NodeJs example code for Bitfinex API v1 Authenticated call

bitfinex-node.js

var https = require('https');
var crypto = require('crypto');

var url = 'https://bitfinex.com/api/v1/balances';
var subPath = '/balances';

var api_key = '';
var api_secret = '';

var path = '/api/v1' + subPath;
console.log(path);

var payloadObject = {
  request : path,
	nonce : "" + Date.now(),
	options : {}
};

var payloadJson = JSON.stringify(payloadObject);

console.log(JSON.stringify(payloadObject));

var payload = new Buffer(payloadJson).toString('base64');

console.log(payload);

var signature = crypto.createHmac('sha384', api_secret).update(payload).digest('hex');

var headers = {
	"X-BFX-APIKEY" : api_key,
	"X-BFX-PAYLOAD" : payload,
	"X-BFX-SIGNATURE" : signature
};

console.log(headers);

var options = {
	hostname : 'bitfinex.com',
	port : 443,
	path : '/api/v1/balances',
	method : 'GET',
	headers: headers
};

var req = https.request(options, function(res) {
	console.log("statusCode: ", res.statusCode);
	console.log("headers: ", res.headers);

	res.on('data', function(d) {
		process.stdout.write(d);
	});
});
req.end();

req.on('error', function(e) {
	console.error(e);
});
