What this product solves
Allows proving that the user meets the minimum required age in a 100% biometric way, without document friction. Suitable for flows where facial age estimation is already sufficient for the decision — such as access to adult content, sports betting or alcoholic beverages in digital environments.
Use this product when:
- Regulation or internal policy does not require documentary evidence of age.
- The priority is to minimize friction in the user journey.
- The usage context accepts biometric estimation as sufficient proof (e.g., streaming platforms, betting, adult content).
- Transaction volume is high and document capture would represent an operational bottleneck.
Do not use this product when:
- Regulation requires documentary proof of age.
- The service involves high regulatory or financial risk (e.g., credit, healthcare).
- The target audience's age range makes facial estimation less reliable (e.g., teenagers close to the legal age).
Capabilities involved
Pipeline executed within a single process:
| 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 for idage; not used in idagedocumentless | Verifies whether the transaction face belongs to the holder of the provided government identifier, using Unico's identity base and additional signals. |
| Age Verification | Required | Estimates the age range from facial biometrics. The result determines whether the user meets the minimum required age. |
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
- Web
- API
Integration via native SDK — capture runs inside your app using the Unico SDK for Android, iOS or Flutter.
- Install the SDK — add the Unico SDK dependency for your platform. See the setup guide for Android, iOS or Flutter.
- Create a process — call Create Process with the appropriate
flowvalue and the user's identifier. The response includes thewebAppToken. - Open the journey — open the SDK with the
webAppToken. The SDK runs the journey in your app and callsonSuccesswith theprocessIdwhen the user finishes. - Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
Integration in the browser — Unico hosts the journey, and you open it with the Journeys SDK or by redirecting the user.
- Create a process — call Create Process with the appropriate
flowvalue and the user's identifier. The response includes the processid, thetokenand theuserRedirectUrl. - Open the journey — open it inside your page with the Journeys SDK, passing the process
id(astransactionId) and thetoken. This is the recommended option. If the journey can run outside your page, use Direct access instead: send the user touserRedirectUrl, and setcallbackUriin Create Process so Unico knows where to send them back. - User completes the journey — the Journeys SDK calls
onFinish. With Direct access, Unico sends the user back to yourcallbackUri. - Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
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.
- 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.
- Create a process — call Create Process with the user's identifier and the selfie as
imagebase64; the executed capabilities are defined by your API Key configuration. - Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
What's next
- Test in Sandbox first — use sandbox credentials to validate the full flow before going live. See Environments.
- Set up webhooks — receive result notifications asynchronously instead of polling. See Webhooks and Events.
