  title: CDK Global Reschedule Service Appointment
  summary: Read an existing appointment, update its date/time, then confirm the change.
  description: >-
    Reschedules a vehicle service appointment by first reading the existing
    appointment to capture its current services, posting an update that carries
    the new date/time while preserving the requested services, and finally
    reading the appointment back to confirm the new time. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
