List available times

List available times

Returns the open start times of one event type within a range of up to 31 days, each with its booking page URL.

Pass the event_type URI, start_time and end_time. The range can't start in the past or span more than 31 days, and the results aren't paginated. Offer the prospect a few of the returned times, then book the chosen one with meetings-create_invitee or POST /invitees.
