# Create an AWS Step Functions workflow to integrate with Amazon SQS using CDK.



This CDK application deploys a Step Functions workflow, that takes in a payload and sends part of it to an Amazon SQS. In this pattern, the state machine does not wait for a callback from the queue. The application contains the minimum IAM resources required to run the workflow.
