# API Gateway extensions for AWS SAM
<a name="sam-specification-api-gateway-extensions"></a>

API Gateway extensions, specifically designed for AWS, provide additional customizations and functionality for designing and managing APIs. API Gateway extensions are extensions to the OpenAPI specification that support the AWS-specific authorization and API Gateway-specific API integrations. For more information about API Gateway extensions, refer to [API Gateway Extensions to OpenAPI](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-swagger-extensions.html).

AWS SAM supports a subset of API Gateway extensions. To see which API Gateway extensions are supported by AWS SAM, refer to the following table.
