Meta Conversions API: Deduplication Not Working
- 1
Compare the browser and server copies in Test Events for event_name, event_id and event_time.
- 2
Create the event ID once in the customer journey and pass it unchanged to both implementations.
- 3
Remove duplicate server retries or browser triggers, then retest one clean conversion.
WHAT THE ERROR MEANS
The two sources describe the same action with mismatched identifiers or multiple copies.
Meta cannot deduplicate browser and server events when their names or event IDs do not match within the expected window.
