SynchronizeMultiRegionKey

The following example shows an Amazon CloudTrail log entry generated when Amazon KMS synchronizes a multi-Region key. Synchronizing involves cross-Region calls to copy the shared properties of a multi-Region primary key to its replica keys. Amazon KMS synchronizes multi-Region keys periodically to assure that all related multi-Region keys have the same key material.

The resources element of the CloudTrail log entry includes the key ARN of the multi-Region primary key, including its Amazon Web Services Region. The related multi-Region replica keys and their Regions are not listed in this log entry.

CloudTrail log entries for this operation recorded on or after December 2022 include the key ARN of the affected KMS key in the responseElements.keyId value, even though this operation does not return the key ARN.
