Automate QR-based PIX and C2C payments by decoding the QR code text or image to automatically route, parse, and confirm transactions through a unified API client. The workflow detects the QR type, enforces PIX amount rules, and polls for the final payment status.

QR type detection works by parsing the decoded QR code data to identify whether it is a PIX or C2C payment, then routing the request to the proper API endpoints. This mechanism ensures the correct validation rules and amount flows are applied for each transaction type.

You can process both preset-amount and changeable-amount QR codes. The workflow parses the QR data, allows you to set the amount if the flow permits, and enforces specific PIX amount rules before confirming the payment.

Prevent duplicate QR payments by using local state persistence and explicit user confirmation before finalizing any transaction. The workflow guards against duplicate payments by managing state across the decode, parse, and confirm stages of the process.

Recover interrupted PIX or C2C payments through the workflow's local state management and robust error handling. The system persists the payment state during the decode and confirm stages, allowing you to resume or safely retry without duplicating the transaction.

You need an OpenAPI-driven transport to manage the QR payment workflow, including status polling. It provides the structured communication layer required to drive decode, parse, confirm, and status polling operations while maintaining local state.
