This code demonstrates how to remove slide from PPT with Java Low Code API. The DeleteSlide() method requires the uploaded presentation name and the slide index starting from 1 that you want to delete. The API response contains the list of remaining slides that are left in the uploaded presentation that you can display using the Href property.

This article has taught us to delete individual slides from a presentation. If you want to split slides from a presentation, refer to the article on Split Slides with Java REST API.
