Understanding Payer Authentication Information

The Payer Authentication Information section on the Details page contains details of the payer authentication request for the selected transaction. The following table describes each of the fields that display.

Request Information	Description
AAV/CAVV	Unique identifier generated by the customer's issuing bank after the customer is authenticated.
Account Identifier	Masked string used by the ACS.
Acquirer BIN	(Bank Identification Number) First six digits of acquiring bank.
ACS URL	Access Control Server URL of the issuing bank where the customer is redirected during authentication.
Card Enrollment Result	Result of the service request: Y = Card enrolled N = Card not enrolled U = Cannot authenticate
Card Expiration Date	Expiration month and year (mmyy) of the card used in the transaction.
Data Server Password	Merchant’s masked authentication password to the ACS. Applies only to cards issued outside the U.S.
Date	Date and time of request. Although the date and time should appear sequentially during all stages of the processing of an order, they may not because of differing time zones and synchronization between servers.
Directory Server URL	URL for the server of the payment card company.
Electronic Commerce Indicator (ECI)	Authentication result required by your payment processor if you are not using `Cybersource` for payment services.
Merchant Country	Your country of operation.
Merchant ID	Contains one of two values: In the Request Information, you see your `Cybersource` merchant ID. In the rest of the transaction details, you see the login ID for the ACS URL.
Merchant Name	Your company’s name.
Merchant URL	Your company’s website.
Primary Account Number (PAN)	Your customer’s masked account number.
Purchase Amount	Amount and currency of the transaction.
Request ID	Unique identifier assigned in each request and returned in each response.
Transaction Status	Indicates the authentication status of the transaction: Y = Authentication successful. All data needed for clearing, including the Cardholder Authentication Verification Value (CAVV), is included in the message. A = Attempts processing performed. Authentication not completed, but a proof of authentication attempt (AAV/CAVV) was generated. U = Authentication cannot be performed because of a problem. N = Authentication failed. Customer failed or canceled authentication. Transaction denied.
Transaction Type	Service requested.
Unique Transaction Identifier (XID)	Unique transaction identifier generated for each Payment Authentication Request (PAReq) message. The Payment Authentication Response (PARes) sent back by the issuing bank contains the XID of the PAReq. To ensure that both XIDs are the same, store the XID from the request so that you can later compare it to the XID in the response. To find all requests related to a transaction, you can also search transactions for a specific XID.
