USPS Error: RateV3 is not a valid API name for this protocol
Sample Error
API Authorization failure. RateV3 is not a valid API name for this protocol.
Solution or Workaround
You may receive this error message if you enabled "Test Mode" on the PDshop USPS settings page.  The USPS no longer supports Test Mode for Version 3 of their API.  As a result, you should turn off "Test Mode".  If you receive a message about not having permission to use this server, contact the USPS to have your Web Tools User ID switched to their "production servers".

You will receive the above error if your Web Tools User ID has not been given permissions to use their API.  

Email the USPS Internet Customer Care Center (ICCC).  Ask them to switch your profile to allow you access to the "production server".

The ICCC is staffed from 7:00AM to 11:00PM Eastern Time.
