The primary goal was to develop a bespoke payment solution for Ukrainian railway ticket sales via multiple secure interfaces made available by certain Ukrainian banks and third-party partners. To achieve this, First Bridge developed several APIs to connect six local banks and certain third party partners with the Ukrainian Railway interface in order to enable ticket sales via their own interfaces.

The development of these APIs required a modification of the participating banks' protocols to enable order tracking, refunds (including partial refunds), and commission sharing through the creation of specific IDs and a bespoke routing technology. The resulting efficiency translates to lower fees for the railways and their customers as commissions could be more efficiently attributed between system participants. Finally, a tailor-made antifraud module was implemented to minimise the risk of ticket fraud.
