    Step 3: Import the maio SDK and adapter

    If you have OpenUPM-CLI installed, you can install the Google Mobile Ads maio Mediation Plugin for Unity to your project by running the following command from your project's root directory:

    openupm add com.google.ads.mobile.mediation.maio

    OpenUPM

    In your Unity project editor, select Edit > Project Settings > Package Manager to open the Unity Package Manager Settings.

    Under the Scoped Registries tab, add OpenUPM as a scoped registry with the following details:

    • Name: OpenUPM
    • URL: https://package.openupm.com
    • Scope(s): com.google

    OpenUPM Details

    Then, navigate to Window > Package Manager to open the Unity Package Manager and select My Registries from the drop-down menu.

    Unity Registries

    Select the Google Mobile Ads Maio Mediation package and click Install.

    Install from OpenUPM

    Unity Package

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

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

    Step 5: Test your implementation

    Enable test ads

    Make sure you register your test device for Ad Manager.

    Publishers using version 7.26.0 or higher of Google Mobile Ads Unity Plugin will automatically receive test ads from maio on phones and tablets registered as test devices when making requests.

    Verify test ads

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

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

    Android

    Format Class name
