Flutterwave Quote Fee Then Charge

  title: Flutterwave Quote Fee Then Charge
  summary: Retrieve the processing fee for an amount, create the customer, then charge and verify it.
  description: >-
    A transparency-first collection flow. The workflow retrieves Flutterwave's
    fee calculation for an amount, currency, and payment method so the merchant
    can show the true cost, creates the customer that will own the charge,
    initiates the charge, and retrieves the charge to confirm its final status.
    The verify step branches on whether the charge succeeded or failed. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
