Logging PayPal Response Codes

On a proper setup this should never happen. So I would like to understand the reason of the failure better.

When a transaction fails (if PayPal doesn’t accept the card), it should show an error with a response code. That response code will be helpful to figure out what and why it is failing.

What response code do you get for the transaction failure?

Thank you for the prompt response.

I am not sure if the customer is seeing a response code, but the order in admin just shows a couple of notes that say…

Paypal Credit Card Payment Failed with message: ‘This transaction cannot be processed.

So I guess that was what I was asking; are the response codes logged anywhere?

Just looking at our PayPal console, and there are no failed IPNs there to match the failed transactions in WooComm.

So it appears that occasionally the requests are not being sent.

Can you think of anything that may be blocking our requests to PayPal?

Thanks again.

with PayPal pro, the transaction doesn’t even go forward if the card was declined by PayPal. So looking at IPN won’t help.

I don’t know if PayPal just blocks the request when it is made from your server (due to the server not responding correctly to PayPal’s response) or PayPal is just not accepting that card for whatever reason.

What happens if you do lets say 5 test transactions with a valid card. Do those transactions fail at all? If none of those fail then the card is likely the problem.

Also, ask PayPal support if your merchant account has permission to access ALL types of cards. Otherwise if a customer is trying to use a card that your merchant account doesn’t have permission for, it will fail.

I have not been able to trigger a failure at all with a valid card.
And we have not seen a failure for about the last 10 transactions now.

Just added a bit of code to add the error code (L_ERRORCODE0) to the order notes, so next failure I will have some more information.

Thanks, and I will report back.
