API version 1.0 — Last updated June 2026

Add size recommendations to your store in three steps.

  1. Create a brand account at fitld.com/signup
  2. Go to the Integration tab in your dashboard and copy your Widget ID
  3. Paste the script tag below just before </body> on your product page
Basic script tag
<script src="https://fitld.com/fitld-widget.js"
  data-widget-id="wgt_YOUR_WIDGET_ID">
</script>

The widget loads silently — no button appears until you add data-attach-to or use one of the modes below.
