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.

Syncing Attio to MongoDB gives product and engineering teams an operational mirror of CRM data in the database their applications already use. Attio People, Companies, and Deals replicate into MongoDB Collections as Documents, and writes to those Documents flow back into Attio.

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

  • 01 Show CRM-driven account context inside your product by reading from MongoDB instead of the Attio API
  • 02 Let backend services update Attio Deals by writing Documents to a Collection
  • 03 Model Attio Custom objects as embedded documents for flexible schemas
  • 04 Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.

Common sync patterns

CRM data as Documents

Attio People, Companies, and Deals sync into MongoDB Collections, including nested data as embedded documents and arrays

Reverse sync from the app

Document updates written by your application propagate back to Attio records and Custom objects

Query-optimized mirror

Indexes and Views over synced Collections serve CRM data to product features at application speed

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 How this pairing syncs
People Standard person object; synced with marketing tools and warehouse person tables. Indexes Keep lookups by sync key fast on large collections. People is specific to Attio and Indexes to MongoDB — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. Views Read-only aggregation-defined sources for filtered sync datasets. Companies is specific to Attio and Views to MongoDB — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. Change streams The oplog-backed event feed that powers real-time change capture. Users is specific to Attio and Change streams to MongoDB — each maps to any object or custom field on the other side.
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. Deals is specific to Attio and GridFS files to MongoDB — each maps to any object or custom field on the other side.
Workspaces Synced with incremental and full sync per the Stacksync docs. Databases Logical groupings of collections that scope a sync connection. Workspaces is specific to Attio and Databases to MongoDB — each maps to any object or custom field on the other side.
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. Custom objects is specific to Attio and Collections to MongoDB — each maps to any object or custom field on the other side.

How changes propagate between Attio and MongoDB

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Attio MongoDB Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

DeliveryEach detected change is applied to MongoDB as a row-level write, with types converted between the two schemas.

MongoDB Attio Sub-second propagation

DetectionChanges in MongoDB are captured at the source via change data capture — no polling loop against its API. MongoDB oplog and change streams (requires the database to run as a replica set — even single-node).

DeliveryEach detected change is written to Attio through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Attio: Subject to the platform's published API rate limits.
