Why teams connect Attio and MongoDB
Treat Attio 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 Companies, Users, Deals, Workspaces from Attio into Embedded documents and arrays, Indexes, Views, Change streams in MongoDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Attio 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
- Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
- Write product usage and enrichment data into Attio attributes so GTM teams work from live account signals.
- 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.
- Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
Product events onto CRM records
Signup, usage, or lifecycle changes written to MongoDB sync onto the matching records in Attio, 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 Attio API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Attio arrive as row changes in MongoDB, ready to drive jobs and notifications.
What you can sync between Attio 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.
| Attio objects | MongoDB objects | |
|---|---|---|
| People Standard person object; synced with marketing tools and warehouse person tables. | Indexes Keep lookups by sync key fast on large collections. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Views Read-only aggregation-defined sources for filtered sync datasets. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Change streams The oplog-backed event feed that powers real-time change capture. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | GridFS files Chunked file storage whose metadata can be referenced by synced documents. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Databases Logical groupings of collections that scope a sync connection. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Collections The table-like sync unit; each collection maps to a table or object in the paired system. |

How the Attio and MongoDB connectors work
Attio
- Integration surface
- REST API
- Authentication
- Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key)
- Change detection
- Webhooks on record and list-entry events, with polling as a fallback
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to the platform's published API rate limits.
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
How it works
How to connect Attio to MongoDB — three steps, no code

FAQ
Attio and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and MongoDB: authenticate both systems, choose the objects to sync (such as Attio's People and Companies), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Attio: The data model is user-definable: standard objects like people and companies coexist with custom objects, and attributes can be added to any object, so syncs read the schema at runtime. MongoDB: Replica set configuration is required even for a single node — standalone MongoDB cannot be change-tracked. Stacksync's field mapping accounts for these differences between Attio and MongoDB 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 Attio and MongoDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Attio and MongoDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Attio–MongoDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Attio and MongoDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. 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.
