nextgen-fca - Unofficial Facebook Chat API

This is a fork of the original fca-unofficial repository. This version includes new features and updates that are bundled faster than the main repository. However, be aware that new features may also come with some bugs.

Overview

This API allows you to automate Facebook chat functionalities by emulating the browser's GET/POST requests. It does not work with an auth token and requires a Facebook account's AppState (session information), which is obtained via third-party tools.

Important Notes

Login via Credentials Is No Longer Supported

Due to recent changes, the ability to log in using credentials (i.e., email and password) directly through the API has been disabled. As a result, you cannot use the old login method with your email and password anymore.

api.getAppState finally works!

To use the API, you need to provide an AppState (session information) from a previously authenticated session. You can use api.getAppState() to retrieve and even update your AppState after login.

• Kiwi Browser & c3c-ufc-utility Extension: Extract the AppState using the Kiwi Browser along with the c3c-ufc-utility extension to obtain session cookies after logging into Facebook manually.

Once you have the AppState, you can load it into the API to authenticate. Additionally, api.getAppState() can now be used to update the AppState during the session.

We strongly recommend being responsible when using this API to avoid issues like account bans. Avoid spamming messages, sending large amounts of requests, or using excessive automation.

New Features

1. BypassAutomationBehavior

This feature is designed to bypass certain behavior detection mechanisms from Facebook, which may otherwise flag your actions as automated. By enabling this, your bot's activity will appear more like human interaction, helping reduce the risk of account limitations.

• Configuration: Can be toggled on or off in the NextGen-FCA.json configuration file.

2. AutoRefreshFbDtsg

This feature automatically refreshes the fb_dtsg token, which is used for secure communication with Facebook. Since fb_dtsg tokens expire periodically, this feature ensures your session stays active by refreshing the token automatically without requiring a manual login.

• Configuration: Can be toggled on or off in the NextGen-FCA.json configuration file.

How to Get AppState

1. Kiwi Browser & c3c-ufc-utility Extension
   • Install Kiwi Browser and the c3c-ufc-utility extension.
   • Use the extension to extract your AppState (session cookies) from your Facebook login.
   • Save the AppState as a appstate.json file and load it for logging in.

For more details, check the official c3c-ufc-utility GitHub release.

Install

To install nextgen-fca, use the following npm command:

npm install nextgen-fca

To install the bleeding-edge version directly from GitHub:

npm install nextgen-fca

Example Usage

Here’s how to log in using AppState:

const fs = require('fs');
const login = require('nextgen-fca');

// Load your appState from the saved file
const appState = JSON.parse(fs.readFileSync('appstate.json', 'utf8'));

// Use the appState for login
login({ appState: appState }, (err, api) => {
    if (err) return console.error('Login failed:', err);

    console.log('Successfully logged in!');

    // Example of listening for new messages
    api.listen((err, message) => {
        if (err) return console.error(err);

        // Respond to the received message
        api.sendMessage(message.body, message.threadID);
    });

    // Get and update AppState if needed
    const updatedAppState = api.getAppState();
    fs.writeFileSync('appstate.json', JSON.stringify(updatedAppState));
});

Configuration (NextGen-FCA.json)

The following options can be configured in your NextGen-FCA.json file:

{
  "BypassAutomationBehavior": true,  // Set to false to disable this feature
  "AutoRefreshFbDtsg": true         // Set to false to disable this feature
}
