What Is Google Ads API v22?

Google Ads API v22 is the latest major release from Google, designed to give advertisers and developers direct, programmatic access to the newest features in Google Ads—often before they’re available in the standard UI. This isn’t just a routine update; it’s a significant leap forward, especially if you’re interested in automation, artificial intelligence, and more granular campaign control.

With v22, Google is pushing automation further than ever before, making it easier to create, optimize, and scale campaigns across Search, Shopping, Display, YouTube, and more. If you’re not using the API yet, this might be the version that convinces you to take the plunge.

Key Features in a Nutshell

Here’s a quick rundown of what’s new in v22—we’ll dig into each in detail below:

• Generative AI for asset creation: Automatically generate headlines, descriptions, and images.
• Smart Bidding exploration: Get time-segmented diversity metrics for Target ROAS strategies.
• Demand Gen campaigns: Expanded asset automation, new bidding options, and video generation from existing assets.
• Performance Max upgrades: Image enhancement, extraction automation, new reporting segments.
• App campaigns for installs: New “targetless” bidding goals for faster scaling without preset targets.
• Planning and reporting: Better audience insights, YouTube metrics, and trend reporting.

Generative AI for Ad Asset Creation

One of the standout features in v22 is the new AssetGenerationService. If you’ve ever spent hours brainstorming ad copy or sourcing images, this is for you. The API now lets you automatically generate text and image assets using Google’s latest generative AI models. That means fewer late-night creative sessions and more time focusing on strategy.

You can submit a few prompts or existing assets, and the system will spit out variations—headlines, descriptions, even image recommendations—tailored to your audience. This isn’t just about saving time; it’s about scaling creativity. If you’re running hundreds or thousands of campaigns, this kind of automation is a lifesaver.

The service is currently in beta, but early adopters are already reporting impressive results, especially for dynamic campaigns that need fresh creatives regularly.

Smarter Bidding: What’s New and How It Works

Bidding has always been a blend of art and science, and v22 leans hard into the science. If you’re using Target ROAS on Search, you can now retrieve time-segmented diversity metrics—basically, a deeper look into how your bids perform at different times or for different queries. This helps identify underperforming segments and adjust bids more precisely.

The API also introduces advanced simulation tools, letting you forecast outcomes before committing your budget. Want to see how changing your Target ROAS might affect conversions? Now you can test it virtually, reducing guesswork and wasted spend.

For developers, this means more data to play with and smarter automation opportunities. For marketers, it means better control and more confidence in your bidding strategies.

Demand Gen Campaigns: More Automation, More Power

Demand Gen campaigns (formerly Discovery) get a serious upgrade in v22. First, there’s expanded support for automated asset generation—so you can create design variations and even videos from your existing assets, all through the API. If you’re heavy into visual content, this is a big deal.

New bidding options are here, too. Specifically, you can now use Target CPC bidding for Demand Gen, giving you more flexibility in how you drive traffic and conversions. And with video generation baked in, you can repurpose static images into engaging video ads without a production studio.

These changes make Demand Gen a much more scalable option for brands looking to reach audiences across YouTube, Discover, and Gmail with high-impact creatives.

Performance Max Gets a Major Boost

Performance Max campaigns have been a favorite for many advertisers, thanks to their cross-channel reach and AI-powered optimization. With v22, they get even smarter.

The big news: campaign-level support for image enhancement and extraction automation. That means the system can automatically improve your images (think brightness, contrast, cropping) and even extract elements to create new assets. You also get new reporting segments and a feed_types field for more granular performance tracking.

If you’ve ever struggled to keep Performance Max creatives fresh or wanted more visibility into what’s actually driving results, these upgrades are a big step forward.

App Campaigns: Targetless Bidding for Faster Scaling

App campaigns—especially those focused on installs—get some of the most innovative features in v22. Google has introduced two new “targetless” bidding goals:

• OPTIMIZE_IN_APP_CONVERSIONS_WITHOUT_TARGET_CPA: Maximize in-app conversions without setting a specific target CPA.
• OPTIMIZE_TOTAL_VALUE_WITHOUT_TARGET_ROAS: Maximize total conversion value (including both installs and in-app actions) without specifying a target ROAS.

Why does this matter? If you’re scaling quickly, or if you’re not sure what targets to set, these options let the system optimize for volume or value without handcuffing you to a specific number. That’s huge for rapidly growing apps, seasonal surges, or markets where benchmarks are hard to pin down.

Existing target-based bidding options are still supported, so you’re not forced to change your strategy. But if flexibility is your priority, these new routes are worth exploring.

What’s Changing for Developers?

If you’re a developer, you’ll need to upgrade your client libraries and code to access some of these features. Google has published updated libraries and examples for all major programming languages, so the transition should be relatively straightforward—especially if you stay current with the latest releases.

There are also some deprecations to note: the call-only ad format is officially on the way out, with Google urging everyone to switch to Responsive Search Ads (RSAs) with call assets instead. RSAs offer more flexibility and better performance, thanks to Google’s machine learning, so the move makes sense.

Looking ahead, expect Google to continue accelerating its release cycle. Starting in 2026, the API will move to a monthly cadence—more on that later—so staying on top of updates is only going to get more important.

Common Questions and Concerns

Adopting new technology always raises questions. Here are some of the most common issues and how to address them:

Is It Complicated to Upgrade?

Upgrading is easier than you might think. Google provides updated client libraries and comprehensive migration guides. If you’re already running v21, the transition should be smooth for most use cases. If you’re coming from an older version, expect a bit more work—but the payoff in features and performance is worth it.

What Happens If I Don’t Upgrade?

You’ll eventually lose access to certain features, and over time, older versions are deprecated and no longer supported. Google’s standard support window is about a year for major releases, so you have time—but don’t wait too long.

Is There More Risk with Automation?

There’s always some risk when you let machines handle creative or bidding decisions, but Google’s AI tools are highly refined and used by millions of advertisers already. You’re never fully handing over the reins—you set the goals and guardrails, the AI handles the execution.

Do I Need a Developer to Use the API?

Many agencies and advanced teams have in-house developers or work with partners. If you don’t, there are plenty of third-party tools that expose API features through a UI. But if you want full control and the latest features, eventually you’ll need some technical help.

What About Data Privacy?

All asset generation and campaign management happens within Google’s ecosystem, so your data remains secure. As always, make sure you’re following best practices for access control and compliance.

How to Upgrade and Get Started

Ready to jump in? Here’s a quick checklist:

1. Review the release notes—see what’s new and what’s changed.
2. Update your client libraries—download the latest versions for your language of choice.
3. Test in a sandbox—experiment with new features before rolling them into production.
4. Migrate deprecated features—phase out call-only ads in favor of RSAs with call assets.
5. Train your team—make sure marketers and developers are up to speed on what’s possible.
6. Monitor and optimize—new features mean new opportunities. Keep an eye on performance and adjust as you go.

If you run into trouble, Google’s developer community and support channels are active and helpful. And if you’re serious about staying ahead, consider attending their webinars or joining their Discord channel for real-time updates.

Conclusion: What This Means for Your Business

Google Ads API v22 isn’t just another update—it’s a glimpse at the future of digital advertising. Generative AI, smarter automation, and more flexible bidding are no longer “nice to haves”; they’re quickly becoming table stakes for anyone who wants to compete at scale.

The platforms that win will be those that harness these new capabilities—automating the mundane, optimizing the strategic, and focusing human creativity where it matters most.
