Google Ads API v23 brings PMax data, richer invoicing, scheduling

Google released v23 of the Google Ads API, the first update of 2026. It marks the start of a faster release cadence.

What’s new. The update adds deeper Performance Max reporting, more granular invoicing, AI-powered audience tools, expanded campaign controls, and more:

• Performance Max transparency: Ad network type breakdowns are now available for PMax campaigns.
• More detailed invoices: Campaign-level costs, regulatory fees, and adjustments can be retrieved via InvoiceService.
• More precise scheduling: Campaigns can now use start and end date-times instead of date-only fields.
• Local data access: Store location details are available through PerStoreView, matching the Stores report.
• New audience dimension: LIFE_EVENT_USER_INTEREST enables life-event-based audience building in Insights tools.
• Smarter Demand Gen planning: Conversion rate forecasts now vary by surface (e.g., Gmail, Shorts).
• Generative AI audiences: Free-text audience descriptions can be translated into structured audience attributes.
• Expanded Shopping metrics: New competitive and conversion metrics are available by conversion date.

Why we care. A faster update cycle lets advertisers and developers access new capabilities sooner, especially as Google pushes deeper into automation, AI-driven planning, and cross-campaign visibility.

Plan for upgrades. Some updates require upgrading client libraries and code, so teams may need to plan development time to fully benefit from v23.
