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 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: .
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).
Notifications that are irrelevant and too frequent are often dismissed or blocked. We highly recommend sending notifications only when the content is relevant to the user. Examples include an e-commerce app letting the user know about a sale, or a game app letting the user know about a new level or feature.
To add Push Notifications to your app :
Navigate to your project's Blocks tab.
Locate Push Notification under the App Features heading.
Click the gear icon next to Push Notification.
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.

The first time your app is opened on a new device, it is automatically assigned a unique push notification user ID. This block returns the user's push notification user ID that can be used to send a notification to a specific user with a web API call.
