Ipn script

PHP

  1. The last time I wrote a paypal ipn was 2009. Since then is there any change on paylal ipn or on paypal form I should apply the changes?
  2. GoogleCheckout and ClickBank are still active and widely used?

I seem to remember having to make one or two minor changes to my Paypal IPN scripts over the years in order for them to continue working. I can’t remember specifically what needed to be changed though, all I can remember is that it was very minor and that the scripts are almost the same as they were ten years ago when I forst wrote them.

May I ask to share your ipn script with me that I can detect changes?
