Scenario: The Web API must only accept one data format.
The MVC front-end layer and the Web API will communicate by using JSON.
The most common approach to support JSON only is to clear other formatters and leave only JsonMediaTypeFormatter around Given an instance of HttpConfiguration you’d simply clear all and re-add JsonMediaTypeFormatter:
configuration.Formatters.Clear();
configuration.Formatters.Add(new JsonMediaTypeFormatter());
