Facebook Pixel Affiliate/Sweeps Trakaff

Hi,
Does anyone know how to accurately track Purchases on FB Ads

The structure is:
Landing page on Funnelish (installed Pixel here)
When customer click "BUY NOW" they get redirected to affiliate offer (cc blanks sweeps) from Trakaff.

I want FB to show Purchases in ads manager campaigns when someone submit their cc so I can scale and optimize.

Trakaff have postback and I connected pixel but it only shows in events manager, not in ads manager..

Anyone have solution please?

Use Facebook’s Conversion API (CAPI) – Since the purchase happens offsite (on Trakaff), you need server-side tracking to send purchase events back to Meta.
Check Postback URL Settings – Ensure Trakaff’s postback fires a Facebook event with the correct parameters (Purchase event, Value, Currency, etc.).
Use a Third-Party Bridge – Tools like RedTrack, Voluum, or Binom can sync conversions from Trakaff to Facebook Ads Manager.

the issue is that trakaff’s postback only sends events to events manager but doesn’t link them to Ads Manager. The fix: use conversion API (CAPI) + pass fbclid from funnelish to Trakaff, then send it back in the postback. If Trakaff doesn’t support CAPI, create a Custom Conversion based on the offer URL. This way, Ads Manager will track Purchases properly so you can scale
