Meta Pixel: Duplicate Events Detected
- 1
Use Test Events to identify the event name, source and duplicate timestamps.
- 2
Remove duplicate GTM, plugin or hard-coded triggers so the browser event fires once.
- 3
For browser plus Conversions API, send the same event_name and event_id from both sources.
WHAT THE ERROR MEANS
Multiple implementations or missing deduplication keys make one user action look like several events.
Duplicate events appear when the same action fires more than once or browser and server events cannot be deduplicated.
PRIMARY DOCUMENTATION
