Keep calendar events aligned with rescheduling notices
When an organizer changes the details, update the event you already have.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Patch Event
Updates specified fields of an existing event in a google calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar id` and `event id` are valid and the user has write access to the calendar.
Why this helps
A changed event time can leave an outdated calendar entry that causes missed meetings or unnecessary follow-up.
- Update a confirmed existing event instead of creating a duplicate.
- Keep event details aligned with the organizer's latest notice.
- Review the update in a Notis run report.
Setup
Build it in a few focused steps.
- 1Connect Browserless and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for event changes.
- 3Tell Notis to inspect the supplied notice, match only the explicitly identified Calendar event, and patch only confirmed changed details.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real rescheduling notice and verify the existing event was updated.
Questions about this workflow
What does Notis need to identify the existing event?
Provide the matching event identifier or enough unambiguous context to find it. The instruction should require reporting ambiguity rather than editing a possibly wrong event.
Will the patch replace all event fields?
Patch Event uses patch semantics, so only the fields provided are changed. Array fields such as attendees are fully replaced if provided.
