I have not been able to get the USPS shipping module to work and I was wondering if anyone has an advice. USPS sent me several URLS to the production server, but I am not sure where they should be entered. Here is the email they sent me:

[FONT=Times New Roman]Thank you for contacting us. Congratulations on completing your testing using the U.S. Postal Service's Internet Shipping Application Program Interfaces (APIs). [/FONT]
[FONT=Times New Roman]Your profile has been updated to allow you access to the Production Server.[/FONT]

[FONT=Times New Roman]1. The Production Server URL is: http://production.shippingapis.com. For APIs calling the secure server, the URL is https://secure.shippingapis.com.[/FONT]
[FONT=Times New Roman]2. There is a line of code that refers to "shippingapitest.dll". You'll need to remove the word "test".[/FONT]

[FONT=Times New Roman]If you are using third party software and need assistance, please contact the vendor of the software. They should be able to assist you in obtaining live information using our APIs. [/FONT]

[FONT=Times New Roman]I am using version 1.2.7 of Zen Cart...which files do I add this info too?[/FONT]

[FONT=Times New Roman]Thanks![/FONT]
