First, I apologize for any faux pas I might make. I didn't have time to read posts before making this first post - I'm in a desperate situation. I can't process orders.
Here's the thing:

I signed up for Paymentech as my credit card processor, and had set me up for Paymentech processing. I haven't been able to process an order yet - I keep getting errors. Tonight, I find out that I pay Paymentech, but somehow Authorize.Net does the Internet processing. So, switched me over to Authorize.net, but I'm still getting errors when I try to process.

Has anyone had this problem?

Thanks.

Hedon-

Please call tech support at 800-353-6582. Any tech there will be glad to help you out. Explain the situation you have with Authorize.net and Paymentech and inform them of what your site is so we can resolve this ASAP. Thanks!

Sabres00 - thank you for responding - it definitely improved my mood.

I did contact tech support, and they did help as much as they could. It did turn out to be a problem between Paymentech and Authorize.net. Each of them kept telling me the problem was on the other company's side (), until I kept complaining to this one tech person at Paymentech who finally gave me the key:

For anyone using Paymentech, who finds out that Authorize.net will do the processing, be sure to email Authorize.net support with these settings (it would seem to me Paymentech should have done this and made sure they were correct, but hey, that's just me):

PNS Merchant Number (aka Merchant Number) - this is 12 digits long
PNS Client Number - this is 4 digits long
Terminal Number - this is 3 digits long
Merchant MCC/SIC - this is 4 digits long

All of this information comes on a neat little sheet called the Authorize.net Set-up Sheet and/or you can call Paymentech and bug them until they give you this information.

Also, ask them whether you have "terminal capture enabled" and tell Authorize.net this too.

Hopefully this will help someone else from breaking out the Excedrin.

Hedon,

Thanks for the info... this will help future clients from jumping through the same hoops.
