note

The sample request and response on this page assume that the acctNumber supported 3DS 2.1 authentication, but the issuer needed additional information from the cardholder to authenticate the transaction i.e. a challenge flow. After the cardholder provided additional information to the issuer, it authenticates the transaction i.e. transStatus = Y.

If transStatus = N, the response will also have the transStatusReason field.
