Just change line #6 command from "returnBalances" to "returnOpenOrders" and add an optional parameter after it and before nonce, "¤cyPair=BTC_XCP".
It should work. I don't have a poloniex account anymore to test it.

it works. thanks

can you please put the code for call the command "returnOpenOrders"?

"Returns your open orders for a given market, specified by the "currencyPair" POST parameter, e.g. "BTC_XCP". Set "currencyPair" to "all" to return open orders for all markets. Sample output for single market:"

Thanks in advance

I'll add my thanks. This helped set up CB/GDAX api access as well.

Coding Enthusiast,
I registered on this site only so I could say thank you for posting this!
Dang, I would have been stuck for days on this, so thanks a big bunch to you!

Now I can proceed in automatically losing my altcoins instead of having to throw them away manually! =)

Best regards
Luser

PS. Thanks to Amonra75 too for asking, of course. The web is truly awesome at times!

Thanks for sharing that link - you saved me a lot of time getting the signature generated, first API I tried since Cryptsy - seems line every API has its quirks.

i write the complete code

Code:

private readonly string _apiKey = "N68R67PJ-BZ89CNWB-O2UOOH59-YYFSX9MB"; // Random numbers and letters
private readonly string _apiSecret = "345eaefc0bf5fbb5a048de7f8dc728646b61249f9c8fd9c1a99319e3ed0d55a6b8e43702cea379b2d136fe9b877f132706ceebc2930b220322b23a207151ea78";
private long nonce = DateTime.Now.Ticks;

private string CreateSignature()
{
//string msg = string.Format("{0}{1}{2}", _apiKey);

return ByteArrayToString(SignHMACSHA512(_apiSecret, StringToByteArray(_apiKey))).ToUpper();
}

private static byte[] SignHMACSHA512(String key, byte[] data)
{
HMACSHA512 hashMaker = new HMACSHA512(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) //rimuove - e converte in bite
{
return BitConverter.ToString(hash).Replace("-", "").ToLower();
}

private void button5_Click(object sender, EventArgs e)
{

const string WEBSERVICE_URL = "https://poloniex.com/tradingApi";
try
{

var webRequest = System.Net.WebRequest.Create(WEBSERVICE_URL);
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.Timeout = 12000;
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Headers.Add("Key", _apiKey);
webRequest.Headers.Add("Sign", CreateSignature()); // keysecret

var postData = "&nonce=&command=returnBalances";
var data = Encoding.ASCII.GetBytes(postData);

using (System.IO.Stream s = webRequest.GetResponse().GetResponseStream())
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(s))
{
var jsonResponse = sr.ReadToEnd();
Console.WriteLine(String.Format("Response: {0}", jsonResponse));
}
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}

i have remove the extra headers but see the error

this header is extra

Code:

webRequest.Headers.Add("command", "returnDepositAddresses");

i have WebRequest class Cheesy

you should put the "command" and "returnDepositAddresses" in httpcontent and sign that, then add the signature to the header "sign"
i have no idea what you are doing here:

Code:

webRequest.Headers.Add("Sign", CreateSignature());

what does that function sign without having any input variable?

PHP is the closest example you can see and kind of understand when using c# IMO: http://pastebin.com/iuezwGRZ (see line 28 and 29)
