Adyen is no longer developing the Classic API integration<\/strong><\/p>\n

This page is for the Classic API (\/authorise<\/code>) integration, which we no longer accept new integrations with. <\/p>\n

We strongly recommend migrating to the newer data-only integration on Checkout API<\/a> integration. To use this newer integration, you must also migrate to the Checkout API<\/a>.<\/p>\n<\/div><\/div>\n

In a regular 3D Secure 2 flow, the payment has to be authenticated by the issuer before it can be authorised. In a data-only flow, you send the same 3D Secure 2 data but the schemes directly handle the authentication request. The data-only request goes directly to the scheme, and then the scheme includes their own risk data in the authorisation message before sending it to the issuer.<\/p>\n

\n

Data-only is currently only available for Mastercard. Before using the data-only flow, make sure to check the regulations that apply to your country or region. Using the data-only flow in countries\/regions where SCA is mandated (for example, within the EEA) can lead to an increased amount of authentication rejections.<\/p>\n<\/div><\/div>\n

Using the data-only flow<\/h2>\n

The data-only flow allows you to use the scheme's 3D Secure-specific risk scoring models, which helps increase your authorisation rates in specific markets, without incurring additional fees.<\/p>\n

You can also use the data-only flow when you integrate with Adyen as a standalone 3D Secure 2 provider with an authentication-only implementation<\/a>.<\/p>\n

Because there is no authentication request sent to the issuer in a data-only flow, your shoppers will not be presented with a 3D Secure 2 challenge.<\/p>\n

\n

Because no strong customer authentication is applied to a data-only transaction, the chargeback liability stays with you and does not shift to the issuer.<\/p>\n<\/div><\/div>\n
