How to insert data from access token request?

Hi guys,

My customer send a url like this;

https://accounts.zoho.com/oauth/v2/token?refresh_token={refreshToken}&client_id={client_id}&client_secret={client_secret}&grant_type=refresh_token

I want to write a insert code according to this. My code is below but I'm not sure this code is true. I didn't find document about how can I send to data from access token request.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://accounts.zoho.com/oauth/v2/token?refresh_token={refreshToken}&client_id={client_id}&client_secret={client_secret}&grant_type=refresh_token");

request.Method = "POST";

JObject requestBody = new JObject();

JArray recordArray = new JArray();

JObject recordObject = new JObject();

recordObject.Add("First_Name", contactData.FirstName);

recordObject.Add("Mobile", contactData.PhoneNumber);

recordObject.Add("Email", contactData.Email);

recordObject.Add("Kategori", contactData.MessageType);

recordObject.Add("Konu", contactData.Subject);

recordObject.Add("Last_Name", contactData.LastName);

recordObject.Add("Company", contactData.CompanyName);

recordObject.Add("Sirketiniz_ile_ilgili_ozet", contactData.CompanySummary);

recordArray.Add(recordObject);

requestBody.Add("data", recordArray);

string dataString = requestBody.ToString();

var data = Encoding.UTF8.GetBytes(dataString);

int dataLength = data.Length;

request.ContentLength = dataLength;

using (var writer = request.GetRequestStream())

{

writer.Write(data, 0, dataLength);

}

request.KeepAlive = true;

HttpWebResponse response;

try

{

response = (HttpWebResponse)request.GetResponse();

}

catch (WebException e)

{

if (e.Response == null) { throw; }

response = (HttpWebResponse)e.Response;

}

HttpWebResponse responseEntity = response;

Console.WriteLine("HTTP Status Code : " + (int)response.StatusCode);

string responsestring = new StreamReader(responseEntity.GetResponseStream()).ReadToEnd();

responseEntity.Close();

Console.WriteLine(responsestring);
