  title: Efí Pix Due Charge to QR Code
  summary: Create a Pix due charge with a due date, confirm it, and render its QR Code.
  description: >-
    The Pix "cobv" (cobrança com vencimento) flow used for boleto-style Pix
    charges that carry a due date, fines, and interest. The workflow
    authenticates, creates a due charge under a caller-supplied txid, reads it
    back to confirm registration and resolve its location id, and generates the
    QR Code payload the payer scans. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
