System Design: Building a Bulletproof Payment Gateway! 🚀 Basic payment setups fail during network timeouts. To block catastrophic duplicate charges, enforce client-generated idempotency keys (UUIDs). The server saves this key first; if a duplicate request arrives, it immediately returns the cached result instead of re-charging the buyer. Never overwrite database rows to update payment statuses. Instead, implement an immutable ledger where every state change—authorized, captured, or refunded—creates a brand-new row. Securely ingest asynchronous updates using signed webhooks, validating event IDs before appending them to the timeline. This design writes intents to the ledger before calling the API, shields endpoints with idempotency keys, and uses webhooks to build a flawless, fully auditable financial history. #SystemDesign #SoftwareArchitecture #PaymentGateway #Stripe #BackendDevelopment #Microservices #FinTech #Database #Idempotency #Webhooks #TechTips #codingforkids
