Implementation Overview

Notify your account representative that you want to implement payer authentication (3-D Secure). Give them the merchant ID that you will use for testing. For more information, see Required Merchant Information.

Implementation tasks include:

Download, import, and configure the Cardinal Mobile SDK for either iOS or Android.

For each purchase request:

Build the authentication request.

Invoke the authentication.

Handle declines.

Make another back-end, server-to-server call to request the following services:

: Payer Authentication Validation

: Card Authorization service (optional)

Use the test cases to test your preliminary code and make appropriate changes. See Testing Payer Authentication.

Ensure that your account is configured for production.
