Push Notifications by One Signal
Overview
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 + OneSignal
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).
Push Notifications are available on Thunkable Pro, Business, and Team plans. While all Creators can add Push Notifications to their projects and live test them in their Android apps, only Creators on the previously mentioned plans can download and publish apps with Push Notifications. See our pricing page for more details.
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.

Follow the platform-specific configuration instructions below:
Android Configuration
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.
Copy Your App ID.
In the Android App ID field, paste Your App ID that you copied from OneSignal in step 3.
Click the Live Test on Device icon and open the Thunkable Live app on your device.

Android Testing
To test Android push notifications, download the app to your Android device and send a test message through OneSignal to see the push notification in action.
Toggle Location Permission (Android Only)
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.
