This SDK is a PHP Library for access to the ShipStation API. The API enables you to feed orders, customers, and products into ShipStation, and query on a wide variety of data. It is a web-based shipping solution that streamlines the order fulfillment process for online retailers. ShipStation integrates with USPS, UPS, and FedEx for retrieving rates, creating labels, and more.
Dataplug is for businesses that ship using multiple carriers and need to manage which orders should be shipped via which carrier. The legacy solution of course is manual entry: sort the orders according to carrier and then enter them into the different carrier websites. Beyond costing time and money, it creates a customer service nightmare when a customer wants to track a package. "Which carrier did we send that on, again," the operator might be wondering. Dataplug finesses all that, right down to the tracking, done all in one place--and customers can go to your site and track packages themselves.
