What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

Action
Update event type availability scheduleReplaces a single host's availability schedule on a Calendly event type with explicit date rules (full overwrite). Built for CalendarConnect: push real Mindbody bookable slots into Calendly so only MBO-bookable times are offered. CRITICAL: the host is targeted by the NESTED availability_rule.user — a top-level user alone is silently ignored and Calendly replaces the OAuth token owner's schedule instead. Always verify stored_user equals the requested host before trusting the result. For round-robin events, call once per host.

Can my AI client use Calendly and FreshBooks without building an automation?
