I get this error every single time I want to try and test the IPN simulation.
The listener code I have is very simple:
<?php
file_put_contents('export.txt', var_export($_POST,true));
?>
I have this uploaded on my servers, which have valid and certified SSL.
I type in the URL to the listener, and choose express checkout.
I click 'Send IPN' I get the non-informative error 'IPN was not sent, and the handshake was not verified. Please review your information.'
We thought it was the SSL so we bought and reinstalled (twice now) certificates. SSL is not the problem. Everything comes back green when we run SSL certificate checks on the URL.
On top of all of this, the example code on https://developer.paypal.com/docs/classic/ipn/gs_IPN/
contains .PHP code that once we put into a file, and ran the simulator, it got stuck in a endless loop that is currently filling our server's error log with a constantly growing error log.
Anyways, the endless loop is not the main problem here. The IPN simulator refuses to work under any condition, we've tried everything the internet had to offer, from answers to Stack Overflow or simply calling PayPal support to be told we need to email someone because they had no clue what we were talking about and then the phone call disconnected.
I have also tried the sample code found here: https://developer.paypal.com/docs/classic/ipn/ht_ipn/
Why are there two separate PHP sample code guides? Anyways, it did not work either.
We are trying to set up a process to be a business through PayPal, but this is making it impossible.
Is there any help for this other than the error message that doesn't tell me what's wrong at all? Is there an error log somewhere I'm missing?
