Jam Affiliate Integration

Hi, i have a queery. 

Im going to shortly attempt to integrate JAM AFFILIATE software with my dolphin installation.

The JAM instructions to integreate with any PHP script are:

1. Add this code to the THANK YOU page of the script? (The RETURN Page after payment)

<?php 
file_get_contents("http://www.yourdomain.com/affiliates/sale/amount/$AMOUNT/trans_id/$ORDERID");
?>

2. Change the $AMOUNT and the $ORDERID to reflect the script ie AUTO SCRIPT

Do you have an idea what i replace $AMOUNT and $ORDERID with?
and WHAT IS THE PAGE I NEED TO ADD THE CODE TO?

Then if someone sends a buyer to the script it can be tracked successfully. (IN JAM)

Hope this is understandable Thanks

PS Full jam integration instructions here:

 Try the following:

         $aResult = $oProvider->finalizeCheckout($aData);
        if((int)$aResult['code'] == 1) {

$aOrder = $this->_oDb->getPending(array('type' => 'id', 'id' => $aResult['pending_id'])); 
file_get_contents("http://www.yourdomain.com/affiliates/sale/amount/{$aOrder['amount']}/trans_id/{$aOrder['order']}"); 

            $this->_oCart->updateInfo((int)$aResult['pending_id']);

            if($oProvider->needRedirect()) {
                header('Location: ' . $this->_oConfig->getReturnUrl());
                exit;
            }
        }
