Installation

To install this repository as your dependency, use following command with authorized git client:

yarn add git+https://github.com/Seia-Soto/clubhouse-api#[TAG]

Usage

For working example, you can refer /example folder of this repository. Also, about parameters for each API call functions, you need to inspect functions manually with notes that included with functions.

Scripts

yarn example

Runs example code.

yarn profile

Create new prorfile JSON data by authenticating manually on command line shell.

Reverse Engineering

To reverse engineer Clubhouse audio chat application, only thing we need is jailbroken device. Because there is nothing else except for SSL certificate pinning and we can bypass it even on iOS 14 which is the latest release of iOS by installing some tweaks.

Jailbreaking

Use Odyssey, if you're on iOS 13.6 or higher.

To jailbreak, I recommend you to use Unc0ver instead of others due to stability. Setup AltServer on your PC or Mac and then install Unc0ver

iOS 14

You're not able to use checkm8 exploit if you're on iPhone 11 or higher (higher than A11).

If you're on iOS 14 or higher version, use Checkra1n version 0.12.1 to jailbreak. This this time, you need to disable your iPhone's passcode manually before jailbreaking. Also, DO NOT USE LATEST RELEASE of checkra1n to avoid issue on A11.

Post installation

If you install OpenSSH server to debug on remote PC, you need to CHANGE BOTH root AND mobile USER'S PASSWORD.

passwd root
passwd mobile

Setting up MITM proxy

You can set up MITM proxy with following tools:

• Fiddler, download directly (Windows).
• MITM Proxy, download directly (Windows).

Install toolchains and follow steps to decrypt HTTPS traffics:

Fiddler

You need to configure fiddler via the official guide.

MITM Proxy

If you've setup MITM proxy, open http://mitm.it on your iPhone, then install certificate.

Bypassing SSL Pinning

To inspect HTTP packet, there are ways to bypass it easily.

ssl-kill-switch

Install required updates from Cydia for security reasons and install Filza File Manager or terminal emulator to install package file manually. Open following repo and download latest release from it. If you touch share button and then share the file to filza, you can directly install package file.

• nabla/ssl-kill-switch2

After installation, turn it on in settings app.

frida-ios-hook

Install iTunes and Python3 on your PC and open iTunes after install. Connect to your iPhone shell via methods described in Wireshark remote debugging section. Clone following repository to some directory:

• noobpk/frida-ios-hook

After, all things are ready, run script via following command:

python3 hook.py -n clubhouse -s frida-scripts\bypass-ssl-ios13.js

• The script also works on iOS 14.

Wireshark remote debugging

By piping stream over SSH, you can also debug your iPhone's traffic with wireshark installed on PC. Before doing this, install OpenSSH and tcpdump tweak on your iPhone and install Wireshark on your PC.

You may add following paths to system wide environment variable:

• C:\Program Files\Wireshark

After setting up itunnel-mux or 3uTools from below, open new command line window and start debugging with built-in ssh on Windows 10.

ssh root@localhost -p 2222 -l root tcpdump -s 0 -U -n -w - -i any not port 22 | wireshark -k -i -

itunnel-mux

Download itunnel_mux_rev71.zip from following webpage and add it to path. At this time, you should install iTunes and Apple Mobile Support before continuing.

• Google Code Archive/iphonetunnel-usbmuxconnectbyport

Open it and start proxy after connecting iPhone.

itunnel_mux --iport 22 --lport 22

3uTools

Also, you can do this easier with 3uTools which only available on Windows. Download and install it to your PC and connect iPhone via USB. Then you can go to Toolbox tab and click Open SSH Tunnel to open SSH port locally.

API

About the API implemented in this project. Only special things will be typed.

Browser support

The code is also available for common web browser as this project doesn't contain any code that requires additional C code build. However, there are many ban reports from web browser use, so if you want to use this on web browser, you should build proxy server.

Voice support

Update 2021/02/21

Voice-related support will not present after today because it is PART OF AGORA, not CLUBHOUSE.

Actually, the capacity of voice support is already present in my repository since src/api/joinChannel.js method implemented. However, there is not enough information to keep users safe from unexpected bans, and I couldn't say You can use this to do Clubhouse!. Other unofficial repositories are already doing voice stuff with Agora SDK built for their language, but I couldn't say that is safe to use. Because, commonly for who operating production service can see every users connecting to specific gateway and it is easy to detect what users are using if user didn't change any thing on official SDK. In future, I am planning to port iOS's Agora voice SDK into Node.JS to reduce ban rate. However, limitation of my iOS ecosystem knowledge, currently only official JavaScript SDK is available to use and there is a huge limitation, which requires web browser context.

For additional information about SDK, please refer:

• AgoraWebSDK NG API Docs

NG is Next Generation in Agora Ecosystem.*

Electron applications

For Electron based applications, you can easily integrate Agora with my clubhouse-api package. You can see the example that describes how to get RTM token stuff in src/structures/voice.js.

For additional information about Electron SDK, please refer:

• AgoraIO/Electron-SDK

client.getStatic(url)

client.getStatic method will return a cross-fetch agent which having essential headers to query static files. For example, you can download profile picture safely by using this method.

const download = url => {
  const fs = require('fs')

  const response = await app.getStatic(url)
  const stream = fs.createWriteStream('./avatar.png')

  return new Promise((resolve, reject) => {
    response.body.pipe(stream)
    response.body.on('error', reject)

    stream.on('finish', resolve)
  })
}

fetch option overrides

To override cross-fetch option object, you need to provide re-usable object to profile.fetchOptions.

const profile = {
  ...profiles.application.a304,
  ...profiles.locales.Korean,
  fetchOptions: {
    agent: ... // NOTE: For proxy stuff;
  }
}
