I am trying to connect to Cryptopia API to get my balance in Google Sheet and I can't make it work. The error I am currently getting is:
Signature does not match request parameters
My code:
var key1 = "API_KEY";
var secret1 = "API_SECRET";
var nonce = Math.floor(new Date().getTime()/1000);
var params = {"Currency" : "BTC"};
var url = 'https://www.cryptopia.co.nz/api/GetBalance';
var requestContentBase64String = Utilities.base64Encode(Utilities.computeDigest(Utilities.DigestAlgorithm.MD5, JSON.stringify(params), Utilities.Charset.UTF_8)); // Added
var signature = key1 + "POST" + encodeURIComponent(url).toLowerCase() + nonce + requestContentBase64String; // Modified
var hmacsignature = Utilities.base64Encode(Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_256, signature, Utilities.base64Decode(secret1), Utilities.Charset.UTF_8)); // Modified
var header_value = "amx " + key1 + ":" + hmacsignature + ":" + nonce;
var headers = {
"Authorization": header_value,
"Content-Type": 'application/json; charset=utf-8'
//"Content-Length" : Utilities.newBlob(JSON.stringify(params)).getBytes().length // Added
};
var options = {
"method": 'POST',
"headers": headers,
"payload": JSON.stringify(params),
"contentLength": JSON.stringify(params).length
};
var response = UrlFetchApp.fetch(url, options);
Logger.log(response)
return JSON.parse(response.getContentText());
There is one more thread regarding the same issue on stackoverflow but without correct answer.
Thank you
