Question

I need to use StreamSend API to send email, here is
StreamSend API Reference

I am making web request as post to following URL with proper credentials

https://app.streamsend.com/audiences/2/blasts.xml

StringBuilder sb = new StringBuilder();
           sb.Append("https://app.streamsend.com/audiences/2/blasts.xml");
            Uri uri = new Uri(sb.ToString());
            HttpWebRequest request = WebRequest.Create(uri) as HttpWebRequest;
            request.ContentType = "application/xml";

            StringBuilder strMail= new StringBuilder();
            strMail.Append("<blast> ALL from api..... </blast>");

        byte[] data = Encoding.ASCII.GetBytes(strMail.ToString());
        Stream input = request.GetRequestStream();
        input.Write(data, 0, data.Length);
        input.Close();
        HttpWebResponse nsResponse = (HttpWebResponse)request.GetResponse();

i am having err# 422 or 500. i would appreciate any help.

A couple of things. First, it looks like you’re trying to do a POST request (you’re sending data in the request stream). If you really want a POST request, you have to set request.Method = "POST";

Also, if you want an XML response, you need to set the Accept header. According to the documentation you listed, you need: request.Accept = "application/xml";

And you need to add your login id to the request, as well. I’m not sure how that’s done. Perhaps in the request.Credentials property like this:

request.Credentials = new NetworkCredential("login_id", "your_key_here");

Finally, there’s no reason to use StringBuilder if all you’re doing is assigning strings. You can write, for example:

string urlString = "https://app.streamsend.com/audiences/2/blasts.xml" 
Uri uri = new Uri(urlString);

or

byte[] data = Encoding.ASCII.GetBytes("<blast> ALL from api..... </blast>");
