I have 2 web api actions in an ApiController-subclassed controller. The 2 action methods are POST. One method is working with non-null request body. But the other action method always get null request body. I do not know the reason why the second POST action does not work. Please help.

The following POST action method works OK with non-null request body binding: parameter "model" in method signature is bound correctly.

public HttpResponseMessage CreateAccount(Guid sessionid, UserAccountDto model)
var result = new HttpResponseMessage(HttpStatusCode.OK);

return Request.CreateResponse(HttpStatusCode.OK, model);

Dto class:

public class UserAccountDto
public long? AccountId { get; set; }
public string Email { get; set; }
public string Password { get; set; }
public string Salt { get; set; }
public string PlainTextPassword { get; set; }

Call with API by using Advanced Rest Client tool plugged in Chrome

POST http://localhost:55540/guests/create/13DD8111-8A00-48CE-997F-28EE3C88895D

plaintextpassword :"abc"

However, the 2nd ApiController POST action method does not work. Parameter "model" in method action is always null; it is not bound correctly for some reason.

public IHttpActionResult ConvertAccount(Guid sessionid, LinkedAccountThinDto model)
var accountType = model.AccountType;
var accountKey = model.AccountKey;

return Ok();
Custom Dto class:

public class LinkedAccountThinDto
public string AccountType { get; set; }
public string AccountKey { get; set; }

Call with API by using Advanced Rest Client tool plugged in Chrome:

POST http://localhost:55540/guests/convert/13DD8111-8A00-48CE-997F-28EE3C88895D

accounttype: “abcdf”,
accountkey: “1234567”

Try request format in below form:
"accounttype": "abcdf",
"accountkey": "1234567"

Add quotes to key name.

@nagendrathecoder. I tried to use quotes, but the problem was not solved. The problem happens for both testing Chrome-plugged-in tools I am using POSTMAN and Advanced Rest Client
