Facebook Pixel

Edge cases + gotchas

  • Ad blockers and iPhones hide many browser events — add the Conversions API token.
  • Cookie Consent delays the browser pixel until visitors allow Marketing cookies; reported numbers drop.
  • Test event code left in — events keep going to Test events; clear it after testing.
  • Wrong Pixel ID format — ignored silently; double-check the number.
  • Failed online payments aren't sent as purchases from the server; the browser may still report one if the shopper reached the confirmation page.
  • Orders you create in the admin or POS don't fire browser events.
  • Several pixels — only one Pixel ID is supported. Add extra pixels with Tracking Scripts if you must.
