Did ADK not have api that contain user input information?

[NBestsuNgan]

/apps/{app_name}/users/{user_id}/sessions/{session_id} from this link it only contain agent response data but if we can have user message too, it will be more easy to do human in the loops in my opinion or anyone else can do human in the loops in adk web now?

The session history can contain both user messages and agent responses. The Runner appends each new user message as an event with author="user".

After the run, fetch the session and inspect all of its events:

session = await session_service.get_session(
    app_name=app_name,
    user_id=user_id,
    session_id=session_id,
)
if session is not None:
    for event in session.events:
        if event.content is not None:
            print(event.author, event.content)

The /apps/{app_name}/users/{user_id}/sessions/{session_id} endpoint returns that session. The live run_async()/SSE output need not echo the input message back, even though the session stores it.

If the fetched history contains only agent replies, check that the message was submitted through the Runner using new_message, and that you retrieve the same app, user, and session ID afterward. Send the next user reply through that same session. Submitting user messages this way stores them alongside the replies.
