Why teams connect Braze and MongoDB

Mirror Braze's data into MongoDB so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Braze through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in MongoDB.

Stacksync mirrors Custom Attributes, Custom Events, Purchases, Segments from Braze into Views, Change streams, GridFS files, Databases in MongoDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Braze, so the tool and the database never disagree.

Common use cases

  • 01 Export campaign and Canvas engagement data into a warehouse for cross-channel reporting.
  • 02 Sync audience membership computed in the warehouse into Braze segments for targeting.
  • 03 Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
  • 04 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.

Common sync patterns

React to changes as they happen

Updates in Braze arrive as row changes in MongoDB, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Braze with a query

Records from Braze are ordinary rows in MongoDB; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Braze 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.

Braze objects MongoDB objects How this pairing syncs
Campaigns Message sends whose metadata and analytics are read for reporting. Documents BSON records created, updated, and deleted during syncs, keyed by _id. Campaigns is specific to Braze and Documents to MongoDB — each maps to any object or custom field on the other side.
Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Canvases is specific to Braze and Embedded documents and arrays to MongoDB — each maps to any object or custom field on the other side.
Subscription Groups Channel-level opt-in states synced with consent records in other systems. Indexes Keep lookups by sync key fast on large collections. Subscription Groups is specific to Braze and Indexes to MongoDB — each maps to any object or custom field on the other side.
Content Blocks Reusable message content referenced across campaigns. Views Read-only aggregation-defined sources for filtered sync datasets. Content Blocks is specific to Braze and Views to MongoDB — each maps to any object or custom field on the other side.
Users The central profile object, identified by external ID, Braze ID, or user aliases; the main sync target. Change streams The oplog-backed event feed that powers real-time change capture. Users is specific to Braze and Change streams to MongoDB — each maps to any object or custom field on the other side.
Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization. GridFS files Chunked file storage whose metadata can be referenced by synced documents. Custom Attributes is specific to Braze and GridFS files to MongoDB — each maps to any object or custom field on the other side.

How changes propagate between Braze 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.

Braze MongoDB Interval-based propagation

DetectionStacksync polls Braze for changes on an incremental schedule, reading only records changed since the previous pass. Braze Currents streams engagement events outward.

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

MongoDB Braze 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 Braze through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Braze: Endpoints have per-endpoint rate limits documented by Braze; batch endpoints accept multiple users per request.
