Why teams connect MongoDB and Nutshell
Treat Nutshell 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 People, Companies, Activities, Tasks from Nutshell into Databases, Collections, Documents, Embedded documents and arrays in MongoDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Nutshell 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
- Mirror tasks and activities into ops tools for cross-team visibility.
- Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
- Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
- Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
Query the CRM like a database
Accounts, contacts, and custom objects from Nutshell 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 Nutshell, 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 Nutshell API, limits, and retries.
What you can sync between MongoDB and Nutshell
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.
| MongoDB objects | Nutshell objects | |
|---|---|---|
| Change streams The oplog-backed event feed that powers real-time change capture. | Activities Logged calls, meetings, and emails used for engagement reporting | |
| GridFS files Chunked file storage whose metadata can be referenced by synced documents. | Tasks Rep to-dos mirrored into external work-management or reporting systems | |
| Databases Logical groupings of collections that scope a sync connection. | Notes Free-text history attached to leads and contacts, replicated for a full timeline | |
| Collections The table-like sync unit; each collection maps to a table or object in the paired system. | Products Line items attached to leads, used to sync sold products into billing | |
| Documents BSON records created, updated, and deleted during syncs, keyed by _id. | Tags Segmentation labels mapped to lists or filters in downstream tools | |
| Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. | Users Rep records used to resolve ownership when syncing assignments |

How the MongoDB and Nutshell connectors work
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
- Capabilities
- read · write · CDC
Nutshell
- Integration surface
- JSON-RPC API over HTTPS; a newer REST API is also offered

FAQ
MongoDB and Nutshell integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between MongoDB and Nutshell: authenticate both systems, choose the objects to sync (such as MongoDB's Change streams and GridFS files), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for MongoDB and Nutshell: Query the CRM like a database; Product events onto CRM records; Internal tools without API code. Accounts, contacts, and custom objects from Nutshell become tables in MongoDB you can join with application data directly.

MongoDB: 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. Nutshell: JSON-RPC API over HTTPS; a newer REST API is also offered. Authentication: HTTP Basic with account email and API key. Stacksync manages authentication, retries, and rate limits on both sides.
-
Nutshell: The deal object is called a Lead in Nutshell, and it links to separate People and Company records rather than replacing them. MongoDB: Documents are schemaless BSON with a 16 MB size limit, so field mappings must tolerate documents that differ in shape within one collection. Stacksync's field mapping accounts for these differences between MongoDB and Nutshell without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means MongoDB and Nutshell records are not retained after a sync operation.
