# Evernote Webhooks & Events

## Overview
Implement Evernote webhook notifications for real-time change detection. Note: Evernote webhooks notify you that changes occurred, but you must use the sync API to retrieve actual changes.

## Prerequisites
- Evernote API key with webhook permissions
- HTTPS endpoint accessible from internet
- Understanding of Evernote sync API

## Instructions

### Step 1: Webhook Endpoint

### Step 2: Webhook Reasons

### Step 3: Sync State Management

### Step 4: Webhook Event Processing

### Step 5: Event Handlers

### Step 6: Webhook Registration

### Step 7: Polling Fallback

For full implementation details and code examples, load:
`references/implementation-guide.md`

## Output
- Webhook endpoint implementation
- Sync state management
- Event-driven change processing
- Event handlers for note lifecycle
- Polling fallback mechanism

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Webhook not received | URL not reachable | Verify HTTPS endpoint |
| Duplicate webhooks | Network retries | Implement idempotency |
| Missing changes | Race condition | Re-sync after timeout |
| Sync timeout | Large change set | Increase chunk size |
