Retrieving Information about the Ad Response

For debugging and logging purposes, successfully loaded ads provide a GADResponseInfo object. This object contains information about the ad it loaded, in addition to information about the mediation waterfall used to load the ad.

For cases where an ad loads successfully, the ad object has a GADResponseInfo property. For example, GADInterstitialAd.responseInfo gets the response info for a loaded interstitial ad.

For cases where ads fail to load and only an error is available, the GADResponseInfo is available using the key GADErrorUserInfoKeyResponseInfo on the error's userInfo dictionary.

Swift

fileprivate func loadInterstitial() {
  GADInterstitialAd.load(
    withAdUnitID: "/6499/example/interstitial", request: request
  ) { (ad, error) in
    if let error = error {
      let responseInfo = (error as NSError).userInfo[GADErrorUserInfoKeyResponseInfo] as? GADResponseInfo
      print("\(String(describing: responseInfo))")
      return
    }
    let responseInfo = ad?.responseInfo
    print("\(String(describing: responseInfo))")
  }
}

Objective-C

- (void)loadInterstitial {
  [GADInterstitialAd
   loadWithAdUnitID:@"/6499/example/interstitial"
   request:request
   completionHandler:^(GADInterstitialAd *ad, NSError *error) {
    if (error) {
      GADResponseInfo *responseInfo = error.userInfo[GADErrorUserInfoKeyResponseInfo];
      NSLog(@"%@", responseInfo.description);
      return;
    }
    GADResponseInfo *responseInfo = ad.responseInfo;
    NSLog(@"%@", responseInfo.description);
  }];
}

Response info

Here is a sample output showing the debugging data returned for a loaded ad:

Properties on GADResponseInfo include:

Property	Description
`adNetworkInfoArray`	Returns the list of `GADAdNetworkResponseInfo` containing metadata for each adapter included in the ad response. Can be used to debug the waterfall mediation and bidding execution. The order of the list matches the order of the mediation waterfall for this ad request. See Adapter Response Info for more information.
`loadedAdNetworkResponseInfo`	Returns the `GADAdNetworkResponseInfo` corresponding to the adapter that loaded the ad.
`adNetworkClassName`	Returns the mediation adapter class name of the ad network that loaded the ad.
`responseIdentifier`	The response identifier is a unique identifier for the ad response. This identifier can be used to identify and block the ad in the Ads Review Center (ARC).
`extrasDictionary`	Beta: This API is in beta. Returned values can change without an SDK release. Returns extra information about the ad response.

Swift

fileprivate func loadInterstitial() {
  GADInterstitialAd.load(
    withAdUnitID: "/6499/example/interstitial", request: request
  ) { (ad, error) in
    let responseInfo = ad?.responseInfo

    let responseIdentifier = responseInfo?.responseIdentifier
    let adNetworkClassName = responseInfo?.adNetworkClassName
    let adNetworkInfoArray = responseInfo?.adNetworkInfoArray
    let loadedAdNetworkResponseInfo = responseInfo?.loadedAdNetworkResponseInfo
  }
}

Objective-C

- (void)loadInterstitial {
  [GADInterstitialAd
   loadWithAdUnitID:@"/6499/example/interstitial"
   request:request
   completionHandler:^(GADInterstitialAd *ad, NSError *error) {
    GADResponseInfo *responseInfo = ad.responseInfo;

    NSString *responseIdentifier = responseInfo.responseIdentifier;
    NSString *adNetworkClassName = responseInfo.adNetworkClassName;
    NSArray *adNetworkInfoArray = responseInfo.adNetworkInfoArray;
    GADAdNetworkResponseInfo *loadedAdNetworkResponseInfo = responseInfo.loadedAdNetworkResponseInfo;
  }];
}

Adapter Response Info

GADAdNetworkResponseInfo contains metadata for each adapter included in the ad response which can be used to debug the waterfall mediation and bidding execution. The order of the list matches the order of the mediation waterfall for the ad request.

Here is sample GADAdNetworkResponseInfo output:

(    Network: GADMAdapterGoogleAdMobAds
    Ad Source Name:Reservation campaign
    Ad Source ID:7068401028668408324
    Ad Source Instance Name:[DO NOT EDIT] Publisher Test Interstitial
    Ad Source Instance ID:[DO NOT EDIT] Publisher Test Interstitial
    AdUnitMapping:
{
}
    Error: (null)
    Latency: 0.277
)

For each ad network, GADAdNetworkResponseInfo provides the following properties:

Property	Description
`error`	The error associated with the request to the network. Returns `nil` if the network successfully loaded an ad or if the network was not attempted.
`adSourceId`	The ad source ID associated with this adapter response.
`adSourceInstanceId`	The ad source instance ID associated with this adapter response.
`adSourceInstanceName`	The ad source instance name associated with this adapter response.
`adSourceName`	The ad source representing the specific ad network that serves the impression.
`adNetworkClassName`	The class name of the ad network adapter that loaded the ad.
`adUnitMapping`	The network configuration set from the Ad Manager UI.
`latency`	The amount of time the ad network spent loading an ad. Returns `0` if the network was not attempted.

Swift

fileprivate func loadInterstitial() {
  GADInterstitialAd.load(
    withAdUnitID: "/6499/example/interstitial", request: request
  ) { (ad, error) in
    let responseInfo = ad?.responseInfo
    let loadedAdNetworkResponseInfo = responseInfo?.loadedAdNetworkResponseInfo

    let adNetworkError = loadedAdNetworkResponseInfo?.error
    let adSourceId = loadedAdNetworkResponseInfo?.adSourceID
    let adSourceInstanceId = loadedAdNetworkResponseInfo?.adSourceInstanceID
    let adSourceInstanceName = loadedAdNetworkResponseInfo?.adSourceInstanceName
    let adSourceName = loadedAdNetworkResponseInfo?.adSourceName
    let adNetworkClassName = loadedAdNetworkResponseInfo?.adNetworkClassName
    let adUnitMapping = loadedAdNetworkResponseInfo?.adUnitMapping
    let latency = loadedAdNetworkResponseInfo?.latency
  }
}

Objective-C

- (void)loadInterstitial {
  [GADInterstitialAd
   loadWithAdUnitID:@"/6499/example/interstitial"
   request:request
   completionHandler:^(GADInterstitialAd *ad, NSError *error) {
    GADResponseInfo *responseInfo = ad.responseInfo;
    GADAdNetworkResponseInfo *loadedAdNetworkResponseInfo = responseInfo.loadedAdNetworkResponseInfo;

    NSError *adNetworkError = loadedAdNetworkResponseInfo.error;
    NSString *adSourceId = loadedAdNetworkResponseInfo.adSourceID;
    NSString *adSourceInstanceId = loadedAdNetworkResponseInfo.adSourceInstanceID;
    NSString *adSourceInstanceName = loadedAdNetworkResponseInfo.adSourceInstanceName;
    NSString *adSourceName = loadedAdNetworkResponseInfo.adSourceName;
    NSString *adNetworkClassName = loadedAdNetworkResponseInfo.adNetworkClassName;
    NSDictionary *adUnitMapping = loadedAdNetworkResponseInfo.adUnitMapping;
    NSTimeInterval latency = loadedAdNetworkResponseInfo.latency;
