It seems not have API to update private message https://docs.discourse.org/#operation/createTopicPostPM I want to update a private message Could I use PUT topic to do it? Do you have any idea to update private message?

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

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

请参阅如何逆向工程 Discourse API。我认为你走在正确的道路上。
