The solution depends on whether the parameter name is important. By default within Microsoft Web Api, the query string parameter name must match the parameter variable name of the method . For example:

If the url is

"api/MenuData/GetMenu?UserPKId=1"

then the controller method must have the following parameter list

public MyModel CommonWebApiMethod(string MethodName, string UserPKId)

Unimportant parameter name

Configure the route:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "MethodName",
            routeTemplate: "api/MenuData/{MethodName}",
            defaults: new { controller = "Common", action = "CommonWebApiMethod" }
        );
    }
}

Controller:

public class CommonController : ApiController
{
    [HttpPost]
    public MyModel CommonWebApiMethod(string MethodName, string parameter)
    {
        return new MyModel { MethodName = MethodName, Parameter = parameter };
    }
}

Calling url:

"api/MenuData/GetMenu?parameter=1"

Important parameter name

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "ParameterName",
            routeTemplate: "api/MenuData/{MethodName}/{parameterName}",
            defaults: new { controller = "Common", action = "CommonWebApiMethod" }
            );
    }
}

Controller:

public class CommonController : ApiController
{
    [HttpPost]
    public MyModel CommonWebApiMethod(string MethodName, string parameterName, string parameter)
    {
        return new MyModel { MethodName = MethodName, Parameter = parameter };
    }
}

Calling url:

"api/MenuData/GetMenu/UserPKId?parameter=1"
