Two-way sync
Changes in AWS S3 or Smartsheet instantly reflect in both systems. No stale data, no manual imports.
Keep AWS S3 and Smartsheet in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Whatever Smartsheet 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 Sheets, Rows, Columns, Cells from Smartsheet 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 Smartsheet where the tool can use them.
A continuously synced copy in AWS S3 preserves a queryable record even as data ages out of Smartsheet or gets changed inside it.
Records and events from Smartsheet land in AWS S3 as queryable tables, current within seconds and ready to join with the rest of the warehouse.
Combine Smartsheet's data with data from every other synced system to answer questions no single tool can.
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 | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Multipart Uploads The mechanism used to write large export files reliably. | Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | Multipart Uploads is specific to AWS S3 and Users and Groups to Smartsheet — each maps to any object or custom field on the other side. | |
| Buckets Top-level containers a sync targets; region and policy are set at this level. | Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. | Buckets is specific to AWS S3 and Sheets to Smartsheet — each maps to any object or custom field on the other side. | |
| Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Objects is specific to AWS S3 and Rows to Smartsheet — each maps to any object or custom field on the other side. | |
| Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Prefixes is specific to AWS S3 and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Object Metadata System and user-defined metadata read alongside object contents. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Object Metadata is specific to AWS S3 and Cells to Smartsheet — each maps to any object or custom field on the other side. | |
| Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Object Versions is specific to AWS S3 and Reports to Smartsheet — each maps to any object or custom field on the other side. |
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.
DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every AWS S3–Smartsheet connection.
Changes in AWS S3 or Smartsheet instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever AWS S3 or Smartsheet data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single AWS S3 or Smartsheet record.
Track your AWS S3 ⇄ Smartsheet sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between AWS S3 and Smartsheet.
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.
Authenticate AWS S3 and Smartsheet with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the AWS S3 and Smartsheet objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between AWS S3 and Smartsheet: authenticate both systems, choose the objects to sync (such as AWS S3's Multipart Uploads and Buckets), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for AWS S3 and Smartsheet: History that outlives the tool; Analytics on Smartsheet's data; Cross-tool reporting. A continuously synced copy in AWS S3 preserves a queryable record even as data ages out of Smartsheet or gets changed inside it.
AWS S3: 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. Smartsheet: REST API (v2.0). Authentication: OAuth 2.0 authorization-code flow, or a raw/personal API access token passed as a Bearer header. Stacksync manages authentication, retries, and rate limits on both sides.
Smartsheet: Reports are read-only and capped at 50,000 rows; paged report reads return at most 10,000 rows per request. AWS S3: The namespace is flat: prefixes only simulate folders, and listing performance depends on how keys are partitioned. Stacksync's field mapping accounts for these differences between AWS S3 and Smartsheet without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means AWS S3 and Smartsheet records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed AWS S3 and Smartsheet connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom AWS S3–Smartsheet integration in-house.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
