Why teams connect Seismic and Smartsheet

Sync what happens in Smartsheet with the customer records in Seismic, 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 Users and Groups, Sheets, Rows, Columns in Smartsheet to Reporting Activities, Library Content, Content Versions, Users in Seismic with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Seismic, and CRM data flows the other way wherever Smartsheet can store and use it.

Common use cases

  • 01 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 02 Write records from a CRM or ERP into Smartsheet Rows so ops teams manage intake and status in a grid, then push status Cells back to the source.
  • 03 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 04 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.

Common sync patterns

Where Smartsheet can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Seismic 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 Seismic, and refreshes keep them from going stale.

What you can sync between Seismic 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.

Seismic objects Smartsheet objects How this pairing syncs
Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Reporting Activities is specific to Seismic and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. 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. Library Content is specific to Seismic and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Content Versions is specific to Seismic and Rows to Smartsheet — each maps to any object or custom field on the other side.
Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Users is specific to Seismic and Columns to Smartsheet — each maps to any object or custom field on the other side.
User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. User Groups is specific to Seismic and Cells to Smartsheet — each maps to any object or custom field on the other side.
Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Teamsites is specific to Seismic and Reports to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Seismic 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.

Seismic Smartsheet Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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

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

Rate-limit considerations

  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
  • 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.
