<p> Starts an import of logged trail events from a source S3 bucket to a destination event data store. By default, CloudTrail only imports events contained in the S3 bucket's <code>CloudTrail</code> prefix and the prefixes inside the <code>CloudTrail</code> prefix, and does not check prefixes for other Amazon Web Services services. If you want to import CloudTrail events contained in another prefix, you must include the prefix in the <code>S3LocationUri</code>. For more considerations about importing trail events, see <a href="https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-copy-trail-to-lake.html#cloudtrail-trail-copy-considerations">Considerations</a>. </p> <p> When you start a new import, the <code>Destinations</code> and <code>ImportSource</code> parameters are required. Before starting a new import, disable any access control lists (ACLs) attached to the source S3 bucket. For more information about disabling ACLs, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html">Controlling ownership of objects and disabling ACLs for your bucket</a>. </p> <p> When you retry an import, the <code>ImportID</code> parameter is required. </p> <note> <p> If the destination event data store is for an organization, you must use the management account to import trail events. You cannot use the delegated administrator account for the organization. </p> </note>
