Maybe we already discuss, that we can possibly avoid using "Response" object at most admin client operations. We typically use them in "create" methods (POST requests). So if we refactor server-side to return the actual created object with filled ID, we can use something like: ClientRepresentation createdClient = realmResource.clients().create(clientRepresentation); String createdUuid = createdClient.getId(); instead of current: Response response = realm.clients().create(rep); response.close(); String createdUuid = ApiUtil.getCreatedId(response); The advantages is that: - No need to care about closing response - Better exception handling - instead of checking response status etc, the new code will throw exception directly. Which is usually cleaner - You don't need to send separate GET request to retrieve newly created client. And in most cases, you usually want newly created client The possible disadvantage: - The POST response is bigger as it contains representation of newly created client. However you probably usually need the new client anyway. Not sure if it's possible to set admin console (angular) to avoid sending separate GET request when the entity was already retrieved through POST, but I suppose that yes. Marek
