Why teams connect Intercom and Reltio

Treat Intercom 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 Contacts, Companies, Conversations, Tickets from Intercom into Entities, Relations, Crosswalks, Interactions in Reltio with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Intercom 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 contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
  • 02 Push product usage events from an application database into Intercom to trigger onboarding and retention messages
  • 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

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to Reltio sync onto the matching records in Intercom, giving go-to-market teams live product context.

Internal tools without API code

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

What you can sync between Intercom 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.

Intercom objects Reltio objects How this pairing syncs
Data Events Behavioral events pushed in from product databases trigger messages and flows. Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. Data Events is specific to Intercom and Data Change Requests (DCR) to Reltio — each maps to any object or custom field on the other side.
Custom Data Attributes Typed custom fields on contacts and companies hold synced billing and usage data. Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. Custom Data Attributes is specific to Intercom and Reference Data (RDM) to Reltio — each maps to any object or custom field on the other side.
Tags Labels applied to contacts, companies, and conversations sync for routing and reporting. 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. Tags is specific to Intercom and Entities to Reltio — each maps to any object or custom field on the other side.
Segments Saved audience definitions are readable for targeting parity across tools. 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. Segments is specific to Intercom and Relations to Reltio — each maps to any object or custom field on the other side.
Admins & Teams Teammate records map conversation ownership to CRM users. 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. Admins & Teams is specific to Intercom and Crosswalks to Reltio — each maps to any object or custom field on the other side.
Articles Help center content is accessible via API for knowledge sync and audits. Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. Articles is specific to Intercom and Interactions to Reltio — each maps to any object or custom field on the other side.

How changes propagate between Intercom 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.

Intercom Reltio Sub-second propagation

DetectionIntercom notifies Stacksync of record changes through webhook events. Webhook topic subscriptions for contact, company, and conversation events, plus polling for backfill.

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

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

Rate-limit considerations

  • Intercom: Subject to per-app rate limits on the Intercom API.
  • 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.

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.
