API Platform & Lifecycle · Developer Experience
Documentation That Developers Actually Use
Reference docs, guides, quickstarts and interactive consoles.
Great API docs combine reference (generated from the spec: every endpoint, field, error), guides (concepts like authentication, pagination, webhooks, idempotency), quickstarts (first successful call in under 5 minutes), recipes for common tasks, and a changelog. Use modern renderers (Redocly, Scalar, Stoplight Elements), include copy-paste examples in several languages, and keep docs in the same repo/PR as the API change.
The documentation set
| Doc type | Answers | Source |
|---|---|---|
| Quickstart | How do I make my first call? | Handwritten, tested |
| Guides | How does auth/pagination/webhooks work? | Handwritten |
| API reference | What does this endpoint accept/return? | Generated from spec |
| Recipes | How do I accomplish X? | Handwritten, tested code |
| Changelog | What changed and do I need to act? | Generated + curated |

Common pitfalls
- Reference-only docs with no conceptual guides.
- Examples that don't run (test them in CI).
- Docs updated after releases instead of in the same PR.
Key points
- Quickstart, guides, reference, recipes, changelog
- Generated reference from the spec
- Tested examples

Practice questions
What is 'time to first call' and why does it matter?
Answer
How long a new developer takes to make a successful API request; it's a key DX metric because friction there loses adopters.
How do you keep code examples in docs from breaking?
Answer
Store them as runnable snippets tested in CI against a sandbox, or generate them from SDKs.
