The Boleto API supports the full boleto lifecycle, enabling clients to create, retrieve, extend, and cancel boletos via secure integration. It also supports Bolepix, which adds a Pix QR code to the boleto for instant settlement through Pix rails. For boletos paid via barcode or digitable line, the API provides an early payment notice before final settlement - offering visibility of the payment up to one day in advance, with guaranteed settlement. For boletos paid via Pix (via Bolepix), the boleto is marked as paid directly, as settlement is immediate.
