Fix Meta CAPI + Stape + Make.com Tracking (Purchase Event Not Showing)

Looking for an expert who understands Meta Conversions API, Stape (CAPIG), and Make.com inside out.

I’ve already set up the integration and can get a 200 OK response, but the Purchase event isn’t appearing in Meta Events Manager.

I need someone to quickly troubleshoot and fix the setup — ideally within the next hour.

You should be able to:
Identify why the event isn’t showing despite a successful 200.
Check the connection between Make → Stape → Meta Pixel (CAPI).
Ensure that all parameters (event_time, user_data, event_id, etc.) are properly formatted and processed by Meta.
Verify deduplication with browser Pixel (if needed).
This should be a quick fix for someone who knows what they’re doing.
Deliverable:
Fully working Meta purchase tracking — showing as a server event in Events Manager under my Pixel ID.
Thank you.
