Fetch submission files when your workflow calls
Start review work as soon as another system signals that files are ready.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get submission files
Retrieves files from a student's canvas assignment submission, processing text, binary, and zip files, and providing s3 download urls if s3 integration is active and uploads are successful.
Why this helps
File retrieval is a manual handoff that slows grading and feedback workflows.
- Shorten review handoffs
- Process files consistently
- Reduce download chasing
Setup
Build it in a few focused steps.
- 1Connect Canvas in Notis once.
- 2Create an automation for submission file retrieval.
- 3Describe which course, assignment, and user identifiers the webhook supplies.
- 4Choose a webhook trigger and report destination.
- 5Send one test webhook and verify the returned file details.
Questions about this workflow
Can it process zip files?
