How to Start a NEW PAYMENT MODULE.

Hi,

How could one start a new Payment Module.

I would like to make a module similar to Authorize.NET AIM (where the person does not have to leave the site).

The module I would like to make is for InternetSecure using Merchant Direct.
One of the cool things I want to do is take advantage of their RECURRING PAYMENTS.

I know NOTgoddess created the AMAZING Merchant Link module (but that takes the customer out of the site).

If you could give me some pointers on how to get started that would be great!

THANKS!!!!!!!!!!!!!!!!!!!!!

Get the deveoper documentation from the gateway and compare their method for connecting to AuthorizeNet or LinkPoint.

But what are the basics in Zen-Cart

The Wiki, seems to be empty:

Currently, I am modifying the Authorize.NET AIM module changing the $description variable for the orders. I don't really understand all the code yet... so I was hoping a blank template will help me understand where all the peices go.

AFTER:
$description .= $order->products[$i]['price'] . '::' . $order->products[$i]['qty'] . '::' . $i . '::' . $order->products[$i]['name'] . '::{US}|';

Doesn't seem to be reading it right...

Thanks for your help.

I've got the Developer documentation:

Seems the easiest way is to modify the Authorize.NET AIM module since it can work with Merchant Direct.
