Python Rest-API script problem

Helllo.
I’m trying to add some new labels to some existing hosts with the following python code but can’t get it to work. What part am I missing?

The Json host_config from “https://admin.example.com/site/check_mk/api/1.0/objects/host_config/server1.example.com” looks like this:

"63a23228b9589b9c29c2241339e100f3530761c17c7821b1caefc5ff0c"
{'domainType': 'host_config',
 'extensions': {'attributes': {'labels': {'Test1': 'test1', 'Test2': 'test2'},
                               'meta_data': {'created_at': '2022-12-01T09:05:11+00:00',
                                             'created_by': 'user',
                                             'updated_at': '2023-02-09T22:35:58.956734+00:00'}},
                'cluster_nodes': None,
                'effective_attributes': None,
                'folder': '/admin_folder/customers/customer1/linux-servers/linux',
                'is_cluster': False,
                'is_offline': False},
 'id': 'server1.example.com',

And here is the python script I’m using. But for some reason it’s not adding any new labels or updating the old ones:

#!/usr/bin/env python5
import json
import urllib.request
import pprint


HOST_NAME = "https://admin.example.com"
SITE_NAME = "site"
API_URL = f"https://{HOST_NAME}/{SITE_NAME}/check_mk/api/1.0"

USERNAME = "user"
PASSWORD = "pass"

HOSTNAME = "server1.example.com"

query_string = urllib.parse.urlencode({
})

request = urllib.request.Request(
    f"{API_URL}/objects/host_config/{HOSTNAME}?{query_string}",
    method="GET",
    headers={
        "Authorization": f"Bearer {USERNAME} {PASSWORD}",
        "Accept": "application/json",
   },
)
response = urllib.request.urlopen(request)
if response.status == 200:
    etag = str(response.headers["ETag"])
    print(etag)


f"{API_URL}/objects/host_config/{HOSTNAME}",
method="PUT",   
headers={
        "Authorization": f"Bearer {USERNAME} {PASSWORD}",
        "Accept": "application/json",
        "If-Match": etag,  # (required) The value of the, to be modified, object's ETag header.
        "Content-Type": 'application/json',  # (required) A header specifying which type of content is in the request/response body.
    },
data=json.dumps({
    "update_attributes": {
        "labels":{
            "Test2": "test123",
            "Test3": "test3"
            }
        }
        

}).encode('utf-8'),


response = urllib.request.urlopen(request)
if response.status == 200:
    pprint.pprint(json.loads(response.read()))
elif response.status == 204:
    print("Done")
else:
    raise RuntimeError(response.read())

Thank you.

without seeing the error it’s hard to understand what you are doing wrong unless reading all your code…

Yes sorry, there is no error when running the code. It just spits out the json from the host_config with:

if response.status == 200:
    pprint.pprint(json.loads(response.read()))

But it doesn’t update or add the new labels.

I guess you do activate changes as well after API post? Or do you look in WATO?
Should you expect a 204?

Please note that you need to add your previous labels as well, checkmk do not have an “add” function.
