Why teams connect Lusha and Reltio

Mirror Lusha's data into Reltio so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Lusha is a read-only source: Stacksync reads its data in real time and delivers it into Reltio, so Reltio always reflects the current state of Lusha — without exports, scripts, or schedulers.

Engineers integrate with tools like Lusha 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 Email Addresses, Phone Numbers, Prospecting Results, Bulk Enrichment Requests from Lusha into Reference Data (RDM), Entities, Relations, Crosswalks 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 Lusha, so the tool and the database never disagree.

Common use cases

  • 01 Build prospecting lists from Lusha search results and sync them into the CRM as leads.
  • 02 Re-verify stale contact data on a schedule and flag records that no longer resolve.
  • 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

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 Lusha with a query

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

Automate Lusha from your codebase

Write to the synced tables in Reltio and Stacksync propagates the change into Lusha, replacing custom integration code.

What you can sync between Lusha 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.

Lusha objects Reltio objects How this pairing syncs
Company Profiles Firmographic records (industry, size, location) appended to account or company rows. Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. Company Profiles is specific to Lusha and Data Change Requests (DCR) to Reltio — each maps to any object or custom field on the other side.
Email Addresses Work emails written into CRM contact fields during enrichment. Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. Email Addresses is specific to Lusha and Reference Data (RDM) to Reltio — each maps to any object or custom field on the other side.
Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows. 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. Phone Numbers is specific to Lusha and Entities to Reltio — each maps to any object or custom field on the other side.
Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists. 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. Prospecting Results is specific to Lusha and Relations to Reltio — each maps to any object or custom field on the other side.
Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls. 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. Bulk Enrichment Requests is specific to Lusha and Crosswalks to Reltio — each maps to any object or custom field on the other side.
Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup. Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. Person Profiles is specific to Lusha and Interactions to Reltio — each maps to any object or custom field on the other side.

How changes propagate between Lusha 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.

Lusha Reltio Interval-based propagation

DetectionStacksync polls Lusha for changes on an incremental schedule, reading only records changed since the previous pass. Data is fetched on demand per lookup, so syncs poll or trigger enrichment when source records change.

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

Reltio Lusha 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.

DeliveryLusha does not accept inbound record writes, so this direction carries requests rather than records: Lusha's output flows back as field updates on the originating Reltio records.

Rate-limit considerations

  • Lusha: Lookups consume credits and are subject to the platform's API rate limits.
  • 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.
