It seems not have API to update private message Discourse API Docs I want to update a private message Could I use PUT topic to do it? Do you have any idea to update private message?

It seems blank here: https://meta.discourse.org/t/how-to-reverse-engineer-the-discourse-api/20576/32

כיצד לעדכן הודעה פרטית באמצעות API?

See How to reverse engineer the Discourse API. You’re on the right track, I think.
