# changeThreadDiscussionStatus

> Move a discussion between OPEN and RESOLVED. Resolving records the resolution timestamp and
settles agentStatus; reopening clears the timestamp and leaves agentStatus alone, because
reopening does not mean an agent has picked the work up again. Doing nothing when the discussion
is already in that status. Callable by a person, or by the agent a custom-agent discussion is
bound to, so an agent can mirror its own thread status back into Plain.
