Create an API Gateway HTTP APIs endpoint that starts a Step Functions syncronous Express Workflow
The SAM template deploys a HTTP APIs endpoint with an integration that syncronsouly invokes a Step Functions Express workflow and returns the response. The SAM template contains the minimum IAM resources required to run the application with logging enabled.
The HTTP's API endpoint can be called from an application (e.g. a web front end) to run an express workflow and return the result.

sam deploy --guidedTesting
Run the following command to send an HTTP `POST` request to the HTTP APIs endpoint. Note, you must edit the {HelloWorldApi} placeholder with the URL of the deployed HTTP APIs endpoint. This is provided in the stack outputs:
curl --location --request POST '{HelloWorldApi}' --header 'Content-Type: application/json' --data-raw '{ "IsHelloWorldExample": "Yes" }'Cleanup
1. Delete the stack:
sam delete --stack-name STACK_NAME.2. Confirm the stack has been deleted:
aws cloudformation list-stacks --query "StackSummaries[?contains(StackName,'STACK_NAME')].StackStatus"Created by:
