3D Secure Parse PaRes

After a successful authentication with a 3D Secure call, this call allows to parse the PaRes field to retrieve the ECI, XID, CAVV and CAVVAlgorithm fields to be sent to the Sale function.

Note: The use of this method is discouraged and will be removed/restricted in future deployment. The PaRes parameter of Sale/Authorize calls must be used instead.

Code samples

Note: Gateway API transactions are done with a different library than payment-page API. See the code sample comments for more info:

    *   Transaction name is '3DSParse', once you create a new transaction passing this as parameter, 
    *   you need to set the mandatory data using the follow methods:
    *    setPaRes()

The body of the response is in JSON format.

The following fields are present in the response :

Name Type Description
errorCode String See API Response Codes
errorMessage String See API Response Codes
ECI String Electronic Commerce Indicator
XID String Xid Transaction ID generated by the 3D Secure service that uniquely identifies a 3D Secure check request
CAVV String Cavv Cardholder Authentication Verification Value
CAVVAlgorithm String CAVVAlgorithm returned from 3D secure authentication
