Push notifications are one of the biggest advantages of mobile apps over mobile websites since they can send messages to users without the app being open.
When a user first opens an app with push notifications enabled they receive an alert prompting them to enable push notifications. Once they accept they are a subscriber of your app's push notifications.
Thunkable utilizes the services of OneSignal to facilitate push notifications from your app. OneSignal is a free service that supports unlimited devices and notifications. You can learn more about their features here: OneSignal pricing page.
To send push notifications to your app's users, you must link your Thunkable app to your OneSignal apps (iOS and/or Android). Once you've added your OneSignal App IDs into Thunkable, the work in Thunkable is done, and the remainder of the management takes place in third-party platforms (OneSignal, Apple Developer, and Firebase, depending on the platform).
This feature may only be available for Creators on certain Thunkable plans. Please refer to our pricing page for more information: Thunkable pricing.
Push notifications are one of the biggest advantages that mobile apps have over mobile websites, since they can send messages to users without the app being open.
However, annoying notifications---those that are irrelevant and too frequent---can be dismissed or blocked easily. We highly recommend sending notifications only when the content is relevant to the user. Examples of this include an e-commerce app notifying users of a sale, or a game notifying users of new levels and features.
Push Notifications cannot be tested with the Thunkable Live app on iOS You can test Push Notifications on iOS by publishing your app to TestFlight and downloading it from there.
To add Push Notifications to your app :
Drag and drop the component onto any screen.
That's it. There are no blocks needed.
Click Push Notification at the bottom of the screen
The Push Notification settings modal opens. This is where you will enter your OneSignal Android App ID and OneSignal iOS App ID to configure the connection between OneSignal and your Thunkable project.

Go to OneSignal.
Click Sign Up.
Create your account and complete the OneSignal onboarding.
If you didn't create an app as part of the OneSignal onboarding, navigate to your OneSignal dashboard and click + New App/Website.
If you intend to send push notifications to your app's users on Android and iOS you will need to create a new app in OneSignal for each, Android and iOS.
Enter your app name. We recommend including the platform in your app name, for example, Employee Directory - Android or Employee Directory - iOS.
Select Apple iOS (APNs) or Google Android (FCM).
Click Next: Configure Your Platform.
Follow the platform-specific configuration instructions below:
A Google Service Account is a special type of account from Google that applications use to make authorized calls to a variety of APIs, including Firebase Cloud Messaging APIs. For more details, see Google's own documentation on Service Accounts. In order to send push notifications to Android devices, you will need a Service Account to generate a private key for OneSignal to utilize.
If you don't already have one, create a Firebase account. Instructions for getting started with Firebase are available here: Firebase Account Setup.
Follow OneSignal's instructions to generate Firebase Cloud Messaging API Credentials for sending Android App Notifications here: Android: Firebase Credentials.
To continue sending messages in 2024, you need to provide updated authentication credentials from Firebase for all apps created in OneSignal before September 1, 2023:
In your Firebase project, go to Project settings and the Service accounts tab to download your private key JSON.
In your OneSignal App Settings, upload the private key file you just downloaded
More information on these steps is available here: Android: Firebase Credentials.
Select Native Android as your target SDK.

OneSignal is a powerful choice of push provider. With their platform, you can setup for your users to be pushed notifications based on their locations. This is optional, however. This also means you need to make a conscious decision as to whether or not to track your Android users geographical locations. These tracking data can be accessed via the OneSignal dashboard. This feature can be toggled on and off in the Push Notifications settings by clicking on the icon at the bottom of your design screen.
If you enable Geolocation Permissions, when you publish your app, ensure that you indicate that you're tracking location when you publish your app.
