Added features:

• Once the error is detected it will automatically relogin the appstate.
• If the appstate itself is logged out it will automatically logged out and you can resubmit it again, But aside of that, if it has an automated behavior, it will relogin then it will dismiss automatically and refreshes the login

• Added a feature where if the account is locked/suspended, it will stop the login process and shows the information and why it was locked/suspended.

No need to put on listenMqtt.

Also some other features:

• Added api.ws3.relogin()
• Added api.stopListenMqtt()
• Added api.getRegion()
• Added api.setProfileGuard()
• Added api.addFunctions()
• Fixed api functions including api.follow()
• Changed npmlog to normal console.log due to render log issues
• Added a detection if it's locked or suspended (will show the information about the lock/suspension)
• Tested on Mirai/Autobot (try on Xavia or Goat)

Based on hut-chat-api by Jonell Magallanes

Facebook now has an official API for chat bots here.

Session Account Note:

• You can use cookies editor available in kiwi browser, edge and chrome extension for pc and i recommended use Mozila Firefox to less logout or use this website if you have no acess these broswer specially iphone os user this use Appstate Getter https://joncll.serv00.net/apst.html

This API is the only way to automate chat functionalities on a user account. We do this by emulating the browser. This means doing the exact same GET/POST requests and tricking Facebook into thinking we're accessing the website normally. Because we're doing it this way, this API won't work with an auth token but requires the credentials of a Facebook account.

Disclaimer: We are not responsible if your account gets banned for spammy activities such as sending lots of messages to people you don't know, sending messages very quickly, sending spammy looking URLs, logging in and out very quickly... Be responsible Facebook citizens.

See below for projects using this API.

Install

If you just want to use ws3-fca, you should use this command:

npm install ws3-fca@latest

It will download ws3-fca from NPM repositories

Example Usage

const login = require("ws3-fca");

// Create simple echo bot
login({
  appState: []
}, (err, api) => {
    if (err) return console.error(err);
    api.listenMqtt((err, event) => {
        api.sendMessage(event.body, event.threadID);
    });
});

Result:

Main Functionality

Sending a message

api.sendMessage(message, threadID[, callback][, messageID])

Various types of message can be sent:

• Regular: set field body to the desired message as a string.
• Sticker: set a field sticker to the desired sticker ID.
• File or image: Set field attachment to a readable stream or an array of readable streams.
• URL: set a field url to the desired URL.
• Emoji: set field emoji to the desired emoji as a string and set field emojiSize with size of the emoji (small, medium, large)

Note that a message can only be a regular message (which can be empty) and optionally one of the following: a sticker, an attachment or a url.

Tip: to find your own ID, you can look inside the cookies. The userID is under the name c_user.

Example (Basic Message)

const login = require("ws3-fca");

login({email: "FB_EMAIL", password: "FB_PASSWORD"}, (err, api) => {
    if(err) return console.error(err);

    var yourID = "000000000000000";
    var msg = "Hey!";
    api.sendMessage(msg, yourID);
});

Example (File upload)

const login = require("ws3-fca");

login({email: "FB_EMAIL", password: "FB_PASSWORD"}, (err, api) => {
    if(err) return console.error(err);

    // Note this example uploads an image called image.jpg
    var yourID = "000000000000000";
    var msg = {
        body: "Hey!",
        attachment: fs.createReadStream(__dirname + '/image.jpg')
    }
    api.sendMessage(msg, yourID);
});

Saving session.

To avoid logging in every time you should save AppState (cookies etc.) to a file, then you can use it without having password in your scripts.

Example

const fs = require("fs");
const login = require("ws3-fca");

var credentials = {email: "FB_EMAIL", password: "FB_PASSWORD"};

login(credentials, (err, api) => {
    if(err) return console.error(err);

    fs.writeFileSync('appstate.json', JSON.stringify(api.getAppState()));
});

Alternative: Use c3c-fbstate to get fbstate.json (appstate.json)

Listening to a chat

api.listenMqtt(callback)

Listen watches for messages sent in a chat. By default this won't receive events (joining/leaving a chat, title change etc…) but it can be activated with api.setOptions({listenEvents: true}). This will by default ignore messages sent by the current account, you can enable listening to your own messages with api.setOptions({selfListen: true}).

Example

const fs = require("fs");
const login = require("ws3-fca");

// Simple echo bot. It will repeat everything that you say.
// Will stop when you say '/stop'
login({appState: JSON.parse(fs.readFileSync('appstate.json', 'utf8'))}, (err, api) => {
    if(err) return console.error(err);

    api.setOptions({listenEvents: true});

    var stopListening = api.listenMqtt((err, event) => {
        if( err) return console.error(err);

        api.markAsRead(event.threadID, (err) => {
            if(err) console.error(err);
        });

        switch(event.type) {
            case "message":
                if(event.body === '/stop') {
                    api.sendMessage("Goodbye…", event.threadID);
                    return stopListening();
                }
                api.sendMessage("TEST BOT: " + event.body, event.threadID);
                break;
            case "event":
                console.log(event);
                break;
        }
    });
});
