Integrate Chartboost with mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from Chartboost using mediation, covering waterfall integrations. It covers how to add Chartboost to an ad unit's mediation configuration, and how to integrate the Chartboost SDK and adapter into a Flutter app.

Supported integrations and ad formats

The AdMob mediation adapter for Chartboost has the following capabilities:

Requirements

• Latest Google Mobile Ads SDK
• Flutter 3.7.0 or higher
• To deploy on Android
  • Android API level 21 or higher
• To deploy on iOS
  • iOS deployment target of 12.0 or higher
• A working Flutter project configured with Google Mobile Ads SDK. See Get Started for details.
• Complete the mediation Get started guide

Step 1: Set up configurations in Chartboost UI

Sign up for a Chartboost account and log in once your account is verified. Then, navigate to the Apps management tab.

Click the Add new app button to create your app.

Fill out the rest of the form and click the Add App button to finalize your app.

After your app is created, you will be directed to its dashboard. Take note of the App ID and App Signature of your app.

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.

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

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.

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

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

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

Integration through pub.dev

Add the following dependency with the latest versions of the Chartboost SDK and adapter in your package's pubspec.yaml file:

dependencies:
  gma_mediation_chartboost: ^1.0.0

Manual Integration

Download the latest version of Google Mobile Ads mediation plugin for Chartboost, extract the downloaded file, and add the extracted plugin folder (and its contents) to your Flutter project. Then, reference the plugin in your pubspec.yaml file by adding the following dependency:

dependencies:
  gma_mediation_chartboost:
    path: path/to/local/package

Step 4: Implement privacy settings on Chartboost 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.

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

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).

Error codes

If the adapter fails to receive an ad from Chartboost, publishers can check the underlying error from the ad response using ResponseInfo under the following classes:

com.google.ads.mediation.chartboost.ChartboostAdapter
com.google.ads.mediation.chartboost.ChartboostMediationAdapter

GADMAdapterChartboost
GADMediationAdapterChartboost
