SendWorkflowStepActionRequest

The action to perform on the paused workflow step. RESUME completes the waiting step, and the workflow continues. STOP fails the step, and the step's onFailure setting determines whether the workflow continues or aborts. The workflow step must be in a waiting state to accept an action. The request fails if the step has already timed out or been actioned.

A unique, case-sensitive identifier you provide to ensure that the operation runs no more than one time. If you retry a request with the same client token, Image Builder returns the original response without running the operation again. For more information, see Ensuring idempotency in the Amazon EC2 API Reference.

The Amazon Resource Name (ARN) of the image build version associated with the workflow step execution. This value must match the image that owns the waiting step. If the ARN does not correspond to the image running the workflow, then the request fails with a validation error.

The reason for the action. This value is stored with the step execution record and is accessible in subsequent workflow steps via step output references.

Uniquely identifies the waiting workflow step that you send the action to. To get this identifier, call ListWaitingWorkflowSteps.
