I don't have a bank account so I don't have verified bank account and couldn't test my IPN in paypal. What I did is used a 3rd party IPN Testing Enviroment from eliteweaver.co.uk. I modified the cfhttp to <CFHTTP URL="http://www.eliteweaver.co.uk/testing/ipntest.php?#str#" METHOD="GET"></CFHTTP> I tested it and the result was: IPN Creation Date: 23:34:39 Apr 02, 2003 PDT IPN Expiration Date: 08:34:39 Apr 04, 2003 PDT Send Count: 1 Target IPN Script: http://203.131.66.234/Singleton/IPN.cfm IPN Sent: 23:34:39 Apr 02, 2003 PDT HTTP Status: HTTP/1.1 200 OK IPN Received: 23:34:40 Apr 02, 2003 PDT Post Back: 1 second Variables Sent: 53 Variables Expected: 54 Variables Received: 0 String Length Sent: 1225 String Length Expected: 1246 String Length Received: -1 Desired Response: VERIFIED Actual Response: INVALID Intentional Response: No!
