goemerchant gateway

Hello i have just started using open cart and everything is going pretty swell thanks. The only problem i have ran into is my gateway. I use goemerchant.com and you dont support that. Now they claim (goemerchant) that if i can use authorize.net and they have a plug into that using a eximulator. here is a link http://www.goemerchant.com/techsupport/gateway.htm of what they said i can use. is there anything now you have i can plug this into if not will i have to figure out something else? Thanks in advance

There are plenty of people in the forums who would probably build you a payment module - perhaps post your requirement in the commercial forum.

You can modify the existing Authorize.net payment module located at:

opencart/catalog/controller/payment/authorizenet_aim.php

CHANGE
$url = 'https://secure.authorize.net/gateway/transact.dll';
TO
$url = 'https://secure.goemerchant.com/secure/g ... teway.aspx';

Now just enable the Authorize.net AIM payment module under extensions. For your Login ID use your Goemerchant supplied Transaction Center ID. Your Transaction Key will be the Goemerchant supplied gateway id.
