Prerequisite

Steps to Comments on PowerPoint Presentation with Java based API

  1. Create the SlidesApi object by setting the client ID and secret for adding comments
  2. Set the input presentation file name and the target slide index
  3. Define the slide comment and the relevant child comments collection
  4. Add the comments to the slide using the CreateComment method
  5. Fetch the comments count to confirm the addition of the comments
  6. Download the updated presentation file with new comments in it

These steps describe how to add comments in PowerPoint with Java RESTful Service. Set the input presentation file name and slide index, create the slide comment and sub-comments, and call the CreateComment() method to insert the comments by setting the input file name, target index, and comments. This call uploads the presentation, modifies it in the Cloud, and returns the collection of comments.
