Core principles for designing RESTful APIs involve adopting resource-oriented architecture, using correct HTTP method semantics, and implementing standard patterns for pagination, filtering, and error handling to ensure scalability and usability.

Designing a GraphQL schema for efficient data fetching requires a schema-first development approach, defining clear query structures, and applying patterns that minimize over-fetching and optimize data retrieval operations.

The best way to handle API versioning for maintainability involves adopting structured versioning strategies that prevent breaking changes, ensuring consistent developer experience and long-term scalability for your software architecture.

Implementing pagination and filtering in HTTP semantics requires applying standard API patterns to resource endpoints, allowing clients to request specific data subsets efficiently while maintaining RESTful design constraints.

Choose GraphQL over REST when your API architecture demands highly flexible, client-driven data fetching, whereas REST suits resource-oriented architectures requiring standard HTTP semantics and predictable caching behaviors.

Structuring error handling in an API for better developer experience requires implementing consistent error response patterns, utilizing proper HTTP status codes, and providing clear, actionable error messages to API consumers.
