# Actions supported by Object Storage roles

Actions available to Object Storage users with specific [roles](/iam/authorization/roles) are based on the [Amazon S3 API methods](https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations_Amazon_Simple_Storage_Service.html).

## Available actions per role

Object Storage roles support the following actions:

Note that the `CopyObject` and `UploadPartCopy` actions require roles that have both Download and Upload [permissions](/iam/authorization/roles#object-storage).

> For example, to be able to copy an object, the user needs to have one of the following roles or combinations of roles:
>
> * `storage.viewer` + `storage.uploader`
> * `storage.object-viewer` + `storage.uploader`
> * `storage.editor`
> * `storage.object-editor`
