  title: Efí Bill Payment by Bar Code
  summary: Decode a boleto bar code, pay it from the account, and reconcile the status.
  description: >-
    The Efí Pay Pagamentos flow for paying a boleto or concessionária bill from
    the account balance. The workflow authenticates, decodes the bar code (linha
    digitável) to recover the amount and due date, submits the payment request
    for that bar code, and reads the resulting payment back by its id to
    reconcile the settlement status. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
