Use Conversion API
-
Yes l’m currently focused on improving my skills around website design, funnels, and conversion optimization, mostly through hands-on projects and continuous learning.
I’ve been applying that by working on things like website design, sales funnels, Shopify store setup, and lead generation systems basically helping businesses not just build pages, but improve how they convert visitors into leads or customers.
Always open to learning more and definitely appreciate the support 🙌

Api for sure no debate

Use both if you can. Pixel alone misses a chunk now with iOS and blockers.
When I tested, CAPI filled in like 10 to 30 percent more conversions, but also brought in some noisy data if not deduped properly.
Pixel is still useful for real time signals, CAPI just patches the gaps. Setup matters more than which one you pick.

conversion api is basically pixel but it actually works now that everyone has ad blockers and safari exists. so yeah, it makes sense.

The recommendation is both actually. The platform dedupes in the back end.

No CAPI is life on hard mode

Yes, you get much better quality signals for billing optimization when you use Conversion API and similar server-side event tracking. Make your life easy by using, whenever possible, tracking code managers that do the heavy lifting for you, like setting valid event IDs for the duplication etc.

It was awhile ago when I ran pixel-only and thought everything was fine until results got inconsistent. The issue is the pixel depends on the browser, so ad blockers, iOS privacy stuff, and even slow page loads can drop events. That means the platform is optimizing on incomplete data.
Adding Conversion API basically gives you a second path for sending the same events, but from your backend. When both are deduplicated correctly, you get a more complete picture of what’s actually happening. It’s not magic, but it does reduce those weird gaps where you see sales but ads manager doesn’t.
Just make sure it’s set up clean. If events aren’t deduplicated properly, you can mess up your data instead of improving it. Once it’s stable though, it usually helps especially if you’re spending consistently.
