I've been trying to integrate my website with the PayPal IPN, but I've been unsuccessful so far. The Paypal documentation HERE: SSL Certificate Upgrade Microsite entails some specifications that need be met. My server supports SHA-256 and uses VeriSign G2 Root Certificate as well. I've installed SSL on this domain too, but still I get nothing with the Paypal IPN.
I have a file IPNSampleCode.php at (NOT MY REAL WEBSITE) https://XYXYXYX.com/IPN/IPNSampleCode.php which is supposed to be called by the Instant Payment Notification (IPN) Simulator, but I keep getting 'IPN was not sent, and the handshake was not verified. Please review your information.
' whenever I run the IPN simulator against the IPN handler URL 'https://XYXYXYX.com/IPN/IPNSampleCode.php'
What could I be missing, or what might I be doing wrong?
Thank you for contacting PayPal Merchant Technical Services, I apologize for the delay in responding to your email.
We are aware of this issue with our IPN Simulator and our development team is working on a fix. Until this issue is fixed, I'd suggest running your IPN tests by making payments in Sandbox as we do send IPN requests with every payment.
If you have a similar issue with your payment tests, please let us know and we can take a look.
My apologies for the inconvenience caused.
