EMV 3D Secure

3D Secure is a pass-through operation for Cards Connect, which enables you to pass the data you receive after the 3D Secure verification.

These properties are all optional and can be found under the threeDSecureData object. Considering Cards Connect is not involved in the 3D Secure verification process directly, we don't have any logical validations for these properties and simply transmit them to the downstream systems to be validated by the scheme and the issuer.

• CAVV: Cardholder Authentication Verification Value is a cryptographic value created during the 3D Secure process. There are different types of cryptograms but the common one is a 28 character long Base64 encoded version that looks like this: DEpI+Yo8Vgm0qzDnJ1r3wbmJWlM=

• ECI: E-commerce indicator is a property that states the result of the 3D Secure process.

• version: 3D secure version. Cards Connect supports 3D Secure version 2 and expects a value like "2.2.0"

• directoryResponse: Response code received from the 3D Secure directory server.

• authenticationResponse: Authentication response code for the 3D Secure operation.

• directoryTransactionId: An identifier assigned to the 3D Secure transaction by the directory server. This is usually a GUID.

• xid: Unique identifier of the transaction.
