An appointment ID is a **String** object that represents the appointment. Use the [**ShowAddAppointmentAsync**](http://msdn.microsoft.com/library/windows/apps/dn297256) API to obtain an appointment ID of the appointment to add. Use this appointment ID with the [**ShowReplaceAppointmentAsync**](http://msdn.microsoft.com/library/windows/apps/dn297283) or [**ShowRemoveAppointmentAsync**](http://msdn.microsoft.com/library/windows/apps/dn297269) API to update or remove the appointment.
