FAQ

AWS S3 connector FAQ

What can I sync with the AWS S3 connector?

AWS S3's core objects — Buckets, Objects, Prefixes, Object Metadata 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 AWS S3?

Via REST API (the S3 API), accessed directly or through AWS SDKs, authenticated with AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes. Changes are detected as follows — s3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback. Stacksync manages rate limits, retries, and schema changes automatically.

Is the AWS S3 connector two-way?

Yes. Changes made in AWS S3 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 an AWS S3 integration take to set up?

Most AWS S3 integrations go live in minutes: authenticate AWS S3 and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is AWS S3 data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. AWS S3 data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
