I ve looked through the documentation, I ve tried downloading various example code, and I ve tried hacking various permutations. After a full day s worth of work, I m spent, and throwing in the towel. So now I m begging for some help. Can someone please post a PHP class or function, wherein I can simply verify that the ping to my IPN script is legitimate, using signature version 2?
Thank you so much.
Zack
