Fecbook Api Pixel

I need to send events directly from our web server in wordpress to Facebook Business manager through the server-side API, token access is already done. pixel is created . we have clicks to 3rd party websites that we want to measure conversions from to our Facebook business manager where we run ads .we already have pixelyoursite integrated in our website in Wordpress .
I need someone who can make it for me and teach me how to do that in the future for another ad account in our facebook business manager as i will need multiple pixels there .
