Why teams connect Smartsheet and Twenty CRM
Sync what happens in Smartsheet with the customer records in Twenty CRM, 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 Reports, Attachments, Discussions and Comments, Users and Groups in Smartsheet to Companies, Opportunities, Tasks, Notes in Twenty CRM with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Twenty CRM, and CRM data flows the other way wherever Smartsheet can store and use it.
Common use cases
- 01 Mirror Users and Groups from an HR system or directory so sheet sharing and workspace access stay aligned with headcount changes.
- 02 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
- 03 Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
- 04 Two-way sync of People and Companies between Twenty and a production Postgres database so engineers can query CRM data with SQL.
Common sync patterns
Where Smartsheet supplies contact or company data
Enriched fields land directly on records in Twenty CRM, and refreshes keep them from going stale.
Where Smartsheet can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Twenty CRM sync into Smartsheet, so people working there have the context without switching tools.
What you can sync between Smartsheet and Twenty CRM
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.
| Smartsheet objects | Twenty CRM objects | How this pairing syncs | |
|---|---|---|---|
| Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. | Attachments Files linked to records. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. | Workspace Members User accounts used for record ownership and assignment mapping. | Discussions and Comments is specific to Smartsheet and Workspace Members to Twenty CRM — each maps to any object or custom field on the other side. | |
| Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | People Individual contact records with emails, phones, and company links; a core target for contact syncs. | Users and Groups is specific to Smartsheet and People to Twenty CRM — each maps to any object or custom field on the other side. | |
| 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. | Companies Account-level records that group people and opportunities. | Sheets is specific to Smartsheet and Companies to Twenty CRM — each maps to any object or custom field on the other side. | |
| Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Opportunities Deal records tracked through pipeline stages, synced for forecasting. | Rows is specific to Smartsheet and Opportunities to Twenty CRM — each maps to any object or custom field on the other side. | |
| Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Tasks To-dos linked to people, companies, or deals. | Columns is specific to Smartsheet and Tasks to Twenty CRM — each maps to any object or custom field on the other side. |
How changes propagate between Smartsheet and Twenty CRM
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.
Smartsheet Twenty CRM 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 Twenty CRM through its API, with automatic retries and rate-limit backoff.
Twenty CRM Smartsheet Sub-second propagation
DetectionTwenty CRM notifies Stacksync of record changes through webhook events. Webhooks on record create, update, and delete events, or polling on record update timestamps.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- 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.
- Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.
