Now, add the below annotations in app/Http/Controller/Controller.php

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;

class Controller extends BaseController

    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    /**

Now, run php artisan l5-swagger:generate and check api at https://mywebsite.com/api/documentation.
