Where [1, 2] - identifiers of participants of chat excluded creator.

Broadcasting settings:

To integrate it with Laravel broadcasting you can just update your broadcasting routes file ( routes/channels.php by default ) with next example:

...
use Saritasa\LaravelChatApi\Events\ChatCreatedEvent;  
use Saritasa\LaravelChatApi\Events\ChatEvent;
use Saritasa\LaravelChatApi\Contracts\IChatUser;
...
// Using model binding for chat events channel.
Broadcast::channel(ChatEvent::CHANNEL_PREFIX . '{chat}', function ($user, Chat $chat) {  
  // Checking that auth user is chat participant.
  return $chat->getUsers()->pluck('id')->contains($user->id);  
});  
  
Broadcast::channel(ChatCreatedEvent::CHANNEL_PREFIX . '{id}', function ($user, int $id) {  
  return (int)$user->id === $id;  
});

Read in official documentation about defining authorization callbacks. Now all chat events will dispatch through your broadcast driver.

Notifications settings:

To easy sent notifications you should create your own notification and update laravel_chat_api.php config file. Here is example if we should send notification when chat was reopened:

return [
	...
	'notifications' => [  
	   ... 
	  'chatReopened' => App\Notifications\MyOwnChatReopenedNotification::class,
	],
];
