AWS Step Functions API

description AWS Step Functions API Overview

For complex, multi-step business processes that involve multiple AWS services (e.g., process payment -> update inventory -> send email), Step Functions API is invaluable. It allows developers to define state machines that manage the state, retries, and error handling across disparate API calls, ensuring transactional integrity.

help AWS Step Functions API FAQ

What is the difference between Standard and Express AWS Step Functions workflows?

Standard Workflows are designed for durable, auditable executions and can run for as long as one year. Express Workflows target high-volume, short-duration workloads and have different execution guarantees, logging behavior, and pricing.

How does the Step Functions API define a workflow?

A workflow is described as a state machine using Amazon States Language, a JSON-based format. States can invoke AWS Lambda, wait, branch, run tasks in parallel, map over data, or call supported AWS services directly.

Can Step Functions retry a failed Lambda invocation automatically?

Yes. A Task state can define Retry rules with matching error names, delay intervals, backoff rates, and attempt limits, while Catch rules route failures to recovery states.

How is AWS Step Functions different from Amazon EventBridge?

Step Functions coordinates an explicit sequence and preserves workflow state, while EventBridge routes events between loosely coupled producers and targets. Many AWS systems use both: EventBridge starts a state machine, and Step Functions manages the multi-step process.
