Xendit Fingerprint SDK React Native

React Native SDK for device identification and fingerprinting with Xendit services.

Supports Android and iOS React Native mobile applications.

Basic Usage

Initialize the SDK with your public API key on application start up and perform a scan.

The SDK must be initialized before use.

// App.js
import React from 'react';
import { SafeAreaView } from 'react-native';
import FingerprintSdk from 'xendit-fingerprint-rn';

const App = () => {
  React.useEffect(() => {
    // Initialize the SDK on every application start up
    FingerprintSdk.init('MY_PUBLIC_API_KEY').then((sessionID) => {
      // Run a scan after completing initialization
      FingerprintSdk.scan();
    });
  });

  return <SafeAreaView>{appContents}</SafeAreaView>;
};

export default App;

Session ID is retrievable from either FingerprintSdk.init() on SDK initialization or from the FingerprintSdk.getSessionId() convenience method.

Both of these functions returns a Promise that resolves to a Session ID of type string

// On SDK init
const sessionID = await FingerprintSdk.init('MY_PUBLIC_API_KEY');

// After SDK init
const sessionID = await FingerprintSdk.getSessionId();

This Session ID can then be passed on to other Xendit APIs that support device fingerprinting. Please refer to the respective API's documentation for further info.

Requirements

  • React native (0.60 or newer recommended for autolinking)
  • Android 5.0 (API 21) or newer
  • iOS 11.0 or newer

Installation

With Yarn:

$ yarn add xendit-fingerprint-sdk-rn

Install the package with NPM:

$ npm install --save xendit-fingerprint-sdk-rn

Linking the library:

note for React Native 0.60 and above, autolinking is available and this step should be skipped.

$ npx react-native link xendit-fingerprint-sdk-rn

iOS Setup

Frameworks must be enabled in CocoaPods by adding use_frameworks! into your Podfile.

target 'MyProject' do
  use_frameworks!
  # ...etc
end

Enable the BUILD_LIBRARY_FOR_DISTRIBUTION setting for every Cocoapod target using a post_install block in your iOS Podfile. Either by including this snippet into an existing post_install block or creating a new block at the bottom of your Podfile.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
    end
  end
end

Run pod install in your iOS directory containing the Podfile.

$ (cd ios; pod install)

Android Setup

Ensure that mavenCentral is included as a repository in build.gradle.

For example:

allprojects {
    repositories {
        mavenCentral()
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        google()
        maven { url 'https://www.jitpack.io' }
    }
}

Methods

All SDK methods are asynchronous, returning a Promise object. Refer to the returns section of each method for the resolved type.

init()

The SDK must be initialized before it can be used.

  • Initialization must be ran on every application start up.
  • The SDK will associate a session ID for the running app until it's killed.
  • A new session ID will be assigned on every application start up .
const sessionId = await FingerprintSdk.init(publicKey);

Parameters

Name Type Required Description
publicKey string Yes A valid public API key provided by Xendit Dashboard

Do not use your private API key!

Returns

Name Type Description
sessionId string Generated session ID

scan()

Scans the device mobile device and sends the device fingerprint data to Xendit.

  • Scan should be called immediately after initializing the SDK.
  • Scan can be called multiple times within a session.
  • Do not await the scan, let it run in the background. This avoids blocking any foreground application code execution.
FingerprintSdk.scan();
// Or
FingerprintSdk.scan(customerEventName, customerEventID);

Parameters

Name Type Required Description
customerEventName string No Optional event name to associate with this scan. Recommended to use snake case formatting. e.g. 'some_event_name'
customerEventID string No Optional identifier associated with the event. e.g. user account ID

getSessionId()

Convenience method to retrieve Session ID after SDK initialization.

const sessionId = await FingerprintSdk.getSessionId();

Returns

Name Type Description
sessionId string Generated session ID

setEnabled()

Enables or disables the SDK.

  • When disabled, the scan method will do nothing. No data will be sent to Xendit.
  • When enabled, the SDK will resume operating as normal.
  • await should be used to ensure the SDK is completely enabled/disabled.
await FingerprintSdk.setEnabled(enable);

Parameters

Name Type Required Description
enable boolean Yes true enables the SDK.
false disables the SDK.

Returns

Name Type Description
void Resolves once SDK is enabled/disabled fully.
