 Catatan penting:
 
 - Route backend memakai global prefix `/api`, jadi endpoint controller `GET /webhooks/whatsapp` menjadi `GET /api/webhooks/whatsapp`.
+- Di production, `nginx` mengekspos backend internal aplikasi lewat prefix `https://portal.bizone.id/backend-api`.
+- Prefix `/api/*` di browser dipakai oleh route handler Next.js untuk operasi dashboard seperti save contact, save user, export, dan aksi client-side lain.
 - Jika Anda ingin verifikasi tanda tangan resmi dari Meta, isi `META_WEBHOOK_APP_SECRET`.
 - Bila `META_WEBHOOK_APP_SECRET` terisi, request ke `POST /api/webhooks/whatsapp/meta` menuntut header `x-hub-signature-256`.
 - Endpoint `POST /api/webhooks/whatsapp` tetap bisa dipakai untuk Meta bila Anda memilih verify token + shared secret non-Meta untuk test lain, tetapi untuk produksi Meta lebih aman menargetkan URL default callback dan menyimpan `META_WEBHOOK_APP_SECRET`.
