Web API calling Error ASP.Net MVC

Question

I am developing a web api but it can not hit it. Error shows 404 not Found.

Web Api

using Atea.Azure.ApiMangement.Business;
using System.Web.Http;

namespace Azure_API_Delegation_Portal.Controllers
{
    [RoutePrefix("api/apim")]
    public class ApimController : ApiController
    {
        private readonly ISubscriptionService _subscriptionService;
        [HttpGet]
        [Route("{string:productId}")]
        public bool GetProductSubscribe(string productId)
        {
            return _subscriptionService.IsSubscribed(productId);
        }
    }
}

How I call an API https://localhost:44300/api/apim/ldkjfk232

Web API Route

using System.Web.Http;

namespace Azure_API_Delegation_Portal
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.MapHttpAttributeRoutes();

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

I am missing this line of code in Application_Start() function in "Global.asax" file.

GlobalConfiguration.Configure(WebApiConfig.Register);

Fix your route template. It is string by default so no need for the string constraint

//GET api/apim/ldkjfk232"
[HttpGet]
[Route("{productId}")]
public bool GetProductSubscribe(string productId)

Also note that the constraint goes after the placeholder name like this example

[Route("{paramaterName:int}")]

Read more about attribute routing here : Attribute Routing in ASP.NET Web API 2

It will show you how to properly configure your web api.
