Partnersify Tracking on Remix

Remix's root.tsx is the right place for the pixel, and action functions or resource routes handle passing the affiliate cookie to Stripe.

Step 1: Add the pixel

Add the pixel in root.tsx inside the <head> of your document:

// app/root.tsx
import { Links, Meta, Scripts } from '@remix-run/react';

export default function App() {
  return (
    <html>
      <head>
        <Meta />
        <Links />
        <script
          dangerouslySetInnerHTML={{
            __html: `window.partnersify = window.partnersify || function() { (window.partnersify.q = window.partnersify.q || []).push(arguments); };`,
          }}
        />
        <script
          async
          src="https://partnersify.com/partner.js"
          data-partnersify="YOUR_MERCHANT_ID"
        />
      </head>
      <body>
        {/* ... */}
        <Scripts />
      </body>
    </html>
  );
}

Replace YOUR_MERCHANT_ID with the ID from Setup → Install tracking.

In a Remix action or resource route, parse the Cookie header and forward it to your Stripe Checkout Session:

// app/routes/checkout.tsx (or a resource route)
import { redirect } from '@remix-run/node';
import type { ActionFunctionArgs } from '@remix-run/node';
import Stripe from 'stripe';

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);

export async function action({ request }: ActionFunctionArgs) {
  const cookieHeader = request.headers.get('Cookie') ?? '';
  const partner = parseCookie(cookieHeader, 'psfy_partner');

  const session = await stripe.checkout.sessions.create({
    // ... your line items, success_url, etc.
    metadata: {
      psfy_partner: partner ?? null,
    },
  });

  return redirect(session.url!);
}

function parseCookie(header: string, name: string): string | null {
  const match = header.match(new RegExp(`(?:^|;\\s*)${name}=([^;]*)`));
  return match ? decodeURIComponent(match[1]!) : null;
}

If you prefer, install the cookie npm package for parsing. The pattern above works without dependencies.
