Auth

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

2. Convert signatureText as UTF8-string to bytes

3. Compute HMACSHA256 hash from signatureText-bytes

4. Convert hash-bytes to HEX-string

Example in JS code:

 <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.min.js"></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
