3DS2 SDK - Android & iOS

API v3
Last updated January 2024

Use our native android SDK to improve issuer challenge display for 3DS2 and increase the chance of a frictionless authentication using mobile device data.

API version 3 required: New merchants boarded from May 2021 will have v3 of the API enabled against their account (enabling new test values with iOS/Android support on Try). Existing merchants will be gradually migrated - contact support to accelerate this if you require v3 for testing.

The Access 3DS API is periodically tested against the latest version of the Cardinal SDK. You can see the latest tested version in thechange log.

We strongly recommend signing uphereso you are kept informed of SDK updates.


Visualize our 3DS API and see the flow of a 3DS authentication.
