Why teams connect PostgreSQL and Smartsheet

Mirror Smartsheet's data into PostgreSQL so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Smartsheet through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in PostgreSQL.

Stacksync mirrors Discussions and Comments, Users and Groups, Sheets, Rows from Smartsheet into Materialized Views, Schemas, Columns, Primary and Unique Keys in PostgreSQL and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Smartsheet, so the tool and the database never disagree.

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 Let an application write to its own database and have those rows appear as records in business systems in near real time
  • 04 Consolidate data from several microservice databases into one operational Postgres store

Common sync patterns

Read Smartsheet with a query

Records from Smartsheet are ordinary rows in PostgreSQL; join them, index them, and use them in application logic without touching the vendor API.

Automate Smartsheet from your codebase

Write to the synced tables in PostgreSQL and Stacksync propagates the change into Smartsheet, replacing custom integration code.

React to changes as they happen

Updates in Smartsheet arrive as row changes in PostgreSQL, so triggers, jobs, and services can respond in near real time.

What you can sync between PostgreSQL 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.

PostgreSQL objects Smartsheet objects How this pairing syncs
Columns Field-level mapping targets; types are mapped to the connected system's field types. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences Generate surrogate keys for rows created by inbound syncs. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Sequences is specific to PostgreSQL and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. 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 Types and Enums is specific to PostgreSQL and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Tables is specific to PostgreSQL and Rows to Smartsheet — each maps to any object or custom field on the other side.
Views Read-side projections used to expose joined or filtered data to a sync. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Views is specific to PostgreSQL and Cells to Smartsheet — each maps to any object or custom field on the other side.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Materialized Views is specific to PostgreSQL and Reports to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between PostgreSQL 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.

PostgreSQL Smartsheet Sub-second propagation

DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.

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

Smartsheet PostgreSQL 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 applied to PostgreSQL as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.
  • 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.
