I'm trying to implement a custom event with Facebook Pixel and Facebook Conversion API, but I have a problem with the deduplication process.
I read in the documentation that:
We determine if events are identical based on their ID and name. So, for an event to be deduplicated:
In corresponding events, a Facebook pixel's eventID must match the conversion API's event_id. In corresponding events, a Facebook pixel's event must match the conversion API's event_name.
I set correctly the event name and id in both cases (pixel and conversion api) but it's not working 100%. Sometimes my events are deduplicated, and sometimes not.
Here is a screenshot to understand better: Test events
Thank you for your help!
