Oracle Eloqua API
Oracle Eloqua is an enterprise B2B marketing automation platform that provides REST APIs for managing contacts, campaigns, email sends, lead scoring, and multi-channel marketing orchestration.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth 2.0 support is good but scopes are coarse-grained (role-based only). Basic auth option with username/password is a security risk if used in production. TLS enforced on all endpoints.
⚡ Reliability
Best When
Best when your organization already runs Oracle Eloqua as its marketing automation platform and needs programmatic integration with CRM, data warehouse, or custom business applications.
Avoid When
Avoid when you need a lightweight or self-serve marketing API — Eloqua requires an enterprise contract and significant onboarding investment.
Use Cases
- • Sync CRM contacts into Eloqua as prospects and update contact field values programmatically
- • Trigger campaign activations or email sends based on external events from other business systems
- • Pull campaign performance metrics and email engagement statistics into a unified analytics dashboard
- • Create and update custom data objects to enrich lead records with external data sources
- • Automate lead scoring updates by pushing behavioral signals from external apps into Eloqua
Not For
- • Transactional email delivery at high volume — use a dedicated transactional ESP instead
- • B2C marketing or consumer-scale contact databases with millions of unmanaged records
- • Teams without an existing Oracle Eloqua license — no self-serve or free tier available
Interface
Authentication
Supports OAuth 2.0 authorization code flow for production integrations and HTTP Basic auth for development. OAuth is recommended; Basic auth uses Eloqua site name prefix in username (sitename\\username format). No fine-grained scopes — access level is determined by the Eloqua user role assigned to the API user.
Pricing
No self-serve pricing or free trial. Access requires an Oracle Eloqua subscription and provisioning by Oracle.
Agent Metadata
Known Gotchas
- ⚠ Base URL is instance-specific and must be retrieved via a login endpoint first — hardcoding will fail across environments
- ⚠ Bulk API and REST API are separate interfaces with different endpoints and data models for the same objects
- ⚠ Daily API call quotas reset at midnight UTC and are shared across all integrations on the Eloqua instance
- ⚠ Contact deduplication is by email address by default, but custom deduplication keys can be set — agents must know which is active
- ⚠ Async Bulk API jobs require polling for completion status before results are available — no push notification when done
