To design a production-grade API, you must standardize URL structures, HTTP methods, and status codes. This process ensures your RESTful endpoints feature robust pagination, consistent error response formats, and safe evolution without accumulating technical debt.

Choosing between GraphQL, REST, and gRPC depends on your specific data fetching and communication needs. API style selection evaluates whether you need flexible client-driven queries (GraphQL), standardized resource manipulation (REST), or high-performance binary streaming (gRPC).

Best practices for API versioning and rate limiting involve implementing robust strategies within your API design to protect services and manage evolution. Proper versioning prevents breaking changes, while rate limiting controls traffic flow and ensures fair resource usage among consumers.

Generating OpenAPI documentation requires defining a clear API contract that details your endpoints, request/response schemas, and security protocols. Using a dedicated API design approach ensures your microservice documentation is standardized, consistent, and safe to evolve.

API design supports both idempotency and WebSocket connections. It covers idempotency to prevent duplicate processing of repeated requests and includes WebSocket/SSE style selection to handle real-time, bidirectional data streaming within your service architecture.
