Looking for someone who could correct my s2s + facebook pixel setup

Hi I'm looking for someone to fix my s2s + facebook conversions api set up, I'm an affiliate on a gambling platform and I use keitaro as a tracker and myaffiliates are the one they use for postbacks. My set up with keitaro seems right since it shows Leads(registers) and sale(FTD). However it doesn't send a "purchase" data on my facebook pixel. Thank you
