The code

function SignatureTest() {
  var key = 'Key';
  var secret = 'Secret Key';

  var curTime = Number(new Date().getTime()).toFixed(0);
  var string = "symbol=LTCBTC&timestamp=" + curTime;
  var sKey = Utilities.computeHmacSha256Signature(string, secret);
  sKey = sKey.map(function(e) {
      var v = (e < 0 ? e + 256 : e).toString(16);
      return v.length == 1 ? "0" + v : v;
  }).join("");
  var params = {
    'method': 'get',
    'headers': {'X-MBX-APIKEY': key},
    'muteHttpExceptions': true
  };
  var url = "https://api.binance.com/api/v3/allOrders?" + string + "&signature=" + sKey;
  var data = UrlFetchApp.fetch(url, params);
  Logger.log(data.getContentText())
}
