Amazon S3 - How to Set Permissions on Versioned Object (PUT Object ACL on Object Version)?

To grant access on S3 Version object , you can set access control list (ACL) permissions for the object stored in Amazon S3 Bucket using PUT Object ACL REST API. You can set the ACL of an object on the object version level. PUT Object ACL request sets the ACL of the latest version of an object. You can use versionID subresource to be able to set the ACL of a different version.
To authenticate the request, you need to have WRITE_ACP permission.
