Google says its move to two Google Ads API releases a month from version 26 brings no extra migrations. I believe that, and I still think most marketing teams are underprepared for it.
The facts come from Google’s own announcement. In a post dated Oct. 12, 2026, Anash P. Oommen of the Google Ads API Team wrote that the API will ship two releases a month starting with v26. The schedule table runs from v26 in October 2026 to v30.3 in December 2027, 25 versions in all and 21 of them in 2027. Major releases stay at four a year. Minor releases, in the post’s words, “add only new, non-breaking features.” Oommen added that sunset dates are unchanged, “so you will not need to migrate more often.”
The strongest counter-argument
The best case against my position is that non-breaking minor releases cost nothing. A team can ignore them, stay on a pinned version, and move once a year when its major version nears sunset. For a team that already has the fields it needs, that is a sound plan, and Google’s guarantee supports it.
Why I still disagree
Google gave a reason for the faster cadence: it wants to give “automated agents and workflows” earlier access to features. A team that sells or runs agent workflows on top of the Google Ads API competes on how quickly it can use what Google ships. For that team, ignoring minor releases is a product decision, and it should be made on purpose.
The second problem is how teams will find out. Google says release blog posts and YouTube live events will move to twice a quarter, each covering several releases at once. For individual releases, the post tells developers to save the release notes page, which notifies them when it changes. The explanation of each release now sits in a reference page, and the job of noticing falls to the developer.
The third problem is that the schedule is a forecast. Google calls the dates estimates and says it may add or remove releases, or switch a release between major and minor. A minor that becomes a major changes the sunset arithmetic for everyone who skipped it.
The cadence has also changed before. In a post dated Sept. 4, 2025, Google moved the API to monthly releases starting in January 2026 and raised the number of major releases from three a year to four. That is two changes in 13 months. Any internal process built around today’s rhythm needs to survive a third.
Taken together, these points move the work from migrating to reading. The migration count stays at four a year. The reading load goes from roughly one release note a month to two, and in 2027 the table shows 21.
Marketing teams that never touch the API directly are affected too. Their agency, their reporting vendor and their bid-management tool all build on it. Each of those vendors now has a heavier reading load, and a customer can reasonably ask how it tracks releases and how quickly a new field shows up in the product. A vendor that has a named owner will answer in one sentence. A vendor that does not will take a week to find out.
What I would do this week
- Name one owner for Google Ads API release notes and give that person a fixed slot for each release.
- Pin the client library version and upgrade on a schedule that matches Google’s twice-a-quarter release posts.
- Keep a sandbox account and run a smoke test of your five most important reports against every minor release.
- Keep a short log of new fields you decided not to adopt, so that a decision to skip is written down.
- If you run a martech product on this API, tell customers which API version your integration uses, and ask your own vendors the same.
Vendors choose how often they ship, and the integration team decides how often the change reaches production. Both v26 and v26.1 are scheduled for October, so the owner should be named before they land.
