Class EventHandler (0.87.0)

public final class EventHandler extends GeneratedMessageV3 implements EventHandlerOrBuilder

An event handler specifies an event that can be handled during a session. When the specified event happens, the following actions are taken in order:

• If there is a trigger_fulfillment associated with the event, it will be called.
• If there is a target_page associated with the event, the session will transition into the specified page.
• If there is a target_flow associated with the event, the session will transition into the specified flow.
