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.

Before you start Make sure you have correctly integrated ironSource SDK interstitial, rewarded video or banner mediation in your application.

Google Ad Manager ads are served using the AdMob SDK.

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.

AdMob does not allow setting up more than 3 ad zones of the same Ad Type in the same setup.
e.g. no more than three Rewarded Video ads are allowed for the mediation group.

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 Namewe 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

Automatic refresh: Select the “Do not refresh” option. (Reminder – you can control the refresh rate on the mediation platform)

  • 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:

App ID
The unique ID assigned to your app on Admob’s dashboard.
Ad Unit ID
The unique ID assigned to your app’s ad unit on Admob’s dashboard.
Client ID
This is the unique identifier that specifies the relationship between your account and the ad unit.
Client Secret
The secret key that pairs with the Client ID
Refresh Token
This is the refresh token the client application already received.

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:1admob

      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
          Admob 18
        3. Next, in Step 1: Select & Authorize APIS, enter ‘’ 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:
          Admob 22
