API Documentation Excellence
Design, write and maintain API documentation that developers actually use.
About this course
<p>Developers judge an API by its documentation. This course shows you how to <strong>design, write and maintain API documentation that developers actually use</strong> — from the reader’s journey and page structure, through endpoint reference, onboarding, errors, versioning and style, to docs-as-code pipelines and quality metrics.</p><p>It follows a half-day corporate workshop (about four hours of teaching and practice) made self-paced: the full 40-slide deck, six modules with quizzes, a hands-on lab where you document a real endpoint, a peer-review rubric and a final assessment.</p><p>Built for API developers, tech leads and technical writers.</p>

- Build quickstarts, authentication guides and code samples developers can trust
- Document errors, throttling, pagination, versioning and operational contracts
- Apply a clear, warm, direct and inclusive writing style
- Set up a docs-as-code pipeline and measure documentation quality
