React Native

Footprint provides an integration using React Native. The usage is similar to what we have on the web, but instead of using iframes, we use an in-app browser (webview).

1. Install footprint-react-native:

bash
# With NPM
npm install @onefootprint/footprint-react-native

# With yarn
yarn add @onefootprint/footprint-react-native

2. On iOS, make sure to have the native dependencies installed:

bash
cd ios
pod install

1. Grab the Onboarding Publishable Key, for example ob_test_VMooXd04EUlnu3AvMYKjMW.

2. Import the styles file and embed the Footprint button, passing the Publishable Key and the callback functions:

typescript
import { FootprintButton } from '@onefooprint/footprint-react-native';

import { View } from 'react-native';

const Screen = () => {
  const handleCompleted = (validationToken: string) => {
    console.log(validationToken);
  };

  const handleCanceled = () => {
    console.log('user canceled');
  };

  return (
    <View>
      <FootprintButton
        publicKey="ob_test_VMooXd04EUlnu3AvMYKjMW"
        onCompleted={handleCompleted}
        onCanceled={handleCanceled}
      />
    </View>
  );
};

1. Alternatively, you can open Footprint from a custom button:

typescript
import footprint from '@onefooprint/footprint-react-native';

import { View, Button } from 'react-native';

const Screen = () => {
  const handlePress = () => {
    footprint.open({
      publicKey: 'ob_test_VMooXd04EUlnu3AvMYKjMW',
      onCanceled: () => {
        console.log('user canceled');
      },
      onCompleted: (validationToken: string) => {
        console.log(validationToken);
      },
    });
  };

  return (
    <View>
      <Button title="Verify identity" onPress={handlePress} />
    </View>
  );
};
