Verisoul provides a React Native SDK that allows you to implement fraud prevention in your cross-platform mobile applications. This guide covers the installation, configuration, and usage of the Verisoul React Native SDK.

​
Installation

​
Using NPM

npm install verisoul-reactnative

​
Using Yarn

yarn add verisoul-reactnative

​
EXPO

The Verisoul SDK is not supported in Expo Go, so if you are using the managed workflow, you will need to use Expo’s custom development client. If you already have it set up, you can skip to step 3.

  1. Open the command line and navigate to your Expo project directory. Then, run the following command to install expo-dev-client.
npx expo install expo-dev-client
  1. Modify the scripts section in your package.json file to use expo-dev-client, it should look like this.
"scripts": {
  "start": "expo start --dev-client",
  "android": "expo run:android",
  "ios": "expo run:ios",
  ...
}
  1. Then install Verisoul SDK using npm or yarn
npm install verisoul-reactnative
yarn add verisoul-reactnative
  1. If an exception occurs during the build stating that the ai.verisoul:android package cannot be downloaded, add the following Maven repository inside your android/build.gradle file:
allprojects {
    repositories {
    // ...

     maven { url = uri("https://us-central1-maven.pkg.dev/verisoul/android") }

    }
 }

​
Usage

​
1. Initialization

import Verisoul, {
  MotionAction,
  VerisoulEnvironment,
} from '@verisoul_ai/react-native-verisoul';

useEffect(() => {
  Verisoul.configure({
    environment: VerisoulEnvironment.dev,
    projectId: 'PROJECT ID',
  });
}, []);

When this is called Verisoul library will be initialized, initial data together with session ID will be gathered and uploaded to Verisoul backend.

​
2. Get Session ID

Once the minimum amount of data is gathered the session ID becomes available. The session ID is needed in order to request a risk assessment from Verisoul’s API. Note that session IDs are short lived and will expire after 24 hours. The application can obtain session ID by providing the callback as shown below:

const sessionData = await Verisoul.getSessionID();

​
3. Provide Touch Events

Wrap your App With VerisoulTouchRootView

<VerisoulTouchRootView>
  // another Views
</VerisoulTouchRootView>

​
Android

​
1. Provide Touch Events (Android only)

In order to gather touch events and compare them to device accelerometer sensor data, the app will need to provide touch events to Verisoul. you need to Edit th MainActivity, to override dispatchTouchEvent function and pass the data to Verisoul like shown below.

import ai.verisoul.sdk.Verisoul
import android.view.MotionEvent


class MainActivity : ReactActivity() {

  override fun dispatchTouchEvent(event: MotionEvent?): Boolean {
    Verisoul.onTouchEvent(event)
    return super.dispatchTouchEvent(event)
  }

    // Other code...
}

​
iOS

​
Capabilities

To fully utilize VerisoulSDK, you must add the App Attest capability to your project. This capability allows the SDK to perform necessary checks and validations to ensure the integrity and security of your application.

Update your app’s entitlements file:

<key>com.apple.developer.devicecheck.appattest-environment</key>
<string>production/development (depending on your needs)</string>
