Google Analytics Measurement Protocol – Track Events C#

Recently I had a project that required to track events happening within the business layer and could not be tracked using JavaScript from the client. To do this a helper class was required in order to communicate with Google Analytics and track those extra events. Below you will find that class that can be used to do Page Tracking, Event Tracking, Ecommerce Tracking, Social Interactions and Exception Tracking within your C# code without requiring any JavaScript or any other script.

        private string googleVersion = "1";
        private string googleTrackingID = "UA-XXXX-Y";
        private string googleClientID = "555";

        public GoogleTracker(string trackingID)
        {
            this.googleTrackingID = trackingID;
        }

        public void trackEvent(string category, string action, string label, string value)
        {
            Hashtable ht = baseValues();
            
            ht.Add("t", "event");                   // Event hit type
            ht.Add("ec", category);                 // Event Category. Required.

        {
            Hashtable ht = baseValues();

            {
                if (data != "") data += "&";
                if (values[key] != null) data += key.ToString() + "=" + HttpUtility.UrlEncode(values[key].ToString());
            }
            
            using (var client = new WebClient())
            {
                var result = client.UploadString(googleURL, "POST", data);                               
            }

            return true;
        }
    }
}

All you need to do afterwards initialize the class using the code below:

Spyriadis.net.GoogleTracker ga = new Spyriadis.net.GoogleTracker("UA-XXXXXXX-X");

And then you can use all the functions by Google as described here. For example to track an event you use:

ga.trackEvent("Category", "Action", "label", "value");

You can pass null values for all the non-required fields.
