Know what a calendar change means for Cal bookings
When meeting details shift, get a focused review of potentially related Cal bookings and the fields that changed.
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
Fetch all bookings
Fetches a list of bookings, optionally filtered by status, attendee, date range, or by event/team ids (which must belong to/include the authenticated user respectively), with support for pagination and sorting.
Why this helps
A changed event can leave you wondering whether a corresponding Cal booking also needs attention.
- See changed fields beside potentially related bookings
- Reduce manual cross-checking after edits
- Get a clear follow-up prompt

- 1Connect Google Calendar and Cal once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Tell Notis to review the changed event details against Cal bookings and report likely matches and any differences for follow-up.
- 4Pick Event Updated as the trigger and choose where run reports should go.
- 5Test with one real event update.
Questions about this workflow
Will this automatically edit the Cal booking?
No. The available Cal action here fetches bookings, so this workflow reports possible follow-up for you.
Can it always identify the matching booking?
Not necessarily. It can compare returned details, but ambiguous matches should be reviewed.
