The Appointment API provides endpoints for interacting with the appointment booking application. Use this API to book and reschedule appointments, check available appointment slots, and fetch appointment booking configuration details.

Before using this API, the Appointment Booking Configuration and Service Configuration must be setup. In addition, a task for which the appointment is being booked must already exist. For additional information, see Configuring Appointment Booking.
