RESTful API design best practices involve structuring URLs logically around resources and using standard HTTP methods like GET, POST, PUT, and DELETE. This ensures consistent, scalable web service architecture and clear communication.

Designing a GraphQL schema requires defining type definitions, queries, and mutations effectively. Implementing pagination within these schemas ensures efficient data retrieval for GraphQL APIs.

API authentication can be implemented using JWT for stateless token verification and OAuth 2.0 flows for secure delegated access. Implementing rate limiting alongside these measures protects APIs from abuse.

Documenting APIs using OpenAPI specifications involves detailing endpoints, request parameters, and response schemas. Effective API documentation ensures developers understand integration requirements and expected behaviors.

API error handling requires returning appropriate HTTP status codes, such as 400 for bad requests or 404 for not found. Consistent error handling and input validation improve API reliability.

Choosing GraphQL over RESTful APIs depends on whether clients need flexible data fetching to avoid over-fetching. RESTful APIs are often preferred for standardized caching and simpler endpoint structures.
