No matter how big or small your API, no matter the audience, internal or external, you need to provide clear and precise documentation so that others know how to use it. Since its inception as Swagger almost ten years ago, OpenAPI has been steadily gaining ground as the de facto specification for describing REST APIs. Whether your API is yet to be built or has been around for a decade, OpenAPI is a tool you can use to document all the parts of your APIs.
In this May 2nd, 2019 presentation, Ben Ramsey introduces you to the basic concepts of OpenAPI. He’ll use it to create documentation for a simple API and leave you with a few tips, tricks, and gotchas that he has learned along the way. You should be able to take what you’ve learned and immediately begin describing your APIs with OpenAPI.
