We integrated Tpay with Sylius to provide merchants with reliable and widely trusted payment processing. The solution supports various payment methods, secure callbacks, and seamless synchronization of order and payment statuses — all in clean, maintainable code. Merchants benefit from faster checkout completion, fewer failed transactions, and simpler accounting. In this article, we describe webhook handling, error recovery mechanisms, and the testing strategy that made the integration rock-solid.

We created a dedicated ticketing platform based on Sylius that revolutionized ticket sales and management for the country's largest PHP conference. The system offers intuitive ticket and seat management, secure payments, automatic invoicing, and integrations with CRM and mailing tools. It was designed to handle peak loads, relieves organizers from manual tasks, and improves attendee experience - in this article we show key architectural choices, major implementation stages, and the results achieved.
