Customizations on Preview Pages

Kintone Apps have a preview feature , where the App Administrator can access a preview environment of the App before deploying it. Although JavaScript customizations can run in these environments, any Kintone REST APIs used will affect the deployed environment. For example, a JavaScript code can display a button which will add a new record using the Add Record API. Accessing the preview pages and clicking this button will not create a new record in the App of the preview pages. A new record will be created in the deployed environment instead.
