OpenAPI 3.0: How to Design and Document APIs with the Latest OpenAPI Specification 3.0
The OpenAPI Specification (OAS), based on the original Swagger 2.0 specification, has emerged as the world’s standard for defining and describing RESTful APIs.
The next version of the OAS – 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.

Last month, the team released support for OAS 3.0 in the open source Swagger tooling, including the Swagger Editor and Swagger UI. This month, we are officially releasing support for designing and documenting APIs with OAS 3.0 in SwaggerHub!
In this free SwaggerHub training, we will look at what’s new in OAS 3.0, and show a live demo of defining APIs using OAS 3.0 in SwaggerHub.

We will cover:
• What’s new in OpenAPI 3.0?
• Transitioning from Swagger 2.0 to OAS 3.0
• Designing an API using OAS 3.0 on SwaggerHub
• Collaborative approach to API design and documentation with OAS 3.0 in SwaggerHub
