apiId

Type: string

The API identifier.


integrationType

Type: string

The integration type of an integration. One of the following:.

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.

MOCK : for integrating the route or method request with API Gateway as a "loopback" endpoint without invoking any backend. Supported only for WebSocket APIs.


connectionId?

Type: string (optional)

The ID of the VPC link for a private integration.

Supported only for HTTP APIs.


connectionType?

Type: string (optional)

The type of the network connection to the integration endpoint.

Specify INTERNET for connections through the public routable internet or VPC_LINK for private connections between API Gateway and resources in a VPC. The default value is INTERNET .


contentHandlingStrategy?

Type: string (optional)

Supported only for WebSocket APIs.

Specifies how to handle response payload content type conversions. Supported values are CONVERT_TO_BINARY and CONVERT_TO_TEXT , with the following behaviors:

CONVERT_TO_BINARY : Converts a response payload from a Base64-encoded string to the corresponding binary blob.

CONVERT_TO_TEXT : Converts a response payload from a binary blob to a Base64-encoded string.

If this property is not defined, the response payload will be passed through from the integration response to the route response or method response without modification.


credentialsArn?

Type: string (optional)

Specifies the credentials required for the integration, if any.

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, don't specify this parameter.


description?

Type: string (optional)

The description of the integration.


integrationMethod?

Type: string (optional)

Specifies the integration's HTTP method type.


integrationSubtype?

Type: string (optional)

Supported only for HTTP API AWS_PROXY integrations.

Specifies the AWS service action to invoke. To learn more, see Integration subtype reference .


integrationUri?

Type: string (optional)

For a Lambda integration, specify the URI of a Lambda function.

For an HTTP integration, specify a fully-qualified URL.

For an HTTP API private integration, specify the ARN of an Application Load Balancer listener, Network Load Balancer listener, or AWS Cloud Map service. If 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 resources must be owned by the same AWS account .


passthroughBehavior?

Type: string (optional)

Specifies the pass-through behavior for incoming requests based on the Content-Type header in the request, and the available mapping templates specified as the requestTemplates property on the Integration resource.

There are three valid values: WHEN_NO_MATCH , WHEN_NO_TEMPLATES , and NEVER . Supported 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 mapped to templates. However, if there is at least one content type defined, unmapped content types will be rejected with the same HTTP 415 Unsupported Media Type response.


payloadFormatVersion?

Type: string (optional)

Specifies the format of the payload sent to an integration.

Required for HTTP APIs. For HTTP APIs, supported values for Lambda proxy integrations are 1.0 and 2.0 . For all other integrations, 1.0 is the only supported value. To learn more, see Working with AWS Lambda proxy integrations for HTTP APIs .


requestParameters?

Type: any (optional)

For WebSocket APIs, a key-value map specifying request parameters that are passed from the method request to the backend.

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 backend. 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.

For HTTP API integrations with a specified integrationSubtype , request parameters are a key-value map specifying parameters that are passed to AWS_PROXY integrations. You can provide static values, or map request data, stage variables, or context variables that are evaluated at runtime. To learn more, see Working with AWS service integrations for HTTP APIs .

For HTTP API integrations without a specified integrationSubtype request parameters are a key-value map specifying how to transform HTTP requests before sending them to the backend. The key should follow the pattern :<header|querystring|path>. where action can be append , overwrite or remove . For values, you can provide static values, or map request data, stage variables, or context variables that are evaluated at runtime. To learn more, see Transforming API requests and responses .


requestTemplates?

Type: any (optional)

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. Supported only for WebSocket APIs.


responseParameters?

Type: any (optional)

Supported only for HTTP APIs.

You use response parameters to transform the HTTP response from a backend integration before returning the response to clients. Specify a key-value map from a selection key to response parameters.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).


addDependency(target)

public addDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.


addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.


addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.


addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.


addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).


applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

  • policy RemovalPolicy
  • options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

See also: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options


getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

  • attributeName string — The name of the attribute.
  • typeHint ResolutionTypeHint

Returns

  • Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.


getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
