I am creating a website on which i have to include paypal.
I want to know how i can get a unique key, about which user had made me payment.
How can i recognize which person paid me through paypal.
I can pass any value (his mail id, name, phone number or a unique key) but i don't know how paypal will return that value to me...
Please anybody help me.
Thanx in advance...
