To send push notifications from Django, you can use the Firebase Admin SDK alongside Django models for device token management and Celery with Redis to process event-driven notification delivery asynchronously.

Device tokens are registered by exposing REST endpoints that capture the token from mobile devices and store it using a dedicated DeviceToken model, enabling the backend to target specific iOS and Android devices.

Yes, Celery and Redis can be used for asynchronous push notification delivery by offloading the Firebase Admin SDK message dispatch to background tasks, preventing blocking during booking state changes.

Notification preferences are managed through a PushNotificationPreference model and API endpoints, allowing the system to respect user settings before triggering event-driven push notifications.

The best way to trigger push notifications for booking state changes is through a signal-driven architecture that emits events to Celery tasks, which then execute Firebase Cloud Messaging delivery.

You need REST endpoints to unregister devices and manage the DeviceToken records, ensuring the Firebase Admin SDK no longer attempts to deliver push notifications to inactive or revoked user tokens.
