How to send push notifications from Bubble

The simple truth is: Bubble cannot send native push notifications on its own. You must use an external push service (like OneSignal, Firebase, or Pushwoosh). Bubble’s job is to store the user’s push token and call the provider’s API (usually through the API Connector or a backend workflow).

How it Works

A push notification requires a device token. Your website or app can’t generate that itself. A push provider (for example OneSignal) generates it, and Bubble stores it inside the User. After this, when you want to send a push, Bubble triggers a backend workflow that calls the provider’s API with that token.

• User opens your app → push provider asks for permission → returns a token.
• You save that token into the User record in Bubble.
• You send the push by making an API call from a backend workflow.

Using OneSignal (most common for Bubble)

OneSignal is the easiest push provider for Bubble beginners. Bubble does not have a native plugin for it, but you can use the API Connector or the free community plugin.

• Create a OneSignal app → add your site/app domain.
• Install the OneSignal SDK on your Bubble page (HTML element) to collect tokens.
• Save the OneSignal Player ID into User’s field like “push\_id”.

Sending Push Notifications via API Connector

Create a backend workflow “send\_push” that accepts a User. Inside it, call OneSignal’s Notification API:

{
  "app_id": "YOUR-ONESIGNAL-APP-ID",
  "include_player_ids": ["<User's push_id>"],
  "contents": { "en": "Your message here" }
}

Set this as a POST call in API Connector to: https://onesignal.com/api/v1/notifications Include Authorization header: Authorization: Basic YOUR-REST-API-KEY

• Trigger this backend workflow when something happens (example: new message created).
• Bubble runs the API call → OneSignal sends the push → device receives it.

For Mobile Apps Built with BDK or Codeless Academy

If you're using a native wrapper, they give you a built‑in way to collect push tokens and trigger pushes. The workflow is the same: store the token → call their API to send pushes.

That’s the complete and correct flow: Bubble stores the push token and triggers an API call; the external service sends the push notification.
