Step 1: Set up configurations in Unity Ads UI

Create a project

On Unity Ads Dashboard, navigate to Projects and click Create Project.

Fill out the form and click Create Project to add your project.

Navigate to Monetization > Get started, then click Get started.

In the Project Setup modal, select I plan to use Mediation and Google Admob for Mediation Partner, then click Next.

Select your ad settings, then click Next.

Fill out the form, then click Add Project.

Take note of the Game ID.

Create an Ad Unit

Navigate to Monetization > Ad Units, then click Add Ad Unit.

Enter an Ad Unit Name, then select your Platform and Ad Format.

Finally, click Create to save your ad unit.

Add a Placement

Bidding

Contact your Google account manager to create bidding placements.

Waterfall

Once the project is created, navigate to Monetization > Placements. To create a new placement, click Add Placement for your ad unit.

Fill out the necessary details and click Add Placement.

Take note of the Placement ID.

Locate Unity Ads Reporting API key

Bidding

This step isn't required for bidding integrations.

Waterfall

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 Apple App 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.

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

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

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 (SDK).

Click How to sign a partnership agreement and set up a bidding partnership with Unity Ads.

Click Acknowledge & agree, then click Continue.

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

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

Waterfall

Under the Waterfall card in the Ad Sources section, select Add Ad Source. Then select Unity Ads.

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.

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

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

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

Using CocoaPods (recommended)

Add the following line to your project's Podfile:
```
pod 'GoogleMobileAdsMediationUnity'
```
From the command line run:
```
pod install --repo-update
```

Manual integration

Download the latest version of the Unity Ads SDK, and link UnityAds.framework in your project.
Download the latest version of the Unity Ads adapter from the download link in the Changelog and link UnityAdapter.framework in 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.

Swift

import UnityAds
// ...

let gdprMetaData = UADSMetaData()
gdprMetaData.set("gdpr.consent", value: true)
gdprMetaData.commit()

Objective-C

#import <UnityAds/UnityAds.h>
// ...

UADSMetaData *gdprMetaData = [[UADSMetaData alloc] init];
[gdprMetaData set:@"gdpr.consent" value:@YES];
[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.

Swift

import UnityAds
// ...

let ccpaMetaData = UADSMetaData()
ccpaMetaData.set("privacy.consent", value: true)
ccpaMetaData.commit()

Objective-C

#import <UnityAds/UnityAds.h>
// ...

UADSMetaData *ccpaMetaData = [[UADSMetaData alloc] init];
[ccpaMetaData set:@"privacy.consent" value:@YES];
[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

SKAdNetwork integration

Follow Unity Ads's documentation to add the SKAdNetwork identifiers to your project's Info.plist file.

Compile errors

Swift

No additional code is required for Swift integrations.

Objective-C

For Unity Ads adapter 4.4.0.0 or higher, you must follow the integration steps in the Unity documentation.

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 (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 GADResponseInfo.adNetworkInfoArray under the following classes:

GADMAdapterUnity
GADMediationAdapterUnity

Here are the codes and accompanying messages thrown by the UnityAds adapter when an ad fails to load:

Error code	Reason
0-9	UnityAds SDK returned an error. See Unity's documentation for more details.
101	UnityAds server parameters configured in the AdMob UI are missing/invalid.
102	Device not supported by UnityAds.
103	UnityAds finished presenting with error state kUnityAdsFinishStateError.
104	The Unity ad object is nil after calling its initializer.
105	Failed to show Unity Ads due to ad not ready.
106	UnityAds called a placement changed callback with placement state kUnityAdsPlacementStateNoFill.
107	UnityAds called a placement changed callback with placement state kUnityAdsPlacementStateDisabled.
108	An ad was already loaded for this placement. UnityAds SDK does not support loading multiple ads for the same placement.
