The service allows applications to integrate the provider's E-Ship Web Services to estimate delivery cost and time and to complete shipping documentation. It implements rules and restrictions governing package shipping to allow an e-commerce site or retailer to quote delivery terms and arrange customer shipping upon completion of a purchase.
API methods support submission of a shipping location and delivery address, along with package contents and other details, to generate an estimate of delivery time and cost. Methods then allow booking of the shipment, completion of shipping documents, and scheduling of pickup. The API also supports tracking of packages en route and processing of returned merchandise.
