Integrate Mintegral with mediation

  • This guide explains how to integrate Mintegral ads into a Flutter app using the Google Mobile Ads SDK through mediation for both waterfall and bidding.

  • The guide details the steps for setting up configurations in the Mintegral UI, including finding the App Key, adding an application, creating an ad placement, and locating API keys.

  • Requirements for integration include the latest Google Mobile Ads SDK, Flutter 3.7.0 or higher, and specific Android and iOS API levels/deployment targets.

  • The Mintegral SDK and adapter can be integrated via pub.dev or manual download.

  • Testing the implementation involves enabling test ads through AdMob and Mintegral test IDs and verifying ad sources using Ad Inspector.

    • Step 1: Set up configurations in Mintegral UI

    Sign up or Log in to your Mintegral account.

    Locate the App Key

    Navigate to the APP Setting tab and take note of the APP Key.

    Add a new application

    From the APP Setting tab, click the Add APP button.

    Select the Platform and fill out the rest of the form. Then, click Save.

    Android

    iOS

    Take note of your application's APP ID.

    Android

    Once your ad placement is created, take note of the Placement ID.

    Android

    iOS

    Android

    iOS

    Locate your Mintegral Reporting API Key

    Bidding

    This step isn't required for bidding integrations.

    Waterfall

    You will need your Mintegral Reporting API Key for setting up your AdMob ad unit ID. Navigate to Account > API Tools. Take note of your Skey and Secret.

    Update your app-ads.txt

    Authorized Sellers for Apps app-ads.txt 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.

    To implement app-ads.txt for Mintegral, see How app-Ads.txt Can Help Fight Ad Fraud.

    Step 2: Set up Mintegral 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 Mobvista/Mintegral to GDPR and US state regulations ad partners list

    Follow the steps in European regulations settings and US state regulations settings to add Mobvista/Mintegral to the European and US state regulations ad partners list in the AdMob UI.

    Step 3: Import the Mintegral SDK and adapter

    Integration through pub.dev

    (Android only) Add the following repositories to the build.gradle file inside your project's android directory:

      repositories {
      google()
      mavenCentral()
      maven {
          url = uri("https://dl-maven-android.mintegral.com/repository/mbridge_android_sdk_oversea")
      }
  }

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

    dependencies:
  gma_mediation_mintegral: ^2.1.5

    Manual Integration

    Download the latest version of Google Mobile Ads mediation plugin for Mintegral, 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_mintegral:
    path: path/to/local/package

    Step 4: Implement privacy settings on Mintegral SDK

    To comply with the Google EU User Consent Policy, 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 that consent is propagated to each ad source in your mediation chain.

    Mintegral Flutter adapter version 2.1.1 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to Mintegral SDK. For more information, see Mintegral's Android and iOS SDK Privacy Compliance Statement documentation.

    Step 5: Add required code

    Android

    No additional code is required for Mintegral integration.

    iOS

    SKAdNetwork integration

    Follow Mintegral'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.

    To get Mintegral test ads for banners, interstitials, rewarded and native ad formats, Mintegral recommends using the App Keys, App IDs, Placement IDs and Ad Unit IDs provided in the Mintegral Test ID page.

    Verify test ads

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

    Error codes

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

    Android

    com.mbridge.msdk
com.google.ads.mediation.mintegral.MintegralMediationAdapter

    iOS

    GADMediationAdapterMintegral

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

    Android
