Editing Payment Module

Hello to All,

My merchant emulates authorize.net but requires that I use another URL to connect to for the payment.

In the authorize.net aim module that I find in my opencart install, I don't see any reference to the URL that it is connecting to. It seems that this variable is stored somewhere else.

Anybody can help me locate it ?

Thanks !

catalog/controller/payment/authorizenet_aim.php has a url in there
