Why teams connect HubSpot and SQL Server

Treat HubSpot like part of your database: its records live in SQL Server as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in SQL Server, where it can be queried and joined like everything else.

Stacksync mirrors Line Item, Product, Ticket, Quote from HubSpot into Primary and Unique Keys, CDC Change Tables, Stored Procedures, Databases in SQL Server with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in HubSpot with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • Consolidate branch or plant databases into a single operational SQL Server hub
  • Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the HubSpot API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in HubSpot arrive as row changes in SQL Server, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from HubSpot become tables in SQL Server you can join with application data directly.

What you can sync between HubSpot and SQL Server

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

How the HubSpot and SQL Server connectors work

HubSpot

Integration surface
REST API (CRM v3)
Authentication
OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields

Rate limits
Request limits vary by subscription tier and API type.
HubSpot setup guide

SQL Server

Integration surface
SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
Authentication
Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
Change detection
SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
Capabilities
