Why teams connect Eloqua and Microsoft Dynamics 365 Sales
Keep the people you sell to and the people you market to in one shared view: Microsoft Dynamics 365 Sales and Eloqua sync contacts, accounts, and engagement in real time, in both directions.
Microsoft Dynamics 365 Sales 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 Quotes, Orders, Invoices, Activities in Microsoft Dynamics 365 Sales with Contacts, Accounts, Custom Data Objects, Activities in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Microsoft Dynamics 365 Sales 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 Run a two-way dual-run between Dynamics and another CRM during a migration.
- 02 Feed BI models with continuously updated CRM data instead of scheduled exports.
- 03 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.
- 04 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.
Common sync patterns
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.
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 Microsoft Dynamics 365 Sales, 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.
What you can sync between Eloqua and Microsoft Dynamics 365 Sales
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 | Microsoft Dynamics 365 Sales 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 accounts; synced with marketing and support systems. | 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. | Accounts Company records in Dataverse; the usual anchor for two-way sync with databases and ERPs. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| 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. | Activities Emails, calls, appointments, and tasks; read out for activity analytics. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| 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. | Leads Prospect records; written in from enrichment or web forms, read out on qualification. | Custom Data Objects is specific to Eloqua and Leads to Microsoft Dynamics 365 Sales — 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. | Opportunities Deal records with stages and estimated revenue; synced for pipeline reporting and close-triggered workflows. | Campaigns is specific to Eloqua and Opportunities to Microsoft Dynamics 365 Sales — 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. | Quotes Pricing proposals; often synced with CPQ or ERP pricing data. | Emails is specific to Eloqua and Quotes to Microsoft Dynamics 365 Sales — each maps to any object or custom field on the other side. |
How changes propagate between Eloqua and Microsoft Dynamics 365 Sales
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 Microsoft Dynamics 365 Sales 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 Microsoft Dynamics 365 Sales through its API, with automatic retries and rate-limit backoff.
Microsoft Dynamics 365 Sales Eloqua Sub-second propagation
DetectionMicrosoft Dynamics 365 Sales notifies Stacksync of record changes through webhook events. Dataverse change tracking with delta tokens, plus registered webhooks on table events.

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.
- Microsoft Dynamics 365 Sales: Requests are governed by Dataverse service protection limits evaluated per user and time window.

FAQ
Eloqua and Microsoft Dynamics 365 Sales integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Eloqua and Microsoft Dynamics 365 Sales: authenticate both systems, choose the objects to sync (such as Eloqua's Contacts and Accounts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Eloqua and Microsoft Dynamics 365 Sales: New and updated people stay in step; Where Eloqua captures engagement: activity lands on the record; Lead and lifecycle status agree. 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.

Eloqua: Bulk API 2.0 (contacts, accounts, custom data objects, activities) plus Application REST API (campaigns, emails, forms, lists). Authentication: OAuth 2.0 (Authorization Code or Resource Owner Password Credentials grant; Client Credentials not supported) or HTTP Basic Auth with siteName + username + password; the instance base URL must first be discovered via the login.eloqua.com/id endpoint. Microsoft Dynamics 365 Sales: Dataverse Web API (OData v4 REST). Authentication: OAuth 2.0 via Microsoft Entra ID. Stacksync manages authentication, retries, and rate limits on both sides.
-
Microsoft Dynamics 365 Sales: Alternate keys allow upserts against external identifiers, so integrations do not need to store Dataverse GUIDs to write reliably. Eloqua: Contact records are keyed on email address; imports upsert against email as the default match key, so records without a valid email cannot be matched. Stacksync's field mapping accounts for these differences between Eloqua and Microsoft Dynamics 365 Sales without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Eloqua and Microsoft Dynamics 365 Sales records are not retained after a sync operation.
