poddedupe 4 means Deduplicated on mediafile URL
Bids whose VAST media file URLs match are treated as the same ad.
When to send it
Send 4 when the seller compares the media file URLs inside the returned VAST and drops duplicates. This catches the same video arriving through different buyers or under different creative IDs, which happens when one campaign runs through several buying platforms.
Bidders cannot fully control this check, because the same media URL can reach the auction through any path. It is confused with 3: creative ID checks what the bidder says, while the media URL checks what will actually play. Sellers that accept wrappers have to resolve the chain before they can compare URLs.
