iOS blocks conversion tracking

Since Apple introduced iOS 14 privacy controls, ad tracking has changed permanently. As more customers online opt out of tracking, traditional browser pixels degrade and ad performance suffers significantly.

Ad blockers hide customer actions

For e-commerce brands, the pressure is mounting as cookieless browsing and ad blockers become the new default.

Cookie restrictions blindfold the attribution

Without accurate tracking data, the feedback loop to ad network algorithms (Meta, TikTok, Pinterest, others) is severed. The AI stops learning who your real buyers are and starts guessing. That is where ROAS collapses.

Why merchants benefit from Checkify integrations

FAQs

Find answers to common questions about optimizing your ad tracking, scaling ROAS, and boosting conversions with Checkify checkouts.

CAPI and pixel tracking: what is the difference?

Traditional browser pixels rely on third-party cookies stored on a customer's browser, which are increasingly blocked by ad blockers, privacy settings, and operating systems. CAPI enables sending of purchase data directly from Checkify’s server to the ad platform’s server. Combining both technologies ensures high data accuracy (over 90%) and recovers lost signals.

I still want to use my ad tracking app. Is it possible with Checkify?

Yes. You can easily add custom scripts to your checkout and thank-you pages. Many of our merchants continue using third-party solutions, like Triple Whale or Wetracked, to expand their tracking and analytical stack.

How hard are the integrations?

Checkify provides seamless integrations designed for quick setup. You can easily plug in your pixel IDs, access tokens / event IDs from your ad & marketing platforms straight from your Checkify dashboard without needing custom server code. We take care of the rest.

I would like to connect several Facebook pixels, is it possible?

Yes, you may add a primary, a secondary (back-up) pixels to Checkify. Conversion events will fire across all assigned pixels, keeping all your Meta ad accounts populated with accurate data.

Why do my pixels work in test mode, but miss real customer events?

Many of your customers shop using ad blockers, strict privacy settings, or private browser modes, which block traditional browser pixels from firing. Activating server-side Conversions API (CAPI) for your Checkify checkouts bypasses these browser limitations, passing purchase signals directly to your ad platforms to restore data accuracy and feed their optimization algorithms.
