Install + identify

The SDK does three things: track page loads (which capture ?ref= and refresh the cookie), identify users when they sign up or log in, and emit revenue events.

Install

npm

npm install @openpartner/sdk

import { OpenPartner } from '@openpartner/sdk';

export const op = new OpenPartner({
  siteId: 'site_xxx',
  // optional: override the router URL for self-hosted deploys
  routerUrl: 'https://r.yourdomain.com',
});

CDN

<script src="https://cdn.openpartner.dev/sdk/v1.js"></script>
<script>
  window.openpartner.init({ siteId: 'site_xxx' });
</script>

Track

Call once on every page load. It reads ?ref= from the URL, drops or refreshes the first-party cookie, and is safe to call multiple times.

op.track();

Identify

Call when a user signs up or logs in. This is what stitches an authenticated user to the click that brought them in — enabling cross-device attribution and ITP-resilience on Safari.

op.identify(user.id, {
  email: user.email,
  // any traits you want to expose to the partner dashboard
});

You can call identify() multiple times — the same user always maps to the same Identity row, and additional traits are merged.

Anonymous tracking

If you don’t want to expose userIds, you can identify with a hash:

op.identify(sha256(user.email + SITE_SALT));

The attribution chain still works because the same hash is reproducible across sessions.
