Not receiving any data from the BitStamp API

0 votes

I have a code but when I execute it, RestSharp BitStamp Authentication fails and I get error:

{"error": "Missing key, signature and nonce parameters"}

The code I am using is as follows:

public ActionResult Index()

        {

            const string BaseUrl = "https://www.bitstamp.net/api/balance/";

            var client = new RestClient();

            var request = new RestRequest();


            client.BaseUrl = BaseUrl;

            AddApiAuthentication(request);

            var response = client.Execute(request);

            var foo = response.Content;

            //{"error": "Missing key, signature and nonce parameters"}

            return View();

        }


        public void AddApiAuthentication(RestRequest restRequest)

        {

            var nonce = DateTime.Now.Ticks;

            var signature = GetSignature(nonce, apiKey, apiSecret, clientId);


            restRequest.AddParameter("key", apiKey);

            restRequest.AddParameter("signature", signature);

            restRequest.AddParameter("nonce", nonce);


        }


        private string GetSignature(long nonce, string key, string secret, string clientId)

        {

            string msg = string.Format("{0}{1}{2}", nonce, clientId, key);

            return ByteArrayToString(SignHMACSHA256(secret, StrinToByteArray(msg))).ToUpper();

        }


        public static byte[] SignHMACSHA256(String key, byte[] data)

        {

            HMACSHA256 hashMaker = new HMACSHA256(Encoding.ASCII.GetBytes(key));

            return hashMaker.ComputeHash(data);

        }


        public static byte[] StrinToByteArray(string str)

        {

            return System.Text.Encoding.ASCII.GetBytes(str);

        }


        public static string ByteArrayToString(byte[] hash)

        {

            return BitConverter.ToString(hash).Replace("-", "").ToLower();

        }

How to make this work?

I saw a code online that was used for their project. It is as follows:

public class BitstampAuthenticatedRequest : RestRequest

{

    #region Data

    private readonly string _clientId = "xxxxx"; // Numbers


    private readonly string _apiKey = "xxxxx"; // Random numbers and letters

    private readonly string _apiSecret = "xxxx"; // Random numbers and letters


    private long Nonce = DateTime.Now.Ticks;


    #endregion


    #region Constructor


    public BitstampAuthenticatedRequest(string resource, Method method)

    : base(resource, method)

    {

        this.AddParameter("key", _apiKey);           

        this.AddParameter("nonce", Nonce);

        this.AddParameter("signature", CreateSignature());

    }


    #endregion


    #region Methods


    private string CreateSignature()

    {

        string msg = string.Format("{0}{1}{2}", Nonce,

            _clientId,

            _apiKey);


        return ByteArrayToString(SignHMACSHA256(_apiSecret, StringToByteArray(msg))).ToUpper();

    }


    private static byte[] SignHMACSHA256(String key, byte[] data)

    {

        HMACSHA256 hashMaker = new HMACSHA256(Encoding.ASCII.GetBytes(key));

        return hashMaker.ComputeHash(data);

    }


    private static byte[] StringToByteArray(string str)

    {

        return System.Text.Encoding.ASCII.GetBytes(str);

    }


    private static string ByteArrayToString(byte[] hash)

    {

        return BitConverter.ToString(hash).Replace("-", "").ToLower();

    }


    #endregion

}


For our new application we used the following code:

public class BitstampAuthenticatedRequest : RestRequest

{

    #region Data

    private readonly string _clientId = "xxxxx"; // Numbers


    private readonly string _apiKey = "xxxxx"; // Random numbers and letters

    private readonly string _apiSecret = "xxxx"; // Random numbers and letters


    private long Nonce = DateTime.Now.Ticks;


    #endregion


    #region Constructor


    public BitstampAuthenticatedRequest(string resource, Method method)

    : base(resource, method)

    {

        this.AddParameter("key", _apiKey);           

        this.AddParameter("nonce", Nonce);

        this.AddParameter("signature", CreateSignature());

    }


    #endregion


    #region Methods


    private string CreateSignature()

    {

        string msg = string.Format("{0}{1}{2}", Nonce,

            _clientId,

            _apiKey);


        return ByteArrayToString(SignHMACSHA256(_apiSecret, StringToByteArray(msg))).ToUpper();

    }


    private static byte[] SignHMACSHA256(String key, byte[] data)

    {

        HMACSHA256 hashMaker = new HMACSHA256(Encoding.ASCII.GetBytes(key));

        return hashMaker.ComputeHash(data);

    }


    private static byte[] StringToByteArray(string str)

    {

        return System.Text.Encoding.ASCII.GetBytes(str);

    }


    private static string ByteArrayToString(byte[] hash)

    {

        return BitConverter.ToString(hash).Replace("-", "").ToLower();

    }


    #endregion

}

And you have to call it as follows:

        // Decide which url to use

        var baseUrl = "https://www.bitstamp.net/api/balance/";


        // Create the authenticated request

        RestRequest request = new BitstampAuthenticatedRequest(baseUrl, Method.POST);


        // Get the response

        var response = new RestClient().Execute(request);
