Designing RESTful APIs requires defining clear URL structures, naming conventions, and HTTP method usage for proper routing. You establish consistent request and response patterns with correct HTTP status codes to communicate outcomes effectively across new or existing endpoints.

API request validation using Zod schemas ensures input integrity by defining structured data constraints for incoming HTTP requests. This process validates request payloads against expected types and formats before processing, preventing invalid data from reaching your endpoint logic.

HTTP status codes and API error handling patterns require consistent response structures for successful and failed requests. You implement standardized error responses with appropriate HTTP status codes, ensuring clients receive predictable feedback for validation failures, authentication issues, or routing errors.

Documenting REST API endpoints for OpenAPI or Swagger involves generating standard specifications that describe URL structures, HTTP methods, and request response patterns. This provides interactive documentation for consumers, detailing authentication requirements, input validation rules, and rate limiting headers.

Implementing API authentication and versioning strategies involves defining secure access patterns and managing endpoint revisions. You establish authentication protocols to protect routes and apply versioning strategies to maintain backward compatibility while evolving your RESTful API architecture.

Structuring a microservice API architecture requires defining independent endpoint boundaries, consistent error responses, and secure authentication patterns. This approach ensures each service maintains standardized routing, input validation, and documentation, allowing scalable and maintainable RESTful API implementations.
