# DeleteScalingPolicy Deletes the specified scaling policy for an Application Auto Scaling scalable target. Deleting a step scaling policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action. For more information, see [Delete a step scaling policy](https://docs.aws.amazon.com/autoscaling/application/userguide/create-step-scaling-policy-cli.html#delete-step-scaling-policy) and [Delete a target tracking scaling policy](https://docs.aws.amazon.com/autoscaling/application/userguide/create-target-tracking-policy-cli.html#delete-target-tracking-policy) in the *Application Auto Scaling User Guide*. ## Request Syntax ``` { "PolicyName": "string", "ResourceId": "string", "ScalableDimension": "string", "ServiceNamespace": "string" } ``` ## Request Parameters For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

HTTP Status Code: 400 ** InternalServiceException ** The service encountered an internal error. HTTP Status Code: 400 ** ObjectNotFoundException ** The specified object could not be found. For any operation that depends on the existence of a scalable target, this exception is thrown if the scalable target with the specified service namespace, resource ID, and scalable dimension does not exist. For any operation that deletes or deregisters a resource, this exception is thrown if the resource cannot be found. HTTP Status Code: 400 ** ValidationException ** An exception was thrown for a validation issue. Review the available parameters for the API request. HTTP Status Code: 400 ## Examples If you plan to create requests manually, you must replace the Authorization header contents in the examples (`AUTHPARAMS`) with a signature. For more information, see [Signing AWS API requests](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-signing.html) in the *IAM User Guide*. If you plan to use the [AWS CLI](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/), these tools sign the requests for you. ### Example The following example deletes a scaling policy for the Amazon ECS service `web-app` running in the `default` cluster. #### Sample Request ``` POST / HTTP/1.1 Host: application-autoscaling.us-west-2.amazonaws.com Accept-Encoding: identity Content-Length: [content-length] X-Amz-Target: AnyScaleFrontendService.DeleteScalingPolicy X-Amz-Date: 20190506T205712Z User-Agent: aws-cli/1.10.23 Python/2.7.11 Darwin/15.4.0 botocore/1.4.8 Content-Type: application/x-amz-json-1.1 Authorization: AUTHPARAMS { "PolicyName": "my-scale-out-policy", "ServiceNamespace": "ecs", "ScalableDimension": "ecs:service:DesiredCount", "ResourceId": "service/my-cluster/my-service" } ``` ## See Also For more information about using this API in one of the language-specific AWS SDKs, see the following: + [AWS Command Line Interface V2](https://docs.aws.amazon.com/goto/cli2/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for .NET V4](https://docs.aws.amazon.com/goto/DotNetSDKV4/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for C\$1\$1](https://docs.aws.amazon.com/goto/SdkForCpp/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for Go v2](https://docs.aws.amazon.com/goto/SdkForGoV2/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for Java V2](https://docs.aws.amazon.com/goto/SdkForJavaV2/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for JavaScript V3](https://docs.aws.amazon.com/goto/SdkForJavaScriptV3/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for Kotlin](https://docs.aws.amazon.com/goto/SdkForKotlin/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for PHP V3](https://docs.aws.amazon.com/goto/SdkForPHPV3/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for Python](https://docs.aws.amazon.com/goto/boto3/application-autoscaling-2016-02-06/DeleteScalingPolicy) + [AWS SDK for Ruby V3](https://docs.aws.amazon.com/goto/SdkForRubyV3/application-autoscaling-2016-02-06/DeleteScalingPolicy)
