Why teams connect Eloqua and Linnworks

Feed the real customer, order, and revenue records from Linnworks into Eloqua so campaigns run on who actually bought what, and let contact and consent changes flow back in real time.

Marketing runs on lists of people, but the list rarely knows which of those people are paying customers, what they ordered, or what they are worth. Linnworks holds exactly that: Open Orders, Processed Orders, Stock Items, Stock Levels that record who the customer is, what they bought, and what they owe. When the two are joined only by a periodic export, campaigns go out against stale audiences, existing customers get prospecting emails, high-value accounts look the same as cold leads, and a canceled order still counts toward a segment.

Stacksync syncs Open Orders, Processed Orders, Stock Items, Stock Levels in Linnworks with Contacts, Accounts, Custom Data Objects, Activities in Eloqua in real time, and where both sides accept writes, in both directions. Customer, order, and invoice data maps field by field onto the contacts, audiences, or accounts Eloqua works with, so segmentation and personalization run on current purchase history instead of a month-old snapshot. Contact details and consent changes that originate in Eloqua flow back onto the record in Linnworks.

The strongest bridge between the two is identity and purchase history, who the customer is and what they have bought, so that is where most of the value sits. Because the sync is field-level, each system keeps the attributes the other has no use for; only the shared records are held in agreement.

Common use cases

  • 01 Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
  • 02 Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
  • 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

Purchase history drives segmentation

Orders, invoices, and revenue totals from Linnworks land on the matching contact or account in Eloqua, so audiences are built from what customers actually bought and spent rather than from guesses.

Suppress or target existing customers

Because Linnworks knows who is already a paying customer, Eloqua can exclude them from acquisition campaigns or single them out for renewal and cross-sell.

One customer identity across both systems

A person or company's contact details corrected in either system update the other, so marketing and the back office stop maintaining separate versions of the same record.

What you can sync between Eloqua and Linnworks

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 Linnworks 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. Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. Contacts is specific to Eloqua and Open Orders to Linnworks — 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. Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Accounts is specific to Eloqua and Processed Orders to Linnworks — 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. Stock Items SKU records keep product data aligned with ERPs and PIMs. Custom Data Objects is specific to Eloqua and Stock Items to Linnworks — 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. Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. Activities is specific to Eloqua and Stock Levels to Linnworks — 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. Locations Warehouse and fulfillment location records scope stock data during mapping. Campaigns is specific to Eloqua and Locations to Linnworks — 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. Purchase Orders Replenishment POs sync with suppliers and accounting systems. Emails is specific to Eloqua and Purchase Orders to Linnworks — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Linnworks

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

Linnworks Eloqua Interval-based propagation

DetectionStacksync polls Linnworks for changes on an incremental schedule, reading only records changed since the previous pass. Polling on order and stock endpoints.

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.
  • Linnworks: Per-endpoint rate limits apply on the Linnworks API.
