'IPN validation failed' – Transaction stuck in 'resending' status (in paypal)

[jaytech880]

Hello

How do i solve the following issue

all orders on the site are coming in, all is working fine and orders are recorded in the eStore.

One order however, was Unsuccessful to record in eStore due to ‘IPN validation failed’ / ‘cURL error 28’ (per ipn_handle_debug).

usually, in such cases, i would login to paypal and resend the notification (@IPN history) and all becomes fine. in minutes, the order would show up in eStore.

This time however, after re-sending, the ‘IPN Delivery status’ in paypal remains ‘Sent – resending’ (since last Friday=4 days). and eStore has yet to accept the order.

After contacting PayPal, they said i cannot resend again while in ‘resending status’ and they said the following

“The IPN will remain in resending status until your listener acknowledges receiving the IPN and we receive an HTTP 200 response.”

Problem Conclusion

How do i import this order to estore without the ability to resend via paypal?

Go to the “Add/Edit Customers” interface from the eStore’s admin menu. Then add the details in there and save it.

this will not work for me

i know that i can do that. but i need it to come via IPN system as i am relying on to many other items within the workflow. such as Affiliate tracking (can also be done manual but not the Custom Values) reporting to analytics, and more.

therefore i’d rather fix it rather then ignoring. if posible

Question: Is this problem related ONLY to a particular transaction, product, or customer? In other words, is this a “one off” problem, or is there a pattern to this, beyond that 1 particular transaction?

I will have to do complete cross checking to know for sure. I only noticed last week that IPN’s can be missed.

ps. for future plugin updates, there would be a great value to add option for ‘failed ipn email alerts’. it will serve as a signal to the store owner to check if any orders are missing.

Generally, you don’t miss the IPN (unless something was going on the server at that very time and the server rejected the IPN). Our plugin does the same thing for all IPNs and we know that functionality is working fine. The first response it gives to paypal after receiving an IPN is the 200 response code.

I don’t know what I can do from my end for this specific IPN issue you have. The plugin does send an email to the admin if the validation of an IPN fails. I wouldn’t mind adding another email option for the scenario you mentioned but it is kind of an unique situation that is happening on your server only.
