  title: Mews Service Availability to Reservation
  summary: Resolve a service, check category availability, then book if space exists.
  description: >-
    An availability-aware booking pattern. The Connector API services/getAll
    action resolves the bookable service, services/getAvailability returns the
    free counts per resource category across the requested time units, and the
    flow branches: when availability exists a reservation is created with
    reservations/add. Each step inlines its action-style POST body with the
    ClientToken, AccessToken, and Client authentication fields Mews requires so
    the flow reads and runs without opening the OpenAPI description.
