body Message Body Input The body of the comment.

Feed item and comment bodies have a 10,000 character limit. Because this limit can change, clients should make a describeSObjects() call on the FeedItem or FeedComment object and look at the length of the Body or CommentBody field to determine the maximum number of allowed characters.

To edit this property in a comment, make a PATCH request to /chatter/comments/commentId. Editing comments is supported in version 34.0 and later.
