SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill codifies API design best practices, including RESTfulness, GraphQL patterns, versioning, and developer-friendly interfaces.

Core Features & Use Cases

  • REST Maturity Guidance: From POX to HATEOAS.
  • Resource Naming Rules: Nouns, pluralization, and hierarchy.
  • Responses & Errors: Consistent payloads, status codes, and error formats.

Quick Start

Design a simple REST endpoint for /users and its 200 response with a standard error model.

FAQPage Schema
How do I design a REST API that follows best practices for versioning and consistency?

REST API design applies versioning strategies, resource naming conventions, and consistent response formats to ensure predictable interfaces. Use noun-based resource names, implement versioning through URLs or headers, and standardize status codes and error payloads across endpoints.

What's the difference between REST and GraphQL API design approaches?

REST uses fixed endpoints and HTTP verbs on resources; GraphQL uses a single endpoint with schema-driven queries. Both approaches require consistent naming, error handling, and documentation—GraphQL emphasizes schema definition while REST emphasizes resource hierarchy and status codes.

How do I handle pagination, errors, and status codes consistently across API endpoints?

Pagination, error handling, and status codes require standardized patterns across all endpoints. Define consistent request/response formats, use appropriate HTTP status codes, create a unified error model, and document pagination parameters to ensure developers understand expected behavior.

Can I apply API design patterns to both REST endpoints and GraphQL schemas?

Yes. API design principles like resource modeling, naming conventions, versioning, and self-describing interfaces apply to both REST and GraphQL. Each has different implementation mechanics—REST uses URL hierarchies and HTTP verbs; GraphQL uses schema definitions and resolver patterns.

What makes an API developer-friendly and predictable?

Developer-friendly APIs are predictable, consistent, and self-describing. Achieve this through clear resource naming, standardized request/response structures, explicit status codes, comprehensive error documentation, and consistent patterns across all endpoints.

Do I need to understand REST maturity levels to design modern APIs?

REST maturity levels guide API design evolution from simple POX (Plain Old XML) to advanced HATEOAS implementations. Understanding these levels helps you choose the right balance between simplicity and hypermedia-driven discoverability for your use case.
