This method uses GET to retrieve all creatives that are part of an account (seat id) belonging to the requesting DSP.
Note: The response code samples below include sellerid. However, there is a use case in which the sellerid is not returned.
A response code that does not include sellerid receives approval on behalf of the seller from the global approvals network. So, the seller network is still the ultimate approver.
Only one network ID providing approval is included in any response's audit status object.
