What Stacksync syncs in Eloqua.

These objects sync between Eloqua and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Eloqua exposes them.

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.
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.
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.
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.
Campaigns
Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting.
Emails
Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync.
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.
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.
API surface

How Stacksync connects to Eloqua.

The connector runs on Eloqua's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
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
Change detection
Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax; no general-purpose record-change webhook
Rate limits
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

Use cases

What teams run on the Eloqua connector.

Oracle Eloqua is the enterprise B2B marketing automation platform, owned by marketing operations and demand-generation teams inside large, often regulated organizations. It is the system of engagement for lead capture, nurture, scoring, and email: Contacts (keyed by email), Accounts, Custom Data Objects, campaign membership, and a rich Activity history of opens, clicks, form submits, and page views all live there. RevOps and data teams need that engagement data flowing out to the CRM and warehouse, and enriched or scored records flowing back in.

  1. Two-way sync Contacts between Eloqua and a Postgres or warehouse table, matched on email, so ops teams query and update marketing profiles in SQL while marketers keep working in Eloqua.

  2. Push new and updated Accounts and Contacts from Salesforce or an ERP into Eloqua for lead nurturing, matched on email and company.

  3. Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.

  4. Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.

  5. Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.

  6. Two-way sync of Eloqua Contacts with an operational Postgres database, matched on email, so downstream apps read and update marketing profiles in SQL while marketers keep working in Eloqua.

FAQ

Eloqua connector FAQ

What can I sync with the Eloqua connector?

Eloqua's core objects — Contacts, Accounts, Custom Data Objects, Activities and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Eloqua?

Via Bulk API 2.0 (contacts, accounts, custom data objects, activities) plus Application REST API (campaigns, emails, forms, lists), authenticated with 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. Changes are detected as follows — polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax; no general-purpose record-change webhook. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Eloqua connector two-way?

Yes. Changes made in Eloqua propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does an Eloqua integration take to set up?

Most Eloqua integrations go live in minutes: authenticate Eloqua and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Eloqua data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Eloqua data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
