Clear cancelled public events from your calendar
Remove a cancelled event after checking the organizer's notice.
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
Cancelled events can remain on a busy calendar and create confusion about what still needs attention.
- Confirm the cancellation against the supplied source page.
- Remove a matching event that no longer needs calendar space.
- Avoid deleting an event when the match is uncertain.
Setup
Build it in a few focused steps.
- 1Connect Browserless and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for cancellation cleanup.
- 3Tell Notis to inspect the supplied notice and delete only the explicitly identified matching event when cancellation is clear.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real cancellation and verify the correct event was removed.
Questions about this workflow
What if more than one event matches?
Instruct Notis to report the ambiguity and make no deletion until the intended event is identified.
Is deleting an event reversible?
The action deletes the specified event. Verify the event identifier and cancellation notice before allowing the automation to proceed.
