USPS Resources
Just looking for info on the USPS API? Here is a list of links that are helpful:
- USPS Web Tools APIs - these are a collection of public, SOAP/XML USPS APIs. They do not offer postage purchasing, so you can't actually ship anything with them, but they do offer the following individual APIs:
- USPS Web Tools API Docs - These are the docs for the SOAP/XML APIs offered by USPS. No client libraries are offered, unfortunately. USPS Web Tools Docs
- Register - Once you're ready to begin testing, you'll need to register for a USPS username. USPS Web Tools Registration
- Production Access - once you're ready for production access you'll need to email uspstechnicalsupport@mailps.custhelp.com with "Please move User ID {Insert your Web Tools User ID here} to the production server." in the Subject. You can find more details at the Web Tools Developer Resource Center.
