how do I test and integrate USPS Web Tools
How do I test before moving to the USPS production server?
Here is the info they provide after signing up.
Your Web Tools User ID, shown above, is required to test and integrate USPS Web Tools APIs.* With this ID, you may begin sending calls to the test server.* Depending on the API, the address to the test server is either ShippingAPITest.dll or ShippingAPITest.dll.* Use this information in combination with your User ID and your XML string to send a request to the USPS servers.* For more details, refer to the programming guides (located at webtools) for the specific API you are integrating.
A sample test request would look like: "http://testing.shippingapis.com/ShippingAPITest.dll?API=[API_Name]&XML=[XML_String_containing_User_ID]"
When you have completed your testing, email the USPS Internet Customer Care Center (ICCC).* They will switch your profile to allow you access to the production server and will provide you with the production URLs.
