Why teams connect Reltio and Smartsheet
Mirror Smartsheet's data into Reltio 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 Reltio.
Stacksync mirrors Rows, Columns, Cells, Reports from Smartsheet into Entities, Relations, Crosswalks, Interactions in Reltio 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 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 Push cleansed, deduplicated golden records and survivorship results from Reltio back into CRM and ERP systems so every app works from the mastered record.
- 04 Sync Relations (affiliations, hierarchies, households) between Reltio and a CRM or graph so account and affiliation structures stay aligned.
Common sync patterns
Read Smartsheet with a query
Records from Smartsheet are ordinary rows in Reltio; 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 Reltio 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 Reltio, so triggers, jobs, and services can respond in near real time.
What you can sync between Reltio 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.
| Reltio objects | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. | Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | Data Change Requests (DCR) is specific to Reltio and Users and Groups to Smartsheet — each maps to any object or custom field on the other side. | |
| Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. | 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. | Reference Data (RDM) is specific to Reltio and Sheets to Smartsheet — each maps to any object or custom field on the other side. | |
| Entities Golden records for each configured entity type (for example Organization, Individual/Contact, Location, or Product); full CRUD via /entities, so records are created, updated, and deleted, and Reltio matches and merges them by survivorship rules. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Entities is specific to Reltio and Rows to Smartsheet — each maps to any object or custom field on the other side. | |
| Relations Typed relationships between two entities (affiliations, hierarchies, employment, households); read and written via /relations to keep account hierarchies and affiliation graphs aligned across systems. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Relations is specific to Reltio and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Crosswalks Per-entity references to the source systems and their record IDs; written when loading records so Reltio ties each source contribution to a golden record, and read to trace lineage back to origin systems. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Crosswalks is specific to Reltio and Cells to Smartsheet — each maps to any object or custom field on the other side. | |
| Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Interactions is specific to Reltio and Reports to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between Reltio 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.
Reltio Smartsheet Interval-based propagation
DetectionStacksync polls Reltio for changes on an incremental schedule, reading only records changed since the previous pass. Polling the REST API on updateTime (epoch-ms), for example filter=gt(updateTime,<timestamp>), for entities and relations changed past a stored.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet Reltio 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 Reltio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Reltio: Reltio applies per-tenant API throttling and returns HTTP 429 (Too Many Requests) when limits are exceeded; there is no single fixed request-per-second cap published for all tenants, and throttling is tuned per tenant and environment. Large loads and reads use bulk create/update and the asynchronous export/jobs API rather than row-by-row calls.
- 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.

How the Reltio and Smartsheet connectors work
Reltio
- Integration surface
- Reltio REST API (Data API) — /entities, /relations, /interactions, /activities, plus Match, RDM (reference data), and Data Change Request endpoints; base URL https://{environment}.reltio.com/reltio/api/{tenantId}
- Authentication
- OAuth 2.0 bearer tokens obtained from Reltio's central auth server (POST https://auth.reltio.com/oauth/token, client-credentials or password grant, application/x-www-form-urlencoded) and sent as Authorization: Bearer <token>; access tokens expire after about 60 minutes and are renewed with a refresh token, and are scoped per API (entities_api, relations_api, interactions_api, configuration_api, graphs_api)
- Change detection
- Polling the REST API on updateTime (epoch-ms), for example filter=gt(updateTime,<timestamp>), for entities and relations changed past a stored watermark. Reltio has no CDC log external tools consume; separately, Reltio's event streaming can publish entity change events (created, changed, removed) to a customer-configured message queue (Amazon SQS/SNS, Google Pub/Sub, Azure Service Bus, or Kafka), which is a queue feed rather than HTTP webhooks.
