Integrate AppLovin with mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from AppLovin using mediation, covering both bidding and waterfall integrations. It covers how to add AppLovin to an ad unit's mediation configuration, and how to integrate the AppLovin SDK and adapter into a Unity app.

Supported integrations and ad formats

The Ad Manager mediation adapter for AppLovin has the following capabilities:

Integration
Bidding
Waterfall
Formats
Banner  1
Interstitial
Rewarded

Banner ads (excluding MREC banners) are supported only in mediation. Bidding does not support any type of banner ads.

Requirements

  • Latest Google Mobile Ads SDK
  • Unity 5.6 or higher
  • [For bidding]: To integrate all supported ad formats in bidding, use Google Mobile Ads mediation plugin for AppLovin 4.2.0 or higher (latest version recommended)
  • To deploy on Android
    • Android API level 21 or higher
  • To deploy on iOS
    • iOS deployment target of 12.0 or higher
  • A working Unity project configured with Google Mobile Ads SDK. See Get Started for details.
  • Complete the mediation Get started guide

Step 1: Set up configurations in AppLovin UI

Sign up or log in to your AppLovin account.

To set up your AdMob ad unit, you'll need your AppLovin SDK Key and Report Key. To find them, go to the AppLovin UI > Account > Keys to see both values.

If you plan on just integrating bidding, you can proceed to configure your mediation settings.

Select app for mediation

Bidding

This step isn't required for bidding integrations.

Waterfall

On the AppLovin UI, select Applications under the Monetization section to get to your registered apps. Select the app you'd like to use with mediation from the list of available apps.

Create a zone

Bidding

This step isn't required for bidding integrations.

Waterfall

On the AppLovin UI, select Zones under the Monetization section to get to your registered zone IDs. If you have already created the required zones for your app, skip ahead to Step 2. To create a new zone ID, click Create Zone.

Enter the name of Zone ID, select Android as the Platform, and choose the Ad Type.

Configure Pricing for the zone by selecting either Flat CPM or Optimized by AppLovin. CPMs can be configured on a per country basis for the Flat CPM option. Then, click Save.

Android

iOS

Once the zone is created, the zone ID can be found under the Zone ID column.

Android

iOS

Turn on test mode

Follow the instructions in AppLovin's MAX Test Mode guide on how to enable AppLovin test ads.

Step 2: Set up AppLovin demand in Ad Manager UI

Configure mediation settings for your ad unit

Android

For instructions, see step 2 in the guide for Android.

iOS

For instructions, see step 2 in the guide for iOS.

Add AppLovin Corp. to GDPR and US state regulations ad partners list

Follow the steps in GDPR settings and US state regulations settings to add Applovin Corp. to the GDPR and US state regulations ad partners list in the AdMob UI.

Step 3: Import the AppLovin SDK and adapter

OpenUPM-CLI

If you have OpenUPM-CLI installed, you can install the Google Mobile Ads AppLovin Mediation Plugin for Unity to your project by running the following command from your project's root directory:

openupm add com.google.ads.mobile.mediation.applovin

OpenUPM

In your Unity project editor, select Edit > Project Settings > Package Manager to open the Unity Package Manager Settings.

Under the Scoped Registries tab, add OpenUPM as a scoped registry with the following details:

  • Name: OpenUPM
  • URL: https://package.openupm.com
  • Scope(s): com.google

OpenUPM Details

Then, navigate to Window > Package Manager to open the Unity Package Manager and select My Registries from the drop-down menu.

Unity Registries

Select the Google Mobile Ads AppLovin Mediation package and click Install.

Install from OpenUPM

Unity Package

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

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

Import from Unity

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

Force Resolve

Step 4: Implement privacy settings on AppLovin SDK

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.

Since Google Mobile Ads mediation plugin version 7.0.0, AppLovin supports reading the consent string from shared preferences and setting the consent status accordingly.

If you are not using Google Mobile Ads mediation plugin for Applovin version 7.0.0+ or not using a CMP that writes the consent string into the shared preferences, you can use AppLovin.SetHasUserConsent() and AppLovin.SetIsAgeRestrictedUser() methods. The following sample code shows how to pass consent information to the AppLovin SDK. These options must be set before you initialize the Google Mobile Ads SDK to ensure they get forwarded properly to the AppLovin SDK.

using GoogleMobileAds.Api.Mediation.AppLovin;
// ...

AppLovin.SetHasUserConsent(true);

Additionally, if the user is known to be in an age-restricted category, you can also set the below flag to true.

AppLovin.SetIsAgeRestrictedUser(true);

See AppLovin's privacy settings for more information.

US states privacy laws

U.S. states privacy laws require giving users 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 U.S. states privacy laws compliance 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.

The Google Mobile Ads mediation plugin for AppLovin version 6.3.1 includes the AppLovin.SetDoNotSell() method. The following sample code shows how to pass consent information to the AppLovin SDK. These options must be set before you initialize the Google Mobile Ads SDK to ensure they get forwarded properly to the AppLovin SDK.

using GoogleMobileAds.Api.Mediation.AppLovin;
// ...

AppLovin.SetDoNotSell(true);

See AppLovin's Privacy documentation for more information.

Step 5: Add required code

Android

No additional code is required for AppLovin integration.

iOS

SKAdNetwork integration

Follow AppLovin's documentation to add the SKAdNetwork identifiers to your project's Info.plist` file.

Step 6: Test your implementation

Enable test ads

Make sure you register your test device for AdMob and enable test mode in Applovin UI.

Verify test ads

To verify that you are receiving test ads from Applovin, enable single ad source testing in ad inspector using the Applovin (Bidding) and Applovin (Waterfall) ad source(s).

Optional steps

Optimizations

Adding a call to AppLovin.Initialize() to your launch activity provides AppLovin the ability to track events as soon as the app starts.

Error codes

If the adapter fails to receive an ad from AppLovin, publishers can check the underlying error from the ad response using ResponseInfo under the following classes:

Android

com.google.ads.mediation.applovin.mediation.ApplovinAdapter
com.google.ads.mediation.applovin.AppLovinMediationAdapter

iOS

GADMAdapterAppLovin
GADMAdapterAppLovinRewardBasedVideoAd
GADMediationAdapterAppLovin
