Check availability times
Open times on one date for an appointment type.
GET https://cotlet.dev/api/v1/acuity-scheduling/appointment-types/{appointment_type_id}/availability-times/check
read
Returns the open start times on one date for the appointment type, as ISO timestamps with offset, matching what clients see on your scheduler. To move an appointment to a time that overlaps its own slot, pass its ID in ignore_appointment_ids so the current slot counts as free.
