Perform Action when Job has failed

In some cases, we want to perform some action when job has failed. For example, send an email or a notification.

For this purpose, we can use failed() method in the job class, just like the handle() method:

 1namespace App\Jobs\Invoice;
 2use Illuminate\Bus\Batchable;
 3use Illuminate\Bus\Queueable;
 4use Illuminate\Queue\SerializesModels;
 5use Illuminate\Queue\InteractsWithQueue;
 6use Illuminate\Contracts\Queue\ShouldQueue;
 7use Illuminate\Foundation\Bus\Dispatchable;
 8 
 9class CalculateSingleConsignment implements ShouldQueue
10{
11    use Batchable, Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
12 
13    // ... __construct() method, handle() method, etc.
14 
15    public function failed()
16    {
17        // Perfom any action here when job has failed
18     }
19}
