Beyond Shopify's Default Retries: Building Webhooks for Real Outages

Shopify's automatic retry mechanism—8 attempts over 4 hours with exponential backoff—handles brief disruptions well but fails during genuine outages like long deployments, API rate limits, or traffic spikes. Many developers unknowingly face silent data loss when their systems remain down longer than 4 hours, as failed webhooks are permanently discarded without notification. Understanding Shopify's retry limitations and implementing a robust custom retry layer is essential to preventing data inconsistencies and maintaining customer trust.
