USPS Active Credentials
I have been having this very same problem. I have read all the post in this thread and followed the suggestions and receive a message from USPS just yesterday with was suppose to be the proper URL to work with PowerStore to make the Shipping feature in PS3 work.
It does not.
Since this Thread was last posted to on March 20, 2010.
Has there been any further work on this matter by Users of this feature?
Has WebAssist come up with a fix or work around for this problem?
In addition, I would like to know if this problem is just happening to those of us that are using PayPal Express? In other words, are the Users of PayPal Payment Pro having this problem with USPS?
