- 2. © 2019 IBM Corporation API the Docs | Case Study: Integration and automation create delightful API docs Agenda Today, we’ll show how we generate from OpenAPI 2 or 3, Markdown, and an SDK generator project. We'll show our authoring environment and fast, automated build. Finally, some bits about how we promote quality from up front guidance to post-build dashboards. 2
