Has anyone implemented the Snapchat Pixel on their site with custom event parameters? I have placed the 'Page View' pixel in the <head>, but am seeking to create bottom-of-the-funnel events ('Add to Cart', 'Initiate Checkout', 'Purchase' etc.), but don't understand how to implement the code across specific pages on my site. Is this possible on Squarespace? What is the proper code to enable the pixel to fire on specific actions?
