Attach a UI interaction to a UI Builder page event so the interaction runs when a user performs an action on a component.

## Antes de Iniciar

You have already created a UI interaction that you want to trigger.

Role required: ui_builder_admin

## Por Que e Quando Desempenhar Esta Tarefa

UI interactions don't run on their own. To execute an interaction, you must attach it to an event that occurs on a page or component. UI interactions are triggered by page events, including events mapped from component
actions.

In this task, you configure a component event on a page to trigger an existing UI interaction.

## Procedimento

1. Navigate to AllNow Experience FrameworkUI Builder.
2. Open an experience to work in or create an experience by selecting CreateExperience.  
   For more information, see [Configure how users interact with your applications in UI Builder](https://servicenow-prod.fluidtopics.net/dUVGdKGQs6AbFNSw~vNKcQ "Learn what an experience is in UI Builder. Understand what an experience contains.").
3. Create or open a page within the experience.  
   For more information about how to create a page in UI Builder, see [Create a page in UI Builder](https://servicenow-prod.fluidtopics.net/SclXrv5libg5iBN91G7scQ "Create a page in UI Builder for a portal, workspace, or custom application so that you can build a web experience for your users.").
4. Select the component that should trigger the interaction.  
   If the page doesn't already include the component you want to use, add it to the page first. For more information about adding components to a page, see [Add and configure components](https://servicenow-prod.fluidtopics.net/cbYaV7wlkZDBulAnOqnPNA#add-components "Learn how to add components to your page in UI Builder. A page is built by adding components.").
5. In the component configuration panel, select the Events tab.  
   Figura 1. Events tab
6. Select Add handler.
7. Search for your UI interaction by name, or select the UI interactions pill to filter results.
8. Select the UI interaction that you want to trigger.  
   Nota:  
   If your interaction type is Form or List and the applicable controller isn't already on the page, it is added automatically. If multiple controllers exist on the page, you're prompted to choose which one feeds data to the interaction.

9. Select Add.
10. Select Save.
11. Select Preview, then perform the action that fires the configured event to verify the interaction runs.

## Resultado

When the specified page event occurs, the UI interaction runs and executes its configured actions.
