Overview

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

Here is a minimal deployable pattern definition in Typescript:

import { ApiGatewayToSqs, ApiGatewayToSqsProps } from "@aws-solutions-constructs/aws-apigateway-sqs";

new ApiGatewayToSqs(this, 'ApiGatewayToSqsPattern', {});

Initializer

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

Parameters

• scope Construct
• id string
• props ApiGatewayToSqsProps

apiGatewayProps?	api.RestApiProps	Optional user-provided props to override the default props for the API Gateway.
queueProps?	sqs.QueueProps	Optional user-provided props to override the default props for the queue.
deployDeadLetterQueue?	boolean	Whether to deploy a secondary queue to be used as a dead letter queue. Defaults to true.
maxReceiveCount	number	The number of times a message can be unsuccessfully dequeued before being moved to the dead-letter queue.
allowCreateOperation?	boolean	Whether to deploy an API Gateway Method for Create operations on the queue (i.e. sqs:SendMessage).
createRequestTemplate?	string	Override the default API Gateway Request template for Create method, if allowCreateOperation set to true.
allowReadOperation?	boolean	Whether to deploy an API Gateway Method for Read operations on the queue (i.e. sqs:ReceiveMessage).
