Why teams connect AWS S3 and Sharepoint

Bridge query-ready tables and stored files: AWS S3 and Sharepoint keep the same records in step, in real time, in both directions.

AWS S3 keeps the tables and query results a business reports on; Sharepoint keeps the raw files, documents, and objects that the same business produces and shares. The two overlap wherever a dataset lives as both — a file dropped in Sharepoint that has to become rows in AWS S3, or a result in AWS S3 that people downstream need back as a file in Sharepoint. When that overlap is bridged by manual export and import or an overnight job, one side spends the day working from a stale copy.

Stacksync syncs Event Notifications, Access Points, Multipart Uploads, Buckets in AWS S3 with Sites, Lists, List items, Drive items (document libraries) in Sharepoint field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Stage bulk loads for warehouses that ingest from object storage.
  • 02 Archive change history from ongoing syncs as timestamped files for audit and replay.
  • 03 Stream list and library changes through delta query and change-notification webhooks into a warehouse for audit, access-review, and reporting.
  • 04 Two-way sync SharePoint List items with a database table so internal apps read and write structured records in SQL without calling the SharePoint API directly.

Common sync patterns

Where AWS S3 computes the labels: push them onto the files

Classifications, scores, or status derived in AWS S3 are written back onto the matching Sites, Lists, List items, Drive items (document libraries) in Sharepoint as metadata or tags, so the file store reflects what analytics decided.

Where Sharepoint receives the raw files: land them as query-ready rows

Files and exports that arrive in Sharepoint are parsed into Event Notifications, Access Points, Multipart Uploads, Buckets in AWS S3 as they land, so analysts query current data instead of waiting on the next scheduled load.

Where Sharepoint is the shared drive: publish results back as files

Curated tables and query results from AWS S3 are written to Sharepoint as files the rest of the business can open, keeping the shared copy current without a hand-run export.

What you can sync between AWS S3 and Sharepoint

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 Sharepoint objects How this pairing syncs
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Site pages Modern site pages via /sites/{id}/pages; read page content, layout, and metadata for indexing and content governance. Access Points is specific to AWS S3 and Site pages to Sharepoint — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. Sites SharePoint site collections and subsites via /sites; read site properties and discover the document libraries (drives) and lists each site contains, addressed by hostname and site path or site ID. Multipart Uploads is specific to AWS S3 and Sites to Sharepoint — 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. Lists Custom lists and libraries via /sites/{id}/lists; create and read lists along with their columns and content types so a target system can mirror or provision list definitions. Buckets is specific to AWS S3 and Lists to Sharepoint — 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. List items Rows in a SharePoint list via /lists/{id}/items with a fields facet of column values; full create, read, update, and delete, synced two-way with database rows. Objects is specific to AWS S3 and List items to Sharepoint — 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. Drive items (document libraries) Files and folders in a library's drive via /drives and /drive/root; upload, download, move, delete, and read per-item metadata, synced two-way with a store. Prefixes is specific to AWS S3 and Drive items (document libraries) to Sharepoint — each maps to any object or custom field on the other side.
Object Metadata System and user-defined metadata read alongside object contents. Columns and content types Field definitions and content types on a site or list; read the schema and create columns so database fields map cleanly onto SharePoint list fields. Object Metadata is specific to AWS S3 and Columns and content types to Sharepoint — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 and Sharepoint

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.

AWS S3 Sharepoint Sub-second propagation

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

Sharepoint AWS S3 Sub-second propagation

DetectionSharepoint notifies Stacksync of record changes through webhook events. Delta query (pull) tracks created, updated, and deleted list items (/lists/{id}/items/delta) and drive items (/drives/{id}/root/delta) since the last.

DeliveryEach detected change is written to AWS S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
  • Sharepoint: SharePoint Online throttles per app, returning HTTP 429 (or 503) with a Retry-After header in seconds and IETF RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset headers; throttled requests still count toward limits, so clients honor the greater of Retry-After and RateLimit-Reset with exponential backoff.

How the AWS S3 and Sharepoint 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

Sharepoint

Integration surface
Microsoft Graph REST API (graph.microsoft.com/v1.0 and beta) covering SharePoint sites, lists, list items, columns, content types, and document-library drives and drive items; plus the classic SharePoint REST API (_api/web) and CSOM. Supports Graph JSON $batch (up to 20 requests per call).
Authentication
OAuth 2.0 via the Microsoft identity platform (Microsoft Entra ID). An app registration holds delegated or application (app-only) scopes such as Sites.Read.All, Sites.ReadWrite.All, Sites.Selected, Sites.Manage.All, or Sites.FullControl.All, plus Files.ReadWrite.All for drive content; application permissions require tenant admin consent.
Change detection
Delta query (pull) tracks created, updated, and deleted list items (/lists/{id}/items/delta) and drive items (/drives/{id}/root/delta) since the last deltaLink; change-notification subscriptions (push webhooks) POST near-real-time notifications for list and drive/root changes to a notification URL and must be renewed before they expire. Classic SharePoint list webhooks are also available.
Capabilities

Rate limits
SharePoint Online throttles per app, returning HTTP 429 (or 503) with a Retry-After header in seconds and IETF RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset headers; throttled requests still count toward limits, so clients honor the greater of Retry-After and RateLimit-Reset with exponential backoff.
