Deduplication parameters for events are missing

[Fransiscus1]

Many events are not being deduplicated correctly. In event manager it says I need to add an event-id parameter to specific events on both the current pixel and the conversions API. how can I add an event-id parameter in the code of the conversions API of the Facebook Business Extension for magento 2? Or is there an other solution?

Hello @Fransiscus1, Are you still having this issue. If yes, please let me know the version of the extension that you are are using.

Hello @fbisaso, unfortunately, yes. We are using the latest version which is version 1.4.2

Hi @Fransiscus1 and @fbisaso, did you ever find a solution for this? We are having the same issue, our client is now paying double because of some deduplication issues. We are receiving the following error on FB dashboard:
"Event deduplication. Not meeting best practices."

Can you help?
