Squarespace installation guide

  1. Confirm your Squarespace plan includes Code Injection. Copy the site's script snippet.
  2. Open the site-wide Code Injection settings, paste it into Header and save. Use the site-wide field rather than one page's header.
  3. Visit the live public website, with required consent granted, and click Verify installation. Editor previews can suppress custom scripts.

Install once. Code blocks and checkout confirmation snippets are different surfaces and do not cover every page. Connect supported payment webhooks separately for revenue; do not store private payment credentials in Squarespace custom code.

Official reference, checked 2026-10-26: Squarespace Code Injection.
