In order to request complete details about a transaction, eWAY's Transaction Query API can be used. This will return details any details about the customer (including any entered in the Responsive Shared Page) along with information about the transaction and any fraud rules that were triggered.
The Transaction Query API is a very simple request with either the Transaction ID or the Access Code for the transaction.
