A well-designed TX Gateway is not just a reverse proxy – it is the in a distributed system. It must be built with state persistence, idempotency, retry management, and observability as first-class concerns. When implemented correctly, it enables reliable, secure, and auditable transaction processing at scale, while shielding clients from backend complexity and failures.
A TX Gateway (Transaction Gateway) is a critical component in payment processing systems, enabling secure and efficient transactions between merchants, customers, and financial institutions. This guide provides an overview of the TX Gateway, its functions, architecture, and best practices for implementation.
