Studio "accept invite" API request?

PhilHub

So, this is an accept invitation button:

I'm working on a project involving the scratch API and it requires that I can accept a studio invite with a http request.

So, if you're confused I'm asking for, what is the URL for accepting a studio invitation? obviously containing the required headers and cookies for example api.scratch.mit.edu/users/griffpatch/messages/count/ for @griffpatch's message count

My friend said it's `scratch.mit.edu/site-api/users/curators-in/{studioId}/add/` but it doesn't seem to work, or maybe its my code?

Here's the code I use for making the request:

print("importing...")

import scratchattach as scratch3
import time
import os
import requests

def accept_invitation(studio, user):
    headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36',
    "x-csrftoken": "a",
    "x-requested-with": "XMLHttpRequest",
    "referer": f"https://scratch.mit.edu/site-api/users/curators-in/{studio}/add/",
    }
    cookies = {
            "scratchsessionsid" : session.session_id,
            "scratchcsrftoken" : "a",
            "scratchlanguage" : "en",
            "accept": "application/json",
            "Content-Type": "application/json",
    }
    response = requests.put(f"https://scratch.mit.edu/site-api/users/curators-in/{studio}/add/", headers=headers, cookies=cookies)
    return response.text
    
print("logging in...")

session = scratch3.login("username", "password")

print("making request...")

print(accept_invitation(34023334, "PhilHub"))

you could try adding the api.___ at the start?

You're probably going to need a session ID on that request.

“obviously containing the required headers and cookies”

Nope, this one uses the other depreciated version. scratch.mit.edu/site-api/

Unfortunately even though I added a session id it still doesn't work. I mean it does go through without any traceback errors, but it returns:

importing...
logging in...
making request...

Please put long things in [code] tags

god286

You probably need to fix the CSRF token, not sure

Done!

If you look at the long text, you will see that it is a 404.

I so far, I used TimMcCool's scratch attach source code as a guide, and it didn't return any traceback errors, which was a thing, but it didn't do the thing I wanted, only returned a lengthy html code of the website.

I used this WORKING script as a guide to make my one:

def invite_curator(self, curator):
        """
        You can only use this function if this object was created using :meth:`scratchattach.session.Session.connect_studio`
        """
        try:
            return requests.put(
                f"https://scratch.mit.edu/site-api/users/curators-in/{self.id}/invite_curator/?usernames={curator}",
                headers = headers,
                cookies = self._cookies,
            ).json()
        except Exception:
            raise(_exceptions.Unauthorized)

I just created an implementation for this in meowclient, a package I made which is similar in purpose to scratchclient/scratchattach but in NodeJS. Here is the code, you may be able to convert this to Python.

await fetch(
  `https://scratch.mit.edu/site-api/users/curators-in/${this.id}/add/?usernames=${this.session.sessionJSON.user.username}`, {
    method: "PUT",
    headers: {
      "User-Agent": UserAgent,
      "X-CSRFToken": this.session.csrfToken,
      Cookie: this.session.cookieSet,
      Origin: "https://scratch.mit.edu",
      Referer: `https://scratch.mit.edu/studios/${this.id}/curators`
    }
  }
);

(Ignore the fact there is no syntax highlighting - the forum hasn't been updated in years so it doesn't understand how to highlight my code unfortunately)

You can use this code here: https://github.com/Sid72020123/scratchconnect/blob/main/scratchconnect/Studio.py#L327

I haven't tested it since many months but it should work…

EDIT: Notice that I used “session.put” with some predefined headers and along-with that, I also added a “referer” header.

This is how the header should look:

headers = {
            "x-csrftoken": self.csrf_token,
            "X-Token": self.token,
            "x-requested-with": "XMLHttpRequest",
            "Cookie": f"scratchcsrftoken={self.csrf_token};scratchlanguage=en;scratchsessionsid={self.session_id};",
            "referer": "https://scratch.mit.edu",
}

Just replace the referer with the studio's URL

Thank you! It works now

Guys, this topic is resolved. How do you close it now? By the way here's the working code which I managed to make with the help of LoidesMio, ProgramORDie, and Sid72020123 (note this code uses the scratchattach module to simplify things)

print("importing...")

import scratchattach as scratch3
import time
import os
import requests

def accept_invitation(studio, user):
    session._get_csrftoken()
    token = session._headers["x-csrftoken"]
    headers = {
    'user-agent': 'Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Mobile Safari/537.36',
    "x-csrftoken": token,
    "x-requested-with": "XMLHttpRequest",
    "referer": "https://scratch.mit.edu/studios/{studio}/curators/",
    }
    cookies = {
            "scratchsessionsid" : session.session_id,
            "scratchcsrftoken" : token,
            "scratchlanguage" : "en",
            "accept": "application/json",
            "Content-Type": "application/json",
    }
    response = requests.put(f"https://scratch.mit.edu/site-api/users/curators-in/{studio}/add/?usernames={user}", headers=headers, cookies=cookies)
    try:
    	return response.json()
    except:
    	return response.status_code
    
print("logging in...")

session = scratch3.login("username", "password")

print("making request...")

print(accept_invitation(studio_id, "username_goes_here")
