Evernote Webhooks & Events

Overview

Implement Evernote webhook notifications for real-time change detection. Evernote webhooks notify your endpoint that changes occurred, but you must use the sync API to retrieve the actual changed data.

Prerequisites

• Evernote API key with webhook permissions
• HTTPS endpoint accessible from the internet
• Understanding of Evernote sync API

Instructions

Step 1: Webhook Endpoint

Create an Express endpoint that receives webhook POST requests. Evernote sends userId, guid (notebook GUID), and reason (create, update, notebook) as query parameters. Respond with HTTP 200 immediately, then process asynchronously.

app.post('/evernote/webhook', (req, res) => {
  const { userId, guid, reason } = req.query;
  res.sendStatus(200); // Respond immediately
