Choosing the reporting source by audience and license: an error-log object for business users, the free API Total Usage log downloaded daily, the API Request Limit per Month entitlement, the Event Log File Browser and Event Monitoring Analytics app, external tools fed by CreatedDate with duplicate handling, and Real-Time Event Monitoring's ApiEvent.

- Certification: Salesforce Integration Architect
- Exam section: Maintain Integration
- Study guide: https://www.certifyforce.com/study-guide/integration-architect

**Official exam objective:**

> Given a use case, identify reporting needs for integration monitoring.

## What the exam expects

- Choose the reporting source from the audience: business users, finance and contract owners, administrators, or an external operations team.
- Report on API usage per connected app and user without the Event Monitoring add-on, and keep history beyond one day.
- Find 30-day API totals for contract decisions, and tell them apart from daily usage views.
- Pick between the Event Log File Browser, the Event Monitoring Analytics app and an external tool, and design a loader that misses no files and tolerates duplicates.
- Use Real-Time Event Monitoring's `ApiEvent` for query-level reporting captured as it happens.

Key terms: **API Total Usage** (free event log of inbound SOAP, REST and Bulk API requests), **latent log file** (a file delivered late, possibly repeating events), **Event Log File Browser** (Setup page to explore and download log files), **Event Monitoring Analytics app** (CRM Analytics app with prebuilt dashboards), **ApiEvent** (stored Real-Time Event Monitoring record of API queries).
