Close the loop when a calendar event is canceled
A cancellation should not leave someone waiting for an update. Let your voice agent handle the call you define.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
Make a phone call from agent
Initiate calls
Why this helps
Canceled meetings still need a human-sounding follow-up, and that task is easy to lose among everything else.
- Create a direct follow-up when an event is canceled or deleted.
- Keep cancellation messaging consistent.
- Avoid leaving contacts without a next step.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Bolna once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3Describe in one instruction who to call after a cancellation and what message or next step to share.
- 4Choose Event Canceled or Deleted as the trigger and select a report channel.
- 5Test with one real canceled event and check the run report.
