  title: Ariba Guided Buying Browse Shop Catalog
  summary: Open a shop, get a typeahead suggestion, then list the matching catalog items.
  description: >-
    A three-step guided shopping flow over the Public Catalogs Shop API. It first
    opens a shop with its items and facets expanded, then runs a typeahead search
    with a partial term to obtain a refined suggestion, and finally lists the
    catalog items matching that suggestion. Together these steps walk a buyer
    from an empty shop to a concrete set of purchasable items. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
