  description: >-
    The shopping-cart checkout path through the Service Catalog API. The
    workflow adds a catalog item to the current user's cart with a quantity and
    variable values, retrieves the cart to review its contents, and submits the
    cart as a single service catalog request, returning the request number. The
    Service Catalog API wraps the cart item and order result under a result
    object. Every request is written inline.
