In-App OTT header bidding
To support header bidding for OTT mobile apps, OpenWrap supports a REST API that fetches bids for a video ad slot and returns those bids as a set of targeting keys that can be passed to the ad server. The following steps describe how to call this API and send the returned targeting keys to GAM.
Create an OpenWrap profile with Video (VAST) chosen as the Platform type. Then configure bidders, map ad units, and push the profile live. See OpenWrap Profile Management for details on how to create a profile and map ad units.
Step 2: Make a call to OpenWrap ahead of call to ad server to fetch bids.
