Why teams connect Eloqua and Firebase
Give your team Eloqua's contacts, campaigns, and engagement in Firebase: query them with SQL, push audiences built from your own data back to Eloqua, and skip the marketing API.
Eloqua holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in Firebase, hard to get into campaigns without manual exports.
Stacksync mirrors Contact Lists and Segments, Contacts, Accounts, Custom Data Objects from Eloqua into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in Firebase, from usage, orders, or account status, sync back into Eloqua to drive campaigns and ads, with Eloqua kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.
Common use cases
- 01 Replace one-off Cloud Functions export code with managed, continuous sync.
- 02 Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
- 03 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.
- 04 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.
Common sync patterns
React to marketing changes as row changes
A new lead, form fill, or list change in Eloqua arrives as a row change in Firebase, so scoring, jobs, and notifications run in the tooling your team already uses.
Keep contact attributes consistent
Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.
Query Eloqua like a database
Contacts, leads, audiences, and campaign metrics from Eloqua live in Firebase as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.
What you can sync between Eloqua and Firebase
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 | Firebase 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. | Subcollections Nested collections under documents, typically flattened into related tables during sync. | Accounts is specific to Eloqua and Subcollections to Firebase — 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. | Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Custom Data Objects is specific to Eloqua and Realtime Database Nodes to Firebase — 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. | Authentication Users User accounts read into CRMs and warehouses for customer records. | Activities is specific to Eloqua and Authentication Users to Firebase — 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. | Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | Campaigns is specific to Eloqua and Cloud Storage Objects to Firebase — 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. | Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Emails is specific to Eloqua and Cloud Functions Triggers to Firebase — each maps to any object or custom field on the other side. | |
| 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. | Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Forms and Form Submits is specific to Eloqua and Firestore Collections to Firebase — each maps to any object or custom field on the other side. |
How changes propagate between Eloqua and Firebase
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 Firebase 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 Firebase through its API, with automatic retries and rate-limit backoff.
Firebase Eloqua Interval-based propagation
DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.
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.
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.

FAQ
Eloqua and Firebase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Eloqua and Firebase: authenticate both systems, choose the objects to sync (such as Eloqua's Accounts and Custom Data Objects), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes — Stacksync ships production-grade connectors for both Eloqua and Firebase. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Eloqua: Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax; no general-purpose record-change webhook. On Firebase: Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Firebase side: Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, plus custom fields where Firebase exposes them. On the Eloqua side: Contact Lists and Segments, Contacts, Accounts, Custom Data Objects. 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 Eloqua and Firebase: React to marketing changes as row changes; Keep contact attributes consistent; Query Eloqua like a database. A new lead, form fill, or list change in Eloqua arrives as a row change in Firebase, so scoring, jobs, and notifications run in the tooling your team already uses.
