Which type of flow is triggered by a platform event message?

The type of flow that is specifically designed to be triggered by a platform event message is the Platform Event-triggered flow. This flow listens for platform events and initiates automatically when a new event message is published.

Platform events are part of Salesforce’s event-driven architecture, allowing you to define custom notifications and events that can be delivered in real time. When a platform event occurs, any associated flows or processes that are set up to respond to those events begin to execute, enabling immediate processing of the event's information and facilitating seamless communication between different components or systems.

Other flow types, such as record-triggered flows, are initiated by changes in record data within Salesforce, while schedule-triggered flows operate based on predefined time schedules. Autolaunched flows run in the background and do not interact with a user interface or require user input but are not specifically tied to platform event messages. Hence, each of these flows serves different use cases, reinforcing the unique purpose and functionality of Platform Event-triggered flows in the Salesforce ecosystem.
