How to architect webhook receivers that survive third-party outages, enforce cryptographic signature verification, and process idempotent ERP notifications reliably.
When connecting CS-Cart to external warehouse management, ERPs, or payment gateways, network timeouts and duplicate delivery are inevitable.
This article shares our blueprint for queue-backed webhook ingestion, HMAC signature verification, database transaction isolation, and idempotency key checking to guarantee zero duplicate order processing.
Always isolate customizations in dedicated modular add-ons rather than modifying core CS-Cart controller or template files. This preserves upgrade integrity, enables safe rollbacks, and prevents database concurrency issues during high-volume periods.
