How To Get Started With OpenAPI 3.0

  May 23, 2018

The OpenAPI Specification (OAS) is the best open standard to drive and accelerate your API development. As the API economy grows larger and larger every year, it’s important that you are setting your APIs up for success by defining them in a format that humans and computers can easily comprehend.

The OAS specifies the rules and syntax required to describe the API’s interface. It has evolved to meet the needs of modern API teams and continues to introduce updates to make the specification simpler to use, and easier to understand.

The newest version of OpenAPI, OAS 3.0, was released last year and has seen wide adoption from developers and has been well received from the community. The OAS 3.0 structure is much simpler, relationships can be better expressed with links, multipart document handling is easier, content negation and many more features are now available for API aficionados to use in OAS 3.0.

While everyone wants to take advantage of the newest version, it can get tricky when you want to do so for an existing API.

Whether you have APIs defined in Swagger 2.0 that you want to migrate to OAS 3.0, or a lot of legacy APIs that don’t even have a definition in place, it’s not too late to make the switch to OpenAPI. There are a quite a few options out there to help you with this process, however, they are bulky and require a bit of a learning curve. Swagger provides a few tools to help you get on track quickly and easily so that you can focus on more important development tasks.

In our webinar “Migrating to OpenAPI 3.0: How to Convert Your Existing APIs with Swagger Tools” we’ll be covering what’s new to OAS 3.0, and how to easily create your OAS 3.0 definition when you already have existing API implementations or older Swagger definitions.

Here’s what you’ll be learning -

  1. What’s new in OAS 3.0
  2. How to generate OAS 3.0 definitions through code annotations using the SwaggerHub open source Maven plugin
  3. How to generate OAS 3.0 definitions from API end points using Swagger Inspector
  4. How to convert Swagger 2.0 definitions to OAS 3.0 definitions using SwaggerHub
  5. How to create consumer-friendly APIs using OAS 3.0 and SwaggerHub
