I think QS support did that for me when I went to 5 and I don’t recall having to have anything from my UPS account except our account number.
They also have a demo setup for UPS and FedEx that allows you to ship in a sandbox/test without actually generating valid tracking numbers. I found the FedEx setup in the online help
Quick Ship but can’t find the UPS demo account information except that it uses https://wwwcie.ups.com rather than onlintools.ups.com. one of them also requires a certain address, but i can’t find that info.
