Organizations / Client / list_children

list_children#

Organizations.Client.list_children(**kwargs)#

Lists all of the organizational units (OUs) or accounts that are contained in the specified parent OU or root. This operation, along with ListParents enables you to traverse the tree structure that makes up this root.

Note

Always check the NextToken response parameter for a null value when calling a List* operation. These operations can occasionally return an empty set of results even when there are more results available. The NextToken response parameter value is null only when there are no more results to display.

This operation can be called only from the organization’s management account or by a member account that is a delegated administrator for an Amazon Web Services service.

Request Syntax

response = client.list_children(
    ParentId='string',
    ChildType='ACCOUNT'|'ORGANIZATIONAL_UNIT',
    NextToken='string',
    MaxResults=123
)
Parameters:

  • ParentId (string) –

    [REQUIRED]

    The unique identifier (ID) for the parent root or OU whose children you want to list.

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

    • Root - A string that begins with “r-” followed by from 4 to 32 lowercase letters or digits.

    • Organizational unit (OU) - A string that begins with “ou-” followed by from 4 to 32 lowercase letters or digits (the ID of the root that the OU is in). This string is followed by a second “-” dash and from 8 to 32 additional lowercase letters or digits.

  • ChildType (string) –

    [REQUIRED]

    Filters the output to include only the specified child type.

  • NextToken (string) – The parameter for receiving additional results if you receive a NextToken response in a previous request. A NextToken response indicates that more output is available. Set this parameter to the value of the previous call’s NextToken response to indicate where the output should continue from.

  • MaxResults (integer) – The total number of results that you want included on each page of 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.

Return type:

dict

Response Syntax

{
    'Children': [
        {
            'Id': 'string',
            'Type': 'ACCOUNT'|'ORGANIZATIONAL_UNIT'
        },
    ],
    'NextToken': 'string'
}

Response Structure

  • (dict) –

    • Children (list) –

      The list of children of the specified parent container.

      • (dict) –

        Contains a list of child entities, either OUs or accounts.

        • Id (string) –

          The unique identifier (ID) of this child entity.

          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 lowercase letters or digits (the ID of the root that contains the OU). This string is followed by a second “-” dash and from 8 to 32 additional lowercase letters or digits.

        • Type (string) –

          The type of this child entity.

    • NextToken (string) –

      If present, indicates that more output is 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.

Examples

The following example shows how to request a list of the child OUs in a parent root or OU:/n/n

response = client.list_children(
    ChildType='ORGANIZATIONAL_UNIT',
    ParentId='ou-examplerootid111-exampleouid111',
)

print(response)

Expected Output:

{
    'Children': [
        {
            'Id': 'ou-examplerootid111-exampleouid111',
            'Type': 'ORGANIZATIONAL_UNIT',
        },
        {
            'Id': 'ou-examplerootid111-exampleouid222',
