Implements IInterceptor

A Lambda-based interceptor for Gateway.

Interceptors allow you to run custom code during each invocation of your gateway:

• REQUEST interceptors execute before calling the target
• RESPONSE interceptors execute after the target responds

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as bedrock_agentcore_alpha from '@aws-cdk/aws-bedrock-agentcore-alpha';
import { aws_lambda as lambda } from 'aws-cdk-lib';

declare const function_: lambda.Function;
const lambdaInterceptor = bedrock_agentcore_alpha.LambdaInterceptor.forRequest(function_, /* all optional props */ {
  passRequestHeaders: false,
});

interceptionPoint🔹

Type: InterceptionPoint

The interception point (REQUEST or RESPONSE).

Methods

Name	Description
bind(_scope, gateway)🔹	Binds this Lambda interceptor to a Gateway.
static forRequest(lambdaFunction, options?)🔹	Create a REQUEST interceptor that executes before the gateway calls the target.
static forResponse(lambdaFunction, options?)🔹	Create a RESPONSE interceptor that executes after the target responds.

---

bind(_scope, gateway)🔹

public bind(_scope: Construct, gateway: IGateway): InterceptorBindConfig

Parameters

• _scope Construct — The construct scope (currently unused, reserved for future extensions).
• gateway IGateway — The gateway this interceptor is being bound to.

Returns

• InterceptorBindConfig

Binds this Lambda interceptor to a Gateway.

This method:

1. Grants the Gateway's IAM role permission to invoke the Lambda function
2. Returns the CloudFormation configuration for this interceptor

---

static forRequest(lambdaFunction, options?)🔹

public static forRequest(lambdaFunction: IFunction, options?: InterceptorOptions): LambdaInterceptor

Parameters

• lambdaFunction IFunction — The Lambda function to invoke.
• options InterceptorOptions — Optional configuration for the interceptor.

Returns

• LambdaInterceptor

Create a REQUEST interceptor that executes before the gateway calls the target.

Important: When this interceptor is added to a gateway, the gateway's IAM role will automatically be granted lambda:InvokeFunction permission on the specified Lambda function.

---

static forResponse(lambdaFunction, options?)🔹

public static forResponse(lambdaFunction: IFunction, options?: InterceptorOptions): LambdaInterceptor

Parameters

• lambdaFunction IFunction — The Lambda function to invoke.
• options InterceptorOptions — Optional configuration for the interceptor.

Returns

• LambdaInterceptor

Create a RESPONSE interceptor that executes after the target responds.

Important: When this interceptor is added to a gateway, the gateway's IAM role will automatically be granted lambda:InvokeFunction permission on the specified Lambda function.
