After you have your Affiliate Software account setup the integration into Google Checkout is really easy. Simply follow the steps below.

We have made it easy to integrate your affiliate software with your shopping cart or gateway by following the instructions below. If you would like our technical team to integrate the software for you then you can sign up for our Managed Integration option.

Step 1. Add Code to your Landing Pages

Move the following code to your landing page. The landing page is the main page of your web site where web users will end up after clicking on the affiliate link.
Please Note: Where it says http://yourcompany.myomnistar.com, please replace that URL with the actual URL of where your software is installed.

<script>
var resource = document.createElement('script');
resource.src = "http://yourcompany.myomnistar.com/track.js";
var script = document.getElementsByTagName('script')[0];
script.parentNode.insertBefore(resource, script);
</script>

Step 2. Add the Sale Tracking code

To integrate sale tracking with Google Checkout, you should do the following steps.

1. You need Google Checkout plugin from Google API.

2. Log in to your Google Checkout merchant account. Go to Settings panel. Now select Integration from left menu.Next you must insert URL https://yourdomain.com/your-notify-file.php into "API callback URL: " textbox. Last thing, is to select Notification as HTML radio button from "Callback method: " group. Do not forget to save your settings.

3. Go to your your-notify-file.php and put the following code in this file.

<?php if($_REQUEST['google-order-number'] )
{
$amount=$_REQUEST['authorization-amount'];
$ordid=$_REQUEST['google-order-number'];
?>
<script>
function hideIF() {
document.getElementById('IF').style.display = '';
}
function getSaleInfo() {

document.getElementById('st_code').innerHTML='<iframe src="https://yourcompany.myomnistar.com/salejs.php?amount=<?=$amount?... $ordid?>" alt="" id=IF width=50 height=50 border="0" frameborder="0" onload="hideIF()">';
}
window.onload = getSaleInfo;
</script>
<div id="st_code"></div>
<?php }?>

That's it. You are now integrated with Google Checkout.

Step 3. Test

Now you should test the affiliate program by creating a test user from your user area. Once you create a test user, sign in as that test user and copy the link under where it says "Link To Promote" and then click on the affiliate link that is shown. Next you should go through the entire process of completing an order with your shopping cart or order form by using a test credit card. Once you go through the process then you can make sure the test user received credit for the sale.
