No HTTP resource was found that matches the request URI in Web API

Question

I have configured my WebApiConfig like this:

public static void Register(HttpConfiguration config)
{
    config.Routes.MapHttpRoute(
        name: \"DefaultApi\"         


        

Answer 1

Your request URL is http://localhost:8598/api/WebApi/GetLocationCategory/87

Your route is configured to accept: 'api/{controller}/{action}/{id}'

So you need to ensure that the name of your controller is 'WebApiController'.

Also, as stated alredy by @SDG you need to make sure that the name of the parameter to your action method matches what you have in your Route template i.e change 'CatID' to 'id'
