How HelpPay uses BPAY

The HelpPay app only requires 4 pieces of information to upload a bill; the BPAY biller code, the customer reference number, the due date, and the amount due. Once a bill has been uploaded, our users can freely share their bills with anyone. Each bill upload generates a public payment page that is easily shared with a unique link and allows anyone, with or without the HelpPay app, to contribute to the customer's bill.

By using BPAY's APIs, we can validate that the bill is from a legitimate provider and ensure that the contributions made towards a bill, will go directly to the company that issued that bill.
