Book a meeting

Books start, which must be one of the slots from get_available_slots. Free events are confirmed at once, unless the event type has requiresApproval: then it's a request (status=pending_approval) that holds the time until a host approves or declines it, and the invitee hears either way by email. Nobody answering by its start (holdExpiresAt) lets it lapse. Tell the human it isn't confirmed yet. Paid events return status=pending_payment and a paymentUrl. Give it to the human to pay before holdExpiresAt, or the slot is released. Once confirmed, the event is added to the host's calendar if they connected one, and the invitee gets a confirmation email with a calendar file (.ics). Keep manageUrl and token: they are the only way to view, reschedule or cancel later. 409 slot_unavailable says why the time can't be booked and lists the nearest open times. The result's when is the start in the invitee's time zone, to tell them.
