Why teams connect Eloqua and Intercom

Keep the people you sell to and the people you market to in one shared view: Intercom and Eloqua sync contacts, accounts, and engagement in real time, in both directions.

Intercom 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 Contacts, Companies, Conversations, Tickets in Intercom with Contact Lists and Segments, Contacts, Accounts, Custom Data Objects in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Intercom 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.

Common use cases

  • 01 Sync contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
  • 02 Push product usage events from an application database into Intercom to trigger onboarding and retention messages
  • 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

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

Where Eloqua captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Eloqua post back to the contact or account in Intercom, so reps see interest before they reach out.

Lead and lifecycle status agree

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.

What you can sync between Eloqua and Intercom

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 Intercom 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. Contacts A single contact model covers both users and leads, distinguished by a role attribute. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Data Events Behavioral events pushed in from product databases trigger messages and flows. Accounts is specific to Eloqua and Data Events to Intercom — 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. Custom Data Attributes Typed custom fields on contacts and companies hold synced billing and usage data. Custom Data Objects is specific to Eloqua and Custom Data Attributes to Intercom — 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. Tags Labels applied to contacts, companies, and conversations sync for routing and reporting. Activities is specific to Eloqua and Tags to Intercom — 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. Segments Saved audience definitions are readable for targeting parity across tools. Campaigns is specific to Eloqua and Segments to Intercom — 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. Admins & Teams Teammate records map conversation ownership to CRM users. Emails is specific to Eloqua and Admins & Teams to Intercom — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Intercom

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 Intercom 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 Intercom through its API, with automatic retries and rate-limit backoff.

Intercom Eloqua Sub-second propagation

DetectionIntercom notifies Stacksync of record changes through webhook events. Webhook topic subscriptions for contact, company, and conversation events, plus polling for backfill.

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.
  • Intercom: Subject to per-app rate limits on the Intercom API.
