Why teams connect Eloqua and Vtiger CRM

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

Vtiger 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 Sales Orders, Invoices, Campaigns, Contacts in Vtiger CRM 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 — Vtiger 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 Replicate pipeline data to a warehouse for RevOps reporting.
  • 02 Mirror Leads and Campaigns to an email platform to keep marketing lists current.
  • 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

Segments and audiences follow the CRM

Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Vtiger 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 Vtiger CRM 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.

What you can sync between Eloqua and Vtiger CRM

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 Vtiger CRM 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 Person records linked to organizations; a core target for two-way contact syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Campaigns Marketing campaign records tied to leads and contacts. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Invoices Billing documents pushed into accounting software. Emails is specific to Eloqua and Invoices to Vtiger CRM — each maps to any object or custom field on the other side.
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. Organizations Company and account records. Forms and Form Submits is specific to Eloqua and Organizations to Vtiger CRM — each maps to any object or custom field on the other side.
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. Leads Unqualified prospects that convert into contacts, organizations, and opportunities. Contact Lists and Segments is specific to Eloqua and Leads to Vtiger CRM — 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. Opportunities Deal records, historically the Potentials module, synced for pipeline reporting. Accounts is specific to Eloqua and Opportunities to Vtiger CRM — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Vtiger CRM

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

Vtiger CRM Eloqua Sub-second propagation

DetectionVtiger CRM notifies Stacksync of record changes through webhook events. Polling on record modified timestamps.

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.
  • Vtiger CRM: Subject to the platform's API rate limits, which vary by edition.
