WebAPIconfig for different parameter name for two controllers

Hi , 

I want two different controllers with two different parameter name 

I configured the WebAPIConfig as below but its not working. First one with parameter name as id and second with parameter name as tid.

config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);

config.Routes.MapHttpRoute(
name: "DefaultApi1",
routeTemplate: "api/{controller}/{tid}",
defaults: new { tid = RouteParameter.Optional }
);

Can any one suggest me how to do this?
