Step 1: Set up configurations in BidMachine UI

Log in to your BidMachine account dashboard.

Create new placements

Navigate to the Source tab and under the Sources table, select the Edit button.

Note: BidMachine automatically creates a Source for you. If you want to create a new Source, please reach out to your account maanger.

Android

iOS

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 BidMachine, navigate to the app-ads.txt tab from the Dashboard. Then, copy the list and append it to your website's app-ads.txt file.

Step 2: Set up BidMachine 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 BidMachine to GDPR and US state regulations ad partners list

Important: Verify that you have Account Management permission to complete the configuration for EU Consent and GDPR, US State regulations, and User Messaging Platform. See Manage user access to your account for details.

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

Step 3: Import the BidMachine SDK and adapter

Note: Failure to integrate the compatible BidMachine and Google Mobile Ads Unity Plugin versions might lead to build issues.

OpenUPM-CLI

Important: If you are migrating from using a .unitypackage to using OpenUPM-CLI, you must manually uninstall the assets from the old location by deleting all files from the Assets/GoogleMobileAds/Mediation/BidMachine folder.

If you have OpenUPM-CLI installed, you can install the Google Mobile Ads BidMachine 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.bidmachine

OpenUPM

Important: If you are migrating from using a .unitypackage to using OpenUPM, you must manually uninstall the assets from the old location by deleting all files from the Assets/GoogleMobileAds/Mediation/BidMachine folder.

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

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

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

Unity Package

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

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

Then, select Assets > External Dependency Manager > Android Resolver > Force Resolve. The External Dependency Manager 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 BidMachine SDK

EU Consent and GDPR

To comply with 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 consent is propagated to each ad source in your mediation chain. Google is unable to pass the user's consent choice to such networks automatically.

BidMachine automatically reads GDPR consent set by consent management platforms including the UMP SDK. For more information, see BidMachine's GDPR guide for Android and iOS.

US states privacy laws

US 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 through a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The US 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.

BidMachine automatically reads GPP consent set by consent management platforms including the UMP SDK. For more information, see BidMachine's GPP guide for Android and iOS.

Step 5: Add required code

Android

No additional code required for BidMachine integration.

iOS

SKAdNetwork integration

Follow BidMachine's documentation on SKAdNetwork Support 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.

Follow the instructions in BidMachine's documentation for Android and iOS in order to enable test mode for BidMachine.

Important: Disable test mode for AdMob and BidMachine before releasing your app.

Verify test ads

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