  title: CDK Global Book Service Session
  summary: Create a booking session, discover an available store and slot, and book it.
  description: >-
    Walks the full online service booking flow for a dealership. The workflow
    creates a booking session for a vehicle and customer across one or more
    stores, queries the stores that have availability, queries the open
    appointment slots for the chosen store, and books the final slot to confirm
    the appointment. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
