Tracking Multi-Domain Affiliate Referrals on Modern Web Architectures

The Multi-Domain Attribution Challenge

When a B2B SaaS company operates a marketing site on one domain (e.g., `brand.com`) and an application checkout on another (e.g., `app.brand.com`), basic tracking cookies often drop between domains, leading to lost attribution.

Cross-Domain Attribution Architecture

Maintaining accurate tracking requires cross-domain parameter forwarding and session persistence that matches referral tokens directly to the Stripe checkout session ID upon customer registration.
