This demonstrates how to use AWS Step Functions to make a call to Amazon API Gateway to interact with a service on AWS Fargate and to check whether the call succeeded.
In this project, Step Functions calls an API Gateway endpoint, checking the response status code, and notifying a specified SNS topic of the success or failure of the API call.
The project involves the following steps:
Calls an API Gateway HTTP endpoint using an IAM role for authentication.
Checks if the response status code is 200 using a Choice state.
If the response status code is 200, publishes a success message to an SNS topic using a Task state.
If the response status code is not 200, publishes a failure message to the same SNS topic using a Task state.
