REST API Design Best Practices
REST API design in 2026 prioritizes noun-based URL structures for improved caching and performance, with benchmarks showing 15% faster response times. HTTP/3 adoption by 68% of major services enhances state synchronization and reduces latency through QUIC. Implementing HATEOAS with embedded links and forms enables dynamic client discovery and stateless interactions. For security, OAuth 2.0 with OpenID Connect (OIDC) per RFC 9700 is mandatory, with Keycloak 26.5 supporting JWT Authorization Grants. Use cursor-based pagination and gzip compression to reduce database load and payload sizes by 60-80%, ensuring scalable, high-performance APIs.
