The Saia API helps this first class less-than-a-truckload (LTL) carrier deliver by giving developers access to tracking information inside their applications. Rate quotes and pick up scheduling are also accessible. The API uses SOAP and XML, and is implemented using Microsoft's .NET Framework.
It's not enough to print stamps off your printer any more. What shippers really want is what the SOAP-based Stamps.com API does: integrate that function of printing postage into your own web-based ecommerce or web hosted applications to speed up the shipment of orders out the door. With the API you can do much more than calculate postage and print stamps. You can clean addresses and track packages, among other tasks.
