Implement frictionless flow

Overview

The 3DS frictionless flow authenticates the end user without a challenge when the transaction is assessed as low risk based on your configured risk rules. This preserves a seamless checkout while remaining compliant with EMV 3‑D Secure (3DS).

To enable frictionless outcomes, configure your thresholds and conditions in Configure rulesets for 3DS decisioning.
