Google AdMob Integration Guide

This guide instructs you step-by-step on how to set AdMob and AdMob Native as live ad networks on Unity LevelPlay Mediation.

Step 1. Create an AdMob Account

1. To access AdMob’s banner and native ad inventory through Unity LevelPlay Mediation, you need to create an account with AdMob.
2. It’s recommended to adjust the time zone of your AdMob account to UTC to align with the ironSource platform. This will ensure accurate reporting. Learn more.

Step 2. Create an Application and Ad Zone in Admob

Next, you must add your app and set up Ad Zones in your AdMob account.

Add Your App

• Log into your AdMob account. On your dashboard, click Apps. 
  
• A modal will appear where you can either search for your app, add your app manually or simply select an existing app to monetize.
  
  
  Note: You’ll need a unique AdMob application per platform (iOS + Android), just like your ironSource account.
• Select interstitial, rewarded video, banners, or native advanced (native ads for banners) as your ad unit format and enter the relevant details.
  
• Interstitial
  • Ad Type: You can leave the two boxes checked as we support text, image, video, and rich media in interstitials.
  • Ad unit name: we recommend naming the ad unit intuitively so it will be easy to recognize as the ad unit you’ll be serving AdMob Interstitials through Unity LevelPlay Mediation.
    
• Rewarded Video
  • Ad unit name: we recommend naming the ad unit intuitively so it will be easy to recognize as the ad unit you’ll be serving AdMob’s Rewarded Video through Unity LevelPlay Mediation.
    
•  Banners
  • Ad Unit Name: we recommend naming the ad unit intuitively so it will be easy to recognize as the ad unit you’ll be serving AdMob Banners  Unity LevelPlay Mediation
  • eCPM floor – Enable and enter an eCPM value according to your country and waterfall strategy

• Native Banners

Native ads for banners enables you to access native ad demand from Google AdMob. This means that you can increase banner performance by accessing both Google’s native and banner demand.

• • Ad unit name: Type a name that you are going to easily recognize
  • Advanced settings: Select both Image and Video
  • eCPM floor – Enable and enter an eCPM value according to your country and waterfall strategy

Now retrieve your App ID and Ad Unit ID and save them for later use. Then, click Done.

Step 3. Activate AdMob in Your ironSource Network Setup Module

Sign in to your Google account when setting up AdMob on the ironSource SDK Networks Setup page and the necessary parameters to run AdMob interstitials, rewarded video, banners, and native ads will automatically be retrieved. 

There are a few pieces of data from your AdMob account which need to be inserted into your ironSource Network Setup Module in order for AdMob to work correctly with the ironSource SDK:

Once you obtain this information, you must configure AdMob’s Parameters in your ironSource Account. By adding the above information correctly, you will be able to take full advantage of AdMob’s ad inventory and reporting data on Unity LevelPlay Mediation.

• • 1. App ID
       To retrieve your App ID, go to ‘Apps’ tab on the left side bar on Admob’s platform and click on ‘App Settings’ .  You will then see the application’s settings, as well as the App ID.
       
    2. Ad Unit ID
       To retrieve your Ad Unit ID, go to ‘Apps’ tab on the left side bar on Admob’s platform and click on ‘Ad Units’. You will then see the application’s ad units, as well as the Ad Unit ID.
       
    3. Client ID  and Client Secret
       1. To retrieve your Client ID & Client Secret, go to Google’s API Manager.
       2. Click on the API Project drop-down at the upper-left of the page, select ‘Create a project’ or select the project you already created for this app:
          In the case you are creating a new project for this purpose,  provide a Project name, Billing account and Location in the dialog box that appears and click ‘Create’:
          
       3. In the left sidebar, select Credentials, then select the OAuth consent screen tab. On this page, provide a Product Name. Click Save:

       5. Next, enable the AdMob API:
          
       6. Select the Credentials tab in the left sidebar. Click the Create Credentials drop-down and select OAuth client ID
       7. Select Web application, and provide a name for your app. In the fields below, you must enter https://developers.google.com/oauthplayground for at least one Authorized redirect URI. For example:
          • Authorized JavaScript origins: https://YOUR_NAMESPACE (Optional)
          • Authorized redirect URI: https://developers.google.com/oauthplayground
       8. Click Create, and you will be presented with your Client ID and Client Secret:
          
    4. Refresh Token
       
       1. To retrieve your Refresh Token, go to the OAuth 2.0 Playground.
       2. Click the settings icon in the upper right corner. Uncheck the box labeled Force approval prompt and check Use your own OAuth credentials. Input your Client ID and Client Secret
          
       3. Next, in Step 1: Select & Authorize APIS, enter ‘https://www.googleapis.com/auth/admob.report’ and click Authorize APIs:
          
       4. Grant your project access to your AdMob data
       5. You should then receive the Authorization Code from Step 1 and will be able to click the Exchange authorization code for tokens button. Then you will get a Refresh token as well as an Access Token:
          

Configure AdMob Parameters in your ironSource Account

• • • Once you have all of these parameters, log in to your ironSource account and go to ‘Monetize‘ ➣ ‘SETUP‘ ➣ ‘SDK Networks‘.
      
    • Select Admob from the list of Manage Networks and enter the Admob Client ID, Client Secret and Refresh Token or click the Login with Google option.
      
      Login with Google:
    • Click Save. AdMob and AdMob Native will then be enabled in the Available Ad Networks table.
      
    • Next, select the app on which you’d like to run Unity LevelPlay’s Mediation with AdMob.
    • Select Admob from the Setup list of Ad Networks and click on the tool Define icon. Then insert the App ID and Ad Unit ID  under Interstitial, Rewarded Video or Banner Settings.
      
    • Verify your integration with the Reporting API; this column will check your integration through the Reporting API and return three possible responses: Verified, Failed and No Response. Double check your integration and the information you entered above; then click ‘Retry‘ until you see ‘Verified’.

Step 4. Add the Admob Adapter to Your Build

<key>GADApplicationIdentifier</key>
<string>[APP_ID]</string>

iOS

ironSource SDK supports both Cocoapods and Manual download mechanisms.

Cocoapods

To integrate the AdMob SDK with Cocoapods, enter the following line in your podfile and you’re good to go!

pod 'IronSourceAdMobAdapter','4.3.58.0'

Manual Download

1. Download the AdMob Adapter
   Add the AdMob Adapter and SDK to your build. You can find the latest AdMob Adapter and SDK here.
   As the AdMob Adapter does not contain the AdMob SDK. You need to add the AdMob SDK to your project as well.
2. Add the AdMob XCframeworks to your Project
   • After you download the Adapter and SDK, drop the Adapter and SDK XCframework files into your Xcode Project.
   • if you are importing the framework without the xcframework drop resource file for native banners 
3. Open Target ➣ Build Settings ➣ Architectures and confirm that your Xcode Project uses Base SDK version 8.0 or greater and that it does not use armv6 architecture.
4. Linker Flags:
   Add two separate linker flags to Target ➣ Build Settings ➣ Linking ➣ Other Linker Flags:
   –ObjC

Step 5. Update Info.plist

As of V7.42.0 (Adapter version 4.3.3 onwards), AdMob’s SDK requires publishers to add their AdMob App ID to the app’s plist as described here.
Alternatively, you can make this change programmatically

<key>GADApplicationIdentifier</key>
<string>[APP_ID]</string>

Replace the “GADApplicationIdentifier” value with the APP ID value you retrieve in step 3.
Not doing so results in crashes originated with AdMob’s SDK. For more information please refer to AdMob’s guide.

Step 6. Additional Steps
