In addition to the Game ID and Placement ID, you will also need your Unity Ads API Key and Organization core ID for setting up your AdMob ad unit ID.
Navigate to the Monetization > Setup > API Management and take note of the Monetization Stats API Access Key.
Then, navigate to the Monetization > Organization Settings and take note of the Organization core ID.
Turn on test mode
Test mode can be enabled from the Unity Ads dashboard. Under your project's settings, select the Testing tab.
You can force test mode for your app by clicking the edit button beside Google Play Store , checking Override client test mode and selecting Force test mode ON (i.e. use test ads) for all devices.
Alternatively, you can enable test mode for specific devices by clicking the Add Test Device button.
Fill out the form and click Save.
Step 2: Set up Unity Ads demand in AdMob UI
Configure mediation settings for your ad unit
You need to add Unity Ads to the mediation configuration for your ad unit.
First, sign in to your AdMob account. Next, 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 Unity Ads 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, and then click Add Ad Units.

Add Unity Ads to GDPR and US state regulations ad partners list
Follow the steps in GDPR settings and US state regulations settings to add Unity Ads to the GDPR and US state regulations ad partners list in the AdMob UI.
Step 3: Import the Unity Ads SDK and adapter
Android Studio integration (recommended)
In your app-level build.gradle.kts
file, add the following implementation
dependencies and configurations. Use the latest versions of the Unity Ads SDK
and adapter:
dependencies {
implementation("com.google.android.gms:play-services-ads:23.3.0")
implementation("com.unity3d.ads:unity-ads:4.12.1")
implementation("com.google.ads.mediation:unity:4.12.2.0")
}
Manual integration
Download the latest Unity Ads SDK (
unity-ads.aar
) from their GitHub repository and add it to your project.Navigate to the Unity Ads adapter artifacts on Google's Maven Repository. Select the latest version, download the Unity Ads adapter's
.aar
file, and add it to your project.
Step 4: Implement privacy settings on Unity Ads SDK
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.
In SDK version 2.0.0, Unity Ads added an API to support privacy settings. The following sample code shows how to pass this consent information to the Unity Ads SDK. Should you choose to pass consent information to the Unity Ads SDK manually, it is recommended that this code is called prior to requesting ads through the Google Mobile Ads SDK.
Java
import com.unity3d.ads.metadata.MetaData;
// ...
MetaData gdprMetaData = new MetaData(this);
gdprMetaData.set("gdpr.consent", true);
gdprMetaData.commit();
Kotlin
import com.unity3d.ads.metadata.MetaData
// ...
val gdprMetaData = MetaData(this)
gdprMetaData["gdpr.consent"] = true
gdprMetaData.commit()
See Unity Ads' Privacy Consent and data APIs and Complying with GDPR guides for more details and the values that can be provided in each method.
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.
In SDK version 2.0.0, Unity Ads added an API to support privacy settings. The following sample code shows how to pass this consent information to the Unity Ads SDK. Should you choose to pass consent information to the Unity Ads SDK manually, it is recommended that this code is called prior to requesting ads through the Google Mobile Ads SDK.
Java
import com.unity3d.ads.metadata.MetaData;
// ...
MetaData ccpaMetaData = new MetaData(this);
ccpaMetaData.set("privacy.consent", true);
ccpaMetaData.commit();
Kotlin
import com.unity3d.ads.metadata.MetaData
// ...
val ccpaMetaData = MetaData(this)
ccpaMetaData["privacy.consent"] = true
ccpaMetaData.commit()
See Unity Ads' Privacy Consent and data APIs and Complying with CCPA guides for more details and the values that can be provided in each method.
Step 5: Add required code
No additional code is required for Unity Ads integrations.
Step 6: Test your implementation
Enable test ads
Make sure you register your test device for AdMob and enable test mode in Unity Ads UI.
Verify test ads
To verify that you are receiving test ads from Unity Ads, enable single ad source testing in ad inspector using the Unity Ads (Waterfall) ad source(s).
Error codes
If the adapter fails to receive an ad from Unity Ads,
publishers can check the underlying error from the ad response using
ResponseInfo.getAdapterResponses()
under the following classes:
com.google.ads.mediation.unity.UnityAdapter
com.google.ads.mediation.unity.UnityMediationAdapter
Here are the codes and accompanying messages thrown by the UnityAds adapter when an ad fails to load:
Error code | Reason |
---|---|
0-10 | UnityAds SDK returned an error. See code for more details. |
101 | UnityAds server parameters configured in the AdMob UI are missing/invalid. |
102 | UnityAds returned a placement with a NO_FILL state. |
103 | UnityAds returned a placement with a DISABLED state. |
104 | UnityAds tried to show an ad with a null context. |
105 | Context used to initialize, load and/or show ads from Unity Ads is not an Activity instance. |
106 | UnityAds tried to show an ad that's not ready to be shown. |
107 | UnityAds is not supported on the device. |
108 | UnityAds can only load 1 ad per placement at a time. |
109 | UnityAds finished with an ERROR state. |
200-204 | UnityAds Banner specific error. See code for more details. |
