API Pixel setup for Indiegogo Pre Campaign. Connect my Facebook pixel to my Indiegogo campaign.

This is a simple job if you have done something very similar before. The last two freelancer tried but could not make the pixel work.
I need to know where and who the people signed up for my Indiegogo campaign come from etc. That’s what pixel API tracking is for. So before I can pay you, I need to see exactly where my Indiegogo customers come from.
