Give every shopper a fitting room, directly on your Shopify product pages. One script tag in theme.liquid and you are live in minutes, no developer needed.
In your Shopify admin, go to Online Store, then Themes. Click the three-dot menu next to your active theme and choose Edit code. Open the theme.liquid file.
Paste the snippet below just before the closing </body> tag. Replace YOUR_KEY with your OnFitt API key from your dashboard.
<script
src="https://getonfitt.com/sdk.js"
data-api-key="sk_live_YOUR_KEY">
</script>Click Save in the top right. That is it. OnFitt appears automatically on every product page in your store.
No reshoots, no uploads, no catalog work. OnFitt reads your existing product images automatically.
OnFitt loads asynchronously and only activates when a shopper clicks the button. No effect on Core Web Vitals.
OnFitt opens in a full-screen modal overlay. No redirect, no third-party page. Your brand stays front and centre.
