Why teams connect Close and MongoDB
Treat Close 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 Users, Smart Views, Leads, Contacts from Close into Collections, Documents, Embedded documents and arrays, Indexes in MongoDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Close 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
- Keep Close contacts aligned with a marketing automation platform so outreach lists stay current.
- Push call, SMS, and email activity data into a warehouse for rep performance and outreach-cadence analysis.
- Keep a MongoDB-backed product catalog aligned with an ERP's item master in both directions.
- Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
Query the CRM like a database
Accounts, contacts, and custom objects from Close 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 Close, 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 Close API, limits, and retries.
What you can sync between Close 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.
| Close objects | MongoDB objects | |
|---|---|---|
| Tasks Follow-up items assigned to users; synced for workload and SLA reporting. | Documents BSON records created, updated, and deleted during syncs, keyed by _id. | |
| Custom Activities User-defined activity types with their own custom fields, mapped like standard activities. | Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. | |
| Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs. | Indexes Keep lookups by sync key fast on large collections. | |
| Users Sales reps referenced as owners on leads, opportunities, and activities. | Views Read-only aggregation-defined sources for filtered sync datasets. | |
| Smart Views Saved lead searches that can scope which records a segment-based sync pulls. | Change streams The oplog-backed event feed that powers real-time change capture. | |
| Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history. | GridFS files Chunked file storage whose metadata can be referenced by synced documents. |

How the Close and MongoDB connectors work
Close
- Integration surface
- REST API
- Authentication
- API key (sent via HTTP Basic auth)
- Change detection
- Webhook subscriptions for record events, with polling on date_updated fields for backfills
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to per-endpoint rate limits communicated in response headers
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

FAQ
Close and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Close and MongoDB: authenticate both systems, choose the objects to sync (such as Close's Tasks and Custom Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Close and MongoDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Close–MongoDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Close and MongoDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Close: Webhook subscriptions for record events, with polling on date_updated fields for backfills. On MongoDB: 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. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Close side: Users, Smart Views, Leads, Contacts, plus custom fields where Close exposes them. On the MongoDB side: Collections, Documents, Embedded documents and arrays, Indexes. Stacksync auto-detects both schemas and converts types between the two systems.
-
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.
