Authenticated API Calls

You will need to create an API secret key in order to make authenticated API calls. Here's an example of how to do that:

const crypto = require("crypto");
const apiKey = "[YOUR_API_KEY]";
const apiSecret = "[YOUR_API_SECRET]";

const getNonce = () => Math.round(new Date().getTime() / 1000);
const createSignature = (nonce) => {
  const rawSignature = `AUTH${nonce}`;
  return crypto.createHmac("sha384", apiSecret).update(rawSignature).digest("hex");
};
const getHeaders = (url) => {
  const nonce = getNonce();
  const signature = createSignature(nonce);
  return {
    "X-BFX-APIKEY": apiKey,
    "X-BFX-PAYLOAD": new Buffer('{"request":"/v1' + url + '","nonce":"' + nonce + '"}').toString('base64'),
    "X-BFX-SIGNATURE": signature,
  };
};

Get Account Balance

const url = "/balances";
const headers = getHeaders(url);

fetch(`https://api.bitfinex.com/v1${url}`, { headers })
  .then(response => response.json())
  .then(data => console.log(data));

Place an Order

const url = "/order/new";
const symbol = "btcusd";
const amount = 1;
const price = 60000;
const side = "buy";
const type = "exchange limit";

const payload = JSON.stringify({
  symbol,
  amount,
  price,
  side,
  type,
});

const headers = getHeaders(url);

fetch(`https://api.bitfinex.com/v1${url}`, { body: payload, headers, method: "POST" })
  .then(response => response.json())
  .then(data => console.log(data));
