Answer 1

Please check if you are using the Live credentials(accountSid,authToken) on your Twilio Account.

The API does the post already:

You don't need all this code below.

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        var authInfo = accountSid +":"+ authToken;
        authInfo = Convert.ToBase64String(Encoding.UTF8.GetBytes(authInfo));
        request.Method = "POST";
        var postData = "{\"To\":" + "\"" + sms.ToNumber + "\"" + ", \"From\":" + "\"" + fromNumber + "\"" + ", \"Body\":" + "\"" + sms.Body + "\"}";

        var data = Encoding.UTF8.GetBytes(postData);
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;
        Stream writer = null;
        writer = request.GetRequestStream();
        writer.Write(data, 0, data.Length);
        writer.Close();
        request.Headers["Authorization"] = "Basic " + authInfo;
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        StreamReader reader = new StreamReader(response.GetResponseStream());
        string content = reader.ReadToEnd();
