<p>Creates and updates the configuration aggregator with the selected source accounts and regions. The source account can be individual account(s) or an organization.</p> <p> <code>accountIds</code> that are passed will be replaced with existing accounts. If you want to add additional accounts into the aggregator, call <code>DescribeConfigurationAggregators</code> to get the previous accounts and then append new ones.</p> <note> <p>Config should be enabled in source accounts and regions you want to aggregate.</p> <p>If your source type is an organization, you must be signed in to the management account or a registered delegated administrator and all the features must be enabled in your organization. If the caller is a management account, Config calls <code>EnableAwsServiceAccess</code> API to enable integration between Config and Organizations. If the caller is a registered delegated administrator, Config calls <code>ListDelegatedAdministrators</code> API to verify whether the caller is a valid delegated administrator.</p> <p>To register a delegated administrator, see <a href="https://docs.aws.amazon.com/config/latest/developerguide/set-up-aggregator-cli.html#register-a-delegated-administrator-cli">Register a Delegated Administrator</a> in the <i>Config developer guide</i>. </p> </note> <note> <p> <code>PutConfigurationAggregator</code> is an idempotent API. Subsequent requests won’t create a duplicate resource if one was already created. If a following request has different <code>tags</code> values, Config will ignore these differences and treat it as an idempotent request of the previous. In this case, <code>tags</code> will not be updated, even if they are different.</p> </note>
