Remove calendar events for cancelled commitments
Clear obsolete plans as soon as your source material confirms they are cancelled.
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.

Questions about this workflow
What if multiple events match?
