Facebook Lead ads now allows you to optimise towards "Conversion Leads" which is where Facebook will optimize towards people who convert deeper in your funnel (and not just filled in a Lead form).
In order for this to work we need to map the "ID" field to a contact field in GHL, so that it can be passed back to Facebook when a deeper conversion occurs (like they fill in a form, make a purchase or book a call). (The "ID" value is a 15-16 digital unique number that is generated when someone completes a Lead Ad and is sent as part of the payload).
Zapier gives us access to this ID field so I can do this through Zapier, but right now Highlevel Lead Ads integration doesn't. What we need is for Highlevel to allow us to access the 'ID' field and map it to a custom contact field. Then when a conversion occurs, we can send it to Zapier via webhook, which then passes that data back to FB telling them the lead ID has converted.
