You can generate API-keys in you account settings.

For each request you will need API-Signature:

  1. Calculate signatureText = publicKey + requestUrl + requestBodyString (no separator symbols in-between)
  • publicKey - example: b2H9TlfRu6MOgG4m9wvrf9maSUiPsQJEui0JrB
  • requestUrl - full url of request, example: https://data./api/orders
  • requestBodyString - json request body as a 1-line string, example: {"isBid":true,"currencyPairCode":"ETH_BTC","amount":0.01,"price":0.02}. For GET methods it will be an empty string.
  • signatureText = b2H9TlfRu6MOgG4m9wvrf9maSUiPsQJEui0JrBhttps://data./api/orders{"isBid":true,"currencyPairCode":"ETH_BTC","amount":0.01,"price":0.02}
  • signatureText for GET method = b2H9TlfRu6MOgG4m9wvrf9maSUiPsQJEui0JrBhttps://data./api/orders
  1. Convert signatureText as UTF8-string to bytes

  2. Compute HMACSHA256 hash from signatureText-bytes

  3. Convert hash-bytes to HEX-string

Example in JS code:

 <script src=""></script>

let signature = CryptoJS.enc.Hex.stringify(CryptoJS.HmacSHA256(publicKey + requestUrl + requestBodyString, privateKey));

Example in C# code:

 string signature = new HMACSHA256(Encoding.UTF8.GetBytes(privateKey))
.ComputeHash(Encoding.UTF8.GetBytes(publicKey + requestUrl + requestBodyString))
.Aggregate(new StringBuilder(), (sb, b) => sb.AppendFormat("{0:x2}", b), (sb) => sb.ToString());

API-Signature should look like this: b7238692e0537d3a7fd13faff266d315e3185247e1644c1155f60e6d4e4e445d
