Back to [Step Functions](/docs/services/stepfunctions/index.md). ## Summary | Category | ✅ Supported | | --- | --- | | State machines | 6 | | Executions | 6 | | Tags | 3 | --- ## Endpoints ### State machines | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `CreateStateMachine` | ✅ Supported | Validates the ASL; idempotent — returns existing if name+def match | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_CreateStateMachine.html) | | `DescribeStateMachine` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_DescribeStateMachine.html) | | `ListStateMachines` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_ListStateMachines.html) | | `DeleteStateMachine` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_DeleteStateMachine.html) | | `UpdateStateMachine` | ✅ Supported | Definition/roleArn/loggingConfiguration/tracingConfiguration; no versioning (publish) | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_UpdateStateMachine.html) | | `DescribeStateMachineForExecution` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_DescribeStateMachineForExecution.html) | ### Executions | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `StartExecution` | ✅ Supported | Interprets the ASL; returns while the execution is RUNNING, as AWS does; a standard workflow's RUNNING and terminal status transitions each emit a Step Functions Execution Status Change event to the default EventBridge bus | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_StartExecution.html) | | `StartSyncExecution` | ✅ Supported | EXPRESS only — same interpreter, run to completion before returning; EXPRESS executions do not emit EventBridge events, matching AWS | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_StartSyncExecution.html) | | `DescribeExecution` | ✅ Supported | Real status, output, error and cause | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_DescribeExecution.html) | | `ListExecutions` | ✅ Supported | statusFilter (validated against the ExecutionStatus enum) and maxResults honoured; no pagination token | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_ListExecutions.html) | | `GetExecutionHistory` | ✅ Supported | Real state-transition events in AWS's vocabulary; readable while RUNNING | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_GetExecutionHistory.html) | | `StopExecution` | ✅ Supported | Interrupts a running execution; it reaches ABORTED asynchronously; a standard workflow's ABORTED transition emits a Step Functions Execution Status Change event to the default EventBridge bus | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_StopExecution.html) | ### Tags | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `TagResource` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_TagResource.html) | | `UntagResource` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_UntagResource.html) | | `ListTagsForResource` | ✅ Supported | | [docs](https://docs.aws.amazon.com/step-functions/latest/apireference/API_ListTagsForResource.html) | ## Related - [Step Functions](/docs/services/stepfunctions/index.md) — quick start, what works, and the differences from AWS - [All service pages](/docs/services/index.md)
