Study the solution

Server Actions are RPC-like functions co-located with components, ideal for form mutations and progressive enhancement. Route Handlers (route.js) are explicit REST/HTTP endpoints for webhooks, third-party clients, or public APIs. Use Actions for your own UI mutations, Handlers for external/HTTP needs.

Read the code

Same intent, two mechanisms
// Server Action — internal UI mutation
'use server';
export async function subscribe(formData: FormData) { /* ... */ }

// Route Handler — external webhook (Stripe)
// app/api/webhooks/stripe/route.ts
export async function POST(req: Request) {
  const event = verifyStripe(await req.text(), req.headers);
  // ... handle event
  return Response.json({ received: true });
}
