Verifying a webhook signature with the Nylas Node.js SDK

const Nylas = require("nylas");
const express = require("express");
const cors = require("cors");


const app = express();


// Enable CORS
app.use(cors());


// The port the express app will run on
const port = 9000;


// Nylas app credentials
const NYLAS_CLIENT_SECRET = process.env.NYLAS_CLIENT_SECRET;
if (!NYLAS_CLIENT_SECRET) {
  throw new Error("NYLAS_CLIENT_SECRET is required");
}


// Create a callback route for the Nylas Event Webhook
app.post("/", express.json(), async (req, res) => {
  // Verify the Nylas Event Webhook signature to ensure the request is coming from Nylas
  const signature =
    req.headers["x-nylas-signature"] || req.headers["X-Nylas-Signature"];
  if (
    !WebhookNotification.verifyWebhookSignature(
      NYLAS_CLIENT_SECRET,
      signature,
      JSON.stringify(req.body)
    )
  ) {
    res.status(403).send("Invalid signature");
  }


  const { body } = req;


  // Log the webhook event to the console
  console.log("Webhook event received: ", JSON.stringify(body, undefined, 2));


  // Send a 200 response to the Nylas Event Webhook
  res.status(200).send({ success: true });
});
