How to redirect after Stripe payment to a gated dashboard with Webflow Cloud

Webflow Cloud can be used to add a server-backed, Stripe-gated dashboard to a Webflow marketing site by mounting a Next.js 15 App Router application under a path such as `/app`, while keeping marketing pages and the Buy button in Webflow Designer. The approach creates a Stripe Checkout Session through a server Route Handler, redirects successful purchasers to a return route that retrieves and verifies the paid Stripe session, then issues an HTTP-only, signed, time-limited cookie containing customer claims. Root-level `middleware.ts`, which must remain Edge-compatible for Webflow Cloud’s Cloudflare Workers environment, verifies that cookie before allowing dashboard access, while the dashboard page repeats the validation as a fail-safe. Required setup includes Stripe keys and Price IDs, a secure cookie-signing secret, npm and supported Node.js versions, and a correctly configured application base path; sensitive values should be stored as Webflow Cloud secrets. The guidance warns against Next.js 16’s `proxy.ts` for this use case, unsupported `runtime = 'edge'` directives, incorrect mount paths, insecure or mis-scoped cookies, and inconsistent signing secrets, while recommending rate limits and stronger buyer identity, redemption, and webhook-based controls for higher-value production access.
