How do I signal rewarded inventory in OpenRTB?

Answer

Set imp.rwdd = 1. The field was added in OpenRTB 2.6, is an integer with default 0, and means the user receives a reward for viewing the ad: an extra life in a game, a free article, or an ad-free music session, typically granted after the video completes. Before 2.6 this signal lived in assorted imp.ext extensions, so if you support older partners you may need to dual-write. rwdd sits on the impression, not on the video object, so it applies to any media type offered in that imp.
