In this video, we’ll explore why payment retries are crucial for any backend system handling financial transactions. You’ll learn how to design a fault-tolerant payment workflow, track payment statuses using an append-only database, and implement a robust retry strategy with features like exponential backoff and idempotency.

Key Topics:
• Understanding common payment statuses (Initiated, Processing, Succeeded, Failed, Pending Retry, Refunded, Cancelled)
• How an append-only table helps preserve a complete transaction history
• Best practices for retry logic to avoid duplicate charges and reduce downtime
• Logging and monitoring tips for seamless troubleshooting

If you’re looking to build more resilient financial systems, or simply want to level up your backend engineering skills, this video is for you!
