CyberSource integrates using SOP callback even if the callback is used by other system (e.g. shopping cart).

1.

Setup your custom variable number

Right after you activate CyberSource plugin you need to setup number ofcustom variable, which will be used to transfer tracking data to PAP.Login to your merchant panel. Go to menu Start->Plugins. Now click Configure button in CyberSource plugin item. Here you can set up numer from 1 to 4. Default is 1.

2.

Edit button forms

Now add the following code into EVERY CyberSource button form.

<input type="hidden" name="merchantDefinedData2" value="" id="pap_dx8vc2s5">
<script id="pap_x2s6df8d" src="http://URL_TO_PostAffiliatePro/scripts/notifysale.php" type="text/javascript">
</script>

Name of item must be merchantDefinedDataNUMBER. Where NUMBER is number of custom field which you configured in step 1.

3.

Integration 2

Now the SOP callback is pointed to your script. This callback has to beforwarded also to PAP cybersource.php script, which url is http://URL_TO_PostAffiliatePro/plugins/CyberSource/cybersource.php.In case, your cybersource processing script is in PHP, you can use followingcode to accomplish that. You can place it at the beginning of yourprocessing file.

/* PAP integration */
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, "http://URL_TO_PostAffiliatePro/plugins/CyberSource/cybersource.php");
 curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
 curl_exec($ch);
/* end of PAP integration */

This will ensure that whole SOP callback will be forwarded without affecting your original script

This is all that is required. Now whenever there's sale, CyberSource willuse its SOP function to call our sale tracking script, and system willgenerate commission for the affiliate.
