View source for Configure your PayPal IPN script to notify ConversionRuler

If your cart already supports [[PayPal IPN]] then you'll need to customize your script to communicate directly with ConversionRuler using the '''custom''' parameter passed in [[Integrating PayPal Commerce Tracking|originally]].

An example, written in PHP to track order amounts and order numbers is:

 <nowiki><?php
/* This is your custom IPN processing file */
... regular IPN tracking ...
$custom = isset($_REQUEST['custom']) ? $_REQUEST['custom'] : null;
if ($custom) {
    $custom .= "&cramount0=" . urlencode($_REQUEST['mc_gross']);
    $custom .= "&crtext0=" . urlencode($_REQUEST['txn_id']);
    file_get_contents("https://www.conversionruler.com/bin/tracker.php?" + $custom);
}</nowiki>

Note the URL used to notify ConversionRuler is:

 https://www.conversionruler.com/bin/tracker.php

Which takes a few query string parameters:

* '''crsite''' - The Site ID to track (You may also use the name '''siteid''') '''Required.'''
* '''crcookie''' - The user's identification. ''Required.'' In this case, it's required, but normally it's passed by the browser and is not required.
* '''craction''' - The action code to record. ''Optional.''
* '''cramount0''' - The order amount. ''Optional.''
* '''crtext0''' - The order number. ''Optional.''

Note that you must properly URL-encode any values you pass to this script.
