Why teams connect HubSpot and Reltio

Treat HubSpot like part of your database: its records live in Reltio as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Reltio, where it can be queried and joined like everything else.

Stacksync mirrors Stages, Audit, Contact, Company from HubSpot into Matches (Potential Matches), Activity Log, Data Change Requests (DCR), Reference Data (RDM) in Reltio with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in HubSpot with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • 01 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • 02 Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • 03 Sync Relations (affiliations, hierarchies, households) between Reltio and a CRM or graph so account and affiliation structures stay aligned.
  • 04 Feed Interactions (transactions, visits, events) into Reltio to enrich entity profiles, then read them back for 360-degree reporting.

Common sync patterns

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the HubSpot API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in HubSpot arrive as row changes in Reltio, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from HubSpot become tables in Reltio you can join with application data directly.

What you can sync between HubSpot and Reltio

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.

HubSpot objects Reltio objects How this pairing syncs
Audit Synced with incremental and full sync per the Stacksync docs. 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. Audit is specific to HubSpot and Relations to Reltio — each maps to any object or custom field on the other side.
Contact Synced with incremental and full sync per the Stacksync docs. 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. Contact is specific to HubSpot and Crosswalks to Reltio — each maps to any object or custom field on the other side.
Company Synced with incremental and full sync per the Stacksync docs. Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. Company is specific to HubSpot and Interactions to Reltio — each maps to any object or custom field on the other side.
Deal Synced with incremental and full sync per the Stacksync docs. Matches (Potential Matches) Candidate duplicate pairs produced by match rules; read to review, and resolved with merge, unmerge, or not-a-match actions to control survivorship. Deal is specific to HubSpot and Matches (Potential Matches) to Reltio — each maps to any object or custom field on the other side.
Line Item Synced with incremental and full sync per the Stacksync docs. Activity Log Immutable audit trail of changes to entities and relations via /activities; read-only, used for history, lineage, and compliance reporting. Line Item is specific to HubSpot and Activity Log to Reltio — each maps to any object or custom field on the other side.
Product Synced with incremental and full sync per the Stacksync docs. Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. Product is specific to HubSpot and Data Change Requests (DCR) to Reltio — each maps to any object or custom field on the other side.

How changes propagate between HubSpot and Reltio

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.

HubSpot Reltio Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

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

Reltio HubSpot 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 HubSpot through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • HubSpot: Request limits vary by subscription tier and API type.
  • 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.

HubSpot setup guide

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.
Capabilities

Rate limits
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.
