This guide is intended for publishers who want to use the MoPub SDK to load and display ads from Facebook Audience Network via mediation. Below, you will find information about the ad network, integration/setup instructions, and more. For more information about how MoPub mediation works, visit this guide.

Supported Ad Formats

The following ad formats are currently supported by Facebook Audience Network. For the latest support, visit the Facebook Audience Network homepage.

• Banner

  To request banner ads with a height greater than 250, you must configure your Facebook placement as a medium rectangle on the Facebook dashboard. Using a placement of type banner won’t return ads in this case.

• Medium Rectangle
• Interstitial
• Rewarded Video
• Native
• Native Banner

Download and Integration

To download the Facebook Audience Network adapters, navigate to the Mediation Integration Tool. You must also download the Facebook Audience Network SDK:

• Download the Facebook Audience Network SDK for iOS
• Download the Facebook Audience Network SDK for Android

For the latest download and integration instructions, consult Facebook Audience Network’s tutorials before you integrate the SDK and adapters.

Localhost Whitelisting

Facebook uses the device’s localhost (127.0.0.1) to cache ad media files. Because Android 9 blocks cleartext traffic by default, you must add the following XML configuration to your app’s Manifest to whitelist unsecure traffic (more details here):

    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">127.0.0.1</domain>
    </domain-config>

Request Native Banner Ads

MoPub now supports Facebook Audience Network native banner mediation as of v5.6.0.0 of the Android and iOS adapters. To get started, create a native banner placement on the Facebook Audience Network dashboard.

Facebook placement IDs can be enabled for native or native banner demand. You will pass a flag to MoPub to indicate your preference for native or native banner demand. Follow the appropriate instructions below based on the platform and your native ad integration.

Android Manual Native Ad Integration

1. In your native ad implementation, create a Map<String, Object> object containing your native banner preference. Set the flag’s value to true to request native banner, or false (or don’t set it at all) to request regular native ad.

    Map<String, Object> localExtras = new HashMap<>();
    localExtras.put("native_banner", true);
   

2. Pass the above Map to your MoPubNative instance before making the ad request. Subsequently, to change your preference, re-do step 1.

    MoPubNative.setLocalExtras(localExtras);
    // Make your ad request
   

3. (Optional) If you will be alternating between regular native as well as native banner requests, we recommend preparing separate XML layout files—one for each format. Then, when registering your native ad renderer, because at this time you are in control of which format is requested, you can pass in the corresponding layout to your renderer. Doing so allows you to avoid having assets unexpectedly laid out.

iOS Manual Native Ad Integration

1. In your native ad implementation, create an NSDictionary holding an {NSString : Boolean} pair containing your native banner preference. Set the flag’s value to true to request native banner, or false (or don’t set it at all) to request regular native ad.

    NSDictionary *localExtras = @{@"native_banner" : true}; 
   

2. Pass the above NSDictionary to your MPNativeAdRequestTargeting instance before making the ad request. Subsequently, to change your preference, re-do step 1.

    MPNativeAdRequestTargeting *targeting = [[MPNativeAdRequestTargeting alloc] init];
    targeting.localExtras = localExtras;
    // Make your ad request
   

3. (Optional) If you will be alternating between regular native as well as native banner requests, we recommend preparing separate layout files—one for each format. Then, when registering your native ad renderer, because at this time you are in control of which format is requested, you can pass in the corresponding layout to your renderer. Doing so allows you to avoid having assets unexpectedly laid out.

Android Ad Placer Integration

1. In your app, before you initialize MoPub, create a Map<String, String> object containing your native banner preference. Set the flag’s value to "true" (with the quotation marks because this API expects a String) to request native banner, or "false" (or don’t set it at all) to request regular native ad.

    Map<String, String> facebookNativeBanner = new HashMap<>();
    facebookNativeBanner.put("native_banner", "true");
   

2. In your SdkConfiguration.Builder, pass the above Map to the withMediatedNetworkConfiguration() call before initializing the MoPub SDK:

    SdkConfiguration.Builder configBuilder = new SdkConfiguration.Builder("YOUR_AD_UNIT_ID");
   
    configBuilder.withMediatedNetworkConfiguration(FacebookAdapterConfiguration.class.getName(), facebookNativeBanner);
    // Initialize MoPub
   

iOS Ad Placer Integration

1. In your app, before you initialize MoPub, create an NSDictionary holding an {NSString : Boolean} pair containing your native banner preference. Set the flag’s value to true to request native banner, or false (or don’t set it at all) to request regular native ad.

   NSDictionary * facebookConfig = @{ @"native_banner" : true};
   

2. In your MPMoPubConfiguration object, pass that NSDictionary to the mediatedNetworkConfigurations call before initializing the MoPub SDK:

    MPMoPubConfiguration * sdkConfig = [[MPMoPubConfiguration alloc] initWithAdUnitIdForAppInitialization: @"YOUR_AD_UNIT_ID"];
   
    NSMutableDictionary * config = [@{@"FacebookAdapterConfiguration" : facebookConfig} mutableCopy];
   
    sdkConfig.mediatedNetworkConfigurations = config;
    // Initialize MoPub
   

That’s it! When you make your ad request, we’ll inform Facebook that this is a native banner ad request.

Native Ad Advertiser Name Asset

Depending on the Facebook SDK version you are integrating, you will need to show only either the ad title or the advertiser name. For more information about Facebook’s implementation requirements, check out this article.

To show the advertiser name asset on Android, follow this guide. If you are on iOS, adapters will automatically manage showing the correct asset depending on the Facebook Audience Network SDK version you are integrating.

Android Integration Help

Facebook Audience Network adapters are released as an Android Archive (AAR) file starting from version 5.2.0.1. The AAR includes the required Manifest data for FAN. As a result, publishers no longer have to update their AndroidManifest manually for any generic data, such as permissions and Activities. Any other app-level placement configuration required by Facebook Audience Network must be manually entered into the AndroidManifest.

Set Up Facebook Audience Network on the MoPub Dashboard

Placement ID is required.

Migrate Facebook Audience Network from Custom Native Setup

1. Transfer Placement ID (if applicable) from the old custom native connection to the supported Facebook Audience Network instance.

2. MoPub will initiate the following Facebook Audience Network custom event class names to render the ads:

   • iOS

     • FacebookBannerCustomEvent
     • FacebookInterstitialCustomEvent
     • FacebookRewardedVideoCustomEvent
     • FacebookNativeCustomEvent

   • Android

     • com.mopub.mobileads.FacebookBanner
     • com.mopub.mobileads.FacebookInterstitial
     • com.mopub.mobileads.FacebookRewardedVideo
     • com.mopub.nativeads.FacebookNative

   If you are manually entering these class names, migrate to the new network setup and pause the “Custom Native Network.” If you are using your own custom event class names, have both the old custom native network and the new Facebook Audience Network network UI set up for backward compatibility.

Important: During migration, make sure the custom native network and the Facebook Audience Network network are not both live at the same time because this may impact your revenue.

Network Reporting and Auto CPM

To enable Facebook network reporting and Auto CPM, you must enter the System user token and Facebook business ID.

You can find the Facebook business ID from the URL of the Facebook Business Banager or Monetization Manager portal.

For the System user token, consult this Facebook help article, with instructions on how to generate a reporting token to use in the MoPub UI.

This setup is required to take advantage of Auto CPM.

Troubleshooting Tips

Invalid Credentials

1. Have you associated the system user for which you generated the token to the right property?
2. Did you assign the correct apps to the correct property? Here is the Facebook help article on how to create apps within properties: https://www.facebook.com/help/publisher/709041312624617?helpref=page_content
3. Still stuck? Reach out to your Facebook team for help and provide them with the app and property ids.

Apps Not Updating for Facebook

Confirm that all the apps that are connected to your Facebook token ID are correctly permissioned in Facebook Business Manager so that MoPub can collect the data for the placement IDs. Follow the instructions here: https://developers.facebook.com/docs/audience-network/reporting-api/systemuser

Test Ad

While testing your SDK integrations and network setups, it is recommended that you leverage test ad placements for a consistent fill rate. To set up test mode, please reference Facebook’s test ad article for instructions.

For details about available error codes as well as potential resolutions, reference Facebook’s documentation.
