Implementing Cardinal Cruise Direct Connection API Payer Authentication

The Cardinal Cruise Direct Connection API supports 3D Secure 2.x and is backward-compatible with 3D Secure 1.0 when the issuer, acquirer, or both, are not ready for 2.x. This integration allows you to use an iframe to complete the device profiling and 3D Secure authentication requirements without including third-party JavaScript directly on your site.

The implementation still requires the use of JavaScript on the page, and it uses CardinalCommerce JavaScript to leverage the authentication. However, the CardinalCommerce JavaScript is hosted and contained in the iframe and does not directly access your webpage.
