DrByte - Thank you

In your post, you mention that there will be a 'return url' that I give my CC processor. Yes - there is a field for me to send them the return path. You're spot on.

I already used the authorize.net module as the one to go from. I'm confused about how to get the payment page to my CC provider without going to the confirmation page. It seems that the way the authorize.net module works, is that on the payment page, you type in the CC info. Then you press the zencart button to go to a confirmation page which will display all of the options back to the customer. There is a hidden form set with all of the values, including the customers CC info (under an SSL certificate mind you). And THAT submit button is directed off to my CC provider.

I don't see how to get the 'Payment Method' page to go straight to my CC provider, without 'hacking' it to do so. but could confuse customers potentially.

Please understand, I'm definitely NOT trying to save any customer CC info. I'm trying to work within the framework of zencart and be as safe and secure as possible in this. Any advise is greatly appreciated.

Where I am, just as an FYI -
I have the module all built wherein on the 3 of 3 order confirmation page, that form will post to my CC provider and they are given the return url. My original question is where do I sent them. If that's checkout_process, awesome. That's where I'll send them.

Is it OK to have the customers CC info for only that one iteration of a submit, the CC info is only in a session variable - is this safe?
