Shopify Webhook Retries & ERPNext Integration Idempotency (Why Duplicates Break Data)

Shopify retries webhooks. Background queues retry jobs. Networks fail. All of this is normal behavior. If an integration between ERPNext and Shopify cannot safely process the same event more than once, it is not production-ready. This is where idempotency becomes critical. Idempotency means that processing the same event multiple times must always produce the same result - without duplicating data, corrupting records, or breaking stock and accounting. In this video, I explain: 🔁 Why Shopify webhooks are retried 📦 How duplicate events silently corrupt ERPNext data 🧠 What idempotency really means in ERP integrations 🏗️ Why “create-only” logic fails in production ⚠️ How non-idempotent integrations break under real traffic This video is part of a deep technical series on building production-grade ERPNext Shopify integrations, based on real-world system behavior - not ideal conditions.
