I'm hoping someone can help me out. I installed the payza payment module that I downloaded from payza. It works except after you pay it takes you right back to the payment page and doesn't record the order in admin.

I contacted payza and they said this:

For Alert URL, enter the URL of the location of your IPN Handler.

So my question is what is my IPN Handler url ?

I tried the one that I know paypal uses ( ipn_main_handler.php )

That did not work.

I appreciate any help.

I'm using zencart version 5.5e with no other plugins that would affect this.
