Overview
This node interacts with the Canvas LMS API to retrieve information about submissions for assignments within courses. Specifically, the "Get" operation under the "Submission" resource fetches submission data for a given assignment in a course. This is useful for educators or administrators who want to programmatically access student submissions for grading, review, or record-keeping.
Practical examples:
- Automatically retrieving a student's submission for an assignment to integrate with other grading systems.
- Fetching all submissions for an assignment to generate reports or analytics.
- Monitoring submissions to trigger notifications or workflows when new submissions are made.
Properties
| Name | Meaning |
|---|---|
| Course ID | The unique identifier of the course containing the assignment. |
| Assignment ID | The unique identifier of the assignment whose submissions are being retrieved. |
| User ID | The unique identifier of the user (student) whose submission is to be fetched. |
Output
The output JSON contains a data field which holds the submission details returned by the Canvas API. For the "Get" operation on submissions, this typically includes information such as submission status, submitted files or text, timestamps, grades (if any), and comments related to the submission.
Example structure of the output JSON:
{
"data": {
// Submission details object as returned by Canvas API
}
}
No binary data output is indicated for this operation.
Dependencies
- Requires an API key credential for authenticating with the Canvas LMS API.
- The node uses the Canvas API base URL and an access token provided via credentials.
- No additional external dependencies beyond the Canvas API and n8n's HTTP request helpers.
Troubleshooting
Common issues:
- Invalid or expired API token: Ensure the API key credential is valid and has sufficient permissions.
- Incorrect Course ID, Assignment ID, or User ID: Verify that these IDs exist and are correct in Canvas.
- Network or connectivity issues: Check network access to the Canvas API endpoint.
Error messages:
- Errors from the Canvas API will be wrapped and reported with context indicating the resource and operation.
- If the node fails due to missing parameters, ensure all required fields (Course ID, Assignment ID, User ID) are provided.
- Pagination errors are unlikely here since the "Get" operation fetches a specific submission, but if used differently, ensure proper handling of paginated responses.
