    post:
      operationId: AssociateAccounts
      summary: Associate Accounts
      description: Associates one or more member accounts with your organization's management account, enabling centralized
        implementation of optimization actions across those accounts. Once associated, the management account (or a delegated
        administrator) can apply recommended actions to the member account. When you associate a member account, its organization
        rule mode is automatically set to "Any allowed," which permits the management account to create Automation rules that
        automatically apply actions to that account. If the member account has not previously enabled the Automation feature,
        the association process automatically enables it. Only the management account or a delegated administrator can perform
        this action.
