This guide shows you how to integrate a mediation adapter with your current iOS app and set up additional request parameters.


Before you can integrate mediation for an ad format, you need to integrate that ad format into your app:

Know which ad network wins

Each ad format class has a GADResponseInfo property that contains adNetworkClassName which returns the class name of the ad network for the current ad. adNetworkClassName only has a value once an ad successfully loads. The code below shows you how to get that information for banner ads.


func adViewDidReceiveAd(_ bannerView: GAMBannerView) {
  print("Banner adapter class name: \(bannerView.responseInfo.adNetworkClassName)")


- (void)adViewDidReceiveAd:(GAMBannerView *)bannerView {
  NSLog(@"Banner adapter class name: %@", bannerView.responseInfo.adNetworkClassName);

Refer to Retrieving Information about the Ad Response for details.

Make sure to disable refresh in all third-party ad networks UI for banner ad units used in Ad Manager mediation. This will prevent a double refresh since Ad Manager also triggers a refresh based on your banner ad unit's refresh rate.

Rewarded ads mediation

We recommend that you override all default reward values by setting reward values in the Ad Manager UI. To do this, select the Override reward settings from third-party ad networks when using mediation box so that the reward is consistent across all networks. Some ad networks don't provide a reward value or type at all. By overriding the reward value, the reward is consistent no matter which ad network served the ad.

Refer to set up and traffic rewarded ads for apps for more information.

Native ads mediation

The following are some best practices to consider when implementing native mediation.

Native ad presentation policy
Each ad network has its own policies. When using mediation, it's important to remember that your app still needs to abide by the policies of the mediated network that provided the ad.
Avoid using the GADMultipleAdsAdLoaderOptions class when making requests
Requests for multiple native ads only serve Google ads. The multiple native ads feature does not support mediation.


If you need to comply with the California Consumer Privacy Act (CCPA) or General Data Protection Regulation (GDPR), follow the steps in CCPA settings or GDPR settings to add your mediation partners in Ad Manager Privacy & messaging's CCPA or GDPR ad partners list. Failure to do so can lead to partners failing to serve ads on your app.
