Why teams connect Attio and Smartsheet

Sync what happens in Smartsheet with the customer records in Attio, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Smartsheet holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Cells, Reports, Attachments, Discussions and Comments in Smartsheet to Workspaces, Custom objects, People, Companies in Attio with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Attio, and CRM data flows the other way wherever Smartsheet can store and use it.

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 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • 04 Run a two-way dual-run when migrating to Attio from another CRM.

Common sync patterns

Where Smartsheet can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Attio sync into Smartsheet, so people working there have the context without switching tools.

Where Smartsheet supplies contact or company data

Enriched fields land directly on records in Attio, and refreshes keep them from going stale.

What you can sync between Attio 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.

Attio objects Smartsheet objects How this pairing syncs
Custom objects Workspace-defined objects that behave like standard ones in the API. 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. Custom objects is specific to Attio and Sheets to Smartsheet — each maps to any object or custom field on the other side.
People Standard person object; synced with marketing tools and warehouse person tables. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. People is specific to Attio and Rows to Smartsheet — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Companies is specific to Attio and Columns to Smartsheet — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Users is specific to Attio and Cells to Smartsheet — each maps to any object or custom field on the other side.
Deals Pipeline records; read out for revenue reporting and written to from automation. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Deals is specific to Attio and Reports to Smartsheet — each maps to any object or custom field on the other side.
Workspaces Synced with incremental and full sync per the Stacksync docs. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Workspaces is specific to Attio and Attachments to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Attio 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.

Attio Smartsheet Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

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

Rate-limit considerations

  • Attio: Subject to the platform's published API rate limits.
  • 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.
