Overview

This AWS Solutions Construct implements an Amazon API Gateway connected to an Amazon SQS queue pattern.

Here is a minimal deployable pattern definition:

const { ApiGatewayToSqs } = require('@aws-solutions-constructs/aws-apigateway-sqs');

new ApiGatewayToSqs(stack, 'ApiGatewayToSqsPattern', {
    apiGatewayProps: {},
    queueProps: {},
    deployDeadLetterQueue?: true,
    maxReceiveCount?: 3
});

Initializer

new ApiGatewayToSqs(scope: Construct, id: string, props: ApiGatewayToSqsProps);

Parameters

• scope Construct
• id string
• props ApiGatewayToSqsProps
