Hello,

 

i actually use the Facebook pixel, and now the API with zapier. The problem is duplicated event on my Facebook… how can I resolve this? 

Hi @Julien!

According to Facebook, for events to be deduplicated, you or your developer should add 2 event parameters that help us determine if the events are the same: the event name (for example, Purchase or AddToCart) and the event ID. 

See here: https://www.facebook.com/business/help/823677331451951?id=1205376682832142 

The way I understand that is that you would need to use the same event name and event ID in both the Zap and in Facebook Pixel, for those events to be deduplicated by Facebook app.

More detail here from Facebook: https://developers.facebook.com/docs/marketing-api/conversions-api/deduplicate-pixel-and-server-events#event-deduplication-options

The trick is that the trigger for the Zap would need to provide that event ID. There was a similar question here with some suggested solutions from the Community: 

 

Hope that helps!
