Affiliate management for SaaS and crypto businesses

Works with any backend language

// 1. Capture affiliate code on any frontend
const ref = new URLSearchParams(window.location.search).get('ref');
if (ref) localStorage.setItem('affiliate_ref', ref);

// 2. Save ref to user record at signup
// user.affiliate_ref = localStorage.getItem('affiliate_ref')

// 3. Report sale when purchase is completed (Node.js example)
const payload = {
  event:       'sale.completed',
  referred_by:  user.affiliate_ref,
  sale_amount:  order.total,
  sale_id:      order.id
};
const sig = crypto.createHmac('sha256', YOUR_SECRET)
  .update(JSON.stringify(payload)).digest('hex');

await fetch('https://wereffer-api-production.up.railway.app/webhook/your-slug', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'x-wereffer-signature': sig },
  body: JSON.stringify(payload)
});
