public class ApiRoutes
{
public const string SecurityBase = "Security";
public static class Security
{
public const string GetUserMenus = SecurityBase + "/UserPrograms/{userId}";
}
//Api url For Login
public const string SecurityLogin = "Authuntication";
public static class Login
{
public const string UserLogin = SecurityLogin + "/login";

}
}
```
public class MenusController : Controller
    {
        readonly Services.ISecurityService _SecurityService;
        public MenusController(Services.ISecurityService securityService)
        {
            _SecurityService = securityService;
        }
        [HttpGet(Contracts.ApiRoutes.Security.GetUserMenus)]
        public IActionResult GetUserMenu(string userId)
        {
            string strUserMenus = _SecurityService.GetUserMenus(userId);
            return Ok(strUserMenus);
        }
        [HttpPost(Contracts.ApiRoutes.Login.UserLogin)]
        public IActionResult PostUserLogins([FromBody] Users user)
        {
}
public class MenusController : Controller
    {
        readonly Services.ISecurityService _SecurityService;
        public MenusController(Services.ISecurityService securityService)
        {
            _SecurityService = securityService;
        }
        [HttpGet(Contracts.ApiRoutes.Security.GetUserMenus)]
        public IActionResult GetUserMenu(string userId)
        {
            string strUserMenus = _SecurityService.GetUserMenus(userId);
            return Ok(strUserMenus);
        }
        [HttpPost(Contracts.ApiRoutes.Login.UserLogin)]

This is incorrect...
```
 authunticationcontroller/PostUserLogin
```
Remove "controller"
```
 authuntication/PostUserLogin
```
IMHO, your routing design is very confusing and overly complex. It was suggested in your duplicate thread to use standard routing. Why obfuscate the the route with a static property? There's no benefit unless the goal is to make your code hard to read.

Secondly, the login action is in the Menus Controller? Why? Just put the login in an Account Controller or Authentication Controller.

Again, your code is very very confusing. Unfortunately, like your other threads the shared code does not compile. Clearly the shared code is not the actual code that you are testing.

I built a simple test controller based in your code and it works just fine. I feel it is confusing to route authentication/login to the menus controller but this is your code and can be as confusing as you like.

    public class MenusController : Controller
    {
        public IActionResult Index()
        {
            return Ok("Index");
        }

        //GET: Security/UserPrograms/{userId}
        [HttpGet(Contracts.ApiRoutes.Security.GetUserMenus)]
        public IActionResult GetUserMenu(string userId)
        {
            return Ok(userId);
        }

        //POST: Authuntication/login
        [HttpPost(Contracts.ApiRoutes.Login.UserLogin)]
        public IActionResult PostUserLogins([FromBody] Users user)
        {
            return Ok(user.Username);
        }
    }

    public class Users
    {
        public string Username { get; set; }
    }

Just be aware this design is very irritating because you force anyone trying to help you to read the code below to find the route. Why make your code so complex?

    public class ApiRoutes
    {
        public const string SecurityBase = "Security";
        public static class Security
        {
            public const string GetUserMenus = SecurityBase + "/UserPrograms/{userId}";
        }
        //Api url For Login
        public const string SecurityLogin = "Authuntication";
        public static class Login
        {
            public const string UserLogin = SecurityLogin + "/login";

        }
    }

Anyway, I configure the PostMan to POST to URL https://localhost:44327/Authuntication/login. With a body of...

{
	"Username": "Foo Bar"
}

.. and it just works.
