# Entrust Identity Verification Documentation

> Entrust Identity Verification is a comprehensive API and SDK platform for identity document verification, biometric checks, watchlist screening, and fraud detection. Customers integrate via REST API (v3.6 current) and native SDKs (Web, iOS, Android, React Native, Flutter), orchestrating verification flows through Workflow Studio.

Authentication uses token-based Bearer auth. All API paths are versioned (e.g. `/v3.6/...`). Regions: EU (`api.eu.onfido.com`), US (`api.us.onfido.com`), CA (`api.ca.onfido.com`).

The typical integration flow: create an applicant → create a workflow run (returns an SDK token) → collect captures via SDK → retrieve results via webhook or polling.
