Why teams connect Affinity and MongoDB
Treat Affinity 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 Reminders, Lists, List Entries, Persons from Affinity into Change streams, GridFS files, Databases, Collections in MongoDB with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Affinity 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
- Push enrichment data computed elsewhere into Affinity field values on list entries.
- Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
- 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.
Trigger workflows from CRM changes
Field and stage updates in Affinity arrive as row changes in MongoDB, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Affinity 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 Affinity, giving go-to-market teams live product context.
What you can sync between Affinity 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.
| Affinity objects | MongoDB objects | |
|---|---|---|
| Interactions Automatically captured emails and meetings, read for activity reporting. | Indexes Keep lookups by sync key fast on large collections. | |
| Reminders Follow-up tasks associated with people and organizations. | Views Read-only aggregation-defined sources for filtered sync datasets. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | Change streams The oplog-backed event feed that powers real-time change capture. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | GridFS files Chunked file storage whose metadata can be referenced by synced documents. | |
| Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. | Databases Logical groupings of collections that scope a sync connection. | |
| Organizations Company records matched to accounts in other systems by domain. | Collections The table-like sync unit; each collection maps to a table or object in the paired system. |

FAQ
Affinity and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Affinity and MongoDB: authenticate both systems, choose the objects to sync (such as Affinity's Interactions and Reminders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes — Stacksync ships production-grade connectors for both Affinity and MongoDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Affinity: Webhook subscriptions for record events, supplemented by polling. 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 Affinity side: Reminders, Lists, List Entries, Persons, plus custom fields where Affinity exposes them. On the MongoDB side: Change streams, GridFS files, Databases, Collections. 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.
-
Common patterns for Affinity and MongoDB: Trigger workflows from CRM changes; Query the CRM like a database; Product events onto CRM records. Field and stage updates in Affinity arrive as row changes in MongoDB, ready to drive jobs and notifications.
