book_appointment

Behavior, inputs, outputs and permissions for book_appointment.

Reviewed · 2026-10-06 / Ridian

This reference is generated from the published tool contract.

Books a slot of an appointment type for another person (the booker). Ridian writes the event into the host’s calendar and emails the booker a confirmation with a link to reschedule or cancel. Use a start time returned by find_booking_slots. Send a stable request_id; repeating it returns the same booking instead of booking twice. Confirm name, email and time with the user first.

Granted scopes, accounts, calendars and visibility rules limit access. Workspace administrators do not automatically gain access to other users’ accounts.

Check the tool result for errors. Do not blindly retry writes after a timeout. Check the current resource or send status first.
