MySQL Connector for Marketing Automation
The challenge:
A German food-tech company had built a sophisticated ordering platform with rich customer data — user preferences, order history, branch associations, NPS reviews, and wallet transactions — all stored in a MySQL database.
Their marketing and customer success teams used HubSpot but had zero visibility into this data.
Every campaign required manual exports, and customer support couldn't see order history without switching systems.
What we built:
A custom real-time sync pipeline connecting their MySQL database directly to HubSpot.
Using Cloudflare Workers and Hyperdrive, we built a scheduled sync that runs every 10 minutes, pulling fresh data from 12 database tables and upserting it into HubSpot objects — including custom objects for orders, branches, dishes, menus, NPS reviews, and wallet logs.
The sync uses incremental updates based on timestamps stored in a KV database, so each run only fetches records that changed since the last sync. This keeps API calls minimal and performance fast, even with tens of thousands of records.
Key results:
12 database tables synced to HubSpot in near real-time
Associations handled automatically via HubSpot workflows
Customer support now sees full order history directly in contact records
Marketing can segment users by preferences, allergens, order frequency, and NPS scores
Infrastructure cost: under $25/month on Cloudflare's edge network
The same architecture can be applied to any MySQL, PostgreSQL, or cloud database that needs continuous sync with a CRM or marketing platform.
