for some reason it's not in REST API docs, but I used
users.get_all

I will then assume that there is a users.get_by_id as well? Fingers crossed! Thanks!
That said it would be great if they could add it to the documentation.

how do you know the ID?
I'm looking for this ...

in the UI I also see the display name, so I pulled all the users info, and match name to id

      {
        "id": "c2e33466fd9de1a0d2be8d803ad4fbed",
        "company": "d1bd92a3b039400cbafc60a7a5b1e52b",
        "name": "John Doe",
        "family_name": "John",
        "given_name": "Doe",
        "created": "2024-09-24T06:13:59.956000+00:00"
      }

this is how the object looks like

For my use case I poll tasks.get_all which returns an object that contains the user ID: None

correct, but!
I wrote a script that pulls tasks and limit for user
so I'm looking for users to knows their own id in advance

I'm afraid I don't really know, you could check out the user settings in the UI, top right corner on the user icon, maybe there is something there, but I didn't really find anything to that extent there myself.

yep that was my approached with no luck so far
hopefully someone from the ClearML dev team can give their input on this

Thanks again 🙌 , I managed to get the user's name like so

from clearml.backend_api.session.client import APIClient

client = APIClient()
task = client.tasks.get...
user_response = client.session.send_request(
    "users", "get_by_id", json={"user": task.user}
).json()
user_name = user_response["data"]["user"]["name"]
