Two-way sync
Changes in Eloqua or Outreach instantly reflect in both systems. No stale data, no manual imports.
Keep Eloqua and Outreach in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Outreach 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 Tasks, Opportunities, Users, Mailboxes in Outreach with Custom Data Objects, Activities, Campaigns, Emails in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Outreach 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.
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.
Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Outreach, so who receives a campaign reflects current pipeline reality instead of a stale export.
New leads or responders captured in Eloqua flow into Outreach assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.
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 | Outreach objects | How this pairing syncs | |
|---|---|---|---|
| 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 Companies grouping prospects, aligned with CRM account ownership | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| 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. | Calls Logged call records synced into engagement reporting | Forms and Form Submits is specific to Eloqua and Calls to Outreach — 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. | Tasks Rep action items mirrored between Outreach and the CRM | Contact Lists and Segments is specific to Eloqua and Tasks to Outreach — each maps to any object or custom field on the other side. | |
| 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. | Opportunities Deal records used to tie engagement to pipeline outcomes | Contacts is specific to Eloqua and Opportunities to Outreach — 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. | Users Seat holders used to resolve ownership on synced records | Custom Data Objects is specific to Eloqua and Users to Outreach — 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. | Mailboxes Connected sending accounts referenced when attributing outbound activity | Activities is specific to Eloqua and Mailboxes to Outreach — each maps to any object or custom field on the other side. |
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.
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 Outreach through its API, with automatic retries and rate-limit backoff.
DetectionOutreach notifies Stacksync of record changes through webhook events. Webhook subscriptions on resource create, update, and destroy events, plus polling.
DeliveryEach detected change is written to Eloqua through its API, with automatic retries and rate-limit backoff.

Yes. Stacksync provides a managed, real-time two-way integration between Eloqua and Outreach: authenticate both systems, choose the objects to sync (such as Eloqua's Accounts and Forms and Form Submits), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Eloqua and Outreach: Lead and lifecycle status agree; Segments and audiences follow the CRM; Where Eloqua generates leads: hand-off without re-keying. 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.
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. Outreach: REST API conforming to the JSON:API specification. Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
Outreach: Webhook subscriptions can be registered per resource for create, update, and destroy events, enabling near-real-time outbound sync. Eloqua: The Bulk API is an asynchronous staging workflow (define a sync definition, stage the data, sync, poll status, then retrieve) rather than an instantaneous call. Stacksync's field mapping accounts for these differences between Eloqua and Outreach 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 Outreach records are not retained after a sync operation.
