Binance API for Google Apps Script

This sample script is for using Binance API by Google Apps Script. This script encryptes "signature" like samples. In this script, "Example 1: As a query string" is used, and it retrieves "All orders (SIGNED)" by "GET".

function main() {
    var key = '#####'; // Please input your key.
    var secret = '#####'; // Please input your secret.
    var api = "/api/v3/allOrders"; // Please input API Endpoint you want.
    var timestamp = Number(new Date().getTime()).toFixed(0);
    var string = "symbol=LTCBTC&timestamp=" + timestamp; // Please input query parameters for the inputterd API.

    var baseUrl = "https://api.binance.com";
    var signature = Utilities.computeHmacSha256Signature(string, secret);
    signature = signature.map(function(e) {
        var v = (e < 0 ? e + 256 : e).toString(16);
        return v.length == 1 ? "0" + v : v;
    }).join("");
    var query = "?" + string + "&signature=" + signature;
    var params = {
        'method': 'get',
        'headers': {'X-MBX-APIKEY': key},
        'muteHttpExceptions': true
    };
    var data = UrlFetchApp.fetch(baseUrl + api + query, params);
    Logger.log(data.getContentText())
}
