Send web push notifications from Squarespace
Web push on Squarespace works through the same InstantPWA snippet you add for install prompts — placed in Code Injection → Header via Settings → Advanced → Code Injection → Header. Once a visitor opts in, you can send push notifications from your InstantPWA dashboard to anyone who granted permission, including installed home-screen users on iOS 16.4+.
Steps
- 1
Open Code Injection → Header
Go to Settings → Advanced → Code Injection → Header.
- 2
Paste the InstantPWA snippet
Drop the one-line async script tag in the Squarespace head section — no build step or dependency install.
- 3
Enable push in your dashboard
Turn on Web Push in InstantPWA settings and upload your notification icon and default badge.
- 4
Publish and collect opt-ins
Once live on Squarespace, the popup asks for notification permission after install (or standalone, if you enable prompt-first push).
- 5
Send a test push
Send a test notification from the dashboard to your own opted-in browser before sending to all subscribers.
Constraints to know
- Code Injection requires a Business plan or higher — Personal plan sites cannot add custom scripts at all.
- Squarespace strips code injection from the mobile app editor preview; test on the published desktop or mobile browser URL.
FAQ
Does web push work without the visitor installing the app?+
On Chromium browsers and desktop, yes. On iOS Safari, push requires the visitor to add the site to their home screen first (iOS 16.4+).
Can I segment who receives a push?+
Yes — the InstantPWA dashboard supports targeting by page visited, device type and custom events you send from your site.
Is there anything Squarespace-specific I need to configure for push?+
No — push registration is handled entirely by the InstantPWA snippet once it's live on Squarespace; there's no separate push API key to manage.
