	// AWS: for integrating the route or method request with an AWS service action,
	// including the Lambda function-invoking action. With the Lambda function-invoking
	// action, this is referred to as the Lambda custom integration. With any other AWS
	// service action, this is known as AWS integration. Supported only for WebSocket
	// APIs.
	//
	// AWS_PROXY: for integrating the route or method request with a Lambda function
	// or other AWS service action. This integration is also referred to as a Lambda
	// proxy integration.
	//
	// HTTP: for integrating the route or method request with an HTTP endpoint. This
	// integration is also referred to as the HTTP custom integration. Supported only
	// for WebSocket APIs.
	//
	// HTTP_PROXY: for integrating the route or method request with an HTTP endpoint,
	// with the client request passed through as-is. This is also referred to as HTTP
	// proxy integration. For HTTP API private integrations, use an HTTP_PROXY
	// integration.
	//

	// "loopback" endpoint without invoking any backend. Supported only for WebSocket
	// APIs.

	// you specify the ARN of an AWS Cloud Map service, API Gateway uses
	// DiscoverInstances to identify resources. You can use query parameters to target
	// specific resources. To learn more, see [DiscoverInstances]. For private integrations, all

	// only for WebSocket APIs.
	//
	// WHEN_NO_MATCH passes the request body for unmapped content types through to the
	// integration backend without transformation.
	//
	// NEVER rejects unmapped content types with an HTTP 415 Unsupported Media Type
	// response.
	//
	// WHEN_NO_TEMPLATES allows pass-through when the integration has no content types

	// unmapped content types will be rejected with the same HTTP 415 Unsupported Media
	// Type response.
