Why teams connect Eloqua and Zoho CRM

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

Zoho 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 Lead, Contact, Account, Deal in Zoho CRM with Emails, Forms and Form Submits, Contact Lists and Segments, Contacts in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Zoho 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 Push warehouse-computed lead scores and product signals into Zoho CRM fields for rep prioritization.
  • 02 Keep Zoho CRM accounts aligned with an ERP or accounting system on customers and invoices.
  • 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

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 Zoho CRM, 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.

Segments and audiences follow the CRM

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

What you can sync between Eloqua and Zoho 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 Zoho 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. Contact Synced with incremental and full sync per the Stacksync docs. 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. Account Synced with incremental and full sync per the Stacksync docs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Deal Synced with incremental and full sync per the Stacksync docs. Contact Lists and Segments is specific to Eloqua and Deal to Zoho CRM — 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. Task Synced with incremental and full sync per the Stacksync docs. Custom Data Objects is specific to Eloqua and Task to Zoho CRM — 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. Meeting Synced with incremental and full sync per the Stacksync docs. Activities is specific to Eloqua and Meeting to Zoho CRM — 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. Call Synced with incremental and full sync per the Stacksync docs. Campaigns is specific to Eloqua and Call to Zoho CRM — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Zoho 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 Zoho 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 Zoho CRM through its API, with automatic retries and rate-limit backoff.

Zoho CRM Eloqua Sub-second propagation

DetectionZoho CRM notifies Stacksync of record changes through webhook events. Notification API (webhooks) on watched modules, with polling on Modified_Time.

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.
  • Zoho CRM: API credits are allocated per day and vary by edition.
