  description: >-
    Legacy "bread-classic" REST API for managing Bread Pay BNPL checkouts.
    The Merchant API helps manage completed transactions and carts (which can
    also be created directly in the browser via the Bread JavaScript SDK), and
    the Shipping API exposes carrier and tracking number information on the
    transaction. Hosted by Bread Financial Holdings (NYSE: BFH).
