Why teams connect Affinity and Eloqua
Keep the people you sell to and the people you market to in one shared view: Affinity and Eloqua sync contacts, accounts, and engagement in real time, in both directions.
Affinity 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 List Entries, Persons, Organizations, Opportunities in Affinity with Forms and Form Submits, Contact Lists and Segments, Contacts, Accounts in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — Affinity 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 enrichment data computed elsewhere into Affinity field values on list entries.
- 02 Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
- 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
Segments and audiences follow the CRM
Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Affinity, so who receives a campaign reflects current pipeline reality instead of a stale export.
Where Eloqua generates leads: hand-off without re-keying
New leads or responders captured in Eloqua flow into Affinity assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.
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.
What you can sync between Affinity and Eloqua
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.
| Affinity objects | Eloqua objects | How this pairing syncs | |
|---|---|---|---|
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | 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. | Lists is specific to Affinity and Contact Lists and Segments to Eloqua — each maps to any object or custom field on the other side. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | 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. | List Entries is specific to Affinity and Contacts to Eloqua — each maps to any object or custom field on the other side. | |
| Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. | 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. | Persons is specific to Affinity and Accounts to Eloqua — each maps to any object or custom field on the other side. | |
| Organizations Company records matched to accounts in other systems by domain. | 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. | Organizations is specific to Affinity and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side. | |
| Opportunities Deal records tracked on lists and synced with pipeline reporting. | 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. | Opportunities is specific to Affinity and Activities to Eloqua — each maps to any object or custom field on the other side. | |
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. | Field Values is specific to Affinity and Campaigns to Eloqua — each maps to any object or custom field on the other side. |
How changes propagate between Affinity and Eloqua
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.
Affinity Eloqua Sub-second propagation
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
DeliveryEach detected change is written to Eloqua through its API, with automatic retries and rate-limit backoff.
Eloqua Affinity 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 Affinity through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Affinity: Subject to the platform's published API rate limits.
- 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.

FAQ
Affinity and Eloqua integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Affinity and Eloqua: authenticate both systems, choose the objects to sync (such as Affinity's Lists and List Entries), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Affinity side: List Entries, Persons, Organizations, Opportunities, plus custom fields where Affinity exposes them. On the Eloqua side: Forms and Form Submits, Contact Lists and Segments, Contacts, Accounts. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 Affinity and Eloqua: Segments and audiences follow the CRM; Where Eloqua generates leads: hand-off without re-keying; New and updated people stay in step. Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Affinity, so who receives a campaign reflects current pipeline reality instead of a stale export.
-
Affinity: REST API. Authentication: API key. 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. Stacksync manages authentication, retries, and rate limits on both sides.
-
Affinity: The data model centers on lists: a person, organization, or opportunity gains list-specific field values only through its list entry, so syncs must address both the entity and the entry. Eloqua: Activity data (opens, clicks, form submits, bounces, page views) is export-only, so engagement history is read out of Eloqua but not written back. Stacksync's field mapping accounts for these differences between Affinity and Eloqua without custom code.
