Hello @patmmccann, please find our PR related to the discussion we had on #6611 to support Prebid 5.x

• Our adapter supports two video parameters (the rest is handled server-side) and you will notice that we convert the oRTB values to our bidder-specific values (one day I really need to convert our values to the standard ones ahah)
• we support return advertiserDomains yet, but we provided the placeholder to be compatible with Prebid 5

Thanks!

Thanks so much for this, we really appreciate the quick turn around as we're hoping to release 5 on Wednesday!
