SDNBros auto-detects these Shopify events:

Common Errors & How to Fix Them

Error	Cause	Fix
HTTP 401	X-Shopify-Hmac-Sha256 verification failing	Check your Shopify API secret matches the signing secret in SDNBros
Missing events	Shopify only sends webhooks for events you've subscribed to	Add more webhook subscriptions in Shopify Admin → Notifications
Delayed delivery	Shopify queues webhooks during high-traffic periods	This is normal during sales events. SDNBros shows exact delivery timing.

Why Use SDNBros for Shopify Webhooks?

• Auto-classification: We detect Shopify webhooks by signature headers — zero configuration
• Root-cause diagnosis: When a delivery fails, we tell you exactly why (timeout, auth error, server crash) with Shopify-specific context
• Replay safety: Know if it's safe to replay a failed event before you click the button
• Operational visibility: Public service and network status telemetry
• CLI tunnel: sdnbros webhook tunnel --port 3000 forwards webhooks to localhost
