Hi. I have troubles with lib. Pls help) I think i made a stupid mistake. Whats wrong here?

public static string apiKey = "xxx";
public static string apiSecret = "yyy";
public static string apiPassword = "zzz";
static void Main(string[] args) {

 var clientOid = Guid.NewGuid().ToString().Replace("-", "");
 var body = new SortedDictionary <string,  object>();
 body.Add("clientOid", clientOid);
 body.Add("symbol", "BTC-LTC");
 body.Add("price", 0.1);
 body.Add("side", "BUY");
 body.Add("size", 0.6);
 body.Add("type", "LIMIT");

 var timestamp0 = Convert.ToInt64(Regex.Match(new WebClient().DownloadString("https://openapi-v2.kucoin.com/api/v1/timestamp"), "(?<=data\":).+(?=})").Value);

 var headers = GetRequestHeaders(HttpMethod.Post, "https://openapi-v2.kucoin.com/api/v1/orders",
  Convert.ToInt64(timestamp0), body);

 var request = (HttpWebRequest) WebRequest.Create("https://openapi-v2.kucoin.com/api/v1/orders");
 request.ContentType = "application/json";
 request.Method = "POST";

 foreach(KeyValuePair <string, string> entry in headers) {
  request.Headers.Add(entry.Key, entry.Value);
 }
 using(var streamWriter = new StreamWriter(request.GetRequestStream())) {
  string json = JsonConvert.SerializeObject(headers);
  streamWriter.Write(json);
 }

 var response = (HttpWebResponse) request.GetResponse();
 using(var streamReader = new StreamReader(response.GetResponseStream())) {
  var result = streamReader.ReadToEnd();
 }
}

private static Dictionary <string, string> GetRequestHeaders(HttpMethod httpMethod, string endpoint, long timestamp, SortedDictionary <string, object> body = null) {
 var headers = new Dictionary <string, string>();

 headers.Add("KC-API-KEY", apiKey);
 headers.Add("KC-API-SIGN", new Security().GetSignature(httpMethod.ToString(), endpoint, timestamp, apiSecret, body));
 headers.Add("KC-API-TIMESTAMP", timestamp.ToString());
 headers.Add("KC-API-PASSPHRASE", apiPassword);

 return headers;
}

You needed the endpoint when signing see here: https://github.com/mscheetz/KuCoinApi.Net/blob/v2.0/KuCoinApi.Net/KuCoinApi.Net/Core/Security.cs

In your case you'd pass '/api/v1/orders'
