The requested resource does not support http method 'GET' but using 'POST'

Question

My route is correctly configured as I already saw it in another questions. Web API uses MapHttpRoute , and it uses System.Web.Http . I decorated my Actions with [System.Web.Http.HttpPost] but it seems not to work and it returns the error message:

The requested resource does not support http method 'GET'

I tried this solution [System.Web.Http.AcceptVerbs("GET", "POST")] as I see here on the same question. The requested resource does not support HTTP method 'GET' and it worked.

But on the API Help Page , this is what I see

the METHOD of the Action is GET that that should be POST .

Maybe I am missing something that should not or should be implemented on the Action I am working with.

Here is my code in the Controller.

    [HttpPost, Route("DestroySession/{userID}", Name = "DestroySession"), AcceptVerbs("GET" , "POST")]
    public async Task<IHttpActionResult> DestroyUserSession(string userID)
    {
        SystemResult systemResult = new SystemResult();
        await Task.Run(() => {
            IAbstractLogic<UserInput, SystemResult> systemProcess = new LogoutLogic();
            UserInput userInput = new UserInput
            {
                UserID = userID
            };
            systemResult = systemProcess.doProcess(userInput);
        }).ConfigureAwait(false);
        return Content(HttpStatusCode.OK, new 
        { 
            message = systemResult.ResultMessage, status = systemResult.ResultCode == 0 
        });
    }

And here is my WebApiConfig

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

Any help would be much appreciated. Regards

Whooosh! It seems that my code is working very fine. I just tested it in POSTMAN and it literally works. All I can say is that if your request is to POST something. you need a third party application to test it out. Testing it on the browser alone gives you so much problem.
