USPS Merchant Returns API

The service provides expedited processing of shipping for returns of merchandise delivered via the U.S. Postal Service (USPS). Specifically, it augments service to merchants through the provider's Scan Based Payment program by allowing expedited processing of customer product returns with quick refunds of purchase price. By offering merchant-funded USPS return labels, sellers can encourage trial purchases and simplify interactions with customers. Each shipping label generated by the service carries an Intelligent Mail Package Barcode (IMpb) for automated package tracking.

API methods support submission of a return processing request with customer name and address, product specifications, and merchant account ID. The API responds with a fully formatted shipping label, USPS tracking number, and related processing information.
