Roblox API giving Invalid parameters response when they are correct

[OfficialMrDragonYT]

Hello,

I am trying to make an application (using python) that has a feature to display a Roblox user’s friends. I want to be able to use the alias that the user has set for their friends, though I cannot get the api to work.

I have tried to do this in Python, though it gives a 401 response of {"errors":[{"code":4,"message":"Invalid parameters.","userFacingMessage":"Something went wrong"}]}
The parameters seem to be as they are when the Roblox website sends a request.

This is my script:

import json

import requests

robloxSession = requests.Session()

robloxSession.cookies[".ROBLOSECURITY"] = "_|WARNING:-DO-NOT-SHARE-THIS.--Sharing-this-will-allow-someone-to-log-in-as-you-and-to-steal-your-ROBUX-and-items.|<--token-->"

req = robloxSession.post(url="https://auth.roblox.com/v2/logout")

robloxSession.headers["Content-Type"] = "application/json"

robloxSession.headers["Referer"] = "https://www.roblox.com"

robloxSession.headers["X-CSRF-TOKEN"] = req.headers["X-CSRF-Token"]

d = {"targetUserIds":[

# user ids of friends

]}

j = json.dumps(d)

req2 = robloxSession.post(url="https://contacts.roblox.com/v1/user/get-tags", json=j)

print(req2.content)

What’s wrong with this? Can somebody help please?
(also if this is the wrong category, i did not know which one to do sorry)

Have you tested your query on the docs page:
https://contacts.roblox.com/docs/index.html
I’d recommend ensuring your query works there

[OfficialMrDragonYT]

Yeah, i’ve tried it on there. It works there, but it does not work for me.

Not exactly sure why this is, but it works for me if I don’t json encode the payload.

[OfficialMrDragonYT]

Like this?

d = {"targetUserIds":[
    114942345
]}

req2 = robloxSession.post(url="https://contacts.roblox.com/v1/user/get-tags", data=d)

If so, it still doesn’t work for me

[stef0206 (Stef)]

I still passed the data into the json parameter despite not encoding it, so like this:

d = {"targetUserIds":[
    114942345
]}

req2 = robloxSession.post(url="https://contacts.roblox.com/v1/user/get-tags", json=d)

It worked! Thank you so much! <3
