# 使用 Step Functions 建立和管理 Amazon SageMaker AI 任務
了解如何使用 Step Functions 在 SageMaker AI 上建立和管理任務。此頁面列出支援的 SageMaker AI API 動作，並提供建立 SageMaker AI 轉換、訓練、標記和處理任務的範例`Task`狀態。
若要了解如何在 Step Functions 中整合 AWS服務，請參閱 [整合 服務](integrate-services.md)和 [在 Step Functions 中將參數傳遞至服務 API](connect-parameters.md)。
**Optimized SageMaker AI 整合的主要功能**
支援[執行任務 (.sync)](connect-to-resource.md#connect-sync)整合模式。
[請求回應](connect-to-resource.md#connect-default) 整合模式沒有特定的最佳化。
不支援[使用任務字符等待回呼](connect-to-resource.md#connect-wait-token)整合模式。

## 呼叫 Amazon SageMaker AI 的 IAM 政策
下列範例範本顯示 如何根據狀態機器定義中的資源AWS Step Functions產生 IAM 政策。如需詳細資訊，請參閱[Step Functions 如何為整合服務產生 IAM 政策](service-integration-iam-templates.md)及[探索 Step Functions 中的服務整合模式](connect-to-resource.md)。
**注意**
對於這些範例， `roleArn`是指 SageMaker AI 用來存取模型成品和 Docker 影像的 IAM 角色的 Amazon Resource Name (ARN)，以便在 ML 運算執行個體上部署，或用於批次轉換任務。如需詳細資訊，請參閱 [Amazon SageMaker 角色](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-roles.html)。
