Roblox group API issues *Python*

Help and Feedback Scripting Support
#1

Howdy. I’m having some trouble with roblox’s group API - specifically, to change rank.
I’m using the /v1/groups/{groupId}/users/{userId} API, which requires me to provide a roleId. However, when I send the request (using the patch method), I get a status code 400, reason code 2, which states
the roleset is not found. (I’ve already supplied my roblosecurity and x-csrf token, that’s not the issue.)
However, I know for a fact that the roleId is correct - I’m passing in 249 (as an int), which corresponds to the rank “Corporal” in my group.

                            rankdict = {"Commander":255,"Deputy Commander":254,"Board of Directors":253,"Captain":252,"Lieutenant":251,"Sergeant":250,"Corporal":249,"Senior Public Safety Officer":248,"Public Safety Officer":247,"Suspended":246}

                            def rbx_request(method, url, **kwargs):
                                request = self.session.request(method, url, **kwargs)
                                method = method.lower()
                                if (method == "post") or (method == "put") or (method == "patch") or (method == "delete"):
                                    if "X-CSRF-TOKEN" in request.headers:
                                        self.session.headers["X-CSRF-TOKEN"] = request.headers["X-CSRF-TOKEN"]
                                        if request.status_code == 403:  # Request failed, send it again
                                            request = self.session.request(method, url, **kwargs)
                                return request

                            role_id = int(rankdict[(rank.content).capitalize()])
                            req = rbx_request("PATCH",f"https://groups.roblox.com/v1/groups/11062645/users/{self.userId}", params={"roleId":role_id, "groupId":11062645, "userId":self.userId})

Any help is appreciated.
tl;dr - getting status code 400 reason code 2 on roblox change group rank API call, have no clue why because the role id I’m passing to roblox is valid

edit: here is the API to save you some trouble
https://groups.roblox.com/docs#!/Membership/patch_v1_groups_groupId_users_userId

This

params={"roleId":role_id, "groupId":11062645, "userId":self.userId}

should not include the groupId and userId since those are only meant to be provided in the path.

The following would be correct:

params={"roleId": role_id}

Changed that. Still seeing status code 400 and the rank isn’t changing in the group.
I tried using the roleSetIds as well, which didn’t work either

#4

I’m not entirely sure since I no longer use Python a lot but doesn’t **kwargs automatically wrap everything in a table? If so, you should change this line

request = self.session.request(method, url, **kwargs)

to

request = self.session.request(method, url, kwargs["params"])

Forgot to reply @ibm03

#5

Tried doing that, still didn’t work. I changed it from kwargs to just a param arg and that didn’t work either.
I honestly have no clue at this point, I’m running out of ideas haha

rankdict = {"Commander":255,"Deputy Commander":254,"Board of Directors":253,"Captain":252,"Lieutenant":251,"Sergeant":250,"Corporal":249,"Senior Public Safety Officer":248,"Public Safety Officer":247,"Suspended":246}
	
def rbx_request(method, url, **kwargs):
	request = self.session.request(method, url, kwargs['params'])
	method = method.lower()
	if (method == "post") or (method == "put") or (method == "patch") or (method == "delete"):
		if "X-CSRF-TOKEN" in request.headers:
			self.session.headers["X-CSRF-TOKEN"] = request.headers["X-CSRF-TOKEN"]
			if request.status_code == 403:  # Request failed, send it again
				request = self.session.request(method, url, kwargs['params'])
	return request

role_id = int(rankdict[(rank.content).capitalize()])
req = rbx_request("PATCH",f"https://groups.roblox.com/v1/groups/11062645/users/{self.userId}", params={"roleId":role_id})

This code should work fine. If you’re still having problems, then perhaps it’s some other bit of code.

#7

In that case, I’m not entirely sure. That’s all the code related to that API call, and it’s still not working after changes. There’s really no more information that I can provide other than what’s in the original post. Perhaps somebody else can think of something

#8

I updated the post again, I missed the first request and changed the 403 code detector to detect any 4xx error.

#9

Hello! I wrote the original tutorial that this rbx_request function came from; it was designed to only send an extra request when a 403 code occurred as that is the only response code that requires sending duplicate requests. Adding this change could cause duplicate requests to be sent when they aren’t required - as such you should not modify the function in this way.

The value you’re supplying as roleId is not a role id. It’s a rank. You need to send a request to https://groups.roblox.com/v1/groups/{groupId}/roles to obtain a roleId.

solved (thanks @local_ip for helping me in his server!)
because the request method is PATCH, I need to use “json”, not “params” when passing the role_id.

ie:

req = rbx_request("PATCH",f"https://groups.roblox.com/v1/groups/GROUPID/users/{self.userId}", json={"roleId": role_id})
