Two-way sync
Changes in Eloqua or HubSpot instantly reflect in both systems. No stale data, no manual imports.
Keep Eloqua and HubSpot in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
HubSpot owns the customer relationship and the pipeline; Eloqua runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.
Stacksync syncs Quote, Goal, Owner, Pipeline in HubSpot with Activities, Campaigns, Emails, Forms and Form Submits in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — HubSpot can own account and opportunity status while Eloqua owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Opens, clicks, form fills, event attendance, or ad responses recorded in Eloqua post back to the contact or account in HubSpot, so reps see interest before they reach out.
Status, stage, or score set in one system updates the matching record in the other, so a lead marketing is still nurturing is not worked as sales-ready, and a closed account stops receiving prospecting.
Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in HubSpot, so who receives a campaign reflects current pipeline reality instead of a stale export.
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 | HubSpot objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Contact Synced with incremental and full sync per the Stacksync docs. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| 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. | Company Synced with incremental and full sync per the Stacksync docs. | Contact Lists and Segments is specific to Eloqua and Company to HubSpot — each maps to any object or custom field on the other side. | |
| Accounts Company records linked to Contacts via the account-linkage field; moved through the Bulk API and typically mastered in a CRM or ERP and written into Eloqua. | Deal Synced with incremental and full sync per the Stacksync docs. | Accounts is specific to Eloqua and Deal to HubSpot — each maps to any object or custom field on the other side. | |
| Custom Data Objects Auxiliary data tables (CDOs) linked to Contacts for records like event registrations or purchases; synced via the Bulk API so nurture campaigns can branch on them. | Line Item Synced with incremental and full sync per the Stacksync docs. | Custom Data Objects is specific to Eloqua and Line Item to HubSpot — each maps to any object or custom field on the other side. | |
| 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. | Product Synced with incremental and full sync per the Stacksync docs. | Activities is specific to Eloqua and Product to HubSpot — 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. | Ticket Synced with incremental and full sync per the Stacksync docs. | Campaigns is specific to Eloqua and Ticket to HubSpot — 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.
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 HubSpot through its API, with automatic retries and rate-limit backoff.
DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.
DeliveryEach detected change is written to Eloqua through its API, with automatic retries and rate-limit backoff.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Eloqua–HubSpot connection.
Changes in Eloqua or HubSpot instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Eloqua or HubSpot data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Eloqua or HubSpot record.
Track your Eloqua ⇄ HubSpot sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Eloqua and HubSpot.
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 Eloqua and HubSpot 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 Eloqua and HubSpot 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 Eloqua and HubSpot: authenticate both systems, choose the objects to sync (such as Eloqua's Contacts and Contact Lists and Segments), map fields visually, and changes propagate both ways in milliseconds — no code required.
Eloqua: Bulk API 2.0 (contacts, accounts, custom data objects, activities) plus Application REST API (campaigns, emails, forms, lists). Authentication: OAuth 2.0 (Authorization Code or Resource Owner Password Credentials grant; Client Credentials not supported) or HTTP Basic Auth with siteName + username + password; the instance base URL must first be discovered via the login.eloqua.com/id endpoint. HubSpot: REST API (CRM v3). Authentication: OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields. Stacksync manages authentication, retries, and rate limits on both sides.
HubSpot: CDC Boost requires manually creating rollup calculation properties in HubSpot per association table (the unlabeled _label_none rollup is mandatory) and a sync restart to activate. Eloqua: Activity data (opens, clicks, form submits, bounces, page views) is export-only, so engagement history is read out of Eloqua but not written back. Stacksync's field mapping accounts for these differences between Eloqua and HubSpot 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 Eloqua and HubSpot records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Eloqua and HubSpot connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Eloqua–HubSpot integration in-house.
Yes — Stacksync ships production-grade connectors for both Eloqua and HubSpot. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
