Frequently asked questions
Do we need to change our existing systems?
No. Paynion runs on top of your existing systems through web services and APIs.
What is the difference between an HHS and a YÖS?
The HHS holds the customer's account and exposes the APIs; the YÖS is the authorised provider that uses those APIs to offer account information or payment initiation to the customer.
