Integrate PubMatic with bidding

  • This guide explains how to integrate PubMatic ads into your iOS app using the Google Mobile Ads SDK mediation for bidding integrations.

  • The PubMatic mediation adapter supports bidding and waterfall integrations for various ad formats including app open, banner, interstitial, rewarded, rewarded interstitial, and native ads.

  • Implementing PubMatic mediation requires setting up configurations in the PubMatic UI, setting up PubMatic demand in the Ad Manager UI, and importing the PubMatic SDK and adapter into your iOS project.

  • Proper implementation of privacy settings according to GDPR and US state regulations is necessary when using the PubMatic SDK.

  • Testing your implementation with test ads and verifying them through single ad source testing is recommended before releasing your app.

This guide shows you how to use Google Mobile Ads SDK to load and display ads from PubMatic using mediation, covering bidding integrations. It covers how to add PubMatic OpenWrap SDK to an ad unit's mediation configuration, and how to integrate the PubMatic OpenWrap SDK and adapter into an iOS app.

Before your app is finalized, you will be presented the appropriate entries to add to your app-ads.txt.

app-aps.txt

Step 3: Import the PubMatic OpenWrap SDK and adapter

  • Add the following line to your project's Podfile:

    pod 'GoogleMobileAdsMediationPubMatic'
    
  • From the command line run:

    pod install --repo-update

Manual integration

  1. Download the latest version of the PubMatic OpenWrap SDK for iOS 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 and link PubMaticAdapter.xcframework in your project.

Step 4: Implement privacy settings on PubMatic

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.

PubMatic automatically reads GDPR consent set by consent management platforms that support Google's Additional Consent specification, including the UMP SDK. For more information, see Pass GDPR and GDPR consent.

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.

PubMatic automatically reads GPP consent set by consent management platforms that support Google's Additional Consent specification, including the UMP SDK. For more information, see Pass GPP consent.

Step 5: Add required code

SKAdNetwork integration

Follow PubMatic'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 Ad Manager.

Verify test ads

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

Optional Steps

The PubMatic adapter returns its native ads as GADNativeAd objects. It populates the following fields for a GADNativeAd.
