Try This one :)

{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://your json URL");

                //&tracking_number=" + txtttnumber.Text + "&courier=" + ddlcourier.SelectedValue

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                if (response.StatusCode == HttpStatusCode.OK)
                {
                    Stream receiveStream = response.GetResponseStream();
                    StreamReader readStream = null;

                    if (response.CharacterSet == null)
                        readStream = new StreamReader(receiveStream);
                    else
                        readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
                    //  List<string> list = new List<string>();
//Convert JSON object into String
                    string data = readStream.ReadToEnd();
//Convert JSON object into Dictionary
 Dictionary<string, object> dict = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(data);

                  
//Convert into variable
                    var GridData= dict["checkpoints"];

GridView1.DataSource=GridData;
GridView1.DataBind();

//
//


                         }
 }
