Facebook lead conversion missing parameters

As per the instructions on getting lead events in Facebook, I’ve successfully triggered them. However, parameters are missing from the payload…namely lead_event_source and event_source

I’ve followed the instructions exactly and even checked my payload from Zapier matches the one for the Facebook integration. Unsure what the issue is but I cannot proceed without it.

Hi @designedbyiman 

Welcome to the Community! I'm sorry you’re having trouble with your Zap.

Have you selected the most recent sample trigger from the Facebook trigger step?

Thanks Brem - appreciate the quick response.

Yes, in fact I have sent 4 transactions through and they all appear find.

The only thing missing is the parameters.

Here is an example on the Zapier side...

Hi @designedbyiman,

You are most welcome!

I have created a new topic for the issue you raised about the new lead not triggering the Zap. This is because it is a separate issue with another Zap you have. I have replied to the issue in this post:

We can continue troubleshooting the issue on that post.

Thanks! 😊

Hi @ken.a 

I’m having this some parameters issue since May. I’m sending the Event_id and External_id, but they are arriving on Facebook as information fields not parameters, so de deduplications it’s not possible. 

It’s something regarding with this bug that you mentioned?

Unfortunately, I'm experiencing the same issue today, where some fields are correctly included and others are not. This is very unfortunate. If possible, would it be possible to add my email address to be notified when the issue is resolved?
