I'm using the code CURL example: https://developer.paypal.com/docs/classic/ipn/ht-ipn/ If I use the tool IPN Simulator (web accept) https://developer.paypal.com/developer/webhooksSimulator/ I get $res == "VERIFIED" in Sandbox and Production I get $res == "INVALID" If I do file_put_contents('testpost.txt', file_get_contents('php://input')); I do see a POST of the payment confirmation in son formate even with curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); i get $res == "INVALID" How do I go about debugging this?
