What is the OpenAPI Specification?

Why does it exist?

Structure of an OpenAPI document

How do we deal with Authentication and Authorization in OpenAPI Specification

Useful tools and libraries for working with the OpenAPI Specification

Best Practices for designing and documenting APIs using the OpenAPI Specification

The OpenAPI Specification, started in 2010, describes a standard and programming language-agnostic interface description for HTTP APIs, and includes support for REST APIs. In essence, it allows users to understand and interact with remote services with a minimal amount of implementation logic. 

This course will get not only into the ‘how’, but the ‘why’ of the OpenAPI specification. We’ll learn what the specification is, why it exists, and the structure of an OpenAPI document.

Next, in a series of video lessons and hands-on labs, we’ll systematically go through APIs that allow you to view users and retrieve records, as well as understand how to deal with Authentication and Authorization in the OpenAPI spec.

This course also looks at useful tools and libraries, and best practices for designing and documenting APIs using the OpenAPI specification. At the end of this course, you’ll have a comprehensive understanding of API security through the lens of OpenAPI.
