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.
You will be shown a list of all the placements you have. To create a new placement, click the Add Placement button on the dialog.
Fill out the form and click Save.
Finally, take note of the Placement ID.
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,
create an app-ads.txt file for Ad Manager.
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 Ad Manager UI

Add BidMachine to GDPR and US state regulations ad partners list
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 Ad Manager UI.
Step 3: Import the BidMachine SDK and adapter
Android Studio integration (recommended)
In your app-level gradle file, add the following implementation dependencies:
Kotlin
dependencies { implementation("com.google.android.gms:play-services-ads:25.3.0") implementation("com.google.ads.mediation:bidmachine:3.7.0.0") }
Groovy
dependencies { implementation 'com.google.android.gms:play-services-ads:25.3.0' implementation 'com.google.ads.mediation:bidmachine:3.7.0.0' }
Step 4: Implement privacy settings on BidMachine SDK
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 GDPR.
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 GPP.
Step 5: Add required code
No additional code needed for BidMachine integration.
Step 6: Test your implementation
Enable test ads
Make sure you register your test device for Ad Manager.
Follow the instructions in BidMachine's documentation for Android in order to enable test mode for BidMachine.
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).
Optional Steps
Native ads
Ad rendering
The BidMachine adapter returns its native ads as
NativeAd
objects. It populates the following
fields
for a
NativeAd.
| Field | Assets always included by BidMachine adapter |
|---|---|
| Headline | |
| Image | |
| Body | |
| Icon | |
| Call to action | |
| Star rating | |
| Store | |
| Price | |
| Advertiser |
Error codes
If the adapter fails to receive an ad from BidMachine, you can check the
underlying error from the ad response using
ResponseInfo.getAdapterResponses()
under the following classes:
io.bidmachine
com.google.ads.mediation.bidmachine
Here are the codes and accompanying messages thrown by the BidMachine adapter when an ad fails to load:
| Error code | Domain | Reason |
|---|---|---|
| 100 | com.google.ads.mediation.bidmachine | Invalid or empty placement ID received. |
| 101 | com.google.ads.mediation.bidmachine | Error during signal collection: No Signal Data Configuration found. |
