Onboarding

What this use case solves

Identity verification with document capture and reuse addresses the challenge of verifying identity with the broadest set of risk signals while also capturing a government-issued document, all in a single process.

Use this use case when:

• You need biometric identity verification combined with behavioral alerts and document capture.

Do not use this use case when:

• You do not need document capture → look at the other onboarding use cases.

Capabilities involved

Pipeline executed within a single process:

LivenessIdentity VerificationRisk Fraud ClassificationDocument Capture & Reuse

Capability	Required	Role in the flow
Liveness	Optional for API; required for Web and Native	Confirms that a real person is in front of the camera at capture time. Biometric anchor of the process.
Identity Verification	Required in all cases	Verifies whether the transaction face belongs to the holder of the provided government identifier, using Unico's identity base and additional signals.
Risk Fraud Classification	Required in all cases	Cross-references behavioral signals to flag fraud risk associated with the document identifier.
Document Capture & Reuse	Required in all cases	Captures a new document image or returns a previously captured image associated with the user.

Prerequisites

• Bearer token — see Authentication.
• Sandbox credentials — see Environments.
• SDK or Web component installed — only for Web and SDK integrations. See SDKs and Tools.

Step-by-step implementation

Native

Integration via native SDK — capture runs inside your app using the Unico SDK for Android, iOS or Flutter.

1. Install the SDK — add the Unico SDK dependency for your platform. See the setup guide for Android, iOS or Flutter.
2. Create a process — call Create Process with the appropriate flow value and the user's identifier. Use the returned token to initialize the SDK.
3. Start the capture — the SDK renders the camera UI and performs liveness detection on-device, returning the captured payload.
4. Query the result — call Get Process to retrieve the capability results.
5. Apply business rules — evaluate the response fields to approve, deny or escalate.

Web

Integration via iFrame, Redirect or Native — Unico hosts the capture UI, and you receive the result via polling.

1. Create a process — call Create Process with the appropriate flow value and the user's identifier. The response includes a userRedirectUrl.
2. Redirect the user — send the user to userRedirectUrl. Unico renders the capture journey. Or webAppToken in native apps.
3. User completes the journey — after capture, the user is redirected back to your callbackUri.
4. Query the result — call Get Process to retrieve the capability results.
5. Apply business rules — evaluate the response fields to approve, deny or escalate.

Web

Quick integration via browser, no installation needed.

API

Direct API integration — capture the selfie using the Unico SDK or your own UI following the Capture Standard, then send the image directly to the Unico API.

1. Capture the selfie — use the Unico SDK for your platform, or build your own UI following the Capture Standard, to obtain a selfie image that meets liveness requirements.
2. Create a process — call Create Process with the user's identifier and the selfie as imagebase64.
3. Query the result — call Get Process to retrieve the capability results.
4. Apply business rules — evaluate the response fields to approve, deny or escalate.

API

Full control over the flow with back-to-back integration.
