how to send json data by $http.Post from Angular to webAPI POST method?

I am trying to pass data as JSON object by $http.Post to webAPI method. In WebAPI method, the parameter of the method is a class object.

It works fine when I test the webAPI method by Postman.But I am not able to pass the JSON object by angular $http.post method-I get null values in the webAPI parameter(in the class object).

Can someone please advise how to fix the issue.i am new to AngularJS.Kindly help.

AngularJS Code

angular.module('Test.Employer')
    .controller('EmployerController', ['$scope','headerValue', '$http',
        function ($scope, headerValue, $http) { 
            var ipEmployerDetls = {                   
                EmployerName: "cherokee",
                Company: "ABC"                   
            };

            $http({ 
                url: "http://localhost:212122/api/Values/PostEmployeeData",
                dataType: 'json', 
                method: 'POST', 
                data: JSON.stringify(ipEmployerDetls), 
                headers: { 
                    "Content-Type": "application/json" 
                } 
            }).success(function (response) { 
                $scope.object = response.data;
            }) 
                .error(function (error) { 
                    alert(error.Message); 
                });
})();

WebAPI

using System.Web.Http;
using AttributeRouting.Web.Http;

namespace webAPITestProject.Controllers
{
    [Route("api/Values")] 
    public class ValuesController : ApiController
    {
        retrieveEmployeeData empData = new retrieveEmployeeData();
        retrieveProductDetails prodDetls = new retrieveProductDetails();    

        [Route("PostEmployeeData")] 
        [HttpPost]
        public DataTable PostEmployeeData([FromBody] Employer empDetails)
        {
            DataTable dataTable = new DataTable { TableName = "MyTableName" };
            dataTable = empData.getEmployeeData(empDetails);
            return dataTable;
        }
    }
}

NOTE: I get NULL value in empDetails in webAPI method,but when I test the method in Postman,it has value.

Your routing attributes don't look right for how you've specified your $http API call.

Looks like you want the class-level attribute to be:

[RoutePrefix("api/Values")]
public class ValuesController : ApiController

Which will mean that PostEmployeeData has a route of api/Values/PostEmployeeData.

You'll also need to ensure that your properties in ipEmployerDetls directly map to your Employer class (which you haven't shown), so that model binding works correctly.
