Bittrex API returns APIKEY_NOT_PROVIDED

Question

Bittrex API returns APIKEY_NOT_PROVIDED

I am trying to call the Bittrex api in my sample iOS app.

I got the following message.

Return message

SUCCESS: {
    message = "APIKEY_NOT_PROVIDED";
    result = "<null>";
    success = 0;
}

And I checked the HTTP request, apikey was included below.

API request

$ curl -i \
    -b "__cfduid=dea9a55b977dded0f94ad14f7158f03e91497078592" \
    -H "Content-Type: application/json" \
    -H "Accept-Language: en;q=1.0" \
    -H "apisign: 41a5b3a98d7da9bee01ddb8ab72dee...." \
    -H "User-Agent: SampleApp/1.0 (com.sampleapp.SampleApp; build:1; iOS 10.3.1) Alamofire/4.4.0" \
    -H "Accept-Encoding: gzip;q=1.0, compress;q=0.5" \
    -d "{\"apikey\":\"f23439b...\",\"nonce\":\"1497703898.0\"}" \
"https://bittrex.com/api/v1.1/account/getbalances"

And my code is like the following.

code

let timeInterval = NSDate().timeIntervalSince1970
let epochtime = String(floor(timeInterval))
let parameters = "apikey=" + "f23439b..." + "&" + "nonce=" + epochtime
let url = path + "getbalances" + "?" + parameters
let secretKey: String = "df8a62...".hmac(algorithm: CryptoAlgorithm.SHA512, key: url)

Alamofire.request(path + "getbalances", 
                  method: .get, 
                  parameters: ["apikey":"f23439b...", "nonce":epochtime], 
                  encoding: JSONEncoding.default, 
                  headers: ["apisign":secretKey])
    .responseJSON(completionHandler: { response in
        let json = response.result.value as! NSDictionary
        let success = json["success"] as! CFBoolean
        if (success == kCFBooleanTrue) {
            //do something
            print(json)
        } else {
            let reason = response.result.description as AnyObject
            print(reason)
        }
    })

Environment

macOS Sierra
XCode 8.3.3
Swift 3
Alamofire 4.4

I believe you have a problem with the new V1.1 API where you need to encrypt the secret using HMAC-SHA512:

For this version, we are using the standard HMAC-SHA512 signature. Add apikey

both nonce

to your request and compute the HMAC hash and include it under the header apisign

. Note: the nonce is not enforced right now but will be applied later.

Not an iOS expert, but this might help you:

$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);

looks like a simple typo / you should use api secret and a string that assumes what i believe should be a uri (not url). There is a fast BittrexKit library using the Crypro library - with a slightly different method signature.

let secretKey: String = URI.hmac(algorithm: CryptoAlgorithm.SHA512, key: APISECRET)

cherry picked from https://github.com/yuzushioh/BittrexKit

import Crypto

    guard let sign = HMAC.sign(message: uri, algorithm: .sha512, key: auth.apiSecret) else {
        print("Bittrex: HMAC failed")
    }



  private func buildURI() -> String? {
    let url = path.isEmpty ? baseURL : baseURL.appendingPathComponent(path)

    guard var components = URLComponents(url: url, resolvingAgainstBaseURL: true) else {
        return nil
    }

    if let queryParameters = queryParameters, !queryParameters.isEmpty {
        components.percentEncodedQuery = URLEncodedSerialization.string(from: queryParameters)
    }

    guard let uri = components.url?.absoluteString else {
        return nil
    }

    return uri
  }

(if anyone gets this working with alamofire - any changes are welcome.)
