The flow of payment request is described in the following diagram. The dotted paths between Merchant and NumeroPay are optional as some payment requests can be sent over links using emails, SMS or QR code scans. In such cases the User initiates and ends the journey with NumeroPay. In case of web or app integration, the payment transaction is initiated from Merchant (website or app) and after completion, returns to Merchant for their system’s processing.

The dotted path between Bank and NumeroPay is a server sided secure request initiated from Bank to update payment request to NumeroPay.
