Why teams connect Eloqua and Dynamics 365 Business Central

Feed the real customer, order, and revenue records from Dynamics 365 Business Central 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. Dynamics 365 Business Central holds exactly that: Customers, Vendors, Items, Sales Orders 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 Customers, Vendors, Items, Sales Orders in Dynamics 365 Business Central with Accounts, Custom Data Objects, Activities, Campaigns 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 Dynamics 365 Business Central.

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 vendor and purchase order data with procurement or AP automation tools.
  • 02 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.
  • 03 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.
  • 04 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.

Common sync patterns

Purchase history drives segmentation

Orders, invoices, and revenue totals from Dynamics 365 Business Central 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 Dynamics 365 Business Central 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 Dynamics 365 Business Central

How changes propagate between Eloqua and Dynamics 365 Business Central

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 Dynamics 365 Business Central 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 Dynamics 365 Business Central through its API, with automatic retries and rate-limit backoff.

Dynamics 365 Business Central Eloqua Sub-second propagation

DetectionDynamics 365 Business Central notifies Stacksync of record changes through webhook events. API webhooks (change notifications on subscribed entities) plus polling on lastModifiedDateTime.

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