Hi guys


I integrated Instant Payment Notification WITH direct_payment pro


No luck, but it gives always invalid response


Paypal_library


<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Paypal_Lib {

var $ipn_data = array();
var $last_error;
var $ipn_response;

var $CI;


// -------------------------------------------------------------------------------------------------------------
//assigning urls,providing constant values

function Paypal_Lib() {

$this->CI =& get_instance();
$this->CI->load->helper('url');

$this->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; //intialize paypal sandbox website url
