This action allows you to obtain a short-lived embeddable URL for an item in order to render a temporary preview.

If you want to obtain long-lived embeddable links, use the createLink API instead.

Note: The preview action is currently only available on SharePoint and OneDrive for Business.

This API is available in the following national cloud deployments.
