  title: Mews Find or Create Customer
  summary: Search for a guest by name and create the profile only when none exists.
  description: >-
    A guest-deduplication pattern for Mews. The Connector API customers/search
    action is run against a name, and the flow branches: when a matching profile
    is returned the existing customer id is reused, and when no match is found a
    new profile is created with customers/add. Each step inlines its POST body
    with the ClientToken, AccessToken, and Client authentication fields Mews
    requires so the flow reads and runs without opening the OpenAPI description.
