	IntegrationResponses map[string]types.IntegrationResponse

	// Specifies how the method request body of an unmapped content type will be passed
	// through the integration request to the back end without transformation. A
	// content type is unmapped if no mapping template is defined in the integration or
	// the content type does not match any of the mapped content types, as specified in
	// requestTemplates. The valid value is one of the following:
	//
	// * WHEN_NO_MATCH:
	// passes the method request body through the integration request to the back end
	// without transformation when the method request 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 be
	// rejected with an HTTP 415 Unsupported Media Type response.
	//
	// * NEVER: rejects the
	// method request with an HTTP 415 Unsupported Media Type response when either the
	// method request content type does not match any content type associated with the
	// mapping templates defined in the integration request or no mapping template is
	// defined in the integration request.
	PassthroughBehavior *string

	// A key-value map specifying request parameters that are passed from the method
	// request to the back end. The key is an integration request parameter name and
	// the associated value is a method request parameter value or static value that
	// must be enclosed within single quotes and pre-encoded as required by the back
	// end. The method request parameter value must match the pattern of
	// method.request.{location}.{name}, where location is querystring, path, or header
	// and name must be a valid and unique method request parameter name.
	RequestParameters map[string]string

	// Represents a map of Velocity templates that are applied on the request payload
	// based on the value of the Content-Type header sent by the client. The content
	// type value is the key in this map, and the template (as a String) is the value.
	RequestTemplates map[string]string

	// Custom timeout between 50 and 29,000 milliseconds. The default value is 29,000
	// milliseconds or 29 seconds.
	TimeoutInMillis int32

	// Specifies the TLS configuration for an integration.
	TlsConfig *types.TlsConfig

	// 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 types.IntegrationType

	// 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}
