I’m am trying to build & register a webhook in Stripe to handle the invoice.paid event. There is a walkthrough (see: https://docs.stripe.com/webhooks) detailing how it should be done. I’ve followed it and implemented their suggestions but my webhook controller is failing to receive the event from Stripe. It is giving a 404 error and saying that the resource cannot be found.

This is my code:

  [Route("api/[controller]")]
  public class StripeWebHook : Controller
  {
      private Entities db = new Entities();

      private string endpointSecret = "whsec_YuF7Vgxd2V3Jh2zZKj7aRLDQ2RiQBPtN";

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

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

              // Handle the event
              if (stripeEvent.Type == Events.InvoicePaid)
              {
                  Stripe.Invoice invoice = stripeEvent.Data.Object as Stripe.Invoice;
                  // Then define and call a method to handle the successful payment intent.
                  _handleInvoicePaid(invoice);
              }
              else if (stripeEvent.Type == Events.PaymentMethodAttached)
              {
                  var paymentMethod = stripeEvent.Data.Object as PaymentMethod;
                  // Then define and call a method to handle the successful attachment of a PaymentMethod.
                  // handlePaymentMethodAttached(paymentMethod);
              }
              // ... handle other event types
              else
              {
                  // Unexpected event type
                  Console.WriteLine("Unhandled event type: {0}", stripeEvent.Type);
              }
              return new HttpStatusCodeResult(System.Net.HttpStatusCode.OK);
          }
          catch (StripeException e)
          {
              return new HttpStatusCodeResult(System.Net.HttpStatusCode.BadRequest);
          }
      }
   }
}

I have registered the endpoint in Stripe as https://smallshinycar54.conveyor.cloud/api/StripeWebHook. Just assume the website name is correct (it’s conveyor – a utility used to make your local applications available on the internet).

I don’t see why the API is not being hit.

When I trigger the event using the Stripe CLI like so: stripe trigger invoice.paid. All I see in my workbench is the 404 error.

I’m not sure what I need to do to get it to work properly.
Please advise.
