Correct event details from an updated booking request
When booking details are corrected, update the calendar entry that reflects them.
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 corrected meeting detail can be missed when the original event was created earlier.
- Apply explicitly supplied corrections to a matching event.
- Keep event details aligned with booking information.
- Avoid rewriting the full event for a small correction.
Setup
Build it in a few focused steps.
- 1Connect Calendarhero and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis what you want from any channel.
- 3Ask Notis to find the matching event and patch only the corrected fields supplied in the Calendarhero request.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real correction and review the fields changed.
Questions about this workflow
Does it replace every event field?
No. Patch Event updates only provided fields, though array fields such as attendees are fully replaced if included.
What if the matching event is unclear?
Tell Notis to report multiple or uncertain matches for review instead of patching the wrong event.
