Installing Facebook Pixel & Google Tag

Hi community, does anyone know how to install tracking codes like Facebook Pixel and Google Tags into the website?

Thank you in advance.


it’s not working,
is there more than one tracking code that can work.
I already add the google-analytics tag here in the HTML head tag but I want facebook pixel code too. but when I add the code its not track the audience.

I am probably wrong, but can’t you add a bunch of pixels to the GA tag and then put that tag in ERPNext? ← I will try to test this on my own later today.
