    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.
