Why teams connect Clearbit and MongoDB
Treat Clearbit like part of your database: its records live in MongoDB as real tables, and writes in either place sync to the other in seconds.
Clearbit is a read-only source: Stacksync reads its data in real time and delivers it into MongoDB, so MongoDB always reflects the current state of Clearbit — without exports, scripts, or schedulers.
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.
Common use cases
- 01 Refresh firmographic fields on existing accounts on a schedule so segmentation stays current.
- 02 Enrich new CRM leads with person and company attributes as they are created, keyed by email and domain.
- 03 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.
- 04 Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
Common sync patterns
Product events onto CRM records
Signup, usage, or lifecycle changes written to MongoDB sync onto the matching records in Clearbit, 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 Clearbit API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Clearbit arrive as row changes in MongoDB, ready to drive jobs and notifications.
What you can sync between Clearbit 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.
| Clearbit objects | MongoDB objects | How this pairing syncs | |
|---|---|---|---|
| Persons Individual profiles looked up by email and used to enrich contacts and leads. | Indexes Keep lookups by sync key fast on large collections. | Persons is specific to Clearbit and Indexes to MongoDB — each maps to any object or custom field on the other side. | |
| Reveal matches IP-to-company resolutions used to identify anonymous website traffic. | Views Read-only aggregation-defined sources for filtered sync datasets. | Reveal matches is specific to Clearbit and Views to MongoDB — each maps to any object or custom field on the other side. | |
| Name-to-domain lookups Company name resolution used to normalize account records before enrichment. | Change streams The oplog-backed event feed that powers real-time change capture. | Name-to-domain lookups is specific to Clearbit and Change streams to MongoDB — each maps to any object or custom field on the other side. | |
| Enrichment attributes The firmographic and technographic fields appended to destination records. | GridFS files Chunked file storage whose metadata can be referenced by synced documents. | Enrichment attributes is specific to Clearbit and GridFS files to MongoDB — each maps to any object or custom field on the other side. | |
| Companies Firmographic profiles looked up by domain and merged into account records. | Databases Logical groupings of collections that scope a sync connection. | Companies is specific to Clearbit and Databases to MongoDB — each maps to any object or custom field on the other side. |
How changes propagate between Clearbit 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.
Clearbit MongoDB Sub-second propagation
DetectionClearbit notifies Stacksync of record changes through webhook events. On-demand lookups.
DeliveryEach detected change is applied to MongoDB as a row-level write, with types converted between the two schemas.
MongoDB Clearbit 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).
DeliveryClearbit does not accept inbound record writes, so this direction carries requests rather than records: Clearbit's output flows back as field updates on the originating MongoDB records.
Rate-limit considerations
- Clearbit: Subject to plan-based API rate limits and lookup volumes.

FAQ
Clearbit and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Clearbit and MongoDB — Clearbit is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
On the Clearbit side: Reveal matches, Name-to-domain lookups, Enrichment attributes, Companies, plus custom fields where Clearbit exposes them. On the MongoDB side: Embedded documents and arrays, Indexes, Views, Change streams. Stacksync auto-detects both schemas and converts types between the two systems.
-
Clearbit is a read-only source, so this integration runs one-way: Stacksync reads from Clearbit in real time and delivers into MongoDB. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for Clearbit and MongoDB: Product events onto CRM records; Internal tools without API code; Trigger workflows from CRM changes. Signup, usage, or lifecycle changes written to MongoDB sync onto the matching records in Clearbit, giving go-to-market teams live product context.
-
Clearbit: REST API (separate endpoints per product: Enrichment, Reveal). Authentication: API key (bearer secret key). 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.
-
Clearbit: Clearbit was acquired by HubSpot in 2023 and its capabilities are being folded into HubSpot's Breeze Intelligence, which affects the standalone API's long-term availability. 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 Clearbit and MongoDB without custom code.
