Is it possible to retrieve refund details such as the parent transaction ID with the PayPal NVP API? So far I know it's possible to retrieve the details of a "Received" transaction by using "GetTransactionDetails" but for refunds it seems that method doesn't work.
body = {
USER: user_id,
PWD: password,
SIGNATURE: signature,
METHOD: 'GetTransactionDetails',
TRANSACTIONID: refund_id
VERSION: 204
}
response = HTTParty.post('https://api-3t.sandbox.paypal.com/nvp', body: body).
#Parsed response:

}
I've tested it again with another refund ID and I think my example from above failed as refunds for PayPal fees cannot be retrieved. Regular refunds can be retrieved with the GetTransactionDetails.
