### Update your app-ads.txt


[Authorized Sellers for Apps app-ads.txt](https://iabtechlab.com/wp-content/uploads/2019/03/app-ads.txt-v1.0-final-.pdf) is an IAB Tech Lab initiative that helps ensure your
app ad inventory is only sold through channels you've identified as authorized. To prevent a
significant loss in ad revenue, you'll need to implement an `app-ads.txt` file.

If you haven't done so already,

[set up an app-ads.txt file for your app](https://support.google.com/admob/answer/9363762).

To implement `app-ads.txt` for Unity Ads, see
[setting up app-ads.txt for the first time](https://docs.unity.com/grow/en-us/ads/optimization/app-ads-txt#setting-up-app-adstxt-for-the-first-time).

### Turn on test mode

Test mode can be enabled from the
[Unity Ads dashboard](https://cloud.unity.com/home/). Navigate to

![](https://developers.google.com/static/admob/images/mediation/unity/test_devices.png)

## 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](https://apps.admob.com/). 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](https://developers.google.com/admob/android/mediation/unity#add-ad-source).

To create a new mediation group, select **Create Mediation Group**.

![](https://developers.google.com/static/admob/images/mediation/admob-mediation-group-create.png)

Enter your ad format and platform, then click **Continue**.

![](https://developers.google.com/static/admob/images/mediation/admob-mediation-group-new-Android.png)

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**.

Associate this mediation group with one or more of your existing
AdMob ad units. Then click **Done**.

![](https://developers.google.com/static/admob/images/mediation/admob-ad-units-select-Android.png)

You should now see the ad units card populated with the ad units you selected:

![](https://developers.google.com/static/admob/images/mediation/admob-ad-units-card-Android.png)

#### Add Unity Ads as an ad source

### Bidding

Under the **Bidding** card in the **Ad Sources** section, select **Add
ad source** . Then select **Unity Ads** .  

Click **How to sign a partnership agreement** and [set up a bidding partnership](https://support.google.com/admob/answer/9842838) with Unity Ads.   

![](https://developers.google.com/static/admob/images/mediation/unity/bidding-agreement-1.png)   

Click **Acknowledge \& agree** , then click **Continue** .   

![](https://developers.google.com/static/admob/images/mediation/unity/bidding-agreement-2.png)   

If you already have a mapping for Unity Ads, you can select it. Otherwise, click **Add mapping** .   

![](https://developers.google.com/static/admob/images/mediation/unity/bidding-add-mapping-1-Android.png)   

Next, enter the **Game ID** and **Placement ID** obtained in the previous section. Then click **Done** .   

| **Important** : The **Game ID** must be associated with the targeted app as in the Unity Ads UI.

<br />

![](https://developers.google.com/static/admob/images/mediation/unity/bidding-add-mapping-2-Android.png)

### Waterfall

<br />

Under the **Waterfall** card in the **Ad Sources** section, select **Add Ad
Source** .  

Select **Unity Ads** and enable the **Optimize** switch. Enter the **API Key** and **Organization core ID** obtained in the previous section to set up ad source optimization for Unity Ads. Then enter an **eCPM value** for Unity Ads and click **Continue** .  

![](https://developers.google.com/static/admob/images/mediation/unity/admob-add-ad-network.png)  
| **Note**: You only need to set up ad source optimization once per network.

If you already have a mapping for Unity Ads, you can select it. Otherwise, click **Add mapping** .  
![](https://developers.google.com/static/admob/images/mediation/unity/waterfall-add-mapping-1-Android.png)  
Next, enter the **Game ID** and **Placement ID** obtained in the previous section. Then click **Done** .  
| **Important** : The **Game ID** must be associated with the targeted app as in the Unity Ads UI.

![](https://developers.google.com/static/admob/images/mediation/unity/waterfall-add-mapping-2-Android.png)  
| **Note** : Ad source optimization takes a few days to gather enough data to accurately calculate eCPM for a mediation network. In the meantime, the ad source optimization status is `PENDING`, so you must manually set an eCPM value for the network. Once the eCPM can be calculated, the ad source automatically starts updating the eCPM on your behalf.

### Add Unity Ads to GDPR and US state regulations ad partners list

| **Important:** Verify that you have **Account Management** permission to complete the configuration for EU Consent and GDPR, US State regulations, and User Messaging Platform. See [Manage user access to your
| account](https://support.google.com/admob/answer/2784628) for details.

Follow the steps in

[European regulations settings](https://support.google.com/admob/answer/10113004#adding_ad_partners_to_published_gdpr_messages)

and

[US state regulations settings](https://support.google.com/admob/answer/14125907)

to add **Unity Ads** to the
European and US state regulations ad partners list in the AdMob UI.

## Step 3: Import the Unity Ads SDK and adapter

| **Note:** Failure to integrate the compatible Unity Ads and Google Mobile Ads SDK versions might lead to build issues.

### Android Studio integration (recommended)

In your app-level gradle file, add the following implementation
dependencies:  

### Kotlin

```kotlin
dependencies {
    implementation("com.google.android.gms:play-services-ads:24.9.0")
    implementation("com.unity3d.ads:unity-ads:4.16.5")
    implementation("com.google.ads.mediation:unity:4.16.5.0")
}
```

### Groovy

```groovy
dependencies {
    implementation 'com.google.android.gms:play-services-ads:24.9.0'
    implementation 'com.unity3d.ads:unity-ads:4.16.5'
    implementation 'com.google.ads.mediation:unity:4.16.5.0'
}
```

### Manual integration

1. Download the latest Unity Ads SDK (`unity-ads.aar`) from their
   [GitHub repository](https://github.com/Unity-Technologies/unity-ads-android/releases)
   and add it to your project.

2. Navigate to the
   [Unity Ads adapter artifacts](https://maven.google.com/web/index.html#com.google.ads.mediation:unity)
   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


To [comply with
Google EU User Consent Policy](https://www.google.com/about/company/consentstaging.html), you must make certain disclosures to your
users in the European Economic Area (EEA), the UK, and Switzerland, and obtain
their consent for the use of cookies or other local storage where legally
required, and for the collection, sharing, and use of personal data for ads
personalization. This policy reflects the requirements of the EU ePrivacy
Directive and the General Data Protection Regulation (GDPR). You are
responsible for verifying consent is propagated to each ad source in your
mediation chain.
Google 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

    MetaData gdprMetaData = new MetaData(this);
    gdprMetaData.set("gdpr.consent", true);
    gdprMetaData.commit();  
    https://github.com/googleads/googleads-mobile-android-mediation/blob/0e5f5b9bbfc6e3b4b2a58837eae5dc261e5aecd4/Example/snippets/src/main/java/com/google/ads/mediation/snippets/java/UnityAdsMediationSnippets.java#L30-L32

### Kotlin

    val gdprMetaData = MetaData(this)
    gdprMetaData["gdpr.consent"] = true
    gdprMetaData.commit()  
    https://github.com/googleads/googleads-mobile-android-mediation/blob/0e5f5b9bbfc6e3b4b2a58837eae5dc261e5aecd4/Example/snippets/src/main/java/com/google/ads/mediation/snippets/kotlin/UnityAdsMediationSnippets.kt#L30-L32

See Unity Ads'
[GDPR Compliance](https://docs.unity.com/en-us/grow/ads/privacy/gdpr-compliance)
for more details and the values that can be provided in each method.

### US states privacy laws


[US states privacy laws](https://support.google.com/admob/answer/9561022)
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 through a prominent "Do Not Sell My Personal
Information" link on the "selling" party's homepage. The
[US states privacy
laws compliance guide](https://developers.google.com/admob/android/privacy/us-states) offers the ability to enable
[restricted data processing](https://privacy.google.com/businesses/rdp/)
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 Google Mobile Ads SDK.  

### Java

    MetaData ccpaMetaData = new MetaData(this);
    ccpaMetaData.set("privacy.consent", true);
    ccpaMetaData.commit();  
    https://github.com/googleads/googleads-mobile-android-mediation/blob/0e5f5b9bbfc6e3b4b2a58837eae5dc261e5aecd4/Example/snippets/src/main/java/com/google/ads/mediation/snippets/java/UnityAdsMediationSnippets.java#L38-L40

### Kotlin

    val ccpaMetaData = MetaData(this)
    ccpaMetaData["privacy.consent"] = true
    ccpaMetaData.commit()  
    https://github.com/googleads/googleads-mobile-android-mediation/blob/0e5f5b9bbfc6e3b4b2a58837eae5dc261e5aecd4/Example/snippets/src/main/java/com/google/ads/mediation/snippets/kotlin/UnityAdsMediationSnippets.kt#L38-L40

See Unity Ads'
[Consumer privacy act compliance](https://docs.unity.com/en-us/grow/ads/privacy/ccpa-compliance)
for more details and the values that can be provided in each method.

## Step 5: Add required code

#### Load ad with Activity context

Pass `Activity` context when loading Banner, Interstitial and Native ad formats.
Without activity context, ad load will fail.

## Step 6: Test your implementation

### Enable test ads

Make sure you
[register your test device](https://developers.google.com/admob/android/test-ads#enable_test_devices)
for

AdMob and [enable test mode](https://developers.google.com/admob/android/mediation/unity#turn-on-test-mode) in
Unity Ads UI.


| **Important:** Disable test mode for AdMob and Unity Ads before releasing your app.

### Verify test ads

To verify that you are receiving test ads from
Unity Ads,
enable
[single ad source testing](https://developers.google.com/admob/android/ad-inspector#single_ad_source_testing)
in ad inspector using the
**Unity Ads (Bidding) and 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()`](https://developers.google.com/admob/android/reference/com/google/android/gms/ads/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](https://github.com/googleads/googleads-mobile-android-mediation/blob/master/ThirdPartyAdapters/unity/unity/src/main/java/com/google/ads/mediation/unity/UnityAdsAdapterUtils.java#L94-L127) 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](https://github.com/googleads/googleads-mobile-android-mediation/blob/b1a70fcab0e7891efacffdff523d86573e2286c7/ThirdPartyAdapters/unity/unity/src/main/java/com/google/ads/mediation/unity/UnityAdsAdapterUtils.java#L69-L84) for more details. |
