## Registration

If you have any questions regarding set up, please reach out to your Viant account manager: <dist-vps@viantinc.com>.

Please note that Viant Publisher Solutions has transitioned its serving architecture to Prebid Server. The Prebid.js Module is now legacy, and only the Prebid Server integration is active.

To activate an account, publishers must already have an approved Viant Publisher Solutions (VPS) login and an active `publisherId` in order for the adapter to function appropriately.

All other configurations occur within the VPS self-service environment.
