# DT FairBid (Open Beta) This topic explains how to set up the DT Fairbid bidding mediation partner for Audience Network. ## Before You Start - **Audience Network SDK requirements:** 6.2.1 or later ([Android](https://developers.facebook.com/documentation/audience-network/setting-up/platform-setup/android/add-sdk) \| [iOS](https://developers.facebook.com/documentation/audience-network/setting-up/platform-setup/ios/add-sdk)) - **Supported formats:** Banner, Interstitial, Rewarded video ## How to Set Up Bidding If you are new to Audience Network, follow [these steps from DT Fairbid](https://developer.fyber.com/hc/en-us/articles/360010170518-Facebook). See DT Fairbid’s technical guidance on how to set up for [DT Fairbid](https://developer.fyber.com/hc/en-us/categories/360001778457-Fyber-FairBid). Audience Network’s bidding product is currently operated as an open beta program and there is no approval needed on the Meta Audience Network side. ### Setting up bidding placements through Monetization Manager - Rewarded video, interstitial and banner placements cannot be mixed. They should be configured as separate placements (waterfall or bidding). - If rewarded video is not available in Monetization Manager, you must obtain rewarded video approval for this directly from the Meta Audience Network team. - We recommend moving the top revenue placement ID when moving from waterfall to bidding. - If you’re wanting to test bidding against waterfall, we recommend running an A/B test between waterfall and bidding, rather than a pre/post test, in order to understand the true value of the solution. A/B tests are best for publishers who want to see a certain percentage of revenue uplift before they make the decision to fully transition to bidding. Since outside variables are less likely to influence the outcome, A/B tests make it easier to learn the amount of revenue attributable to bidding and the overall ARPDAU uplift driven by the different bidders.
