.. py:method:: Organizations.Client.list_organizational_units_for_parent(**kwargs)

  

  Lists the organizational units (OUs) in a parent organizational unit or root.

   

  .. note::

    

    When calling List* operations, always check the ``NextToken`` response parameter value, even if you receive an empty result set. These operations can occasionally return an empty set of results even when more results are available. Continue making requests until ``NextToken`` returns null. A null ``NextToken`` value indicates that you have retrieved all available results.

    

   

  You can only call this operation from the management account or a member account that is a delegated administrator.

  **Request Syntax**
  ::

    response = client.list_organizational_units_for_parent(
        ParentId='string',
        NextToken='string',
        MaxResults=123
    )
    
  :type ParentId: string
  :param ParentId: **[REQUIRED]** 

    ID for the root or OU whose child OUs you want to list.

     

    The `regex pattern <http://wikipedia.org/wiki/regex>`__ 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.
    

    

  
  :type NextToken: string
  :param NextToken: 

    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.

    

  
  :type MaxResults: integer
  :param MaxResults: 

    The maximum number of items to return in the response. If more results exist than the specified ``MaxResults`` value, a token is included in the response so that you can retrieve the remaining results.

    ::

      {
          'OrganizationalUnits': [
              {
                  'Id': 'string',
                  'Arn': 'string',
                  'Name': 'string'

    **Response Structure**

    

    - *(dict) --* 
      

      - **OrganizationalUnits** *(list) --* 

        A list of the OUs in the specified root or parent OU.

        
        

        - *(dict) --* 

          Contains details about an organizational unit (OU). An OU is a container of Amazon Web Services accounts within a root of an organization. Policies that are attached to an OU apply to all accounts contained in that OU and in any child OUs.

          
          

          - **Id** *(string) --* 

            The unique identifier (ID) associated with this OU. The ID is unique to the organization only.

             

            The `regex pattern <http://wikipedia.org/wiki/regex>`__ for an organizational unit ID string requires "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.

            
          

          - **Arn** *(string) --* 

            The Amazon Resource Name (ARN) of this OU.

             

            For more information about ARNs in Organizations, see `ARN Formats Supported by Organizations <https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsorganizations.html#awsorganizations-resources-for-iam-policies>`__ in the *Amazon Web Services Service Authorization Reference*.

            
          

          - **Name** *(string) --* 

            The friendly name of this OU.

             

            The `regex pattern <http://wikipedia.org/wiki/regex>`__ that is used to validate this parameter is a string of any of the characters in the ASCII character range.

            
      
    
      

      - **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``.

        
  
  **Exceptions**
  
  *   :py:class:`Organizations.Client.exceptions.AccessDeniedException`

  
  *   :py:class:`Organizations.Client.exceptions.AWSOrganizationsNotInUseException`
