Frequently Asked Questions
Short answer: start small, be hands-on, and build repeatable habits.
Here’s a practical path that works:
-
Learn the essentials
- HTTP methods (GET, POST, PUT, PATCH, DELETE)
- URLs, headers, auth (API keys, OAuth 2.0), rate limits
- Request/response bodies (usually JSON) and status codes
- Common patterns: pagination, filtering, error formats
-
Ship one end-to-end endpoint doc
- Overview: what the endpoint does and the base URL
- Auth: how to get credentials and send them
- Parameters: path/query params with types and examples
- Examples: a
curlrequest and a realistic JSON response - Errors: status codes, messages, and how to fix them
- Quickstart: a tiny “hello world” that makes a successful call
- Tip: pick a simple public API from a directory like public-apis.io and focus on one endpoint.
-
Use the right starter books
- Docs for Developers — approachable, hands-on guidance for engineers
- Designing Web APIs — the bigger picture across the API lifecycle
- The API University Series — targeted deep dives as you need them
- When you’re ready to level up process and automation, add Docs Like Code
-
Adopt a minimal toolchain from day one
- OpenAPI 3.1 as your single source of truth
- Git + Markdown for versioned writing and lightweight reviews
- Preview your spec with Swagger UI or Redocly; publish with MkDocs or Docusaurus
-
Practice in short feedback loops
- Write → test the examples yourself → have a developer try them → iterate
-
Avoid common pitfalls
- Out-of-date examples, missing auth steps, and inconsistent naming
If you do nothing else: document one great endpoint, keep it in Git, and describe it with OpenAPI. You’ll learn 80% of what you need by doing that well.
-
Docs as Code means you treat documentation like software:
- Write in plain text (often Markdown)
- Store everything in Git
- Review changes via pull requests
- Automate previews, checks, and publishing with CI/CD
- Keep your API spec (OpenAPI) as the source of truth
It’s a strong fit if you:
- Work in a DevOps or engineering-heavy environment
- Need docs and code to stay tightly in sync
- Want clear review workflows, history, and rollbacks
- Maintain multiple API versions or ship frequently
It may be overkill if you:
- Have a very small team and rarely update docs
- Prefer a simple WYSIWYG editor and minimal process
- Don’t need versioning, automation, or code reviews
How to pilot it (in a week):
- Move your docs to a Git repo (GitHub/GitLab/Bitbucket)
- Add your OpenAPI 3.1 spec to the repo
- Generate and preview docs with Swagger UI or Redocly
- Publish a site with MkDocs or Docusaurus
- Add CI to build a preview on every pull request
- Set up basic quality checks (Spectral for OpenAPI, Vale for prose)
For a step-by-step playbook, read Docs Like Code by Anne Gentle. It covers workflows, collaboration models, and automation patterns you can adopt incrementally.
If your goal is tooling fluency, follow this path:
- Get hands-on with OpenAPI
- Read: Designing APIs with Swagger and OpenAPI (Josh Ponelat & Lukas Rosenstock)
- Why: Practical, step-by-step workflows for writing specs, organizing endpoints, and crafting clear descriptions
- Practice: Author an OpenAPI 3.1 spec, then render it with Swagger UI or Redocly to see how structure turns into developer-friendly docs
- Ground your work in solid REST conventions
- Read: REST API Design Rulebook (Mark Masse)
- Why: Naming, resources, and status-code discipline that make your spec—and docs—consistent and predictable
- Level up consistency and patterns
- Read: API Design Patterns (JJ Geewax)
- Why: Patterns and anti-patterns that improve API design clarity and the documentation that explains those designs
- Deep-dive by topic as needed
- Read: The API University Series (Matthias Biehl)
- Why: Accessible guides across design, documentation, and security for targeted skills
Pro tip: Learn OpenAPI first, then iterate in a tight loop—edit the spec, render it, and test the examples until the output feels effortless for developers.
Pick tools that fit your workflow, but keep OpenAPI as your source of truth.
Core stack
- Spec and design: OpenAPI 3.1, Swagger Editor, Stoplight Studio (great for visual design-first)
- Rendering/portals: Redocly (polished portals), ReadMe (hosted, interactive, excellent DX), Stoplight (design-to-portal)
- Authoring platforms: Docusaurus or MkDocs (Git-based, customizable), GitBook (hosted, friendly), Archbee (fast to ship, collaborative)
- Testing and examples: Postman (collections, mock servers), Prism (mocking), Insomnia (testing)
- Generation: OpenAPI Generator or Swagger Codegen (SDKs and snippets)
- Quality and workflows: Spectral (OpenAPI linting), Vale (prose/style), CI/CD via GitHub Actions/GitLab CI
Quick picks
- Need a hosted, low-friction portal with “try it” built in? → ReadMe or Archbee
- Want a code-first, Git workflow with deep customization? → MkDocs or Docusaurus + Redocly
- Prefer design-first with visual modeling? → Stoplight Studio
Best practices
- Keep one OpenAPI spec as the canonical source of truth
- Automate previews on every pull request so reviewers see the real site
- Lint your spec and prose to prevent quality regressions
- Generate examples, snippets, and SDKs from the spec to stay consistent
