AWS::ApiGateway::Method Integration

Integration is a property of the AWS::ApiGateway::Method resource that specifies information about the target backend that a method calls.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON


{
  "CacheKeyParameters" : [ String, ... ],
  "CacheNamespace" : String,
  "ConnectionId" : String,
  "ConnectionType" : String,
  "ContentHandling" : String,
  "Credentials" : String,
  "IntegrationHttpMethod" : String,
  "IntegrationResponses" : [ IntegrationResponse, ... ],
  "PassthroughBehavior" : String,
  "RequestParameters" : {Key : Value, ...},
  "RequestTemplates" : {Key : Value, ...},
  "TimeoutInMillis" : Integer,
  "Type" : String,
  "Uri" : String
}

Properties

CacheKeyParameters

A list of request parameters whose values API Gateway caches. For cases where the integration type allows for RequestParameters to be set, these parameters must also be specified in RequestParameters to be supported in CacheKeyParameters.

Required: No

Type: List of String

Update requires: No interruption

CacheNamespace

An API-specific tag group of related cached parameters.

Required: No

Type: String

Update requires: No interruption

ConnectionId

The ID of the VpcLink used for the integration when connectionType=VPC_LINK, otherwise undefined.

Required: No

Type: String

Update requires: No interruption

ConnectionType

The type of the network connection to the integration endpoint. 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.

Required: No

Type: String

Update requires: No interruption

ContentHandling

Specifies how to handle request payload content type conversions. Valid values are:

CONVERT_TO_BINARY: Converts a request payload from a base64-encoded string to a binary blob.
CONVERT_TO_TEXT: Converts a request payload from a binary blob to a base64-encoded string.

If this property isn't defined, the request payload is passed through from the method request to the integration request without modification, provided that the PassthroughBehaviors property is configured to support payload pass-through.

Required: No

Type: String

Update requires: No interruption

Credentials

The credentials that are required for the integration. To specify an AWS Identity and Access Management (IAM) role that API Gateway assumes, specify the role's Amazon Resource Name (ARN). To require that the caller's identity be passed through from the request, specify arn:aws:iam::*:user/*.

To use resource-based permissions on the AWS Lambda (Lambda) function, don't specify this property. Use the AWS::Lambda::Permission resource to permit API Gateway to call the function. For more information, see Allow Amazon API Gateway to Invoke a Lambda Function in the AWS Lambda Developer Guide.

Required: No

Type: String

Update requires: No interruption

IntegrationHttpMethod

The integration's HTTP method type.

For the Type property, if you specify MOCK, this property is optional. For all other types, you must specify this property.

Required: Conditional

Type: String

Update requires: No interruption

IntegrationResponses

The response that API Gateway provides after a method's backend completes processing a request. API Gateway intercepts the response from the backend so that you can control how API Gateway surfaces backend responses. For example, you can map the backend status codes to codes that you define.

Required: No

Type: List of IntegrationResponse

Update requires: No interruption

PassthroughBehavior

Indicates when API Gateway passes requests to the targeted backend. This behavior depends on the request's Content-Type header and whether you defined a mapping template for it.

For more information and valid values, see the passthroughBehavior field in the API Gateway API Reference.

Required: No

Type: String

Update requires: No interruption

RequestParameters

The request parameters that API Gateway sends with the backend request. Specify request parameters as key-value pairs (string-to-string mappings), with a destination as the key and a source as the value.

Specify the destination by using the following pattern integration.request.location.name, where location is query string, path, or header, and name is a valid, unique parameter name.

The source must be an existing method request parameter or a static value. You must enclose static values in single quotation marks and pre-encode these values based on their destination in the request.

Required: No

Type: Map of String

Update requires: No interruption

RequestTemplates

A map of Apache Velocity templates that are applied on the request payload. The template that API Gateway uses is based on the value of the Content-Type header that's sent by the client. The content type value is the key, and the template is the value (specified as a string), such as the following snippet:

"application/json": "{\n \"statusCode\": 200\n}"

For more information about templates, see API Gateway Mapping Template and Access Logging Variable Reference in the API Gateway Developer Guide.

Required: No

Type: Map of String

Update requires: No interruption

TimeoutInMillis

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

Required: No

Type: Integer

Update requires: No interruption

Type

The type of backend that your method is running, such as HTTP or MOCK. For all of the valid values, see the type property for the Integration resource in the Amazon API Gateway REST API Reference.

Required: No

Type: String

Update requires: No interruption

Uri

The Uniform Resource Identifier (URI) for the integration.

If you specify HTTP for the Type property, specify the API endpoint URL.

If you specify MOCK for the Type property, don't specify this property.

If you specify AWS for the Type property, specify an AWS service that follows this form: arn:aws:apigateway:region:subdomain.service|service:path|action/service_api. For example, a Lambda function URI follows this form: arn:aws:apigateway:region:lambda:path/path. The path is usually in the form /2015-03-31/functions/LambdaFunctionARN/invocations. For more information, see the uri property of the Integration resource in the Amazon API Gateway REST API Reference.

If you specified HTTP or AWS for the Type property, you must specify this property.

Required: Conditional

Type: String
