How to use WebRequest in c#

I'am trying to use example API call in below link; please check link:

http://sendloop.com/help/article/api-001/getting-started

My account is "code5" so I tried 2 codes to get systemDate.

  1. Code

     var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
 request.ContentType = "application/json; charset=utf-8";

 string text;
 var response = (HttpWebResponse)request.GetResponse();

 using (var sr = new StreamReader(response.GetResponseStream()))
 {
     text = sr.ReadToEnd();
 }

  2. Code

     HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
 httpWebRequest.Method = WebRequestMethods.Http.Get;
 httpWebRequest.Accept = "application/json";

But I don't know that I use correctly API by above codes ?

When I use above codes I don't see any data or anything.

How can I get and post API to Sendloop, and how can I use API by using WebRequest?

I will use API first time in .net so

any help will be appreciated.

Thanks.

    string userAuthenticationURI = 
    "https://maps.googleapis.com/maps/api/distancematrix/json?origins="+ originZip + 
    "&destinations="+ DestinationZip + "&units=imperial&language=en- 
     EN&sensor=false&key=Your API Key";

            if (!string.IsNullOrEmpty(userAuthenticationURI))
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(userAuthenticationURI);
                request.Method = "GET";
                request.ContentType = "application/json";
                WebResponse response = request.GetResponse();
                var responseString = new 
StreamReader(response.GetResponseStream()).ReadToEnd();
                dynamic obj = JsonConvert.DeserializeObject(responseString);

            }

It looks like you need to post your API key to the endpoint when making requests. Otherwise, you will not be authenticated and it will return an empty response.

To send a POST request, you will need to do something like this:

var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
request.ContentType = "application/json; charset=utf-8";

string postData = "APIKey=xxxx-xxxxx-xxxxx-xxxxx-xxxxx";

request.Method = "POST";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);
request.ContentLength = data.Length;
Stream newStream = request.GetRequestStream(); //open connection
newStream.Write(data, 0, data.Length); // Send the data.
newStream.Close();

string text;
var response = (HttpWebResponse)request.GetResponse();

using (var sr = new StreamReader(response.GetResponseStream()))
{
    text = sr.ReadToEnd();
}
