Hello community! I'm having an issue here and I'm about to throw in the towle and use another system different from Paypal because I have lost more than a day trying to use the same code they provide: <?php namespace Listener;
require('PaypalIPN.php');
use PaypalIPN;
$ipn = new PaypalIPN();
// Use the sandbox endpoint during testing.
$ipn->useSandbox();
$verified = $ipn->verifyIPN();
if ($verified) {
$response = "verified";
file_put_contents("test.txt", $response);
/*
* Process IPN
* A list of variables is available here:
* https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNandPDTVariables/
*/
} else {
$response = "negativo2";
file_put_contents("test.txt", $response);
}
// Reply with an empty 200 response to indicate to paypal the IPN was received correctly.
header("HTTP/1.1 200 OK");
