  title: Mews Post Room Service Order
  summary: Resolve a guest's reservation, then post a point-of-sale order to it.
  description: >-
    The Mews ancillary-revenue pattern. The Connector API reservations/getAll
    action resolves the reservation and exposes its guest account id, then
    orders/add posts a point-of-sale order (products and custom items) against
    that account, linked to the reservation. 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.
