My problem is how i correlated this user to this subscription request. Is there is any option such that i can send my user's identity on paypal so that i can fetch information from paypal regarding this user. Or any paykey so that we got information about this transection.
Solution
You can pass your user ID for tracking users as the "item_number" or "custom" value. Both would be returned to in an IPN post and through PDT.
If you wanted to query PayPal about it you can do a GetTransactionDetails API call to look up a transaction ID and get the buyer information returned as well as the payment status.
