    post data: clientOrderId=11111112&symbol=BTCUSD&side=buy&pric e=0.1&quantity=100&type=limit&timeInForce=GTC


    php example; https://gist.github.com/hitbtc-com/10885873
    sorce
    Code:
     using RestSharp;
    using System;
    using System.Linq;
    using System.Security.Cryptography;
    using System.Text;
    
    
    
    
    namespace Hitbtc.Api.Demo
    {
        class Program
        {
            static void Main(string[] args)
            {
                const string apiKey = "xxx";
                const string secretKey = "yyy";
                var client = new RestClient("https://api.hitbtc.com");
    
    
                var VARrequest = new RestRequest("/api/1/trading/new_order", Method.POST);
                VARrequest.AddParameter("nonce", GetNonce());
                VARrequest.AddParameter("apikey", apiKey);
                string sign = CalculateSignature(client.BuildUri(VARrequest).PathAndQuery, secretKey);
                VARrequest.AddHeader("X-Signature", sign);
                VARrequest.RequestFormat = DataFormat.Json;
                VARrequest.AddBody(new
                {
                  clientOrderId = "58f32654-723a-4b60-ad6b",
                  symbol = "BTCUSD",
                  side = "buy",
                  quantity = "0.01",
                  type = "limit" ,
                  price = "788.56",
                  timeInForce = "GTC" });
               
                var VARresponse = client.Execute(VARrequest);
    
    
                Console.WriteLine(VARresponse.Content);
                System.Threading.Thread.Sleep(5000);
            }
    
    
    
    
            private static long GetNonce()
            {
                return DateTime.Now.Ticks * 10 / TimeSpan.TicksPerMillisecond; // use millisecond timestamp or whatever you want
            }
    
    
            public static string CalculateSignature(string text, string secretKey)
            {
                using (var hmacsha512 = new HMACSHA512(Encoding.UTF8.GetBytes(secretKey)))
                {
                    hmacsha512.ComputeHash(Encoding.UTF8.GetBytes(text));
                    return string.Concat(hmacsha512.Hash.Select(b => b.ToString("x2")).ToArray()); // minimalistic hex-encoding and lower case
                }
            }
        }
    }

    This is C#, I presume?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    It looks like you have a space or some other non-printable character in your api key...
    If you understand what you're doing, you're not learning anything.
