The Java SDK for AfterShip enables developers to integrate their Java applications with the AfterShip service, to request information on shipment for their users. A number of different couriers are supported by the AfterShip service.
DropBuddies, the Postmates of Nigeria, launched an API that allows local businesses to include courier services directly within their apps. Without leaving the integrated business' app, users get a delivery quote, ETA, and book a delivery. Once booked, users can track shipments through delivery.
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.
