USPS Shipping module

Hi,

I am having issues getting my UPSP Module to work?
I have an account with USPS.
Cube cart module setup is asking me to enter my user ID ,does that mean the to enter login name I use to access USPS??

Any help would be great.

No, you have to register with the development side of USPS. When the registration is complete, they will send you an email with the "DEVELOPER" Username and Password. Here is the main page for the developer apis:

Hope that helps!
