What Stacksync syncs in Reltio.

These objects sync between Reltio and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Reltio exposes them.

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.
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.
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.
Interactions
Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting.
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.
Activity Log
Immutable audit trail of changes to entities and relations via /activities; read-only, used for history, lineage, and compliance reporting.
Data Change Requests (DCR)
Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records.
Reference Data (RDM)
Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data.
API surface

How Stacksync connects to Reltio.

The connector runs on Reltio's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
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.
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. Large loads and reads use bulk create/update and the asynchronous export/jobs API rather than row-by-row calls.

Use cases

What teams run on the Reltio connector.

Reltio is a cloud-native master data management (MDM) platform owned by data governance, MDM, and data-engineering teams. It ingests customer, product, supplier, and organization records from many source systems, then matches and merges them into unified golden records governed by survivorship rules, crosswalks back to each source, typed relationships, and interactions. It is the trusted system of record for core master and reference data, so operational apps and the data warehouse read golden records out of it while source systems feed records in.

  • Master data management (MDM) leads and data stewards
  • Data engineering
  • Data governance and compliance teams
  • Enterprise architects
  • CRM and customer-data operations (RevOps)

  1. Load and continuously update Entities (customer, product, supplier, or organization golden records) in Reltio from Salesforce, SAP, or a data warehouse so the MDM hub stays current.

  2. Read unified golden-record Entities and their Crosswalks out of Reltio into Snowflake or BigQuery for analytics on a single trusted customer or product view.

  3. Push cleansed, deduplicated golden records and survivorship results from Reltio back into CRM and ERP systems so every app works from the mastered record.

  4. Sync Relations (affiliations, hierarchies, households) between Reltio and a CRM or graph so account and affiliation structures stay aligned.

  5. Feed Interactions (transactions, visits, events) into Reltio to enrich entity profiles, then read them back for 360-degree reporting.

  6. Mirror the Reltio Activity Log and change history into a database for audit, lineage, and governance reporting.

How it works

Set up Reltio in minutes, without APIs.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Reltio with its native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the Reltio objects to sync — Stacksync auto-detects the schema, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.

FAQ

Reltio connector FAQ

What can I sync with the Reltio connector?

Reltio's core objects — Entities, Relations, Crosswalks, Interactions and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Reltio?

Via 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}, authenticated with 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). Changes are detected as follows — 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.. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Reltio connector two-way?

Yes. Changes made in Reltio propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a Reltio integration take to set up?

Most Reltio integrations go live in minutes: authenticate Reltio and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Reltio data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Reltio data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
