Download and Integrate

To download the Chartboost adapter, navigate to the Mediation Integration Tool. You must also download the Chartboost SDK:

  • Download the Chartboost SDK for iOS

  • Download the Chartboost SDK for Android

    • AndroidManifest: Chartboost adapters are released as an Android Archive (AAR) file starting with version The AAR includes the required Manifest data for Chartboost. As a result, you no longer need to update your AndroidManifest manually for any generic data, such as permissions and Activities. Any other app-level placement configuration required by Chartboost must be manually entered into the AndroidManifest.

    • Android build requirements: On Android, Chartboost SDK depends on two Google Play Services dependencies. Make sure the following dependencies are installed on your Android (and Unity to Android) projects:


Things to Know

  • eCPM value: eCPM data can be manually entered in the MoPub dashboard from Chartboost unless Auto CPM is enabled. On the Chartboost dashboard, eCPM for your campaign can be found under Analytics -> Campaign. It is recommended to check these values often and update in MoPub as necessary.

  • Waterfall ranking: To top-rank Chartboost in the mediation waterfall, follow these instructions.

  • Chartboost named locations: When setting up Chartboost for your MoPub Ad Units, leaving the “Location” field blank will default to the “Default” Chartboost named ad location value. In your waterfall setup, if you have multiple occurrences of Chartboost with more than three different locations associated, doing this is not recommended. If you need to use more than three locations, contact Chartboost directly. Read more about using custom named locations in Chartboost here.

  • CCPA: MoPub Chartboost adapters handle passing of GDPR consent but not CCPA. For details on how to include CCPA settings please see the instructions for CCPA on iOS and Android.

Set Up Your Chartboost Account

    For Rewarded Video, under App Settings, select Rewarded Video, and add the values for Rewarded Currency Name and Reward per View.

    By default the Chartboost SDK displays UI elements before and after the ad, detailing the rewards. If this is not your desired UX, consider disabling pre-roll and post-roll settings.

Test an Ad

We recommend that you test your Chartboost integration using MoPub mediation test mode to verify that the adapter works as expected. Test mode must be set up on both the MoPub side and the Chartboost side.

Set Up Test Mode on the MoPub Side

Refer to our Mediation Test Mode article for complete details on using this mode.

Set Up Test Mode on the Chartboost Side
