# Agents by stage

> Configure liveness check, document validation, and facematch as independent components.

Use this path when you only need to implement part of the verification process or when you want to control each stage separately.

## Liveness check

<CardGroup cols={1}>
  <Card title="Liveness check (Flows)" icon="camera" href="/en/guides/integraciones/identidad/flows-liveness-agent">
    Photo capture on WhatsApp Flows screens with liveness evaluation.
  </Card>
</CardGroup>

## Document validation

<CardGroup cols={1}>
  <Card title="Document check (Flows)" icon="id-card" href="/en/guides/integraciones/identidad/document-check-flows">
    Document capture in Flows with control over image sources.
  </Card>
</CardGroup>

## Facial comparison

<CardGroup cols={1}>
  <Card title="Facematch" icon="user-check" href="/en/guides/integraciones/identidad/facematch-agent">
    1:1 validation between selfie and face extracted from the document.
  </Card>
</CardGroup>

<Tip>
  If you later want to unify stages, migrate to [Full verification](/en/guides/integraciones/identidad/full-verification).
