The request
“We're seeing deduplicate errors on our Facebook pixel. Events come through twice and Meta flags them. We need it resolved.”
Double-counted events hurting ad performance.
The approach
We aligned the event identifiers between the browser pixel and server events so Meta recognizes them as one, and verified deduplication in Meta's tools.
What we shipped
Browser and server events deduplicated
Verified in Meta's event tools
Event match quality improved
