  title: Tango Explore Catalog and Choice Product
  summary: Browse brand categories, list Tango Choice products, and fetch one Choice product's detail.
  description: >-
    A catalog-discovery pattern for building a reward picker. The workflow lists
    the available brand categories for filtering, lists the Tango Choice products
    on offer, and then fetches the full detail of a specific Choice product by its
    UTID. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description. Authentication
    uses the platform's HTTP Basic credentials declared by the basicAuth security
    scheme; those credentials are applied at the transport layer and are not
    request parameters.
