Why teams connect Reltio and Zoho CRM

Treat Zoho CRM 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 Quote, Sales Order, Purchase Order, Invoice from Zoho CRM into Data Change Requests (DCR), Reference Data (RDM), Entities, Relations in Reltio with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Zoho CRM 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 Push warehouse-computed lead scores and product signals into Zoho CRM fields for rep prioritization.
  • 02 Keep Zoho CRM accounts aligned with an ERP or accounting system on customers and invoices.
  • 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

Trigger workflows from CRM changes

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

Query the CRM like a database

Accounts, contacts, and custom objects from Zoho CRM 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 Zoho CRM, giving go-to-market teams live product context.

What you can sync between Reltio and Zoho CRM

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 Zoho CRM objects How this pairing syncs
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. Quote Synced with incremental and full sync per the Stacksync docs. Relations is specific to Reltio and Quote to Zoho CRM — 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. Sales Order Synced with incremental and full sync per the Stacksync docs. Crosswalks is specific to Reltio and Sales Order to Zoho CRM — 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. Purchase Order Synced with incremental and full sync per the Stacksync docs. Interactions is specific to Reltio and Purchase Order to Zoho CRM — 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. Invoice Synced with incremental and full sync per the Stacksync docs. Matches (Potential Matches) is specific to Reltio and Invoice to Zoho CRM — each maps to any object or custom field on the other side.
Activity Log Immutable audit trail of changes to entities and relations via /activities; read-only, used for history, lineage, and compliance reporting. Lead Synced with incremental and full sync per the Stacksync docs. Activity Log is specific to Reltio and Lead to Zoho CRM — each maps to any object or custom field on the other side.
Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. Contact Synced with incremental and full sync per the Stacksync docs. Data Change Requests (DCR) is specific to Reltio and Contact to Zoho CRM — each maps to any object or custom field on the other side.

How changes propagate between Reltio and Zoho CRM

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

Zoho CRM Reltio Sub-second propagation

DetectionZoho CRM notifies Stacksync of record changes through webhook events. Notification API (webhooks) on watched modules, with polling on Modified_Time.

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.
  • Zoho CRM: API credits are allocated per day and vary by edition.

How the Reltio and Zoho CRM 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.
