Welcome to the PyUSPS_WebTools wiki!

I recently acquired a client that ships their packages via the USPS (United States Postal Service), and they were interested in adding some of the web tools provided by the USPS to their order fulfillment system. After taking some time to peruse the utilities that the USPS makes available to its customers, I implemented some code for my client and decided to expand upon that code and provide a more general interface for use by the open source community. There are some “allowed use” requirements that must be followed, and use of the USPS web tools requires registration with the USPS itself, so there are some restrictions on what can be provided here. However, once someone registers with them and completes the required testing steps, this library should provide a simple yet elegant way in which the end user can communicate with the USPS web services.

Please note that at the current time this is under constant development and is not yet ready for public use. Once a working version has been completed, a notice will be posted here. Though I expect to be the unique developer involved with this project, I welcome others to contribute to the project. All I ask is that contact be made before any contributions are made to the codebase.

The initial version of this utility library is being designed to work with the following APIs:

• Address verification/correction


• Delivery confirmation / shipping label generation


• Tracking confirmation
