Use UI Builder (UIB) APIs in UIB client applications.
* **[api - UI Builder](https://servicenow-prod.fluidtopics.net/0iS74DaTo1jnkN1GBpOiXQ#apiAPI)**   
  The api API provides methods that you can use when developing client scripts in the UI Builder.
* **[helpers - UI Builder](https://servicenow-prod.fluidtopics.net/m6uGLGF8K8fgLD0zGRdy9w#helpersAPI)**   
  The helpers API provides general functionality that is common across page scripts, eliminating the need to write scripts for simple functionality such as opening and closing a modal.
