Book a meeting

Book a meeting

Books an invitee into an open time on an event type and returns the invitee with links to cancel or reschedule.

Pass the event_type URI, a start_time in UTC taken from the event type's available times, and the invitee's email, timezone and name (or first_name). Include location with its kind only when the event type sets a location, answer its required questions in questions_and_answers with the exact question text, and add tracking UTM parameters to attribute the meeting. Calendly sends the calendar invite and notifications as if the invitee had booked on the page. Needs a paid plan (Standard or above): the Free plan gets a 403.
