Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the stack group. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou

StackInstanceAccountId	string	No	The ID of the destination account to which the stack belongs. If the stack group is granted self-managed permissions, the stack belongs to an Alibaba Cloud account. If the stack group is granted service-managed permissions, the stack belongs to a member in a resource directory. Note For more information about the destination account, see Overview .	156552876021****
StackInstanceRegionId	string	No	The region ID of the stack.	cn-beijing
PageSize	long	No	The number of entries to return on each page. Valid values: 1 to 50. Default value: 10.	10

Response parameters

Parameter	Type	Description	Example
	object

	object
Status	string	The state of the stack. Valid values: CURRENT: The stack is up-to-date with the stack group. OUTDATED: The stack is not up-to-date with the stack group.

The creation or update operation is not complete.	CURRENT
StackGroupId	string	The ID of the stack group.	fd0ddef9-9540-4b42-a464-94f77835****
StackId	string	The stack ID. Note This parameter is returned only if the stack is in the CURRENT state.	35ad60e3-6a92-42d8-8812-f0700d45****
DriftDetectionTime	string	The time when the last successful drift detection was performed on the stack. Note This parameter is returned only if drift detection is performed on the stack group.	2020-02-27T07:47:47
StackDriftStatus	string	The state of the stack when the last successful drift detection was performed on the stack group. Valid values: DRIFTED: The stack has drifted. NOT_CHECKED: No successful drift detection is performed on the stack. IN_SYNC: The stack is being synchronized. Note This parameter is returned only if drift detection is performed on the stack group.	IN_SYNC
StatusReason	string	The reason why the stack instance is in the OUTDATED state. Note This parameter is returned only if the stack instance is in the OUTDATED state.	User initiated stop
StackGroupName	string	The name of the stack group.	MyStackGroup
AccountId	string	The ID of the destination account to which the stack belongs.	156552876021****
