Why teams connect Microsoft Graph and Smartsheet

Connect the tickets, records, and events in Smartsheet to the systems engineering runs in Microsoft Graph, kept current in real time and in both directions.

Smartsheet is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Microsoft Graph is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Users and Groups, Sheets, Rows, Columns in Smartsheet with Contacts, Drive items (OneDrive & SharePoint), Teams messages and chats, Planner tasks in Microsoft Graph field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

Common use cases

  • 01 Pull Reports and Sheets into a warehouse for cross-project reporting and dashboards without manual CSV exports.
  • 02 Mirror Users and Groups from an HR system or directory so sheet sharing and workspace access stay aligned with headcount changes.
  • 03 Sync Outlook Calendar events and Contacts two-way with a CRM so reps' meetings and the people they meet stay aligned across both systems.
  • 04 Send Outlook mail through the sendMail action when a database or CRM record changes, then read replies back onto the same record.

Common sync patterns

Where Microsoft Graph watches operations: live volumes for visibility

Open items, throughput, and error counts from Smartsheet replicate into Microsoft Graph, so the operational view reflects what is actually happening in the business.

One shared record across both systems

Where both systems keep records for the same contacts, items, or users, a correction in either updates the other, ending dual maintenance and keeping IDs aligned for every other flow.

Where Microsoft Graph tracks engineering work: requests become issues

A ticket or request raised in Smartsheet opens or updates a matching issue in Microsoft Graph, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.

What you can sync between Microsoft Graph and Smartsheet

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.

Microsoft Graph objects Smartsheet objects How this pairing syncs
Calendar events Outlook events via /users/{id}/events; read and write meetings, attendees, and recurrence, and accept or decline invitations. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Calendar events is specific to Microsoft Graph and Rows to Smartsheet — each maps to any object or custom field on the other side.
Contacts Personal Outlook contacts via /users/{id}/contacts; full create, read, update, delete, synced two-way with CRM person records. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Contacts is specific to Microsoft Graph and Columns to Smartsheet — each maps to any object or custom field on the other side.
Drive items (OneDrive & SharePoint) Files and folders via /drives and /me/drive; read and write items, upload and download content, and read per-item metadata. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Drive items (OneDrive & SharePoint) is specific to Microsoft Graph and Cells to Smartsheet — each maps to any object or custom field on the other side.
Teams messages and chats Channel messages and chats via /teams/{id}/channels and /chats; read message history and post new messages for alerts and archiving. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Teams messages and chats is specific to Microsoft Graph and Reports to Smartsheet — each maps to any object or custom field on the other side.
Planner tasks Plans, buckets, and tasks via /planner; read and write task status, assignments, and due dates to keep project state in sync. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Planner tasks is specific to Microsoft Graph and Attachments to Smartsheet — each maps to any object or custom field on the other side.
Users Entra ID user accounts read and written via /users; create, update profile attributes, and enable or disable accounts with User.ReadWrite.All. Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. Users is specific to Microsoft Graph and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Microsoft Graph and Smartsheet

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.

Microsoft Graph Smartsheet Sub-second propagation

DetectionMicrosoft Graph notifies Stacksync of record changes through webhook events. Delta query (change tracking) returns created, updated, and deleted items since the last deltaLink for users, groups, mail, events, contacts, and.

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

Smartsheet Microsoft Graph Sub-second propagation

DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.

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

Rate-limit considerations

  • Microsoft Graph: Throttled per app and per tenant, returning HTTP 429 with a Retry-After header; limits vary by service — the Outlook mail service allows about 10,000 requests per 10 minutes per app per mailbox with up to 4 concurrent requests, and delta and subscription tokens expire and must be renewed.
  • Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.

How the Microsoft Graph and Smartsheet connectors work

Microsoft Graph

Integration surface
Microsoft Graph unified REST API (v1.0 and beta) at graph.microsoft.com, spanning Microsoft 365 services — Entra ID, Outlook mail and calendar, OneDrive and SharePoint, Teams, and Planner; supports 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 Mail.ReadWrite, Calendars.ReadWrite, Files.ReadWrite.All, User.ReadWrite.All, and Group.ReadWrite.All; application permissions require tenant admin consent.
Change detection
Delta query (change tracking) returns created, updated, and deleted items since the last deltaLink for users, groups, mail, events, contacts, and driveItems; change-notification subscriptions (webhooks) POST near-real-time notifications to a notification URL and must be renewed before they expire.
