# Create Discussion

> Creates a new discussion for the room. It requires at least one of the following permissions: `start-discussion` OR `start-discussion-other-user`, AND must be with the following setting enabled: `Discussion_enabled`.
The caller must be a member of the parent room. Apps are exempt from this check.

When **Force end-to-end encryption on private rooms** is enabled, you cannot create a discussion under an unencrypted private room. Make the parent room public or enable encryption on it before creating the discussion.
