Manage snippets for Square Online sites.
The Snippets API lets you manage snippets that add custom functionality to Square Online sites. A snippet is HTML, CSS, and JavaScript that is injected into the head element of all pages on a site, except for checkout pages. You can use the Snippets API to create applications that help meet the many needs of Square sellers.
