React Native Push Notifications

How to set up WonderPush push notifications on React Native cross-platform apps

Install push notifications in React Native apps in 4 steps.

Setting up push notifications for your React Native app is easy. Push notifications are the ideal solution to re-engage users and bring them back to your app.

Estimated setup time: 15 minutes.


You'll need:

  • NodeJS, v8.3 or ulterior
  • React Native
    react-native >= 0.60.0
  • For Android:
    • A device or emulator with Google Play services installed and up-to-date.
    • A Firebase account.
    • Android Studio.
  • For iOS:
    • XCode
    • An iOS device such as an iPhone or an iPad
    • An iOS Push Certificate (here's a how to obtain it)


Upgrading from our SDK version 1.x?

Follow this guide to update your integration.


Expo users

If you're using expo, you'll need to "eject" your app. Simply go into your project's folder and run:

expo eject

Step 1. Create your project

Click on New Project:

Choose a name for your project and select Android and iOS as platforms then click Create:


Already have a project?

Just add the Android or iOS platforms to any existing project by going to Settings, selecting the first tab named after your project and clicking Edit. You'll be presented a form that lets you add a platform.

Step 2. Setup your push credentials

Android - Add your Firebase credentials

  1. Locate your Server Key and Sender ID in the Firebase project Cloud Messaging settings.
<br>In your Firebase project console, click the *gear icon* (⚙️) and select *Project settings* and go to the *Cloud Messaging* tab.<br>In your Firebase project console, click the *gear icon* (⚙️) and select *Project settings* and go to the *Cloud Messaging* tab.

In your Firebase project console, click the gear icon (⚙️) and select Project settings and go to the Cloud Messaging tab.

  1. Go to your WonderPush dashboard, in the Settings page, select the Platforms tab and click on Android application.
  1. Paste the Server key.
  2. Click Save.

iOS - Upload your push certificate

Head to the Apple developer website, go to Accounts, then Certificates, Identifiers & Profiles and click the plus button to add a new certificate. Choose the type Apple Push Notification service SSL (Sandbox & Production):

Then select your app ID (be sure not to select the app ID for the notification service extension):

Follow the rest of the wizard to obtain your certificate.

Go to Settings / Platforms, click the iOS application section title and fill in:

  • your push certificate by clicking the Browse button,
  • the push certificate password if appropriate.


Be sure to check how to use WonderPush in both Sandbox & Production.

Step 3. Add the SDK

Create your React Native application if you haven't already, see the official React Native guide and click React Native CLI Quickstart, for more details.

Add the WonderPush React Native SDK:

npm install react-native-wonderpush --save
npm install react-native-wonderpush-fcm  --save

Link the WonderPush React Native SDK:

react-native link react-native-wonderpush
react-native link react-native-wonderpush-fcm 

iOS - Add push entitlement, background mode and service extension

Open the xcworkspace file of your project in Xcode:

open ios/*.xcworkspace

Add device capabilities

Select your app's main target and, under the Signing and Capabilities tab, click “+ Capability”

Add the following capabilities, one by one:

  • Background Modes,
  • Push Notifications.

Make sure the Remote notifications background mode is checked:

Create the notification service extension

In Xcode, select File / New / Target..., and choose Notification Service Extension:

Enter WonderPushNotificationServiceExtension as the name for your new target:

When Xcode prompts you to activate the new scheme, answer Cancel to keep Xcode building and debugging your app instead of the extension:

If you activate by mistake, switch back to your app's scheme from the dropdown menu located next to the play button.

Set the Deployment Target of your Notification Service Extension to 10.0:

Make sure to use Automatic Signing for the extension target:


If you're getting the following error, make sure to set up Automatic Signing for the extension:

Provisioning profile "XXX" has app ID "YYY", which does not match the bundle ID "YYY.WonderPushNotificationServiceExtension".

Edit the file ios/Podfile and add the following at the bottom:

target 'WonderPushNotificationServiceExtension' do
  platform :ios, '10.0'

  # Pods for WonderPushNotificationServiceExtension
  pod 'WonderPushExtension', '~> 4.0'
cd ios
pod install
open *.xcworkspace


If you get the following message: CocoaPods could not find compatible versions for pod "WonderPush", just run pod update and pod install again.

Step 4. Add required code

Take note of your Client ID and Client Secret from the Platforms tab of the Settings page:

Let's add the code that will prompt users to subscribe to push notifications. We recommend you place this code in a more suitable place in the user journey, but we'll do it at launch time for now. In your App class:

import React from 'react';

// Import WonderPush
import WonderPush from 'react-native-wonderpush';

const App: () => React$Node = () => {
  // Prompts users to subscribe to push notifications.
  // Move this in a more suitable place in the user journey.

  return (
    // ...

export default App;
import WonderPush from 'react-native-wonderpush';

export default class App extends Component {

  constructor() {
    // Prompts users to subscribe to push notifications.
    // Move this in a more suitable place in the user journey.
  render() {
    // ...


For Android

Open the Android Studio and configure the WonderPush Android SDK from your android/app/build.gradle file:

android {
  defaultConfig {
    // Note that it's important to keep the double quotes as part of the third argument
    // as this represents a string in Java code
    buildConfigField 'String', 'WONDERPUSH_CLIENT_ID', '"YOUR_CLIENT_ID"'
    buildConfigField 'String', 'WONDERPUSH_SENDER_ID', '"YOUR_SENDER_ID"'

Replace YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with the appropriate values you find in the Settings page.
Replace YOUR_SENDER_ID with the Firebase Sender ID from step 2.

WonderPush needs Android SDK 21, so you need to ensure your project does as well. Open android/build.gradle, find the line containing minSdkVersion and ensure it looks like this:

minSdkVersion = 21

Click Sync now in the banner that showed up in your editor, or click the Sync project with Gradle files button in the toolbar.
Then build your project.

For iOS

Open your AppDelegate and add the following, adapting YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with the values you've noted above:

import WonderPush

func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        WonderPush.setClientId("YOUR_CLIENT_ID", secret: "YOUR_CLIENT_SECRET")
        WonderPush.setupDelegate(for: application)
        return true
#import <WonderPush/WonderPush.h>
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [WonderPush setClientId:@"YOUR_CLIENT_ID" secret:@"YOUR_CLIENT_SECRET"];
    [WonderPush setupDelegateForApplication:application];
    [WonderPush setupDelegateForUserNotificationCenter];
    return YES;

Finally, we'll modify the code of the Notification Service Extension you created in Step 3. Replace the whole contents of NotificationService.swift or (NotificationService.h and NotificationService.m for Objective-C) with:

import WonderPushExtension

class NotificationService: WPNotificationServiceExtension {

    override class func clientId() -> String {
        return "YOUR_CLIENT_ID"

    override class func clientSecret() -> String {
        return "YOUR_CLIENT_SECRET"

#import <WonderPushExtension/WonderPushExtension.h>

@interface NotificationService : WPNotificationServiceExtension

#import "NotificationService.h"

@implementation NotificationService

+ (NSString *)clientId {
    return @"YOUR_CLIENT_ID";

+ (NSString *)clientSecret {
    return @"YOUR_CLIENT_SECRET";


Adapt YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with the values you've noted above, the same you just gave to your AppDelegate.

Receive your first push!

Use XCode or Android Studio to build and run your application and get the permission prompt you've configured:

Wait a couple of minutes and receive the default welcome notification:


Congratulations, you're done!
