Why teams connect Crustdata and Eloqua
Flow Crustdata data into Eloqua in real time — no exports, no schedulers, no custom scripts.
Crustdata is a read-only source: Stacksync reads its data in real time and delivers it into Eloqua, so Eloqua always reflects the current state of Crustdata — without exports, scripts, or schedulers.
Crustdata 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.
Common use cases
- 01 Stream screener results into a warehouse to maintain a living TAM and target-account universe.
- 02 Append enrichment at lead-capture time so new records arrive scored and routable.
- 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
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 Crustdata, 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.
Segments and audiences follow the CRM
Where Eloqua builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Crustdata, so who receives a campaign reflects current pipeline reality instead of a stale export.
What you can sync between Crustdata 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.
| Crustdata objects | Eloqua objects | How this pairing syncs | |
|---|---|---|---|
| Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. | Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. | Tech Stack is specific to Crustdata and Emails to Eloqua — each maps to any object or custom field on the other side. | |
| Screener Results Saved company searches with filter criteria; read on a schedule so target-account lists in the CRM refresh as companies enter the criteria. | 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. | Screener Results is specific to Crustdata and Forms and Form Submits to Eloqua — each maps to any object or custom field on the other side. | |
| Enrichment Responses Real-time enrichment lookups keyed by domain or profile URL; read to append fresh firmographic and contact data at form-fill or record-creation time. | 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. | Enrichment Responses is specific to Crustdata and Contact Lists and Segments to Eloqua — each maps to any object or custom field on the other side. | |
| Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. | 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. | Companies is specific to Crustdata and Contacts to Eloqua — each maps to any object or custom field on the other side. | |
| People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. | 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. | People is specific to Crustdata and Accounts to Eloqua — each maps to any object or custom field on the other side. | |
| Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. | 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. | Headcount and Growth Metrics is specific to Crustdata and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side. |
How changes propagate between Crustdata 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.
Crustdata Eloqua Interval-based propagation
DetectionStacksync polls Crustdata for changes on an incremental schedule, reading only records changed since the previous pass. Pull-based: real-time enrichment endpoints for on-demand lookups plus periodic re-pulls of screeners and datasets.
DeliveryEach detected change is written to Eloqua through its API, with automatic retries and rate-limit backoff.
Eloqua Crustdata 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.
DeliveryCrustdata does not accept inbound record writes, so this direction carries requests rather than records: Crustdata's output flows back as field updates on the originating Eloqua records.
Rate-limit considerations
- Crustdata: Requests are metered by plan credits and per-minute rate limits; bulk dataset pulls are the efficient path for large refreshes rather than per-record enrichment calls.
- 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
Crustdata and Eloqua integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Crustdata and Eloqua — Crustdata is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Crustdata is a read-only source, so this integration runs one-way: Stacksync reads from Crustdata in real time and delivers into Eloqua. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for Crustdata and Eloqua: Where Eloqua captures engagement: activity lands on the record; Lead and lifecycle status agree; Segments and audiences follow the CRM. Opens, clicks, form fills, event attendance, or ad responses recorded in Eloqua post back to the contact or account in Crustdata, so reps see interest before they reach out.
-
Crustdata: REST API (JSON). Authentication: API token — Authorization: Token header issued per workspace. 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.
-
Crustdata: Crustdata is a data provider — the API is read-only, so syncs flow one way: out of Crustdata into your CRM, database, or warehouse. 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 Crustdata and Eloqua 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 Crustdata and Eloqua records are not retained after a sync operation.
