API EXMO, new rules?

Question

PHP

Hello! The devils
from exmo, as they usually bring gifts, this time, touched on a non-public
API .

curl -X POST \
https://api.exmo.com/v1/order_create/ \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Key: K-xxx' \
-H 'Sign: xxx' \
-d 'nonce=100500&pair=BTC_USD&type=buy&quantity=0.01&price=5000'

The code used to work

function api_query($api_name = "excode_load", array $req = array())
{
    $mt = explode(' ', microtime());
    $NONCE = $mt[1] . substr($mt[0], 2, 6);

    // API settings
    $key = "K-"; //TODO replace with your api key from profile page
    $secret = "S-"; //TODO replace with your api secret from profile page

    $excode = ""; 

    $url = "http://api.exmo.com/v1/$api_name?code=$excode";

    $req['nonce'] = $NONCE;

    // 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($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; PHP client; ' . php_uname('s') . '; PHP/' . phpversion() . ')');
    }
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($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 === null)
        throw new Exception('Invalid data received, please make sure connection is working and requested API exists');

    return $dec;
}

How can I make it fit their rules?

вместо

$url = "http://api.exmo.com/v1/$api_name?code=$excode";

$req['nonce'] = $NONCE;

сделайте

$url = "http://api.exmo.com/v1/$api_name/";

$req['nonce'] = $NONCE;
$req['code'] = $excode;

и добавьте в заголовки

$headers = array(
    'Content-Type: application/x-www-form-urlencoded',
    'Sign: ' . $sign,
    'Key: ' . $key,
);
