Google has released version 26 of the Google Ads API, and said the Ads API will now be updated twice a month for the rest of this year and into 2027 — double last year’s monthly cadence. Search Engine Roundtable reported the version 26 release on October 15 and the cadence change on October 16; Search Engine Land’s coverage of v26 highlights Search Lift measurement and new campaign controls among the headline features.
Version 26’s feature list includes streamlined EU political advertising declarations, vertical-agnostic travel bid modifiers, Search Lift measurements, Local Services Performance Max campaign creation, a unified enhanced conversions configuration, and Shopping and Demand Gen enhancements. Google has published updated client libraries and code examples with the release. The version history shows how fast the API already moved — v25 in July with minor releases in August and September — and the twice-monthly schedule will compress that further for the teams and tools that build on the API.
Why it matters: for agencies and software vendors, the Google Ads API is the product underneath the interface — reporting, bidding and campaign construction all depend on its version support windows. Doubling the release cadence means new features, like the Demand Gen changes covered in Google Ads Automated Promotions Are Live, can reach API users sooner, but migration and testing work doubles too. Advertisers who never touch the API still feel it through the tools they use, which must keep pace with releases like the controls in Google Ads Adds Channel Prioritization And Budget Allocation Controls.
