Any message at the bottom of the app?

It shows this JSON. If that destination in the data body is the same as Post payload, then I think it's supposed to something other than null (I've looked up LCU help and find destination required.

{
    "body" : {
        "body" : null,
        "clientId" : "nil",
        "correlationId" : "1041991786-348",
        "destination" : null,
        "headers" : {},
        "messageId" : "C0E83D71-F0D0-4578-9FBD-0B037F98A04C",
        "timeToLive" : 0.0,
        "timestamp" : 1692451150479.0
    },
    "typeName" : "flex.messaging.messages.AcknowledgeMessage"
}

"PostLolLoginV1SessionInvoke": {
    "arguments": [
        {
            "destination": {
                "type": "string"
            }
        },
        {
            "method": {
                "type": "string"
            }
        },
        {
            "args": {
                "type": "vector of object"
            }
        }

}

I've tried myself by posting through the same url and arguments as in your code. Here's what I got (though destination is given, it still says that destination is required)

To me works correctly as it is now

import requests as rq
import json
import urllib3
urllib3.disable_warnings()
headers = {"Authorization": "Basic ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"}
baseUrl = "https://127.0.0.1:9955"
print(json.dumps(rq.post(f'{baseUrl}/lol-login/v1/session/invoke?destination=lcdsServiceProxy&method=call&args=["", "teambuilder-draft", "quitV2", ""]', "", verify=False, headers=headers).json(), indent=4))

OK I think there's something wrong on my end and I don't know what it is. I use the same code as you did and still doesn't work. Is there anything known to cause this issue?

[BennyExtreme]

Keep in mind that in custom it does not work. Btw, what server are you on?

oh... rlly didn't know that I play on Taiwanese server

and one more thing, how can I get that header Basic Auth key

[BennyExtreme]

You can get it through KBotExt in the "Custom" tab, clicking on "Custom Port/Header" and then "LCU". In the headers there will also be the "Authorization" header.

Otherwise, there are 2 other methods:

• Lockfile: Usually you can find the file in the league installation directory, like C:\Riot Games\League of Legends\lockfile the format of this file is the following <Process Name>:<Process ID>:<Port>:<Password>:<Protocol> The username is always riot
• Launch arguments: Open a terminal and write the following command wmic PROCESS WHERE name='LeagueClientUx.exe' GET commandline. After doing that you can find the info that you need in the args, like:
  • --app-port=<port> is the port, so the url is https://127.0.0.1:<port>
  • --remoting-auth-token=<password> is the password
  • The username is always riot

Once you have this information you can compose your Authorization header:

• Create a string with "Basic "
• Encode in base64 the credentials in this format riot:<password>
• Append it to the auth string

  In Python you can use

  import base64
  
  password = "<password>"
  
  print("Basic " + base64.b64encode((f"riot:{password}").encode()).decode())

Getting credentials for the Riot Client works the exact same way:

• KBotExt: "Custom" tab, clicking on "Custom Port/Header" and then "Riot". In the headers there will also be the "Authorization" header.
• Lockfile: Usually you can find the file in the localappdata Riot Games directory, like %LOCALAPPDATA%\Riot Games\Riot Client\Config\lockfile the format of this file is the following <Process Name>:<Process ID>:<Port>:<Password>:<Protocol> The username is always riot

  PS: For the path in Python you can use

  os.path.join(os.getenv("LOCALAPPDATA"), R"Riot Games\Riot Client\Config\lockfile")

• Launch arguments: Open a terminal and write the following command wmic PROCESS WHERE name='LeagueClientUx.exe' GET commandline. After doing that you can find the info that you need in the args, like:
  • --riotclient-app-port=<port> is the port, so the url is https://127.0.0.1:<port>
  • --riotclient-auth-token=<password> is the password
  • The username is always riot
