Lumen JWT send token with requests

Authentication is working, I have a few routes under auth middleware, Whenever i request it throws :

{
  "message": "Failed to authenticate because of bad credentials or an invalid authorization header.",
  "status_code": 401
}

How can i send the token with the request like :

Authorization bearer 

It works with `postman`, How can i send the token with request header, Or in any other best way.

Route :

$api->get('/categories', [
    'uses' => 'App\Http\Controllers\CategoryController@index',
    'as' => 'api.categories',
]);

Method :

public function index() {
    $lessons = \App\Category::all();
    $token = JWTAuth::getToken(); // $token have jwt token

    return response()->json([
        'data' => $lessons,
        'code' => 200,
    ]);
}
