Cloudflare DNS API
Cloudflare's REST API for managing DNS records, zones, page rules, firewall rules, and other Cloudflare services programmatically across managed domains.
Best When
Your DNS is managed through Cloudflare and you need to automate record management, DDNS, or DNS-based workflows.
Avoid When
Your domain is on a different DNS provider, or you need domain registration features.
Use Cases
- • Dynamic DNS (DDNS) updates for home servers or dynamic IPs
- • Automated DNS record management in CI/CD deployments
- • Managing DNS as code across multiple domains and zones
- • Programmatic certificate and TLS configuration
- • Automating Let's Encrypt DNS challenge records for wildcard certs
Not For
- • Domain registration (use Cloudflare Registrar or Namecheap/GoDaddy)
- • DNS resolution queries (use the DNS resolver, not management API)
- • Domains not managed through Cloudflare
