How the bill payment flow works
Every step is managed by the SDK. Your application calls SDK methods and receives results — the device interactions happen inside the platform layer.
Biller selection
Customer selects from a biller list or searches by name. SDK manages the biller catalogue feed and session state.
Account reference entry
Customer enters the account or reference number. SDK validates the format before fetching the bill.
Bill fetch
SDK calls the biller API with the reference number. Returns the outstanding amount and due date to the application.
Payment
Customer pays via card (PCI terminal), cash (bill acceptor), or wallet. SDK handles the payment device and posts to the biller or clearinghouse.
Confirmation and receipt
SDK posts the payment, receives confirmation, triggers the receipt printer, and closes the session.
