How to parse parameters from WebRequest on Callback
===

OK, I'm working with a third party web API that uses web hooks to communicate when "something happens" on their end.  When "something happens" on their end, they send a POST request to my callback URL.

My question is once I catch that POST, how to extract the parameters from it?

I'm attempting to build an integration test scenario where I call my own callback URL with parameters attached so I don't have to go through the "how can I get their callbacks to hit my development machine" routine!

Here is how I'm trying to simulate, but not sure it this is a true representation of what a call to my callback URL might look like:

    [Test]
    public void {
    const string localCallbackUrl = "http://localhost/callback/callbackaction";
    HttpWebRequest request = WebRequest.Create(localCallbackUrl) as HttpWebRequest;
    request.Method = "POST";
    request.ContentType = "application/x-www.form-urlencoded";
    request.Accept = "application/json";

    string parameters = string.Format("param1={0}&param2={1}, "foo", "bar");
    byte[] byteArray = Encoding.UTF8.GetBytes(parameters);
    request.ContentLength = byteArray.Length;
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(byteArray, 0, byteArray.Length);
    dataStream.Close();

    var response = request.GetResponse();
    }

The call to "GetResponse()" is hitting my callback URL but I cannot find where the parameters live on the Request object.

NOTE: I am building the request in the same manner that I am building it to make calls to the API, but not 100% sure that is correct.
