## Predictive Document Verification (DocV)
Predictive Document Verification (DocV) captures and verifies government-issued identity documents — such as driver's licenses and passports — through a native SDK with a built-in camera UI. Your application embeds the SDK, which guides the consumer through document capture and image upload. Socure then verifies the document and returns results to your backend via webhook.

| iOS | [5.4.2](https://github.com/socure-inc/socure-docv-sdk-ios) | June 15, 2026 |
| Android | [5.4.8](https://github.com/socure-inc/socure-docv-sdk-android) | June 17, 2026 |
| React Native | [5.2.8](https://github.com/socure-inc/socure-docv-demo-app-react-native) | June 30, 2026 |

\*The Web SDK uses hosted JavaScript and is continuously updated. You automatically receive the latest version without requiring manual upgrades.

## How it works
Get started with the Predictive DocV SDKs by completing the following steps:

1. ### Build a Capture App flow
Create your [custom Capture App flow](https://help.socure.com/riskos/docs/capture-app#/) in RiskOS™ using a Use Case Flow template.

2. ### Integrate with the DocV SDK
Follow the **SDK Quick Start Guides** to integrate the DocV SDK into your application.

3. ### Generate a transaction token
In your backend, call the [/api/evaluation](https://help.socure.com/riskos/reference/postevaluation#/) endpoint to generate a DocV transaction token (`docvTransactionToken`).

4. ### Render the Capture App
Use the `docvTransactionToken` and your SDK key to initialize the SDK and render the Capture App interface in your application.

5. ### Receive the verification results
When the document capture and upload process is complete, your app receives a success callback. Your webhook integration can then receive the DocV results in the payload of the `evaluation_completed` event.
