The auction runs on Meta's estimate of who will buy, and that estimate is only as good as the purchase data you send back. This is the official spec for sending it server side instead of relying on the browser pixel alone.

Running pixel and CAPI together without matching event_ids just means you're double counting, not building redundancy. This page is the fix.
From
Meta for Developers
Explains exactly how Meta deduplicates a browser event and a server event: same event_name and same event_id within 48 hours
event_id must be an identical string on both sides, an order ID or generated UUID both work as long as they match
Shows what 1 event from 2 sources versus 1 event from 1 source means inside Events Manager, the fastest health check for your setup
