Request parameters


Parameter	Type	Required	Example	Description
Action	String	Yes	DeleteStackInstances	The operation that you want to perform. Set the value to DeleteStackInstances.
RegionId	String	Yes	cn-hangzhou	The region ID of the stack group. You can call the DescribeRegions operation to query the most recent region list.
StackGroupName	String	Yes	MyStackGroup	The name of the stack group. The name must be unique within a region. The name can be up to 255 characters in length and can contain digits, letters, hyphens (-), and underscores (_). It must start with a digit or letter.
AccountIds	Array of String	No	["151266687691**","141261387191**"]	The IDs of the accounts in which the stacks contained in the stack group are granted with self-managed permissions. You can specify a maximum of 20 account IDs.
RegionIds	Array of String	Yes	["cn-hangzhou","cn-beijing"]	The region IDs of the stack instances. You can specify a maximum of 20 region IDs.
RetainStacks	Boolean	Yes	false	Specifies whether to retain the relevant stacks when you delete the stack instances from the stack group. Valid values: true: The stacks are retained. false: The stacks are deleted.
ClientToken	String	No	123e4567-e89b-12d3-a456-42665544****	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The token can be up to 64 characters in length and can contain letters, digits, hyphens (-), and underscores (_). For more information, see Ensure idempotence.
OperationDescription	String	No	Delete stack instances in hangzhou and beijing	The description of the deletion operation. The description must be 1 to 256 characters in length.
OperationPreferences	Map	No	{"FailureToleranceCount": 1, "MaxConcurrentCount": 2}	The parameters that you configure to delete the stack instances. Valid values: {"FailureToleranceCount": N} The maximum number of stack operation failures that can occur within the accounts in each region. When the value is exceeded, the operation fails to be performed in the region. If the operation fails to be performed in one region, the operation fails to be performed in other regions. Valid values of N: 0 to 20. Default value: 0. If you do not specify the FailureToleranceCount parameter, the default value 0 is used. {"FailureTolerancePercentage": N} The percentage of the total number of accounts within which stack operation failures can occur to the total number of accounts in each region. When the value is exceeded, the operation fails to be performed in the region. Valid values of N: 0 to 100. Default value: 0. If the numeric value in the percentage is not an integer, Resource Orchestration Service (ROS) rounds the number down to the nearest integer. If you do not specify the FailureTolerancePercentage parameter, the default value 0 is used. {"MaxConcurrentCount": N} The maximum number of accounts in which operations are performed on stacks concurrently in each region. Valid values of N: 1 to 20. Default value: 1. If you do not specify the MaxConcurrentCount parameter, the default value 1 is used. {"MaxConcurrentPercentage": N} The percentage of the total number of accounts in which operations are performed on stacks concurrently to the total number of accounts in each region. Valid values of N: 1 to 100. Default value: 1. If the numeric value in the percentage is not an integer, ROS rounds the number down to the nearest integer. If you do not specify the MaxConcurrentPercentage parameter, the default value 1 is used. Separate multiple parameters with commas (,). Note You can specify only one of the MaxConcurrentCount and MaxConcurrentPercentage parameters. You can specify only one of the FailureToleranceCount and FailureTolerancePercentage parameters.
DeploymentTargets	Object	No		The folders in which you want to deploy the stacks granted with service-managed permissions.
RdFolderIds	Array of String	Yes	["fd-4PvlVLOL8v"]	The folder IDs of the resource directory. You can add a maximum of five folder IDs. You can create stack instances in all the member accounts that are contained in the specified folders. If you create stack instances in the Root folder, the stack instances are created in all the member accounts in the resource directory. Note To view the folder IDs, go to the overview page in the Resource Management console. For more information, see View the basic information of a folder.
