VPAID stands for Video Player Ad Interface Definition, a common interface used to deliver interactive video ads to multiple types of video players. The VAST and VPAID specifications were both developed by the IAB, but unlike VAST, which only supports one-way communication, VPAID allows for dynamic two-way communications, enabling the user, the video ad, and the video player to interact, so a rich interactive in-stream ad experience can be delivered.
Users can click on links and buttons in the ad, zoom in/out, fill out forms, play games, share the ad on social media, request more information, etc., and advertisers can collect data on these interactions.
To serve interactive ads, VAST can be used to support the basic delivery and VPAID can be added on top of that to support the interactive features.
