You can now create Amazon API Gateway REST APIs to trigger a Synchronous Express Workflow from AWS Step Functions and respond with the output of that workflow.
AWS Step Functions Synchronous Express Workflows allows you to build business logic that involves orchestrating a workflow of different microservices. By integrating your REST API with Synchronous Express Workflows, customers can build APIs for interactive applications powered by a sequence of microservices. In addition, customers can use API Gateway to transform the workflow response before sending it back to the caller. For example, customers can build APIs that capture responses submitted through an online feedback form, process the data using a chain of microservices orchestrated by Synchronous Express Workflows, standardize the response using transformations in REST APIs, and return the reference number to the submitter.
