    username: admin # RouterOS user with API access
    password: "" # RouterOS user password
  ip_service:
    - ifconfig.me # External service to get IP address
# If you use IP routing rules for specific traffic, ensure the domain used by ip_service is excluded.

updaters:
  cloudflare:
    email: "[email protected]" # Cloudflare account email
    apikey: fd25bdc03a4c17450aa4327aa37de4573270f # Cloudflare API key
    domain: ddns.yourdomain.com # Domain to update
  # lightdns: # Use LightDNS as the updater
  #   key: bgw99xiio5ewbphb
  #   domain: uddns.dyn.la
notifiers:
  telegram:
    chat_id: -1001234567890 # Telegram chat ID
