Clear cancelled bookings from your calendar
When a booking is cancelled, send the cancellation details and remove its 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
A cancelled booking left on your calendar can lead to confusion and wasted preparation.
- Remove events tied to cancelled bookings.
- Keep your calendar more accurate.
- Reduce manual cleanup after a cancellation.
Setup
Build it in a few focused steps.
- 1Connect Backendless and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Describe that a cancellation should delete its corresponding event using the identifiers available in the request.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real cancellation and verify the intended event was removed.
Questions about this workflow
What should the cancellation request include?
Include reliable details to identify the calendar and event to delete. Google Calendar needs a calendar ID and event ID.
What happens if the event is already gone?
The delete action is idempotent, but it reports a 404 if the event cannot be found.
