Google has released Google Ads API v24.2, an update that introduces new security controls, AI transparency features, enhanced reporting capabilities and additional experiment types for advertisers and developers.
What’s new. The headline feature is support for multi-party approvals (MPA), which requires a second administrator to approve sensitive account actions such as user invitations and access-level changes. The feature adds an extra layer of security for agencies and large organizations managing Google Ads accounts.
Google is also expanding support for AI-generated content disclosures. The API now exposes new SyntheticContentInfo and SyntheticContentAttestation fields on assets and ads, allowing developers to identify and label AI-generated creative programmatically. The update is designed to help advertisers prepare for the EU AI Act, which takes effect on August 2nd
Developers can begin building integrations now, although advertiser attestation fields remain read-only until the launch of v25.

Performance Max gets more visibility. Version 24.2 adds several long-requested enhancements for Performance Max campaigns, including the ability to segment performance_max_placement_view reports by ad_network_type. That gives advertisers a clearer picture of where ads are appearing across Search, Display and partner networks.
The release also introduces YouTube brand channel linking through the API, enabling stronger integrations for video campaigns, along with a new landing page text generation option that can automatically create text assets from a website’s landing page.
New testing capabilities. Google is expanding experimentation tools with two new experiment types.
The new COMPARE_CAMPAIGNS workflow allows advertisers to compare multiple campaigns or campaign types across as many as five experiment arms, including custom Performance Max experiments.
A second experiment type lets advertisers test text customization and final URL expansion within a single Performance Max campaign by splitting traffic between variations.
Documentation improvements. Google has also reorganized its API release notes, separating breaking changes from feature updates and introducing a dedicated guide for feature deprecations and unversioned changes to simplify future upgrades.
Why we care. While the release doesn’t include ground breaking changes, it gives developers new tools to prepare for upcoming AI disclosure requirements, strengthen account security and gain deeper insights into Performance Max campaigns.
The bottom line. Google Ads API v24.2 is a straightforward upgrade from v24.1, but it introduces meaningful features for advertisers preparing for AI transparency requirements, improving account security and getting more actionable reporting from Performance Max campaigns.
