# ListStackInstanceResourceDrifts
Returns drift information for resources in a stack instance.
**Note**
`ListStackInstanceResourceDrifts` returns drift information for the most recent drift detection operation. If an operation is in progress, it may only return partial results.
## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
** CallAs **
[Service-managed permissions] Specifies whether you are acting as an account administrator in the organization's management account or as a delegated administrator in a member account.

+ If you are signed in to a delegated administrator account, specify `DELEGATED_ADMIN`.
Your AWS account must be registered as a delegated administrator in the management account. For more information, see [Register a delegated administrator](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-orgs-delegated-admin.html) in the * AWS CloudFormation User Guide*.
Type: String

Required: No
** NextToken **
The token for the next set of items to return. (You received this token from a previous call.)
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
Required: No
** OperationId **
The unique ID of the drift operation.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern: `[a-zA-Z0-9][-a-zA-Z0-9]*`
Required: Yes
** StackInstanceAccount **
The name of the AWS account that you want to list resource drifts for.
Type: String
Pattern: `^[0-9]{12}$`
Required: Yes
** StackInstanceRegion **
The name of the Region where you want to list resource drifts.
Type: String
Pattern: `^[a-zA-Z0-9-]{1,128}$`
Required: Yes
**StackInstanceResourceDriftStatuses.member.N**
The resource drift status of the stack instance.
+ `DELETED`: The resource differs from its expected template configuration in that the resource has been deleted.
+ `MODIFIED`: One or more resource properties differ from their expected template values.
+ `IN_SYNC`: The resource's actual configuration matches its expected template configuration.
+ `NOT_CHECKED`: CloudFormation doesn't currently return this value.
Type: Array of strings
Array Members: Minimum number of 1 item. Maximum number of 4 items.
Valid Values: `IN_SYNC | MODIFIED | DELETED | NOT_CHECKED | UNKNOWN | UNSUPPORTED`
Required: No
** StackSetName **
The name or unique ID of the StackSet that you want to list drifted resources for.
Type: String
Pattern: `[a-zA-Z][-a-zA-Z0-9]*(?::[a-zA-Z0-9]{8}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{12})?`
Required: Yes
## Response Elements
The following elements are returned by the service.
** NextToken **
If the previous paginated request didn't return all of the remaining results, the response object's `NextToken` parameter value is set to a token. To retrieve the next set of results, call this action again and assign that token to the request object's `NextToken` parameter. If there are no remaining results, the previous response object's `NextToken` parameter is set to `null`.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
**Summaries.member.N**
A list of `StackInstanceResourceDriftsSummary` structures that contain information about the specified stack instances.
Type: Array of [StackInstanceResourceDriftsSummary](API_StackInstanceResourceDriftsSummary.md) objects
