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:

namespace App\Jobs\Invoice;
use Illuminate\Bus\Batchable;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Throwable;
 
class CalculateSingleConsignment implements ShouldQueue
{
    use Batchable, Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
 
    // ... __construct() method, handle() method, etc.
 
    public function failed(Throwable $exception)
    {
        // Perform any action here when job has failed
     }
}
