Complete coding illiterate here so forgive my incompetence.
Trying to install Facebook Pixel in my store, would simply copy & pasting my pixel code into here work?
Any help and advice are greatly appreciated.
I believe that by pasting the Pixel code Facebook gives you from the <!-- Facebook Pixel Code -->
to the <!-- End Facebook Pixel Code -->
would paste the relevant code before the header, and providing you follow the rest of the documentation here you should be fine. Best of luck. I should note that use the code that Facebook gives you, not the below code I've left this in for other developers to read.
<!-- Facebook Pixel Code -->
<script>
!function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n;
n.push=n;n.loaded=!0;n.version='2.0';n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window,
document,'script','https://connect.facebook.net/en_US/fbevents.js');
// Insert Your Facebook Pixel ID below.
fbq('init', 'FB_PIXEL_ID');
fbq('track', 'PageView');
</script>
