Check E2B notifications when course files arrive
A course file can be a cue to check whether your sandbox lifecycle notifications are configured as expected.
Trigger

Action
List All Webhooks
Tool to retrieve all registered webhooks for your team. Use when you need to view all webhook configurations, audit webhook settings, or manage multiple webhooks.
Why this helps

- Make webhook configuration visible during file review.
- Keep lifecycle notification setup easy to audit.
- Save a manual trip to E2B when a new file arrives.

- 2Create an automation for course file follow-up.
- 3Tell Notis to list registered E2B webhooks when a new course file is uploaded and summarize their configuration.
- 4Pick the New Canvas File Upload trigger and choose where run reports go.
- 5Test with one real upload event and confirm webhook details appear in the report.
Questions about this workflow
Does this workflow send the uploaded file to E2B?
No. It retrieves the E2B webhook list. File transfer is not part of the listed action.
Can I update webhook settings from this workflow?
This workflow only lists webhooks. Updating a webhook requires the separate update action and explicit configuration.
