  so that what shape of function that represent response or how to make function represent response ?

  to clear more 

   public class Users
      {
          public string username { get; set; }
          public string password { get; set; }
          public string MessageStatus { get; set; }
          public int StatusCode { get; set; }
          public string StatusText { get; set; }
          public string client_ip { get; set; }
          public string BrowserInfo { get; set; }
          public List<Branches> Branches { get; set; }
          public string LoginTime { get; set; }
          public string browserinfo { get; set; }
      }
  which is correct number 1 or 2 .
  
  1- as following
  [HttpPost(Contracts.ApiRoutes.Login.UserLogin)]
  public IActionResult PostUserLogins([FromBody]Users user)
  {
  
  }
  2- as following
  
  public IActionResult PostUserLogins([FromBody]string username ,string password,string browserinfo,string client_ip,string )

  Hi ahmedbarbary,

  ahmedbarbary

  which is correct number 1 or 2 .

  The first one is correct.When receiving the data, you can only have one [FromBody] parameter. So that doesn't work for receiving multiple parameters (unless you can put all but one into the URL like this: https://localhost:44372/Security/Login?username=aa&password=bb).

  Best Regards,

  Rena

  Hi,

  You are using the ApiController attribute? By default complex types are taken from the body and simple types from the route or query string. If don't have any reason to change this, just stick with the default behavior.

  It is recommended to use the first option which passing object with json between client and server. 

  Do you have any issue with first option?
