Overview What You Will Learn Curriculum Instructor

Course Overview

Designing APIs efficiently and clearly is essential for modern software development, and OpenAPI 3.1 is a leading standard for achieving this. OpenAPI enables teams to create robust, standardized, and well-documented APIs that are easy to maintain and consume. Learning OpenAPI 3.1 equips developers, architects, and technical writers with critical skills to design, describe, and maintain APIs that meet industry best practices and accelerate application development.

This course begins with an introduction to APIs and highlights the importance of detailed API descriptions. It then traces the evolution of OpenAPI from Swagger to its current significance. Learners dive into OpenAPI reference documentation, covering definitions, formats, versioning, and JSON schema standards. Next, the course guides the creation of a first OpenAPI document, setting up API metadata, defining paths, managing operations, and using reusable components. Further sections explore describing security schemes like OAuth 2.0, OpenID Connect, and Mutual TLS, followed by advanced features such as links, callbacks, webhooks, schema inheritance, and document splitting. The course concludes with a look at OpenAPI tooling to resolve references, mock APIs, and interact with endpoints.

By the end of this course, you will confidently design, document, secure, and interact with APIs using OpenAPI 3.1.
