Why teams connect Clari and Eloqua

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

Clari 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 Forecast, Quota, Opportunities, Activity (Capture) in Clari with Contacts, Accounts, Custom Data Objects, Activities in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Clari 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 Enrich Clari Account records with firmographic or billing data points through the ingest API in incremental mode.
  • 02 Stream Audit Events into a reporting database to monitor forecast-submission changes and user activity for compliance.
  • 03 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.
  • 04 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.

Common sync patterns

Where Eloqua generates leads: hand-off without re-keying

New leads or responders captured in Eloqua flow into Clari assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

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 Clari, so reps see interest before they reach out.

What you can sync between Clari and Eloqua

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.

Clari objects Eloqua objects How this pairing syncs
Audit Events User edits and system events exported with filtering by actor, session, and date range; read-only feed for change tracking and compliance. Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Audit Events is specific to Clari and Campaigns to Eloqua — each maps to any object or custom field on the other side.
Forecast Exported per forecast tab and fiscal period via async jobs; includes submitted forecast calls, updates, manager adjustments, and CRM totals. Read-only. Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Forecast is specific to Clari and Emails to Eloqua — each maps to any object or custom field on the other side.
Quota Quota and quota-history values exported alongside forecast data, scoped by fiscal quarter; read-only, useful for warehouse attainment reporting. 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. Quota is specific to Clari and Forms and Form Submits to Eloqua — each maps to any object or custom field on the other side.
Opportunities Retrieved synchronously by ID from GET /opportunity (up to 100 IDs per call) with Clari CRM scoring and field-change history; read-only, mirroring the CRM opportunity Clari sits on. 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. Opportunities is specific to Clari and Contact Lists and Segments to Eloqua — each maps to any object or custom field on the other side.
Activity (Capture) Meetings, emails, and attachments captured by Clari and mapped to accounts and opportunities; exported read-only via async activity jobs. 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. Activity (Capture) is specific to Clari and Contacts to Eloqua — each maps to any object or custom field on the other side.
Account field extensions External data points written onto Account records through the ingest API in initial or incremental mode; requires an apikey plus a partnerkey. 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. Account field extensions is specific to Clari and Accounts to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between Clari and Eloqua

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.

Clari Eloqua Interval-based propagation

DetectionStacksync polls Clari for changes on an incremental schedule, reading only records changed since the previous pass. Polling — reads run as asynchronous export jobs (submit export, poll job status, download results).

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

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

Rate-limit considerations

  • Clari: Max 3 concurrent exports and roughly 1000 exports per rolling 30-day org window; ingestion capped at 100 requests/sec per API token.
  • 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.
