See [Manage user access to your > account](https://support.google.com/admob/answer/2784628) for details. Follow the steps in [European regulations settings](https://support.google.com/admanager/answer/10113006#adding_ad_partners_to_published_gdpr_messages) and [US state regulations settings](https://support.google.com/admanager/answer/14117973) to add **PubMatic** to the European and US state regulations ad partners list in the Ad Manager UI. ## Step 3: Import the PubMatic OpenWrap SDK and adapter > [!NOTE] > **Note:** Failure to integrate the compatible PubMatic OpenWrap SDK and Google Mobile Ads SDK versions might lead to build issues. ### Recommended: Use Swift Package Manager Before you continue, you must have the minimum supported adapter version 4.10.0.0. To [add a package dependency](https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app#Add-a-package-dependency) to your project, follow these steps: 1. In Xcode, navigate to **File \> Add Package Dependencies...**. 2. In the prompt that appears, search the following package URL: https://github.com/googleads/googleads-mobile-ios-mediation-pubmatic.git 3. In **Dependency Rule** , select **Branch**. 4. In the text field, enter `main`. ### Manual integration 1. Download the latest version of the [PubMatic OpenWrap SDK for iOS](https://help.pubmatic.com/openwrap/reference/home-get-started-with-ios-openwrap-sdk-as-primary-ad-sdk#integrate-manually) and link all the `.xcframework` files and bundles in your project. 2. Download the latest version of the PubMatic adapter from the download link in the [Changelog](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/mediation/pubmatic.md.txt#pubmatic-ios-mediation-adapter-changelog) and link `PubMaticAdapter.xcframework` in your project. ### Use CocoaPods > [!CAUTION] > **Caution:** Starting December 2, 2026, the [CocoaPods Specs > repository](https://blog.cocoapods.org/CocoaPods-Specs-Repo/) is in read-only mode. As of this date, Google Mobile Ads SDK no longer publishes updated versions of mediation adapters for iOS to CocoaPods.
- Add the following line to your project's Podfile: pod 'GoogleMobileAdsMediationPubMatic' - From the command line run: ```bash pod install --repo-update ``` ## Step 4: Implement privacy settings on PubMatic To [comply with the Google EU User Consent Policy](https://www.google.com/about/company/consentstaging.html), 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. PubMatic OpenWrap SDK iOS adapter version 4.7.0.0 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to PubMatic OpenWrap SDK SDK. For more information, see [Pass GDPR and GDPR consent](https://help.pubmatic.com/openwrap/reference/advanced-topics#pass-gdpr-and-gdpr-consent). ### US states privacy laws [US states privacy laws](https://support.google.com/admanager/answer/9561023) 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](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/privacy/us-states) offers the ability to enable [restricted data processing](https://privacy.google.com/businesses/rdp/) 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. PubMatic automatically reads GPP consent set by consent management platforms that support [Google's Additional Consent specification](https://support.google.com/admanager/answer/9681920), including the [UMP SDK](https://developers.google.com/admob/ios/privacy.md.txt). For more information, see [Pass GPP consent](https://help.pubmatic.com/openwrap/reference/advanced-topics#pass-gpp-consent). ## Step 5: Add required code ### Implement SKAdNetwork Follow [PubMatic's documentation](https://help.pubmatic.com/openwrap/reference/home-get-started-with-ios-openwrap-sdk-as-primary-ad-sdk#configure-skadnetwork-settings-to-track-conversions) 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](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/test-ads.md.txt#enable_test_devices) for Ad Manager. > [!IMPORTANT] > **Important:** Disable test mode for Ad Manager and PubMatic OpenWrap SDK before releasing your app. ### Verify test ads To verify that you are receiving test ads from PubMatic OpenWrap SDK, enable [single ad source testing](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **PubMatic OpenWrap** ad source(s). ## Optional Steps ### Native ads #### Ad rendering The PubMatic adapter returns its native ads as `GADNativeAd` objects. It populates the following [fields](https://support.google.com/admanager/answer/6075370) for a [`GADNativeAd`](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/api/reference/Classes/GADNativeAd.md.txt). | Field | Assets always included by PubMatic adapter | |---|---| | Headline | Yes | | Image | Yes | | Body | Yes | | Icon | Yes | | Call to action | Yes | | Star rating | Yes | | Store | | | Price | Yes | | Advertiser | Yes | ## Error codes If the adapter fails to receive an ad from PubMatic, you can check the underlying error from the ad response using [`GADResponseInfo.adNetworkInfoArray`](https://developers.google.com/ad-manager/mobile-ads-sdk/ios/api/reference/Classes/GADResponseInfo.md.txt#adnetworkinfoarray) under the following classes: ```objective-c GADMediationAdapterPubMatic ``` Here are the codes and accompanying messages thrown by the PubMatic adapter when an ad fails to load: | Error code | Domain | Reason | |---|---|---| | 101 | com.google.ads.mediation.pubmatic | Server configuration missing a required publisher ID. | | 102 | com.google.ads.mediation.pubmatic | The bidding signal collection request failed because multiple formats, no format, or an unsupported format was specified in the request parameters. | | 103 | com.google.ads.mediation.pubmatic | Invalid ad configuration for loading an ad. | | 104 | com.google.ads.mediation.pubmatic | Failed to present an interstitial ad because the ad was not ready. | | 105 | com.google.ads.mediation.pubmatic | Failed to present an rewarded ad because the ad was not ready. | | 106 | com.google.ads.mediation.pubmatic | Failed to load one of the native ad image sources. | | 107 | com.google.ads.mediation.pubmatic | The ad configuration is missing a publisher ID. | | 108 | com.google.ads.mediation.pubmatic | The ad configuration is missing a profile ID. | | 109 | com.google.ads.mediation.pubmatic | The ad configuration contains a non-number profile ID. | | 110 | com.google.ads.mediation.pubmatic | The ad configuration is missing an ad unit ID. | | 111 | com.google.ads.mediation.pubmatic | PubMatic OpenWrap SDK failed to instantiate an ad size instance. | | 1001-5002 | Sent by PubMatic SDK | PubMatic SDK returned an error. See PubMatic's [documentation](https://pubmatic-sdk.s3.amazonaws.com/iosapidoc/html/Constants/POBErrorCode.html) for more details. | ## PubMatic iOS Mediation Adapter Changelog #### [Version 5.5.0.0](https://dl.google.com/googleadmobadssdk/mediation/ios/pubmatic/PubMaticAdapter-5.5.0.0.zip) - Verified compatibility with PubMatic OpenWrap SDK version 5.5.0.
