Why this is more involved than a normal pixel
On a normal e-commerce site the pixel fires on your own checkout page. With OnlyFans, the subscription and payment happen on onlyfans.com — a domain you don’t control and can’t put a pixel on. So conversions are sent to Meta server-side, via the Conversions API, from a tracked landing page that carries the visitor’s match keys. That’s the whole point of the setup guide — and why it comes before you launch a single ad.
Start with the setup
You can’t track or optimize ads until the pixel is live. Knock out the setup, then launch.
