Why teams connect AWS S3 and Braze

Get the data locked inside Braze into AWS S3 as live tables, and send results back where Braze can use them, without writing a pipeline.

Whatever Braze is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Purchases, Segments, Campaigns, Canvases from Braze into tables in AWS S3 continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in AWS S3 can also be written back into fields in Braze where the tool can use them.

Common use cases

  • Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
  • Push product usage events from a database or warehouse into Braze to trigger onboarding and retention journeys.
  • Ingest partner or vendor file drops (CSV, JSON, Parquet) from a bucket into a database or CRM as records.
  • Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.

Where Braze accepts updates: operational write-back

Segments, scores, or reference values computed in AWS S3 sync back onto records in Braze, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in AWS S3 preserves a queryable record even as data ages out of Braze or gets changed inside it.

Analytics on Braze's data

Records and events from Braze land in AWS S3 as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between AWS S3 and Braze

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.

AWS S3 objects Braze objects
Object Metadata System and user-defined metadata read alongside object contents. Purchases Transaction records logged against profiles for revenue-based targeting.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Segments Audience definitions read for membership export and campaign targeting.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Campaigns Message sends whose metadata and analytics are read for reporting.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis.
Multipart Uploads The mechanism used to write large export files reliably. Subscription Groups Channel-level opt-in states synced with consent records in other systems.
Buckets Top-level containers a sync targets; region and policy are set at this level. Content Blocks Reusable message content referenced across campaigns.

How the AWS S3 and Braze connectors work

AWS S3

Integration surface
REST API (the S3 API), accessed directly or through AWS SDKs
Authentication
AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes
Change detection
S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes

Braze

Integration surface
REST API
Authentication
REST API keys scoped to specific endpoints, issued per workspace
Change detection
Braze Currents streams engagement events outward; profile reads otherwise rely on export endpoints and polling
Capabilities
read · write
Rate limits
Endpoints have per-endpoint rate limits documented by Braze; batch endpoints accept multiple users per request
