Bread Classic Merchant API
Legacy "bread-classic" REST API for managing Bread checkout transactions, carts, shipping (carrier + tracking) and capture/refund/cancel actions from the original Bread BNPL product, still documented at docs.breadpayments.com for merchants on the prior integration. The Merchant API helps manage completed transactions and carts, which can also be created directly in the browser via the Bread JavaScript SDK.
