This runs in the Acrobat app - there is no separate API for this task.
In Adobe Acrobat, 'comments' is a general term for feedback added to a document. 'Annotations' is a more technical term for the specific tools used to create these comments, such as sticky notes, highlights, and drawing markups. So, an annotation is a type of comment, and comments are the overall feedback you provide using these tools.
No, drawing markups and other comments are not permanent by default. They are added as a separate layer on top of your PDF. This means you can easily edit, hide, or remove them later. If you want to make them permanent, you would need to 'flatten' the PDF, which merges the comment layer with the document content. Otherwise, they remain editable data.
You should sanitize your PDF to protect your privacy and prevent accidental information leaks. Comments and markups contain review notes that might not be suitable for the final audience. Sanitizing removes all these review notes, ensuring that only the final, clean document is shared. This is important to avoid sharing internal feedback or sensitive information that was part of the review process.
