Laravel sessions for API application

I added a question but,that was too long and now I am trying to be specific and to the point. I have a API workflow and structure of app is as below

 --ProjectDir
   |_angularDir
     |_Start
        |_bower_components
        |_node_modules          //front end dependencies
        |_gruntfile.js
  |_public                    //laravel public dir

We are using * grunt * as a build tool and it launches the app on http://localhost:9000. Now this takes me to a route http://localhost:9000/#/login. After I enter user name and password,I call the laravel route which is localhost/project_dir/public/login

   Route::post('login','LoginController@auth');

Controller

 public function auth()
  {  
     $rowInput =Request::all();
     $input = \Request::only('customer.email', 'customer.password');
     if(Auth::attempt(array_get($input, 'customer')))
   {
   //var_dump(Session::all());
    return \Response::json(['status'=>'success','url'=>$rowInput['customer']['redirectURL']]);
    }else {
    return \Response::json(['status'=>'fail','url'=>$rowInput['customer']['redirectURL']]);    
   }
}

The app enters in to the attempt method successfully,laravel creates a session,but then it does not persist. The user is redirected back to the login page.

I understand that I am sending request from a different domain (localhost:9000) and the response is from a different domain(localhost/proj_dir/public), but how can I handle these routes for this kind of workflow with laravel sessions.

The app worked fine till I had everything inside the public folder of laravel. But as I switched to this workflow it has created problems with sessions and I am stuck on this for a couple of days. PLease suggest the correct direction and if needed updates in the workflow.
