API Reference (API Version 2016-11-28)

ListParents

Lists the root or organizational units (OUs) that serve as the immediate parent of the specified child OU or account. This operation, along with ListChildren enables you to traverse the tree structure that makes up this root.

This operation can be called only from the organization's master account.

Note

In the current release, a child can have only a single parent.

Request Syntax

{
   "ChildId": "string",
   "MaxResults": number,
   "NextToken": "string"
}

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

ChildId

The unique identifier (ID) of the OU or account whose parent containers you want to list. Do not specify a root.

The regex pattern for a child ID string requires one of the following:

  • Account: a string that consists of exactly 12 digits.

  • Organizational unit (OU): a string that begins with "ou-" followed by from 4 to 32 lower-case letters or digits (the ID of the root that contains the OU) followed by a second "-" dash and from 8 to 32 additional lower-case letters or digits.

Type: String

Pattern: ^(\d{12})|(ou-[0-9a-z]{4,32}-[a-z0-9]{8,32})$

Required: Yes

MaxResults

(Optional) Use this to limit the number of results you want included in the response. If you do not include this parameter, it defaults to a value that is specific to the operation. If additional items exist beyond the maximum you specify, the NextToken response element is present and has a value (is not null). Include that value as the NextToken request parameter in the next call to the operation to get the next part of the results. Note that Organizations might return fewer results than the maximum even when there are more results available. You should check NextToken after every operation to ensure that you receive all of the results.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 20.

Required: No

NextToken

Use this parameter if you receive a NextToken response in a previous request that indicates that there is more output available. Set it to the value of the previous call's NextToken response to indicate where the output should continue from.

Type: String

Required: No

Response Syntax

{
   "NextToken": "string",
   "Parents": [ 
      { 
         "Id": "string",
         "Type": "string"
      }
   ]
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

NextToken

If present, this value indicates that there is more output available than is included in the current response. Use this value in the NextToken request parameter in a subsequent call to the operation to get the next part of the output. You should repeat this until the NextToken response element comes back as null.

Type: String

Parents

A list of parents for the specified child account or OU.

Type: Array of Parent objects
