Android

App settings

iOS

App settings

AdMob requires the Chartboost User ID and User Signature for setting up your AdMob ad unit ID. You can find these parameters by clicking Chartboost mediation on the Chartboost UI.

Chartboost mediation dashboard

Navigate to the Resources > API Explorer tab and take note of your User ID and User Signature located under the Authentication section.

Chartboost api explorer

Turn on test mode

You can enable test mode on your app by navigating to the Apps management tab from the Chartboost UI, selecting your app from the list and clicking on Edit app settings.

Android

Edit app settings

iOS

Edit app settings

From your app's settings, you can toggle Test mode on your app.

Chartboost test mode

Once test mode is enabled, you can request ads using the ad unit ID created earlier and receive a Chartboost test ad.

After you are able to receive Chartboost test ads, your app will be placed on Chartboost's Publisher App Review. In order for monetization on Chartboost to work, the publisher app review will need to be approved by Chartboost.

Step 2: Set up Chartboost demand in AdMob UI

Configure mediation settings for your ad unit

Android

For instructions, see step 2 in the guide for Android.

iOS

For instructions, see step 2 in the guide for iOS.

Add Chartboost to GDPR and US state regulations ad partners list

Follow the steps in GDPR settings and US state regulations settings to add Chartboost to the GDPR and US state regulations ad partners list in the AdMob UI.

Step 3: Import the Chartboost SDK and adapter

Download the latest version of Google Mobile Ads mediation plugin for Chartboost from the download link in the Changelog and extract GoogleMobileAdsChartboostMediation.unitypackage from the zip file.

In your Unity project editor, select Assets > Import Package > Custom Package and find the GoogleMobileAdsChartboostMediation.unitypackage file you downloaded. Make sure that all the files are selected and click Import.

Then, select Assets > Play Services Resolver > Android Resolver > Force Resolve. The Unity Play Services Resolver library will perform dependency resolution from scratch and copy the declared dependencies into the Assets/Plugins/Android directory of your Unity app.

Step 4: Implement privacy settings on Chartboost SDK

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.

The Google Mobile Ads mediation plugin for Chartboost version 3.1.0 includes the Chartboost.AddDataUseConsent() method. The following sample code sets data use consent to NonBehavioral. If you choose to call this method, it is recommended that you do so prior to requesting ads using the Google Mobile Ads SDK.

using GoogleMobileAds.Api.Mediation.Chartboost;
// ...

Chartboost.AddDataUseConsent(CBGDPRDataUseConsent.NonBehavioral);

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.

The Google Mobile Ads mediation plugin for Chartboost version 3.1.0 includes the Chartboost.AddDataUseConsent() method. The following sample code sets data use consent to OptInSale. If you choose to call this method, it is recommended that you do so prior to requesting ads using the Google Mobile Ads SDK.

using GoogleMobileAds.Api.Mediation.Chartboost;
// ...

Chartboost.AddDataUseConsent(CBCCPADataUseConsent.OptInSale);

Step 5: Add required code

Android

No additional code is required for Chartboost integration.

iOS

SKAdNetwork integration

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

Step 6: Test your implementation

Enable test ads

Make sure you register your test device for AdMob and enable test mode in Chartboost UI.

Verify test ads

To verify that you are receiving test ads from Chartboost, enable single ad source testing in ad inspector using the Chartboost (Waterfall) ad source(s).

Optional Steps

Android

Permissions

For optimal performance, Chartboost recommends adding the following optional permissions to your app's AndroidManifest.xml file:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

iOS

No additional steps are required for iOS integration.
