Add an install prompt to WooCommerce
To add an install prompt on WooCommerce, paste the InstantPWA snippet into header.php (via WordPress) via Appearance → Theme File Editor → header.php, or WPCode. The popup captures the browser's native install signal where supported and falls back to a guided walkthrough on iOS Safari, so every visitor sees a clear path to installing your WooCommerce site as an app.
Steps
- 1
Open header.php (via WordPress)
Go to Appearance → Theme File Editor → header.php, or WPCode.
- 2
Paste the InstantPWA snippet
Drop the one-line async script tag in the WooCommerce head section — no build step or dependency install.
- 3
Configure the trigger
In your InstantPWA dashboard, set when the popup appears — on page load, after N seconds, or after a scroll/engagement threshold.
- 4
Publish
Save/publish in WooCommerce so the change goes live — most builders require an explicit publish step before custom code runs.
- 5
Verify on a phone
Open your live WooCommerce URL on a mobile device (not the editor preview) to confirm the popup renders.
Constraints to know
- Runs on any WordPress 5.0+ store; the snippet loads after WooCommerce's own cart-fragments.js, so there's no race condition reading cart state from localStorage.
- Compatible with both classic and WooCommerce Blocks (React-based) checkout since it never touches the checkout app itself, only the surrounding theme header.
FAQ
Does the install prompt work on iOS WooCommerce visitors?+
iOS Safari never fires the native beforeinstallprompt event, so InstantPWA shows a share-sheet walkthrough instead — visitors still get a clear add-to-home-screen path.
Will this conflict with other scripts on my site?+
No — InstantPWA is a single first-party async script with no third-party dependencies, so it doesn't block or compete with analytics or chat widgets.
Do I need to touch anything else in WooCommerce besides Appearance?+
No — the head snippet is the only integration point; InstantPWA hosts the manifest and service worker for you.
