3DS2 API

API v3
Last updated May 2021

Verify your customer's identity simply and seamlessly to minimize fraud. Use our strong customer authentication to benefit from liability shift.

API version 3: 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.
