Sylius
Sylius is a modern open-source e-commerce framework based on Symfony, providing scalable and customisable online shops for developer teams.
Brief Profile
Overview
By integrating Payrexx via Payum Gateway, Sylius can process payments from Switzerland (e.g., TWINT, credit cards, QR invoices) directly in the checkout process – secure, flexible, and automatable.
System & Origin: Open-source (MIT license) e-commerce framework, developed in Poland since 2011; used by over 7,000 stores.
Architecture: Modular, API-based, and headless capable – ideal for bespoke frontends, B2B use cases, and omnichannel scenarios.
Product
Checkout & Payment: Integrates payment modules via the Payum library system, supports capturing, refunds, and state-machine-based processing.
Payrexx Gateway Addon: Example projects demonstrate that Payrexx can be integrated using the Payum plugin – including support for TWINT and Swiss payment options.
Applications
For Developers & Agencies: Ideal for bespoke shop solutions, e.g., B2B portals, multi-channel shops, or API-first implementations.
Payrexx Payments: Payments are initiated via the Payrexx API and synchronized via webhooks – the entire checkout remains embedded in Sylius. Support for national and international payment methods ensures a seamless UX.
