ThriveCart success-page router

Internal. Routes post-purchase traffic to the right welcome page based on whether the upsell was taken. ThriveCart allows only one success page per funnel, so this sits between the cart and the thank-you pages.

Endpoints

/r — the router. This is the URL that goes in ThriveCart.
/r/debug — dumps the full query string as JSON instead of redirecting. Point ThriveCart here for one test order to confirm the payload, then switch to /r.

Set these in Vercel → Settings → Environment Variables, then redeploy. Any unset destination renders a plain thank-you page naming the missing variable rather than breaking the redirect.

ThriveCart setup

Two settings, both required. Product → Fulfillment→ “Send them to a URL” → the /r URL. Then checkout editor → Success Page → Edit → “Automatically redirect to Success URL”. Without the second, customers land on the ThriveCart-hosted page with a link instead of redirecting.
