PayPal Payment Notification Issue

[XtremeTech]

Hello,

 

I am having 1 issue with receiving PayPal payment notification details. Once the customer pays, PayPal sends the customer back to my website and shows the invoice to the customer, as it should, but at the top it shows Unpaid and it shows not transaction details at the bottom of the invoice and it shows no payment in my transaction screen, but there is a title bar across the invoice stating the payment was successful.

 

So how does the invoice show Unpaid, logs no payment in WHMCS, but shows a bar across the invoice saying it was successful? The payment was successful, so why is WHMCS not retrieving the transaction details and showing the invoice as being paid? All my PayPal settings are correct, I even have the API login info there and the redirect back to WHMCS is set. Can any advise on a setting I'm missing possibly?

 

Thank You!

Matt

Hi,

This behaviour means there was a delay in PayPal sending the IPN sending the transaction details to your WHMCS installation. IPN stands for Instant Payment Notification so PayPal should be sending it instantly, before the client is returned to your install.

 

I suggest speaking with PayPal support so they can investigate why there was a delay in sending the IPN. In the meantime was have internal case MODULE-6076 open with the development team to research what changes can be made in the software to handle such delays in the IPN better.

Thank you for your reply!

 

This issue has occurred every time a customer makes a purchase through WHMCS, not just once or twice. They can make a purchase through the cart as a new customer, or they can login to the control panel and make an invoice payment and every time the result is the same. I also have a php script, that I created, that will receive PayPal IPN information and save it to a MySQL database and it has worked every time. I'm not trying to say you are incorrect about it being a PayPal issue, just wanted to make sure I gave you all available information on the issue. Thanks again!

Hello,

 

I just want to add some updated info, as I just tried a couple things with PayPal.

 

I went into PayPal and looked through the IPN log to see what had sent and the response. According to the log, the IPN's were sent and received with a 200 response from WHMCS. Also, I resent one of the IPN's and it never showed up in the transaction log. The callback URL was valid as well. What permissions does the client/modules/gateways/callback/paypal.php need? This is the only issue I could see that might prevent WHMCS from receiving the IPN info. Thanks!

Hi,

Please navigate to Billing > Gateway Log. Do you see any record of the payments? If so please copy the debug data and the result into your reply.

 

If there are no entries please double-check the IPN settings in your account are configured per our documentation @ http://docs.whmcs.com/PayPal

 

If that's configured correctly already, in your PayPal account navigate to History > IPN History and click the Message ID link corresponding to a transaction not recorded in WHMCS. Then copy the entire contents of the Message ID page into your reply here.

Hi John,

 

Out of many transactions, I have only 1 transaction showing in the Debug log. The result was "Invalid Receiver Email". The log is below:

The receiver email is my email address and it is valid, so not sure why it says invalid. The IPN log from PayPal is below:

If you need anything further, please let me know. I also have other transactions in the IPN History log that never showed up at all in the WHMCS gateway log, but the settings have been the same as above since I setup WHMCS. Thanks for all your assistance!
