Why teams connect Apollo.io and Neo4j

Treat Apollo.io like part of your database: its records live in Neo4j 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 Neo4j, where it can be queried and joined like everything else.

Stacksync mirrors People (database records), Sequences, Deals (Opportunities), Tasks and calls from Apollo.io into Labels, Indexes & Constraints, Databases, Users & Roles in Neo4j with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Apollo.io 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

  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Feed identity and access data into a graph for entitlement and blast-radius analysis.
  • Write computed relationship scores (fraud, influence, similarity) back to operational systems.

Trigger workflows from CRM changes

Field and stage updates in Apollo.io arrive as row changes in Neo4j, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Apollo.io become tables in Neo4j you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Neo4j sync onto the matching records in Apollo.io, giving go-to-market teams live product context.

What you can sync between Apollo.io and Neo4j

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.

Apollo.io objects Neo4j objects
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Labels Node type markers used to map source tables or objects onto the graph.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Users & Roles Security principals controlling what an integration credential can query or modify.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Relationships Typed, directed edges that carry the connections syncs exist to model.

How the Apollo.io and Neo4j connectors work

Apollo.io

Integration surface
REST API
Authentication
API key (passed in request headers); master keys unlock account-wide endpoints
Change detection
Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream
Capabilities
read · write
Rate limits
Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls

Neo4j

Integration surface
Bolt binary protocol with Cypher via official drivers, plus an HTTP query API
Authentication
Username/password (basic auth); enterprise deployments add SSO options
Change detection
Neo4j Change Data Capture on Enterprise and Aura streams graph changes; otherwise Cypher polling on timestamp properties
Capabilities
