Circuit–Subbly Webhook Integration Service
A production Node.js webhook service that syncs delivery events from Circuit to Subbly order status in real time.

- Logistics / Subscription Commerce
The challenge
Delivery completion in Circuit wasn't automatically reflected in Subbly. That meant manual status updates, delayed customer notifications, and inconsistent tracking for high-volume subscription deliveries.
The solution
Built a webhook integration service that listens to Circuit events and updates Subbly orders to 'shipped', supporting multi-order deliveries and sending accurate customer notifications. Implemented Cloudflare bypass headers, robust logging, health checks, and error handling.
Key highlights
- Real-time Circuit webhook ingestion and mapping to Subbly orders.
- Multi-order handling with comma-separated IDs for bundled deliveries.
- Cloudflare bypass via browser-like headers for reliable Subbly API calls.
- Structured Winston logging for production debugging and monitoring.
- Health check endpoints for uptime and status dashboards.
