After working on a different zencart store with authorize.net payment, I noticed something in the setup that I thought would help my situation here. I didn't set a hash value in the authorize.net account, and also left it blank in the zencart setup. Seemed to work just fine. Granted, this new store was not hosted on godaddy, so not everything about the two situations were completely equal...

So I contacted Authorize.net help this morning, hoping that if I could just get the hash value on the account cleared, it might solve the situation. No such luck. They're not able to do that, and the guy from live help said he couldn't tell there was a value in our account (?). I then asked if we could just have the account reset, and he said he couldn't do that either.

The only pertinent information I really received (other than "sorry, we can't do that") was that the md5 hash value needed to be cleared from the store engine sending the data over. I can't actually tell from the logs that zencart does that (looks like it's only used on the return log from authorize.net).

All that to say, I'm now even more confused, and back to square one. Does anyone have ideas for what a reasonable next step might be? Thanks in advance.
