Receiving Stripe.com's Webhooks in ASP.NET C#, MVC4

StripeWebhookController.cs

using System;
using System.IO;
using System.Web;
using System.Web.Mvc;
using Stripe; // you need this library https://github.com/jaymedavis/stripe.net
using System.Net;

namespace StripeSampleMVC.Controllers
{
    public class StripeWebhookController : Controller
    {

        [HttpPost]
        public ActionResult Index()
        {
            // MVC3/4: Since Content-Type is application/json in HTTP POST from Stripe
            // we need to pull POST body from request stream directly
            Stream req = Request.InputStream;
            req.Seek(0, System.IO.SeekOrigin.Begin);

            string json = new StreamReader(req).ReadToEnd();
            StripeEvent stripeEvent = null;
            try
            {
                // as in header, you need https://github.com/jaymedavis/stripe.net
                // it's a great library that should have been offered by Stripe directly
                stripeEvent = StripeEventUtility.ParseEvent(json);
            }
            catch (Exception ex)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest,"Unable to parse incoming event");
            }

            if (stripeEvent ==null)
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest, "Incoming event empty");

            switch (stripeEvent.Type)
            {
                case "charge.refunded":
                    // do work
                    break;

                case "customer.subscription.updated":
                case "customer.subscription.deleted":
                case "customer.subscription.created":
                    // do work
                    break;
            }

            return new HttpStatusCodeResult(HttpStatusCode.OK);
        }
    }
}

You might want to add something like this before the switch statement:

var obj = JObject.Parse(json);
var dataObj = obj.SelectToken("data.object"); //this gets the event data object payload only

and then in the cases you can use something like this:

case "customer.subscription.created":
var subscription = Mapper<StripeSubscription>.MapFromJson(dataObj.ToString());
....

This way you can have a strongly typed object to work with instead of the data.object dynamic class of the stripeEvent. For each case the payload would be a different type, so you can check the stripe api and create objects that are easier to work with in your code. (I was unaware that there was a Mapper<> in Stripe.net, made things easy because it converts the unix dates from the json properly)

just use the code from https://github.com/jaymedavis/stripe.net#events
