Exporting HTTP APIs as OpenAPI 3.0 Now Supported by Amazon API Gateway
You can now export an OpenAPI 3.0 compliant API definition file from HTTP APIs in Amazon API Gateway. API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. Previously, you had to import OpenAPI 3.0 API definitions to create HTTP APIs in API Gateway.
The OpenAPI specification is standard for documenting APIs, and OpenAPI 3.0 is the latest version of the OpenAPI specification. OpenAPI 3.0 offers a number of improvements, such as a simpler structure for defining APIs and more reusable components to minimize duplication, compared to OpenAPI 2.0. With support for OpenAPI 3.0, you can improve your API development workflows by easily integrating with other tools and API solutions in the market.
