What is the Shipment Calculator?
At its core, the Shipment Calculator is an Application Program Interface (API). The Shipping Calculator provides a mechanism for other programs, such as shopping carts, to determine an estimated shipping cost for an order. The Shipment Calculator can be thought of as the middle ware between an application that needs shipping costs and shipping vendors such as FedEx™, UPS™, and USPS™ that provide shipping. How does it work? A list of items, along with the ship to/from addresses, are passed to the API and shipping manifests are returned. The manifests detail the shipping vendor, type of shipping service, packages, and items in each package. The Shipping Calculator dynamically determines a recommended packaging of "co-packable" items. Co-packable means multiple items may be included in a single box.
