Description: HTTP 404 for JSON return

i'm kinda new to programming c# and asp.net, i just want to build a rest api for my android app to sign in and sign up. but i face a problem for sign in (login).
the problem is i just wrote this codes below:

namespace CPanel.Controllers
{
    public class DashboardController : Controller
    {
        // GET: Dashboard
        public ActionResult CreateUser()
        {
            return View();
        }

        [HttpPost]
        public ActionResult CreateUser(string username,string password)
        {
            CPanel.Models.CPanelEntities1 db = new Models.CPanelEntities1();
            db.USP_AddUSer(username, password);
            return View();
        }


        [HttpPost]
        public ActionResult login(string username,string password)
        {
            CPanel.Models.CPanelEntities1 db = new Models.CPanelEntities1();
            try
            {
                var user = db.USP_Authenticate(username, password).First();
                return Json(new { UserId = user.UserId,Username=user.Username,IsAdmin=user.IsAdmin,Message="ok"});
            }catch(Exception)
            {
                return Json(new { message = "error" });
            }
        }
    }
}

the first part (CreateUser) work perfectly. but second part (login) only work on "Postman" chrome application.
i post a request on "Postman" -

localhost/dashboard/login?username=php&password=php

and i see a json:

{ "UserId": 29, "Username": "php", "IsAdmin": false, "Message": "ok" }

in localhost and wwwroot (iis) there in no chance and i face this error:

Server Error in '/' Application.

The resource cannot be found.

When you enter the http://localhost/dashboard/login?username=php&password=php url to web browser it issues a GET request, however your controller only accepts POST requests.

There's another thing, as far as I understand you need a web api but your example is a standard ASP.NET MVC controller. You might want to take a look on the following tutorial: https://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api
