Почему я получаю ошибку 404 при реализации Stripe API Webhooks в. NET?

Question

Я пытаюсь внедрить Stripe для сбора платежей на моем сайте. Я могу получать платежи для обработки, но мне нужно получить HTTP POST от Stripe после оплаты, чтобы записать это в мою БД. Я использую Stripe CLI на своем локальном хосте и получаю ошибку 404. Я попытался опубликовать на // localhost: 59400 / api / payment и //localhost:59400/payment.

Вот документация Stripe, за которой я следую. NET https://stripe.com/docs/payments/checkout/fulfillment#webhooks

Вот мой контроллер:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNetCore.Mvc;
using System.IO;
using Stripe;
using System.Threading.Tasks;
using System.Data.Entity;
using System.Net.Http;
using System.Net;

namespace Stripe.Controllers
{
    [Route("api/[controller]")]  
    public class PaymentController : Controller
    {

        // You can find your endpoint's secret in your webhook settings
        const string secret = "XXX";

        private ApplicationDbContext db = new ApplicationDbContext();

        [HttpPost]
        public async Task<IActionResult> Index()
        {
            var json = await new StreamReader(HttpContext.Request.Body).ReadToEndAsync();

            // Set your secret key: remember to change this to your live secret key in production
            // See your keys here: https://dashboard.stripe.com/account/apikeys
            StripeConfiguration.ApiKey = "XXX";

            try
            {
                var stripeEvent = EventUtility.ConstructEvent(json,
                    Request.Headers["Stripe-Signature"], secret);

                // Handle the checkout.session.completed event
                if (stripeEvent.Type == Events.CheckoutSessionCompleted)
                {
                    var session = stripeEvent.Data.Object as Stripe.Checkout.Session;

                    // Fulfill the purchase...
                    //HandleCheckoutSession(session);

                    var paid = db.Confirmations.OrderByDescending(z => z.CreatedDate).First();
                    paid.Paid = true;
                    db.Entry(paid).State = EntityState.Modified;
                    await db.SaveChangesAsync();

                    return Ok();
                }
                else
                {
                    return Ok();
                }
            }
            catch (StripeException e)
            {
                return BadRequest();
            }
        }
    }
}

Я знаю, что CLI работает как localhost: 59400 / возвращает 200, но, очевидно, POST не попадает в API оплаты.

Я врезался в стену после нескольких недель попыток проработать это в свободное время. Любая помощь будет принята с благодарностью.

Вот мои RouteConfig и WebApiConfig соответственно

public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }

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

            // Web API routes
            config.MapHttpAttributeRoutes();

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