Make important meeting changes harder to miss
When a meeting changes, a voice update can help the people who need to adjust their plans hear about it quickly.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Action
Make a phone call from agent

Why this helps
A changed time or detail can be missed in a stream of calendar alerts, creating avoidable confusion.
- Turn important event edits into a direct voice update.
- Tell Notis which kinds of changes need a call.
- Cut down on manual notification and follow-up.
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.
- 3In one instruction, name the change types that matter, who should be called, and what the agent should communicate.
- 4Choose Event Updated as the trigger and select a report channel.
- 5Test with one real event edit and review the call and report.
