  title: Mews Record External Payment
  summary: Locate a reservation's guest account, then record an external payment.
  description: >-
    The Mews external-settlement pattern. The Connector API reservations/getAll
    action resolves the reservation's customer id, then payments/addExternal
    records a payment that was processed outside Mews (such as cash or an external
    terminal) against that account. 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.
