Getting Started

Create a new Coinbase account.

Head to the API section in the Settings and create an API Key.

Choose the appropriate API permissions as listed

here

After successfully creating the app, you will be presented with your API_KEY and API_SECRET. Keep them handy.

Make API Request

const createCBRequest = (method, url) => {
  var timeInSeconds = parseInt(new Date().getTime() / 1000);
  var sigString = timeInSeconds + `${method}${url}`;

  var hmac = crypto.createHmac("sha256", API_SECRET);
  signature = hmac.update(sigString).digest("hex");

  const config = {
    method,
    url: `https://api.coinbase.com${url}`,
    headers: {
      "CB-ACCESS-KEY": API_KEY,
      "CB-ACCESS-SIGN": signature,
      "CB-ACCESS-TIMESTAMP": timeInSeconds,
    },
  };

  return axios(config);
};

Get User Details

app.get("/user", async (req, res) => {
  try {
    const response = await createCBRequest("GET", "/v2/user");
    res.send({ response: response?.data });
  } catch (e) {
    console.log("Could not get user", e.response.data);
  }
});

Get Primary Account

app.get("/account", async (req, res) => {
  try {
    const response = await createCBRequest("GET", "/v2/accounts/BTC");
    res.send({ response: response?.data });
  } catch (e) {
    console.log("Could not get account", e.response.data);
  }
});
