Social media, flags and custom scripts
Social media
Section titled “Social media”Under Theme settings → Social media, paste the address of each profile you have: Instagram, Facebook, X, Pinterest, TikTok, YouTube, LinkedIn, Snapchat, Telegram, Tumblr, Reddit, Twitch, Discord and Spotify. Every place that shows social links reads from here: the footer blocks, the overlay menu, the password page and the contact form. An empty field simply shows no icon. Icon style is the bare icon, or an icon in a circle or a square.
Localization
Section titled “Localization”Flag shape sets the shape of the country flags in the country selectors: square, rounded or circle. Which countries and languages appear comes from Settings → Markets in your Shopify admin.
Custom scripts
Section titled “Custom scripts”For tracking pixels, chat widgets and other code a third party gives you. Paste it exactly as they provide it into Code in the page head or Code at the end of the page, and it is added to every page. Shopify’s own pixels and analytics do not need this; add those under Settings → Customer events.
