Real-Time Inventory Sync for HubSpot CMS
A luxury retail brand wanted to use HubSpot CMS for its high-end aesthetic but needed real-time inventory levels to prevent overselling. Their inventory lived in a custom-built SQL database with no native HubSpot connector.
The Challenge
- High Traffic: The site needed to handle flash sales with thousands of concurrent users.
- Low Latency: Inventory checks needed to happen in milliseconds to ensure a smooth UX.
- Data Integrity: Stock levels had to be 100% accurate across the website and the physical warehouse.
The Solution
We implemented a hybrid architecture combining HubSpot CMS with a custom middleware layer.
- Serverless API: We built a high-speed API on AWS Lambda that proxies requests to the SQL database.
- Custom Modules: Developed HubSpot CMS modules that use client-side fetching to show "Live Stock" badges.
- Webhooks: Implemented a bidirectional sync where sales on the site immediately reserve stock in the backend.
The Result
- Sub-100ms Response Times: Inventory data loads almost instantly.
- Zero Overselling: Stock levels are perfectly synced across all channels.
- Marketing Control: The marketing team can now launch campaigns knowing the technical infrastructure will scale.
