Set ipnNotificationUrl variable in PayPal - php

Question

I'm trying to use the PayPal AdaptivePayments API and I'm trying to set the url for paypal IPN which is supposed to be "ipnNotificationUrl" but I don't know where to add it in the request.
Here is my code:
ini_set("track_errors", true);
//set PayPal Endpoint to sandbox
$url = trim("https://svcs.sandbox.paypal.com/AdaptivePayments/Pay");
/*
*******************************************************************

//PayPal API Credentials
$API_UserName = "sbapi_1287090601_biz_api1.paypal.com"; //TODO
$API_Password = "1287090610"; //TODO
$API_Signature = "ANFgtzcGWolmjcm5vfrf07xVQ6B9AsoDvVryVxEQqezY85hChCfdBMvY"; //TODO
//Default App ID for Sandbox
$API_AppID = "APP-80W284485P519543T";
$API_RequestFormat = "NV";
$API_ResponseFormat = "NV";
//Create request payload with minimum required parameters
$bodyparams = array ( "requestEnvelope.errorLanguage" => "en_US",
"actionType" => "PAY",
"currencyCode" => "USD",
"cancelUrl" => "http://www.paypal.com",
"returnUrl" => "http://www.paypal.com",

);
// convert payload array into url encoded query string
$body_data = http_build_query($bodyparams, "", chr(38));
try
{
//create request and add headers
$params = array("http" => array(
"method" => "POST",
"content" => $body_data,
"header" => "X-PAYPAL-SECURITY-USERID: " . $API_UserName . "\r\n" .

));
//create stream context
$ctx = stream_context_create($params);
//open the stream and send request
$fp = #fopen($url, "r", false, $ctx);
//get response
$response = stream_get_contents($fp);
//check to see if stream is open
if ($response === false) {
throw new Exception("php error message = " . "$php_errormsg");
}
//close the stream
fclose($fp);
//parse the ap key from the response
$keyArray = explode("&", $response);
foreach ($keyArray as $rVal){
list($qKey, $qVal) = explode ("=", $rVal);
$kArray[$qKey] = $qVal;
}
//set url to approve the transaction
$payPalURL = "https://www.sandbox.paypal.com/webscr?cmd=_ap-payment&paykey=" . $kArray["payKey"];
//print the url to screen for testing purposes
If ( $kArray["responseEnvelope.ack"] == "Success") {
echo '<p>' . $payPalURL . '</p>';
}
else {
echo 'ERROR Code: ' . $kArray["error(0).errorId"] . " <br/>";
echo 'ERROR Message: ' . urldecode($kArray["error(0).message"]) . " <br/>";
}
/*

If ( $kArray["responseEnvelope.ack"] == "Success") {
header("Location:". $payPalURL);
exit;
}
else {

echo 'ERROR Message: ' . urldecode($kArray["error(0).message"]) . " <br/>";
}
*/
}
catch(Exception $e) {
echo "Message: ||" .$e->getMessage()."||";
}
Thanks a lot!

It should be in $bodyparms array:
"returnUrl" => "http://www.paypal.com",
"ipnNotificationUrl" => "http://www.baseem.com/ipnhandler.php",
