvas customer to request access. To begin:
  1. Contact us at [developer-access@canvasmedical.com](mailto:developer-access@canvasmedical.com) with your organization name, a description of your application, the access model you need (patient-directed or population/bulk), and a technical point of contact.
  2. We complete an authenticity-verification review. This process is objective and applied uniformly to all API users, and we complete it within **ten business days** of receiving your request.
  3. Once verification is complete, we register and enable your application for production use within **five business days**.
We do not condition access on fees or royalties for the rights the API Condition of Certification protects, non-compete or exclusive-dealing terms, unrelated licenses, transfer of your intellectual property, Canvas-specific testing or certification, or reciprocal access to your application's data.
##  What we verify 
Verification confirms the authenticity of your organization and your application. It is limited to identity and does not evaluate the merits of your product. We apply the same criteria to every API user. You provide:
  - **Organization identity** — your registered legal business name and a verifiable business identifier, such as control of your organization's domain, a state business registration, or a D-U-N-S number.
  - **A domain-verified contact** — a named representative reachable at an email address on your organization's domain who can act on the organization's behalf.
  - **Application details** — the application name, a description of its intended use, the access model (patient-directed or population/bulk), and the redirect URIs or registered endpoints it will use.
  - **Attestations** — that the application has a published privacy policy and terms, that it will access data only as authorized by the patient (patient-directed access) or the organization (population/bulk access), and that you will comply with applicable law.
  - **Agreement to our[Terms of Use](/api/terms-of-use/).**
##  Sandbox access 
We provision a sandbox so your team can build and test before production enablement. Request sandbox credentials as part of step 1 above. Sandbox base URLs follow the pattern `https://fumage-<sandbox-name>.canvasmedical.com`; see the [Quickstart](/api/quickstart/) for making your first request.
##  Registering your application 
Once you have access to an instance (sandbox or production), register your application and obtain OAuth credentials by following [Customer Authentication](/api/customer-authentication/). That page documents the client-credentials and authorization-code flows and the available SMART scopes.
##  Fees 
There is no fee to register, verify, or enable a third-party application for access to the API.
##  Service base URLs 
Canvas publishes service base URLs for its customers. See [Service Base URLs](/api/service-base-urls/).
##  Terms of Use 
Use of the API is governed by our [Terms of Use](/api/terms-of-use/).

# Device

Source: https://docs.canvasmedical.com/api/device/

### 
A type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-implantable-device.html>  
For information about creating Device resources for a patient, see this [Zendesk article](https://canvas-medical.help.usepylon.com/articles/8311513697-implantable-devices). Devices are not currently used by the Canvas UI, but any devices that are created can be accessed with the Device read and search endpoints, In order to generate the type attribute, a device code must be created and linked to the device via the admin settings on Canvas.

# DiagnosticReport Operations

Source: https://docs.canvasmedical.com/api/diagnosticreport-operations/

##  create-lab-report 
Creates a lab report, lab tests, lab values, and a stored PDF in Canvas.
This endpoint is a [FHIR operation](https://hl7.org/fhir/R4/operations.html) and was developed as a convenience method in order to post all data associated with a lab report in a single request. In order to adhere to the FHIR standard, the request structure for creating lab reports is in the [Parameters](https://hl7.org/fhir/R4/parameters.html) format. This means that an array of named parameter resources makes up the body of the request.
In the example below, the first object in the parameter array is a named parameter called `labReport`. This references a `DiagnosticReport` resource. The `subject` attribute passed here must contain a valid patient reference and the `presentedForm` attribute must contain a base64-encoded string of the report PDF. Only one `labReport` parameter is allowed per payload.
The subsequent parameters in the array must be named `labTestCollection`. These represent the lab tests performed and associated result values. Each `labTestCollection` has a `part` array with `labTest` and `labValue` parameters. Only one `labTest` parameter is allowed per `labTestCollection`. Multiple `labValue` parameters are allowed per `labTestCollection`. Both resources must be represented as `Observation` resources.
To mark a lab value as abnormal, an optional `interpretation` attribute can be added to a `labValue` `Observation` resource. **Only abnormal interpretations (`"code": "A"`)** are currently supported, and the `interpretation` payload must match the exact structure shown in the example below (`text`, `coding[0].system`, `coding[0].code`, and `coding[0].display` are all required and must match).
For the values/units in each `labValue` object, a `valueQuantity`, `valueString`, or `valueCodeableConcept` can be supplied in the payload. For example:
    ```json
    {
      "valueQuantity": {
        "value": 0.7,
        "unit": "mg/dL",
        "system": "http://unitsofmeasure.org"
      }
    }
    ```
or
    ```json
    {
      "valueString": "Normal"
    }
    ```
or
    ```json
    {
      "valueCodeableConcept": {
        "coding": [
          {
            "system": "http://snomed.info/sct",
            "code": "260385009",
            "display": "Negative"
          }
        ]
      }
    }
    ```
If using `valueQuantity` and a comparator value is needed (i.e. `<1.0`), the comparator value can be passed in a `comparator` key like so:
    ```json
    {
      "valueQuantity": {
        "value": 1.0,
        "unit": "mg/dL",
        "system": "http://unitsofmeasure.org",
        "comparator": "<"
      }
    }
    ```
Supported `comparator` values are `<`, `<=`, `>=`, and `>`.
A `referenceRange` array may also be supplied on each `labValue` `Observation`. Only `referenceRange[0].text` is persisted in Canvas; `low` and `high` are accepted by the API but are not stored.
###  Validation requirements 
The following constraints are enforced when creating a lab report:
  - `labReport.presentedForm` must contain exactly one entry.
  - `labReport.presentedForm[0].contentType` must be `application/pdf`.
  - `labReport.presentedForm[0].data` is required and must contain a base64-encoded PDF.
  - `labReport.effectiveDateTime` must be a full ISO 8601 datetime (a date alone is not accepted).
  - Each `labTest` and `labValue` `Observation.code.coding` must contain exactly one entry, the `system` must be `http://loinc.org`, and `code` is required.
> **Warning:** While lab tests can be posted and are visible in the Canvas UI, they are not currently available to be read through the FHIR API. Only lab values can be read through the Observation resource.
The bearer token included in requests send to this endpoint must have one of the following scopes:
  - `system/DiagnosticReport.create-lab-report`
  - `user/DiagnosticReport.create-lab-report`

###  Response 
A successful request returns `201 Created` with a `Parameters` resource containing a `valueReference` to the newly created `DiagnosticReport`:
    ```json
    {
        "resourceType": "Parameters",
        "parameter": [
            {
                "name": "return",
                "valueReference": {
                    "reference": "DiagnosticReport/9b90621b-059f-4f6e-9ef5-58171098e424"
                }
            }
        ]
    }
    ```
Standard error responses (`400 Bad Request`, `401 Unauthorized`, `403 Forbidden`) follow the FHIR `OperationOutcome` shape described in [Errors](/api/errors).

# DocumentReference

Source: https://docs.canvasmedical.com/api/documentreference/

### 
A reference to a document of any kind for any purpose. Provides metadata about the document so that the document can be discovered and managed. The scope of a document is any seralized object with a mime-type, so includes formal patient centric documents (CDA), clinical notes, scanned paper, and non-patient specific documents like policy text.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-documentreference.html>  
A Document Reference can represent many different PDFs generated in Canvas:
  - A [Letter](https://canvas-medical.help.usepylon.com/articles/8181146406-letters) that has been faxed or printed from the patient's chart.
  - All documents uploaded via [Data Integration](https://help.canvasmedical.com/articles/7371085164-data-integration) and linked to a Patient. This includes Lab Reports, Imaging Reports, Referral Reports, Clinical, and Administrative Documents.
  - [POC Lab Commands](https://canvas-medical.help.usepylon.com/articles/7060961677-point-of-care-poc-tests) committed on the Patient's chart
  - [Clinical Notes](https://canvas-medical.help.usepylon.com/articles/1679996479-print-patient-chart) representing a PDF of each locked note. This also includes superseded versions on notes.
  - Any [Educational Material](https://canvas-medical.help.usepylon.com/articles/4966226408-educational-material-command) committed on a patient's chart.
  - Any [Invoices](https://help.canvasmedical.com/articles/9992348572-claim-management#invoicing-statements-128) generated for a patient.

### 
An interaction between a patient and healthcare provider(s) for the purpose of providing healthcare service(s) or assessing the health status of a patient.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-encounter.html>  
**Encounter creation in Canvas**  
An encounter is associated with some of our notes in Canvas. For our default base notes, an encounter will be created with these note types:   
\- Lab visit   
\- Phone visit   
\- Telehealth visit   
\- Office visit   
\- Home Visit   
\- In-patient Visit   
With our [Configurable Note Types Feature](https://help.canvasmedical.com/articles/6785045644-appointment-event-note-types) all custom note types will be associated with an encounter by default.

reasonReference

Reason the encounter takes place (reference).   
In Canvas this represents the conditions that were **created** during the encounter, via the Diagnose command or another command that creates a condition.   
This list does **not** include conditions that were only assessed during the encounter. An Assess command records an assessment against a condition that already exists in the chart, and it does not change which encounter that condition belongs to, so an encounter whose only condition activity was an Assess returns an empty `reasonReference`. To retrieve the conditions assessed during an encounter, use the [Assessment](/sdk/data-assessment) model in the Canvas SDK, which links each assessment to both the note it was documented on and the condition it assessed. For the diagnoses associated with a billed service, use `diagnosis` and `item.diagnosisSequence` on the [Claim](/api/claim) resource.

# Errors

Source: https://docs.canvasmedical.com/api/errors/

Canvas uses conventional HTTP response codes to indicate success or failure of an API request. In general: Codes in the `2xx` range indicate success. Codes in the `4xx` range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a request wasn't found, etc.). Codes in the `5xx` range indicate an error with Canvas' server.
All `4xx` errors that could be handled programmatically (e.g., resource not found) include an [OperationOutcome](https://www.hl7.org/fhir/operationoutcome.html) that explains the error reported
Error Code| Description  
---|---  
200 - OK| Everything worked as expected.  
400 - Bad Request| The request was malformed or rejected by validation.  
401 - Unauthorized| No valid Bearer token provided.  
403 - Forbidden| Token bearer is forbidden from performing the operation.  
404 - Not Found| The requested resource doesn't exist.  
412 - Precondition Failed| A conditional request failed because the resource has been modified since the precondition was specified.  
422 - Unprocessable Entity| The request was syntactically correct but failed due to request semantics, database state, or a business rule.  
5XX - Server Error| Something went wrong on Canvas's end.

# Group

Source: https://docs.canvasmedical.com/api/group/

### 
Represents a defined collection of entities that may be discussed or acted upon collectively but which are not expected to act collectively, and are not formally or legally recognized; i.e. a collection of entities that isn't an Organization.  
<https://hl7.org/fhir/R4/group.html>  
In Canvas Teams and Patient Groups are mapped to the FHIR Group resource.   
See this [Pylon article](https://canvas-medical.help.usepylon.com/articles/5123845479-teams) for information about creating teams in Canvas.  
See this [Pylon article](https://help.canvasmedical.com/articles/8319995182-patient-groups) for information about patient groups in Canvas.
### Endpoints
post/Group get/Group/{id} put/Group/{id} get/Group
post
/Group
#### Group create
Create a Group resource.  
**Note:** The Canvas implementation of Group create/update assigns responsibilities to practitioner Groups using the `characteristic` attribute, rather than using the `characteristic` attribute to establish membership.
### Attributes
resourceType
string
The FHIR Resource name.
type
string required
Identifies the broad classification of the kind of resources the group includes.   
A group with type `person` refers to a Patient Group in canvas, while a group of type `practitioner` refers to a Team in Canvas.
**Value Options Supported:**
  - person
  - practitioner
actual
boolean required
If true, indicates that the resource refers to a specific group of real individuals. If false, the group defines a set of intended individuals.   
While this is a required field in FHIR, Canvas assumes all groups are made up of real individuals, so this will be assumed True for all interactions.
name
string required
Label for Group.
characteristic
array[json]
Identifies traits whose presence or absence is shared by members of the group  
The `text` attribute on the `valueCodeableConcept` for each `characteristic` represents responsibilities held by the Group (in Canvas a Team). Responsibilities may not be shared by more than one team.
If a group of practitioners is created/updated with a responsibility that another group is assigned, the endpoint will return an error dictating the responsibilities have already been assigned.

# Immunization

Source: https://docs.canvasmedical.com/api/immunization/

### 
Describes the event of a patient being administered a vaccine or a record of an immunization as reported by a patient, a clinician or another party.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-immunization.html>  
In Canvas, Immunization records are recorded using either the [Immunization Statement Commmand](https://canvas-medical.help.usepylon.com/articles/1379672479-command-immunization-statement) or the [Immunize Command](https://canvas-medical.help.usepylon.com/articles/4155771468-command-immunize).
### Endpoints
post/Immunization get/Immunization/{id} put/Immunization/{id} get/Immunization
post
/Immunization
#### Immunization create
Immunization records created through this endpoint will be stored in an Immunization Statement command on the patient's chart. There currently is no support to create an Immunize command with this endpoint.
### Attributes
resourceType
string
The FHIR Resource name.
extension
array[json]
Canvas supports a note identifier extension on this resource. The note identifier can be used with the [Canvas Note API](/api/note).
Canvas recommends sending the note identifier extension or the Encounter reference, but not both. If both are supplied, they must both refer to the same note. If neither is specified, it will insert into a Data Import note where the DOS is the current time of ingestion.

# Letter

Source: https://docs.canvasmedical.com/api/letter/

This API allows customers to create letters. The effect of creating a letter is the same as creating a letter in the user interface. Content can be added using HTML & CSS. Placeholders created in Canvas will not be respected.
##  Authentication 
The Letter API uses the existing Canvas OAuth authentication flow, so you can simply post to the existing auth token endpoint /auth/token/
This endpoint was built as an addition to the Note API and uses the user/Note.write scope. This scope will not be in OAuth applications that were created prior to the release of the Note API. To get access:
  - Create a new [OAuth application](/api/customer-authentication)
  - Ask Canvas to add the new scopes to an existing OAuth application
![description](/assets/images/allowed-scopes.png)
    ```python
    import requests
    url = "https://<your-instance>.canvasmedical.com/auth/token/"
    payload = 'grant_type=client_credentials&client_id=canvas&client_secret=canvas'
    headers = {
      'Content-Type': 'application/x-www-form-urlencoded'
    }
    response = requests.request("POST", url, headers=headers, data=payload)
    print(response.text)
    ```
Then use your token in the request headers as you do with the FHIR API:
![description](/assets/images/note-api-token.png)
##  Create 
To create a Note resource, POST to `https://<your-instance>.canvasmedical.com/core/api/letter/v1/Letter` using the supported attributes below. Letters will be staged on the patient's chart to then be faxed or printed. Further edits can be made in the UI as needed.
###  Attributes 
**`patientKey` (req)** text  
The unique key of the Patient for which this letter is written.
* * *
**`providerKey` (req)** text  
The unique key of the Provider staff who is responsible for the letter.
* * *
**`practiceLocationKey` (req)** text  
The unique key of the PracticeLocation for which this letter is written.
* * *
**`content`**  
The contents of the letter. Supports HTML & CSS. **Placeholders created in Canvas will NOT be respected.**
###  Example 
    ```python
    import requests
    import json
    url = "https://<your-instance>.canvasmedical.com/core/api/letter/v1/Letter"
    payload = json.dumps({
      "patientKey": "8d84776879de49518a4bc3bb81d96dd4",
      "providerKey": "5eede137ecfe4124b8b773040e33be14",
      "practiceLocationKey": "c67e0c59-d4d2-428c-bc13-b6e85d181ad0",
      "content": "<p>To Whom It May Concern,</p><p>Letty Letters is a patient of mine at PRACTICE NAME. Due to a current medical condition, the patient is unable to fulfill the requirements for jury duty.</p><p>Thanks,</p></div><div class=\"signature\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/b/be/Zhu_Zhengting_signature.jpg/1280px-Zhu_Zhengting_signature.jpg\" alt=\"Signature\" width=\"200\"></div></div></html>"
    })
    headers = {
      'Authorization': 'Bearer HqFtbSnBNX4S65VhRrg8sRxO6XcSFp',
      'Content-Type': 'application/json'
    }
    response = requests.request("POST", url, headers=headers, data=payload)
    print(response.text)
    ```

# Media

Source: https://docs.canvasmedical.com/api/media/

### 
A photo, video, or audio recording acquired or used in healthcare.  
<https://hl7.org/fhir/R4/media.html>  
FHIR Media maps to a [Visual Exam Finding Command](https://canvas-medical.help.usepylon.com/articles/4119751144-command-visual-exam-finding) in Canvas.
### Endpoints

### Attributes
resourceType
string

extension
array[json]
Canvas supports a note identifier extension on this resource. The note identifier can be used with the [Canvas Note API](/api/note).
Canvas recommends sending the note identifier extension or the Encounter reference, but not both. If both are supplied, they must both refer to the same note. If neither is specified, it will insert into a Data Import note where the DOS is the current time of ingestion.

# Medication

Source: https://docs.canvasmedical.com/api/medication/

### 
This resource is primarily used for the identification and definition of a medication for the purposes of prescribing, dispensing, and administering a medication as well as for making statements about medication use.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-medication.html>  
Best practice is to utilize this endpoint to find codings to feed the [Medication Statement Create/Update](/api/medicationstatement/#create). These medications come directly from our integration with FDB.
### Endpoints
get/Medication/{id} get/Medication
get
/Medication/{id}
#### Medication read
Read a Medication resource.
### Path Parameters
id required
string
The unique identifier for the Medication   
### Response Payload Attributes
resourceType
string
The FHIR Resource name.
id
string
The identifier of the Medication.
text
json
Text summary of the Medication, for human interpretation.

#### Medication search
Search for Medication resources.
### Query Parameters
**A Medication Search requires either a code or _text search parameter to perform.**
_text
string
Performs a case insensitive partial search on the narrative of the Medication.
code
System url and code that identifies the medication formatted like   
`system_url|code`.  
Currently a search for an RxNorm code will return both branded and generic medications associated with the RxNorm code regardless of whether the RxNorm code is branded or generic.  
For example, a search for the RxNorm code that represents the branded version of metformin will return a search bundle that contains at least two Medication resources – one for the branded version and one for the generic version. The branded and generic Medication resources in the search bundle can be differentiated by the presence or absence of the RxNorm code for the branded version in the list of codings.
**Search Values Supported:**
  - http://www.nlm.nih.gov/research/umls/rxnorm|code
### Response Payload Attributes
resourceType
string
The FHIR Resource name.
type
string
This element and value designate that the bundle is a search response. Search result bundles will always have the Bundle.type of searchset .

# MedicationRequest

Source: https://docs.canvasmedical.com/api/medicationrequest/

### 
An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-medicationrequest.html>  
FHIR MedicationRequest maps to the [Prescribe, Refill, Adjust Prescription, Deny Refill, Approve Refill](https://canvas-medical.help.usepylon.com/articles/5128727084-managing-medication-commands) commands in Canvas.

# MedicationStatement

Source: https://docs.canvasmedical.com/api/medicationstatement/

### 
A record of a medication that is being consumed by a patient. A MedicationStatement may indicate that the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains.  
<https://hl7.org/fhir/R4/medicationstatement.html>  
MedicationStatement resources can be created in two ways in the Canvas UI:
  - [Prescribe commands](https://canvas-medical.help.usepylon.com/articles/5128727084-managing-medication-commands#prescribe-command-7) create [MedicationRequest](/api/medicationrequest/) resources, but these `Prescribe` commands are also represented as MedicationStatement resources. MedicationStatement resources that were created with a `Prescribe` command will contain a reference to the related MedicationRequest resource in the `derivedFrom` attribute.
  - MedicationStatement resources can also be created with the [Medication Statement command](https://canvas-medical.help.usepylon.com/articles/5128727084-managing-medication-commands#medication-statement-command-1)
### Endpoints
post/MedicationStatement get/MedicationStatement/{id} put/MedicationStatement/{id} get/MedicationStatement
post
/MedicationStatement
#### MedicationStatement create
Create a MedicationStatement resource.  
If `context` or `extension` is provided, the MedicationStatement will be added to the existing encounter (note). If it is not provided, a new data import note will be created.  
Create requests support either `medicationReference` or `medicationCodeableConcept` in the request body; Canvas recommends using `medicationReference`. Medication identifiers for `medicationReference` can be obtained from the [Medication search endpoint](/api/medication/#search).
### Attributes
extension
array[json]
Canvas supports a note identifier extension on this resource. The note identifier can be used with the [Canvas Note API](/api/note).
Canvas recommends sending the note identifier extension or the Encounter reference, but not both. If both are supplied, they must both refer to the same note. If neither is specified, it will insert into a Data Import note where the DOS is the current time of ingestion.

# Note

Source: https://docs.canvasmedical.com/api/note/

This API allows customers to create and update notes. The effect of creating a note is the same as creating a note in the user interface (for example for a note with category "encounter" will create an encounter, a note that is billable will create a claim). Not all note attributes can be modified on update. For example, note type cannot be changed after note creation.
##  Authentication 
The Note API uses the existing OAuth authentication flow from the FHIR API, so you can simply post to the existing auth token endpoint /auth/token/
New scopes are introduced: user/Note.read and user/Note.write. These scopes will not be in OAuth applications that were created prior to the release of this feature. Therefore to get access, you have two options:
  - Create a new [OAuth application](/api/customer-authentication)
  - Ask Canvas to add the new scopes to an existing OAuth application
![description](/assets/images/allowed-scopes.png)
    ```python
    import requests
    url = "https://<your-instance>.canvasmedical.com/auth/token/"
    payload = 'grant_type=client_credentials&client_id=canvas&client_secret=canvas'
    headers = {
      'Content-Type': 'application/x-www-form-urlencoded'
    }
    response = requests.request("POST", url, headers=headers, data=payload)
    print(response.text)
    ```
Then use your token in the request headers as you do with the FHIR API:

The following USCDI data elements are retrievable from this endpoint:  
  - Laboratory Tests
  - Laboratory Values/Results
  - Smoking Status
Here are some Canvas specific workflows where observations will be created:
  1. Documenting Vitals via our [Vital Command](https://canvas-medical.help.usepylon.com/articles/9426091672-command-vitals) (category coding will be `vital-signs`)  
  2. Submitting a Questionnaire, Review Of System (ROS), Structured Assessment (SA), or a Physical Exam will result in an observation for each question answered if the question's code system is LOINC or SNOMED (category coding will be `social-history`).   
  3. There is a specific Physical Exam to capture Pediatric Vitals. Upon submission of the Exam, associated observations for Body Length, Head Circumference, and Head Occipital-Frontal Circumference Percentile (category coding will be `vital-signs`) will be created along with the observations for the answers of the exam (category coding will be `social-history`). Please contact Customer Support for help loading this Exam into your instance if you want to utilize it.   
  4. Once weight and either height or pediatric body length is entered on a patients chart, the vital observations of BMI for Age Percentile (for patients 2 years or older) and Weight-for-Length Percentile will be calculated (category coding will be `vital-signs`).
  5. Submitting a Questionnaire that has custom scoring defined will result in an observation containing the scored value (category coding will be `survey`).   
  6. When a lab report is created in Canvas through [DI](https://canvas-medical.help.usepylon.com/articles/1652834476-labs-lab-reports), API, integration with HG, or [POC Lab Test Command](https://canvas-medical.help.usepylon.com/articles/7060961677-point-of-care-poc-tests), there will be resulting Observations made (category coding will be `laboratory`).

### Endpoints
post/Observation get/Observation/{id} get/Observation
post
/Observation
#### Observation create
Although the observation endpoint houses many different Canvas models, currently, **only vital signs and panels can be created through this endpoint**.  
**Vital signs and Vital Sign Panels**  
See this [helpful guide](/guides/submit-vitals-via-fhir/) to walk you through creating a vital panel via FHIR.  
  - Vital sign panels and vital signs are both observations.  
    - Vital sign panels are the parent that "contain" the vital sign observations. The `hasMembers` attribute contains references to the child observations  
    - Each vital sign that is part of the panel links back to the parent Observation via the `derivedFrom` attribute.  
    - If a `derivedFrom` value is not included for a vital sign observation, then a new vital sign panel observation is created and will autofill the `derivedFrom` attribute field.  
  - Vital signs and their parent panel feed into our [Vitals command](https://canvas-medical.help.usepylon.com/articles/9426091672-command-vitals).  
**Note types**  
Most our FHIR endpoints insert commands into a Data Import Note type on the patient's timeline. With the release of [configurable note types](https://help.canvasmedical.com/articles/6785045644-appointment-event-note-types), if you create a new Note Type in Settings with **system = Canvas** and **code = VitalsImport** , then the Observation Create endpoint will always import into that note type instead.  
**Supported vital sign codes used in create**
vital sign| LOINC code| default unit| additional accepted units  
---|---|---|---  
vital sign panel| 85353-1|  |   
blood pressure| 85354-9| mmHg|   
weight| 29463-7| oz| lb, kg  
height| 8302-2| in| cm  
pulse rate| 8867-4| bpm|   
body temperature| 8310-5| °F|   
oxygen saturation (arterial)*| 2708-6| %|   
oxygen saturation*| 59408-5| %|   
respiration rate| 9279-1| bpm|   
waist circumference| 56086-2| cm| in  
note| 80339-5|  |   
pulse rhythm| 8884-9|  |   
*If an oxygen saturation vital sign is created, an oxygen saturation (arterial) vital sign code is also automatically generated.  
A vital sign code that is not listed in the table above is rejected with a 405 and the message `Sign is not supported by Canvas`. In particular, **supplemental oxygen (88658-0) cannot be created through this endpoint** — it can only be captured through the Vitals command in Canvas. Supplemental oxygen observations are still returned by read and search, where the value appears as a `valueCodeableConcept`.

hasMember
array[json]
Related Observation reference(s) that belongs to the Observation group/panel.  
Only need to supply this attribute in a Vital Sign Panel to specify specific child observations that are a part of the panel. In Canvas these will form the Vitals Command. This observation IDs can be found using the [Observation Search](/api/observation/#search).   
If a new vital sign panel is created and links pre-existing vital signs via the `hasMember` attribute, those linked observations will update their `derivedFrom` attribute to be set to the newly created vital sign panel.
Click to view child attributes

The coding display of the reference.
derivedFrom
array[json]
Related Observation resource that the Observation is made from.  
This attribute should only be used to link a vital sign to an existing "parent" vital sign panel. It ingests a reference to the vital sign panel's observation. This observation ID can be found using the [Observation Search](/api/observation/#search).  
If this field is omitted on a vital sign observation, a vital sign panel will automatically be created.   
It is important to note that each vital sign panel can only contain a single vital sign of each type. Adding a duplicate of a vital sign will result in a 422 error: "Vital sign reading already exists for the given reading".

type
string
Type the reference refers to (e.g. "Observation", "QuestionnaireResponse").
component
array[json]
Component results  
This attribute is only used for blood pressure, as it has two components (systolic and diastolic).   
  - These components are added to a vital sign observation by including their `code` and `valueQuantity`.
  - The components are what will be stored in the database; however, they will not display on the UI. The `Observation.valueString` will be the attribute that displays on the UI.

# Organization

Source: https://docs.canvasmedical.com/api/organization/

### 
A formally or informally recognized grouping of people or organizations formed for the purpose of achieving some form of collective action. Includes companies, institutions, corporations, departments, community groups, healthcare practice groups, payer/insurer, etc.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-organization.html>   
Organizations come from four different Canvas data types: Organizations, Vendors, Insurers, and Service Providers. Organizations, Vendors, and Insurers can be managed in Canvas Settings. Service Providers are created automatically when an external provider is referenced, such as when a referral or imaging order is placed, when an external member is added to a patient's Care Team, or when an inbound fax is received. They appear as Organization participants on patient [Care Teams](/api/careteam). FHIR Organizations created by Insurers in Canvas are useful in the [FHIR Coverage](/api/coverage) payor attribute.
### Endpoints

# Pagination

Source: https://docs.canvasmedical.com/api/pagination/

Most endpoints that perform search operations support pagination. For these endpoints, search results are paginated by default, with a `links` section as defined [by FHIR](http://hl7.org/fhir/R4/http.html#paging). The links include urls for `self`, `first`, `next`, and `last` as needed for the searchset. Clients that want all results will need to make use of these links to page through the data. Pagination links will not be provided for an empty result set. A tip when traversing through the pages, if a `next` relation is not in the links list, you are on the last page!
There is a maximum page size (`_count`) that is enforced by the server. This value is at 100 at the time of writing, but can change without warning. Clients must use the links in a search bundle to paginate after an initial search request is sent. When no count is specified in a search, it will default to 10.
In this example, `entry` contains 10 Observation resources - following the relative link marked as `next` returns the remaining 9.
    ```json
    {
        "resourceType": "Bundle",
        "type": "searchset",
        "total": 19,
        "link": [
            {
                "relation": "self",
                "url": "/Observation?_count=10&_offset=0"
            },
            {
                "relation": "first",
                "url": "/Observation?_count=10&_offset=0"
            },
            {
                "relation": "next",
                "url": "/Observation?_count=10&_offset=10"
            },
            {
                "relation": "last",
                "url": "/Observation?_count=10&_offset=10"
            }
        ],
        "entry": [
            {
                "resource": {
                    "resourceType": "Observation",

identifier
array[json]
External identifiers for this patient. None of these identifiers are surfaced on the patient chart, but they may help you correlate the Canvas patient with records in your own systems.
The MRN is auto-issued by Canvas; do not include it on create.
Click to view child attributes
use
enum [ usual | official | temp | secondary | old ]
Purpose of this identifier. Defaults to **usual** if omitted.
system
string required
Free-text namespace for the value (e.g., "HealthCo", or a URL).
value
string required
The identifier value. Must be 1–255 characters.

Additional entries with `use`: **nickname** , **maiden** , or **old** are accepted: the first item in the `given` list of a **nickname** entry is stored as the patient's preferred name. **maiden** and **old** entries are stored but not displayed in the Canvas UI. Entries with any other `use` value are ignored.   
In the Canvas UI, patients display as `first last suffix (nickname)`, and search supports first, middle, last, suffix, and nickname.
Click to view child attributes
use
enum [ official | nickname | old | maiden ] required
At least one entry with `use`: **official** is required. See the parent description for how each accepted value is handled.
family
string required
Family name (often called 'Surname'). Required on the **official** entry to populate the patient's last name.
given
array[string] required
Given names. The first item populates the patient's first name; remaining items are joined with a space and stored as the middle name.   
For a **nickname** entry, only the first item is read and stored as the patient's preferred name. Surrounding whitespace is trimmed, and a value that is empty or whitespace-only is stored as an empty preferred name.
prefix
array[string]
Parts that come before the name (e.g., "Dr.", "Mr."). Stored but not displayed in the Canvas UI.
suffix
array[string]
Parts that come after the name (e.g., "Jr.", "III"). Surfaced in the Canvas UI.

#### Patient update
**How updates and deletions to`identifier`, `telecom`, `address`, and `contact` are handled:**  
Each entry returned via Search/Read includes an `id`.   
• If the `id` is included in an entry, Canvas updates the matching record.   
• If the `id` is omitted, Canvas creates a new record.   
• If an entry returned via Search/Read is **not** included in the update body, it is deleted (with the exception of `identifier`, which is only deleted when its `period.end` is in the future).   
The same delete-on-omission behavior applies to the `preferred-pharmacy`, `default-provider`, and `default-location` extensions — their values are dropped if those extensions are not present on update.   
**Other fields**  
Any field that is required on create is also required on update. Optional fields that are not included in the update body retain their stored values.
### Attributes
resourceType
string required
The FHIR Resource name.
id
string
Canvas-issued unique identifier (UUID) for this Patient. It is the same id that appears in the URL of the patient's chart.
Must match the ID in the path parameter.
extension
array[json] required
Canvas-supported FHIR extensions on this resource. Each entry has a `url` identifying the extension, plus either a `valueX` field or — for compound extensions (**race** , **ethnicity** , **tribal-affiliation** , **preferred-pharmacy**) — a nested `extension` array carrying the value. The `url` is matched as an exact string.   
The **birthsex** extension (`http://hl7.org/fhir/us/core/StructureDefinition/us-core-birthsex`) is **required** on create and update.
**Replace semantics on update:** the **preferred-pharmacy** , **patient-default-provider** , and **patient-default-location** extensions follow delete-on-omission — if not included in the request, the stored value is dropped.

identifier
array[json]
External identifiers for this patient. None of these identifiers are surfaced on the patient chart, but they may help you correlate the Canvas patient with records in your own systems.
The MRN is managed by Canvas — do not modify it.   
**Replace semantics:** Each entry returned via Search/Read includes an `id`. Include the `id` to preserve or modify an existing identifier; omit `id` to add a new one. An identifier already in Canvas that is **not** included in the update message will be deleted only if its `period.end` is in the future.
Click to view child attributes
id
string
Canvas-issued identifier for this entry. Include on update to target an existing identifier; omit to create a new one.
use
enum [ usual | official | temp | secondary | old ]
Purpose of this identifier. Defaults to **usual** if omitted.
system
string required
Free-text namespace for the value (e.g., "HealthCo", or a URL).
value
string required
The identifier value. Must be 1–255 characters.
period

end
date
Inclusive end date (YYYY-MM-DD). Defaults to **2100-12-31** if omitted.
active
boolean
Whether the patient is active in the healthcare system. Defaults to `true` if omitted on create.
name
array[json] required
One or more names for the patient. At least one entry is required, and exactly one entry must have `use`: **official** — that entry determines the patient's first/middle/last/prefix/suffix shown across the Canvas UI.   
Additional entries with `use`: **nickname** , **maiden** , or **old** are accepted: the first item in the `given` list of a **nickname** entry is stored as the patient's preferred name. **maiden** and **old** entries are stored but not displayed in the Canvas UI. Entries with any other `use` value are ignored.   
In the Canvas UI, patients display as `first last suffix (nickname)`, and search supports first, middle, last, suffix, and nickname.
**Replace semantics:** Names are not addressed by `id` — the `name` array sent in the update replaces the names stored in Canvas (subject to the use-based rules above). To preserve a previously stored name, include it in the update body.
Click to view child attributes
use
enum [ official | nickname | old | maiden ] required
At least one entry with `use`: **official** is required. See the parent description for how each accepted value is handled.
family
string required
Family name (often called 'Surname'). Required on the **official** entry to populate the patient's last name.
given
array[string] required
Given names. The first item populates the patient's first name; remaining items are joined with a space and stored as the middle name.   
For a **nickname** entry, only the first item is read and stored as the patient's preferred name. Surrounding whitespace is trimmed, and a value that is empty or whitespace-only is stored as an empty preferred name.
prefix
array[string]
Parts that come before the name (e.g., "Dr.", "Mr."). Stored but not displayed in the Canvas UI.
suffix
array[string]
Parts that come after the name (e.g., "Jr.", "III"). Surfaced in the Canvas UI.

Click to view child attributes
start
date
Inclusive start date (YYYY-MM-DD).
end
date
Inclusive end date (YYYY-MM-DD).
telecom
array[json]
Patient contact points (phone / email / fax / etc.).   
Phone and email entries are surfaced in the Canvas UI. Other systems are accepted and stored but are not displayed.
**Replace semantics:** Each entry returned via Search/Read includes an `id`. Include the `id` to preserve or modify an existing contact point; omit `id` to add a new one. A contact point not included in the update message will be deleted.
Click to view child attributes
id
string
Canvas-issued identifier for this contact point. Include on update to target an existing entry; omit to create a new one.
extension
array[json]
Optional flags about the contact point. The `has-consent` extension records that the patient has consented to receive messages at this contact point — set the `url` to **http://schemas.canvasmedical.com/fhir/extensions/has-consent** with `valueBoolean: true`.   
**Note:** Setting `has-consent` here does not send a verification email or text as the Canvas UI does — it bypasses verification and marks the contact point as verified.

**Value Options Supported:**
  - http://schemas.canvasmedical.com/fhir/extensions/has-consent
valueBoolean
boolean required
system
enum [ phone | fax | email | pager | url | sms | other ] required

Purpose of this contact point. Defaults to **home** if omitted.
rank
integer
Preferred order across contact points of the same `system`. Defaults to **1**.
gender
enum [ male | female | other | unknown ] required
Maps to the gender identity field in the Canvas UI. See the [administrative gender ValueSet](https://hl7.org/fhir/R4/valueset-administrative-gender.html).   
**unknown** displays as "choose not to disclose" on the patient chart. **other** displays as "Additional gender category or other, please specify".   
**Note:** If the `genderIdentity` extension is also provided, it overrides this field.
birthDate
date required
Patient's date of birth, formatted **YYYY-MM-DD**.   
Canvas also accepts partial dates: **YYYY-MM** defaults to the 1st of the month, and **YYYY** defaults to January 1st.
deceasedDateTime
datetime
Date/time the patient died. Mutually exclusive with `deceasedBoolean` — provide one or the other.
deceasedBoolean
boolean
Whether the patient is deceased. Use when an exact date/time isn't known.
Setting this to `false` clears the stored datetime of death; setting to `true` does not modify a previously stored datetime of death.
address
array[json]
Address(es) for the patient.
**Replace semantics:** Each entry returned via Search/Read includes an `id`. Include the `id` to preserve or modify an existing address; omit `id` to add a new one. An address not included in the update message will be deleted.

contact
array[json]
Contact parties (e.g., guardian, partner, friend, emergency contact) for the patient. Contact details display on the Patient profile page in the Canvas UI.
**Replace semantics:** Each entry returned via Search/Read includes an `id`. Include the `id` to preserve or modify an existing contact; omit `id` to add a new one. A contact not included in the update message will be deleted.
Click to view child attributes
id
string
Canvas-issued identifier for this contact. Include on update to target an existing contact; omit to create a new one.
relationship
array[json]
Codings describing the relationship of the contact to the patient. Codings can come from the standard `v3-RoleCode` system or from your instance's [configurable contact categories](https://help.canvasmedical.com/articles/8258338559-contact-categories), including the built-in **Emergency contact** category (`code`: `EMC`). Multiple codings can be combined on a single relationship to capture, e.g., both a familial relationship (`SPS` = spouse) and a contact-category role (`EMC` = emergency contact).
Click to view child attributes
coding
array[json]
Code(s) defined by a terminology system.

For the `v3-RoleCode` system, values come from the [PatientRelationshipType ValueSet](https://hl7.org/fhir/R4/valueset-relatedperson-relationshiptype.html).   
For the `contact-category` system, values are the codes configured under [Contact Categories](https://help.canvasmedical.com/articles/8258338559-contact-categories) on your instance — for example, `EMC` (Emergency contact), `ARI` (Authorized for release of information), `POA` (Power of attorney).
display
string
Human-readable name of the coding.
name
json required
A name for the contact.   
Canvas only stores `name.text`. The structured sub-fields (`family`, `given`, `prefix`, `suffix`) are populated on read **only when the contact is itself a Canvas patient** , and are derived from that patient's record — they are not accepted on create or update.
Click to view child attributes

Free-text representation of the contact's full name. The only name field stored for a non-patient contact.
telecom
array[json]
Contact points for this contact.

extension
array[json]
Used by compound extensions whose value is itself a list of extensions. The shape of each inner entry depends on the outer `url`:   
**us-core-race** / **us-core-ethnicity** — one or more inner extensions with `url`: `ombCategory`, `detailed`, or `text`. For `ombCategory` / `detailed`, provide a `valueCoding`. For `text`, provide a `valueString`.   
**us-core-tribal-affiliation** — exactly one inner extension with `url`: `tribalAffiliation` and a `valueCodeableConcept` containing one or more codings (each requires `system`, `code`, and `display`).   
**preferred-pharmacy** — one inner extension with `url`: `ncpdp-id` is **required** ; the NCPDP number goes in `valueIdentifier.value` (must be exactly **7 digits** , left-padded with zeros). Optional inner extensions: `default` (boolean — at most one preferred pharmacy per patient may be set to `true`), `name`, `phone-number`, `address`, `fax-number`, `specialty_type` (each `valueString`).

identifier
array[json]
External identifiers for this patient. None of these identifiers are surfaced on the patient chart, but they may help you correlate the Canvas patient with records in your own systems.
The array always includes the Canvas-issued MRN (an entry with `system`: **http://canvasmedical.com** and a coded `type` of MR). Additional entries are external identifiers added through prior create/update calls or via the Patient profile in the Canvas UI.
Click to view child attributes

Additional entries with `use`: **nickname** , **maiden** , or **old** are accepted: the first item in the `given` list of a **nickname** entry is stored as the patient's preferred name. **maiden** and **old** entries are stored but not displayed in the Canvas UI. Entries with any other `use` value are ignored.   
In the Canvas UI, patients display as `first last suffix (nickname)`, and search supports first, middle, last, suffix, and nickname.
Click to view child attributes
use
enum [ official | nickname | old | maiden ]
At least one entry with `use`: **official** is required. See the parent description for how each accepted value is handled.

Given names. The first item populates the patient's first name; remaining items are joined with a space and stored as the middle name.   
For a **nickname** entry, only the first item is read and stored as the patient's preferred name. Surrounding whitespace is trimmed, and a value that is empty or whitespace-only is stored as an empty preferred name.
prefix
array[string]
Parts that come before the name (e.g., "Dr.", "Mr."). Stored but not displayed in the Canvas UI.

Canvas-issued identifier for this contact point. Include on update to target an existing entry; omit to create a new one.
extension
array[json]
Optional flags about the contact point. The `has-consent` extension records that the patient has consented to receive messages at this contact point — set the `url` to **http://schemas.canvasmedical.com/fhir/extensions/has-consent** with `valueBoolean: true`.   
**Note:** Setting `has-consent` here does not send a verification email or text as the Canvas UI does — it bypasses verification and marks the contact point as verified.

# PaymentNotice

Source: https://docs.canvasmedical.com/api/paymentnotice/

### 
This resource provides the status of the payment for goods and services rendered, and the request and response resource references.  
<https://hl7.org/fhir/R4/paymentnotice.html>  
In Canvas, FHIR PaymentNotice records payments made toward a patient's balance.  
See this [Zendesk article](https://canvas-medical.help.usepylon.com/articles/3813109228-collect-payment) for information about how to collect payments.
### Endpoints
post/PaymentNotice get/PaymentNotice/{id} get/PaymentNotice
post
/PaymentNotice
#### PaymentNotice create
Create a PaymentNotice resource.  
This endpoint can be used to note a payment that has been collected from a patient and deduct the amount from their balance.  
Moreover, this endpoint can be used to denote copayments as well. For that purpose, use the valueReference extension to link the associated Claim for which the copayment is being processed. Adding that extension determines the purpose of action for this endpoint, meaning that it would be treated as a copayment transaction if the Claim reference extension is present.  
**Don't overpay!** Requests that would bring the account balance negative will be rejected. Example: If a patient owes $5, Canvas would reject a PaymentNotice with a value that is greater than $5. Balance can only go negative if performing copayments as customers could be charged prior to recieveing a medical service.  
A created payment notice can be found in Canvas by going to the patient's chart, and clicking the paper icon in the top right corner. The created payment notice will be displayed under receipts. The "Originator" will be automatically set to Canvas Bot.  
As payment notices are created, they will be applied to charges in chronological order of creation date, from oldest to newest.

# Provenance

Source: https://docs.canvasmedical.com/api/provenance/

### 
Provenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource. Provenance provides a critical foundation for assessing authenticity, enabling trust, and allowing reproducibility. Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance. Provenance statement indicates clinical significance in terms of confidence in authenticity, reliability, and trustworthiness, integrity, and stage in lifecycle (e.g. Document Completion - has the artifact been legally authenticated), all of which may impact security, privacy, and trust policies.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-provenance.html>   
In Canvas a Provenance record is created each time the following data types are created or updated in the Canvas database:
  - AllergyIntolerance
  - CarePlan
  - CareTeamMembership
  - Condition
  - ConsolidatedImmunization
  - Coverage
  - Device
  - DiagnosticReport
  - DocumentReference
  - Encounter
  - Goal
  - Observation
  - Patient
  - Prescription
  - Procedure
  - ServiceRequest
  - UpdateGoal

# Questionnaire

Source: https://docs.canvasmedical.com/api/questionnaire/

### 
A structured set of questions intended to guide the collection of answers from end-users. Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection.  
<https://hl7.org/fhir/R4/questionnaire.html>  
See our [article](https://canvas-medical.help.usepylon.com/articles/7017593857-creating-questionnaires) for information about how to create and upload a questionnaire in Canvas.  
**Understanding Canvas Questionnaires**  
_Codings_  
All questionnaires must have coding, and all response options within a question on a questionnaire must have codings.  
_Question Types_  
Canvas supports 4 different type of questions:  
1\. Multi select response questions are denoted with:  
`"type": "choice", "repeats": true`  
2\. Single select response questions are denoted with:  
`"type": "choice", "repeats": false`  
3\. Free text response questions are denoted with:  
`"type": "text", "repeats": false`  
4\. Date response questions are denoted with:  
`"type": "date", "repeats": false`  
Questions can be reused in multiple questionnaires, but any given question code should only appear once within a particular questionnaire.
### Endpoints

# QuestionnaireResponse

Source: https://docs.canvasmedical.com/api/questionnaireresponse/

### 
A structured set of questions and their answers. The questions are ordered and grouped into coherent subsets, corresponding to the structure of the grouping of the questionnaire being responded to.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-questionnaireresponse.html>  
See this [article](https://help.canvasmedical.com/articles/7017593857-creating-questionnaires) for information about how to build questionnaires in Canvas.  
Questionnaires can map to four different commands in the Canvas UI depending on what the use case in charting is set to:
  - [Questionnaire](https://canvas-medical.help.usepylon.com/articles/5651999344-command-questionnaire)
  - [Structured Assessment](https://canvas-medical.help.usepylon.com/articles/8805008571-command-structured-assessment)
  - [Review of Systems](https://canvas-medical.help.usepylon.com/articles/9046024531-command-review-of-systems)
  - [Physical Exam](https://canvas-medical.help.usepylon.com/articles/1745103290-command-physical-exam)
QuestionnaireResponse resources contain answers to questions in a Questionnaire resource. Use the [Questionnaire search endpoint](/api/questionnaire/#search) to find Questionnaire resources.
### Endpoints
post/QuestionnaireResponse get/QuestionnaireResponse/{id} put/QuestionnaireResponse/{id} get/QuestionnaireResponse
post
/QuestionnaireResponse
#### QuestionnaireResponse create
Create an QuestionnaireResponse resource.
### Attributes
resourceType
string
The FHIR Resource name.
extension
array[json]
Additional content defined by implementations  
Canvas supports a note identifier extension on this resource for create, read, update, and search interactions. The note identifier can be used with the [Canvas Note API](/api/note).  
**Important:** For create interactions, Canvas recommends sending the note identifier extension or the Encounter reference, but not both. If both are supplied, they must both refer to the same note.  
Click to view child attributes
url
string required
Reference that defines the content of this object.
**Value Options Supported:**
  - For note identifier we have a url of `http://schemas.canvasmedical.com/fhir/extensions/note-id`
valueId
string
The valueId field is used for the Note extension and will be the note's unique identifier
questionnaire
string
Form being answered.  
The `questionnaire` field contains an absolute URL to a Questionnaire, e.g. `https://fumage-example.canvasmedical.com/Questionnaire/ac1da1a4-ccc4-492e-a9e0-7f70a58c2129`. Questionnaire IDs can be obtained using the [Questionnaire search endpoint](/api/questionnaire/#search). Either the `questionnaire` attribute or the URL extension under `_questionnaire` must be provided.
_questionnaire
json
This attribute contains the extensions for the `questionnaire` attribute.
Click to view child attributes
extension
array[json]
Extensions on the `questionnaire` attribute. Supported extensions include questionnaire name and URL.
To create a QuestionnaireResponse that responds to a non-FHIR questionnaire, like an external PDF file, the URL extension must be provided, and the `questionnaire` attribute must be omitted. In this scenario, there is no `Questionnaire` resource referenced by the `questionnaire` attribute. Question text must be provided for each `item`, and only `valueString` answers are permitted.  
When a QuestionnaireResponse is created in this manner, it does **not** result in the insertion of a command into a note.

encounter
json
Encounter created as part of.  
If `encounter` is provided, the QuestionnaireResponse will be added to the existing encounter (note). If it is not provided, a new data import note will be created. It will be inserted into the timeline using the timestamp passed in `authored`.  
**Canvas does not currently support concurrent creation of resources on the same encounter.** Please avoid issuing concurrent requests that reference the same encounter to this endpoint, or to any other endpoints that reference encounters. It is OK to issue concurrent requests to these endpoints as long as the requests reference different encounters.

item
array[json]
Groups and questions  
The `item` attribute contains the answers to the questions in the Questionnaire. The `item` attribute in QuestionnaireResponse corresponds to the `item` attribute in Questionnaire payload, and are related via the `linkId` attribute. If a question's answer is omitted, it will be left unanswered in Canvas. However, if it is a questionnaire tied to a scoring function, Canvas requires all questions to be answered in order to accurately score the Questionnaire.  
Each `item` must contain a `linkId` and `answer` attributes. The `answer` attribute is a list of answers for the question referred to by the `linkId`.  
Canvas supports the following question formats:  
• Free text  
• Single choice  
• Multiple choice  
• Date  
Answers to free text questions are provided as a `valueString`. Answers to decimal questions are provided as a `valueDecimal`. Answers to single and multiple choice questions are provided as a `valueCoding`. Answers to date questions are provided as a `valueDate`, an ISO 8601 calendar date (`YYYY-MM-DD`). See the request and response examples for more information.

### Responses
201 Created
The server has successfully processed the request; the new resource has been created and is now ready for interaction.  
Canvas returns the created resource's id as a UUID within the `location` header and a `null` response body.
### Errors
400 Bad Request
The request was invalid or cannot be otherwise served. An accompanying error message will explain further.
401 Unauthorized
The request requires user authentication.
403 Forbidden
The request requires user authorization.
405 Method Not Allowed
The request performs an operation that is either not supported or allowed.
422 Unprocessable Entity
The request cannot be processed due to semantic issues or conflicts with the database state.
**Validation Errors**  
_Beware of ambiguous choices!_  
If the questionnaire contains a question with identical codings for different choices, Canvas will not know which of the choices were selected. In this case, Canvas will reject the request. For the request to succeed, each question must have a uniquely coded set of choices. Choice codings can be reused across questions, but not within them.If this scenario occurs, you will get the error message: `Question received a response option code: {code} that belongs to more than one option response`  
_More Coding Validation_  
The system is the `valueCoding` answer needs to match the system that the question specified in the Questionnaire Search Response. If it does not, you will get the error: `Question expects answer of code system {system} but {system} was given`  
If a code is passed that does not exist for that question in Canvas, you will get the error: `Question received an invalid response option code: {code}`  
_Answer Validation_  
For single or free text questions, if more than one answer is provided, you will get the error: `Question of type {type} is expecting at most one answer`  
For free text questions, the answer object must include a `valueString` or you will get the error: `Question of type TXT expects a valueString answer`  
For single or multiple choice questions, the answer objects must include a `valueCoding` or you will see one of these errors:  
`Question of type SING expects a valueCoding answer`  
`Question of type MULT expects a valueCoding answer`  
For date questions, the answer object must include a `valueDate` or you will get the error: `Question of type DATE expects a valueDate answer`

# Quickstart

Source: https://docs.canvasmedical.com/api/quickstart/

##  Authentication 
To access our FHIR API, you will need to request an access token and refresh it periodically. You can refer to our [Authentication Documentation](/api/customer-authentication) and [Authentication Best Practices](/api/authentication-best-practices) to get you set up. Access tokens expire 10 hours after they are created. You can and should reuse access tokens to reduce the number of tokens that are valid at any given time.
##  Create a patient 
Let's start by creating a patient. we've gone ahead and generated some boilerplate Patient info that includes all of the minimum required parameters for a Create a Patient request.
    ```shell
    curl -i --location 'https://fumage-<sandbox-name>.canvasmedical.com/Patient' \
         --header 'Authorization: Bearer <bearer-token>' \
         --header 'Content-Type: application/json' \
         --data '{
            "resourceType": "Patient",
            "extension": [
                {
                    "url": "http://hl7.org/fhir/us/core/StructureDefinition/us-core-birthsex",
                    "valueCode": "F"
                }
            ],
            "gender": "female",
            "active": true,
            "name": [
                {
                    "use": "official",
                    "family": "Mitko",
                    "given": [
                        "Salina"
                    ]
                }
            ],
            "birthDate": "1949-11-13"
        }'
    ```
To execute this command, first:
Replace  with your sandbox name Replace  with your Bearer token you learned about above in the Authentication Section Hit enter and your first patient, Salina Mitko, is created!
Navigate to the Canvas UI (sandbox or production instance) and log in using the credentials provided, search for Salina in the top-left search box and visit the first search result to find her chart.
For more detail about making Patient Create requests, check out the API documentation for Patient Create.
> **Info:** As part of the request's response, you will see a patient ID within the location: header. Copy the ID value between Patient/ and / history - you will need it to create an appointment in the next step.  
>   
>  Also to note that ID will match the ID you will find in your browser when you navigate to the patient's chart: https://{customer}.canvasmedical.com/patient/{patientID}
##  Create an Appointment 
We have our first patient and now want to book their first appointment. But before we can book their appointment we will need to find a practitioner.
If you are using one of our canvas sandboxes, there will already be a demo staff member loaded in the instance.
Run the following request to find the list of Practitioners in your organization. Again you will need to replace the  and  with the same values you used to create your patient above.
    ```shell
    curl --location 'https://fumage-<sandbox-name>.canvasmedical.com/Practitioner' \
    --header 'Content-Type: application/fhir+json' \
    --header 'Authorization: Bearer <bearer-token>' | jq
    ```
You will then get a response similar to:
    ```shell
    {
      "resourceType" : "Bundle",
      "type" : "searchset",
      "total" : 1,
      "entry" : [
        {
          "resource" : {
            "resourceType" : "Practitioner",
            "id" : "e766816672f34a5b866771c773e38f3c",
            "identifier" : [
              {
                "system" : "http://hl7.org/fhir/sid/us-npi",
                "value" : "1834494258"
              }
            ],
            "name" : [
              {
                "use" : "usual",
                "text" : "Youta Priti MD",
                "family" : "Priti",
                "given" : [
                  "Youta"
                ]
              }
            ]
          }
        }
      ]
    }
    ```
Copy down the value for "id". This is the Practitioner ID you will need to create your first appointment.
Now we have our Patient ID and Practitioner ID. We're ready to create our first appointment.
Now lets set up the cURL command to create the appointment. Again you will need to replace the  and . Then replace  and  with the values copied in the last two requests. This appointment will create a Telehealth Appointment. You might want to update the start and end dates to be today's date for easy find-ability on the calendar view.
    ```shell
    curl -i --location 'https://fumage-<sandbox-name>.canvasmedical.com/Appointment' \
      --header 'Authorization: Bearer <bearer-token>' \
      --header 'Content-Type: application/json' \
      --data '{
        "resourceType": "Appointment",
        "status": "booked",
        "appointmentType": {
            "coding": [
                {
                    "system": "http://snomed.info/sct",
                    "code": "448337001",
                    "display": "Telemedicine consultation with patient (procedure)"
                }
            ]
        },
        "description": "Weekly check-in.",
        "supportingInformation" : [
          {
            "reference" : "Location/1"
          }
        ],
        "start": "2022-02-19T13:30:00.000Z",
        "end": "2022-02-19T14:00:00.000Z",
        "participant": [
            {
                "actor": {
                    "reference": "Practitioner/<practitioner-id>"
                },
                "status": "accepted"
            },
            {
                "actor": {
                    "reference": "Patient/<patient-id>"
                },
                "status": "accepted"
            }
        ]
    }'
    ```
If you navigate to the correct date you used for start and end in the request above on the Schedule of your Canvas home page, you will see your first appointment. You should also be able to see the appointment when navigating to the patient's chart.
For more detail about making Appointment Create requests, check out the API documentation for [Appointment Create](ref:create) .

# ServiceRequest

Source: https://docs.canvasmedical.com/api/servicerequest/

### 
A request for a service to be performed for a patient, such as imaging, laboratory testing, or referral.  
<https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-servicerequest.html>  
ServiceRequest represents multiple Canvas services:
  - Imaging orders (e.g., CT, MRI, X-ray) - [Ordering imaging study](https://canvas-medical.help.usepylon.com/articles/2615916315-image-command) \- Laboratory orders (e.g., hemoglobin/hematocrit) - [Placing a lab order](https://canvas-medical.help.usepylon.com/articles/3065191197-placing-a-lab-order) \- Referrals (e.g., patient referral to specialist) - [Referring a patient](https://canvas-medical.help.usepylon.com/articles/8339414277-command-referrals) The ServiceRequest surface reflects these orders via standardized coding:
  - `category` uses SNOMED CT to represent the order category (e.g., Imaging, Laboratory procedure, Referral/Evaluation procedure) - `code` uses LOINC to represent the requested test/procedure

Arbitration and Class Action Waiver. This Section includes an arbitration agreement and an agreement that all claims will be brought only in an individual capacity (and not as a Class Action or other representative proceeding). Please read it carefully. You may opt out of the arbitration agreement by following the opt out procedure described below. Informal Process First. You agree that in the event of any dispute between you and us, you will first contact us and make a good faith sustained effort to resolve the dispute before resorting to more formal means of resolution, including without limitation any court action. Arbitration Agreement. Under this Agreement, you agree that any dispute, claim, or controversy arising out of or relating to this Agreement your use of the Developer Tools, or relating in any way to the communications between you and us or any other user of Use will be finally resolved by confidential binding arbitration administered by Judicial Arbitration and Mediation Services ("JAMS") in San Francisco, California, or another forum mutually agreed upon by you and us. The arbitration will be conducted according to the JAMS Expedited Procedures for arbitration by a single arbitrator nominated jointly by you and us. If JAMS is not hearing consumer commercial disputes at the time, we may select another arbitral body at its sole discretion. The arbitrator's award will be binding and may be entered as a judgment in a court of competent jurisdiction. This clause shall not preclude us from seeking provisional remedies in aid of arbitration from a court of appropriate jurisdiction, or to seek injunctive relief in a court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of our copyrights, trademarks, trade secrets, or patents. This arbitration agreement does not (a) govern any Claim by us for infringement of our intellectual property or access to the Developer Tools that is unauthorized or exceeds authorization granted in this Agreement or (b) bar you from making use of applicable small claims court procedures in appropriate cases.

Class Action Waiver. Any Claim must be brought in the respective party's individual capacity, and not as a plaintiff or class member in any purported class, collective, representative, multiple plaintiff, or similar proceeding ("Class Action"). The parties waive any ability to maintain any Class Action in any forum. If the Claim is subject to arbitration, the arbitrator will not have authority to combine or aggregate similar claims or conduct any Class Action nor make an award to any person or entity not a party to the arbitration. Any claim that all or part of this Class Action Waiver is unenforceable, unconscionable, void, or voidable may be determined only by a court of competent jurisdiction and not by an arbitrator. The parties understand that any right to litigate in court, to have a judge or jury decide their case, or to be a party to a class or representative action, is waived, and that any claims must be decided individually, through arbitration.
If this Class Action waiver is found to be unenforceable, then the entirety of this Arbitration and Class Action Waiver Section, if otherwise effective, will be null and void. The arbitrator may award declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party's individual claim. If for any reason a claim proceeds in court rather than in arbitration, you and us each waive any right to a jury trial.
Ownership. Subject to the licenses and rights specified in this Agreement, nothing in this Agreement transfers or assigns to us any of your intellectual property rights in the Connected Services or your trademarks, logos, or other brand insignia nor does this Agreement transfer or assign to you any of our intellectual property rights in the Application and Developer Tools or our trademarks, logos, or other brand insignia. Support. This Agreement does not entitle you to receive from us any technical, customer, or sales support of the Application, Developer Tools, or Connected Services. You (not us) are solely responsible for providing technical assistance and other support related to the Connected Services. Miscellaneous. This Agreement constitutes the entire agreement between you and us regarding your use of the Developer Tools.

# How to add additional fields to the scheduling appointment fields

Source: https://docs.canvasmedical.com/guides/appointments-additional_fields/

This guide explains how to add additional fields that will appear when scheduling an appointment. With this, you can define custom fields, and the information will be stored as appointments metadata.
##  What you'll learn: 
  - Use the [`AppointmentMetadataCreateForm`](/sdk/appointment-metadata-create-form-effect) effect to display additional fields when scheduling an appointment.
  - Use the [`FormField`](/sdk/appointment-metadata-create-form-effect/#formfield) class to create fields
##  Appointment Metadata Create form plugin 
####  1\. FormField 
To create the form, we need to specify which items will be included. For this, we use the [`FormField`](/sdk/appointment-metadata-create-form-effect/#formfield) class, where we can define our inputs and their attributes.
    ```python
    from canvas_sdk.effects.appointments_metadata import FormField, InputType
    FormField(
        key='state',
        label='State',
        type=InputType.TEXT,
        required=False,
        editable=True,
        value="CA"
    ),
    ```
####  2\. AppointmentMetadataCreateFormEffect 
The next step is to add these fields to the effect so they can be used to build the form.
    ```python
    from canvas_sdk.effects.appointments_metadata import AppointmentsMetadataCreateFormEffect, FormField, InputType
    AppointmentsMetadataCreateFormEffect(form_fields=[
        FormField(
            key='state',
            label='State',
            type=InputType.TEXT,
            required=False,
            editable=True,
            value="CA"
        ),
        ...,
    ])
    ```
####  3\. The plugin 
Here's an example of a complete plugin showcasing the different input types.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.appointments_metadata import AppointmentsMetadataCreateFormEffect, InputType, FormField
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    # Inherit from BaseHandler to properly get registered for events
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.APPOINTMENT__FORM__GET_ADDITIONAL_FIELDS)
        def compute(self) -> list[Effect]:
            form = AppointmentsMetadataCreateFormEffect(form_fields=[
                FormField(
                    key='state',
                    label='State',
                    type=InputType.TEXT,
                    required=False,
                    editable=True,
                ),
                FormField(
                    key='occupation',
                    label='Occupation',
                    type=InputType.SELECT,
                    required=False,
                    editable=True,
                    options=["Engineer", "Teacher", "Other"]
                )
            ])
            return [form.apply()]
    ```
####  4\. The Output 
Below, you can see how it will appear in the app — these fields will be stored as appointments metadata.

# Audit Logging and Telemetry

Source: https://docs.canvasmedical.com/guides/audit-logging-and-telemetry/

Canvas records an attributed audit trail of activity in your instance and makes it available to you through several export paths. This page describes what is captured, how long it is retained, and how to get it out — whether for an internal investigation, a compliance review, or ingestion into your own SIEM.
##  What is captured 
Canvas maintains a per-record audit trail. Each entry identifies the record type acted on, the action taken, the acting user, the patient context where applicable, and a UTC timestamp.
Action| Captured| Granularity  
---|---|---  
Create| Yes| Per record, per model, attributed to the acting user  
Edit or change| Yes| Per record, with full authorship history  
Delete, void, or enter-in-error| Yes| Per record, covering hard deletion, soft deletion, and marking entered-in-error  
Print| Yes| Note-print events  
Chart access| Yes| Chart-open events, attributed to the user opening the chart  
Individual record reads within an already-opened chart are not enumerated separately; chart access is recorded at the point the chart is opened.
Alongside the record audit trail, Canvas captures:
  - **Authentication events** — sign-in successes and failures, and account lockouts.
  - **Administrative activity** — configuration and permission changes, surfaced in the admin console and protected there against edit and deletion.
  - **Staff activity reports** — generated nightly.
###  Change history through FHIR Provenance 
Authorship and change history are also exposed as FHIR `Provenance` resources across supported resource types, giving you a queryable record of who created or revised a resource and when. See the [Provenance API](/api/provenance/) reference for supported resource types and query parameters.
Clinical notes additionally carry in-application revision history, visible to users directly in the chart.
##  Retention 
Audit records are retained in the live, queryable index for **90 days**. Older indices are archived to durable object storage and remain recoverable well beyond that window. If you require retrieval of archived records, contact Canvas support with the date range you need.
Retention requirements that exceed the live window are best served by exporting on a schedule into your own retention tier — see the export paths below.
##  Viewing the audit trail in the application 
Authorized users can browse the audit trail in a filterable, searchable, read-only view built into the application. It surfaces recorded events without allowing any change to them.
The view is enabled per instance by Canvas; contact Canvas to turn it on for your instance. Once enabled, access still requires an explicit permission that no default role carries, so a customer administrator must grant it intentionally.
This view reviews audit data in place; it does not extract or export anything. To get audit data out of Canvas, see the paths below.
##  Getting audit data out 
Five supported paths exist today. Which one fits depends on whether you need a point-in-time extract, an ongoing feed, or ad-hoc investigation.
Path| Best for| Interface  
---|---|---  
Audit Report export| Point-in-time extract of administrative and record-level audit events| Admin console  
[FHIR Provenance API](/api/provenance/)| Authorship and change history for specific resources| FHIR API  
FHIR Bulk Data export| Large-scale structured extraction| FHIR API — see [Electronic Health Information (EHI) Export](/documentation/ehi-export/)  
Read-only replica database| Ad-hoc investigation, custom reporting, scheduled ingestion| SQL  
Streaming to a SIEM| Continuous security monitoring in your own SIEM| HTTPS push  
###  Audit Report export 
The Audit Report is generated from the admin console and exports the audit trail for a selected date range. This is the most direct route to the record-level events described above.
> **Warning:** Audit Report access is permission-based. If you need access, your internal administrators can work with Canvas support to assign it to the appropriate groups.
###  Read-only replica database 
Instances can be provisioned with a read-only replica for direct SQL access. This is the most flexible path for building custom audit reporting with your own SQL queries, and for ad-hoc or scheduled extraction into an external system. For continuous security monitoring, use the SIEM export below instead.
###  Streaming to a SIEM 
Canvas pushes audit events to an HTTPS endpoint you control. Events use the Open Cybersecurity Schema Framework (OCSF) schema — an open, vendor-neutral format that SIEMs understand — and are delivered as batched newline-delimited JSON (NDJSON).
Delivery is at-least-once, so the receiving system must tolerate occasional duplicate events. "Delivered" means your endpoint accepted the batch with an HTTP 2xx response; it is not a guarantee that every event became queryable in your SIEM. Reconcile against the events you actually receive.
Delivery is also durable: Canvas stores each audit event and keeps trying to deliver it, retrying when your endpoint is temporarily unreachable, so a brief outage at your end does not immediately drop events from the feed. If you suspect a gap in what your SIEM received, the same events are retained in Canvas (see Retention above) and remain available through the other audit paths on this page, so you can reconcile or recover them there. If a delivery problem persists, contact Canvas.
The export never includes patient names, dates of birth, or clinical values — only opaque identifiers, booleans, and enumerated values. Identifiers are direct Canvas identifiers by default, or pseudonymized on request.
> **Info:** The SIEM export is opt-in and enabled per instance by Canvas — it is not a self-serve toggle. Request it through your Canvas representative, who sets up your destination endpoint and the credentials Canvas presents to it.
##  Plugin activity 
Plugins execute in an isolated runner, and their activity is instrumented per plugin, including outbound HTTP calls made through the SDK. Plugins can also emit their own application logs — see [Plugin Logs](/sdk/plugin-logs/).

# Choosing Your Patient Experience

Source: https://docs.canvasmedical.com/guides/choosing-your-patient-experience/

The first decision when building a patient-facing experience on Canvas isn't technical — it's about **how much of that experience you want to own**. Canvas gives you a spectrum: turn on our built-in patient portal as-is, extend it with plugins, or build your own patient app entirely and use Canvas as the clinical backend. This guide helps you pick the path that fits your product, team, and timeline — and points you to the how-to docs once you've decided.
> **Info:** There's no wrong door, and you're not locked in. Most teams start with the built-in portal and add custom pieces over time — the paths below are complementary, not one-way.
##  The three paths 
| **Use the built-in portal**| **Extend the built-in portal**| **Build your own**  
---|---|---|---  
**Who builds the UI**|  Canvas| Canvas + your plugins| You  
**Effort**|  Lowest| Medium| Highest  
**Control over look & flow**| Configuration| Configure, plus inject widgets, applications, and logic| Total  
**Patient data**|  Handled for you| Handled for built-in pages; you supply data to your own widgets & applications (Canvas data module, Custom Data, or external sources)| You read & write it via Canvas APIs  
**Best when**|  You want a working, compliant portal fast| The built-in portal is close, but you need extra pages, branding, or custom rules| You have (or want) your own branded app and use Canvas as the source of truth  
##  How to choose 
* * *
##  Path 1 — What's already built into Canvas 
When you sign with Canvas, you already have a full patient portal — no build, no plugins, nothing to stand up. Patients can log in (with their email, phone number, or username, plus a password) and use it from day one, and Canvas hosts it and handles the login, data, and compliance for you.
Out of the box it includes **messaging, payments, labs, and a contact page**. Other pages — **scheduling, My Health, health records, consents, and self-registration** — are built in too and ready to switch on whenever you want them.
Everything in this path is **configuration only — no plugins or code**. You decide which built-in pages appear and set basic branding; that's the whole effort.
###  Built-in pages you can turn on or off 
Each page is toggled with a **Constance** setting, managed by Canvas Support — so [contact Support](https://canvas-medical.help.usepylon.com/) to change them. For a full walkthrough, see [Managing the Patient Portal](https://canvas-medical.help.usepylon.com/articles/7348270931-managing-the-patient-portal).
Setting| Page| What patients can do| Default  
---|---|---|---  
`PATIENT_APP_MESSAGING`| Messaging| Securely message their care team| `True`  
`PATIENT_APP_PAYMENTS`| Payment| View and pay outstanding balances| `True`  
`PATIENT_APP_LABS`| Lab| View their lab results| `True`  
`PATIENT_APP_CONTACT`| Contact| See the practice's contact information| `True`  
`PATIENT_APP_MY_HEALTH`| My Health| Review conditions, medications, allergies, and related clinical info| `False`

`PATIENT_APP_APPOINTMENTS`| Scheduling flow| Book and view appointments| `False`  
`PATIENT_APP_CONSENTS`| Consents| Review and complete consents| `False`  
`PATIENT_APP_REGISTER`| Register| Self-register from the login page| `False`  
**Other portal settings:**
Setting| Controls| Default  
---|---|---  
`ENABLE_PATIENT_PORTAL`| Whole portal on/off| `True`  
`ALLOW_PATIENT_DOCUMENT_UPLOADS`| Patient document uploads on "My Health"| `False`  
`PATIENT_APP_USERS_EMAIL_ONLY`| Email-only login (access mode, not a page)| `False`  
`PATIENT_APP_BANNER`| Banner text on the portal login page| `""`  
> **Warning:** Defaults are mixed, not all-off. Messaging, Payments, Labs, and Contact are on out of the box; My Health, Health Records, Appointments, Consents, and Register are off. So you typically turn off the stock pages you don't want and turn on the ones you do — rather than enabling everything from scratch.
###  Branding 
You can put your organization's identity on the portal without building anything:
  - **Logo** — your organization's logo is shown on the login page and throughout the portal. It's configured on your Canvas organization; until you provide one, the default Canvas logo appears. Work with Canvas to set it.
  - **Banner message** — `PATIENT_APP_BANNER` sets a short greeting above the login card.
  - **Email sender for patient messages** — message and notification emails to patients are sent with **your organization's name** as the sender, from the address in your organization's `defaultEmail` setting (default `do-not-reply@canvasmedical.com`). You can change that address; using your own domain may require sender authentication set up with Canvas.
What stays **Canvas-driven** and isn't branded per organization:
  - **The portal URL** — patients sign in at `https://<your-instance>.canvasmedical.com/app/`.
  - **The login flow** — the sign-in and verification screens are Canvas's.
  - **Sign-in & verification emails** — these are sent from a fixed `no-reply@canvasmedical.com` (a separate path from the patient-message sender above), so they can't be rebranded.
> **Info:** Want your own domain and login flow end to end? That's Path 3 — build your own app and use Canvas as the backend.

##  Path 2 — Extend the built-in portal with plugins 
The built-in portal is a strong starting point — but it's rarely _exactly_ what you want. Path 2 is where you make it feel like **yours** : add the cards, pages, and rules your patients and workflows actually need, while Canvas keeps hosting the portal and handling login, data, and compliance. You never stand up your own app.
Under the hood, every extension is a plugin that **reacts to a portal event and returns an effect**. As patients move through the portal, your handler can add a widget, render a page, filter appointment slots, and so on.
New to plugins? Start with [Your First Plugin](/guides/your-first-plugin-with-claude-code/), then keep the [Patient Portal config hub](/sdk/patient-portal/) and the [portal events](/sdk/events/) handy. And for inspiration, the community-run [Medical Software Foundation library](https://github.com/medical-software-foundation/canvas) has production-ready portal extensions you can install or learn from — several are linked below.
Here's what you can do — mix and match as many as you like.
###  Personalize the landing page with widgets 
The portal home is the first thing patients see after logging in, and it's the easiest place to add value. **Widgets** are cards you render there: a "your next appointment" summary, an outstanding-balance nudge, a care-gap reminder ("you're due for a flu shot"), links to your own resources — anything you can compute for that patient.
You control what each card shows, pulling from the Canvas data module, your plugin's Custom Data, or an external service.
See [Portal Landing Page Widgets](/sdk/patient-portal/#portal-landing-page-widgets) and the [Custom Landing Page guide](/guides/custom-landing-page/) for the exact documentation on how to build them. And you don't have to start from a blank file — there's a ready-made [patient_portal_plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_portal_plugin) in our open-source examples repo you can install as-is or use as a reference and starting point.
###  Shape self-scheduling 
Self-scheduling is powerful, but you'll usually want guardrails. Filter or reorder the slots a patient can book _before they see them_ — keep new patients on longer visit types, hide same-day slots, steer certain reasons to specific providers, or enforce your booking policies.
See [Shape Self-Scheduling](/sdk/patient-portal/#shape-self-scheduling) · SDK example: [patient_portal_search_appointments_slots_plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_portal_search_appointments_slots_plugin).
Real-world example (MSF):
  - [urgent-care-self-scheduler](https://github.com/medical-software-foundation/canvas/tree/main/extensions/urgent-care-self-scheduler) — adds a "Need to be seen today?" portal card and a full self-booking flow that offers only credentialed providers, blocks duplicate bookings, and pre-populates the visit note. A good end-to-end model.
###  Tailor appointment cards 
Fine-tune the actions on each appointment. Hide **Cancel** or **Reschedule** when your policy says so (for example, no reschedule within 24 hours of the visit), or add a **telehealth join link** to virtual appointments — decided per appointment.
See [Customize Appointment Cards](/sdk/patient-portal/#customize-appointment-cards).
Real-world example (MSF):
  - [portal_disable_cancel_appts](https://github.com/medical-software-foundation/canvas/tree/main/extensions/portal_disable_cancel_appts) — answers the "can this appointment be canceled?" check with _no_ , removing the self-service Cancel action so cancellations route through staff.
###  Surface forms and react to responses 
Meet patients with the right questionnaire at the right moment — an intake packet before a first visit, a PHQ-9 for a behavioral-health appointment, a post-visit survey — and act on what they submit. Forms are surfaced to the patient when they log in to the portal: you choose which ones appear, then react to responses to store the answers or trigger follow-up. Responses are saved as Interviews, and you can even generate a Questionnaire command in the patient's note.
See the [Patient Portal effects → Forms](/sdk/patient-portal/#forms) for the technical reference.
###  Automate login and activation 
Getting patients into the portal doesn't have to be manual. Automatically **invite** patients to activate their account when they're ready — for example, once you've confirmed a good email or phone — instead of having staff send invitations one at a time. You can also keep a patient's portal **login in sync** when their email or phone changes, and **verify** a contact point before you rely on it to invite them or send messages.
See [User Login](/sdk/patient-portal/#user-login) for automating invitations and keeping the login in sync, and [Send Contact Verification](/sdk/effect-send-contact-verification/) for confirming a contact point first.
###  Control the navigation layout 
Decide which items appear in the portal navigation and in what order — and do it **conditionally per patient**. Surface a page only to patients in a certain program, reorder the menu so what matters most comes first, or hide built-in items you don't use. The navigation isn't fixed; you compute it for each patient every time the portal loads.
See [Configure Portal Menu Items](/sdk/patient-portal/#configure-portal-menu-items).
###  Add your own pages 
Need more than a card? Add entire patient-facing **pages** with an Application scoped to the patient portal — a program dashboard, an intake wizard, a financial-assistance flow, an education library. The page lives inside the portal (same URL, same login, same navigation), but its UI and logic are entirely yours.
This is also how you **replace a built-in page you don't love**. Don't like how the stock My Health page presents conditions, medications, and allergies? Build your own version exactly the way you want it, then turn off the built-in page with its Path 1 toggle (`PATIENT_APP_MY_HEALTH`) so patients only ever see yours. The same works for any built-in section — keep the stock pages that suit you and swap out the ones that don't, one at a time.
See the [Applications handler](/sdk/handlers-applications/) and [Configure Portal Menu Items](/sdk/patient-portal/#configure-portal-menu-items) for surfacing your page in the portal navigation · SDK examples: [example_patient_portal_page](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/example_patient_portal_page), [patient_app_schedule](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/patient_app_schedule).
Real-world examples (MSF):
  - [patient-portal-profile](https://github.com/medical-software-foundation/canvas/tree/main/extensions/patient-portal-profile) — adds a read-only **My Profile** page (demographics, care team, preferred pharmacy).
  - [portal-content](https://github.com/medical-software-foundation/canvas/tree/main/extensions/portal-content) — builds richer **My Records** and **My Profile** pages (visit notes, labs, imaging, letters, insurance) with optional review-gating. A great model for replacing the stock pages with your own.
  - [patient-portal-forms](https://github.com/medical-software-foundation/canvas/tree/main/extensions/patient-portal-forms) — ships a whole forms experience as its own portal page: staff assign questionnaires (PHQ-9, GAD-7, ROS…) that patients complete in the portal, with responses posting back to the chart.
###  Missing something? Ask before you rebuild 
Customizing the portal puts you in the best position to see what's missing. If you hit something plugins can't do in the portal yet, requesting a **new SDK capability** is often a better move than jumping to building your own (Path 3) — it can unlock what you need _inside_ the built-in portal, so you keep everything Canvas handles for you (login, data, compliance) instead of rebuilding it. Many of today's patient-portal capabilities exist because customers asked for them.
> **Info:** Hitting the edge of what plugins can do in the portal? Tell your Canvas contact or Support what you're trying to build. A new SDK capability may unlock it inside the portal — and your request helps shape what we build next for everyone.
* * *
##  Path 3 — Build your own patient app on Canvas data 
If you want a fully branded app — your own UI, your own login — build it as an external application and use Canvas as the clinical source of truth. You move data between your app and Canvas in three **complementary** ways; most portals use a combination, because each fits a different job and has its own authentication model.
  - **[FHIR API](/api/)** and **[SimpleAPI](/sdk/handlers-simple-api-http/)** are calls _from your app into Canvas_ — **Canvas authenticates you**.
  - **[Events → webhooks](/sdk/events/)** are calls _from Canvas out to your app_ — **you authenticate Canvas**.
A typical combination:
  - **FHIR API** for the bulk of standard reads and writes (patients, appointments, conditions, coverage…).
  - **SimpleAPI** where you need something FHIR doesn't expose, a tailored/bundled response, or custom data — your app hits one plugin endpoint instead of stitching several calls.
  - **Events → webhooks** to keep your app in sync as things change in Canvas, instead of polling.
###  FHIR API — read & write standard Canvas data directly 
**Best for:** standard resources (Patient, Appointment, Condition, Coverage, etc.) read or written straight from your app.
**Auth (your app → Canvas):** Canvas issues OAuth2 tokens with SMART on FHIR scopes. For a portal where a patient logs in and must only see their **own** record, use a [patient-scoped token](/api/customer-authentication/#patient-scoped-tokens) — it's locked to a single patient and Canvas enforces it server-side, so any read or write touching another patient is rejected. See [Customer Authentication](/api/customer-authentication/) for the full flow, scopes, and the `user/` and `system/` contexts.
See the [FHIR API reference](/api/) and [Auth best practices](/api/authentication-best-practices/).
Examples:
  - [canvas_fhir_client](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/canvas_fhir_client) (SDK) — a Python client that authenticates and reads/writes Canvas FHIR resources.
  - [cms-access-fhir-client](https://github.com/medical-software-foundation/canvas/tree/main/extensions/cms-access-fhir-client) (MSF) — FHIR-client mechanics in action (OAuth plus a full request/response exchange), here integrating with the external CMS ACCESS FHIR APIs.
###  SimpleAPI — build the exact endpoints your app wishes Canvas had 
Where FHIR gives you standard resources, **SimpleAPI lets you define your own** — you own the URL, the request, and the JSON response shape, all running inside a Canvas plugin. Instead of bending your app to fit a generic API, you build the endpoint your app actually wants and call it directly.
_New to the idea? Read the announcement:[Introducing Custom API Endpoints with the Canvas SDK](https://www.canvasmedical.com/articles/introducing-custom-api-endpoints)._
This is where SimpleAPI shines:
  - **Shape the payload to your UI.** Return exactly the fields a screen needs, already assembled — no over-fetching, no reshaping FHIR bundles on the client.
  - **Collapse many calls into one.** Bundle related reads and writes into a single round-trip, so a screen that would take five FHIR calls takes one. Fewer requests, simpler client code, faster load.
  - **Reach data FHIR doesn't expose.** Surface your plugin's own [Custom Data](/sdk/custom-data/), computed values, or anything else in the [data module](/sdk/data/).
  - **Run your logic server-side, next to the data.** Validation, orchestration, and business rules live in the plugin — close to Canvas and behind your key — instead of scattered across your app.
Reads come from the [data module](/sdk/data/); writes go through [Effects](/sdk/effects/) and [Commands](/sdk/commands/) (the SDK data models are read-only).
**Auth (your app → Canvas):** an **API key** — declare a secret in the plugin and send it in the `Authorization` header (`APIKeyAuthMixin`). Simple, and the right choice for an external caller.
See [SimpleAPI HTTP handlers](/sdk/handlers-simple-api-http/).
SDK examples:
  - [api_samples](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/api_samples) — start here; the core request/response patterns.
  - [charting_api_examples](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/charting_api_examples) — endpoints that read and write chart data.
  - [note_management_app](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/note_management_app) — a fuller app built on SimpleAPI endpoints.
  - [custom_data_room_booking](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/custom_data_room_booking) — endpoints backed by Custom Data.
Real-world examples (MSF):
  - [lab-result-api](https://github.com/medical-software-foundation/canvas/tree/main/extensions/lab-result-api) — one `GET /lab-result/<id>` returns a lab report with its patient, originating order, ordering provider, and nested result values assembled into a single response. A textbook "collapse many calls into one, shaped to your UI" endpoint.
  - [cpt-billing-api](https://github.com/medical-software-foundation/canvas/tree/main/extensions/cpt-billing-api) — a write endpoint that adds CPT billing line items to a note from an external caller.
  - [note-command-api](https://github.com/medical-software-foundation/canvas/tree/main/extensions/note-command-api) — read notes with enhanced command data, and create notes via `POST /create-note` with flexible identifier lookup.
  - [custom-observation-management](https://github.com/medical-software-foundation/canvas/tree/main/extensions/custom-observation-management) — an API-key-authed read/write API over a clinical resource: `GET` a single observation, a filtered list, or the available filters, and `POST` to record a new one.
###  Events → webhooks — Canvas pushes changes to your app the moment they happen 
Instead of your app constantly polling Canvas asking "anything new?", **let Canvas tell you.** A plugin subscribes to the events you care about — an appointment booked, a task created, a patient updated — and POSTs to your endpoint the instant it happens.
Why reach for webhooks:
  - **Real-time sync, no polling.** Keep an external system current — a billing platform, a CRM, a data warehouse, your own app's database — the moment data changes, instead of nightly jobs that are always a little stale. For example, a patient gives the front desk an updated address; a webhook pushes that change to your app so it's already reflected the next time they log in to your portal.
  - **Trigger downstream workflows.** Fire an appointment reminder, page a care team, kick off a prior-auth, or open a ticket in your system as soon as the triggering event lands.
  - **Fan out from one event.** A single Canvas change can notify several systems at once, each with the payload it needs.
  - **Lower latency and load.** You react in seconds and skip the wasted requests — and the changes missed between polls — that polling brings.
**Auth (Canvas → your app — reversed):** **you** secure your receiving endpoint. The plugin sends a shared secret/signature (stored as a plugin secret) that your app verifies; no Canvas token is involved on the inbound call.
See the [SDK Events reference](/sdk/events/), the [HTTP Request effect](/sdk/effect-http-request/), and the [Creating Webhooks guide](/guides/creating-webhooks-with-the-canvas-sdk/).
SDK examples:
  - [example_patient_sync](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/example_patient_sync) — push patient changes to an external system on create/update.
  - [coverage_metadata_sync](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/coverage_metadata_sync) — sync coverage metadata when it changes.
Real-world examples (MSF):
  - [appointment-sync-webhook](https://github.com/medical-software-foundation/canvas/tree/main/extensions/appointment-sync-webhook) — POSTs appointment lifecycle events (created, cancelled, no-show) to an external system as they happen.
  - [task_webhook_notification](https://github.com/medical-software-foundation/canvas/tree/main/extensions/task_webhook_notification) — sends a customizable payload to your endpoint whenever a task is created or updated.
  - [gcal_sync](https://github.com/medical-software-foundation/canvas/tree/main/extensions/gcal_sync) — near-real-time two-way sync between Canvas appointments and Google Calendar, with Canvas as the system of record.

# Creating Webhooks With the Canvas SDK

Source: https://docs.canvasmedical.com/guides/creating-webhooks-with-the-canvas-sdk/

Webhooks are user-defined callbacks that make a request to an API. You may want to create a webhook to notify a system you control that some event has occurred in Canvas. This guide shows how to create a webhook that sends an API request containing the ID of a Task upon its creation.
> **Info:** This guide assumes pre-existing knowledge of the Canvas SDK. If you're starting from scratch, you may want to read and implement [Your First Plugin (with Claude Code)](/guides/your-first-plugin-with-claude-code/) before working through this exercise.
##  Initialize a new plugin 
The Canvas CLI gives you a great head start when creating a plugin. Simply run `canvas init`, and answer the prompt to name your plugin.
    ```sh
    $ canvas init
      [1/1] project_name (My Cool Plugin): Task Webhook
    Project created in /Users/andrew/src/canvas-plugins/task-webhook
    ```
This output shows the location of our freshly generated plugin.
##  Edit the plugin code 
The default content of this file shows you the information you have available to you in the comments. I've stripped it down to almost nothing so we can layer in the functionality step by step.
###  Log a message when a task is created. 
The code below listens for the `TASK_CREATED` event and logs the string "A Task was created!".
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    class Handler(BaseHandler):
        """
        When a task is created, log a message
        """
        RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
        def compute(self):
            """
            Log a message as tasks are created.
            """
            log.info("A Task was created!")
            return []
    ```
You can see this log output by first streaming logs with `canvas logs` and then creating a task. You can create this task with Canvas Chat, a Task Command, or our [FHIR Task Create endpoint](/api/task/#create).
After you've [installed your plugin](/sdk/canvas_cli/#canvas-install) and created a task, you should see this in your log stream:
    ```sh
    INFO 2024-09-26 17:04:08,396 Starting server, listening on port 50051
    INFO 2024-09-26 17:04:08,396 Loading custom-plugins/task_webhook
    INFO 2024-09-26 17:04:08,396 Loading plugin 'task_webhook:task_webhook.handlers.event_handlers:Handler'
    INFO 2024-09-26 17:04:24,410 A Task was created!
    INFO 2024-09-26 17:04:24,410 task_webhook:task_webhook.handlers.event_handlers:Handler.compute() completed (0 ms)
    INFO 2024-09-26 17:04:24,411 Responded to Event TASK_CREATED (1 ms)
    ```
Awesome! But we're not here to log, we need to make an API request. To do that, we need to use the HTTP client found in the Canvas SDK's [Utils module](/sdk/utils/)
###  Make an HTTP request when a Task is created 
We can use <https://webhook.site/> for a quick way to test our webhook and see the requests it receives. Here is the updated code that uses the HTTP client to make the request:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.utils import Http
    from logger import log
    class Handler(BaseHandler):
        """
        When a task is created, hit a webhook
        """
        RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
        def compute(self):
            """
            Notify our server of tasks as they are created.
            """
            url = "https://webhook.site/ee7aed78-b652-4d9e-b858-04465c409d15"
            payload = {
                "message": "A Task was created!"
            }
            http = Http()
            response = http.post(url, json=payload)
            if response.ok:
                log.info("Successfully notified API of task creation!")
            else:
                log.info("Notification unsuccessful. =[")
            return []
    ```
After you've [installed your updated plugin](/sdk/canvas_cli/#canvas-install) and created a task, you should see this in your log stream:
    ```sh
    INFO 2024-09-26 17:18:23,206 Loading custom-plugins/task_webhook
    INFO 2024-09-26 17:18:23,207 Reloading plugin 'task_webhook:task_webhook.handlers.event_handlers:Handler'
    INFO 2024-09-26 17:18:33,850 Successfully notified API of task creation!
    INFO 2024-09-26 17:18:33,851 task_webhook:task_webhook.handlers.event_handlers:Handler.compute() completed (693 ms)
    INFO 2024-09-26 17:18:33,851 Responded to Event TASK_CREATED (696 ms)
    ```
This log output is a great reminder for me to mention that making HTTP requests to external servers will slow plugin execution while it waits on the external server to respond. It's a good idea to make sure the servers you're hitting have a sufficiently quick response time.
Checking in on our webhook.site logs shows it received our request! ![Log of web
request](/assets/images/webhook-guide/webhook-guide-first-request.png)
Awesome, but you aren't sending these requests to a server that allows unauthenticated requests! And this request doesn't even tell you anything about the task it's notifying you about. This isn't useful at all!
Let's do another iteration, this time using the information provided along with the event so that we can send a usable message, securely. We're specifically going to incorporate the event's `target` and `secrets`.
###  Make an authenticated HTTP request that includes the newly created Task's ID 
Within your `Handler` class, you have access to `self.target`, which represents the ID of the subject of the event. In our case, it will be the Task's ID. This is the same ID used in the [FHIR Task endpoints](/api/task/), so you can use it to make FHIR API requests.
You also have access to `self.secrets`, which is a python dictionary containing the key-value pairs from your plugins configuration page. You declare the keys in your `CANVAS_MANIFEST.json`, and can then set the values after the plugin is installed.
We'll set two secrets, one for the unique id of the webhook, and one for an auth token. Here's what the manifest file looks like with secrets declared:
    ```json
    {
        "sdk_version": "0.1.4",
        "plugin_version": "0.0.1",
        "name": "task_webhook",
        "description": "Webhooks for task creation",
        "components": {
            "handlers": [
                {
                    "class": "task_webhook.handlers.event_handlers:Handler",
                    "description": "Hit an API when a task is created",
                    "data_access": {
                        "event": "",
                        "read": [],
                        "write": []
                    }
                }
           ]
        },
        "variables": [
            {"name": "WEBHOOK_ID", "sensitive": true},
            {"name": "AUTH_TOKEN", "sensitive": true}
        ],
        "tags": {},
        "license": "",
        "readme": "./README.md"
    }
    ```
The `variables` array declares two sensitive variables, `WEBHOOK_ID` and `AUTH_TOKEN`. After we update the plugin, we can set values for these in the plugin configuration page. This allows for different values to be used across different installations. Marking each entry with `"sensitive": true` means the values will be masked in the Admin UI and listed only as `[set]` or `[not set]` by `canvas config list`.
Here's how that configuration looks:
![Plugin secrets
configuration](/assets/images/webhook-guide/webhook-guide-secrets.png)
With those values set, we can use them in our code:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.utils import Http
    from logger import log
    class Handler(BaseHandler):
        """
        When a task is created, hit a webhook
        """
        RESPONDS_TO = EventType.Name(EventType.TASK_CREATED)
        def compute(self):
            """
            Notify our server of tasks as they are created.
            """
            url = f"https://webhook.site/{self.secrets['WEBHOOK_ID']}"
            headers = {
                "Authorization": f"Bearer {self.secrets['AUTH_TOKEN']}"
            }
            payload = {
                "message": "A Task was created!",
                "resource_id": self.target
            }
            http = Http()
            response = http.post(url, json=payload, headers=headers)
            if response.ok:
                log.info("Successfully notified API of task creation!")
            else:
                log.info("Notification unsuccessful. =[")
            return []
    ```
And checking once more on our webhook.site logs shows it received our updated request, including our `AUTH_TOKEN` value and the created task's ID.

request](/assets/images/webhook-guide/webhook-guide-second-request.png)
##  Listening for multiple events 
A single plugin handler can listen for multiple event types. The event type will be available in `self.event.type`, which will contain a member of the `EventType` enum. The [full list of events is available](/sdk/events/#event-types-and-context). Here is a short example that listens for two different events:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.utils import Http
    from logger import log
    class Handler(BaseHandler):
        """
        When a task is created or updated, hit a webhook
        """
        RESPONDS_TO = [
            EventType.Name(EventType.TASK_CREATED),
            EventType.Name(EventType.TASK_UPDATED),
        ]
        def compute(self):
            """
            Notify our server of tasks as they are created.
            """
            url = f"https://webhook.site/{self.secrets['WEBHOOK_ID']}"
            headers = {"Authorization": f"Bearer {self.secrets['AUTH_TOKEN']}"}
            # self.event.type is a member of the EventType enum corresponding to
            # one of the event types in the handler's RESPONDS_TO attribute
            verb = 'created' if self.event.type == EventType.TASK_CREATED else 'updated'
            payload = {
                "message": f"A Task was {verb}!",
                "resource_id": self.target,
            }
            http = Http()
            response = http.post(url, json=payload, headers=headers)
            # You can also get the name of the event as as string using EventType.Name()
            event_name = EventType.Name(self.event.type)
            if response.ok:
                log.info(f"Successfully notified API of {event_name}")
            else:
                log.info(f"Notification of {event_name} unsuccessful. =[")
            return []
    ```
Alternatively, you could include several classes, each resposible for some specific request type. When including several classes in one plugin, they all have access to the same secrets dictionary, you just need to declare each class in the manifest file.
##  Conclusion 
I hope you found this helpful. Happy coding, we can't wait to see what you build!

# Building a Custom Portal Landing Page

Source: https://docs.canvasmedical.com/guides/custom-landing-page/

This guide provides examples of how to leverage patient data to personalize the portal landing page, and explains how to integrate the ready-made widgets provided by Canvas.
> **Info:** This guide assumes pre-existing knowledge of the Canvas SDK. If you're starting from scratch, you may want to read and implement [Your First Plugin (with Claude Code)](/guides/your-first-plugin-with-claude-code/) before working through this exercise.
##  What Are Widgets in the Patient Portal? 
[Widgets](/sdk/patient-portal/#portal-landing-page-widgets) in the patient portal are interactive components that enhance the user experience by providing quick access to information and functionalities. They can display key details like upcoming appointments. Widgets can be fully customized with unique content or leverage ready-made components—such as Appointments and Messaging provided by Canvas to ensure consistency and ease of use. These widgets are organized on the landing page using a grid layout, which supports various sizes to optimize the visual presentation and responsiveness across different devices.
##  How to add a Widget? 
A widget can be added by listening to the `PATIENT_PORTAL__WIDGET_CONFIGURATION` event and returning one or several `PortalWidget`
###  Step 1: Initialize a plugin 
The Canvas CLI gives you a great head start when creating a plugin. Simply run
    ```bash
      canvas init
    ```
Then, follow the prompts to name and configure your new plugin project.
###  Step 2: Update your handler 
Modify your handler to handle the widget configuration event. For example:
    ```python
    from canvas_sdk.effects.widgets import PortalWidget
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__WIDGET_CONFIGURATION)
        def compute(self):
            widget = PortalWidget(
              content="Hello World",
              size=PortalWidget.Size.COMPACT,
              priority=10
            )
            return [widget.apply()]
    ```
This code listens for the `PATIENT_PORTAL__WIDGET_CONFIGURATION` event and, when triggered, creates a new widget with a simple "Hello World" message, a compact size, and a priority of 10.
##  Patient medication widget 
This widget will show the last medication and CTA to request a refill.
So let's update the example above to:
  - Fetch the patient's medication.
  - Leverage [HTML templating](/sdk/layout-effect/#custom-html-and-django-templates) to display the necessary information
###  Step 1: Fetch patient medication 
Since the event includes the patient object, you can easily access all the necessary data. Add the following snippet to your compute method to retrieve the patient's details:
    ```python
    patient = Patient.objects.get(id=self.target)
    last_medication = patient.medications.last()
    ```
###  Step 2: Prepare HTML template 
Create a `templates` folder inside your plugin's folder:
    ```bash
      mkdir templates
    ```
Add the HTML file:
    ```bash
      touch medication_widget.html
    ```
And add the following HTML:
    ```html
    <!DOCTYPE html>
    <html lang="en">
    <head>
      <meta charset="UTF-8">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <style>
        body, html {
          height: 100%;
          width: 100%;
          margin: 0;
          font-family: "Roboto","Helvetica","Arial",sans-serif;
          font-size: 16px;
        }
      </style>
    </head>
    <body>
    </body>
    </html>
    ```
###  Step 3: Design your widget 
> **Info:** Developers are responsible for providing all the necessary CSS to style their widget. The widget does not include default styles, so you should include custom CSS—either inline or via an external stylesheet—to define the layout, typography, colors, spacing, and interactive elements.
While you can design your widget in any way that suits your needs, for this example we'll create one featuring a header and a card component. The card will display the medication name, the prescription date, and a clear call-to-action (CTA) button that redirects the patient to the messaging page to request a refill.
####  Header 
A light gray background color and a blue text to ensure it matches the patient portal aesthetic.
    ```html
    <style>
      .header {
          padding: 8px;
          background: #E5E5E5;
          color: #2185D0;
          text-align: left;
          margin: 0;
          font-weight: 500;
          font-size: 18px;
          line-height: 1.6;
        }
    </style>
    <body>
        <div class="header">My Health</div>
    </body>
    ```
####  Card Component 
We will add template variables for the medication name and start date, allowing these values to be dynamically updated in the plugin.
    ```html
    <body>
      <div class="widget">
        <div class="medication-info">
          <span class="material-icons">medication</span>
          <span>{{name}}</span>
        </div>
        <p style="padding: 0 12px">This medication was prescribed on {{start_date}}. Do you need a refill?</p>
        <button onclick="onClick()">Ask for a refill</button>
      </div>
      <script>
        function onClick() {
          window.top.location.href = "http://localhost:8000/app/messaging"
        }
      </script>
    </body>
    ```
Let's dive in and add some styles to the card.
Our `widget` class ensures that all elements are both vertically and horizontally centered, creating a sleek card design with rounded borders and a subtle shadow for a modern, elevated look.
    ```css
    .widget {
      display: flex;
      flex-direction: column;
      justify-content: center;
      align-items: center;
      width: 98%;
      height: 80%;
      border-radius: 4px;
      box-shadow: 0 2px 1px -1px rgba(0, 0, 0, 0.2), 0 1px 1px 0 rgba(0, 0, 0, 0.14), 0 1px 3px 0 rgba(0, 0, 0, 0.12);
      background-color: #f9f9f9;
      text-align: center;
      margin: 4px auto auto;
    }
    ```
Our medication info section will feature a Material UI icon next to the medication name, providing a clear and modern visual representation consistent with the portal's design aesthetic.
    ```css
    .medication-info {
      display: flex;
      align-items: center;
      gap: 10px;
      margin-bottom: 15px;
      padding: 0 8px;
      font-size: 14px;
    }
    .material-icons {
      font-size: 50px;
    }
    ```
And finally, we style the CTA button to mimic a Material UI button, ensuring it aligns perfectly with the portal's overall design aesthetic.
    ```css
    button {
      margin-top: 16px;
      background-color: #1976d2;
      color: #fff;
      border: none;
      border-radius: 4px;
      padding: 16px 16px;
      font-size: 14px;
      min-width: 64px;
      text-transform: uppercase;
      box-shadow: 0 3px 1px -2px rgba(0,0,0,0.2),
                  0 2px 2px 0 rgba(0,0,0,0.14),
                  0 1px 5px 0 rgba(0,0,0,0.12);
      cursor: pointer;
      transition: background-color 0.3s ease;
    }
    button:hover {
      background-color: #115293;
    }
    ```
###  Step 4: Tying everything together 
Update your plugin's `compute` method to pass the desired values for medication name and start date using `render_to_string` function
    ```python
    medication_info = {
        "start_date": last_medication.start_date.strftime("%B %d, %Y"),
        "name": last_medication.codings.first().display
    }
    widget = PortalWidget(content=render_to_string("templates/medication_widget.html", medication_info), size=PortalWidget.Size.COMPACT, priority=10)
    ```
![medication widget](/assets/images/sdk/widgets/patient_medication_widget.png)
###  Full Example 
    ```python
    from canvas_sdk.effects.widgets import PortalWidget
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Patient
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__WIDGET_CONFIGURATION)
        def compute(self):
            patient = Patient.objects.get(id=self.target)
            last_medication = patient.medications.last()
            medication_info = {
                "start_date": last_medication.start_date.strftime("%B %d, %Y"),
                "name": last_medication.codings.first().display
            }
            medication_widget = PortalWidget(
              content=render_to_string("templates/medication_widget.html", medication_info),
              size=PortalWidget.Size.COMPACT,
              priority=10
            )
            return [medication_widget.apply()]
    ```

##  Upcoming appointments Widget provided by Canvas 
This is one of the ready-made widgets provided by Canvas that you can add to your patient portal. It will show upcoming appointments.
###  Step 1: Add a new handler to your plugin 
Create a new handler in your plugin with the following content:
    ```python
    from canvas_sdk.effects.widgets import PortalWidget
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class UpcomingAppointmentWidget(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_PORTAL__WIDGET_CONFIGURATION)
        def compute(self):
            widget = PortalWidget(component=PortalWidget.Component.APPOINTMENTS, priority=25)
            return [widget.apply()]
    ```

# Customize your panel buttons

Source: https://docs.canvasmedical.com/guides/customize-panel-buttons/

This guide is intended to help you customize which buttons are shown on the main page and the patient page. It allows you to add, order, or hide specific buttons as needed.
##  Getting Started 
To achieve this, you'll use the [PANEL_SECTIONS_CONFIGURATION](/sdk/events) event, which sends both the patient and the user attributes.
If you need to identify where the event is coming from, you can check if the patient attributes are present — on the global (main) page, the patient will be empty.
##  Defining the Sections 
In the SDK, you'll use the [PanelConfiguration](/sdk/layout-effect/#panel-configuration) effect. This effect takes in the sections you want to display and specifies the page where they should appear.
You'll use:
  - PanelPatientSection – for sections shown on the patient page
  - PanelGlobalSection – for sections shown on the main (global) page
The SDK has built-in safeguards to prevent you from mixing them up or placing a section on the wrong page.
That's It!
Once you apply the effect, your panel is configured — go check your page to see the changes in action!
##  The Complete Example 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.panel_configuration import PanelConfiguration
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class CustomizePatientSection(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PANEL_SECTIONS_CONFIGURATION)
        def compute(self) -> list[Effect]:
            patient = self.target
            # user = self.context["user"]
            if patient:
                return [PanelConfiguration(sections=[
                    PanelConfiguration.PanelPatientSection.REFILL_REQUEST,
                    PanelConfiguration.PanelPatientSection.LAB_REPORT,
                    PanelConfiguration.PanelPatientSection.CHANGE_REQUEST,
                    PanelConfiguration.PanelPatientSection.TASK,
                ], page=PanelConfiguration.Page.PATIENT if patient else PanelConfiguration.Page.GLOBAL).apply()]
            else:
                return []
    class CustomizeGlobalSection(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PANEL_SECTIONS_CONFIGURATION)
        def compute(self) -> list[Effect]:
            patient = self.target
            # user = self.context["user"]
            if not patient:
                return [PanelConfiguration(sections=[
                    PanelConfiguration.PanelGlobalSection.LAB_REPORT,
                    PanelConfiguration.PanelGlobalSection.TASK,
                    PanelConfiguration.PanelGlobalSection.CHANGE_REQUEST,
                ], page=PanelConfiguration.Page.PATIENT if patient else PanelConfiguration.Page.GLOBAL).apply()]
            else:
                return []
    ```

# Customize Search Results

Source: https://docs.canvasmedical.com/guides/customize-search-results/

In a typical visit note, it's common for clinicians to make 20, 30, even 50 or more selections from structured terminologies with commands like Diagnose, Prescribe, Family History, and many more. You can help clinicians make faster and more accurate selections with Canvas plugins. Write simple plugin code to apply custom filtering, sorting, and search result annotations in real time with near zero latency.
This search modification can help clinicians:
  - Choose the most appropriate medication that is also covered by insurance
  - Prioritize in-network specialists
  - Consider appropriate risk adjustment factors when selecting diagnosis codes
Canvas supports modifying search results in [all refactored commands](/product-updates/commands-module/#progress).
First, we'll show you a complete example of customizing the search results for choosing a medication in a Medication Statement command, then we'll break it down piece by piece so you can adapt the example to your own needs.
##  The Complete Example 
This example checks for the presence of a particular medication in the search results and, if present, annotates that medication option with additional information and adjusts its position to the top of the search results.
For reference, here's the difference in behavior with the plugin inactive vs active:
**Inactive (normal behavior):**
![With the plugin inactive, the results are unaltered](/assets/images/customize-search-results/plugin-inactive.png)
**Active (modified behavior):**
![With the plugin active, the preferred result is listed first, and with additional context](/assets/images/customize-search-results/plugin-active.png)
Here's the code in its entirety:
    ```python
    import json
    from canvas_sdk.events import EventType
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.handlers import BaseHandler
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.MEDICATION_STATEMENT__MEDICATION__POST_SEARCH)
        def compute(self):
            results = self.context.get("results")
            if results is None:
                return [Effect(type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS, payload=json.dumps(None))]
            post_processed_results = []
            for result in results:
                should_float_to_top = False
                for coding in result.get("extra", {}).get("coding", []):
                    if (
                        coding.get("code") == 554704
                        and coding.get("system") == "http://www.fdbhealth.com/"
                    ):
                        if result.get("annotations") is None:
                            result["annotations"] = []
                        result["annotations"].append("Kirkland Signature")
                        should_float_to_top = True
                if should_float_to_top:
                    post_processed_results.insert(0, result)
                else:
                    post_processed_results.append(result)
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(post_processed_results),
                )
            ]
    ```
##  Anatomy of the Example 
This code can be broken down into the following sections:
  - Register interest in the correct search event
  - Decide whether to make any changes
  - Loop through the results, making modifications as appropriate
  - Return the modified results as a properly typed effect
###  Register interest in the correct search event 
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.MEDICATION_STATEMENT__MEDICATION__POST_SEARCH)
        def compute(self):
            results = self.context.get("results")
    ```
The class inherits from `BaseHandler`, which clues the plugin-runner into registering your code as interested in the event or events listed in the `RESPONDS_TO` class constant. We only specify one event here, `MEDICATION_STATEMENT__MEDICATION__POST_SEARCH`, but you could make this value a list to fire on multiple events. The event we've chosen to listen for can be read backwards to understand when it fires. This event is emitted after (" _post_ ") the normal _search_ results are found for the _medication_ autocomplete field of the _medication statement_ command. This event comes with a context that contains the search results that would be served to the user if there were no modifications.
###  Decide whether to make any changes 
    ```python
            if results is None:
                return [Effect(type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS, payload=json.dumps(None))]
    ```
If the value of the results `is None`, we bail out early. There is a subtle difference between results of `None` and an empty result set (`[]`). Results being `None` means "make no changes, present the results without modification", whereas an empty result set means "present no options to the user".
###  Loop through the results, making modifications as appropriate 
    ```python
            post_processed_results = []
            for result in results:
                should_float_to_top = False
                for coding in result.get("extra", {}).get("coding", []):
                    if (
                        coding.get("code") == 554704
                        and coding.get("system") == "http://www.fdbhealth.com/"
                    ):
                        if result.get("annotations") is None:
                            result["annotations"] = []
                        result["annotations"].append("Kirkland Signature")
                        should_float_to_top = True
                if should_float_to_top:
                    post_processed_results.insert(0, result)
                else:
                    post_processed_results.append(result)
    ```
In this block of code, we create a new list named `post_processed_results` to hold our modified result set. We then loop through each result in the unmodified results set, and check to see if the current medication result matches our chosen criteria (FDB code 554704).
If it does match, we first check to see if any annotations already exist and initialize the annotations list if needed. We then append our chosen annotation to the result's annotation list and flag it as needing to be floated to the top (we had defaulted it to not be floated earlier on).
Finally, we add the result to our parallel list, `post_processed_results`. If it matched and was marked as being floated to the top, we insert it into the list at position 0. If it did not match, we append the result to the end of the list.
###  Return the modified results as a properly typed effect 
    ```python
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(post_processed_results),
                )
            ]
    ```
With our list of modified results in place, we just need to return an effect of type `AUTOCOMPLETE_SEARCH_RESULTS` with our modified list as the payload.
The dropdown of options presented to the user now reflects our modifications!
##  Understanding Search Result Data Structures 
The search results in this example follow the MedicationSearchResult structure. Each result contains fields like `text`, `disabled`, `description`, `annotations`, `extra`, and `value` that provide detailed information about the medication option.
For complete details about medication search result data contracts and other search result structures, see the [Search Result Data Structures](/sdk/events/#search-result-data-structures) section in the Events documentation.
##  Offering your own providers alongside the directory 
The four provider-search surfaces — Refer, Imaging Order, fax recipient, and a patient's external care team — search the shared contact directory by default. Providers you create with the [ServiceProvider effect](/sdk/effect-service-provider/) are not searched automatically, so if you maintain your own directory you have to offer them yourself.
The pattern is the same on all four surfaces: query your own [ServiceProvider](/sdk/data-serviceprovider/) records, put them ahead of the directory's results, and return the combined list.
**Use the POST_SEARCH event, not PRE_SEARCH.** Only the post-search context carries what the directory returned, in `context["results"]`. On a pre-search that list is empty, so there is nothing to merge with — and on a command pre-search any `AUTOCOMPLETE_SEARCH_RESULTS` effect you return is authoritative, which means an empty reply blanks the dropdown instead of leaving it alone.
Which helper you call depends on the surface:
Surface| Event| Helper  
---|---|---  
Refer| `REFER__REFER_TO__POST_SEARCH`| `as_search_result()`  
Imaging Order| `IMAGING_ORDER__IMAGING_CENTER__POST_SEARCH`| `as_search_result()`  
Fax recipient| `FAX__RECIPIENT__POST_SEARCH`| `as_search_contact()`  
External care team| `PATIENT_PROFILE__EXTERNAL_CARE_TEAM__POST_SEARCH`| `as_search_contact()`  
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import ServiceProvider
    # Cap the query so a loose search term cannot pull your whole table into the sandbox.
    MAX_LOCAL_PROVIDERS = 200
    # The sandbox has no Q objects, so each field is queried separately and unioned in Python.
    SEARCHABLE_FIELDS = ("first_name", "last_name", "practice_name", "specialty")
    def matching_providers(search_term):
        matches = {}
        for field in SEARCHABLE_FIELDS:
            providers = ServiceProvider.objects.filter(
                is_active=True, **{f"{field}__icontains": search_term}
            )[:MAX_LOCAL_PROVIDERS]
            for provider in providers:
                matches.setdefault(provider.dbid, provider)
        return list(matches.values())[:MAX_LOCAL_PROVIDERS]
    class ContactDirectorySearch(BaseHandler):
        """Offer our own providers above the directory's on the fax and care team searches."""
        RESPONDS_TO = [
            EventType.Name(EventType.FAX__RECIPIENT__POST_SEARCH),
            EventType.Name(EventType.PATIENT_PROFILE__EXTERNAL_CARE_TEAM__POST_SEARCH),
        ]
        def compute(self):
            search_term = str(self.event.context.get("search_term") or "").strip()
            if not search_term:
                # An empty term must not push the entire local directory into the dropdown.
                return self.no_opinion()
            matches = matching_providers(search_term)
            if not matches:
                return self.no_opinion()
            ours = [
                provider.as_search_contact(["Our directory"])
                for provider in matches
            ]
            # Keep the directory's results underneath, minus anyone we already offered.
            superseded = {provider.full_name.lower() for provider in matches}
            theirs = [
                result
                for result in (self.event.context.get("results") or [])
                if f"{result.get('firstName') or ''} {result.get('lastName') or ''}".strip().lower()
                not in superseded
            ]
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(ours + theirs),
                )
            ]
        def no_opinion(self):
            """A null payload means "keep whatever the search already found"."""
            return [
                Effect(type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS, payload=json.dumps(None))
            ]
    ```
For Refer and Imaging Order, subscribe to those two events instead and swap `as_search_contact()` for `as_search_result()`. The merge is the same, except the directory's results carry their display name in `text` rather than in `firstName` / `lastName`.
A few things worth carrying over into your own version:
  - **Filter to`is_active=True`.** Deactivating a provider is how a customer retires it, so offering a deactivated one invites picking it again.
  - **Return a null payload when you have nothing to add** , rather than an empty list. On the contact surfaces an empty list clears the results.
  - **Prefer your own record when it duplicates a directory contact.** Selecting your record threads its `service_provider_id` through to the commit, so the existing row is reused instead of a near-duplicate being written. Match conservatively — listing a provider twice is a smaller failure than hiding one.
  - **Annotate what you add** so the user can tell your entries from the directory's.
##  Accessing User Context 
PRE_SEARCH and POST_SEARCH events include information about the user performing the search in the event context. This includes search events for command fields like prescriber, medication, diagnosis, pharmacy, and many others. It also includes the non-command fax recipient and external care team directory searches listed under [Other Events](/sdk/events/#other-events). All of these searches can be customized the same way.
You can access the user's staff id from the context:
    ```python
    def compute(self):
        user_context = self.context.get("user", {})
        staff_key = user_context.get("staff")
        # Use the staff id to customize search results
        # based on the user's role, preferences, or permissions
    ```
This can be useful for customizing search results based on:
  - User-specific preferences or settings
  - Role-based filtering (e.g., showing different prescriber options based on the user's specialty)
  - Permission-based access control
  - User's organization or practice location

# Embedding a SMART app into Canvas

Source: https://docs.canvasmedical.com/guides/embedding-a-smart-on-fhir-application/

Canvas' FHIR API supports the SMART launch sequence, and the Canvas SDK allows you to embed html content within the Canvas EMR. The combination of these capabilities is a frictionless experience when embedding a SMART app into Canvas. This example will show you how to register a SMART app's credentials and create an application to launch it from within a patient's chart.
##  In this guide you will learn how to: 
  - Configure credentials for a public OAuth application.
  - Create an application to initiate the SMART launch sequence.
  - Use application launch context to help form the SMART launch URL parameters.
##  What is a SMART app? 
SMART on FHIR applications adhere to a standards-based approach to authentication, authorization, and data access with the goal of being portable across EMR installations and vendors. Because SMART apps limit themselves to standards based data, the logic can be agnostic to the EMR it is running against. Vendor to vendor, site to site, FHIR is FHIR, that's how it works, right?
##  Where can I get a SMART app? 
We've provided an example SMART app [here](https://github.com/canvas-medical/example-smart-on-fhir-app). You can fork it and customize, or just use ours as-is. We use GitHub pages to host it at `https://canvas-medical.github.io/example-smart-on-fhir-app/`. Please ensure the client id [listed in `launch.html`](https://github.com/canvas-medical/example-smart-on-fhir-app/blob/205b14ed8d4f4d9c57fd11a26f9a22c800f38c29/launch.html#L15) matches the client id for the credentials you configure in the next step.
##  Configuring credentials 
The first step to embedding a SMART application is to configure OAuth credentials for it to use. Navigate to `<YOUR_CANVAS_URL>/auth/applications/register/` and choose `Public` client type, `Authorization code` grant type, the `RSA` algorithm, and set the redirect uri for your SMART application.
![OAuth Configuration](/assets/images/guides/embedding-a-smart-app/SMART_OAuth.png)
##  Creating an application 
We encourage you to read our more comprehensive guide on [creating applications via the Canvas SDK](/guides/your-first-application/), but we can provide an abridged version here.
Using the [Canvas CLI](/sdk/canvas_cli/), create an application from a template using `canvas init application`. After providing a name, the Canvas CLI will create a directory with your application inside it.
    ```bash
    dev@canvas:plugins$ canvas init application
      [1/1] project_name (My Cool Application): My Smart App
    Project created in /Users/dev/src/plugins/my_smart_app
    dev@canvas:plugins$ tree my_smart_app/
    my_smart_app/
    ├── CANVAS_MANIFEST.json
    ├── README.md
    ├── applications
    │   ├── __init__.py
    │   └── my_application.py
    └── assets
        └── python-logo.png
    3 directories, 5 files
    ```
There are two files we'll want to visit for changes: `CANVAS_MANIFEST.json` and `applications/my_application.py`.
###  Configuring the manifest file 
In order to set the same-origin policy for the iframe our SMART app will be embedded into, we need to make sure the url where the SMART app is hosted is listed in the `url_permissions` section of the manifest, and the `ALLOW_SAME_ORIGIN` permission is requested.
    ```json
        "url_permissions": [
            {
                "url": "https://canvas-medical.github.io",
                "permissions": ["ALLOW_SAME_ORIGIN"]
            }
        ],
    ```
We also want to change the application scope from the default "global" setting to "patient specific":
    ```json
        "components": {
            "applications": [
                {
                    ...
                    "scope": "patient_specific",
                }
            ],
        },
    ```
###  Setting the SMART launch URL 
The SMART authorization dance begins with the SMART app's launch URL. The parameters present on this URL set the wheels in motion. The launch URL is loaded in an iframe, and javascript immediately reads the `iss` param in order to probe the FHIR API's CapabilityStatement for the EMR's Authorize endpoint, which the iframe is then redirected to, with its own load of URL parameters in tow.
We can set this initial URL and launch params in the `on_open` method found in `applications/my_application.py`. This is the code that is invoked when a user clicks the application's launch icon.
    ```python
    import json
    from base64 import b64encode
    from urllib.parse import urlencode
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class MyApplication(Application):
        def on_open(self) -> Effect:
            launch_context = {
                "patient": self.context["patient"]["id"]
            }
            encoded_launch_context = b64encode(json.dumps(launch_context).encode()).decode()
            launch_params = {
                "iss": f"https://fumage-{self.environment['CUSTOMER_IDENTIFIER']}.canvasmedical.com",
                "launch": encoded_launch_context
            }
            encoded_launch_params = urlencode(launch_params)
            return LaunchModalEffect(
                url=f"https://canvas-medical.github.io/example-smart-on-fhir-app/launch.html?{encoded_launch_params}",
                target=LaunchModalEffect.TargetType.RIGHT_CHART_PANE,
            ).apply()
    ```
That's all the plugin work we need to do in order to create a launcher for the SMART application. Install the plugin into your Canvas instance, navigate to a patient's chart, and choose your application from the launcher.
##  Executing the launch sequence 
Upon launching your application, the SMART app will need the user to sign off on the access token it will receive to access the FHIR API on behalf of the logged in user.
![Authorize the token](/assets/images/guides/embedding-a-smart-app/SMART_Authorize.png)
The page you're seeing in the image is served by Canvas. This page is asking for the logged in user's consent to sending the SMART app a token which can access the FHIR API on the user's behalf. Clicking `Authorize` will redirect the iframe to the URL specified in the OAuth client's configuration with several params, most critically the API access token.
With the SMART app now in possession of a valid API access token, the application can function with access to all the data it is authorized to retrieve from the FHIR API. The example SMART app we've been working with simply shows the raw FHIR records retrieved for the patient.
![SMART app in action](/assets/images/guides/embedding-a-smart-app/SMART_App.png)
If you want to update the example SMART app to authorize additional data access from the FHIR API, you'll need to add those endpoints to the `scope` values in [launch.html](https://github.com/canvas-medical/example-smart-on-fhir-app/blob/main/launch.html), or wherever your authorize method is called:
    ```html
        <script>
            FHIR.oauth2.authorize({
                ...
                // The scopes that you request from the EHR. In this case we want to:
                scope: "patient/Patient.read patient/MedicationStatement.read patient/Goal.read patient/DocumentReference.read launch offline_access openid fhirUser",
                ...
            });
        </script>
    ```
For a more comprehensive list of available FHIR scopes, visit the [API docs](https://docs.canvasmedical.com/api/).
##  A more flexible alternative 
If you're looking to provide your users a more native experience without requiring the intricate authorization dance SMART prescribes, you're already pretty close just by going through the exercise above! While we created an embedded iframe of remote-hosted content, the Canvas SDK also allows you to [define HTTP endpoints](/sdk/handlers-simple-api-http/) which can also be the targets of the iframes. This allows your plugins to host [dynamically rendered HTML](/sdk/layout-effect/#custom-html-and-django-templates), CSS, Javascript, and more, with no external hosting required! You can take advantage of the built-in [session authentication](/sdk/handlers-simple-api-http/#session) for access control (no separate logins or authorizations for your users), and you have direct access to the EMR database through the Canvas SDK's [data module](/sdk/data/). [Caching](/sdk/caching/) and [websockets](/sdk/handlers-simple-api-websocket/) help you provide modern experiences, while the [effects module](/sdk/effects/) ensures you can write new data back into Canvas as needed.
The Canvas SDK allows you to deploy full web applications within the EMR, colocating your code with the data it needs to function, and without requiring any additional infrastructure.

# Visualizing Data Within the Canvas Chart

Source: https://docs.canvasmedical.com/guides/growth-charts/

The Canvas SDK gives you access to real-time patient data and allows you to create custom UIs accessible from a patient's chart. The combination of these capabilities allows you to create rich, interactive data visualizations your clinicians can access directly in the charting interface. This example will show you how we've used this approach to implement a pediatric growth charts feature.
##  In this guide you will learn how to: 
  - Use the [`ActionButton`](/sdk/handlers-action-buttons) handler to provide a button, specify its location, and define its action in the UI.
  - Use the [`LaunchModalEffect`](/sdk/layout-effect/#modals) to display your custom visualization.
  - Fetch patient [observations](/sdk/data-observation/), such as height and weight, from the [data module](/sdk/data/).
  - Use the patient observation data within an HTML template.
  - Combine all of the above to surface a pediatric growth chart visualization right in the chart.
##  Growth Charts 
Growth charts are percentile curves showing the distribution of selected body measurements in children. A growth chart shows how a child's height, weight, and head circumference (for infants) compare to other children of the same age and sex. It helps track a child's growth over time and can indicate whether they are growing at an expected rate. Growth charts are commonly used by doctors to monitor development and identify potential health concerns. In this guide we will use charts from the [Center for Disease Control and Prevention (CDC)](https://www.cdc.gov/growthcharts/who-data-files.htm) to demonstrate how you can create your own.
The complete plugin is open-source and can be found in the [Medical Software Foundation GitHub repo](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/growth_charts/).
The plugin adds a button on the Vital Signs section of the patient chart that, when clicked, launches a modal displaying the patient's height, weight, and head circumference measurements graphed against various percentile curves.
![vitals action button](/assets/images/vitals-action-button.png)
![chart template](/assets/images/growth-charts.png)
In the following steps, we'll show you how we used the Canvas SDK to create it.
##  Adding a button 
To add a button to the vital signs section, you'll implement an [`ActionButton`](/sdk/handlers-action-buttons) handler. In your handler class, you'll set the `BUTTON_LOCATION` constant to `ActionButton.ButtonLocation.CHART_SUMMARY_VITALS_SECTION` to make the action button appear in the corresponding summary section of the chart.
    ```python
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.effects import Effect
    class GenerateVitalsGraphs(ActionButton):
        BUTTON_TITLE = "Growth Charts"
        BUTTON_KEY = "show_growth_charts"
        BUTTON_LOCATION = ActionButton.ButtonLocation.CHART_SUMMARY_VITALS_SECTION
        def handle(self) -> list[Effect]:
            # This method is invoked when the button is clicked.
            pass
    ```
##  Launching a modal when the button is clicked 
Now that you have your button showing in the chart section, you can launch a modal when it's clicked using the [`LaunchModalEffect`](/sdk/layout-effect/#modals)
In this guide, we are launching a modal, but this click action can result in any [effect](/sdk/effects/) your handling code returns.
Here's an example of a simple plugin using the `LaunchModalEffect` to display a "Hello World" message.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.action_button import ActionButton
    from canvas_sdk.templates import render_to_string
    class HelloWorld(ActionButton):
        BUTTON_TITLE = "Hello World"
        BUTTON_KEY = "show_hello_world"
        BUTTON_LOCATION = ActionButton.ButtonLocation.NOTE_HEADER
        def handle(self) -> list[Effect]:
            launch_modal = LaunchModalEffect(content=render_to_string("templates/hello-world.html", { "title": "hello world" }))
            return [launch_modal.apply()]
    ```
And here's the result!
![action button](/assets/images/action-button-hello-world.png)
![hello world](/assets/images/template-hello-world.png)
##  Using HTML templates in the modal 
The use of templates allows us to render any kind of information from the data we have. We can even import external libraries from CDNs and add CSS styles to customize and enhance our modal.
To draw our graphs we use d3js, a free, open-source JavaScript library for visualizing data. How to use d3js is outside the scope of this guide, but you can find great documentation and tutorials on the d3 website [here](https://d3js.org/getting-started)
Here's an example of a template file name `hello-world.html` that receives a variable called title, which will be used inside the template.
    ```html
    <!DOCTYPE html>
    <style>
        body {
            font-family: Arial, sans-serif;
            font-size: 30px;
        }
    </style>
    <script src="https://cdn.jsdelivr.net/npm/d3@7"></script>
    <html lang="en">
        <h1 id="main"></h1>
    </html>
    <script>
        const div = document.getElementById('main');
        div.textContent = ``;
    </script>
    ```
##  Fetching the observations 
To retrieve the patient data we use the [Data Module](/sdk/data/). Specifically, the [`Observation`](/sdk/data-observation/) model.
Here, we can use `self.target`, which is the patient's `id`, to retrieve the patient and their observations by filtering for the values we need — such as weight, height, etc.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.v1.data.observation import Observation
    from canvas_sdk.v1.data.patient import Patient
    def handle(self) -> list[Effect]:
        patient = Patient.objects.get(id=self.target)
        sex_at_birth = patient.sex_at_birth
        birth_date = patient.birth_date
        observation_weight = Observation.objects.for_patient(self.target).filter(name="weight")
        observation_length = Observation.objects.for_patient(self.target).filter(name="length")
        observation_bmi = Observation.objects.for_patient(self.target).filter(name="bmi")
        observation_head_circumference = Observation.objects.for_patient(self.target).filter(name="head_circumference")
    ```
##  Tying it all together 
We now know:
  1. How to put a button in the chart
  2. How to launch a modal when that button is clicked
  3. How to create an HTML template to render within that modal
  4. How to retrieve data to use within that HTML template
All that's left is combining these actions into a useful data visualization for our clinical users.
You can see our HTML template [here](https://github.com/Medical-Software-Foundation/canvas/blob/main/extensions/growth_charts/templates/chart.html), which draws many charts based on the observations provided and the percentile curve data provided by the CDC. To make that percentile data usable in our template, we transformed the Excel files from the CDC website into structured data we could use programatically. You can find those python representations of the percentile data [here](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/growth_charts/graphs).
Here's an excerpt:
    ```python
    who_boys_length_age = [
        { "x": 0, "y": 46.77032, "z": "5th" },
        { "x": 1, "y": 51.52262, "z": "5th" },
        { "x": 2, "y": 55.13442, "z": "5th" },
        ...,
        { "x": 23, "y": 92.93123, "z": "98th" },
        { "x": 24, "y": 93.92634, "z": "98th" }
    ]
    ```
In addition to the percentile data series, we of course need to plot the patient observation data series. To do this, we create a lists of x and y values corresponding to the patient's age and measurements. You can see this in more detail in the [GitHub repo](https://github.com/Medical-Software-Foundation/canvas/blob/5e8a3dfdb18307e596d2da2d9fce33a3e379cd11/extensions/growth_charts/protocols/growth_charts.py#L80), but here's an excerpt:
    ```python
    import arrow
    import datetime
    from canvas_sdk.effects import Effect
    from canvas_sdk.v1.data.note import Note
    from canvas_sdk.v1.data.observation import Observation
    from canvas_sdk.v1.data.patient import Patient
    def convert_oz_to_kg(oz: str) -> float:
        return float(oz) * 0.0283495
    def get_age_in_months(birth_date: datetime.date, date: datetime.date = datetime.datetime.now()) -> int:
        now = arrow.get(date)
        date = arrow.get(birth_date)
        year_difference = now.year - date.year
        month_difference = now.month - date.month
        return year_difference * 12 + month_difference
    def handle(self) -> list[Effect]:
        graphs = []
        patient = Patient.objects.get(id=self.target)
        sex_at_birth = patient.sex_at_birth
        birth_date = patient.birth_date
        age_in_months = get_age_in_months(birth_date)
        is_less_than_24_months_old = age_in_months < 24
        is_less_than_36_months_old = age_in_months < 36
        observation_weight = Observation.objects.for_patient(self.target).filter(name="weight")
        observation_height = Observation.objects.for_patient(self.target).filter(name="height")
        observation_length = Observation.objects.for_patient(self.target).filter(name="length")
        observation_bmi = Observation.objects.for_patient(self.target).filter(name="bmi")
        observation_head_circumference = Observation.objects.for_patient(self.target).filter(name="head_circumference")
        weight_for_age = {}
        length_for_age = {}
        weight_for_length = {}
        head_for_age = {}
        bmi_for_age = {}
        for obs in observation_weight:
            if obs.value:
                note = Note.objects.get(dbid=obs.note_id)
                age_in_months = get_age_in_months(birth_date, note.datetime_of_service)
                weight_in_kg = convert_oz_to_kg(obs.value)
                weight_for_age[age_in_months] = weight_in_kg
        # ... repeat for other data series
    ```
Finally, we create a list of graphs with the necessary variables and data, which are passed to the template to generate and render the graph.
    ```python
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.templates import render_to_string
    who_boys_length_age = ... # from growth_charts.graphs.who_boys_length_age
    class Handler(BaseHandler):
        def compute(self):
            # list of graphs
            length_for_age = {} # filled in the actual implementation, see linked GitHub repository
            graphs = [
                {
                    "data": who_boys_length_age, # the data from the graph file
                    "title": 'Length for age (Boys 0 - 2 years)', # graph title
                    "xType": 'Generic', # the type of x axis (Generic, Length, Weight) - We need this info to convert the values
                    "yType": 'Length', # the type of y axis (Generic, Length, Weight)
                    "xLabel": 'Age', # label for the x axis
                    "yLabel": 'Length', # label for the y axis
                    "zLabel": 'Percentile', # label for the z axis
                    "layerData": length_for_age, # the patient's data that will be plotted on the graph
                    "tab": "WHO" # the section where the graph should be rendered (WHO or CDC)
                },
                # ...repeat for other data series
            ]
            launch_modal = LaunchModalEffect(
                content=render_to_string("templates/chart.html", {"graphs": graphs}),
            )
            return [launch_modal.apply()]
    ```

By combining action buttons, the data module, and the `LaunchModalEffect`, you can create unique visualizations to help contextualize patient data for your clinical users.

# Improve HCC Coding Accuracy

Source: https://docs.canvasmedical.com/guides/improve-hcc-coding-accuracy/

Different patients present unique challenges, and your tools should adapt to meet their specific needs.
Hierarchical condition category (HCC) coding is a critical component of value-based care, especially for organizations serving Medicare Advantage patients. Accurate risk adjustment ensures patients receive appropriate coverage while aligning reimbursement with the complexity of their care needs. However, navigating HCC coding can feel overwhelming with so many diagnoses to consider, guidelines to follow, and tools to use.
This guide will walk you through practical steps to use HCC codings in Canvas for more efficient and effective care delivery. You'll learn how to leverage our [HCC capture plugin](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/hcc_capture) to do the following:
  - Create coding gaps from external data using the FHIR DetectedIssue endpoint
  - Surface coding gaps as actionable protocol cards
  - Address and resolve codings gaps seamlessly within the clinical workflow through streamlined commands.
  - Annotate ICD-10 codes that are mapped to HCC categories
By surfacing relevant data when and where it's needed, you can eliminate unnecessary steps, reduce cognitive load, and keep workflows aligned with patient needs.
##  Create Coding Gaps via FHIR Detected Issue 
The [DetectedIssue FHIR resource](/api/detectedissue)) can be used to surface an actual or potential clinical issue with or between one or more active or proposed clinical actions for a patient; e.g. Drug-drug interaction, ineffective treatment frequency, procedure-condition conflict, gaps in care, etc.
A key use case is surfacing potential codings gaps that come from external sources.
The workflow within Canvas is centered around issues created with the `DetectedIssue.code` set to `CODINGGAP`. Although we are leveraging it in our R4 endpoint, `CODINGGAP` was introduced to the value set in R5, and can be used for surfacing conditions that may be present on historical claims but not yet diagnosed within the current year, suspect conditions, or condition data from external sources. The code should be structured as follows:
    ```json
        "code": {
            "coding": [
                {
                    "system": "https://terminology.hl7.org/CodeSystem/v3-ActCode",
                    "code": "CODINGGAP"
                }
            ]
        },
    ```
The ICD-10 code can be added to `DetectedIssue.evidence` attribute.
Validated coding gaps (where `DetectedIssue.status` = `preliminary`) will appear in the patient summary if the coding gap commands are enabled in your environment (see more below).
##  Surface New Coding Gaps as Protocol Cards 
Clinical Documentation Improvement (CDI) staff often play a crucial role in reviewing potential coding gaps, especially those added via the API using external data.
There is no built in UI feature in Canvas that surfaces coding gaps that have yet to be reviewed for accuracy by staff members. Instead, We haven chosen to leverage plugins to allow for customization within your workflow for surfacing gaps in care. The example protocol below creates a [protocol card](/sdk/effect-protocol-cards/) when a new DetectedIssue is created for a coding gap with a `registered` status. It then recommends that a staff member validates the information before presenting it to a clinician in the summary.
The protocol will surface in each patient's chart and staff can also leverage the population page as a work list.

            else:
                return self.resolve_coding_gaps_protocol_card(patient)
    ```
##  Use Coding Gap Commands to Update the Patient's Record 
The API can be leveraged to create coding gaps in various states. There are also 4 commands for clinicians and staff to manage coding gaps.
  - **Create Coding Gap** serves as a manual way to add coding gaps to the chart. Staff have the ability to create and validate in the same step.
  - **Validate Coding Gap** allows the care team (often CDI Reviewers) to review the external date and confirm that the gap should be surfaced to a clinician.
  - **Assess Coding Gap** allows clinicians to accept or refute the diagnose and choose the appropriate diagnosis to add to the visit.
  - **Defer Coding Gap** allows clinicians to acknowledge the gap and snooze it for a period of time so that they can return to it at a later date. This may be necessary if the patient is unable to provide enough detail or they run out of time during a visit. When recapture rate is an important metric, this allow reporting to reflect an action was taken.
##  Annotate ICD-10 Codes 
Adding an HCC tag as an annotation to ICD-10 is an easy way to increase awareness for clinicians. The example handlers below leverage a static list of ICD-codes. You could also reference a file contained within the plugin pacakge. Depending on which [HCC model](https://www.cms.gov/medicare/payment/medicare-advantage-rates-statistics/risk-adjustment) you follow, you can swap out the codes accordingly.
###  Adding "HCC" to Command Search Results 
The following handler leverages [command `POST_SEARCH` lifecycle events](/sdk/events/#command-lifecycle-events) and adds an `HCC` annotation to the associated ICD-10 codes within the results for the diagnose, past medical history, create coding gap, and assess coding gap commands.
    ```python
    import json
    from canvas_sdk.effects import Effect, EffectType
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    ICD_CODES = {
        "HCC": {"A0103", "A0104", "A0105", "A021", "A0222", "A0223", "A0224", "A065", "A072", "A202", "ADD_MORE_CODES..."}
    }
    class AnnotateSearchResults(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.DIAGNOSE__DIAGNOSE__POST_SEARCH),
            EventType.Name(EventType.MEDICAL_HISTORY__PAST_MEDICAL_HISTORY__POST_SEARCH),
            EventType.Name(EventType.CREATE_CODING_GAP__DIAGNOSE__POST_SEARCH),
            EventType.Name(EventType.ASSESS_CODING_GAP__DIAGNOSE__POST_SEARCH),
        ]
        def compute(self):
            """
            Add HCC code annotation if the HCC code is found in the search results.
            """
            results = self.context.get("results")
            if results is None:
                return [Effect(type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS, payload=json.dumps(None))]
            post_processed_results = []
            for result in self.context["results"]:
                for coding in result.get("extra", {}).get("coding", []):
                    if not coding.get("system") in ("http://hl7.org/fhir/sid/icd-10", "ICD-10"):
                        continue
                    if coding.get("code") in ICD_CODES["HCC"]:
                        if result.get("annotations") is None:
                            result["annotations"] = []
                        result["annotations"].append("HCC")
                        break
                post_processed_results.append(result)
            return [
                Effect(
                    type=EffectType.AUTOCOMPLETE_SEARCH_RESULTS,
                    payload=json.dumps(post_processed_results),
                )
            ]
    ```
###  Adding Annotations to Conditions and Detected Issues 
The following event/effect pairings can be leveraged to add annotations (such as the `HCC` tag) to conditions and detected issues in the patient summary as well as on claims using the handler code below.
  - `CLAIM__CONDITIONS` and `ANNOTATE_CLAIM_CONDITION_RESULTS`
  - `PATIENT_CHART__CONDITIONS` and `ANNOTATE_PATIENT_CHART_CONDITION_RESULTS`
  - `PATIENT_CHART__DETECTED_ISSUES` and `ANNOTATE_PATIENT_CHART_DETECTED_ISSUE_RESULTS`

# Note Management External Application Integration Guide

Source: https://docs.canvasmedical.com/guides/note-management-oauth/

This guide demonstrates how to build an external application that integrates with Canvas Medical using OAuth 2.0 authentication to manage notes (lock, sign, unlock, check-in, no-show).

##  Overview 
[Note Management Plugin](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins/note_management_app/note_management_app) demonstrates a complete integration pattern for external applications that need to:
  1. Authorize users via OAuth 2.0 Authorization Code Flow with PKCE
  2. Automatically refresh access tokens
  3. Call Canvas Simple API endpoints to perform note operations
###  Key Components 
  - **Application Handler** : Launches the web application in a new tab
  - **HTML Application** : Single-page application with OAuth flow and note management UI
  - **API Endpoints** : RESTful API for note operations (lock, sign, unlock, check-in, no-show)
* * *
##  OAuth 2.0 Setup 
###  Step 1: Create an OAuth Application in Canvas 
  1. Log in to your Canvas instance as an administrator
  2. Navigate to **Settings > Integrations > OAuth Applications**
  3. Click **Create Application**
  4. Configure the application:
     - **Name** : `Note Management App` (or your preferred name)
     - **Client Type** : `Public` (for browser-based apps that cannot securely store client secrets)
     - **Authorization Grant Type** : `Authorization Code`
     - **Redirect URIs** : Add your application's redirect URI
       - For production: `https://your-instance.canvasmedical.com/plugin-io/api/note_sign_api/app`
     - **Scopes** : Add `offline_access` (this allows the app to receive refresh tokens)
  5. **Save** the application
  6. Copy the **Client ID** \- you'll need this in the next step
###  Step 2. Install the Plugin 
    ```bash
    canvas install note_management_app/note_management_app --secret client_id=<YOUR_CLIENT_ID>
    ```
###  OAuth Flow Details 
####  Authorization Code Flow with PKCE 
This application implements the OAuth 2.0 Authorization Code Flow with Proof Key for Code Exchange (PKCE), which is the recommended flow for public clients (browser-based applications).
**Why PKCE?**
  - Protects against authorization code interception attacks
  - No client secret needed (suitable for public clients)
  - More secure for browser-based applications
**Flow Steps:**
  1. **Generate Code Verifier and Challenge**
         ```javascript
         // Generate a random string (43-128 characters)
         const codeVerifier = generateRandomString(128);
         // Create SHA-256 hash and base64url encode
         const codeChallenge = await generateCodeChallenge(codeVerifier);
         ```
  2. **Authorization Request**
         ```shell
         GET /auth/authorize/?
           response_type=code&
           client_id={CLIENT_ID}&
           redirect_uri={REDIRECT_URI}&
           scope=offline_access&
           code_challenge={CODE_CHALLENGE}&
           code_challenge_method=S256&
           launch=e30K
         ```
**Parameters:**
     - `response_type=code`: Request an authorization code
     - `client_id`: Your application's client ID
     - `redirect_uri`: Where Canvas will redirect after authorization
     - `scope=offline_access`: Request a refresh token for long-lived access
     - `code_challenge`: Base64url-encoded SHA-256 hash of the code verifier
     - `code_challenge_method=S256`: Indicates SHA-256 hashing
     - `launch=e30K`: Launch context (base64-encoded empty JSON object `{}`)
  3. **User Authorization**
     - User is redirected to Canvas login/authorization page
     - User authenticates and authorizes the application
     - Canvas redirects back to `redirect_uri` with an authorization code
  4. **Token Exchange**
         ```javascript
         POST /auth/token/
         Content-Type: application/x-www-form-urlencoded
         grant_type=authorization_code&
         code={AUTHORIZATION_CODE}&
         redirect_uri={REDIRECT_URI}&
         client_id={CLIENT_ID}&
         code_verifier={CODE_VERIFIER}
         ```
**Response:**
         ```json
         {
           "access_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
           "refresh_token": "6KHq3fjkSWQ1vaBbF6WHG9...",
           "token_type": "Bearer",
           "expires_in": 36000,
           "scope": "offline_access"
         }
         ```
**Token Lifetimes:**
     - **Access Token** : Valid for 10 hours (36,000 seconds)
     - **Refresh Token** : Non-expiring, single-use token
  5. **Token Refresh**
         ```javascript
         POST /auth/token/
         Content-Type: application/x-www-form-urlencoded
         grant_type=refresh_token&
         refresh_token={REFRESH_TOKEN}&
         client_id={CLIENT_ID}&
         scope=offline_access
         ```
**Response:** Returns new access token and new refresh token

    ```
###  Component Overview 
####  1\. Application Handler (`handlers/application.py`) 
The Application handler launches the web application when triggered:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class NoteManagementApplication(Application):
        """External note management application with OAuth integration."""
        def on_open(self) -> Effect:
            """Handle the application open event.
            Launches the note management application in a new window.
            """
            # Build the URL to the API endpoint that serves the HTML
            # Using relative path - Canvas will resolve to the correct instance
            app_url = "/plugin-io/api/note_sign_api/app"
            return LaunchModalEffect(
                url=app_url,
                target=LaunchModalEffect.TargetType.NEW_WINDOW,
            ).apply()
    ```
####  2\. App API Handler (`handlers/api.py` \- AppApi class) 
Serves the HTML application:
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note import Note
    from canvas_sdk.effects.simple_api import HTMLResponse, JSONResponse, Response
    from canvas_sdk.handlers.simple_api import Credentials, SimpleAPI, api
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Note as NoteModel
    class AppApi(SimpleAPI):
        """API handler for serving the note management application."""
        PREFIX = ""
        def authenticate(self, credentials: Credentials) -> bool:
            """Allow access without authentication.
            The OAuth flow will handle authentication within the app.
            """
            return True
        @api.get("/app")
        def note_management_app(self) -> list[Response | Effect]:
            """Serve the note management application HTML."""
            # Get the Canvas instance URL from the request Host header
            host = self.request.headers.get("Host", "localhost:8000")
            # Determine protocol based on host
            if "localhost" in host or "127.0.0.1" in host:
                canvas_instance = f"http://{host}"
            else:
                canvas_instance = f"https://{host}"
            # Render the HTML template with context
            context = {"canvas_instance": canvas_instance}
            return [
                HTMLResponse(
                    render_to_string("templates/note_management_app.html", context),
                    status_code=HTTPStatus.OK,
                )
            ]
    ```
####  3\. Note API Handler (`handlers/api.py` \- NoteApi class) 
Provides RESTful API endpoints for note operations:
    ```python
    from http import HTTPStatus
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.note import Note
    from canvas_sdk.effects.simple_api import HTMLResponse, JSONResponse, Response
    from canvas_sdk.handlers.simple_api import Credentials, SimpleAPI, api
    from canvas_sdk.templates import render_to_string
    from canvas_sdk.v1.data import Note as NoteModel
    class NoteApi(SimpleAPI):
        """API handler for note-related operations."""
        PREFIX = "/notes"
        def authenticate(self, credentials: Credentials) -> bool:
            """Authenticate requests."""
            return self.event.actor.instance is not None
        @api.post("/<id>/lock")
        def lock_note(self) -> list[Response | Effect]:
            """Lock a note."""
            note_id = self.request.path_params["id"]
            try:
                note_instance = NoteModel.objects.get(id=note_id)
            except NoteModel.DoesNotExist:
                return [
                    JSONResponse(
                        {"error": "Note not found."},
                        status_code=404,
                    )
                ]
            note = Note(instance_id=note_instance.id)
            return [note.lock()]
    ```
* * *
##  Implementation Details 
####  Key JavaScript Functions 
#####  PKCE Implementation 
    ```javascript
    // Generate random string for code verifier
    function generateRandomString(length) {
        const charset = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~';
        let result = '';
        const randomValues = new Uint8Array(length);
        crypto.getRandomValues(randomValues);
        for (let i = 0; i < length; i++) {
            result += charset[randomValues[i] % charset.length];
        }
        return result;
    }
    // Generate code challenge from verifier
    async function generateCodeChallenge(codeVerifier) {
        const encoder = new TextEncoder();
        const data = encoder.encode(codeVerifier);
        const hash = await crypto.subtle.digest('SHA-256', data);
        const base64 = btoa(String.fromCharCode(...new Uint8Array(hash)));
        return base64.replace(//g, '-').replace(/\//g, '_').replace(/=/g, '');
    }
    ```
#####  OAuth Initiation 
    ```javascript
    async function initiateOAuth() {
        // Generate PKCE values
        const codeVerifier = generateRandomString(128);
        const codeChallenge = await generateCodeChallenge(codeVerifier);
        // Store verifier for token exchange
        sessionStorage.setItem('code_verifier', codeVerifier);
        // Build authorization URL
        const authUrl = `${CANVAS_INSTANCE}/auth/authorize/?` +
            `response_type=code` +
            `&client_id=${encodeURIComponent(CLIENT_ID)}` +
            `&redirect_uri=${encodeURIComponent(REDIRECT_URI)}` +
            `&scope=${encodeURIComponent(SCOPES)}` +
            `&code_challenge=${codeChallenge}` +
            `&code_challenge_method=S256` +
            `&launch=${LAUNCH_CONTEXT}`;
        // Redirect to Canvas authorization
        window.location.href = authUrl;
    }
    ```
#####  Token Exchange 
    ```javascript
    async function handleAuthCallback() {
        const urlParams = new URLSearchParams(window.location.search);
        const code = urlParams.get('code');
        if (code) {
            const codeVerifier = sessionStorage.getItem('code_verifier');
            const response = await fetch(`${CANVAS_INSTANCE}/auth/token/`, {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded',
                },
                body: new URLSearchParams({
                    grant_type: 'authorization_code',
                    code: code,
                    redirect_uri: REDIRECT_URI,
                    client_id: CLIENT_ID,
                    code_verifier: codeVerifier
                })
            });
            const data = await response.json();
            saveTokens(data);
            // Clean up
            window.history.replaceState({}, document.title, window.location.pathname);
            sessionStorage.removeItem('code_verifier');
            updateUI();
        }
    }
    ```
#####  Token Storage and Refresh 
    ```javascript
    function saveTokens(tokenData) {
        localStorage.setItem(ACCESS_TOKEN_KEY, tokenData.access_token);
        localStorage.setItem(REFRESH_TOKEN_KEY, tokenData.refresh_token);
        // Calculate expiry time
        const expiryTime = Date.now() + (tokenData.expires_in * 1000);
        localStorage.setItem(TOKEN_EXPIRY_KEY, expiryTime.toString());
        // Schedule refresh 5 minutes before expiry
        scheduleTokenRefresh(tokenData.expires_in - 300);
    }
    async function refreshAccessToken() {
        const refreshToken = localStorage.getItem(REFRESH_TOKEN_KEY);
        const response = await fetch(`${CANVAS_INSTANCE}/auth/token/`, {
            method: 'POST',
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded',
            },
            body: new URLSearchParams({
                grant_type: 'refresh_token',
                refresh_token: refreshToken,
                client_id: CLIENT_ID
            })
        });
        const data = await response.json();
        saveTokens(data);
        showSuccess('Access token refreshed automatically');
    }
    ```
#####  API Calls 
    ```javascript
    async function performAction(action) {
        const noteId = document.getElementById('noteId').value.trim();
        const accessToken = localStorage.getItem(ACCESS_TOKEN_KEY);
        const actionMap = {
            'lock': '/lock',
            'sign': '/sign',
            'unlock': '/unlock',
            'lock_sign': '/lock_sign',
            'checkin': '/checkin',
            'noshow': '/noshow'
        };
        const endpoint = actionMap[action];
        const response = await fetch(
            `${CANVAS_INSTANCE}/plugins/note_sign_api/notes/${noteId}${endpoint}`,
            {
                method: 'POST',
                headers: {
                    'Authorization': `Bearer ${accessToken}`,
                    'Content-Type': 'application/json'
                }
            }
        );
        if (!response.ok) {
            // Handle errors, possibly refresh token if 401
            if (response.status === 401) {
                await refreshAccessToken();
            }
        }
    }
    ```
* * *
##  API Endpoints 
###  Base URL 
All plugin API endpoints are prefixed with:
    ```shell
    https://your-instance.canvasmedical.com/plugin-io/api/note_sign_api/
    ```
###  Available Endpoints 
####  1\. Serve Application 
    ```shell
    GET /app
    ```
**Description** : Serves the HTML application
* * *
####  2\. Lock Note 
    ```shell
    POST /notes/<note_id>/lock
    ```
**Description** : Locks a note to prevent further editing
* * *
####  3\. Sign Note 
    ```shell

    POST /notes/<note_id>/noshow
    ```
**Description** : Marks an appointment as no-show
* * *
##  Security Considerations 
###  1\. Token Storage 
**Current Implementation** : Tokens are stored in `localStorage`
**Considerations** :
  - `localStorage` is vulnerable to XSS attacks
  - For production, consider using:
    - HTTP-only cookies (requires backend support)
    - Session storage (cleared when tab closes)
    - Encrypted storage solutions
###  2\. PKCE Protection 
  - PKCE prevents authorization code interception attacks
  - Code verifier is stored in `sessionStorage` (temporary)
  - Code challenge is sent to authorization server
  - Server verifies verifier matches challenge during token exchange
###  3\. Token Refresh 
  - Refresh tokens are single-use (Canvas rotates them)
  - Access tokens are short-lived (10 hours)
  - Automatic refresh happens before expiry
  - Failed refresh triggers re-authentication
###  4\. API Authentication 
> **⚠️ Important** : The current implementation relies on the OAuth-authenticated user from Canvas. This is a simplified example for demonstration purposes.
**Current Implementation** :
    ```python
    from canvas_sdk.handlers.simple_api import Credentials
    def authenticate(self, credentials: Credentials) -> bool:
        return self.event.actor.instance is not None
    ```
This basic authentication check verifies that there is an authenticated Canvas user making the request.
**Production Recommendations** :
See the official documentation for supported authentication mechanisms: [Canvas SDK Authentication Guide](https://docs.canvasmedical.com/sdk/handlers-simple-api-http/#authentication)

# How to group items on a patient chart section

Source: https://docs.canvasmedical.com/guides/patient-chart-group-items/

This guide explains how to group items on a patient chart section. With this, you can define custom groups to organize medications, conditions, or detected issues.
Currently, this is supported for the Conditions, Medications, and Detected Issues sections.
##  What you'll learn: 
  - Use the [`PatientChartGroup`](/sdk/patient-chart-group-effect) effect to group items in a section by priority.
  - Group conditions based on ICD-10 code ranges
  - Group detected issues (such as coding gaps) by custom criteria
##  Patient Chart Group 
The `PatientChartGroup` effect allows you to group items in a patient chart section. You can define multiple groups with a name, priority, and the items that belong to each group.
####  3\. The plugin 
Here's an example of a plugin that groups conditions based on their codes - here we are creating a "Psychiatry" group for ICD-10 codes F01-F99 and R45.x and placing all matching conditions in that group.
    ```python
    from canvas_sdk.effects.patient_chart_group import PatientChartGroup
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.group import Group
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.commands.constants import CodeSystems
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART__CONDITIONS)
        def compute(self) -> list[Effect]:
            groups: dict[str, Group] = {}
            groups.setdefault("Psychiatry", Group(priority=100, items=[], name="Psychiatry"))
            for condition in self.event.context:
               for coding in condition["codings"]:
                   if coding["system"] == CodeSystems.ICD10 and ("F01" <= coding["code"] <= "F99" or coding["code"].startswith("R45.")):
                       groups["Psychiatry"].items.append(condition)
                       break
            return [PatientChartGroup(items=groups).apply()]
    ```
####  4\. The Output 
Below, you can see how it will appear in the app.
![patient chart group](/assets/images/patient-chart-group.png)
##  Grouping Detected Issues 
You can also group detected issues, such as coding gaps, using the same approach. Here's an example that groups detected issues by their status or other criteria:
    ```python
    from canvas_sdk.effects.patient_chart_group import PatientChartGroup
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.group import Group
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class GroupDetectedIssues(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART__DETECTED_ISSUES)
        def compute(self) -> list[Effect]:
            groups: dict[str, Group] = {}
            groups.setdefault("High Priority", Group(priority=200, items=[], name="High Priority"))
            groups.setdefault("Standard", Group(priority=100, items=[], name="Standard"))
            for detected_issue in self.event.context:
                # Group by custom logic - for example, based on evidence or other attributes
                # Note: The context for detected issues contains only the "id" field
                # You may need to query additional data using the SDK if needed
                # Example: place first 5 in high priority, rest in standard
                if len(groups["High Priority"].items) < 5:
                    groups["High Priority"].items.append(detected_issue)
                else:
                    groups["Standard"].items.append(detected_issue)
            return [PatientChartGroup(items=groups).apply()]
    ```
**Note:** The context structure for detected issues differs from conditions and medications. The `PATIENT_CHART__DETECTED_ISSUES` event context includes only the `id` field for each detected issue. If you need additional information (such as evidence, status, or code) to determine grouping logic, you'll need to query the detected issue data using the Canvas SDK's data models.

# Platform Security Overview

Source: https://docs.canvasmedical.com/guides/platform-security-overview/

This page describes how Canvas is deployed, where its trust boundaries sit, and which security controls are in force before any plugin, integration, or custom code is introduced. It is intended for security and compliance teams evaluating Canvas, and for implementers who need to know which controls they inherit and which they own.
Canvas holds HITRUST CSF r2 certification. The certification report, SOC-equivalent artifacts, and the most recent independent penetration test are available under NDA through your Canvas contact.
##  Deployment and tenancy model 
Every Canvas customer runs on a **dedicated instance** : its own set of immutable application containers and its own database. Customer data is separated at the database level rather than by a row- or column-scoped partition inside a shared store, so there is no query path from one customer's application to another customer's data.
Instances are hosted on Aptible, which runs on AWS in `us-east-1`, inside a segregated virtual private cloud. Application containers are rebuilt from a pinned image on each deploy rather than mutated in place.
##  Trust boundaries 
Requests cross five boundaries, each of which enforces its own controls:
Boundary| Responsibility  
---|---  
Edge| TLS termination, IP allow-listing, rate limiting, WAF and DDoS protection  
Core application| Authentication, session handling, role- and object-level authorization  
Plugin runner| Isolated execution of customer plugin code — see [Plugin Security Model](/guides/plugin-security-model/)  
FHIR API| Scoped, token-based access with patient-context enforcement  
Per-customer database| Tenant-isolated persistence, encrypted at rest  
##  Platform controls 
These apply to every instance and are not customer-configurable.
###  Encryption 
Traffic to and between Canvas services is encrypted with TLS. Databases and disk volumes are encrypted at rest with AES-256. Patient documents stored in object storage are encrypted at rest with AES-256 server-side encryption.
###  Identity and authentication 
Canvas supports SSO via SAML. Where an instance uses SSO — the recommended configuration — password policy, multi-factor authentication, session lifetime, and account lifecycle are governed by your identity provider, and Canvas neither stores nor validates those credentials. Deprovisioning a user at your identity provider removes their access to Canvas.
Where an instance uses Canvas-managed credentials instead, passwords are validated against minimum length, similarity to the user's own name and username, entirely-numeric values, and a list of commonly-used passwords.
Failed-login lockout applies to interactive sessions on either path, independent of the identity provider.
###  Authorization 
Access is governed by role-based access control. Permissions are evaluated at two levels:
  - **Model permissions** determine which record types a user may read or modify.
  - **Object permissions** narrow that further to specific records, scoped by patient group.
Both are administered through roles and groups rather than granted to individuals directly.
###  Network 
Each instance's externally reachable endpoints carry IP allow-lists backed by cloud security groups. Internal services are not exposed to the public internet. Administrative access to Canvas infrastructure requires authentication through the corporate identity provider and traverses a VPN.
###  Privileged access 
Access to production containers is restricted by role. Sessions are recorded end to end, and the resulting logs are retained and reviewable.
##  Shared responsibility 
Canvas operates the platform and its controls. The following remain with the customer:
Area| Customer responsibility  
---|---  
Identity| Enforcing MFA, provisioning and deprovisioning users, periodic access review  
Authorization| Assigning roles and groups according to least privilege  
Plugins and extensions| Reviewing and approving code deployed to your instance — see [Plugin Security Model](/guides/plugin-security-model/)  
Credentials| Custody of API keys, OAuth client secrets, and plugin secrets  
Exported data| Protecting data once it leaves Canvas through an API, export, or replica  
> **Info:** Installing a plugin requires a credential your organization controls, so your own review process can gate what reaches production. See Deployment governance in the Plugin Security Model guide.

# Plugin Security Model

Source: https://docs.canvasmedical.com/guides/plugin-security-model/

Plugins let you extend Canvas with your own logic. Because that logic runs inside a system holding patient data, the plugin runtime is deliberately constrained. This page describes those constraints and the deployment controls available to you, so your security team can evaluate what plugin code can and cannot do.
##  Execution model 
Plugins do not manipulate Canvas data directly. They **subscribe to events** and **return declarative effects** that the platform interprets and applies.
That indirection is the core of the model. A plugin describes an intended outcome — add a banner, create a command, send a notification — and the platform decides whether and how to carry it out, applying the same validation and permission rules it applies to any other write. A plugin cannot reach past the effect layer to mutate records itself.
##  Runtime isolation 
The plugin runner executes customer code under several layers of containment:
  - **Process and user isolation.** Plugin code runs in a separate operating-system user and process from the core application.
  - **Restricted interpreter.** Code executes in a RestrictedPython sandbox with an explicit allowlist of importable modules. Modules outside that list are rejected at load time, not at run time.
  - **No direct system access.** Plugins have no direct database connection, no filesystem access, and no operating-system access.
  - **Constrained network surface.** Outbound communication is limited to HTTP and HTTPS through the SDK's supported clients. Raw sockets and non-HTTP protocol libraries are not available in the sandbox.
  - **Package integrity.** Plugin packages are checksummed, and the manifest is validated before a plugin is installed.
Because the module allowlist is enforced when the plugin is loaded, a plugin that attempts a disallowed import fails to install rather than failing partway through a patient-facing workflow.
##  Secrets 
Plugins declare the secrets they need in their manifest, and values are supplied per instance. Secret values are **write-only** from the plugin author's perspective: they can be set and used at runtime, but not read back out through the interface used to configure them.
Treat plugin secrets like any other production credential — scope them narrowly, and rotate them on the same cadence as the rest of your estate.
##  API access 
Where a plugin or external application reaches Canvas through the FHIR API, access is scoped by OAuth token, and patient-context enforcement applies to patient-scoped launches. See [Customer Authentication](/api/customer-authentication/) and [Authentication Best Practices](/api/authentication-best-practices/).
##  Deployment governance 
###  Who can install 
Installing or updating a plugin is an authenticated operation: it requires an OAuth token carrying the plugin scope for your instance. Controlling who holds that credential is the primary control over what reaches your production environment, and it is a control your organization owns.
###  Installing from your own pipeline 
Most organizations keep plugin source in their own repository and install from their own continuous-integration pipeline rather than from individual workstations. Under that arrangement the installing credential lives in CI, and your existing review process — pull-request approval, required checks, protected branches — is what gates production.
Canvas recommends this pattern where your change-management policy requires documented human review before code runs in production.
> **Info:** Plugins built through Canvas Studio follow their own staged workflow, with explicit approval steps before a project is published.
###  Environment separation 
Instances are provisioned per environment, and release channels let you promote a plugin through a lower environment before it reaches production. Deploys are pinned to a specific commit, so what you reviewed is what runs.
###  Change tracking 
Plugin deployment activity is tracked, and plugin runtime activity is instrumented per plugin. Combined with the audit trail described in [Audit Logging and Telemetry](/guides/audit-logging-and-telemetry/), this gives you a record of both what changed and what the plugin did.
##  Recommended practices 
  - Hold the installing credential in CI rather than on workstations, so your pull-request review is what gates production.
  - Scope plugin secrets to the minimum required, and rotate them on your normal cadence.
  - Exercise plugins in a lower environment before promoting to production.

# Populating Command Fields

Source: https://docs.canvasmedical.com/guides/populating-command-fields/

When a provider works with a command in the Canvas UI — Diagnose, Prescribe, Allergy, Refer, and the rest — most fields are backed by an interactive control. You start typing "type 2 diabetes" and the chart autocompletes to an ICD-10 code, you pick a pharmacy from a searchable list, and you choose a severity from a dropdown. The UI does the lookup for you and stores the underlying code, id, or enum value on the command.
When you build those same commands with the [commands module](/sdk/commands/) in a plugin, there is no interactive control. A command field takes the **raw value** — an FDB code, a database id, an ICD-10 code, an enum member — and it is your plugin's job to supply the correct one. This guide shows you where those values come from so your automated charting behaves like a provider working in the UI.
> **Info:** Rule of thumb: if a field is an autocomplete, search box, or dropdown in the UI, it is not free text in the SDK — you must look up the value first.
##  The three sources of command values 
Every value that a UI control would supply comes from one of three places:
In the UI it looks like…| In the SDK you get the value from…| Example  
---|---|---  
A **dropdown** of fixed choices| An **enum** under [Command Constants](/sdk/commands/#command-constants) or the command class| `AllergyCommand.Severity`, `AssigneeType`, `PulseRhythm`  
An **autocomplete of things already on the chart** (or a reference table)| A **[data module](/sdk/data/)** query| An existing `Condition` to assess, a `Staff` key, a `TaskLabel`  
An **autocomplete that searches a terminology** (medications, codes, contacts)| A **[utils HTTP helper](/sdk/utils/)** (Ontologies / Pharmacy / Science)| Search FDB for a drug, ICD-10 for a diagnosis, a pharmacy by name  
The rest of this guide walks through each source.
##  1\. Enums and dropdowns → Command Constants 
Fixed-choice fields map to Python enums. Import the enum and pass a member — don't pass a bare string, and don't invent values. The shared enums are documented under [Command Constants](/sdk/commands/#command-constants); command-specific enums are listed in each command's section.
    ```python
    from canvas_sdk.commands import AllergyCommand
    allergy = AllergyCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        allergy_id="e5f6a7b8-9c0d-4e1f-8a2b-3c4d5e6f7a8b",
        severity=AllergyCommand.Severity.MODERATE,  # a dropdown in the UI
    )
    ```
Each enum's documentation lists both the member name and the stored value, so you can map an external system's value onto the correct member.
##  2\. Chart records and reference tables → data modules 
Many fields reference something that already exists in Canvas: a condition on the patient's problem list, a staff member, a questionnaire, a lab partner. In the UI these are autocompletes scoped to the chart or to a reference table. In the SDK you query the matching [data module](/sdk/data/) and pass the id it returns.
    ```python
    from canvas_sdk.commands import AssessCommand
    from canvas_sdk.v1.data import Condition
    patient_id = "e5f6a7b8-9c0d-4e1f-8a2b-3c4d5e6f7a8b"
    # The UI would let the provider pick from conditions already on the chart.
    # In a plugin, query for it and pass its id.
    condition = (
        Condition.objects.for_patient(patient_id).committed().active().first()
    )
    assess = AssessCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        condition_id=condition.id,
        status=AssessCommand.Status.STABLE,
    )
    ```
The description of each command field tells you which data module it points to and whether the record has to already be on **that patient's** chart. Common cases:
  - **Existing chart items** — the condition to assess or resolve, the medication to stop or change, the goal to close, the reports to review. Query the data module `for_patient(...)` and use the returned id.
  - **Reference tables** — a [Staff](/sdk/data-staff/#staff) key for an ordering provider, a [Questionnaire](/sdk/data-questionnaire/#questionnaire) to answer, a [LabPartner](/sdk/data-labs/) and its tests, a [TaskLabel](/sdk/data-task/#tasklabel) to apply, a [Vaccine](/sdk/data-vaccine/#vaccine) and its [lots](/sdk/data-vaccine/#vaccinelot) for an immunization. These aren't patient-scoped, but the value still has to match an existing record.
##  3\. Terminology search → utils HTTP helpers 
The richest autocompletes in the UI search a clinical terminology in real time: FDB for medications and allergens, ICD-10 for diagnoses, SNOMED for family/surgical history, a pharmacy directory, an imaging catalog. Those searches are exposed through the [utils](/sdk/utils/) HTTP clients so your plugin can run the same lookup and pass the resulting code.
Command field| Helper  
---|---  
Prescribe / MedicationStatement / Refill / AdjustPrescription medication (`fdb_code`, `new_fdb_code`)| [Searching for medications](/sdk/utils/#searching-for-medications) (Ontologies)  
Allergy allergen| [Searching for allergens](/sdk/utils/#searching-for-allergens) (Ontologies)  
Diagnose / Assess-adjacent ICD-10 codes| [Looking up clinical codes](/sdk/utils/#looking-up-clinical-codes) (Ontologies)  
Family History, Surgical History, Instruct concepts| [Searching clinical concepts](/sdk/utils/#searching-clinical-concepts) (Ontologies)  
Prescribe pharmacy (`pharmacy`)| [Searching for pharmacies](/sdk/utils/#searching-for-pharmacies) (Pharmacy)  
ImagingOrder image code| [Searching for imaging codes](/sdk/utils/#searching-for-imaging-codes) (Science)  
Refer / ImagingOrder / care-team service providers (including imaging centers)| [Searching for contacts and service providers](/sdk/utils/#searching-for-contacts-and-service-providers) (Science)  
For example, the UI autocompletes a diagnosis; a plugin searches ICD-10 and passes the code it finds:
    ```python
    import json
    from urllib.parse import urlencode
    from canvas_sdk.utils.http import ontologies_http
    from canvas_sdk.commands import DiagnoseCommand
    response = ontologies_http.get(
        f"/icd/condition/?{urlencode({'search': 'type 2 diabetes'})}"
    )
    first = json.loads(response.text)[0]
    diagnose = DiagnoseCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        icd10_code=first["icd10_code"],
    )
    ```
See the [utils](/sdk/utils/) reference for the parameters and response shape of each endpoint.
##  Putting it together 
A single command often draws on more than one source. A Prescribe command, for instance, combines a terminology search, a directory search, a reference-table id, and an enum:
    ```python
    from canvas_sdk.commands import PrescribeCommand
    from canvas_sdk.v1.data import Staff
    fdb_code = "..."               # from the medication search (utils)
    ncpdp_id = "..."               # from the pharmacy search (utils)
    staff = Staff.objects.first()  # the prescriber
    prescribe = PrescribeCommand(
        note_uuid="8f4b1e2c-9a3d-4c7e-b1f6-2d5a8c0e3b47",
        fdb_code=fdb_code,               # utils: medication search
        icd10_codes=["E119"],            # from the patient's active problem list
        pharmacy=ncpdp_id,               # utils: pharmacy search
        prescriber_id=staff.id,          # data module: Staff reference table
        substitutions=PrescribeCommand.Substitutions.ALLOWED,  # enum
        quantity_to_dispense=30,
    )
    ```
##  Interaction screening for medication commands 
In the Canvas UI, when a provider stages a medication command (such as Prescribe), Canvas automatically runs **drug–allergy** and **drug–drug** interaction screening and shows the results to the provider. When you originate or commit medication commands with the SDK — outside that interactive flow — this screening does **not** run automatically.
If you want the same safety net, you can opt in to running the checks yourself against the patient's allergy and medication lists using the ontologies screening endpoints, then act on the results before the command is committed:
Check| Helper  
---|---  
Drug–allergy| [Screening for drug–allergy interactions](/sdk/utils/#screening-for-drugallergy-interactions) (Ontologies)  
Drug–drug| [Screening for drug–drug interactions](/sdk/utils/#screening-for-drugdrug-interactions) (Ontologies)  
This is opt-in: only add it if your workflow charts medications programmatically and you want to reproduce the interaction warnings a provider would see in the UI.
##  Tips 
  - **Check the field description first.** Each command field in the [Commands reference](/sdk/commands/#commands) says whether it wants a code, an id, or an enum — and links to the data module or utils endpoint that supplies it.
  - **Match the UI's scoping.** If a field references something on the chart, query it `for_patient(...)` so you don't attach another patient's record.
  - **Handle "no match."** A search or query can come back empty. Decide what your plugin should do (skip the field, raise, or fall back) rather than passing a guess.
  - **Don't hard-code codes you can't verify.** Terminologies change; look values up so you stay in sync with what the chart would offer.

# How to add additional profile fields

Source: https://docs.canvasmedical.com/guides/profile-additional-fields/

This guide explains how to create additional fields that will appear on the patient profile demographics form. With this, you can define custom fields, and the information will be stored as patient metadata.
##  What you'll learn: 
  - Use the [`PatientMetadataCreateForm`](/sdk/patient-metadata-create-form-effect) effect to display additional fields on the patient profile.
  - Use the [`FormField`](/sdk/patient-metadata-create-form-effect/#formfield) class to create fields
##  Patient Metadata Create form plugin 
####  1\. FormField 
To create the form, we need to specify which items will be included. For this, we use the [`FormField`](/sdk/patient-metadata-create-form-effect/#formfield) class, where we can define our inputs and their attributes.
    ```python
    from canvas_sdk.effects.patient_metadata import InputType, FormField
    FormField(
        key='musicGenre',
        label='Preferred music genre',
        type=InputType.TEXT,
        required=False,
        editable=True,
    )
    ```
####  2\. PatientMetadataCreateFormEffect 
The next step is to add these fields to the effect so they can be used to build the form.
    ```python
    from canvas_sdk.effects.patient_metadata import PatientMetadataCreateFormEffect, InputType, FormField
    PatientMetadataCreateFormEffect(form_fields=[
        FormField(
            key='musicGenre',
            label='Preferred music genre',
            type=InputType.TEXT,
            required=False,
            editable=True,
        ),
        ...,
    ])
    ```
####  3\. The plugin 
Here's an example of a complete plugin showcasing the different input types.
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.patient_metadata import PatientMetadataCreateFormEffect, InputType, FormField
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    # Inherit from BaseHandler to properly get registered for events
    class Handler(BaseHandler):
        RESPONDS_TO = EventType.Name(EventType.PATIENT_METADATA__GET_ADDITIONAL_FIELDS)
        def compute(self) -> list[Effect]:
            form = PatientMetadataCreateFormEffect(form_fields=[
                FormField(
                    key='musicGenre',
                    label='Preferred music genre',
                    type=InputType.TEXT,
                    required=False,
                    editable=True,
                ),
                FormField(
                    key='occupation',
                    label='Occupation',
                    type=InputType.SELECT,
                    required=False,
                    editable=True,
                    options=["Engineer", "Teacher", "Other"]
                ),
                FormField(
                    key='date',
                    label='Date',
                    type=InputType.DATE,
                    required=False,
                    editable=True,
                ),
            ])
            return [form.apply()]
    ```
####  4\. The Output 
And that's it! Below, you can see how it will appear in the app — these fields will be stored as patient metadata.

# Roles and Permissions

Source: https://docs.canvasmedical.com/guides/roles-and-permissions/

Access in Canvas is governed by role-based access control. This page explains how authorization is evaluated, describes the roles every instance is provisioned with, and outlines how to extend them for your organization.
##  How authorization works 
Canvas evaluates two independent levels of permission on every request.
**Model permissions** determine which record types a user may act on, and which actions are allowed on each: view, add, change, or delete. A user who lacks the view permission on a record type cannot read it anywhere in the application, including through the API.
**Object permissions** narrow that further to specific records. Object scope is expressed through **patient groups** : a user may hold a permission on a record type in general but only exercise it for patients within the groups assigned to them. This is how an organization restricts a clinician to a panel, a site, or a program rather than the whole patient population.
Both levels are always evaluated together. A user must satisfy the model permission and the object permission — and be an active user — for access to be granted.
> **Info:** Permissions are granted to roles, never directly to individuals. Adding or removing a user's access means changing their role assignments, which makes access reviews a question of who holds which role rather than an audit of per-user exceptions.
Some capabilities are gated by **named feature permissions** rather than by a record type — printing, revenue, data integration, campaigns, the questionnaire builder, patient activation, and prescription cancellation among them. These behave identically in evaluation; they simply gate a feature rather than a model.
##  Default roles 
Every Canvas instance is provisioned with the roles below. They are grouped here by what they are for; in the admin console they appear as a flat list.
###  Broad functional roles 
Role| Grants  
---|---  
Administrative| Organization and practice-location configuration, staff records, note types, letter and questionnaire templates, and revenue configuration  
Clinical| Clinical configuration and care-team management, lab and imaging report templates, protocol versions, and reporting  
###  Record access, split by read and write 
These are deliberately separate so that read access can be granted without write access.
Role| Grants  
---|---  
Clinical read| View clinical records — notes, patients, lab and imaging reports, prescriptions, referrals, messages, and related clinical documents  
Clinical write| Create and modify clinical records, including notes, plans, prescriptions, referrals, and reasons for visit  
Profile read| View patient demographics, contacts, identification cards, and payment methods  
Profile write| Modify patient demographics, coverage, consents, contacts, authorizations, and payment details  
Document Read| View patient administrative documents  
Document Write| Modify patient administrative documents  
###  Feature and workflow access 
Role| Grants  
---|---  
Patient Create| Create new patient records  
Schedule write| Create and modify appointments  
Tasking Access| View and update tasks  
Printing Access| Print from the chart  
Revenue access| The revenue module and authorization management  
Data integration Access| The data integration module  
Patient Data Integration Access| Patient-level data integration tasks  
Questionnaire Builder Access| The questionnaire builder  
###  Security-sensitive roles 
Treat these as privileged. They should be assigned narrowly and reviewed on a defined cadence.
Role| Grants  
---|---  
Staff Permissions Access| Manage roles, groups, staff permissions, and patient-group membership — in effect, the ability to grant access to others  
Emergency Access| Break-glass access, recorded against a dedicated emergency-access record  
Admin Lockout| View and clear failed-login lockouts  
Lead| Manage multi-factor authentication devices for users, including TOTP, email, and SMS  
> **Warning:** Staff Permissions Access is the role that can change other users' access, and Lead can manage their MFA devices. Both warrant the tightest assignment and the most frequent review of any role in the list.
Your instance may include additional roles introduced in later releases, or roles created by your own administrators.
##  Patient groups 
Patient groups appear alongside roles in the admin console but behave differently: they carry no model permissions of their own. Their purpose is object scoping — assigning a user to a patient group determines which patients their permissions apply to.
Every instance is provisioned with an **All Patients** group. Narrower groups are created per organization to reflect panels, sites, programs, or any other division that should bound a user's reach.
##  Extending the defaults 
The default roles are a starting point, not a fixed set. Administrators with Staff Permissions Access can create additional roles, and adjust the permissions on existing ones, to match how the organization actually works. Both are done through the admin console.
When you do, a few practices keep the model reviewable:
  - Prefer creating a **new role** over broadening an existing one, so the default set stays a recognizable baseline.
  - Grant **read and write separately** where the split exists, rather than defaulting to both.
  - Scope by **patient group** wherever a user does not legitimately need the full population.
  - Review assignments to the security-sensitive roles above on a defined cadence.
##  Reviewing access 
Because permissions are held by roles rather than individuals, an access review is a review of role membership. The admin console lists the staff assigned to each role and the patient groups scoping them.
Changes to roles, permissions, and staff records are captured in the audit trail — see [Audit Logging and Telemetry](/guides/audit-logging-and-telemetry/) for what is recorded and how to export it.
> **Info:** Canvas can provide a complete role-to-model permission matrix for your instance on request, for use in a security review or access-control audit. Contact your Canvas representative.

# Creating, Implementing, and Extending an AI Scribe Parser

Source: https://docs.canvasmedical.com/guides/scribe-ai-parser/

The [AI Scribe Parser Plugin](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions/ai-scribe) was designed to help streamline clinical documentation by parsing structured transcripts into commands. With healthcare providers increasingly adopting AI-driven solutions, this guide provides developers with the insights and instructions needed to integrate and extend our example plugin to meet diverse documentation needs. In this guide, you'll learn how to:
  - Intercept [`CLIPBOARD_COMMAND__POST_INSERTED_INTO_NOTE`](/sdk/events/#clipboard-command).
  - Use `ScribeParser` (or custom parsers) to process transcripts.
  - Generate commands for each section.
  - Add or replace section parsers for custom sections.
  - Implement a fully custom parser for alternate formats.
##  Understanding the Transcript Parsing Flow. 
The workflow is triggered by pasting a transcript into a note. Doing so will automatically insert the content in the form of a clipboard command. We can then respond to that event and transform the content into the appropriate commands.
###  Input Transcript Example 
Our example transcript includes many structured sections. The sections listed below were flagged as being formatted in a way that makes them easy to translate into Canvas commands.
  - Chief complaint
  - History of present illness
  - Past medical history
  - Vitals
  - Plan
Each section contains specific information that can be parsed. For example:
  - The **Vitals** section includes data like weight, heart rate, and blood pressure, which can be converted into a `VitalsCommand`.
  - The **Assessment** section provides diagnoses and clinical impressions, which can be mapped to an `AssessCommand`.
**Complete Example**
    ```plaintext
    Chief complaint
    - Concern about potential diabetes
    - Hypertension
    History of present illness
    - Patient named Ken, age and gender not mentioned
    - Has sleep apnea, uses CPAP machine
    - Has hyperlipidemia
    - Has hypertension, on medication but doesn't remember the names
    - No other symptoms or issues reported
    - No shortness of breath or pain reported
    Past medical history
    - Sleep apnea
    - Hyperlipidemia
    - Hypertension

    - Hyperlipidemia
    - Elevated BMI, potential for weight loss intervention
    - No diabetes or prediabetes
    Plan
    - Recommendation for weight loss services
    - Recommendation to address hypertension, either at this clinic or with primary care
    - Potential adjustment of hypertension medication
    - Offered subscription program with unlimited office visits and access to a nutritionist
    - Potential telemedicine consultations due to patient's frequent travel
    Appointments
    No specific appointment made, patient to contact clinic after discussing with wife
    ICD-10 codes (3)
    - Sleep apnea, unspecified [G47.30]
    - Hyperlipidemia, unspecified [E78.5]
    - Essential (primary) hypertension [I10]
    ```
###  AI Scribe Plugin Architecture 
Once the content is pasted in, the plugin does the rest. Here's how.
####  1\. Handler Class 
The `Handler` class intercepts events and processes the transcript using a parser.
    ```python
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect
    from canvas_sdk.events import EventType
    class ScribeParser: ...  # explained in section 2 below, "ScribeParser"
    class Handler(BaseHandler):
        """A Plugin for interpreting transcripts."""
        RESPONDS_TO = EventType.Name(EventType.CLIPBOARD_COMMAND__POST_INSERTED_INTO_NOTE)
        def compute(self) -> list[Effect]:
            """Parse the transcript and generate effects to originate commands."""
            transcript = self.context["fields"]["text"]
            parser = ScribeParser()
            parsed_transcript = parser.parse(transcript, self.context)
            note_uuid = self.context["note"]["uuid"]
            effects = []
            for commands in parsed_transcript.values():
                for command in commands:
                    command.note_uuid = note_uuid
                    effects.append(command.originate(line_number=1))
            effects.reverse()
            return effects
    ```
####  2\. ScribeParser 
The `ScribeParser` delegates the parsing of each transcript section to specific section parsers.
    ```python
    from ai_scribe.parsers.base import TranscriptParser
    # explained in section 3 below, "Section Parsers"
    class ChiefComplaintParser: ...
    class HistoryOfPresentIllnessParser: ...
    class PastMedicalHistoryParser: ...
    class PlanParser: ...
    class VitalsParser: ...
    class ScribeParser(TranscriptParser):
        """A parser for scribe transcripts."""
        section_parsers = {
            "chief_complaint": ChiefComplaintParser(),
            "history_of_present_illness": HistoryOfPresentIllnessParser(),
            "past_medical_history": PastMedicalHistoryParser(),
            "vitals": VitalsParser(),
            "plan": PlanParser(),
        }
        def parse(self, transcript: str, context: dict) -> dict:
            """Parse the transcript into commands grouped by sections."""
            parsed_sections = {}
            for section, parser in self.section_parsers.items():
                parsed_sections[section] = parser.parse(transcript, context)
            return parsed_sections
    ```
####  3\. Section Parsers 
Each section parser extracts relevant information from its section and produces commands.
    ```python
    from typing import Any, Sequence
    from ai_scribe.parsers.base import CommandParser, ParsedContent
    from canvas_sdk.commands.commands.plan import PlanCommand
    class PlanParser(CommandParser):
        """Parses the plan section of a transcript."""
        def parse(self, content: ParsedContent, context: Any = None) -> Sequence[PlanCommand]:
            """Parses the plan section of a transcript."""
            return [PlanCommand(narrative=line) for line in content["arguments"]]
    ```
##  Extending the Parser 
###  1\. Adding a New Section Parser 
Suppose you want to parse the "Appointments" section into a `TaskCommand` for follow-up tasks.
####  Define the Parser 
    ```python
    from typing import Sequence, Any
    from canvas_sdk.commands import TaskCommand
    from ai_scribe.parsers.base import CommandParser, ParsedContent
    class AppointmentsParser(CommandParser):
        """Parses the 'Appointments' section of a transcript."""
        def parse(self, content: ParsedContent, context: Any = None) -> Sequence[TaskCommand]:
            """Parses the Appointments section and generates TaskCommands."""
            tasks = []
            for line in content["arguments"]:
                tasks.append(TaskCommand(title=line))
            return tasks
    ```
####  Register the Parser 
Add the `AppointmentsParser` to the `section_parsers` dictionary.
    ```python
    class AppointmentsParser: ... # defined above
    class ScribeParser:
        """A parser for transcripts."""
        section_parsers = {
            "appointments": AppointmentsParser()
        }
    ```
###  2\. Customizing the Entire Parser 
To replace `ScribeParser`, define your custom parser.
    ```python
    from ai_scribe.parsers.base import (
        ParsedContent,
        TranscriptParser,
        TranscriptParserOutput,
    )
    class CustomParser(TranscriptParser):
        """Custom parser for alternative transcript formats."""
        def parse(self, transcript: str, context: dict) -> dict:
            """Parse the transcript and produce commands."""
            # Implement custom parsing logic
            ...
    ```
Replace the parser in the `Handler` class:
    ```python
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.effects import Effect
    class CustomParser: ... # defined above
    class Handler(BaseHandler):
        """Handler using a custom parser."""
        def compute(self) -> list[Effect]:
            transcript = self.context["fields"]["text"]
            parser = CustomParser()  # Use custom parser
            parsed_transcript = parser.parse(transcript, self.context)
            note_uuid = self.context["note"]["uuid"]
            effects = []
            for commands in parsed_transcript.values():
                for command in commands:
                    command.note_uuid = note_uuid
                    effects.append(command.originate(line_number=1))
            effects.reverse()
            return effects
    ```
##  Watch the Workflow in Action 
##  Conclusion 
With robust parsing capabilities and extensibility, this example plugin equips developers to support clinicians in reclaiming their time for what matters most: patient care. By following the steps in this guide, developers can ensure seamless integration into clinical workflows, while also tailoring the tool to suit specific needs.

# How to set a default homepage for the provider application

Source: https://docs.canvasmedical.com/guides/set-default-homepage/

This guide explains how to set a default homepage for the provider application. By setting a default homepage, you can control which page users see when they first log in to the provider application, ensuring they have quick access to the most relevant information or features.
##  What you'll learn: 
  - Use the [`Application`](/sdk/data-application) model to get a specific application.
  - Use the [`DefaultHomepageEffect`](/sdk/default-homepage-effect) to set the default homepage.
##  Default homepage plugin 
####  1\. Set an application as the homepage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.default_homepage import DefaultHomepageEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from canvas_sdk.v1.data import Application
    class Homepage(BaseHandler):
        """Handler for homepage configuration events."""
        RESPONDS_TO = EventType.Name(EventType.GET_HOMEPAGE_CONFIGURATION)
        def compute(self) -> list[Effect]:
            """Set an application as the default homepage."""
            application = Application.objects.filter(name="custom_homepage").first()
            return [DefaultHomepageEffect(application_identifier=application.identifier).apply()]
    ```
####  2\. Set a specific page as the homepage 
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.default_homepage import DefaultHomepageEffect
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    class Homepage(BaseHandler):
        """Handler for homepage configuration events."""
        RESPONDS_TO = EventType.Name(EventType.GET_HOMEPAGE_CONFIGURATION)
        def compute(self) -> list[Effect]:
            """Set the Patients page as the default homepage."""
            return [DefaultHomepageEffect(page=DefaultHomepageEffect.Pages.PATIENTS).apply()]
    ```

# Staying on Top of Tasks

Source: https://docs.canvasmedical.com/guides/staying-on-top-of-tasks/

Many Canvas users work in multiple systems. If you have a system that deals with tasks that are ultimately completed in Canvas, you'll want to manage the full task lifecycle from that external system. Using Canvas' [FHIR API](/api/) and the [Canvas SDK](/sdk/), you can have your system create tasks in Canvas, and get notified when your users complete them.
![](/assets/images/guides/staying-on-top-of-tasks/flow.png)
##  Creating Tasks with the FHIR API 
Your system can originate Tasks in Canvas using our FHIR [Task Create endpoint](/api/task/#create). The id of the task you create can be found in the `location` response header. It comes back as the FHIR Task Read URL, but you can parse the id from it. See the example below. Remember, this code is hitting the Canvas API from _your_ system, not from within Canvas.
    ```python
    import requests
    import json
    payload = json.dumps({
      "resourceType": "Task",
      "status": "requested",
      "intent": "unknown",
      "description": "Send a thank you card to the office admin team.",
      "requester": {
        "reference": "Practitioner/abc123"
      }
    })
    url = "https://fumage-api-test-clinic.canvasmedical.com/Task"
    headers = {
      'Content-Type': 'application/json',
      'Authorization': 'not-a-real-token'
    }
    response = requests.request("POST", url, headers=headers, data=payload)
    # find the id of the task we just created
    task_location = response.headers['location']  # http://fumage-api-test-clinic.canvasmedical.com/Task/b6426693-eb5b-4702-9f90-4728972c7f16
    task_id = task_location.split("/Task/")[1]  # b6426693-eb5b-4702-9f90-4728972c7f16
    ```
You can then take that task id and persist it in your application for tracking its status. While some choose to poll for status changes, a better way to keep track of the state of a task is by creating a webhook. We can do that with the Canvas SDK.
##  Creating a Task completion webhook with the Canvas SDK 
> **Info:** Webhook plugins are discussed in more detail in [Creating Webhooks with the Canvas SDK](/guides/creating-webhooks-with-the-canvas-sdk/).
Implementing webhooks in a plugin gives you ultimate control over the payload and headers in your request. We use the python [requests](https://requests.readthedocs.io/en/latest/) library under the hood, so there's an extremely good chance anything you require for your request is supported.
In this example, we listen for either the `TASK_COMPLETED` or the `TASK_CLOSED` events, and send an HTTP POST with the id of the task that was either completed or closed, along with whether it was completed or closed. The target of the event is the id of the task, so the event comes with all the information we need here. You can substitute any of the Canvas SDK's supported [events](/sdk/events/) to extend this example to other record types.
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.utils import Http
    from logger import log
    class TaskResolutionWebhook(BaseHandler):
        RESPONDS_TO = [
            EventType.Name(EventType.TASK_COMPLETED),
            EventType.Name(EventType.TASK_CLOSED),
        ]
        def compute(self):
            task_disposition = 'closed'
            if self.event.type == EventType.TASK_COMPLETED:
                task_disposition = 'completed'
            url = "https://webhook.site/ee7aed78-b652-4d9e-b858-04465c409d15"
            payload = {
                "task_id": self.target,
                "disposition": task_disposition,
            }
            http = Http()
            response = http.post(url, json=payload)
            if response.ok:
                log.info("Successfully notified API of task update!")
            else:
                log.info("Notification unsuccessful. =[")
            return []
    ```
Once installed, the url you specified in the code will receive an HTTP POST request whenever a user marks a task as completed or closed. Your application can listen for those requests and update your internal status of that task.

# Submit a Full Vital Panel through Canvas FHIR API

Source: https://docs.canvasmedical.com/guides/submit-vitals-via-fhir/

Inside of the Canvas' [Vital Command](https://canvas-medical.help.usepylon.com/articles/9426091672-command-vitals) there are many vital signs supported to document.
![Protocol framework](/assets/images/vitals/vital-empty.png)
The Canvas [FHIR Observation Create](/api/observation/#create) endpoint supports writing some of the vital signs in the command. This guide will show you all the vitals that can be documented in the Create interaction.
* * *
##  What you'll learn 
In this guide, you will learn how to do the following:
  1. Create a vital panel via FHIR
  2. Submit various vital signs into the same panel via FHIR
  3. Perform a FHIR Observation Search to view the completed panel
* * *
###  1\. Setup and Authentication 
This guide will demonstrate many FHIR API calls into Canvas. Before we can make a FHIR request, we need to setup some imports, reusable variables, and authenticate into the instance we want to work with.
Here is your starting point:
    ```python
    import requests
    url = "https://fumage-example.canvasmedical.com/Observation"
    headers = {
        "accept": "application/json",
        "Authorization": "Bearer <token>",
        "content-type": "application/json"
    }
    ```
But there are two places above to update:
  1. The `url` will show `https://fumage-example.canvasmedical.com/Observation`. You will need to replace `example` with the name of the Canvas instance you are using.
  2. One of the `header` elements will be `'Authorization': 'Bearer <token>'`. You will need to create this `<token>` following our steps laid out in [Customer Authentication](/api/customer-authentication)
###  2\. Understanding our Observation Payload 
Before we start creating the vital panel and the associated vital signs, take some time to familiarize yourself with the [FHIR Observation Create](/api/observation/#create) endpoint. Each payload to create an observation requires `status`, `code`, and `subject`.
In this guide the `status` will always be `final` and the `subject` will always appear as:   
`"subject": { "reference": "Patient/$patient_id" }`.  
When completing these steps yourself, you will want to change the `{patient_id}` to match a patient in the instance you are using (e.g `"Patient/ee8672f3497e4a83937b9e71d0a704a5"`).
The `code` attribute is the real magic that tells Canvas which vital you are creating. The coding will always be a LOINC code.
Another thing to note is an optional `effectiveDateTime` attribute. This allows you to specify the time the vital was taken. But if omitted, it will default to the time of creation.
###  3\. Create a Vital Panel 
First we will need to create the panel object to be able to save all the individual vital signs to. The important attribute is the `code.coding[0][code]` being `85353-1` to represent a vital panel.
Here is the payload for how to create a Vital Panel (remember to set the patient_id and also update the effectiveDateTime):
    ```python
    import requests
    url = "https://fumage-example.canvasmedical.com/Observation"
    headers = {
        "accept": "application/json",
        "Authorization": "Bearer <token>",
        "content-type": "application/json"
    }
    patient_id = "<a patient ID from your instance>"
    payload = {
        "resourceType": "Observation",
        "status": "final",
        "code": {
            "coding": [
                {
                    "system": "http://loinc.org",
                    "code": "85353-1",
                    "display": "Vital Panel"
                }
            ]
        },
        "subject": {
            "reference": f"Patient/{patient_id}"
        },
        "effectiveDateTime": "2024-03-29T08:50:24.883809+00:00"
    }
    response = requests.post(url, json=payload, headers=headers)
    ```
On a successful create, when the `response.status_code` equal 201. We can fetch the ID of the newly created observation in the `response.headers['location']` attribute. The value will always be in the format `{url}/{id}/_history/1`. We need to extract the `id` from the value.
However, if the request failed it will throw an error to see what went wrong. It will also display the Correlation ID that can be given to Customer Support for help with further debugging.
    ```python
    if response.status_code == 201:
        panel_id = response.headers['location'].replace(f"{url.replace('https', 'http')}/", '').replace('/_history/1', '')
    else:
        raise Exception(f"Failed to perform {response.url}. \n Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
Looking in the Canvas UI, there will now be a Data Import note placed on that patient's timeline based on the date passed in the `effectiveDateTime` attribute with an empty Vitals Command:
![Protocol framework](/assets/images/vitals/vital-panel-in-import-note.png)
###  4\. Creating Individual Vital Signs 
Now that we have created a Vital Panel, we will be able to use this panel_id when creating the individual vital signs to be associated with the same command by passing the `derivedFrom` attribute in the payload:
    ```python
    payload = {
        # ...
        "derivedFrom": [
            {
                "reference": f"Observation/{panel_id}",
                "type": "Observation"
            }
        ],
        # ...
    }
    ```
Now we are ready to create the following vital signs in the panel that are supported via FHIR Observation Create:
  - Height
  - Weight
  - Waist Circumference
  - Body Temperature
  - Blood Pressure
  - Pulse Rhythm
  - Pulse Rate
  - Respiration Rate
  - Oxygen Saturation
  - Notes
####  Add Height 
Height is denoted by the LOINC code `8302-2`. Since its value is numeric, we will be able to pass the value and units through the `valueQuantity` attribute. By default if no `valueQuantity.unit` is specified, it will default to using inches, but `cm` is also supported, it will just convert it to inches on the UI and when a Read/Search is performed.
Here is a payload to create a height of 69.0 inches:
    ```python
    payload = {
        "resourceType": "Observation",
        "status": "final",
        "code": {
            "coding": [
                {
                    "system": "http://loinc.org",
                    "code": "8302-2",
                    "display": "Height"
                }
            ]

    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
Looking in the Canvas UI, there will now be height of `69.0 in` added in that Vitals Command:

####  Add Weight 
Weight is denoted by the LOINC code `29463-7`. Since its value is numeric, we will be able to pass the value and units through the `valueQuantity` attribute. By default if no `valueQuantity.unit` is specified, it will default to using ounces, but `lb` or `kg` is also supported, it will just convert it to `oz` when a Read/Search is performed. The UI will display it in `lbs` and leftover `oz`.
Here is a payload to create a weight of 176.4 lbs:
    ```python
    payload = {
        "resourceType": "Observation",
        "status": "final",
        "code": {
            "coding": [

                    "display": "Weight"
                }
            ]
        },

            }
        ]
    }
    response = requests.post(url, json=payload, headers=headers)
    if response.status_code == 201:
        print(f"Weight observation id = {response.headers['location'].replace(f'{url}/', '').replace('/_history/1', '')}")
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
Looking in the Canvas UI, there will now be weight of `176 lbs 6.4 oz` added in that Vitals Command:
![Protocol framework](/assets/images/vitals/weight.png)
####  Add Waist Circumference 
Waist Circumference is denoted by the LOINC code `29463-7`. Since its value is numeric, we will be able to pass the value and units through the `valueQuantity` attribute. By default if no `valueQuantity.unit` is specified, it will default to using centimeters, but `in` is also supported, it will just convert it to `cm` on the UI or when a Read/Search is performed.
Here is a payload to create a waist circumference of `98.2 cm`:
    ```python
    payload = {
        "resourceType": "Observation",
        "status": "final",
        "code": {
            "coding": [

        ]
    }
    response = requests.post(url, json=payload, headers=headers)
    if response.status_code == 201:
        print(f"Waist Circumference observation id = {response.headers['location'].replace(f'{url}/', '').replace('/_history/1', '')}")
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```

####  Add Body Temperature 
Body Temperature is denoted by the LOINC code `8310-5`. Since its value is numeric, we will be able to pass the value and units through the `valueQuantity` attribute. The only unit accepted for body temperature is `°F` and if omitted it will be default.
Here is a payload to create a temperature of `98.4 °F`:
    ```python
    payload = {
        "resourceType": "Observation",
        "status": "final",
        "code": {
            "coding": [

    response = requests.post(url, json=payload, headers=headers)
    if response.status_code == 201:
        print(f"Body Temperature observation id = {response.headers['location'].replace(f'{url}/', '').replace('/_history/1', '')}")
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
Looking in the Canvas UI, there will now be temperature of `98.4 °F` added in that Vitals Command:
![Protocol framework](/assets/images/vitals/body-temperature.png)
####  Add Blood Pressure 
Blood Pressure is denoted by the LOINC code `85354-9`. In the Vital's command blood pressure is a string value that combines the systolic and diastolic components with a `/`. So the payload will pass the `valueString` component in order for the blood pressure to appear correctly in the Vitals Command.
Since blood pressure is made up of two values, the payload will also define a `component` attribute list to pass the systolic (LOINC code `8480-6`) and diastolic (LOINC code `8462-4`) values. These two values are numeric, so they will have the `valueQuantity` attributes where the unit will be `mmHg`
Here is a payload to create a Blood Pressure of `122/68`:
    ```python
    payload = {
        "resourceType": "Observation",

####  Add Oxygen Saturation 
Oxygen Saturation is denoted by either LOINC code `2708-6` or `59408-5`. Canvas saves the oxygen saturation with both codings. Since its value is numeric, we will be able to pass the value and units through the `valueQuantity` attribute. The only unit accepted for Oxygen Saturation is `%` and if omitted it will be default.
Here is a payload to create a Oxygen Saturation of `98%`:

    response = requests.post(url, json=payload, headers=headers)
    if response.status_code == 201:
        print(f"Oxygen Saturation observation id = {response.headers['location'].replace(f'{url}/', '').replace('/_history/1', '')}")
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")

Looking in the Canvas UI, there will now will be a Note added in that Vitals Command:

###  5\. Perform FHIR Observation Read and Search 
A full Vital Panel has been completed! Let's now perform a FHIR Observation Read using the `panel_id` to see all the observation members of this panel now:
    ```python
    from pprint import pprint
    response = requests.get(f"{url}/{panel_id}", headers=headers)
    if response.status_code == 200:
        pprint(response.json())
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
The output will look like:
    ```json

    ```
And finally let's perform a FHIR Observation Search to see all the vital signs that are for that patient using the derived from search parameter:
    ```python
    from pprint import pprint
    response = requests.get(f"{url}?patient=Patient/{patient_id}&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&derived-from=Observation/{panel_id}&_count=20", headers=headers)
    if response.status_code == 200:
        pprint(response.json())
    else:
        raise Exception(f"Failed to perform {response.url}. \n Fumage Correlation ID: {response.headers['fumage-correlation-id']} \n {response.text}")
    ```
The response will look like:
    ```json

        "type": "searchset",
        "total": 10,

# Tailoring the Chart to the Patient

Source: https://docs.canvasmedical.com/guides/tailoring-the-chart-to-the-patient/

Different patients have different needs, and your tools should reflect that. EMRs are able to be used in a wide variety of scenarios. In order to be able to do just about anything, your EMR is packed to the gills with features and options. While you might need all of these features for all of your patients, you almost certainly don't need _every_ feature for _each_ of your patients.
This guide shows a few examples of using a patient's data to customize their chart so the EMR features most relevant to them are front-and-center, while minimizing or hiding what you don't need in the moment. Tailoring the interface based on the patient in front of you creates a focused environment for you to deliver care without irrelevant options getting between you and your patient.
> **Info:** This guide assumes pre-existing knowledge of the Canvas SDK. If you're starting from scratch, you may want to read and implement [Your First Plugin (with Claude Code)](/guides/your-first-plugin-with-claude-code/) before working through this exercise.
##  Chart Customizations for Pediatric Patients 
We will make two simple changes to the charting interface when the selected patient is a child:
  1. Move the Immunization list to the top of the patient summary
  2. Prevent adult-only diagnosis choices from appearing in searches
First, we'll need to initialize a new plugin.
The Canvas CLI gives you a great head start when creating a plugin. Simply run `canvas init`, and answer the prompt to name your plugin.
    ```sh
    $ canvas init
      [1/1] project_name (My Cool Plugin): Pediatric Patient Chart Customizations
    Project created in /Users/andrew/src/canvas-plugins/pediatric-patient-chart-customizations
    ```
This output shows the location of our freshly generated plugin project. In this directory, you'll see a default class (`pediatric_patient_chart_customizations/handlers/event_handlers.py`) provided as a starting point for your code.
    ```sh
    $ tree pediatric_patient_chart_customizations/
    pediatric_patient_chart_customizations/
    ├── CANVAS_MANIFEST.json
    ├── README.md
    └── handlers
        ├── __init__.py
        └── event_handlers.py
    2 directories, 4 files
    ```
You can use this file as a starting point, or you can start fresh with a new file. At minimum, I recommend renaming `event_handlers.py` to something more descriptive, and you'll need to update the references to the file in `CANVAS_MANIFEST.json` as well.
###  Move Immunizations to the Top of the Patient Summary 
I've created a new file, `handlers/pediatric_chart_layout.py`, and I've updated my `CANVAS_MANIFEST.json` to reflect it.
    ```sh
    $ tree pediatric_patient_chart_customizations/
    pediatric_patient_chart_customizations/
    ├── CANVAS_MANIFEST.json
    ├── README.md
    └── handlers
        ├── __init__.py
        └── pediatric_chart_layout.py
    2 directories, 4 files
    ```
Here is a pretty empty class with some comments that will guide our development:
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    class PediatricChartLayout(BaseHandler):
        """
        This event handler rearranges the patient summary section to focus on the
        parts most relevant to pediatric patients when it detects that the patient
        for the current chart is <= 17 years old.
        """
        # This event fires when a patient chart's summary section is loading.
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)
        def compute(self):
            """
            Check to see if the patient is <= 17 years old. If so, move their
            immunization list to the top of the patient summary.
            """
            # Look up the patient whose chart is being loaded right now
            # See if the patient is younger than 18 years old
            # If they are not younger than 18, do nothing
            # If they are younger than 18, re-arrange the layout of their summary
            # sections to put immunizations at the top.
            # BaseHandler subclasses must return a list, but it can be empty. It
            # is empty here since we aren't doing anything just yet.
            return []
    ```
Pretty straightforward logic. Do nothing or do something based on their age.
####  Looking Up the Patient 
In order to determine if we are on a pediatric chart, we'll need to know the patient and their birth date. We can use the [Patient class](/sdk/data-patient/) in the [Data Module](/sdk/data/) for this.
The `PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION` event is accompanied by the id of the patient whose chart is being loaded. You can find it using `self.target`. The patient is the target of the event.
    ```python
    import arrow
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.v1.data.patient import Patient
    class PediatricChartLayout(BaseHandler):
        """
        This event handler rearranges the patient summary section to focus on the
        parts most relevant to pediatric patients when it detects that the patient
        for the current chart is <= 17 years old.
        """
        # This event fires when a patient chart's summary section is loading.
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)
        def compute(self):
            """
            Check to see if the patient is <= 17 years old. If so, move their
            immunization list to the top of the patient summary.
            """
            eighteen_years_ago = arrow.now().shift(years=-18).date().isoformat()
            patient_is_pediatric = Patient.objects.filter(
                id=self.target, birth_date__gt=eighteen_years_ago).exists()
            # If the patient is not pediatric, do not alter the layout.
            if not patient_is_pediatric:
                return []
            # TODO: Alter the layout
            return []
    ```
In the code above, you'll see I didn't actually retrieve the patient's information. Since I don't plan to use any of the data from the patient record, I instead let the database answer the question: "Does the patient with this id have a birth date more recent than 18 years ago?" This is a performance optimization. The less data transmitted, the faster your plugins execute, and the faster your charts load. This is not strictly necessary, but over time and with enough plugins installed the inefficiencies could add up. If you'd like you could alternately retrieve the patient and make a direct comparison to their `birth_date` attribute.
####  Altering the Layout 
When loading the patient's summary, the front-end consults a list of sections to retrieve data for and render. Our plugin influences this list, and it does so using the [`PatientChartSummaryConfiguration`](https://github.com/canvas-medical/canvas-plugins/blob/main/canvas_sdk/effects/patient_chart_summary_configuration.py) effect. Using the list of possible sections, we construct the ordered list of sections we want to see. In this example we're just moving one to the top, but you could also omit sections to hide them entirely if there are sections you do not use or need for your [Care Model](https://www.canvasmedical.com/articles/care-modeling-the-secret-to-success-in-care-delivery).
    ```python
    import arrow
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    from canvas_sdk.effects.patient_chart_summary_configuration import PatientChartSummaryConfiguration
    from canvas_sdk.v1.data.patient import Patient
    class PediatricChartLayout(BaseHandler):
        """
        This event handler rearranges the patient summary section to focus on the
        parts most relevant to pediatric patients when it detects that the patient
        for the current chart is <= 17 years old.
        """
        # This event fires when a patient chart's summary section is loading.
        RESPONDS_TO = EventType.Name(EventType.PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION)
        def compute(self):
            """
            Check to see if the patient is <= 17 years old. If so, move their
            immunization list to the top of the patient summary.
            """
            eighteen_years_ago = arrow.now().shift(years=-18).date().isoformat()
            patient_is_pediatric = Patient.objects.filter(
                id=self.target, birth_date__gt=eighteen_years_ago).exists()
            # If the patient is not pediatric, do not alter the layout.
            if not patient_is_pediatric:
                return []
            layout = PatientChartSummaryConfiguration(sections=[
              PatientChartSummaryConfiguration.Section.IMMUNIZATIONS,
              PatientChartSummaryConfiguration.Section.SOCIAL_DETERMINANTS,
              PatientChartSummaryConfiguration.Section.GOALS,
              PatientChartSummaryConfiguration.Section.CONDITIONS,
              PatientChartSummaryConfiguration.Section.MEDICATIONS,
              PatientChartSummaryConfiguration.Section.ALLERGIES,
              PatientChartSummaryConfiguration.Section.CARE_TEAMS,
              PatientChartSummaryConfiguration.Section.VITALS,
              PatientChartSummaryConfiguration.Section.SURGICAL_HISTORY,
              PatientChartSummaryConfiguration.Section.FAMILY_HISTORY,
            ])
            return [layout.apply()]
    ```
Once installed, pediatric patients will have their immunization section at the top of their summary, while adult patients will continue to have social determinants as their initial section.
###  Prevent adult-only diagnosis choices from appearing in searches 
Some diagnosis codes are restricted to adult patients. CMS provides a [list](https://www.cms.gov/Medicare/Coding/OutpatientCodeEdit/Downloads/ICD-10-IOCE-Code-Lists.pdf) of these "Adult Diagnoses". We can reference this list and filter them out of the diagnosis search results for pediatric patients. This increases the quality of your search and makes it easier for you to find the right choice.
I've created a new file, `handlers/pediatric_condition_search.py`, and I've updated my `CANVAS_MANIFEST.json` to reflect it.
Here's the updated plugin file structure:
    ```sh
    $ tree pediatric_patient_chart_customizations/
    pediatric_patient_chart_customizations/
    ├── CANVAS_MANIFEST.json
    ├── README.md
    └── handlers
        ├── __init__.py
        ├── pediatric_chart_layout.py
        └── pediatric_condition_search.py
    2 directories, 5 files
    ```
And here's the updated `CANVAS_MANIFEST.json`:
    ```json

                    }
                },
                {
                    "class": "pediatric_patient_chart_customizations.handlers.pediatric_condition_search:PediatricConditionSearch",

                    }

            # list.
            return []
    ```
Using the list provided by CMS, we can create a set of ICD-10 codes that should be restricted to adults. According to CMS, these diagnoses are only relevant to patients 15 or older.
While the layout altering class responded to a single event, we're listening for two different events here: diagnose command search and past medical history command search. Both of these commands include a diagnosis code search box, so we'll want to affect both. We wouldn't want to impact a family history command diagnosis search, since the family members recorded there are often adults.
####  Looking Up the Patient 
In the previous example, the target of the `PATIENT_CHART_SUMMARY__SECTION_CONFIGURATION` event was the patient. For the events we're responding to here, the target is the [command](/sdk/data-command/) that the search is occurring within. In order to determine if the patient is young enough for our code to be invoked, we'll first look up the patient's id from the command, then assess their age in a similar manner as before.
    ```python
    import arrow
    from canvas_sdk.v1.data.command import Command
    from canvas_sdk.v1.data.patient import Patient
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers.base import BaseHandler
    ADULT_ONLY_ICD_CODES = {
        # There are many, many more. Limiting this example for brevity.
        # ...
        "Z561",   # Change of job
        "Z5682",  # Military deployment status
        # ...
    }
    class PediatricConditionSearch(BaseHandler):
        """
        Filter condition searches for pediatric patients.
        """
        RESPONDS_TO = [
            EventType.Name(EventType.DIAGNOSE__DIAGNOSE__POST_SEARCH),
            EventType.Name(EventType.MEDICAL_HISTORY__PAST_MEDICAL_HISTORY__POST_SEARCH),
        ]
        def compute(self):
            """
            Remove condition search results representing codings that are resevered
            for adults if the patient is <= 15 years old.
            """
            # This event's target is the command we are searching within. Look up
            # the patient id from the command.
            patient_id = Command.objects.filter(id=self.target).values_list('patient__id', flat=True).first()
            fifteen_years_ago = arrow.now().shift(years=-15).date().isoformat()
            patient_is_pediatric = Patient.objects.filter(
                id=patient_id, birth_date__gt=fifteen_years_ago).exists()
            # If the patient is not pediatric, do not alter the search.
            # If the patient is pediatric, loop through the search results, and
            # compare the codings of the options with our list of adult-only
            # diagnosis codes. If it's an adult only code, remove it from the
            # list.
            return []
    ```
Once again you see some code that optimizes for performance over readability. If you're not familiar with the Django ORM, this code:
    ```python
    patient_id = Command.objects.filter(id=self.target).values_list('patient__id', flat=True).first()
    ```
Is equivalent to this code, which you may find more readable:
    ```python
    command = Command.objects.get(id=self.target)
    patient_id = command.patient.id
    ```
However you get to the patient's id is up to you. Once you have it, the code is nearly identical to the previous example, the only difference being the age we're targeting. We are asking the database "Does the patient with this id have a birth date more recent than 15 years ago?"
####  Altering the Layout 
Now that we know when we should act, we need to write the code for filtering the list of search results. When the search is performed, the raw results are sent to our code before being ultimately delivered to the dropdown box in the front-end. We have the opportunity to modify that list before it hits the dropdown. While we're focused on removing irrelevant choices, you could also add labels to certain ones you wish to highlight or alter the search order to guide users to preferred options.
Our code loops through the ICD-10 codes associated with the search results, checks for their presence in the set of adult ICD-10 codes, and only includes them in the post-processed set if they are not in the adult code list. The raw search results are in the event's context object under the `results` key.
Here's the full code:
    ```python
    import json
    import arrow
    from canvas_sdk.v1.data.command import Command

        # ...
    }

            for result in self.context["results"]:
                for coding in result.get("extra", {}).get("coding", []):
                    if not coding.get("system") in ("http://hl7.org/fhir/sid/icd-10", "ICD-10"):
                        continue
                    # If the ICD 10 code is not in the list of Adult-only codes,
                    # we can add this result to what will ultimately be returned.
                    if coding.get("code") not in ADULT_ONLY_ICD_CODES:
                        post_processed_results.append(result)
                        break
            # Return our modified search results
            return [

                    payload=json.dumps(post_processed_results),
                )
            ]
    ```
Once installed, certain diagnosis codes will not clutter up search results in commands for pediatric patients, but will continue to show as expected for patients over the age of 15.
##  Watch the Workflow in Action 
View and deploy the Pediatric Patient Chart Customization Extension [here](https://www.canvasmedical.com/extensions/pediatric-patient-chart-customizations).
##  Conclusion 
Age is one differentiator that changes the relevance of EMR features, but there are many, many others. Using the Canvas SDK can help keep clinicians focused, with the features they need front-and-center and the ones they don't need out of the way.

# Using AttributeHubs for Plugin State

Source: https://docs.canvasmedical.com/guides/using-attribute-hubs-for-plugin-state/

Plugins that run on a schedule often need to remember where they left off. A lab sync needs a cursor so it doesn't re-fetch results. A reminder system needs to track which patients have already been contacted. A data pipeline needs a lock so overlapping runs don't collide.
[AttributeHubs](/sdk/custom-data-attribute-hubs/) are a natural fit for this kind of state. A single hub can hold a mix of strings, numbers, booleans, timestamps, and JSON structures — no schema definition required. In this guide you'll build a plugin that periodically syncs lab results from an external vendor and uses one AttributeHub to manage its sync cursor, run lock, configuration, and operational statistics.
> **Info:** This guide assumes you have the Canvas CLI installed and configured, and that you're familiar with plugin basics. If you're starting from scratch, work through [Your First Plugin](/guides/your-first-plugin/) first.
##  What we're building 
The plugin has two components:
  1. **A cron handler** that runs every 10 minutes and processes a batch of lab results. This guide uses generated demo data so you can deploy it immediately and see it work. In production, you'd swap in a real API call to your lab vendor — only the `fetch_results` method changes.
  2. **A single AttributeHub** that stores all of the sync state: cursor position, run lock, processing stats, and a mapping of the vendor's test codes to LOINC codes.
The hub demonstrates several AttributeHub value types working together:
Attribute| Type| Purpose  
---|---|---  
`last_sync_cursor`| datetime| Timestamp of the most recent result fetched  
`is_running`| boolean| Lock flag to prevent overlapping runs  
`last_run_at`| datetime| When the sync last completed  
`results_synced`| integer| Running total of results processed  
`batch_size`| integer| How many results to pull per run  
`code_mapping`| JSON (dict)| Vendor test codes → LOINC codes  
`failed_accessions`| JSON (list)| Accession numbers that failed processing  
##  Initialize the plugin 
    ```sh
    $ canvas init
      [1/1] project_name (My Cool Plugin): Lab Sync
    Project created in /Users/you/lab-sync
    ```
    ```sh
    cd lab-sync
    ```
Remove the placeholder handler since we'll create our own:
    ```sh
    rm lab_sync/handlers/event_handlers.py
    ```
##  Configure the manifest 
Replace the contents of `lab_sync/CANVAS_MANIFEST.json`:
    ```json
    {
        "sdk_version": "0.1.4",
        "plugin_version": "0.0.1",
        "name": "lab_sync",
        "description": "Syncs lab results from an external vendor on a schedule",
        "components": {
            "handlers": [
                {
                    "class": "lab_sync.handlers.sync_labs:SyncLabs",
                    "description": "Cron job that pulls lab results from an external vendor"
                }
            ]
        },
        "variables": [],
        "custom_data": {
            "namespace": "my_org__lab_sync",
            "access": "read_write"
        },
        "tags": {},
        "license": "",
        "readme": "./README.md"
    }
    ```
Replace `my_org` in the namespace with your organization's name.
##  Build the sync handler 
Create `lab_sync/handlers/sync_labs.py`. This version uses generated demo data so you can install it and see every code path exercised immediately. The `fetch_results` method is the only part you'd replace with a real API call in production — everything else stays the same.

                f"{synced_count} total synced, {len(failed)} failed"
            )
    ```
##  Anatomy of the plugin 
###  State initialization 
The `get_sync_state` function uses `get_or_create` to ensure the state hub exists. On first run, it seeds the hub with default values:
    ```python
    hub, created = AttributeHub.objects.get_or_create(
        type="lab_sync_state",
        id="singleton",
    )
    if created:
        hub.set_attributes({
            "is_running": False,
            "results_synced": 0,
            "batch_size": 50,
            "code_mapping": DEFAULT_CODE_MAPPING,
            "failed_accessions": [],
        })
    ```
Because this plugin only needs one state hub, we use the fixed id `"singleton"`. The `type` and `id` together form a unique key, so every invocation loads the same hub.
Notice the variety of types in one hub: a boolean lock, integer counters and configuration, a dict for code mappings, and a list for tracking failures. Timestamp attributes like `last_sync_cursor` and `last_run_at` start as `None` (unset) and are populated with `datetime` objects once the first run completes. `set_attributes` maps each Python type to the appropriate database column automatically.
###  Run lock 
The `is_running` boolean prevents overlapping syncs. Since the cron runs every 10 minutes, a slow API response could cause the next invocation to start before the previous one finishes. The lock pattern is straightforward:
    ```python
    if hub.get_attribute("is_running"):
        log.info("Lab sync already in progress, skipping")
        return []
    hub.set_attribute("is_running", True)
    try:
        # ... do work ...
    finally:
        hub.set_attributes({
            "is_running": False,
            "last_run_at": datetime.fromisoformat(self.target),
        })
    ```
The `finally` block ensures the lock is released even if processing raises an exception. Without it, a crash would leave `is_running` as `True` permanently, and the sync would never run again. Note that `self.target` is an ISO 8601 string, so we parse it into a `datetime` before storing it — this way AttributeHub stores it in the `timestamp_value` column rather than as text.
###  Cursor-based pagination 
Each run picks up where the last one left off by reading `last_sync_cursor`. In a production plugin, this cursor would be sent to the vendor API so it only returns newer results. After processing a batch, the cursor advances to the timestamp of the most recent result:
    ```python
    cursor = hub.get_attribute("last_sync_cursor") or ""
    # ... fetch and process results ...
    hub.set_attribute("last_sync_cursor", latest_cursor)
    ```
On the very first run, the cursor is an empty string. Each subsequent run advances the cursor to the most recent result's timestamp, so a real vendor API call would only return results newer than the cursor.
###  Code mapping as JSON 
The `code_mapping` attribute is a Python dict stored as JSON in the database. It maps the vendor's proprietary test codes to standard LOINC codes:
    ```python
    code_mapping = hub.get_attribute("code_mapping") or {}
    # ...
    loinc_code = code_mapping.get(vendor_code)
    ```
This mapping doesn't belong in a CustomModel column because its keys vary by vendor. A different lab system would have entirely different test codes. Storing it as a JSON attribute means the mapping can be updated at runtime — for example, through a separate admin API endpoint — without any schema changes.
###  Failure tracking 
Failed accession numbers accumulate in the `failed_accessions` list attribute. This gives operators visibility into which results couldn't be processed, without building a separate error-tracking table:
    ```python
    failed = hub.get_attribute("failed_accessions") or []
    # ...
    failed.append(accession)
    # ...
    hub.set_attribute("failed_accessions", failed)
    ```
In a production plugin you might periodically clear this list after the failures have been investigated, or cap its length to prevent unbounded growth.
##  Install and test 
Install the plugin:
    ```sh
    canvas install lab-sync --host YOUR_INSTANCE
    ```
Stream the logs to watch the sync run:
    ```sh
    canvas logs --host YOUR_INSTANCE
    ```
Within 10 minutes you should see the first run initialize the state hub and process the demo batch:
    ```text
    INFO Initialized lab sync state hub with defaults
    INFO Processed result DEMO-0001: CBC → 58410-2
    INFO Processed result DEMO-0002: HBA1C → 4548-4
    INFO No LOINC mapping for vendor code 'UNKNOWN_PANEL' (accession DEMO-0003), skipping
    INFO Lab sync complete: 3 fetched, 2 total synced, 1 failed
    ```
The first two results mapped successfully. The third — `UNKNOWN_PANEL` — had no entry in `code_mapping`, so it was added to the `failed_accessions` list. On the next run, the demo cycles to different test codes and the accession numbers continue incrementing, so you can watch the cursor, counters, and failure list evolve over successive runs.
##  Inspecting and updating state 
Because all sync state lives in a single AttributeHub, you can inspect or adjust it through a SimpleAPI endpoint or a plugin-based application. For example, to reset the cursor and re-sync from scratch:
    ```python
    hub = AttributeHub.objects.get(type="lab_sync_state", id="singleton")
    hub.set_attributes({
        "last_sync_cursor": "",
        "results_synced": 0,
        "failed_accessions": [],
    })
    ```
To add a new code mapping without redeploying:
    ```python
    hub = AttributeHub.objects.get(type="lab_sync_state", id="singleton")
    mapping = hub.get_attribute("code_mapping")
    mapping["VITAMIN_D"] = "1989-3"
    hub.set_attribute("code_mapping", mapping)
    ```
This is one of the practical benefits of storing configuration as AttributeHub attributes — it's data you can change at runtime, not code you have to redeploy.
##  Connecting to a real vendor 
To swap the demo data for a real lab vendor API, replace `fetch_results` with an HTTP call using `canvas_sdk.utils.Http`. The rest of the plugin stays exactly the same.
    ```python
    from canvas_sdk.utils import Http
    def fetch_results(self, hub):
        """Pull a batch of results from the vendor API."""
        base_url = self.secrets["LAB_VENDOR_BASE_URL"]
        api_key = self.secrets["LAB_VENDOR_API_KEY"]
        cursor = hub.get_attribute("last_sync_cursor") or ""
        batch_size = hub.get_attribute("batch_size")
        http = Http()
        response = http.get(
            f"{base_url}/results",
            headers={
                "Authorization": f"Bearer {api_key}",
                "X-Since": cursor,
                "X-Limit": str(batch_size),
            },
        )
        if not response.ok:
            log.info(
                f"Lab vendor API returned {response.status_code}, "
                f"skipping this run"
            )
            return []
        return response.json().get("results", [])
    ```
You'll also need to add the secrets to your manifest and configure them at install time:
    ```json
    "variables": [
        {"name": "LAB_VENDOR_API_KEY", "sensitive": true},
        {"name": "LAB_VENDOR_BASE_URL", "sensitive": false}
    ],
    ```
    ```sh
    canvas install lab-sync \
        --host YOUR_INSTANCE \
        --secret LAB_VENDOR_API_KEY=your-api-key \
        --secret LAB_VENDOR_BASE_URL=https://api.labvendor.example.com/v1
    ```
The vendor's response must include a `results` array of objects with at minimum `accession_number`, `test_code`, and `collected_at` fields to match what `process_results` expects.
##  When to use a CustomModel instead 
A single state hub works well when your plugin manages a handful of values that are read and written as a group. Consider switching to [CustomModels](/sdk/custom-data-custom-models/) when:
  - You need to **store one record per entity** (e.g., sync status per patient). A separate hub per patient works up to a point, but a CustomModel with a foreign key to Patient gives you proper relationships and efficient queries.
  - You need to **query by attribute value** across many records. Finding all hubs where `results_synced > 100` requires a JOIN to the attribute table per condition. A CustomModel with an indexed integer column handles this natively.
  - Your **state has grown into a stable schema**. If you find yourself always reading and writing the same set of attributes, that's a sign the data has matured into a schema worth formalizing.
For a deeper comparison, see [Design Considerations](/sdk/custom-data-design-considerations/).

# Writing Commands Over HTTP

Source: https://docs.canvasmedical.com/guides/writing-commands-over-http/

Writing to a patient's chart from outside Canvas — from a custom charting surface, a scribe, an intake form, a back-office tool — used to mean building the API yourself: a [SimpleAPI](/sdk/handlers-simple-api/) route per command, reading a JSON body, mapping keys onto command fields, deciding what a bad value returns, building the effect. Every team that needed it built the same one.
**Canvas has now built it for you.** `CommandAPI` is that endpoint, templated: it reads the body onto a command, validates it against that command, and emits the effects. All you add is the part that should be yours — who may call it, and what they are allowed to write.
That remainder is most of this guide, because it is the part no template can decide: authentication tells you _who_ is calling, not whether that person may write to _this note_.
##  What you'll learn 
  - How to expose one command as an HTTP endpoint with [`CommandAPI`](/sdk/handlers-simple-api-commands/)
  - The request and response shape every operation shares
  - How to check that the caller may actually write to _this note_ , which authentication alone does not tell you
  - How to serve every command from a single endpoint
##  Your first command endpoint 
`CommandAPI` is a `SimpleAPI`, so it brings the request handling. You declare a scheme, a prefix and your routes — here a staff session guards the endpoint, and one `POST` writes a History of Present Illness. Which scheme to use is a decision of its own:
    ```python
    from canvas_sdk.commands import HistoryOfPresentIllnessCommand
    from canvas_sdk.commands.api import CommandAPI
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, api
    class HistoryOfPresentIllnessAPI(StaffSessionAuthMixin, CommandAPI):
        PREFIX = "/v1"
        @api.post("/hpi")
        def insert(self) -> list[Response | Effect]:
            return self.originate(HistoryOfPresentIllnessCommand)
        @api.patch("/hpi/<command_id>")
        def update(self) -> list[Response | Effect]:
            return self.edit(HistoryOfPresentIllnessCommand, self.request.path_params["command_id"])
        @api.delete("/hpi/<command_id>")
        def remove(self) -> list[Response | Effect]:
            return self.action(
                HistoryOfPresentIllnessCommand, self.request.path_params["command_id"], "delete"
            )
    ```
That is the whole endpoint. Posting to it:
    ```sh
    curl -X POST "https://example.canvasmedical.com/plugin-io/api/my_plugin/v1/hpi" \
      -H "Content-Type: application/json" \
      -d '{
            "note_id": "fd05f99a-7abe-4bcd-be94-adf09937af2a",
            "values": {"narrative": "Patient reports a headache for three days."}
          }'
    ```
    ```json
    { "command_uuid": "2588aa22-f5b4-4335-b4fe-aea69cdfb3f3", "committed": false }
    ```
> **Warning:** A route handler cannot be named `originate`, `edit` or `action` — those are the methods you are calling. Name handlers for the HTTP verb they serve, as above.
##  The three operations 
Everything `CommandAPI` does is one of three calls, and between them they cover the life of a command: `originate` puts a new one in a note, `edit` revises it while it is still staged, and `action` runs whatever finishes it — committing it, sending it, or entering it in error. Each returns the effects and the response together, so a route handler stays a single `return`.
The body each call accepts, the status it answers with, and every error shape are documented in [Commands API](/sdk/handlers-simple-api-commands/#methods). What is left to you is a handful of decisions no reference can make:
**Staged, or committed in the same request.** `originate` leaves the command staged unless you ask otherwise. Staged is usually right — your endpoint proposes and the provider completes, which is also how the chart behaves. Commit in the same request when nobody needs to check the entry, such as a reading from a device, and not when a clinician should see it before it counts. Bear in mind that [several commands cannot be committed at all](/sdk/effects/#commands) and are finished by sending or signing instead.
**Whose id the command has.** By default Canvas names it and hands the id back. Pass `command_id` and you name it, which earns its keep when the thing you are writing already has an identity on your side: you can ask whether it reached the chart by that id instead of keeping a mapping, and a retry becomes safe, because posting the same id twice is refused rather than writing a second command. It has to be a genuine UUID — [Choosing the command's id](/sdk/handlers-simple-api-commands/#choosing-the-commands-id) covers how to produce one, including when your own identifier is not a UUID.
**What you want to remember about the entry.** `metadata` attaches a flat map that Canvas stores and never interprets. Use it for what the entry meant on your side — the submission it came from, the version of your mapping — so that months later a chart entry can be traced back to its origin.
**How much a caller learns from a rejection.** Every refusal has the same shape, and every field at fault is reported at once rather than one per round trip. Build against that and a form can mark all its bad fields from a single response, rather than walking its user through them one at a time.
##  Checking that the caller may write to this note 
This is the part worth thinking about, because three questions look alike and are not:
  - **Authentication** — _who is calling?_ `CommandAPI` does not pick this for you, but the schemes are provided: `StaffSessionAuthMixin`, `PatientSessionAuthMixin`, `APIKeyAuthMixin` and `BasicAuthMixin`, each declared by listing it before `CommandAPI` in the bases. Declare none and the endpoint refuses every request rather than admitting anyone. `StaffSessionAuthMixin` answers "a logged-in staff member", and nothing more — see [authentication mixins](/sdk/handlers-simple-api-http/#authentication-mixins) for what each needs.
  - **Authorization** — _may this caller do this to this note?_ The mixin cannot answer that, because it never sees the note.
  - **Attribution** — _who will the chart say wrote it?_ This follows from how the caller authenticated, which makes the scheme you pick a clinical decision and not only a security one. A session-backed request is attributed to the logged-in user, and so is one carrying an access token from the [Authorization Code flow](/api/customer-authentication#authorization-code). A shared secret identifies nobody, so `APIKeyAuthMixin` and `BasicAuthMixin` requests are recorded as **Canvas Bot** — fine for a device feed, wrong for anything a clinician should be seen to have written. See [Acting as a Canvas user](/sdk/handlers-simple-api-http/#acting-as-a-canvas-user).
An endpoint gated only on "is staff" lets any staff member write any command to any note. That may be exactly right — it is roughly what the chart itself allows — but decide it rather than inherit it.
###  Reading who the caller is 
Canvas does the identifying; turning it into something you can check is yours.
When a request arrives with a real session behind it, Canvas sets two headers on it — `canvas-logged-in-user-type` and `canvas-logged-in-user-id`. Neither can be forged: plugin-io strips both if they arrive from the client and sets them only from a session it has verified itself.
Nothing in the SDK turns them into a record, so write the one line that does. There is no built-in `caller()` — this is a helper on your own handler:
    ```python
    from canvas_sdk.v1.data.staff import Staff
    def caller(self) -> Staff | None:
        """The staff member behind this request, or None when there is no staff session."""
        if self.request.headers.get("canvas-logged-in-user-type") != "Staff":
            return None
        return Staff.objects.filter(id=self.request.headers.get("canvas-logged-in-user-id")).first()
    ```
The header carries the staff **key** , which is what `Staff.id` holds — a 32-character UUID with no dashes — so it matches on `id` rather than `dbid`.
Whether those headers are there at all depends on the scheme you chose, and so does who the chart credits for the write:
Scheme| Identifies a person| The command is attributed to  
---|---|---  
`StaffSessionAuthMixin`| yes — a staff member| that staff member  
`PatientSessionAuthMixin`| yes — a patient| that patient  
An [Authorization Code](/api/customer-authentication#authorization-code) access token| yes| the staff member who authorized it  
`APIKeyAuthMixin`| no — a shared key| Canvas Bot  
`BasicAuthMixin`| no — a shared secret| Canvas Bot  
The bottom two authenticate a _system_ , not a person, so there is no logged-in user to read and nothing for the chart to credit. If your endpoint needs a named clinician on the entry, that rules them out.
###  Only the note's author, and only while the note is open 
Canvas already refuses a command bound for a note that has been deleted or cancelled, or that is signed and no longer writable — `canvas_core` validates the note as the effect is applied, inside the transaction, so nothing lands.
What it cannot do is tell your caller.
> **Danger:** Nothing in canvas-plugins reads the note's state, and command effects are applied after your response has already gone back. A closed note therefore answers `201` with a `command_uuid` and then writes no command. Checking before you write is the only way the caller ever finds out.
The check is also where you add the rule Canvas has no opinion on: any staff member may write to any note. If your surface is meant for the note's own provider, that is yours to enforce.
So make both decisions before you write, and return the refusal yourself:
    ```python
    from http import HTTPStatus
    from canvas_sdk.commands import PlanCommand
    from canvas_sdk.commands.api import CommandAPI
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, api
    from canvas_sdk.v1.data.note import Note, NoteStateChangeEvent, NoteStates
    # The states in which a note still accepts documentation.
    OPEN_STATES = (
        NoteStates.NEW,
        NoteStates.PUSHED,
        NoteStates.UNLOCKED,
        NoteStates.RESTORED,
        NoteStates.UNDELETED,
        NoteStates.CONVERTED,
    )
    class PlanAPI(StaffSessionAuthMixin, CommandAPI):
        PREFIX = "/v1"
        @api.post("/plan")
        def insert(self) -> list[Response | Effect]:
            # A body that will not parse is not authorized against — `originate` refuses it with a
            # 400 of its own, and nothing is written in the meantime.
            try:
                body = self.request.json()
            except ValueError:
                return self.originate(PlanCommand)
            note_id = body.get("note_id", "") if isinstance(body, dict) else ""
            if denial := self.refuse(str(note_id)):
                return [denial]
            return self.originate(PlanCommand)
        def refuse(self, note_id: str) -> JSONResponse | None:
            """A response to send instead of writing, or None when the caller may proceed."""
            # One query for the two scalars the decision needs.
            note = Note.objects.filter(id=note_id).values("dbid", "provider__id").first()
            if note is None:
                return JSONResponse({"error": "unknown note"}, status_code=HTTPStatus.NOT_FOUND)
            staff_id = self.request.headers.get("canvas-logged-in-user-id") or ""
            if not staff_id or str(note["provider__id"]) != staff_id:
                return JSONResponse(
                    {"error": "only the note's author can write to it"},
                    status_code=HTTPStatus.FORBIDDEN,
                )
            state = (
                NoteStateChangeEvent.objects.filter(note_id=note["dbid"])
                .order_by("created")
                .values_list("state", flat=True)
                .last()
            )
            if state not in OPEN_STATES:
                return JSONResponse(
                    {"error": "this note no longer accepts documentation"},
                    status_code=HTTPStatus.CONFLICT,
                )
            return None
    ```
Two things worth copying from that shape. It reads the note **once** , with `.values()`, because the check runs on every write. And it answers different refusals differently — `404` for a note that is not there, `403` for the wrong caller, `409` for a closed note — so the caller can tell "you may not" from "not any more".
`OPEN_STATES` is deliberately stricter than Canvas's own rule, which refuses only deleted, cancelled and signed notes. Listing the states you accept, rather than the ones you reject, means a state added to Canvas later is refused until you have decided what it should mean for your endpoint.
> **Warning:** Authorize against the same `note_id` that `originate` will write to — the one in the request body. Take it from anywhere else, such as a path parameter or query string, and a caller can present a note they own to your check while the body names a note they do not: `POST /v1/plan?note_id=<mine>` with `{"note_id": "<someone else's>"}` would pass and then write to the wrong chart.
###  Narrowing who reaches the endpoint at all 
When the rule is about the person rather than the note, put it in `authenticate` — the request never reaches your handler:
    ```python
    from canvas_sdk.handlers.simple_api import SessionCredentials
    from canvas_sdk.v1.data.staff import Staff
    def authenticate(self, credentials: SessionCredentials) -> bool:
        """Only active staff who are providers may write commands here."""
        if credentials.logged_in_user["type"] != "Staff":
            return False
        return Staff.objects.filter(
            id=credentials.logged_in_user["id"], active=True, primary_practice_location__isnull=False
        ).exists()
    ```
Which of the two you use is a real choice. `authenticate` is cheaper and applies to every route, but it cannot see the note. A per-request check can, and it can explain itself in the response. Rules about the _caller_ belong in the first; rules about the _note_ belong in the second.
##  Serving every command from one endpoint 
Nothing ties an endpoint to a single command — the command is an argument. Put the command in the path and look it up, and one endpoint serves the lot.
Two things are worth getting right before you write it.
**Key the lookup on each command's own`Meta.key`.** That is the value `CommandAPI` uses when it looks a command up by id, so deriving the path segment from it keeps the URL and the lookup naming the same schema. It also saves you transcribing keys that are not guessable from the class name — `hpi`, `reasonForVisit`, `structuredAssessment`, `chartSectionReview`, `exam`, `ros`.
**Allow actions per command, not from one shared set.** [Not every command accepts every action](/sdk/effects/#commands): Prescribe and Refill are finished by sending rather than committing, Lab Order takes `send`, Imaging Order and Refer take `delegate` and `sign`, and Reason for Visit takes none of them. This matters more than it looks — see the warning below.
    ```python
    from http import HTTPStatus
    from canvas_sdk.commands import (
        AllergyCommand,
        AssessCommand,
        DiagnoseCommand,
        HistoryOfPresentIllnessCommand,
        LabOrderCommand,
        PlanCommand,
        PrescribeCommand,
    )
    from canvas_sdk.commands.api import CommandAPI
    from canvas_sdk.commands.base import _BaseCommand
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.simple_api import JSONResponse, Response
    from canvas_sdk.handlers.simple_api import StaffSessionAuthMixin, api
    # Keyed on Meta.key, so the path segment always matches the schema CommandAPI looks up.
    COMMANDS: dict[str, type[_BaseCommand]] = {
        command.Meta.key: command
        for command in (
            AllergyCommand,
            AssessCommand,
            DiagnoseCommand,
            HistoryOfPresentIllnessCommand,
            LabOrderCommand,
            PlanCommand,
            PrescribeCommand,
        )
    }
    # What each command is actually finished with. Nothing infers this for you.
    STAGED_ACTIONS = {"commit", "delete", "enter_in_error"}
    ACTIONS: dict[str, set[str]] = {
        AllergyCommand.Meta.key: STAGED_ACTIONS,
        AssessCommand.Meta.key: STAGED_ACTIONS,
        DiagnoseCommand.Meta.key: STAGED_ACTIONS,
        HistoryOfPresentIllnessCommand.Meta.key: STAGED_ACTIONS,
        PlanCommand.Meta.key: STAGED_ACTIONS,
        LabOrderCommand.Meta.key: {"delete", "send", "enter_in_error"},
        PrescribeCommand.Meta.key: {"delete", "review", "send", "enter_in_error"},
    }
    def unknown_command() -> Response:
        """The one response every route shares, so a bad path reads the same way throughout."""
        return JSONResponse(
            {"error": "no such command", "commands": sorted(COMMANDS)},
            status_code=HTTPStatus.NOT_FOUND,
        )
    class ChartingAPI(StaffSessionAuthMixin, CommandAPI):
        PREFIX = "/commands"
        @api.post("/<schema>")
        def create(self) -> list[Response | Effect]:
            command = COMMANDS.get(self.request.path_params["schema"])
            if command is None:
                return [unknown_command()]
            return self.originate(command)
        @api.put("/<schema>/<command_id>")
        def update(self) -> list[Response | Effect]:
            command = COMMANDS.get(self.request.path_params["schema"])
            if command is None:
                return [unknown_command()]
            return self.edit(command, self.request.path_params["command_id"])
        @api.post("/<schema>/<command_id>/<action>")
        def act(self) -> list[Response | Effect]:
            schema = self.request.path_params["schema"]
            command = COMMANDS.get(schema)
            if command is None:
                return [unknown_command()]
            action = self.request.path_params["action"]
            allowed = ACTIONS.get(schema, set())
            if action not in allowed:
                return [
                    JSONResponse(
                        {"error": f"{schema} does not accept that action", "allowed": sorted(allowed)},
                        status_code=HTTPStatus.BAD_REQUEST,
                    )
                ]
            return self.action(command, self.request.path_params["command_id"], action)
    ```
That is the whole surface: `POST /commands/hpi` creates, `PUT /commands/hpi/<id>` revises, `POST /commands/hpi/<id>/commit` finishes. Adding a command is two lines — one in `COMMANDS`, one in `ACTIONS`.
> **Warning:** Gating the actions is not defensive tidiness, it is the difference between a write landing and silently not landing. Every command class inherits `commit()`, so `POST /commands/prescribe/<id>/commit` would build a valid effect and answer `200` — and Canvas would then refuse to apply it, because Prescribe has no COMMIT. The caller is told the write succeeded when it did not. An action absent from `ACTIONS` is refused before any effect is built.
Two smaller things the shape buys you:
  - **One`404` for an unknown command, everywhere.** `unknown_command()` is a plain function rather than a method, because `CommandAPI` reserves `originate`, `edit` and `action`, and SimpleAPI raises at class-definition time if a subclass shadows a base method.
  - **The`<schema>` segment is also your allow-list.** A command absent from `COMMANDS` is unreachable, so adding `CommandAPI` to a plugin does not expose every command in the SDK — only the ones you named.

Source: https://docs.canvasmedical.com/guides/your-first-application/

This guide will walk you through the process of installing, initializing, and customizing embeddable applications in Canvas.
##  What Are Applications in Canvas? 
Applications in Canvas are embeddable plugins that enhance the functionality of the Canvas platform. They allow developers to create custom features accessible directly from within the Canvas interface, such as interactive tools, data visualizations, or workflow integrations. These applications can be configured to appear globally or within specific contexts, such as the patient chart page.
##  Step 1: Install and Configure the Canvas CLI 
Follow the instructions in the [Canvas documentation](https://docs.canvasmedical.com/guides/your-first-plugin/#1-install-the-canvas-cli) to install and configure the Canvas CLI. Once complete, ensure that you can successfully run `canvas` commands from your terminal.
##  Step 2: Initialize an Application 
To create a new application, run the following command:
    ```bash
    canvas init application
    ```
This will generate a boilerplate application along with a `CANVAS_MANIFEST.json` file.
##  Step 3: Understanding the `CANVAS_MANIFEST.json` File 
The `CANVAS_MANIFEST.json` file describes your application and its components. Below is an example of a manifest and a description of the customizable properties:
    ```json
    {
        "sdk_version": "0.1.4",
        "plugin_version": "0.0.1",
        "name": "my_cool_application",
        "description": "Edit the description in CANVAS_MANIFEST.json",
        "url_permissions": [
            {
                "url": "https://my-application.com",
                "permissions": []
            }
        ],
        "components": {
            "applications": [
                {
                    "class": "my_cool_application.applications.my_application:MyApplication",
                    "name": "My Application",
                    "description": "An Application that does xyz...",
                    "scope": "global",
                    "icon": "assets/python-logo.png",
                    "menu_position": "top",
                    "menu_order": "100",
                    "show_in_panel": false,
                    "panel_priority": 100
                }
            ],
            "commands": [],
            "content": [],
            "effects": [],
            "views": []
        },
        "variables": [],
        "tags": {},
        "references": [],
        "license": "",
        "diagram": false,
        "readme": "./README.md"
    }
    ```
###  Customizable Properties 
  1. **name** : The display name of the application.
  2. **description** : A brief description of the application.
  3. **icon** : The icon for the application. This can be a URL to an image or a path inside the plugin package.
  4. **scope** :
     - `global`: The app will appear across all contexts.
     - `patient_specific`: The app will appear only in the patient chart page.
     - `provider_menu_item`: The app button will be displayed on the provider's menu.
     - `portal_menu_item`: The app button will be displayed on the patient portal menu.
  5. **url_permissions** : The allowed urls and permissions for the application. This is used for security purposes. For more info check the [Application Handler](/sdk/
handlers-applications).
  6. **menu_position** : Determines where the menu item will be placed within the menu (this configuration applies only to the providers menu)
     - `top`: The item will be placed on the top section.
     - `bottom`: The item will be placed in the bottom section - this section should display items that open in a new window.
  7. **menu_order** : How the items will be ordered in the menu. e.g 100, 200
  8. **show_in_panel** : If you want to increase your application's visibility and display it alongside other panel buttons (instead of in the applications drawer), you can set this attribute
  9. **panel_priority** : How the applications will be ordered in the panel section. e.g 100, 200
##  Step 4: Overriding the Application Behavior 
Developers must extend the `Application` class and override the `on_open` method to define the behavior when the app icon is clicked. Below is an example implementation:
    ```python
    from canvas_sdk.effects import Effect
    from canvas_sdk.effects.launch_modal import LaunchModalEffect
    from canvas_sdk.handlers.application import Application
    class MyApplication(Application):
        """An embeddable application that can be registered to Canvas."""
        def on_open(self) -> Effect:
            """Handle the on_open event."""
            # Implement this method to handle the application on_open event.
            return LaunchModalEffect(
                url="http://localhost:8000",
                target=LaunchModalEffect.TargetType.DEFAULT_MODAL
            ).apply()
    ```
###  Key Details 
  - **`on_open` Method**:
    - Called when the user clicks on the app icon.
    - Should return a `LaunchModalEffect` that specifies:
      - **url** : The URL to open.
      - **target** : The display target.
###  Target Options 
  - `DEFAULT_MODAL`: Opens the URL in a modal centered on the screen.
  - `NEW_WINDOW`: Opens the URL in a new browser window.
  - `PAGE`: Opens the URL as a page in the app
  - `RIGHT_CHART_PANE`: Opens the URL in the right-hand pane of the patient chart.
  - `RIGHT_CHART_PANE_LARGE`: Opens the URL in an enlarged right-hand pane of the patient chart.
##  Step 5: Installing the Application 
To install your application, run:
    ```bash
    canvas install <path/to/application>
    ```

# Your First Plugin (with Claude Code)

Source: https://docs.canvasmedical.com/guides/your-first-plugin-with-claude-code/

Canvas plugins let you customize the EHR — reacting to events, reading patient data, and returning effects that alter workflows. This guide uses an AI-assisted approach powered by Claude Code and the Canvas Plugin Assistant (CPA), getting you from idea to deployed plugin in minutes.
> **Info:** Haven't yet advanced to AI-assisted coding? See [Your First Plugin (Manual)](/guides/your-first-plugin/) to build your plugin by hand.
##  Background: AI-Assisted Plugin Development 
[Claude Code](https://docs.anthropic.com/en/docs/claude-code/overview) is Anthropic's agentic coding tool — it can read, write, and execute code autonomously in your terminal. Rather than copying and pasting snippets from documentation or typing code by hand, you can describe what you want in plain English and Claude Code does the programming with your supervision.
Claude Code supports a plugin marketplace. We built the Canvas Plugin Assistant (CPA) Claude Code plugin (yes, a plugin to make plugins!) with deep knowledge of the Canvas SDK, common plugin patterns, and best-practice workflows in plugin development.
CPA accelerates the entire plugin development lifecycle — from brainstorming requirements and scaffolding code, to running tests and deploying to your instance and rapidly cycling through user acceptance testing and enhancements.
Together, Claude Code with CPA lets developers go from an idea to a working, deployed plugin through natural conversation at warp speed.
##  Prerequisites 
  - Python 3.12+ installed
  - A Canvas instance with admin access
  - [OAuth credentials configured](/api/customer-authentication/) and saved locally in `~/.canvas/credentials.ini` (register an application with `confidential` client type and `client-credentials` grant type). For more, see [these configuration steps](/guides/your-first-plugin/#2-configure-the-canvas-cli-for-your-instances)
  - [Claude Code installed](https://docs.anthropic.com/en/docs/claude-code/overview)
##  1\. Install the Canvas Plugin Assistant and Set Up Your Environment 
Follow the installation and setup instructions in the [Canvas Plugin Assistant README](https://github.com/canvas-medical/coding-agents/tree/main/canvas-plugin-assistant). Once complete, run `/cpa:check-setup` to verify everything is ready.
##  2\. Describe Your First Plugin 
Run `/cpa:new-plugin` to start building. CPA will ask clarifying questions via an interactive chip interface. Describe what you want in plain English. You can find examples of what's possible [here](https://github.com/Medical-Software-Foundation/canvas/tree/main/extensions), [here](https://github.com/canvas-medical/canvas-plugins/tree/main/example-plugins), and [here](https://www.canvasmedical.com/plugins). For example:
> I want a plugin that adds a button to the note header. When clicked, the button should inject a Reason for Visit command into the note with the text "hello world".
Here's what happens next:
  1. **Brainstorm** — CPA asks follow-up questions to refine your requirements
  2. **Specification** — CPA generates a `plugin-spec.md` for your review. Read through it and approve or request changes
  3. **Scaffold** — CPA creates the [plugin project structure](/guides/your-first-plugin/#4-navigate-the-structure-of-a-plugin), manifest, and handler files
  4. **Implement** — CPA writes the protocol/handler code based on the spec
  5. **Test** — CPA generates and runs tests to verify the plugin works correctly
At any point, if you have more detail and direction to give, in any format (other markdown files, PDF files, images), you can simply instruct Claude to read those files and use them in formulating the plan.
##  3\. Deploy and Test 
When you're at the point of completion where you need to try the plugin yourself, run:
    ```text
    /cpa:deploy
    ```
CPA validates the plugin, bumps the version, deploys it to your Canvas instance, and starts log monitoring so you can see output in real time.
To test our example first plugin, open a patient chart in your Canvas instance, create a new note, and click the button in the note header. You should see a Reason for Visit command appear with the text "hello world".
##  4\. Next Steps: Keep Iterating in Conversation with Claude 
The real power of AI-assisted development is iterating. Now that your plugin is deployed, enhance it with follow-up prompts:
###  Make it dynamic and patient-specific 
Ask CPA to update the plugin so the RFV text follows the classic clinical one-liner format, pulling patient data dynamically from the Canvas data module:
> Update the plugin so instead of "hello world", the RFV text is a clinical one-liner: "{patient first and last name} is a {age} year old {sex} presenting with ___". Pull the patient data dynamically.
###  Handle existing RFV 
Ask CPA to handle the case where the note already has a Reason for Visit command — editing the existing one instead of creating a duplicate:
> Update the plugin to check if the note already has a Reason for Visit command. If it does, edit the existing one instead of creating a new one.
###  Ask Claude to check logs and troubleshoot 
The `/cpa:deploy` command will start a subagent called `deploy-uat`, which runs a background task to access the `canvas logs` stream. Ask Claude to look at them anytime you need help troubleshooting. You can also of course view logs in the shell manually with:
    ```bash
    uv run canvas logs <your-instance>
    ```
###  Keep going 
Continue exploring the [SDK documentation](/sdk/) and browse other [guides](/guides/) to see what's possible with Canvas plugins. When you're ready to harden your plugin for production, run `/cpa:coverage` to check test coverage and improve tests, `/cpa:security-review` to audit for common security issues, and `/cpa:database-performance-review` to ensure efficient data retrieval. When you feel everything is ready to finalize, use the `/cpa:wrap-up` command.

# Your First Plugin (Manual)

Source: https://docs.canvasmedical.com/guides/your-first-plugin/

Plugins are your tool for customizing the Canvas experience. By using the modules of the Canvas SDK, you can react to [events](/sdk/events/) emitted from the EHR, request additional [data](/sdk/data/) if needed, and respond with [effects](/sdk/effects/) that alter workflows and add or change data in Canvas. You can also use [utils](/sdk/utils/) to do things like call out to web services with our provided HTTP client.
> **Warning:** This guide is for manual coding. Want a faster, AI-assisted approach? Check out [Your First Plugin (with Claude Code)](/guides/your-first-plugin-with-claude-code/), which uses an AI assistant to guide you through building and deploying your plugin.
##  Video 
The video below showcases a Canvas engineer working through this guide step-by-step.
##  1\. Install the Canvas CLI 
To install the Canvas CLI, simply `pip install canvas`. Python 3.11–3.14 (`>=3.11, <3.15`) is required. You can find additional detail on the features of the Canvas CLI [here](/sdk/canvas_cli/).
##  2\. Configure the Canvas CLI for your instances 
The Canvas CLI uses OAuth credentials to connect to your Canvas instance. If you've used our FHIR API, you'll be very familiar with the process for [registering credentials](/api/customer-authentication/). Register a separate OAuth application, choosing `confidential` for the Client type, and `client-credentials` for the Authorization grant type. Redirect URIs can be left blank, and the Algorithm should be `No OIDC support`. Note the client_id and client_secret for the next step.
Create a file at the path `~/.canvas/credentials.ini`. Here is what its contents should look like:
    ```ini
    [buttered-popcorn]
    client_id=butter
    client_secret=salt
    [buttered-popcorn-dev]
    client_id=devbutter
    client_secret=devsalt
    is_default=true
    ```
Each section represents credentials for a different Canvas instance. Replace the section headers with your Canvas subdomains. The example configuration provided would be valid for instances with URLs `https://buttered-popcorn.canvasmedical.com` and `https://buttered-popcorn-dev.canvasmedical.com`.
You can optionally set the `is_default` flag for the instance you wish to be implied when using the CLI. If no section is set as default, the first one will be considered default.
##  3\. Initialize a new plugin 
The Canvas CLI gives you a great head start when creating a plugin. Simply run `canvas init`, and answer the prompt to name your plugin.
    ```sh
    $ canvas init
      [1/1] project_name (My Cool Plugin): Paperwork Eviscerator
    Project created in /Users/andrew/src/canvas-plugins/paperwork-eviscerator
    ```
This output shows the location of our freshly generated plugin project.
##  4\. Navigate the structure of a plugin 
Let's take a look at what was generated for us.
    ```sh
    $ tree paperwork-eviscerator/
    paperwork-eviscerator/
    ├── paperwork_eviscerator
    │    ├── CANVAS_MANIFEST.json
    │    ├── README.md
    │    └── handlers
    │         ├── __init__.py
    │         └── event_handlers.py
    ├── pyproject.toml
    └── tests
        ├── __init__.py
        └── test_models.py
    5 directories, 9 files
    ```
###  CANVAS_MANIFEST.json 
The CANVAS_MANIFEST.json is particularly important. It is used during the installation of the plugin.
    ```json
    {
        "sdk_version": "0.1.4",
        "plugin_version": "0.0.1",
        "name": "paperwork_eviscerator",
        "description": "Edit the description in CANVAS_MANIFEST.json",
        "components": {
            "handlers": [
                {
                    "class": "paperwork_eviscerator.handlers.event_handlers:Handler",
                    "description": "A handler that does xyz...",
                    "data_access": {
                        "event": "",
                        "read": [],
                        "write": []
                    }
                }
            ],
            "commands": [],
            "content": [],
            "effects": [],
            "views": []
        },
        "variables": [
            {"name": "my_secret_code", "sensitive": true}
        ],
        "tags": {},
        "references": [],
        "license": "",
        "diagram": false,
        "readme": "./README.md"
    }
    ```
The name, plugin version, and description are all surfaced in your Canvas instance when viewing installed plugins.
Only handlers declared here are invoked by the plugin runner. If they are not declared, they will be ignored.
Secrets can be declared (though not defined) here. Any secrets declared here will be initialized on plugin install, and can be set in the plugin listing in the Settings section of your Canvas instance.
###  README.md 
Share details about the purpose of your plugins and how it works in this README file.
###  handlers/event_handlers.py 
This file contains the handler class declared in the manifest file. We've included some sample content and copious comments for inspiration.
    ```python
    from canvas_sdk.events import EventType
    from canvas_sdk.handlers import BaseHandler
    from logger import log
    # Inherit from BaseHandler to properly get registered for events
    class Handler(BaseHandler):
        """
        You should put a helpful description of this handler's behavior here.
        """
        # Name the event type you wish to run in response to
        RESPONDS_TO = EventType.Name(EventType.ASSESS_COMMAND__CONDITION_SELECTED)
        NARRATIVE_STRING = "I was inserted from my plugin's handler."
        def compute(self):
            """
            This method gets called when an event of the type RESPONDS_TO is fired.
            """
            # This class is initialized with several pieces of information you can
            # access.
            #
            # `self.event` is the event object that caused this method to be
            # called.
            #
            # `self.target` is an identifier for the object that is the subject of
            # the event. In this case, it would be the identifier of the assess
            # command. If this was a patient create event, it would be the
            # identifier of the patient. If this was a task update event, it would
            # be the identifier of the task. Etc, etc.
            #
            # `self.context` is a python dictionary of additional data that was
            # given with the event. The information given here depends on the
            # event type.
            #
            # `self.secrets` is a python dictionary of the secrets you defined in
            # your CANVAS_MANIFEST.json and set values for in the uploaded
            # plugin's configuration page: <emr_base_url>/admin/plugin_io/plugin/<plugin_id>/change/
            # Example: self.secrets['WEBHOOK_URL']
            # You can log things and see them using the Canvas CLI's log streaming
            # function.
            log.info(self.NARRATIVE_STRING)
            # Craft a payload to be returned with the effect(s).
            payload = {
                "note": {"uuid": self.context["note"]["uuid"]},
                "data": {"narrative": self.NARRATIVE_STRING},
            }
            # Return zero, one, or many effects.
            # Example:
            # return [Effect(type=EffectType.LOG, payload=json.dumps(payload))]
            return []
    ```
##  5\. Listen for an Event 
Set the `RESPONDS_TO` value to the [Event Type](/sdk/events/#event-types-and-context) you're interested in.
##  6\. Return an Effect 
Form an [Effect](/sdk/effects/#effect-types) to return to your Canvas instance.
##  7\. Deploy and use your plugin 
When your plugin is just the way you'd like it, deploying is simple. Navigate to the root of your plugin project (i.e. `paperwork-eviscerator/`) and run `canvas install <path/to/plugin_package>` (i.e. `canvas install paperwork_eviscerator`) and your plugin will be packaged, uploaded, installed, and enabled. As you make changes to your plugin, run the same command to update the code of the installed plugin.
##  8\. Tail the logs 
To view logs and to surface any errors with your plugin, run `canvas logs --host buttered-popcorn-dev` (replace with your Canvas instance name). This will tail the logs for all plugins installed on that instance.

# EHI Export

Source: https://docs.canvasmedical.com/documentation/ehi-export/

Canvas supports the **export of electronic health information (EHI)** based on FHIR Bulk Data Access.
##  Creating a Single Patient Export 
###  In the UI 
To generate a single patient export, navigate to `Fhir bulk data exports` in your admin settings.
Click on `ADD FHIR BULK DATA EXPORT` to pull up the tool. Select the appropriate Oauth application from the dropdown. These are typically created by your team as a part of implementation. Support can also help to create one if needed. Export type defaults to 'Patient'. Search for the patient and click `Start Export`.
The export will generate links to the output files for each resource. Clicking each will download the files locally.
> **Warning:** This functionality is permission based. If you do not have access and need it, please reach out to your internal administrators. They can work with our support team to ensure the permissions are assigned to the necessary groups.
###  Using the API 
You can initiate a single patient export by issuing a request like the one below:  
`GET https://fumage-<instance-name>.canvasmedical.com/Patient/<id>/$export`
##  Creating a Population Export 
Canvas also supports exporting EHI for a group of patients or all patients. To request an export, please contact [support](https://portal.usepylon.com/canvas-medical/forms/standard) and provide the following information:
  - Your instance name (the url of your instance)
  - Your username
  - Your role
  - The group of patients, or specify all patients
  - The purpose of the export.
> **Info:** Please note that population exports may take a significant time to process depending on the amount of data in your instance.
The Canvas team can initiate the bulk export on your behalf. The output will be availble within the `ADD FHIR BULK DATA EXPORT` table.
##  Format 
EHI is exported as standard FHIR R4 resources in Newline Delimited JSON format, as outlined by the [FHIR Bulk Data Access pattern](https://hl7.org/fhir/uv/bulkdata/STU1.0.1/).   
###  Resources 
The resources in scope for the response are:
  - The patient resource itself.
  - Any resource that is associated with the patient.
The table below lists the Canvas resources included in the patient recordset:
