Discrepancy in Meta Conversions API via Zapier – More Leads Than ExpectedHi Zapier friend,Has anyone experienced inconsistencies when using the Meta Conversions API through Zapier?Here’s the setup: I use Zapier with Webhooks to send conversions to Meta from Systeme.io opt-in pages (I don’t use Facebook Lead Forms on all funnels — this is intentional). Only a “View” Pixel event is triggered on the opt-in page, to keep tracking clean. All conversions are sent via the Conversions API only (no duplicated pixel events). Zapier is correctly sending the data — everything looks good, no errors on the Zap side. 👉 The issue: Meta is showing 25 “Tabac” leads, but I only have 3 real contacts in Systeme.io.I’m investigating, but if anyone has encountered this kind of discrepancy — or knows what might cause such a mismatch — I’d love your insights 🙏Thanks a lot in advance!

Discrepancy in Meta Conversions API via Zapier – More Leads Than Expected

Hi Zapier friend,

Has anyone experienced inconsistencies when using the Meta Conversions API through Zapier?

Here’s the setup:

I use Zapier with Webhooks to send conversions to Meta from Systeme.io opt-in pages (I don’t use Facebook Lead Forms on all funnels — this is intentional).
Only a “View” Pixel event is triggered on the opt-in page, to keep tracking clean.
All conversions are sent via the Conversions API only (no duplicated pixel events).
Zapier is correctly sending the data — everything looks good, no errors on the Zap side.

The issue: Meta is showing 25 “Tabac” leads, but I only have 3 real contacts in Systeme.io.

I’m investigating, but if anyone has encountered this kind of discrepancy — or knows what might cause such a mismatch — I’d love your insights

Thanks a lot in advance!
