Why teams connect HubSpot and MongoDB

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

Stacksync mirrors Pipeline, Stages, Audit, Contact from HubSpot into GridFS files, Databases, Collections, Documents in MongoDB 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 operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
  • Capture change stream events and propagate them to SaaS tools in near real time instead of running batch exports.

Trigger workflows from CRM changes

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

Query the CRM like a database

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

Product events onto CRM records

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

What you can sync between HubSpot and MongoDB

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 MongoDB objects
Ticket Synced with incremental and full sync per the Stacksync docs. Databases Logical groupings of collections that scope a sync connection.
Quote Synced with incremental and full sync per the Stacksync docs. Collections The table-like sync unit; each collection maps to a table or object in the paired system.
Goal Synced with incremental and full sync per the Stacksync docs. Documents BSON records created, updated, and deleted during syncs, keyed by _id.
Owner Synced with incremental and full sync per the Stacksync docs. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets.
Pipeline Synced with incremental and full sync per the Stacksync docs. Indexes Keep lookups by sync key fast on large collections.
Stages Synced with incremental and full sync per the Stacksync docs. Views Read-only aggregation-defined sources for filtered sync datasets.

How the HubSpot and MongoDB 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

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
