This guide will help you set up and run the React Native Face Match & ID Check Sample App, which demonstrates how to integrate Verisoul into a React Native application.

## About the Sample App

The [React Native Face Match & ID Check Sample App](https://github.com/verisoul/react-native-facematch-sample-app) is a demonstration project that showcases a working Verisoul integration in a React Native environment.

## Prerequisites

Before you begin, you'll need:

* Node.js and npm installed on your system
* Git for cloning the repository
* A Verisoul API Key (obtain this by [scheduling a call](https://meetings.hubspot.com/henry-legard))

## Installation Steps

### 1. Clone the Repository

```bash theme={null}
git clone https://github.com/verisoul/react-native-facematch-sample-app.git
cd react-native-facematch-sample-app
```

### 2. Configure API Key

Make sure to use the correct API key for the environment you are using:

```javascript theme={null}
let headers = {
    "x-api-key": "YOUR_API_KEY_HERE",
    "Content-Type": "application/json"
}
```

### 3. Install Dependencies

Install all required npm packages:

```bash theme={null}
npm install
```

### 4. Run the Application

Start the app via Expo either on a simulator or a physical device:

```bash theme={null}
npx expo start
```

## ID Check Integration

To run the sample app with ID Check functionality, simply add the `?id=true` parameter to the get session URL:

```javascript theme={null}
const faceAndIdSession = await fetch(`https://${API_URL}/liveness/session?id=true`, {
    method: 'GET',
    headers: headers,
})
```

## What to Expect

Once running, you'll see a demonstration of how Verisoul's Face Match and ID Check work in a React Native environment.

## Next Steps

After exploring the sample app, you can use it as a reference for implementing Verisoul in your own React Native applications.
