The RTM API only supports posting simple messages formatted using our default message formatting mode. It does not support attachments or other message formatting modes. To post a more complex message as a user clients can call the chat.postMessage Web API method with as_user set to true.

Put thread requests as thread Fixed in 5b45dde

1. Recognize threaded messages by looking for a thread_ts attribute: any message with a thread_ts attribute is part of a thread!
2. Identify replies by noting when a threaded message's ts and thread_ts values differ. If they're equal, you're dealing with a parent.
3. Attach your messages to a thread by specifying another message's ts value as your reply's thread_ts.
4. When responding to a message that's part of a thread, you should keep your responses in the thread.
5. When responding to a non-threaded message, consider creating a thread by replying to the message inciting your response.
