Integrating Facebook Audience Network with Mediation

This guide is intended for publishers who want to use the Google Mobile Ads SDK to load and display ads from the Facebook Audience Network through Open Bidding and waterfall mediation. It covers how to add Facebook Audience Network ads to an ad unit's mediation configuration and how to integrate the Facebook Audience Network SDK and adapter into an iOS app.

Supported ad formats and features

The AdMob mediation adapter for the Facebook Audience Network has the following capabilities:

Formats
Banner
Interstitial
Rewarded
Native
Features
Adaptive banner
Ad network optimization (ANO)
Open Bidding	^1

¹ Open Bidding is currently in a limited beta. Please reach out to your account manager for more information.

Requirements

• iOS deployment target of 9.0 or higher

• [For Open Bidding]: Facebook Audience Network adapter 5.10.0.0 or higher (latest version recommended)

• The latest Facebook Audience Network SDK usually requires the latest version of Xcode

• Latest Google Mobile Ads SDK

Step 1: Set up Facebook Audience Network

Sign up and Log in to the Business Manager Start page.

Click Create a new Business Manager account and fill out the required fields with your business details.

Create a Facebook property

Once you've filled out the required information, you'll be prompted to create a property for your app. Enter the desired name of the property for your app and click Go to Monetization Manager.

Next, select iOS as the platform to monetize.

Indicate whether or not your app is live and click Submit.

You will be prompted to create an ad placement for your application. Select a format, fill out the form and click Next.

Open Bidding

Key Point: Select Banner for all banner sizes, including for 300x250. Facebook does not support the Medium Rectangle display format in open bidding, but does support a flexible width banner with a height of 50, 90, or 250 when using the Banner display format.

Waterfall

Key Point: Select the Medium Rectangle display format if you plan to request 300x250, or Banner display format for all other sizes.

The next step presents an overview of the placement you created. Take note of the Placement ID under the Add placement ID section. Additionally, you will also need your System User Access Token. Simply click the Generate Token button under the Add system user access token section to generate it. You will need both the Placement ID and the System User Access Token when you set up your ad unit ID.

Note: You only need to generate one token. You can use this token across multiple properties and apps in the AdMob UI once it is created. If you are an existing publisher on Facebook Audience Network and need to generate a new token for your property, follow Facebook’s System User Token generation guide.

Step 2: Configure mediation settings for your AdMob ad unit

You need to add Facebook to the mediation configuration for your ad unit. First sign in to your AdMob account.

Navigate to the Mediation tab. If you have an existing mediation group you'd like to modify, click the name of that mediation group to edit it, and skip ahead to Add Facebook Audience Network as an ad source.

To create a new mediation group, select Create Mediation Group.

Enter your ad format and platform, then click Continue.

Give your mediation group a name, and select locations to target. Next, set the mediation group status to Enabled. Then click Add Ad Units, which will open up the ad unit selection overlay.

Associate this mediation group with your existing AdMob ad unit. Then click Done.

You should now see the ad units card populated with the ad units you selected.

Add Facebook Audience Network as an ad source

Open Bidding

In the Ad Sources card, select Add Ad Network. Select Facebook Audience Network (Open Bidding). Enter the Placement ID obtained in the previous section and click Done.

Finally, click Save.

Waterfall

In the Ad Sources card, select Add Ad Network.

Select Facebook Audience Network. Enable the Optimize switch. Enter the System User Access Token and Property ID obtained in the previous section. App Access Token is deprecated and can be left blank. Review and check the Authorization checkbox to set up Ad Network Optimization (ANO) for Facebook Audience Network. Then enter an eCPM value for Facebook Audience Network and click Continue.

Enter the Placement ID obtained in the previous section. Then click Done.

Finally, click Save.

Note: Ad network optimization takes a few days to gather data to accurately calculate eCPM for a mediation network. In the meantime, the ANO status will be PENDING, so you must manually set an eCPM value for the network. Once the eCPM can be calculated, ANO will automatically start updating the eCPM on your behalf. If the AdMob Dashboard is showing a PENDING or ERROR status for more than 72 hours, verify that you have added the System User to each of your Properties.

Using rewarded ads

In the settings for your rewarded ad unit, provide values for the reward amount and reward type. Then, to ensure you provide the same reward to the user no matter which ad network is served, check the Apply to all networks in Mediation groups box.

If you don't apply this setting, the Facebook adapter defaults to a reward of type "" (empty string) with a value of 1. The Facebook SDK does not provide specific reward values for its rewarded ads.

For more information on setting reward values for AdMob ad units, see Create an ad unit.

Step 3: Import the Facebook Audience Network SDK and adapter

Using CocoaPods (recommended)

• Add the following line to your project's Podfile:

  pod 'GoogleMobileAdsMediationFacebook'
  

• From the command line run:

  pod install --repo-update

Manual integration

• Download the latest version of the Facebook Audience Network SDK for iOS and link FBAudienceNetwork.framework in your project.
• Download the latest version of the Facebook adapter from the download link in the Changelog and link FacebookAdapter.framework in your project.

Step 4: Additional code required

Advertising tracking enabled

If you are building for iOS 14 or later, Facebook requires that you explicitly set their Advertising Tracking Enabled flag using the following code:

Key Point: You need to set this flag prior to initializing the Mobile Ads SDK.

Swift

// Set the flag as true
FBAdSettings.setAdvertiserTrackingEnabled(true)

Objective-C

// Set the flag as true.
[FBAdSettings setAdvertiserTrackingEnabled:YES];

SKAdNetwork integration

Facebook asks that you add the following SKAdNetwork identifiers to your project's Info.plist file:

<array>
    <dict>
        <key>SKAdNetworkIdentifier</key>
        <string>v9wttpbfk9.skadnetwork</string>
    </dict>
    <dict>
        <key>SKAdNetworkIdentifier</key>
        <string>n38lu8286q.skadnetwork</string>
    </dict>
</array>

Step 5: Test your implementation

See the Testing Audience Network Implementation guide guide for detailed instructions on how to enable Facebook test ads. You can then use the Mediation Test Suite to verify if your implementation is correct.

That's it! You now have a working mediation integration with Facebook's Audience Network.

Optional steps

EU Consent and GDPR

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

Please review Facebook's guidance for information about GDPR and Facebook advertising.

CCPA

The California Consumer Privacy Act (CCPA) requires giving California state residents the right to opt out of the "sale" of their "personal information" (as the law defines those terms), with the opt-out offered via a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The CCPA preparation guide offers the ability to enable restricted data processing for Google ad serving, but Google is unable to apply this setting to each ad network in your mediation chain. Therefore, you must identify each ad network in your mediation chain that may participate in the sale of personal information and follow guidance from each of those networks to ensure compliance with CCPA.

Please review Facebook's documentation for data processing options for users in California.

Using native ads

Some Facebook native ad assets do not map one to one to Google native ad assets. Such assets are passed back to the publisher in the extraAssets property of GADNativeAd. Here's a code example showing how to extract these assets:

Swift

let socialContext: String = unifiedNativeAd.extraAssets[GADFBSocialContext]

Objective-C

NSString *socialContext = unifiedNativeAd.extraAssets[GADFBSocialContext];

Using Facebook Native Ads without a MediaView

Facebook's native ad format requires rendering the GADMediaView asset. If you plan to render native ads without that asset, make sure to use Facebook's native banner ad format.

To use Facebook's native banner ads instead, you must:

• Select the Native Banner format when setting up Facebook Audience Network.

• Use Facebook adapter 5.5.0.0 or higher.

• For waterfall mediation, pass an extra parameter into the ad request indicating you want to request a native banner ad, as shown below.

Swift

#import "FacebookAdapter.h"
//...

let request = GADRequest()
let extras = GADFBNetworkExtras()
extras.nativeAdFormat = GADFBAdFormatNativeBanner
request.register(extras)

Objective-C

#import <FacebookAdapter/FacebookAdapter.h>
//...

GADRequest *request = [GADRequest request];
GADFBNetworkExtras * extras = [[GADFBNetworkExtras alloc] init];
extras.nativeAdFormat = GADFBAdFormatNativeBanner;
[request registerAdNetworkExtras:extras];

Note: For Facebook Open Bidding integrations, the adapter automatically loads the ad format you defined when setting up Facebook Audience Network.

Ad rendering

The Facebook adapter returns its native ads as UnifiedNativeAd objects. It populates the following Native ads advanced field descriptions for a GADUnifiedNativeAd.

Field	Populated by Facebook adapter
Headline
Image	1
Body
App icon
Call to action
Advertiser Name
Star rating
Store
Price

¹ The Facebook adapter does not provide direct access to the main image asset for its native ads. Instead, the adapter populates the GADMediaView with a video or an image.

Impression and click tracking

The table below demonstrates when native ad impressions and clicks are recorded by the Google Mobile Ads SDK.

Integration type	Impression recording	Click recording
Open Bidding	1px of native ad on screen + asset rendering requirements	Facebook Audience Network SDK callback
Waterfall	Facebook Audience Network SDK callback	Facebook Audience Network SDK callback

For Open Bidding impressions, Facebook Audience Network has specific asset rendering requirements in order for an impression to be considered valid, depending on whether you selected the Native or Native Banner format when setting up Facebook Audience Network.

Facebook native format	Required asset	Required rendering class
Native	Media View	GADMediaView
Native Banner	App icon	UIImageView

Caution: Facebook Open Bidding impressions are not recorded if the above asset rendering requirements are not met.

Error codes

If the adapter fails to receive an ad from the Facebook Audience Network, publishers can check the underlying error from the ad response using GADResponseInfo.adNetworkInfoArray under the following classes:

GADMAdapterFacebook
GADMediationAdapterFacebook

Here are the codes and accompanying messages thrown by the Facebook Audience Network adapter when an ad fails to load:

Error code	Reason
101	Invalid server parameters (e.g. missing Placement ID).
102	The requested ad size does not match a Facebook Audience Network supported banner size.
103	The Facebook Audience Network ad object failed to initialize.
104	The Facebook Audience Network SDK failed to present their interstitial/rewarded ad.
105	Root view controller of the banner ad is nil.
106	The Facebook Audience Network SDK failed to initialize.
1000-9999	The Facebook Audience Network returned an SDK-specific error. See Facebook's documentation for more details.
