  title: Mews Add Product to Reservation
  summary: Resolve a product on a service, then attach it to a reservation.
  description: >-
    The Mews upsell pattern. The Connector API products/getAll action lists the
    products available on a service, and the flow branches: when a product is
    found, reservations/addProduct attaches it to the reservation for a count and
    interval. 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.
