The Calendar API now distinguishes events created from Gmail

What’s changing

Starting May 30, 2024, the Calendar API will distinguish events created from Gmail. New and existing events from Gmail that are scheduled for a future date will:

Appear with a new event Type “fromGmail” instead of “default”.Include the email recipient as the organizer instead of “unknownorganizer@calendar.google.com”.New “fromGmail” filters for both Events.list and Events.watch will be available.

In Google Calendar clients events from email may be rendered slightly differently to regular events and show a link back to the original email:

Google Calendar limits edits for events from email:

Additional details

If you’re using the Calendar API, we recommend the following to help avoid any disruptions in your applications:

Ensure that your code does not apply restricted updates to events with the type “fromGmail”.Temporarily, updates on events with the type “fromGmail” are restricted to the properties reminders, colorId, visibility, status, and extendedProperties. Stay tuned to the Workspace updates blog for more information.Review your code if it filters by eventType for Events.list or Events.watch. Filtering by eventType “default” will no longer return events extracted from emails.
