The following page discusses the Cloud Identity and Access Management (Cloud IAM) permissions required to perform various actions on Cloud Storage buckets and objects when using the GCP Console.
Common permissions required for using the GCP Console
Certain permissions are broadly necessary in order to use the GCP Console:
All actions involving buckets require
resourcemanager.projects.getandstorage.buckets.listpermissions at the project level.These permissions allow you to access the buckets page of the Console Browser where you create, view, and update buckets.
All actions involving objects require
storage.objects.listpermission at the project or bucket level.This permission allows you to access object pages of the Console Browser where you upload, view, and modify objects.
All actions that include a billing project in the request require
serviceusage.services.usepermission for the project that's specified.This permissions ensures you are authorized to bill the project you specify. Including a billing project is used, for example, when accessing a bucket with Requester Pays enabled.

1This permission is only required when the copied/moved object has the same name as an object that already exists in the bucket.
2This permission is only required when keeping the permissions currently applied to the source object.
3This permission is only required if you do not include a billing project in your request. See Requester Pays Use and access requirements for more information.
