3-Step Payment Orchestration

Modular payment framework enabling independent Authentication, Authorization, and Capture workflows.

Supports delayed capture & independent workflow stages

[01]SYSTEM OVERVIEW

Core payment orchestration framework enabling Authentication, Authorization, and Capture to function as independent, extensible workflows across Juspay's payment stack.

The Engineering Challenge

Legacy monolithic authorization flows tightly coupled authentication, authorization, and capture stages, preventing delayed capture support and limiting merchant payment lifecycle flexibility.

Implemented Solution

Designed a modular 3-step orchestration framework where each stage operates independently with its own state machine, enabling flexible sequencing, delayed capture, and merchant-configurable lifecycles.

[02]SYSTEM ARCHITECTURE

Independent state machines per stage (Auth, AuthZ, Capture) with defined transition contracts
Event-driven coordination via Kafka for cross-stage communication without tight coupling
PostgreSQL for durable state persistence with optimistic locking for concurrent stage transitions
Pre-auth revamp: simplified multi-stage authorization with extensible feature hooks per service

[04]KEY FINDINGS & TAKEAWAYS

Explicit state machine design surfaces edge cases that implicit flow-control through conditionals hides

Decoupling capture from authorization immediately unblocks a wide category of merchant integration patterns
