Is it possible to report CRM events as conversions?

Trying to improve the accuracy of data being sent back to Facebook. Is Pixel + Capi the best setup? Or is it possible to loop CRM events back into FB using offline conversions? Does anyone know?

Pixel + Capi is the tried and tested setup and if it suits you just fine, then you probably don't need to deviate from it.
Also, I'm pretty sure there's a way to track your leads with FB offline conversation. Not sure if that's exactly what you're looking for but it's worth checking out.
