# Transaction Notification

The Bell BASS Webhook API provides a mechanism for receiving real-time notifications about events in your application. Webhooks allow your application to react immediately to events such as transaction status updates, new payments, and other significant activities by receiving HTTP POST requests from the Bell BASS server.

### Key Features

1. **Setup Webhook:** Register a webhook URL to receive notifications for specific events.
2. **Webhook Notifications:** Receive real-time HTTP POST requests to your registered webhook URL whenever an event occurs.
3. **Verify Transaction:** Call transaction qeury endpoint using reference to verify the status and authenticity of the transaction.
