Webhook Endpoint Setup Create a publicly accessible endpoint to receive GitHub webhooks: ```typescript import express from 'express'; import { WebhookService } from './webhook-service.js'; const app = express(); app.use(express.json()); app.post('/github-webhook', async (req, res) => { const signature = req.headers['x-hub-signature-256']; const payload = JSON.stringify(req.body); // Verify webhook signature if (!webhookService.verifyWebhookSignature(payload, signature)) { return res.status(401).send('Invalid signature'); } // Process the event try { await webhookService.processWebhookEvent(req.body); res.status(200).send('OK'); } catch (error) { res.status(500).send('Processing failed'); } }); app.listen(3000, () => { console.log('Webhook server running on port 3000'); }); ``` ### 3. Configure Webhooks ``` setup_webhooks { "webhook_url": "https://your-server.com/github-webhook", "events": ["issues", "milestone", "pull_request"], "secret": "your-webhook-secret" } ``` ### 4.
