Why teams connect Monday and Smartsheet

Stop re-entering the same information in Monday and Smartsheet: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Subitems, Column values, Groups, Updates in Monday with Users and Groups, Sheets, Rows, Columns in Smartsheet in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • 01 Mirror monday.com Boards, Groups, and Subitems into a warehouse for cross-project reporting on status and timelines without CSV exports.
  • 02 Push support tickets or orders from an operational database into monday.com Items, then read status Column values back when work completes.
  • 03 Mirror Users and Groups from an HR system or directory so sheet sharing and workspace access stay aligned with headcount changes.
  • 04 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.

Common sync patterns

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between Monday 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.

Monday objects Smartsheet objects How this pairing syncs
Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. 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. Items is specific to Monday and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Subitems is specific to Monday and Rows to Smartsheet — each maps to any object or custom field on the other side.
Column values Typed fields (status, date, people, numbers, connect-boards); polymorphic JSON usually written together via change_multiple_column_values. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Column values is specific to Monday and Columns to Smartsheet — each maps to any object or custom field on the other side.
Groups Named sections that group items inside a board; synced as a grouping attribute or category field on the row. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Groups is specific to Monday and Cells to Smartsheet — each maps to any object or custom field on the other side.
Updates Comment and activity threads attached to items; read out into a database for reporting or written back as notes. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Updates is specific to Monday and Reports to Smartsheet — each maps to any object or custom field on the other side.
Users Account members referenced by people columns; read to resolve owner and assignee IDs to names and emails. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Users is specific to Monday and Attachments to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Monday 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.

Monday Smartsheet Sub-second propagation

DetectionMonday notifies Stacksync of record changes through webhook events. Board-scoped webhooks (create_item, change_column_value, item_deleted, and similar) for real-time events.

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

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

Rate-limit considerations

  • Monday: Complexity-budget limits: a single query caps at 5M complexity points and ~10M points/min per user token (1M on trial/free) over a sliding 60s window.
  • 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.
