[b]Ok [h]so… I’m programming API connected xojo apps for trading bitcoin… essentially.[/h]
Bittrex.com was no problem… because Christian was kind enough to explain exactly what I needed to do… And for the most part I understood it. Well I’ve moved on from bittrex.com to cryptsy.com and cryptsy is slightly more advanced style API connectivity…
Here’s Bittrex PHP API example[/b]
$apikey='xxx';
$apisecret='xxx';
$nonce=time();
$uri='https://bittrex.com/api/v1.1/market/getopenorders?apikey='.$apikey.'&nonce='.$nonce;
$sign=hash_hmac('sha512',$uri,$apisecret);
$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);
Here’s my code for Bittrex API written in XOJO (Working!)
[code] dim apikey as string = bittrexApiKey
dim apisecret as string = bittrexApiSecret
dim nonceDate as date
nonceDate = new date
dim nonce as string = str(nonceDate.TotalSeconds)
dim uri as string = query + apikey + otherData + "&nonce=" + nonce
dim uriMemBlock as MemoryBlock = uri
dim sign as string = EncodeHex(Crypto.HMAC(apiSecret, uriMemBlock, Crypto.Algorithm.SHA512), false)
dim c as new CURLSMBS
c.OptionURL = uri
c.SetOptionHTTPheader array("apisign:" + sign)
c.OptionVerbose = true
c.CollectDebugData = true
c.CollectOutputData = true
c.OptionSSLVerifyHost = 0
c.OptionSSLVerifyPeer = 0
dim e as integer = c.Perform
dim data as string = c.OutputData
return c.OutputData[/code]
Here’s Cryptsy PHP API example
[code]<?php
function api_query($method, array $req = array()) {
// API settings
$key = ‘’; // your API-key
$secret = ‘’; // your Secret-key
$req['method'] = $method;
$mt = explode(' ', microtime());
$req['nonce'] = $mt[1];
// generate the POST data string
$post_data = http_build_query($req, '', '&');
$sign = hash_hmac("sha512", $post_data, $secret);
// generate the extra headers
$headers = array(
'Sign: '.$sign,
'Key: '.$key,
);
// our curl handle (initialize if required)
static $ch = null;
if (is_null($ch)) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; Cryptsy API PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
}
curl_setopt($ch, CURLOPT_URL, 'https://api.cryptsy.com/api');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
// run the query
$res = curl_exec($ch);
if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
$dec = json_decode($res, true);
if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
return $dec;
}[/code]
Here’s my code… which I haven’t even tested yet cause I don’t understand $req = array() and I don’t understand the $post_data = http_build_query($req, ‘’, ‘&’); either…
dim apikey as string = "29d843337f62fafae60FAKEKEY170a8a64e"
dim apisecret as string = "616ef523d1606208041eFAKEKEY75703585b6c82bbf11713fbb470c722b116e4177fbeb29ad0"
dim nonceDate as date
nonceDate = new date
dim nonce as string = str(nonceDate.TotalSeconds)
dim uri as string = query + otherData + "&nonce=" + nonce
dim uriMemBlock as MemoryBlock = uri
dim sign as string = EncodeHex(Crypto.HMAC(apiSecret, uriMemBlock, Crypto.Algorithm.SHA512), false)
dim c as new CURLSMBS
c.OptionURL = uri
c.OptionPostFields =
c.SetOptionHTTPheader array("Sign: " + sign, "Key: " + apiKey)
c.OptionVerbose = true
c.CollectDebugData = true
c.CollectOutputData = true
c.OptionSSLVerifyHost = 0
c.OptionSSLVerifyPeer = 0
dim e as integer = c.Perform
dim data as string = c.OutputData
return c.OutputDataIf I could just understand those 2 things… I could probably get this working! Any help is awesome.
