Developers debate Pix webhook reliability in production systems
Original: Todo sistema que recebe Pix depende de uma notificação assíncrona do PSP: o webhook. Em produção,... # java # fintech #
Brazilian developers are discussing how payment systems handle Pix notifications, focusing on the webhook that payment providers send asynchronously when money arrives. The debate centres on how to guarantee a Pix is credited exactly once in production, touching on distributed systems design, idempotency and testing practices for fintech infrastructure built in Java.
Why now: Pix is central to Brazilian payments, so engineering challenges around reliable webhook processing attract attention from the fintech and developer community.
