Why teams connect Copper CRM and Eloqua

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

Copper CRM 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 Projects, Pipelines, Custom Field Definitions, People in Copper CRM with Custom Data Objects, Activities, Campaigns, Emails in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Copper CRM 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 Copper people and opportunities into a warehouse for pipeline reporting beyond Copper's native dashboards.
  • 02 Two-way sync between Copper and an accounting or invoicing system so won opportunities become customers and invoices.
  • 03 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.
  • 04 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.

Common sync patterns

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.

Segments and audiences follow the CRM

Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Copper CRM, so who receives a campaign reflects current pipeline reality instead of a stale export.

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

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

What you can sync between Copper CRM 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.

Copper CRM objects Eloqua objects How this pairing syncs
Activities Logged emails, calls, meetings, and notes attached to records. 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. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Pipelines Stage definitions that give opportunity records their stage context. 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. Pipelines is specific to Copper CRM and Contacts to Eloqua — each maps to any object or custom field on the other side.
Custom Field Definitions Org-defined fields whose definitions are fetched to build dynamic field mappings. 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 Field Definitions is specific to Copper CRM and Accounts to Eloqua — each maps to any object or custom field on the other side.
People Individual contact records, often created from Gmail interactions, and the main target of contact syncs. 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. People is specific to Copper CRM and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side.
Companies Organization records linked to people and opportunities. Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Companies is specific to Copper CRM and Campaigns to Eloqua — each maps to any object or custom field on the other side.
Leads Unqualified prospects kept separate from People until converted. Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Leads is specific to Copper CRM and Emails to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between Copper CRM 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.

Copper CRM Eloqua Sub-second propagation

DetectionCopper CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record create/update/delete events.

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

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

Rate-limit considerations

  • Copper CRM: Subject to the platform's API rate limits.
  • 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.
