Paypal payment status, how to get status of that payment again

Question

What if i get status pending for a payment at my ipn listener address ie example.com/ipn.aspx and how i can automate it so when Paypal reviews the payment and cancel/complete it so that i can process the order accordingly.

Do Paypal sends transaction details at ipn again after reviewing? And is there is a way to test these things in sandbox?

Sorry too many questions but i'm trying for 2 days now, i have used GetTransactionDetails in sandbox, it was working correctly but when i go live its giving permission denied error.

Answer 1

This error usually occurs when the API caller of GetTransactionDetails is not the one who has initiated the original transaction. The owner of the original transaction id has to give permission to the API caller who is making the GetTransactionDetails API call.The owner of the transaction id could set permissions here
