As an Appnext publisher, you will receive a "Direct-Buy" notification, once an advertiser launches a Direct-Buy campaign for one, or all, of your mobile assets.
Please make sure that any of the Appnext tools, SDK, tags or API, are active within your apps or websites. The Appnext ads will start serving the bidding app. The optimization algorithm will give the Direct-Buy campaign the right priority, based on its performance.
