OpenAPI 3.0: How to Design and Document APIs with the Latest OpenAPI Specification

The next version of the OpenAPI Specification – version 3.0 – is officially released, and comes with a host of rich, expressive capabilities for your API design and documentation. Some of these capabilities include support for describing callbacks, links to express relationships between operations, enhanced examples, and a simplified structure for better reusability. SwaggerHub now offers support for designing and documenting APIs with OpenAPI 3.0, as well as the ability to convert APIs defined with Swagger 2.0 to the latest version of the specification.

In this free SwaggerHub training, we look at what’s new in OAS 3.0, and show a live demo of defining APIs using OAS 3.0 in SwaggerHub. We also cover transitioning from Swagger 2.0 to OpenAPI 3.0, and how to start using OAS 3.0 for API design and documentation.

Get started with OpenAPI 3.0 today

If you have existing APIs defined with Swagger 2.0, you can easily import them into SwaggerHub and get started with OAS 3.0 today. APIs can quickly get converted to the new format, making it easy to start designing and documenting your APIs with the latest version of the specification. If you’re not ready to transition your existing APIs, you can also try out any of our template APIs and experiment with OAS 3.0.
