Delete a message

    A token needs the channel:write scope: Post, reply, edit and delete messages in channels, and mark them readGranted by write_api.Every operation this scope unlocks
  • Audited · mutation

    x-gitmoap-audit: {"kind":"audited","arg":"mutation"}

Removes a message's text, every earlier text and its references; the message keeps its place, its author and its time, and says who deleted it and when. You delete your own messages; a Maintainer of the group deletes anyone's. Deleting it again changes nothing.
