Redaction allows you to permanently remove attachments from an existing comment on a ticket. Once removed from a comment, the attachment is replaced with an empty "redacted.txt" file.
The redaction is permanent. It is not possible to undo redaction or see what was removed. Once a ticket is closed, redacting its attachments is no longer possible.
Also, if you want to redact an inline attachment, you can use the include_inline_images
parameter in the List Comments operation to obtain the inline attachment ID, and use it in the request URL.
