xs2a-react-native

Integrate XS2A from Tink Germany into your React Native App. This React Native SDK is a wrapper of xs2a-ios and xs2a-android.

Requirements

• iOS Version >= 13

Installation

npm install @fintecsystems/xs2a-react-native --save

iOS

cd ios/
pod install

Android

Make sure, that your app's minSdkVersion is 21 or higher and that your compileSdkVersion and targetSdkVersion is 33 or higher.

Because of that your gradle-build-tools-version has to be 4.2.0 or higher.

Make sure, because we raised the compileSdkVersion to 33, to delete the buildToolsVersion field.

android/build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "30.0.2" // Delete this line
        minSdkVersion = 21 // Upgrade if needed
        compileSdkVersion = 33 // Upgrade if needed
        targetSdkVersion = 33 // Upgrade if needed
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.2.2") // Upgrade if needed
...

Since Android 12 (API Level 31) you need to add android:exported to your AndroidManifest.xml.

android/app/src/main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.rn_testapp">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
        android:launchMode="singleTask"
        android:exported="true" <!--Add this line-->
        android:windowSoftInputMode="adjustResize">

Usage

import Xs2aReactNativeViewManager from "@fintecsystems/xs2a-react-native";

// ...

<Xs2aReactNativeViewManager
  style={{ width: '100%', height: '100%' }}
  wizardSessionKey="YOUR_WIZARD_SESSION_KEY"
  language="de | en | fr | it | es"
  onSuccess={({ nativeEvent: { credentials } }) => {
    // e.g. redirect to success screen

    // 'credentials' is only provided for XS2A.API sessions
    // with sync_mode = shared
    console.log('Success');
  }}
  onAbort={() => {
    // e.g. redirect to abort screen
    console.log('Abort');
  }}
  onNetworkError={() => {
    // e.g. redirect to error screen
    console.log('Network error');
  }}
  onBackButtonTapped={({ nativeEvent: { currentStep } }) => {
    // Called when the back button was tapped. Optional to implement.
    // currentStep can be any of "login", "tan", "account", "bank" or empty string ("")
  }}
  onSessionError={({ nativeEvent: { errorCode, recoverable } }) => {
    /**
    Session errors occur during a session.
    Implementation of the different cases below is optional.
    No action needs to be taken for them, in fact we recommend
    to let the user handle the completion of the session until one of the above .success or .failure cases is called.
    You can however use below cases for measuring purposes.
    NOTE: Should you decide to do navigation to different screens based on below cases, you should only do so
    in case of the recoverable parameter being false, otherwise the user can still finish the session.

Encryption Export Compliance Information

When uploading your app to App Store Connect, Apple typically wants to know some information on whether your app uses encryption and if it qualifies for an exemption under Category 5, Part 2 of the U.S. Export Administration Regulations. This SDK does qualify for such exemption, namely article (d):

Specially designed and limited for banking use or "money transactions"

Please note, that this only applies to this SDK and the corresponding XS2AiOSNetService, but not to any other parts of your app, which might not qualify for such exemptions and you might have to reconsider how to answer that dialog.
