Conversions API (Event missing Some Duplication Parameters)

Technical Q&A
1

I found many people faced the same problem but without found a solution for this!

Conversions API installed through Facebook Channel App.

Firstly, I set the Data Sharing Setting to “Maximum”, and I faced the known error message (Event Missing Some Duplication Parameter) for ContentView, InitiedCheckout and Purchase events.

I read a guy set the Data Sharing Setting to “Standard” and he said the message disappeared. But as you know the “Standard” don’t send Data to Facebook through “C API”, but just through the Pixel.

Does anyone found a fix for this bug?

I really appreciate any help/ Thank you

Thank you for bringing this to our attention. The warning message has been resolved by Facebook. You should no longer see the “missing some duplication parameters” warning in Events Manager when selecting the maximum data sharing setting.
