Notis

Update only the event details that changed

Send a change request through Ably and have Notis patch the specified fields on an existing event.

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

Small changes to an event can lead to re-entering details that were already correct.

  • Update specified event fields with patch semantics
  • Avoid rebuilding the entire event for a small change
  • Keep a request based trail through the run report

Setup

Build it in a few focused steps.

  • 1Connect Ably and Google Calendar once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and add its name and prompt.
  • 3In one instruction, ask Notis to patch the specified existing event fields using the incoming change request.
  • 4Pick the webhook trigger and choose where run reports should go.
  • 5Test with one real change to an existing event you can verify.

Questions about this workflow

Does patching replace unspecified fields?

Patch Event uses patch semantics, so fields not provided are not meant to be replaced. If you provide an array field such as attendees, that array is fully replaced.

What must the request identify?

It needs enough information for Notis to identify the calendar and event and to know which fields to update.
