Nadarh is one line added once at store level. Where it is pasted, and the form the line takes, differ by platform — this page covers each one separately. Your theme stays as it is; so does your cart.
For fields that accept HTML tags: Google Tag Manager, Shopify, WooCommerce, Wix.
<script src="https://nadarh.ai/nadarh.js" data-merchant="STORE" defer></script>
For fields that accept JavaScript only, no tags: Salla “Advanced customization”, Zid custom code.
window.NadarhConfig={merchant:"STORE"};(function(d,s){s=d.createElement("script");s.src="https://nadarh.ai/nadarh.js";s.defer=true;d.head.appendChild(s)})(document);STORE is your store id; we send it after calibration. Nothing else in the line changes.
We read each platform’s documentation and checked live stores. These are the routes that actually exist, and what each needs.
We measure each shade from its photo so it shows on the face as it does in real life.
From your platform’s product id. On every other page it does nothing.
It finds the cart button on Salla, Zid, Shopify, WooCommerce and most themes.
Nothing stays in your store.
Five things on day one; we come back with the line within two working days.
Half of the visitors to the pilot pages see the button, half don’t — same days, same campaigns. You compare your own store numbers; we send you ours every week.
Does the button earn its place?
Does she trust it? (she can upload a photo instead)
Did the analysis complete in good light?
Did she engage with the shades?
Did trying lead to buying?
The line adds one button and touches neither theme, cart nor checkout. We checked the security headers on live Salla stores: no restrictions on external scripts or on the camera.
Analysis and try-on run in her browser; no photo is uploaded.
A random session id, the store, the product, the shade she tried or added, and her skin reading as a few words and a number. No name, no email, no account. You see aggregate numbers only.
