Updated on Feb 6, 2026
The SmartPasteButton provides events to handle the AI request lifecycle, allowing you to show loading states, process responses, and handle errors.
Available Events
The component exposes three lifecycle events that allow you to handle the AI request process:
requestStart—Fires before sending the AI request. The event is preventable.requestEnd—Fires when the AI request completes, either successfully or with an error. The event is preventable.requestCancel—Fires when an ongoing Smart Paste request is cancelled by the user.
The following example demonstrates event handling for the SmartPasteButton. The demo displays each event and its arguments in the event log panel on the right side.
