Why teams connect Sharepoint and Slack

Land the records and documents that build up in Slack into Sharepoint as they are created, and surface Sharepoint's file details on the Slack records that point to them, without an export job to maintain.

Slack and Sharepoint hold different kinds of data. Slack carries records and the activity around them — the tickets, messages, orders, or issues a team works through, often with documents attached. Sharepoint holds files and the metadata that describes them. Where the two meet is narrow but real: much of what Slack produces has to be kept somewhere durable, and many of the files Sharepoint stores are the very documents Slack's records point to.

Stacksync syncs Files, Reactions, Channels, Messages in Slack with Sites, Lists, List items, Drive items (document libraries) in Sharepoint in real time. Records and attachments created in Slack are written into Sharepoint as objects or files within seconds of being created. In the other direction, the metadata Sharepoint keeps about those files — name, location, owner, modified date — flows back onto the matching record in Slack, so people see the current document without leaving the tool. Field-level mapping controls exactly what crosses over and in which direction, so you keep a durable copy of what matters without an extract to schedule or a nightly dump that leaves the copy a day behind.

Common use cases

  • 01 Create or update records in a database when specific messages or reactions occur in a channel
  • 02 Alert an operations channel when a data sync detects conflicts or validation failures
  • 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

Feed a data lake or downstream pipeline

Structured records from Slack land in Sharepoint as objects a data lake, search index, or processing pipeline can read, without a custom extract to build and babysit.

Archive what Slack produces into Sharepoint

Records and events from Slack — tickets, messages, orders, or issues — are written into Sharepoint as objects or files as they change, giving you a durable, addressable copy for retention and audit.

Where Slack generates attachments: keep the files in Sharepoint

Documents attached to records in Slack land in the storage system automatically, with the source record holding a link back, so files live in one governed place instead of inside the tool.

What you can sync between Sharepoint and Slack

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.

Sharepoint objects Slack objects How this pairing syncs
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. Channels Conversations (public, private, DMs) that messages are read from and posted to. Lists is specific to Sharepoint and Channels to Slack — each maps to any object or custom field on the other side.
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. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. List items is specific to Sharepoint and Messages to Slack — each maps to any object or custom field on the other side.
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. Threads Replies grouped under a parent message timestamp, preserved when archiving conversations. Drive items (document libraries) is specific to Sharepoint and Threads to Slack — each maps to any object or custom field on the other side.
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. Users Workspace members with profile fields, synced against HR systems and identity providers. Columns and content types is specific to Sharepoint and Users to Slack — each maps to any object or custom field on the other side.
Permissions and sharing Role assignments and sharing links on sites, list items, and drive items; read and written to manage access, requiring Sites.Manage.All or Sites.FullControl.All scopes. User groups Handles like @support that map to teams in external systems. Permissions and sharing is specific to Sharepoint and User groups to Slack — each maps to any object or custom field on the other side.
Site pages Modern site pages via /sites/{id}/pages; read page content, layout, and metadata for indexing and content governance. Files Uploads attached to messages, retrievable for archiving. Site pages is specific to Sharepoint and Files to Slack — each maps to any object or custom field on the other side.

How changes propagate between Sharepoint and Slack

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.

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

Rate-limit considerations

  • 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.
  • Slack: Per-method rate limit tiers; message posting is additionally limited per channel.

How the Sharepoint and Slack connectors work

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.
