Notify course participants when an event is canceled
When a course event disappears from the calendar, give the right people a clear update in Canvas with a concise explanation and next step.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
Create conversation
Use to send messages in canvas by creating a new conversation or adding to an existing one; an existing conversation with the same recipients (and matching scope/filter, if specified) may be reused unless `force new` is true.
Why this helps
A calendar cancellation can leave course participants unsure whether plans changed or where to look for an update.
- Share cancellations in a course communication channel.
- Include the event summary when it is available.
- Reduce repeated questions about changed plans.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Canvas once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3Tell Notis which canceled events affect a course, who should receive a Canvas conversation, and how to explain the next step.
- 4Pick the Event Canceled or Deleted trigger, choose where run reports should go, and test with one real example.
