Why teams connect Reltio and Slack

Mirror Slack'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 Slack 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 Files, Reactions, Channels, Messages from Slack into Activity Log, Data Change Requests (DCR), Reference Data (RDM), Entities 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 Slack, so the tool and the database never disagree.

Common use cases

  • 01 Alert an operations channel when a data sync detects conflicts or validation failures
  • 02 Post CRM record changes into deal or account channels so the team sees updates without opening the CRM
  • 03 Mirror the Reltio Activity Log and change history into a database for audit, lineage, and governance reporting.
  • 04 Push cleansed, deduplicated golden records and survivorship results from Reltio back into CRM and ERP systems so every app works from the mastered record.

Common sync patterns

React to changes as they happen

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

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Slack with a query

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

What you can sync between Reltio and Slack

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 Slack objects How this pairing syncs
Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. Channels Conversations (public, private, DMs) that messages are read from and posted to. Reference Data (RDM) is specific to Reltio and Channels to Slack — 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. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. Entities is specific to Reltio and Messages to Slack — 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. Threads Replies grouped under a parent message timestamp, preserved when archiving conversations. Relations is specific to Reltio and Threads to Slack — 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. Users Workspace members with profile fields, synced against HR systems and identity providers. Crosswalks is specific to Reltio and Users to Slack — 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. User groups Handles like @support that map to teams in external systems. Interactions is specific to Reltio and User groups to Slack — each maps to any object or custom field on the other side.
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. Files Uploads attached to messages, retrievable for archiving. Matches (Potential Matches) is specific to Reltio and Files to Slack — each maps to any object or custom field on the other side.

How changes propagate between Reltio and Slack

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

Slack Reltio Sub-second propagation

DetectionSlack notifies Stacksync of record changes through webhook events. Events API webhooks, delivered over HTTP callbacks or Socket Mode.

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.
  • Slack: Per-method rate limit tiers; message posting is additionally limited per channel.

How the Reltio and Slack 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.
