If the payment was 3DS-authenticated by us, our Disputes team will proceed with re-presentment or dealing with pre-arbitration, using our internal authentication log as reference.
If the payment was 3DS-authenticated by a third party, which we do not recommend, you will need to provide us with the authentication log.
