ASP.NET MVC4 Web API application defines post method to save customer. Customer is passed in json format in POST request body. Customer parameter in post method contains null values for properties.

How to fix this so that posted data will passed as customer object ?

If possible Content-Type: application/x-www-form-urlencoded should used since I dont know how to change it in javascript method which posts form.

Controller:

public class CustomersController : ApiController {

  public object Post([FromBody] Customer customer)
        {
            return Request.CreateResponse(HttpStatusCode.OK,
            new
            {
                customer = customer
            });
        }
    }
}

public class Customer
    {
        public string company_name { get; set; }
        public string contact_name { get; set; }
     }

Request:

POST http://localhost:52216/api/customers HTTP/1.1
Accept: application/json, text/javascript, */*; q=0.01
X-Requested-With: XMLHttpRequest
Content-Type: application/x-www-form-urlencoded; charset=UTF-8

{"contact_name":"sdfsd","company_name":"ssssd"}
