Two-way sync
Changes in Affinity or Reltio instantly reflect in both systems. No stale data, no manual imports.
Keep Affinity and Reltio in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Persons, Organizations, Opportunities, Field Values from Affinity into Reference Data (RDM), Entities, Relations, Crosswalks in Reltio with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Affinity 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.
Field and stage updates in Affinity arrive as row changes in Reltio, ready to drive jobs and notifications.
Accounts, contacts, and custom objects from Affinity become tables in Reltio you can join with application data directly.
Signup, usage, or lifecycle changes written to Reltio sync onto the matching records in Affinity, giving go-to-market teams live product context.
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.
| Affinity objects | Reltio objects | How this pairing syncs | |
|---|---|---|---|
| Interactions Automatically captured emails and meetings, read for activity reporting. | Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. | Field Values is specific to Affinity and Data Change Requests (DCR) to Reltio — each maps to any object or custom field on the other side. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. | Notes is specific to Affinity and Reference Data (RDM) to Reltio — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | 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. | Reminders is specific to Affinity and Entities to Reltio — each maps to any object or custom field on the other side. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | 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. | Lists is specific to Affinity and Relations to Reltio — each maps to any object or custom field on the other side. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | 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. | List Entries is specific to Affinity and Crosswalks to Reltio — each maps to any object or custom field on the other side. |
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.
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
DeliveryEach detected change is written to Reltio through its API, with automatic retries and rate-limit backoff.
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.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Affinity–Reltio connection.
Changes in Affinity or Reltio instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Affinity or Reltio data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Affinity or Reltio record.
Track your Affinity ⇄ Reltio sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Affinity and Reltio.
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.
Authenticate Affinity and Reltio with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Affinity and Reltio objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Affinity and Reltio: authenticate both systems, choose the objects to sync (such as Affinity's Interactions and Field Values), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Affinity and Reltio: Trigger workflows from CRM changes; Query the CRM like a database; Product events onto CRM records. Field and stage updates in Affinity arrive as row changes in Reltio, ready to drive jobs and notifications.
Affinity: REST API. Authentication: API key. Reltio: 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). Stacksync manages authentication, retries, and rate limits on both sides.
Affinity: The data model centers on lists: a person, organization, or opportunity gains list-specific field values only through its list entry, so syncs must address both the entity and the entry. Reltio: Reltio tenants are environment- and region-specific: the REST base URL is https://{environment}.reltio.com/reltio/api/{tenantId}, so the host and tenant ID must match where the tenant is provisioned. Stacksync's field mapping accounts for these differences between Affinity and Reltio without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Affinity and Reltio records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Affinity and Reltio connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Affinity–Reltio integration in-house.
