# JSONP (JavaScript Object Notation with Padding) = JSON data padded with JavaScript function name
so, something like this is being returned by WebAPI

callbackFunc({ "firstName": "sumit", "lastName": "jolly" });

# We need to set callback and data type attributes of Ajax request

# Install the JSONP MediaTypeFormatter, use NuGet
Install-Package WebApiContrib.Formatting.Jsonp

# Add a FormatterConfig class in App_Start folder:

public class FormatterConfig
{
public static void RegisterFormatters(MediaTypeFormatterCollection formatters)
{
var jsonFormatter = formatters.JsonFormatter;
jsonFormatter.SerializerSettings = new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver()
};

// Insert the JSONP formatter in front of the standard JSON formatter.
var jsonpFormatter = new JsonpMediaTypeFormatter(formatters.JsonFormatter);
formatters.Insert(0, jsonpFormatter);
}
}

# Add the following line in the Application_Start method of Global.ascx.cs:

FormatterConfig.RegisterFormatters(GlobalConfiguration.Configuration.Formatters);

you can send using AJAX calls say
$http.post(...) in AngularJS

or

$.post(...) in jQuery

Server doesn't allow for cross domain requests, this is security breach. To do this, server should enable CORS (http://enable-cors.org/) OR use JSONP (http://en.wikipedia.org/wiki/JSONP)
