JavaScript Referral Program Integration

You add the Referral.js snippet to your site or app with a single script tag, then call its methods to track conversions or render referral UI. Step-by-step installation instructions are in the Referral.js SDK documentation.

Referral.js lets you capture referral events on any page (page load, form submit, checkout, or custom triggers), create referrals from on-page events or URL parameters, embed the Member Portal or Share Widget directly in your platform, and measure the traffic your members generate, all client-side, with no backend changes for standard flows.

Many of our platform integrations, including Shopify, WooCommerce, Webflow, Wix, Squarespace, and most form builders, use Referral.js under the hood to track conversions. If you're connecting one of those specific platforms, the exact snippet placement and setup are covered in that platform's own integration documentation. This page covers the underlying library for custom or direct implementations.

It takes minimal dev resources. Pasting the snippet and tracking a simple conversion is straightforward, but custom event tracking or embedding the portal in your app is best handled by a developer. Concierge Onboarding is available on all plans if you'd like hands-on help.

The full Referral.js SDK reference, covering installation, tracking methods, and embedding options, is available in our Referral.js SDK documentation.
