Sending Push Notifications

Before you start

• Configured Firebase module
• At least one registered token or a direct test token

Configure and verify

1. Open Push Notification

   The page appears after Firebase is enabled for the app. Review connection and subscriber status first.

2. Choose the audience

   Select all registered devices, a saved identity, or a direct FCM token for isolated testing.

3. Write the message

   Add a title or body. Optionally include an HTTPS image URL, an in-app Open URL, and a JSON object of non-sensitive custom data.

4. Send and review

   Submit the message and review attempted, sent, and failed counts. A no_subscribers result means no token matched the audience.

5. Test delivery states

   Test foreground, background, terminated app, denied permission, and notification-tap URL handling.
