Why teams connect AWS S3 and Eloqua

Put modeled data to work and measure what it drives: AWS S3 and Eloqua keep contacts, audiences, and campaign results in step in real time, in both directions.

AWS S3 is where your team models customers, product usage, and revenue into trusted tables; Eloqua runs the campaigns, audiences, and messages that reach those people. The two overlap wherever the same person, account, or segment matters to both, and when the bridge between them is a nightly export or a hand-built list, marketing targets stale data while analytics never sees what the campaign returned.

Stacksync syncs Multipart Uploads, Buckets, Objects, Prefixes in AWS S3 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 — a computed score or segment can flow out to Eloqua while sends, opens, and conversions flow back to AWS S3 — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Stage bulk loads for warehouses that ingest from object storage.
  • 02 Archive change history from ongoing syncs as timestamped files for audit and replay.
  • 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

Enrich records with warehouse context

Product-usage counts, plan tier, region, or account owner computed in AWS S3 appear on the matching record in Eloqua, so targeting, routing, and personalization use up-to-date context.

Activate a modeled audience

A segment or score built in AWS S3 — high-intent accounts, churn risk, a lifetime-value tier — lands as an audience or contact field in Eloqua, so campaigns target the people your data actually points to instead of a static export.

Keep the contact and audience list current

New and updated contacts, leads, or audience members flow between AWS S3 and Eloqua, so the marketing audience reflects the people in your warehouse and corrections propagate instead of the two sides drifting apart.

What you can sync between AWS S3 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.

AWS S3 objects Eloqua objects How this pairing syncs
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. 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. Objects is specific to AWS S3 and Contacts to Eloqua — each maps to any object or custom field on the other side.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. 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. Prefixes is specific to AWS S3 and Accounts to Eloqua — each maps to any object or custom field on the other side.
Object Metadata System and user-defined metadata read alongside object contents. 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. Object Metadata is specific to AWS S3 and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. 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. Object Versions is specific to AWS S3 and Activities to Eloqua — each maps to any object or custom field on the other side.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Event Notifications is specific to AWS S3 and Campaigns to Eloqua — each maps to any object or custom field on the other side.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Access Points is specific to AWS S3 and Emails to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 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.

AWS S3 Eloqua Sub-second propagation

DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.

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

Eloqua AWS S3 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 AWS S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
  • 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.
