# OpenAPI extensions for API Gateway
<a name="api-gateway-swagger-extensions"></a>

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

**Tip**  
To understand how the API Gateway extensions are used in an application, you can use the API Gateway console to create a REST API or HTTP API and export it to an OpenAPI definition file. For more information on how to export an API, see [Export a REST API from API Gateway](api-gateway-export-api.md) and [Export HTTP APIs from API Gateway](http-api-export.md).
