Laravel: How to limit retries on queued notifications - laravel

Question

From the Laravel manual, I understand that I can limit the number of times a queued job is retried using either the command line (when starting the queue), or by setting the $tries property on the job class itself. https://laravel.com/docs/5.6/queues#max-job-attempts-and-timeout
I want to set the maximum number of retries within the job itself, not using the command line, however the job is actually a custom class that inherits from Illuminate\Notifications\Notification, not an App\Job. In this case, is it possible to limit the number of tries?
I tried setting the $tries property in my customer notification, but it had no effect. I am using a custom channel as well, but setting the $tries there had no effect either.

Answer 1

In your notification file add the Queueable trait. It's this trait that gives you the possibility to alter the number of tries.
use Illuminate\Bus\Queueable;
class MyNotification extends Notification implements ShouldQueue
{
use Queueable;
public $tries = 3;

Answer 2

As of Laravel 5.7+, you can easily limit maximum tries by adding $tries property to the Queueable Notification.
Usage example from the PR author (laravel/framework GitHub PR 26493#):
<?php
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class TestNotification extends Notification implements ShouldQueue
{
use Queueable;
public $tries = 3; // Max tries
public $timeout = 15; // Timeout seconds
/**
* Create a new notification instance.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Get the notification's delivery channels.
*
* #param mixed $notifiable
* #return array
*/
public function via($notifiable)
{
return ['mail'];
}
/**
* Get the mail representation of the notification.
*
* #param mixed $notifiable
* #return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->line('The introduction to the notification.')
->action('Notification Action', url('/'))
->line('Thank you for using our application!');
}
}
