Does Calendly API support updating a user's default availability schedule directly

Hi Saurabh,

Javay here - from Calendly’s Developer Support team. Thanks for your question!

As of now, the Calendly API does not support updating a user’s default availability schedule (their overall "working hours") directly. You can retrieve (GET) a user’s availability schedule, but there is no public API endpoint to modify or update the user’s default weekly schedule at the account level. These changes must be made manually within the Calendly web or mobile app.

That said, there is an API endpoint that allows updating availability for specific event types tied to a user. You can use the
PATCH /event_types/{uuid}/availability_schedules/{schedule_id}
endpoint to adjust availability for individual event types, but this does not affect the user’s default overall working hours.

We understand how important this feature can be, and I will submit your feedback on your behalf to help highlight the demand for this capability.

If you need further help or have additional questions, feel free to reach out to our Support team anytime at support@calendly.com.
