How Event Deduplication Works
Browser and server versions of an event typically share a stable event ID and event name so the receiving platform can recognize them as the same action.
A Simple Example
A Purchase event sent by both the Meta Pixel and Conversions API uses the same event ID, allowing Meta to retain one conversion rather than count two.
Why Event Deduplication Matters
Using browser and server tracking together is valuable only when duplicate copies are reconciled correctly.
Common Misreading
Cross-channel deduplication and event deduplication solve different problems. Matching a browser event to its server copy does not decide which advertising channel deserves credit.
