API Gateway Extensions to OpenAPI

The API Gateway extensions support the AWS-specific authorization and API Gateway-specific API integrations. In this section, we will describe the API Gateway extensions to the OpenAPI specification for REST APIs.


To understand how the API Gateway extensions are used in an app, you can use the API Gateway console to create an API and export it to a OpenAPI definition file. For more information on how to export an API, see Export a REST API.
