Paypal Ipn Problem

Recommended Posts

I successfully implemented paypal ipn on my website, I tested it on the paypal sandbox and everything worked. Then I changed the url from https://www.sandbox..../cgi-bin/webscr to https://www.paypal.com/cgi-bin/webscr. This should be standard procedure and everything should work fine.

Once again, when using the sandbox provided by paypal, there are no problems.

 

Now a few of my customers tried to buy things and nobody got there items. In my database I log everything and I logged this error:

http error=Unknown SSL protocol error in connection to www.paypal.com:443

 

I use paypal ipn for the payment, underneath will be the ipn.php (ipn call back script that paypal will post variables to when a payment has been done)

//Original source: https://cms.paypal.com/cms_content/US/en_US/files/developer/IPN_PHP_41.txt
//Modified sample code by Codex-m: http://www.php-developer.org
//WORKING DEMO HERE: http://www.php-developer.org/paypal_ipn_demo/
//Use your Paypal Sandbox buyer account to test.
$req = 'cmd=' . urlencode('_notify-validate');
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
//NEW CODE: using Curl instead of fsockopen
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.sandbox.paypal.com'));
$res = curl_exec($ch);
//assign posted variables to PHP variables
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$account=$_POST['custom'];
$productname=$_POST['item_name'];
$txn_type=$_POST['txn_type'];
$trans_id=$_POST['transaction[0].id'];
$trans_id_2=$_POST['transaction[0].id_for_sender'];
//Check if any error occured
if(curl_errno($ch)) { //HTTP ERROR occurred
//Log error to database for troubleshooting
$log='http error='.curl_error($ch); //Here the error message gets build
db_write($log); //Here it gets written to the database
} else {
//NO HTTP ERROR OCCURRED, CLEAN
//CHECK IF VERIFIED
if (strcmp ($res, "VERIFIED") == 0) {

Unfortunately, an "Unknown SSL protocol error in connection to www.paypal.com:443", with "Unknown" being the keyword, error is rather difficult to decipher.

 

You say "a few customers"... so not all customers, correct?  If so, then it might just be a temporary issue with Paypal.  Have you run a test purchase yourself to verify all systems are a go?

Sorry I meant a few of my customers as in, I got 100% customers and 10% of them bought something using paypal. Every customer using it got the problem.

Was it spread out over a period of time?  Or was each purchase made relatively close to eachother, ie. all happened within an hour.

 

And, have you tried again since?

I'd ask Paypal support on this one, to be honest. Seeing as it's an HTTP error they're the ones who're best equipped to help you out.
