AI Not Booking

Hi everyone,

I’ve set up a Make flow to book appointments via the Cal.com API. The HTTP POST to https://api.cal.com/v2/bookings returns success every time — no errors at all.

The calendar is properly connected in Cal.com, my API key is valid, and the start time is correctly formatted (ISO 8601 with timezone). But: no booking appears in Cal.com or in my connected Google Calendar.

It looks like the booking works — but nothing shows up.

Has anyone experienced this? Could this be a calendar sync or API permission issue?

Thanks in advance!
