Not a dumb question at all, this actually happens a lot when you’re running both Meta Pixel and CAPI through Zapier. The 7% overreporting is usually because Meta is getting the same sign-up event twice (once from the browser pixel and once from the server), but Zapier doesn’t always send the event\_id, so Meta can’t deduplicate them properly. I had the same issue a few months ago. I was constantly seeing Meta report more conversions than I actually had in my backend. Turned out it was all about duplicate and mismatched events. I ended up switching to Tracklution for my server-side tracking setup. It connects directly to Meta’s CAPI, automatically sends deduplicated events with the right parameters, and even shows you a validation dashboard so you can see if Meta is over or under-reporting. Since switching, the data between Meta and my backend is almost perfectly aligned. So yeah, it’s not normal variance, it’s a setup thing. If you stick with Zapier, you’ll probably need to add the event\_id logic manually.
