Konsep: Payment Flow

Payment flow end-to-end:

1. User memilih plan/produk di app
2. Checkout — user isi detail pembayaran
3. Payment Gateway (Midtrans/Xendit) proses transaksi
4. Webhook — gateway kirim konfirmasi ke server kamu
5. Server update status → user dapat akses

Webhook signature verification itu WAJIB. Tanpa itu, siapapun bisa fake webhook dan “bayar” gratis.
