Transaction Details

Enter the payer authentication transaction ID into the quick search feature to find all segments of a transaction. For a transaction in which the card is not enrolled, find payer authentication data in the Transaction Details window in these sections:

Request Information section: The service appears in green. You can obtain additional information about related orders by clicking the link on the right.

Order Information section:

For Mastercard, the ECI value is 00: authentication is not required because the customer’s Mastercard card is not enrolled. Other cards have an ECI value of 07.

The AAV/CAVV area is empty because you receive a value only when the customer is authenticated.

The XID area is empty because the card is not enrolled.
