Laravel - Broadcasting - Broadcasting Events

Once you have defined an event and marked it with the ShouldBroadcast interface, you only need to fire the event using the event's dispatch method. The event dispatcher will notice that the event is marked with the ShouldBroadcast interface and will queue the event for broadcasting:

    
    use App\Events\OrderShipmentStatusUpdated;
    
    OrderShipmentStatusUpdated::dispatch($order);
