Greetings!
Here is my situation.
I want to install a Facebook Pixel for my Checkout pages. i am only selling digital products which is pdfs and they are 8 in total. so i have 8 checkout pages. i don’t have a shopify store and i only use the buy button. i just created pages in my website and applied the buy button.
How can I install Facebook Pixel in my checkout pages?
Thanks and regards.
