  title: Flutterwave Wallet Balance Guarded Payout
  summary: Check a currency wallet balance, then only send a transfer to an existing recipient when funds are sufficient.
  description: >-
    A funds-guarded disbursement flow. The workflow fetches the available
    balance for a currency wallet and branches: when the available balance is
    high enough it initiates a transfer to an existing recipient and verifies
    the payout status, and when it is not it ends without moving money. This
    prevents failed payouts caused by an underfunded wallet. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
