Supporting Services
This section covers services that do not directly initiate payment but support payment flows. Supporting services aim to ensure correct decisions during integration, improve the user experience, and provide operational controls.
This document Supporting Services provides a general framework for the main page. Detailed technical information for each service is available on the relevant subpages.
