Laravel api authorization with api_token

I am trying to create a Laravel API project. So I have this project with basic laravel's scaffolding set up. In my user migration I have added:

$table->string('api_token', 60)->unique();

then in my User.php model i have added:

 protected $fillable = [
    'name', 'email', 'password','api_token'
];

Then in my api.php i have made a test route:

Route::group(['middleware' => ['auth:api']], function(){

Route::get('/test', function (Request $request){
    return response()->json(['name' => 'test']);
});

});

so now i type this : with my api_token

localhost/project1/public/api/test?api_token='hsvdvhvsjhvasdvas8871238'

This is giving me this error:

PLease help! thanks in advance
