Juspay Context

Where the payment orchestration work sits

A simplified view of Juspay's role in a transaction path: orchestration branches into authentication and authorization work, while production ownership keeps those flows explainable.

What Juspay is doing in this story

Juspay sits in the payment infrastructure layer between merchant checkout, authentication services, gateways, and banks. Yogesh's work maps to the backend orchestration around this surface: API contracts, UAS/3DS authentication, gateway routing, risk systems, analytics, and production readiness.
