Google Ads API v24.2 adds approvals, AI content labels, and new analytics

Google Ads API v24.2 pushed account security, AI disclosure, and reporting into the same release. Google announced the minor update on Wednesday, June 24, 2026, and said advertisers and developers had to upgrade client libraries and code to use the new capabilities. It also rolled out v23.3, v22.2 and v21.2 at the same time to extend support for multi-party approvals and synthetic content labeling, with a live walkthrough set for June 25 at 10 a.m. ET on Discord and YouTube Live.

The clearest operational change is multi-party approval. Google’s help documentation says the feature protects accounts from unauthorized activity by requiring a second administrator to verify sensitive changes. Adding users, changing user roles and adjusting access levels now trigger that extra approval step. For agencies managing large client rosters, that is not a cosmetic control. It is a hard gate on the kinds of account changes that cause the most damage when someone makes a mistake, or when a compromised login starts moving fast.

Google also expanded AI content disclosure across the API with SyntheticContentInfo and SyntheticContentAttestation on both Asset and Ad resources. The company said developers can use those fields to label AI-generated creative, and that both advertiser and Google systems can attest whether an asset or ad was generated fully automatically or with advertiser review. The attestation interface is visible in v22 and later, but the fields stay immutable there until v25, which makes v24.2 an intermediate step toward more automated disclosure workflows.

That timing tracks directly to regulation. Google tied the disclosure work to the EU AI Act, which the European Commission says will bring transparency obligations into force on August 2, 2026. The Commission has also published a voluntary Code of Practice on marking and labelling AI-generated content, giving ad-tech teams a practical reference point as they build disclosure into campaign ops and creative approval chains.

On the measurement side, v24.2 gave Performance Max more useful reporting. Google said performance_max_placement_view can now be segmented by ad_network_type, which gives agencies a cleaner read on where inventory lands across Search, YouTube, Display, Discover, Gmail and Maps. The release also added COMPARE_CAMPAIGNS, which lets advertisers assign existing campaigns across up to five experiment arms and matches Custom mixed campaign types in the Google Ads UI. Google added a workflow for testing text customization and final URL expansion inside a single Performance Max campaign, plus YouTube brand channel linking and a new landing page text generation option.
