## Comment

A comment on a file. Some resource methods (such as `comments.update`) require a `commentId`. Use the `comments.list` method to retrieve the ID for a comment in a file.

<div className="reference-table">
  | Field                                                           | Type                                    | Description                                                                                                                                                            |

  | `anchor`                                                        | `string`                                | A region of the document represented as a JSON string. For details on defining anchor properties, refer to Manage comments and replies.                                |
  | `quotedFileContent`                                             | [QuotedFileContent](#quotedfilecontent) | The file content to which the comment refers, typically within the anchor region. For a text file, for example, this would be the text at the location of the comment. |
</div>
