Payment FlowAI Workflow

“Run `npx radzor@latest add stripe-checkout webhook-receiver email-send` to install 3 Radzor components. Then read components/radzor/stripe-checkout/radzor.manifest.json, components/radzor/webhook-receiver/radzor.manifest.json, components/radzor/email-send/radzor.manifest.json and each component's llm/integration.md. Wire them together to full Stripe checkout with email confirmation: creates the payment session, listens to the webhook, and automatically sends a receipt. Use the manifest's inputs (check envVar for required environment variables), outputs (check fields for object shapes), composability (check mapField for field extraction), and actions — don't invent custom interfaces.”

// Create checkout session and redirect
const session = await checkout.createCheckout("customer@example.com")
// redirect user to session.url
