# Windsurf Webhooks & Events

## Overview
Securely handle Windsurf webhooks with signature validation and replay protection.

## Prerequisites
- Windsurf webhook secret configured
- HTTPS endpoint accessible from internet
- Understanding of cryptographic signatures
- Redis or database for idempotency (optional)

## Webhook Endpoint Setup

### Express.js
```typescript
import express from 'express';
import crypto from 'crypto';

const app = express();

// IMPORTANT: Raw body needed for signature verification
app.post('/webhooks/windsurf',
  express.raw({ type: 'application/json' }),
  async (req, res) => {
    const signature = req.headers['x-windsurf-signature'] as string;
    const timestamp = req.headers['x-windsurf-timestamp'] as string;

    if (!verifyWindsurfSignature(req.body, signature, timestamp)) {
      return res.status(401).json({ error: 'Invalid signature' });
    }

    const event = JSON.parse(req.body.toString());
    await handleWindsurfEvent(event);

    res.status(200).json({ received: true });
  }
);
```

## Signature Verification

```typescript
function verifyWindsurfSignature(
  payload: Buffer,
  signature: string,
  timestamp: string
): boolean {
  const secret = process.env.WINDSURF_WEBHOOK_SECRET!;

  // Reject old timestamps (replay attack protection)
  const timestampAge = Date.now() - parseInt(timestamp) * 1000;
  if (timestampAge > 300000) { // 5 minutes
    console.error('Webhook timestamp too old');
    return false;
  }

  // Compute expected signature
  const signedPayload = `${timestamp}.${payload.toString()}`;
  const expectedSignature = crypto
    .createHmac('sha256', secret)
    .update(signedPayload)
    .digest('hex');

  // Timing-safe comparison
  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expectedSignature)
  );
}
```

## Event Handler Pattern

```typescript
type WindsurfEventType = 'resource.created' | 'resource.updated' | 'resource.deleted';

interface WindsurfEvent {
  id: string;
  type: WindsurfEventType;
  data: Record<string, any>;
  created: string;
}

const eventHandlers: Record<WindsurfEventType, (data: any) => Promise<void>> = {
  'resource.created': async (data) => { /* handle */ },
  'resource.updated': async (data) => { /* handle */ },
  'resource.deleted': async (data) => { /* handle */ }
};

async function handleWindsurfEvent(event: WindsurfEvent): Promise<void> {
  const handler = eventHandlers[event.type];

  if (!handler) {
    console.log(`Unhandled event type: ${event.type}`);
    return;
  }

  try {
    await handler(event.data);
    console.log(`Processed ${event.type}: ${event.id}`);
  } catch (error) {
    console.error(`Failed to process ${event.type}: ${event.id}`, error);
    throw error; // Rethrow to trigger retry
  }
}
```

## Idempotency Handling

```typescript
import { Redis } from 'ioredis';

const redis = new Redis(process.env.REDIS_URL);

async function isEventProcessed(eventId: string): Promise<boolean> {
  const key = `windsurf:event:${eventId}`;
  const exists = await redis.exists(key);
  return exists === 1;
}

async function markEventProcessed(eventId: string): Promise<void> {
  const key = `windsurf:event:${eventId}`;
  await redis.set(key, '1', 'EX', 86400 * 7); // 7 days TTL
}
```

## Webhook Testing

```bash
# Use Windsurf CLI to send test events
windsurf webhooks trigger resource.created --url http://localhost:3000/webhooks/windsurf

# Or use webhook.site for debugging
curl -X POST https://webhook.site/your-uuid \
  -H "Content-Type: application/json" \
  -d '{"type": "resource.created", "data": {}}'
```

## Instructions

### Step 1: Register Webhook Endpoint
Configure your webhook URL in the Windsurf dashboard.

### Step 2: Implement Signature Verification
Use the signature verification code to validate incoming webhooks.

### Step 3: Handle Events
Implement handlers for each event type your application needs.

### Step 4: Add Idempotency
Prevent duplicate processing with event ID tracking.

## Output
- Secure webhook endpoint
- Signature validation enabled
- Event handlers implemented
- Replay attack protection active

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Invalid signature | Wrong secret | Verify webhook secret |
| Timestamp rejected | Clock drift | Check server time sync |
| Duplicate events | Missing idempotency | Implement event ID tracking |
| Handler timeout | Slow processing | Use async queue |

## Examples

### Testing Webhooks Locally
```bash
# Use ngrok to expose local server
ngrok http 3000

# Send test webhook
curl -X POST https://your-ngrok-url/webhooks/windsurf \
  -H "Content-Type: application/json" \
  -d '{"type": "test", "data": {}}'
```
