Properties
CacheKeyParameters
A list of request parameters whose values API Gateway caches.
virtual string[] CacheKeyParameters { get; }Property Value
System.String[]
Remarks
To be valid values for cacheKeyParameters , these parameters must also be specified for Method requestParameters .
CacheNamespace
Specifies a group of related cached parameters.
virtual string CacheNamespace { get; }Property Value
System.String
Remarks
By default, API Gateway uses the resource ID as the cacheNamespace . You can specify the same cacheNamespace across resources to return the same cached data for requests to different resources.
ConnectionId
The ID of the VpcLink used for the integration when connectionType=VPC_LINK and undefined, otherwise.
virtual string ConnectionId { get; }Property Value
System.String
Remarks
ConnectionType
The type of the network connection to the integration endpoint.
virtual string ConnectionType { get; }Property Value
System.String
Remarks
The valid value is INTERNET for connections through the public routable internet or VPC_LINK for private connections between API Gateway and a network load balancer in a VPC. The default value is INTERNET .
ContentHandling
Specifies how to handle request payload content type conversions.
virtual string ContentHandling { get; }Property Value
System.String
Remarks
Supported values are CONVERT_TO_BINARY and CONVERT_TO_TEXT , with the following behaviors:
If this property is not defined, the request payload will be passed through from the method request to integration request without modification, provided that the passthroughBehavior is configured to support payload pass-through.
Credentials
Specifies the credentials required for the integration, if any.
virtual string Credentials { get; }Property Value
System.String
Remarks
For AWS integrations, three options are available. To specify an IAM Role for API Gateway to assume, use the role's Amazon Resource Name (ARN). To require that the caller's identity be passed through from the request, specify the string arn:aws:iam::*:user/* . To use resource-based permissions on supported AWS services, specify null.
IntegrationHttpMethod
Specifies the integration's HTTP method type.
virtual string IntegrationHttpMethod { get; }Property Value
System.String
Remarks
For the Type property, if you specify MOCK , this property is optional. For Lambda integrations, you must set the integration method to POST . For all other types, you must specify this property.
IntegrationResponses
Specifies the integration's responses.
virtual object IntegrationResponses { get; }Property Value
System.Object
Remarks
PassthroughBehavior
Specifies how the method request body of an unmapped content type will be passed through the integration request to the back end without transformation.
virtual string PassthroughBehavior { get; }Property Value
System.String
Remarks
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.
RequestParameters
A key-value map specifying request parameters that are passed from the method request to the back end.
virtual object RequestParameters { get; }Property Value
System.Object
Remarks
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.
RequestTemplates
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.
virtual object RequestTemplates { get; }Property Value
System.Object
Remarks
The content type value is the key in this map, and the template (as a String) is the value.
TimeoutInMillis
Custom timeout between 50 and 29,000 milliseconds.
virtual Nullable<double> TimeoutInMillis { get; }Property Value
System.Nullable<System.Double>
Remarks
The default value is 29,000 milliseconds or 29 seconds.
Type
Specifies an API method integration type. The valid value is one of the following:.
string Type { get; }Property Value
System.String
Remarks
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.
Uri
Specifies Uniform Resource Identifier (URI) of the integration endpoint.
virtual string Uri { get; }Property Value
System.String
Remarks
For HTTP or HTTP_PROXY integrations, the URI must be a fully formed, encoded HTTP(S) URL according to the RFC-3986 specification for standard integrations. If connectionType is VPC_LINK specify the Network Load Balancer DNS name. 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, 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}
