To design a REST API, follow industry best practices for resource naming, use appropriate HTTP methods, standard status codes, and consistent request/response formats. This ensures your API endpoints are robust, maintainable, and intuitive for developers to consume.

Generating OpenAPI 3.0 specifications involves documenting your REST API structure, including endpoints, request/response formats, and authentication methods. This creates a clear API contract that enforces consistency and maintainability before you write any backend code.

GraphQL offers a schema-based alternative to REST API design, allowing clients to request specific data fields. While REST relies on standardized HTTP methods and status codes, GraphQL provides flexibility through query definitions and common patterns for data fetching.

API versioning, error handling, and pagination are crucial API design strategies. Implementing consistent versioning strategies, standardized error responses, and efficient pagination mechanisms ensures your RESTful and GraphQL APIs remain scalable and maintainable over time.

Yes, you can define API contracts for a new microservice before writing code. By designing resource naming, request/response formats, and error handling first, you establish a clear structure and specification that guides subsequent development and ensures consistency.
