c# - Paypal payment status, how to get status of that payment again -

what if status pending payment @ ipn listener address i.e example.com/ipn.aspx , how can automate when paypal reviews payment , cancel/complete can process order accordingly.

do paypal sends transaction details @ ipn 1 time again after reviewing? , there way test these things in sandbox?

sorry many questions i'm trying 2 days now, have used gettransactiondetails in sandbox, working correctly when go live giving permission denied error.

this error occurs when api caller of gettransactiondetails not 1 has initiated original transaction. owner of original transaction id has give permission api caller making gettransactiondetails api call.the owner of transaction id set permissions here
