PaypalProUK CVV2 Mismatch

PaypalProUK CVV2 Mismatch

Hi,

We've converted our cart to PaypalPro UK. The Express Checkout areas work fine. However, we cannot seem to get the direct pay by credit card to work properly. When entering a valid credit card number, I'm receiving a "CVV2 Mismatch" error. I've confirmed that the CVV2 is correct.

Could I send the checkout files and have someone look @ them? Also, let me know the additional information I should provide. I'm sure there's something I'm overlooking here.

Thanks in advance.

When you are getting this error is it just the regular error message that is displayed by default on the checkout failure page? If so the reason for the failure may be something different. In order to determine why it is failing we will need to be sure of the specific error you are getting.

If you do not have the debug code on your checkout failure page you should add it in then do a test and let us know what it comes back with. Add the following code to your checkout failure page:

php:
<?php  

if(!session_id()) session_start();   
echo(
"Direct Pay Full Request :<br />");  
echo(
"<code>".isset($_SESSION["PP_DirectPayment_postedValues"])?$_SESSION["PP_DirectPayment_postedValues"]:""."</code><br /><br />");  
echo(
"Direct Pay Full Response :<br />");  
echo(
"<code>".isset($_SESSION["PP_DirectPayment"])?$_SESSION["PP_DirectPayment"]:""."</code><br /><br />");
?>

Thanks for responding Eric. I placed your debug code on the checkout failure page and i get nothing:

Your transaction could not be completed. ***************************************************
Direct Pay Full Request :
Direct Pay Full Response :
****************************************************

I also added this code:
<?php echo(PP_PayProUK_Result("Full Response")) ?>
and I receive:
RESULT=114&PNREF=<PaypalUK Vendor>&RESPMSG=CVV2 Mismatch: 15004-This transaction cannot be processed. Please enter a valid Credit Card Verification Number.&AVSADDR=X&AVSZIP=X&CVV2MATCH=N&IAVS=N

The Payment Gateway is Paypal Pro UK.

Sorry about that, I should have checked the debug code and made sure it was using the proper UK values. The debugging code that you did add seems to be giving you the cvv error directly from PayPal.

Have you tried this with any other credit card? The code that is used to process the transaction from PayPal does not set these error messages directly, it just gets the full response from the PayPal API and parses it for the error messages. So it is PayPal that is telling you the values are bad. If you could test this with another card it might help to determine if this is an issue always with the current setup or if the error is specific to the card you are testing with.

If PayPal does not like the cvv value you are using for that card you would need to contact them for clarification.

Hi Eric!

Thanks again for your assistance. I was able to checkout using a VISA credit card. The original card was a VISA checkcard. Do you know of any issue with Paypal UK processing U.S. Visa checkcards? I will certainly check with Paypal as well. :)

As far as I know a valid credit card should pass validation regardless of the type of card. This is at least the way that it works here in the US. It is possible that there could be some other checks that are occurring for the card, like a geographic restriction based on where the card was issued. You should definitely get in touch with PayPal to get a more specific reason for the checkcard being rejected on the cvv value. If you find out any additional info on this please post back here with it so others can benefit from the knowledge.
