Hi everyone,

I'm running group events where participants book through Calendly, and their information is stored in a Google Sheet. As confirmed by Calendly support, Group Event bookings do not automatically add invitees to Google Calendar.

To work around this, I use Zapier to add each registrant to a shared Google Calendar event. While this technically works — and the attendee is successfully added — it causes a problem:

Every time a new person is added, Google Calendar sends an "Event Updated" email to all previous attendees, even though the only change is the addition of a new guest.

I've tested this with both manual additions and Zapier automation, and the behavior is consistent.
I've also tried using the sendUpdates=none parameter via the Google Calendar API, but it hasn't resolved the issue.

My question:
Is there any way to prevent Google Calendar from sending these update notifications when new guests are added?
Ideally, I want attendees to receive their initial invite but not get updated emails each time someone else is added to the event.

Any insight or workarounds would be much appreciated!

Thanks in advance.
