Platform Events are part of Salesforce's event-driven architecture. When using Flows to subscribe to Platform Events, it’s important to understand how event listeners are tracked and how Flows interact with those events.

B. Correct — The Subscriptions related list on a Platform Event's detail page lists flows, Apex triggers, and processes subscribed to the event.

Incorrect Options:

A. Salesforce does not automatically prevent infinite loops; developers must design safeguards.

C. If a package with active event subscriptions is uninstalled, it can break functionality unless cleaned up.

D. You cannot query Platform Event messages using SOQL; events are ephemeral and processed in real-time.

Reference Extracts from Salesforce Process Automation Study Guide:

“Use the Subscriptions related list to view flows, triggers, and other automation tools listening to a Platform Event.”

“Platform Event messages are not stored in the database and cannot be queried via SOQL.”
