Why teams connect Eloqua and Neo4j

Give your team Eloqua's contacts, campaigns, and engagement in Neo4j: query them with SQL, push audiences built from your own data back to Eloqua, and skip the marketing API.

Eloqua holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in Neo4j, hard to get into campaigns without manual exports.

Stacksync mirrors Contact Lists and Segments, Contacts, Accounts, Custom Data Objects from Eloqua into Relationships, Properties, Labels, Indexes & Constraints in Neo4j field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in Neo4j, from usage, orders, or account status, sync back into Eloqua to drive campaigns and ads, with Eloqua kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Write computed relationship scores (fraud, influence, similarity) back to operational systems.
  • 02 Keep a customer-360 graph continuously updated from ERP, CRM, and support sources.
  • 03 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.
  • 04 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.

Common sync patterns

React to marketing changes as row changes

A new lead, form fill, or list change in Eloqua arrives as a row change in Neo4j, so scoring, jobs, and notifications run in the tooling your team already uses.

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

Query Eloqua like a database

Contacts, leads, audiences, and campaign metrics from Eloqua live in Neo4j as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.

What you can sync between Eloqua 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.

Eloqua objects Neo4j objects How this pairing syncs
Activities Engagement events (email opens, clicks, form submits, bounces, page views, subscribes/unsubscribes) exported through the Bulk API activities export; read-only feed for scoring and attribution. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes. Activities is specific to Eloqua and Nodes to Neo4j — each maps to any object or custom field on the other side.
Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Relationships Typed, directed edges that carry the connections syncs exist to model. Campaigns is specific to Eloqua and Relationships to Neo4j — each maps to any object or custom field on the other side.
Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Properties Key-value attributes on both nodes and relationships, mapped from source fields. Emails is specific to Eloqua and Properties to Neo4j — each maps to any object or custom field on the other side.
Forms and Form Submits Form definitions and their submission data, accessed through the Application REST API; submissions read out into a warehouse for lead capture and analysis. Labels Node type markers used to map source tables or objects onto the graph. Forms and Form Submits is specific to Eloqua and Labels to Neo4j — each maps to any object or custom field on the other side.
Contact Lists and Segments Shared lists (static) and segments (dynamic audiences); Contacts are added to or removed from shared lists based on lifecycle stage computed downstream. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast. Contact Lists and Segments is specific to Eloqua and Indexes & Constraints to Neo4j — each maps to any object or custom field on the other side.
Contacts Core person records, keyed on email address as the unique identifier; imported/exported via the Bulk API and upserted on email, synced two-way with CRM, warehouse, and app databases. Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs. Contacts is specific to Eloqua and Databases to Neo4j — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Neo4j

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.

Eloqua Neo4j Interval-based propagation

DetectionStacksync polls Eloqua for changes on an incremental schedule, reading only records changed since the previous pass. Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax.

DeliveryEach detected change is written to Neo4j through its API, with automatic retries and rate-limit backoff.

Neo4j Eloqua Sub-second propagation

DetectionChanges in Neo4j are captured at the source via change data capture — no polling loop against its API. Neo4j Change Data Capture on Enterprise and Aura streams graph changes.

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

Rate-limit considerations

  • Eloqua: Per-instance soft limits by sync type (Export 2,000/hr, Import 2,000/hr, Sync Action 4,000/hr); 32 MB cap per POST to a staging area and 50,000 records per retrieve batch.
