They are used to trigger logic without requiring explicit user input or manual conditions. Event Tools ## Adding Event Tools to a Node Click the **+** button under the node to add a tool: * select **Node** * select an **Event Tool** from the list Event tools are attached to a node and executed automatically when the corresponding event occurs. *** ## Available Event Types * **On Start Event** — triggered when the interaction begins * **On Query Event** — triggered when the user sends a message * **On Answer Event** — triggered when the assistant responds * **On Finish Event** — triggered when the interaction ends * **On Schedule Event** — triggered at a scheduled time *** ## How It Works * The event occurs during the interaction * The corresponding event tool is triggered * The configured action is executed *** ## Usage Event tools are typically used for: * logging or analytics * triggering background processes * sending notifications * executing integrations * handling lifecycle events *** ## Best Practices * Use event tools only when automatic execution is required * Avoid adding unnecessary event triggers * Keep event logic simple and predictable * Test event behavior across different scenarios *** ## Notes * Event tools run automatically and do not require manual triggering * Multiple event tools can be attached to a single node * Proper configuration ensures correct timing and execution of actions
