Handle clear cancellation requests from Basin
When a submitted request clearly asks to cancel an identifiable event, Notis can delete that 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
Cancellation requests can remain buried in form responses while the now-unwanted event stays on your calendar.
- Remove a specified event after a clear cancellation request.
- Reduce manual follow-up between a form and calendar.
- Keep cancellation handling tied to the submitted request.
Setup
Build it in a few focused steps.
- 1Connect Basin and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3In one instruction, tell Notis to delete an event only when the response clearly requests cancellation and identifies the specific event.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real cancellation request and a suitable event you can verify.
Questions about this workflow
What if the cancellation request is ambiguous?
Have Notis report it for review rather than delete an event without a clear match.
What happens if the event is already gone?
The action is idempotent and returns a 404 error if the event is not found.
Can this delete a whole calendar?
No. It deletes a specified event by event id from a calendar.
