Is there a way to see which IAM did a modification on a aws s3 bucket object (with versioning enabled)?

I know that there is the aws s3api list-object-versions, but it only shows the owner's DisplayName and ID (owner of aws organisation), not the underlying IAM that performed the modification.

"Owner": {
    "DisplayName": "my-username",
    "ID": "7009a8971cd660687538875e7c86c5b672fe116bd438f46db45460ddcd036c32"

Thanks in advance for the help.


You want to configure CloudTrail. This service monitors calls to the AWS platform and can also monitor S3 API calls, logging the user information you require.
