Why teams connect HubSpot and MySQL

Treat HubSpot like part of your database: its records live in MySQL 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 MySQL, where it can be queried and joined like everything else.

Stacksync mirrors Pipeline, Stages, Audit, Contact from HubSpot into Tables, Views, Columns, Primary and Unique Keys in MySQL 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.
  • Replicate ERP master data (customers, items, pricing) into the MySQL databases behind storefronts and portals
  • Keep e-commerce orders in MySQL flowing into finance and fulfillment systems without export scripts

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to MySQL sync onto the matching records in HubSpot, giving go-to-market teams live product context.

Internal tools without API code

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

What you can sync between HubSpot and MySQL

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.

HubSpot objects MySQL objects
Product Synced with incremental and full sync per the Stacksync docs. Stored Procedures Server-side logic that can post-process synced rows.
Ticket Synced with incremental and full sync per the Stacksync docs. Triggers An alternative change-capture mechanism when binlog access is unavailable.
Quote Synced with incremental and full sync per the Stacksync docs. Databases (Schemas) Top-level namespaces that scope a sync's reads and writes.
Goal Synced with incremental and full sync per the Stacksync docs. Tables The primary sync target; rows map to records in connected systems.
Owner Synced with incremental and full sync per the Stacksync docs. Views Read-side projections used as outbound sync sources.
Pipeline Synced with incremental and full sync per the Stacksync docs. Columns Field-level mapping targets with engine-typed values.

How the HubSpot and MySQL 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
Change detection
Records: incremental near-real-time change tracking. Associations: HubSpot has no native association CDC
Capabilities
read · write · CDC · webhooks
Rate limits
Request limits vary by subscription tier and API type.
HubSpot setup guide

MySQL

Integration surface
SQL wire protocol (MySQL client/server protocol)
Authentication
Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
Change detection
Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits and server resources
