BITTREX API + WAMP Server

[DogWelder]

Hi all,

I've been trying to use the Bittrex API on WampServer 3.0.6 x64 (default setting).
I'm using the default example from the Bittrex API page (https://bittrex.com/Home/Api) but I'm not getting any results (simple php commands work however).

$apikey='blahblahmykey';
$apisecret='blahblahmysecret';
$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);

Can anyone suggest a possible solution or an alternative webserver with which they've had success? Thanks in advance.

Do you have the json and curl PHP extensions installed?

Do you have the json and curl PHP extensions installed?

Hi! Yes, curl is running (uncommented in php.ini, also ran a simple function to check if enabled). From what I see, the variable $execResult is returned empty.
I have been deleting and making new API keys/secrets in the hopes that there lies the problem, but nothing seems to change.

Maybe the problem lies on the fact that it's an https request? It's possible curl doesn't trust the server certificate. Add error_reporting(E_ALL); at the start of the script to see what the error is.

Error reporting didn't show anything, but after googling a bit, I found this page: http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/.
I used the quick fix (for now) by adding the line:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
Many thanks for your help!

That's what I told you regarding curl not trusting the server. However I'd be wary of doing so since it makes your script/site open to MITM attacks (intercepting the request to bittrex.com)

[DogWelder]

Of course, what I meant is that I googled about curl and the server certificates just like you suggested, and found the answer. I'll implement the secure solution as soon as I've finalized the script.
Many thanks again!

Hey guys

I was having the same problem, tried to fix it with curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Now I'm getting Error 404: We can't seem to find what you're looking for, here's a screenshot:

Here's my code (I'm using WAMP and 7.1.9 php version):

Code:

<?php
$apikey='myKey';
$apisecret='mySecret';
$nonce=time();
$uri='https://bittrex.com/api/v1.1/market/getbalances?apikey='.$apikey.'&nonce='.$nonce;
$sign=hash_hmac('sha512',$uri,$apisecret);

$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);
?>

Any ideas what might be wrong?
Thanks
