Stop Double Charging Customers

𝐒𝐭𝐨𝐩 𝐝𝐨𝐮𝐛𝐥𝐞 𝐜𝐡𝐚𝐫𝐠𝐢𝐧𝐠 𝐜𝐮𝐬𝐭𝐨𝐦𝐞𝐫𝐬 when network glitches hit your payment flow. Stripe retries failed webhooks automatically, but without proper safeguards, a single purchase can trigger duplicate fulfillments and messy account states. 💳

Building a resilient integration requires three core defenses: • Lock incoming Stripe event IDs atomically in Redis or SQL to guarantee idempotency • Acknowledge payloads fast and offload business logic to background message queues • Route unhandled failures into a dead letter queue for safe replay and reconciliation 🛠️

Protect your revenue and keep data clean before edge cases hit production. 🚀
