Sending Google Analytics events programatically from server side not working

We want to send custom event tracking information to google analytics from server side.

For this I have referred this SO post, and come up with the following code snippet, but somehow it is not sending the events' information to GA. I've debugged the code to see the response, and it is returning 200 (OK) status, with response similar to what when the event is tracked through client side. We have waited for a couple of days to see if the event is tracked, but it doesn't.

    public static void TrackEvent(string category, string action, string label)
    {
        string gaCodeTest = "UA-xxxxxx-2";
        ASCIIEncoding encoding = new ASCIIEncoding();
        string cid = Guid.NewGuid().ToString();

        string postData =
            "v=1&tid=" + gaCodeTest + " &cid=" + cid + "&t=event" +
            "&ec=" + category +
            "&ea=" + action +
            "&el=" + label;

        byte[] data = encoding.GetBytes(postData);
        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://www.google-analytics.com/collect");

        myRequest.Method = "POST";
        myRequest.ContentType = "application/x-www-form-urlencoded";
        myRequest.ContentLength = data.Length;
        Stream newStream = myRequest.GetRequestStream();
        newStream.Write(data, 0, data.Length);

        var response = (HttpWebResponse)myRequest.GetResponse();

        //var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

        newStream.Close();

    }

Solution

Your request.

v=1&tid=UA-1111111-2 &cid=555&t=event&ec=MyCategory&ea=MyAction&el=MyLabel

test it at the debug end point

https://www.google-analytics.com/debug/collect?v=1&tid=UA-11111-2 &cid=555&t=event&ec=MyCategory&ea=MyAction&el=MyLabel

results in

{
  "hitParsingResult": [ {
    "valid": false,
    "parserMessage": [ {
      "messageType": "ERROR",
      "description": "The value provided for parameter 'tid' is invalid. Please see  for details.",
      "messageCode": "VALUE_INVALID",
      "parameter": "tid"
    } ],
    "hit": "/debug/collect?v=1\u0026tid=UA-76874663-2%20\u0026cid=555\u0026t=event\u0026ec=MyCategory\u0026ea=MyAction\u0026el=MyLabel"
  } ],
  "parserMessage": [ {
    "messageType": "INFO",
    "description": "Found 1 hit in the request."
  } ]
}

You have a space after tid
