How do I fix duplicate purchase events in my Facebook Ads Manager?

Duplicate Facebook purchase events occur when both your browser-side Meta Pixel and server-side Conversions API (CAPI) report the exact same checkout transaction without matching unique event ID parameters for automatic de-duplication.

“Most minor website breaks are caused by simple script conflicts, legacy code blocks, or broken API handshakes. We identify and clear these issues immediately as a straightforward, one-time fix.”
