ID Fraud Shield Disabled

This is Liveness Transaction Details API when ID Fraud Shield is disabled. In this configuration, the API returns the result generated by the VIDA Liveness detection engine without additional fraud analysis. ID Fraud Shield is not enabled in this setup, therefore the response will only include the liveness verification result. To retrieve the transaction details, partners must provide the transaction ID obtained from the Liveness API response or the SDK liveness output.

Liveness Fraud Ops Transaction Details

VIDA Liveness Fraud Ops is a near-real-time manual fraud review system for VIDA liveness service. When your system accepts a user's liveness check based on VIDA’s automated evaluation, Fraud Ops intercepts that session for deeper inspection — especially when the session score passes the AI threshold but may still exhibit signs of spoofing.

When VIDA detects potential fraud through its Fraud Ops, by a specially-trained human, you can receive the notification via webhook, or actively hit the Liveness Transaction Details API with added details.
