Overview
This node integrates with the Canvas LMS API to retrieve information about discussion topics within a specific course. The "Get" operation for the "Discussion" resource fetches details of a single discussion topic by its ID and the associated course ID.
This node is useful in scenarios where you want to automate workflows involving course discussions, such as monitoring or extracting discussion content for reporting, archiving, or further processing in other systems.
Example use cases:
- Automatically fetching a discussion topic's details when triggered by an event.
- Integrating Canvas discussion data into external dashboards or analytics tools.
- Using discussion content to trigger notifications or follow-up actions in other apps.
Properties
| Name | Meaning |
|---|---|
| Course ID | The unique identifier of the course containing the discussion. This is required to specify the course context. |
| Discussion ID | The unique identifier of the discussion topic to retrieve. This identifies which discussion topic's details to fetch. |
Output
The node outputs a JSON object under the json field with a data property containing the discussion topic details as returned by the Canvas API.
The structure typically includes all standard fields of a Canvas discussion topic, such as title, message, creation date, author info, and any other metadata provided by the API.
No binary data output is produced by this operation.
Dependencies
- Requires an API key credential for authenticating with the Canvas LMS API.
- The Canvas LMS instance URL and access token must be configured in the node credentials.
- The node uses HTTP requests to communicate with the Canvas REST API endpoints.
Troubleshooting
Common issues:
- Invalid or missing Course ID or Discussion ID parameters will cause the API call to fail.
- Incorrect or expired API authentication token will result in authorization errors.
- Network connectivity issues can prevent successful API calls.
Error messages:
- Errors from the Canvas API are wrapped and thrown as node operation errors with messages indicating the resource and operation involved.
- For example, if the discussion topic does not exist or access is denied, the error message will reflect that.
Resolutions:
- Verify that the Course ID and Discussion ID are correct and correspond to existing resources.
- Ensure the API key credential is valid and has sufficient permissions.
- Check network connectivity and Canvas API availability.
