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 ads to an ad unit's mediation configuration and how to integrate the Facebook Audience Network SDK and adapter into an Unity app.

Supported formats and features

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

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

Requirements

• Unity 5.6 or higher
• Latest Google Mobile Ads SDK
• [For Open Bidding]: Google Mobile Ads mediation plugin for Facebook 2.11.0 or higher
• To deploy on Android
  • Android API level 16 or higher
• To deploy on iOS
  • iOS deployment target of 9.0 or higher
  • The latest Facebook Audience Network SDK usually requires the latest version of Xcode.
• A working Unity project configured with Google Mobile Ads SDK. See Get Started for details.

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 the platform you want to monetize.

Note: If your app supports both Android and iOS, you need to add each of them separately.

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

Android

iOS

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.

Key Point: If you plan to integrate the rewarded interstitial ad format, the corresponding Facebook format is Rewarded Video.

Waterfall

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

Key Point: If you plan to integrate the rewarded interstitial ad format, the corresponding Facebook format is Rewarded Video.

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.

Note: If you're deploying your Unity app to both Android and iOS, you need two AdMob ad units, one for each platform.

Android

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.

iOS

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.

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

Download the latest version of Google Mobile Ads mediation plugin for Facebook from the download link in the Changelog and extract the GoogleMobileAdsFacebookMediation.unitypackage from the zip file.

In your Unity project editor, select Assets > Import Package > Custom Package and find the GoogleMobileAdsFacebookMediation.unitypackage file you downloaded. Make sure that all the files are selected and click Import.

Then, select Assets > Play Services Resolver > Android Resolver > Force Resolve. The Unity Play Services Resolver library will perfrom dependency resolution from scratch and copy the declared dependencies into the Assets/Plugins/Android directory of your Unity app.

Step 4: Additional code required

Android

No additional code required for Facebook integration.

iOS

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>

Advertising tracking enabled

If you are building for iOS 14 or later, please check Facebook's instructions on how to set their Advertising Tracking Flag.

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.
