Aimerce now integrates OpenAI Ads Manager CAPI server-side

We have a new feature!

Aimerce now integrates with OpenAI's Conversions API so you can set up and verify server-side conversion tracking for ChatGPT ads directly from your dashboard.

Before that matters though, it's worth understanding what OpenAI has actually built in the last 90 days.

Again, 90 days. Not years!

OpenAI went from zero to ad platform in just 90 days

In February 2026, OpenAI began quietly testing ads on ChatGPT with a small group of brands on a CPM model. Advertisers paid per thousand impressions with no clear way to measure if the ads were actually working. Most performance advertisers were skeptical, and rightfully so.

Then in early May, OpenAI dropped the $50,000 minimum spend requirement, opened a self-serve Ads Manager to US advertisers in beta, launched CPC bidding at $3–$5 per click, released a Conversions API and JavaScript pixel for measurement, and announced expansion to the UK, Mexico, Japan, Brazil, and South Korea all within weeks.

Imagine how fast the launch was. Sounds like they were in a hurry to me. lol

For context on how fast this is, Uber didn't hire its first head of measurement until three years after launching ads. OpenAI is building measurement infrastructure almost simultaneously with the ad product itself.

This is OpenAI building the third major advertising platform on top of Meta and Google.

Why ChatGPT ads are different from Google and Meta

The difference comes down to intent quality.

Google infers intent from a search query. Like when someone searches "running shoes marathon training," Google knows they're likely interested in running shoes but it doesn't know their budget, how far along they are in the decision, or what else they're evaluating.

Meta models intent from behavioral signals, demographics, and past engagement. It builds a probabilistic picture of who might buy based on what they've clicked and liked.

ChatGPT on the other hand has explicit conversational context. When someone asks "what running shoes should I buy for marathon training under $150, I have flat feet and mostly train on roads" the purchase intent is stated, instead of being inferred. So that means that the decision has already been made.

Other than how fast they build everything in 90 days, OpenAI is targeting $2.5 billion in ad revenue in 2026, and $100 billion by 2030 which is clear to us that the platform being built for the long run.

ChatGPT has Pixel and CAPI but why those are not enough?

Alongside the Conversions API, OpenAI also launched a JavaScript tracking pixel. It fires a signal back to OpenAI's platform when a user completes an action on your site after seeing a ChatGPT ad purchases, leads, sign-ups, and more.

But the problem is, it's a browser-side JavaScript pixel. The same technology Meta, Google, and TikTok have spent years trying to move away from.

• Ad blockers kill it
• Safari deletes the cookies it depends on after 7 days
• iOS users are largely opted out of cross-app tracking
• Shop Pay and PayPal redirects break attribution at the exact moment a conversion happens

If you remember what it was like relying on the Meta pixel before server-side tracking existed, it's the same situation here. Pixel alone won't cut it. ChatGPT's pixel has the same limitations every other browser-side pixel has such as ad blockers, Safari, iOS. If any of that sounds familiar from your Meta days, the fix is the same which is server-side via the Conversions API.

That is why we built

→ New OpenAI CAPI setup page in your Aimerce dashboard connect and verify your integration in minutes, no developers needed

→ Click ID capture Aimerce captures OpenAI's click ID when a user arrives from a ChatGPT ad and persists it across sessions, so purchases are attributed back to the right campaign.

→ Spec-compliant payloads conversion events send customer fields and transaction amounts exactly to OpenAI's spec, so your data feeds their algorithm cleanly

If you're already on Aimerce for Meta or Google, this plugs into the same infrastructure.

ChatGPT Ads Manager beta is still rolling out gradually to US advertisers, so most brands don't have direct access yet but this is the right time to get tracking in place is before your first campaign.

And honestly, if you can get into the beta, just test it. Bids are cheap right now ($3-$5 CPC) and for sure you'll learn more from a small run than from anyone's prediction about how it performs.

If Meta or Google isn't reporting your Shopify orders accurately right now, probably worth cleaning that up before adding another channel into the mix.
