Google has released v23 of the Google Ads API, the first update of 2026 and the start of a faster release cadence, introducing deeper Performance Max reporting, more granular invoicing, new AI-powered audience tools, and expanded campaign controls.
What’s new:
- 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 quicker update cycle means advertisers and developers will get new capabilities sooner, especially as Google leans further into automation, AI-driven planning, and visibility across campaign types.
Between the lines. Some of these updates require upgrading client libraries and code, meaning that teams may need to plan development time to take full advantage of v23.
Bottom line. Google Ads API v23 sets the pace for 2026, pairing faster releases with more AI-driven insights, better reporting, and tighter campaign control for advertisers building at scale.
