CSRF Token Error / 419

In Laravel, you can handle CSRF Token Errors (status code 419) by customizing the "VerifyCsrfToken middleware", which is located in the "app/Http/Middleware/VerifyCsrfToken.php" file. To address this error, you need to declare the success, fail, and cancel URLs/routes in the middleware.

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as Middleware;
class VerifyCsrfToken extends Middleware
{
    protected $except_urls =  
    'your/success_url',
        'your/fail_url',
        'your/cancel_url',
    ];
   
}
