  title: Nuvei Direct Merchant Notifications (DMN)
  version: "1.0"
  description: |
    Asynchronous webhook notifications delivered from Nuvei to a merchant-configured notificationUrl
    when payments, payouts, refunds, voids, settles, or Control Panel events reach their final state.
    Payment DMNs include an `advanceResponseChecksum` (SHA-256 over the merchantSecretKey followed
    by an ordered concatenation of payload values). Withdrawal DMNs sign `name=value` pairs with the
    secret appended.
