- 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

About this course
Developers judge an API by its documentation. This course shows you how to design, write and maintain API documentation that developers actually use — from the reader’s journey and page structure, through endpoint reference, onboarding, errors, versioning and style, to docs-as-code pipelines and quality metrics.
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.
Built for API developers, tech leads and technical writers.
