Remove a calendar event after a cancellation request
Send a cancellation request through Ably and have Notis remove the specified event from Google Calendar.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Delete event
Deletes a specified event by `event id` from a google calendar (`calendar id`); this action is idempotent and raises a 404 error if the event is not found.
Why this helps
Cancellations can be forgotten when they arrive in a message and still require a separate calendar cleanup.
- Keep event cleanup connected to the cancellation request
- Delete a specified event by its identifier
- See the workflow result in a run report
Setup
Build it in a few focused steps.
- 1Connect Ably and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and provide a name and prompt.
- 3In one instruction, ask Notis to delete only the clearly identified event when the request is an explicit cancellation.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real cancellation request for a safe, specified event.
Questions about this workflow
What happens if the event is already missing?
Delete event is idempotent, but raises a 404 error if the event is not found.
