What ships with MongoDB

Connect MongoDB for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every connection.

Real-time

Two-way sync

Changes in MongoDB instantly reflect across connected systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever MongoDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single MongoDB record.

Observability

Monitoring

Track your MongoDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions.

How it works

Set up MongoDB in minutes, without APIs.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

    Connect your apps

    Authenticate MongoDB with its native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the MongoDB objects to sync — Stacksync auto-detects the schema, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.

FAQ

MongoDB connector FAQ

What can I sync with the MongoDB connector?

MongoDB's core objects — Databases, Collections, Documents, Embedded documents and arrays and custom fields — can sync with any of 194 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to MongoDB?

Via MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management, authenticated with 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. Changes are detected as follows — 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. Stacksync manages rate limits, retries, and schema changes automatically.

Is the MongoDB connector two-way?

Yes. Changes made in MongoDB propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a MongoDB integration take to set up?

Most MongoDB integrations go live in minutes: authenticate MongoDB and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is MongoDB data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. MongoDB data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
