mtGox Trading API down? [solved]

[NYConsultant]

You guys do realize that you need to issue a POST to that url with your credentials as POST'ed variables?  Hitting it from the browser with your credentials as query string parameters will always yield that error message.

If you need some C# code to illustrate this, let me know; i've written a c# api that will talk to the MTGox api for you

I'd like to see you C# code as I am still stuck at the error must log in stage...

Would you post it here?

Otherwise, feel free to email me the cs file. I am using gmail with the same username.

Still interested in you version of the API. But at least I got the basics working:


For all the C# devs around here: This is the basic code to use the API as of today.

        public static string GetBalance(string userName, string password)
        {
            // parameters: name1=value1&name2=value2
            var parameters = "name=" + HttpUtility.UrlEncode(userName)
                 + "&pass=" + HttpUtility.UrlEncode(password);

            var req = (HttpWebRequest) WebRequest.Create("https://mtgox.com/code/getFunds.php");

            req.ContentType = "application/x-www-form-urlencoded";
            req.Method = "POST";
            req.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)";
            req.Accept = "application/json";

            byte[] bytes = Encoding.ASCII.GetBytes(parameters);
            req.ContentLength = bytes.Length;

            Stream os = req.GetRequestStream();
            os.Write(bytes, 0, bytes.Length);
            os.Close();

            WebResponse resp = req.GetResponse();

            try
            {
                var sr = new StreamReader(resp.GetResponseStream());
                return sr.ReadToEnd().Trim();
            }
            catch (Exception ex)
            {
                Logger.Fatal(ex.Message);
                Logger.FatalException(ex.InnerException.ToString(), ex);   
                return null;
            }
        } // end HttpPost


What got me stuck in the very beginning was that I lacked the UserAgent. This lead to TimeOuts without any (for me obvious) reason. After that I was having some issues with the combination of Url/HtmlEncode and the ContentType...

Any feedback appreciated.

PS:
As this may become out of date pretty much any moment, also look out for comments by "SlipperySlope" on how to do it in Java. The only change you have to make is that whenever we writes that he is using HtmlEncoding, in C# the UrlEncoding is needed.

PPS: Now I know why I need UrlEncode instead of HtmlEncode: it is the ContentType header

PPPS: Yes, this is some kind of x-post to the thread http://forum.bitcoin.org/index.php?topic=25644

I get:

{"error":"Bad token"}

Regards,

oooo I think I figured out what the problem is.  You have to submit a token variable.  It is given in the html when you log in.

Code:

<script type="text/javascript" language="javascript">
var token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

</script>

so to get the order data, you do this:

1) login
2) in the trade HTML, it will give you a token value (see above).
3) HTTP POST https://mtgox.com/code/getOrders.php

No need to get token or cookie:


        public static string GetOpenOrders(string userName, string password)
        {
            // parameters: name1=value1&name2=value2
            var parameters = "name=" + HttpUtility.UrlEncode(userName)
                 + "&pass=" + HttpUtility.UrlEncode(password);

            var req = (HttpWebRequest)WebRequest.Create("https://mtgox.com/code/getOrders.php");

            req.ContentType = "application/x-www-form-urlencoded";
            req.Method = "POST";
            req.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)";
            //req.Accept = "application/json";

            byte[] bytes = Encoding.ASCII.GetBytes(parameters);
            req.ContentLength = bytes.Length;

            Stream os = req.GetRequestStream();
            os.Write(bytes, 0, bytes.Length);
            os.Close();

            WebResponse resp = req.GetResponse();

            try
            {
                var sr = new StreamReader(resp.GetResponseStream());
                return sr.ReadToEnd().Trim();
            }
            catch (Exception ex)
            {
                Logger.Fatal(ex.Message);
                Logger.FatalException(ex.InnerException.ToString(), ex);   
                return null;
            }
        } // end HttpPost
