Redaction allows you to permanently remove words, strings, or attachments from a ticket comment. In the `html_body` of the comment, wrap the content you want redacted in `<redact>` tags. Example: ```json { "html_body": "<div class=\"zd-comment\" dir=\"auto\">My ID number is <redact>847564</redact>!</div>", "ticket_id":100 } ``` The characters in the redact tag will be replaced by the ▇ symbol.
