Meta Pixel: event_id Is Missing
- 1
Generate one unique ID when the conversion action occurs, not separately in each destination.
- 2
Send that exact value as eventID in the browser call and event_id in the server payload.
- 3
Verify both sources appear as one deduplicated event in Events Manager Test Events.
WHAT THE ERROR MEANS
Browser and server events cannot be matched because they use no shared event identifier.
An event_id is required to deduplicate matching browser and Conversions API events reliably.
