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

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.

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

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.

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"]

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