	//    content type does not match any content type associated with the mapping
	//    templates defined in the integration request.
	//
	//    * WHEN_NO_TEMPLATES: passes the method request body through the integration
	//    request to the back end without transformation when no mapping template
	//    is defined in the integration request. If a template is defined when this
	//    option is selected, the method request of an unmapped content-type will

	//

	TimeoutInMillis *int64 `locationName:"timeoutInMillis" type:"integer"`

	// Specifies the TLS configuration for an integration.
	TlsConfig *TlsConfig `locationName:"tlsConfig" type:"structure"`

	// Specifies an API method integration type. The valid value is one of the following:
	//
	//    * AWS: for integrating the API 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.
	//
	//    * AWS_PROXY: for integrating the API method request with the Lambda function-invoking
	//    action with the client request passed through as-is. This integration
	//    is also referred to as the Lambda proxy integration.
	//
	//    * HTTP: for integrating the API method request with an HTTP endpoint,
	//    including a private HTTP endpoint within a VPC. This integration is also
	//    referred to as the HTTP custom integration.
	//
	//    * HTTP_PROXY: for integrating the API method request with an HTTP endpoint,
	//    including a private HTTP endpoint within a VPC, with the client request
	//    passed through as-is. This is also referred to as the HTTP proxy integration.
	//
	//    * MOCK: for integrating the API method request with API Gateway as a "loop-back"
	//    endpoint without invoking any backend.
	//
	// For the HTTP and HTTP proxy integrations, each integration can specify a
	// protocol (http/https), port and path. Standard 80 and 443 ports are supported
	// as well as custom ports above 1024. An HTTP or HTTP proxy integration with
	// a connectionType of VPC_LINK is referred to as a private integration and
	// uses a VpcLink to connect API Gateway to a network load balancer of a VPC.
	Type IntegrationType `locationName:"type" type:"string" enum:"true"`

	// Specifies Uniform Resource Identifier (URI) of the integration endpoint.
	//
	//    * For HTTP or HTTP_PROXY integrations, the URI must be a fully formed,
	//    encoded HTTP(S) URL according to the RFC-3986 specification (https://en.wikipedia.org/wiki/Uniform_Resource_Identifier),
	//    for either standard integration, where connectionType is not VPC_LINK,
	//    or private integration, where connectionType is VPC_LINK. For a private
	//    HTTP integration, the URI is not used for routing.
	//
	//    * For AWS or AWS_PROXY integrations, the URI is of the form arn:aws:apigateway:{region}:{subdomain.service|service}:path|action/{service_api}.
	//    Here, {Region} is the API Gateway region (e.g., us-east-1); {service}
	//    is the name of the integrated AWS service (e.g., s3); and {subdomain}
	//    is a designated subdomain supported by certain AWS service for fast host-name
	//    lookup. action can be used for an AWS service action-based API, using
	//    an Action={name}&{p1}={v1}&p2={v2}... query string. The ensuing {service_api}
	//    refers to a supported action {name} plus any required input parameters.
	//    Alternatively, path can be used for an AWS service path-based API. The
	//    ensuing service_api refers to the path to an AWS service resource, including
	//    the region of the integrated AWS service, if applicable. For example,
	//    for integration with the S3 API of GetObject (https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGET.html),
	//    the uri can be either arn:aws:apigateway:us-west-2:s3:action/GetObject&Bucket={bucket}&Key={key}
	//    or arn:aws:apigateway:us-west-2:s3:path/{bucket}/{key}
