Konfigurasi Webhook

# Install ngrok
brew install ngrok  # macOS
# atau download dari https://ngrok.com

# Jalankan server lokal Anda
node server.js  # Aplikasi Anda mendengarkan di port 3000

# Buat tunnel
ngrok http 3000

# Anda akan mendapatkan URL seperti: https://abc123.ngrok.io

curl -X POST https://your-webhook-url.com/webhook \
  -H "Authorization: your_secret_key" \
  -H "Content-Type: application/json" \
  -d '{
    "event": "channel.message_in",
    "timestamp": 1738056000,

✅ Bagus:
https://api.yourdomain.com/webhooks/csku
https://api.yourdomain.com/v1/webhooks
https://webhooks.yourdomain.com/ai

❌ Hindari:
https://api.yourdomain.com (endpoint root)
https://api.yourdomain.com/a/b/c/d/e (terlalu bersarang)

# Tambahkan subdomain webhook
webhooks.yourdomain.com IN A 192.0.2.1

# Atau gunakan domain API yang ada
api.yourdomain.com IN A 192.0.2.1

# Periksa sertifikat SSL
curl -I https://your-webhook-url.com/webhook

# Seharusnya menampilkan:
# SSL certificate verify ok.

# Contoh aturan firewall (sesuaikan dengan setup Anda)
ufw allow 443/tcp  # HTTPS
ufw allow 80/tcp   # HTTP (pengujian saja)

# Contoh konfigurasi nginx
