Hi the new PayPal Buttons are great and working just fine. but when I have implemented them, I noticed that I cannot match the returned capture details with my records , unless I use sessions, which I am reluctant to use for so many reasons I can't describe here. How can I add to the posted button parameters my own reference that I get back from PayPal in the capture details. then I can easily match the ref with my records and allow payment to go through my system. usually the reference is some sort of hashed token. if you have a way to do this that I may have over looked then please do tell me. Regards and keep up the great work.
