Why teams connect Kustomer and MongoDB
Treat Kustomer 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 Customers, Conversations, Messages, Companies from Kustomer 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 Kustomer 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 order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
- 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.
Trigger workflows from CRM changes
Field and stage updates in Kustomer arrive as row changes in MongoDB, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Kustomer 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 Kustomer, giving go-to-market teams live product context.
What you can sync between Kustomer 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.
| Kustomer objects | MongoDB objects | |
|---|---|---|
| Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Collections The table-like sync unit; each collection maps to a table or object in the paired system. | |
| Conversations Support threads across channels sync outward for analytics and CRM context. | Documents BSON records created, updated, and deleted during syncs, keyed by _id. | |
| Messages Individual messages within conversations support full-thread replication. | Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. | |
| Companies Organization records group customers and map to CRM accounts. | Indexes Keep lookups by sync key fast on large collections. | |
| Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | Views Read-only aggregation-defined sources for filtered sync datasets. | |
| Users Agent records map conversation ownership to people in other systems. | Change streams The oplog-backed event feed that powers real-time change capture. |

FAQ
Kustomer and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and MongoDB: authenticate both systems, choose the objects to sync (such as Kustomer's Customers and Conversations), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. 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. Stacksync manages authentication, retries, and rate limits on both sides.
-
Kustomer: Kustomer's data model centers on a customer timeline: conversations, messages, and custom object records all appear chronologically against one customer record rather than as separate tickets. MongoDB: Only ObjectId primary keys are supported for collections. Stacksync's field mapping accounts for these differences between Kustomer 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 Kustomer and MongoDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Kustomer and MongoDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Kustomer–MongoDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Kustomer and MongoDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
