@vineela1999 The response already has a <Owner></Owner> tag.
This tag refers to the owner of the buckets.
Now if a tenantId is returned as part of the bucket metadata will this <Owner> tag still be returned?

[vineela1999]

@anvithks OwnerID here is used in the sense who requested for list buckets and each tenantId is who created the bucket

@vineela1999 Owner in response to a GET buckets call will mean the owner of the bucket.
In the current API it refers to the owner of the bucket as the API does not return the ownerID per bucket but for all buckets.
