Full Documentation

It's a high-performance alternative API to whatsapp, you can send, text messages, files, images, videos and more.

Remember, the API was developed on a platform called RESTful Web services, providing interoperability between computer systems on the Internet.

It uses a set of well-defined operations that apply to all information resources: HTTP itself defines a small set of operations, the most important being POST, GET, PUT and DELETE.

Use it in your favorite language like PHP, Python, C# and others. as long as your language is supported with the HTTP protocol, you will save time and money. you don't need to know how Venom works, we have the complete API documentation, in a professional way!

Getting started

// Supports ES6
// import { create, Whatsapp } from 'venom-bot';
const venom = require('venom-bot');

venom
  .create({
    session: 'session-name' //name of session
  })
  .then((client) => start(client))
  .catch((erro) => {
    console.log(erro);
  });

function start(client) {
  client.onMessage((message) => {
    if (message.body === 'Hi' && message.isGroupMsg === false) {
      client
        .sendText(message.from, 'Welcome Venom 🕷')
        .then((result) => {
          console.log('Result: ', result); //return object success
        })
        .catch((erro) => {
          console.error('Error when sending: ', erro); //return object error
        });
    }
  });
}

After executing create() function, venom will create an instance of whatsapp web. If you are not logged in, it will print a QR code in the terminal. Scan it with your phone and you are ready to go!

Venom will remember the session so there is no need to authenticate everytime.

Multiples sessions can be created at the same time by pasing a session name to create() function:

// Init sales whatsapp bot
venom.create('sales').then((salesClient) => {...});

// Init support whatsapp bot
venom.create('support').then((supportClient) => {...});

Optional create parameters

Venom create() method third parameter can have the following optional parameters:

If you are using the Linux server do not forget to pass the args --user-agent Original parameters in browserArgs

const venom = require('venom-bot');

venom
  .create(
    //session
    'sessionName', //Pass the name of the client you want to start the bot
    //catchQR
    (base64Qrimg, asciiQR, attempts, urlCode) => {
      console.log('Number of attempts to read the qrcode: ', attempts);
      console.log('Terminal qrcode: ', asciiQR);
      console.log('base64 image string qrcode: ', base64Qrimg);
      console.log('urlCode (data-ref): ', urlCode);
    },
    // statusFind

    },
    // options
    {
      browserPathExecutable: '', // browser executable path
      folderNameToken: 'tokens', //folder name when saving tokens
      mkdirFolderToken: '', //folder directory tokens, just inside the venom folder, example:  { mkdirFolderToken: '/node_modules', } //will save the tokens folder in the node_modules directory
      headless: 'new', // you should no longer use boolean false or true, now use false, true or 'new' learn more https://developer.chrome.com/articles/new-headless/
      devtools: false, // Open devtools by default
      debug: false, // Opens a debug session
      logQR: true, // Logs QR automatically in terminal

    },

    // BrowserInstance
    (browser, waPage) => {
      console.log('Browser PID:', browser.process().pid);
      waPage.screenshot({ path: 'screenshot.png' });
    }
  )
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Callback Status Session

Gets the return if the session is isLogged or notLogged or browserClose or qrReadSuccess or qrReadFail or autocloseCalled or desconnectedMobile or deleteToken or chatsAvailable or deviceNotConnected or serverWssNotConnected or noOpenBrowser or initBrowser or openBrowser or connectBrowserWs or initWhatsapp or erroPageWhatsapp or successPageWhatsapp or waitForLogin or waitChat or successChat or Create session wss return "serverClose" case server for close

const venom = require('venom-bot');
venom
  .create('sessionName', undefined, (statusSession, session) => {
    console.log('Status Session: ', statusSession);
    //return isLogged || notLogged || browserClose || qrReadSuccess || qrReadFail || autocloseCalled || desconnectedMobile || deleteToken || chatsAvailable || deviceNotConnected || serverWssNotConnected || noOpenBrowser || initBrowser || openBrowser || connectBrowserWs || initWhatsapp || erroPageWhatsapp || successPageWhatsapp || waitForLogin || waitChat || successChat
    //Create session wss return "serverClose" case server for close
    console.log('Session name: ', session);
  })
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Exporting QR Code

By default QR code will appear on the terminal. If you need to pass the QR somewhere else heres how:

const fs = require('fs');
const venom = require('venom-bot');

venom
  .create(
    'sessionName',
    (base64Qr, asciiQR, attempts, urlCode) => {
      console.log(asciiQR); // Optional to log the QR in the terminal
      var matches = base64Qr.match(/^data:([A-Za-z-+\/]+);base64,(.+)$/),
        response = {};

      if (matches.length !== 3) {
        return new Error('Invalid input string');
      }
      response.type = matches[1];
      response.data = new Buffer.from(matches[2], 'base64');

      var imageBuffer = response;
      require('fs').writeFile(
        'out.png',
        imageBuffer['data'],
        'binary',
        function (err) {
          if (err != null) {
            console.log(err);
          }
        }
      );
    },
    undefined,
    { logQR: false }
  )
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Downloading Files

Puppeteer takes care of the file downloading. The decryption is being done as fast as possible (outruns native methods). Supports big files!

import fs = require('fs');
import mime = require('mime-types');

client.onMessage( async (message) => {
  if (message.isMedia === true || message.isMMS === true) {
    const buffer = await client.decryptFile(message);
    // At this point you can do whatever you want with the buffer
    // Most likely you want to write it into a file
    const fileName = `some-file-name.${mime.extension(message.mimetype)}`;
    fs.writeFile(fileName, buffer, (err) => {
      ...
    });
  }
});

Misc

There are some tricks for a better usage of venom.

Keep session alive:

// function to detect conflits and change status
// Force it to keep the current session
// Possible state values:
// CONFLICT
// CONNECTED
// DEPRECATED_VERSION
// OPENING
// PAIRING
// PROXYBLOCK
// SMB_TOS_BLOCK
// TIMEOUT
// TOS_BLOCK
// UNLAUNCHED
// UNPAIRED
// UNPAIRED_IDLE
client.onStateChange((state) => {
  console.log('State changed: ', state);
  // force whatsapp take over
  if ('CONFLICT'.includes(state)) client.useHere();
  // detect disconnect on whatsapp
  if ('UNPAIRED'.includes(state)) console.log('logout');
});

// DISCONNECTED
// SYNCING
// RESUMING
// CONNECTED
let time = 0;
client.onStreamChange((state) => {
  console.log('State Connection Stream: ' + state);
  clearTimeout(time);
  if (state === 'DISCONNECTED' || state === 'SYNCING') {
    time = setTimeout(() => {
      client.close();
    }, 80000);
  }
});

// function to detect incoming call
client.onIncomingCall(async (call) => {
  console.log(call);
  client.sendText(call.peerJid, "Sorry, I still can't answer calls");
});

Closing (saving) sessions

Close the session properly to ensure the session is saved for the next time you log in (So it won't ask for QR scan again). So instead of CTRL+C,

// Catch ctrl+C
process.on('SIGINT', function() {
  client.close();
});

// Try-catch close
try {
   ...
} catch (error) {
   client.close();
}

Auto closing unsynced sessions

The auto close is enabled by default and the timeout is set to 60 sec. Receives the time in milliseconds to countdown until paired.

Use "autoClose: 0 | false" to disable auto closing.

Debugging

WhatsApp Web Versions

You can use cached versions of WhatsApp Web by passing the webVersion arguments as part of your venom options:

venom.create({
    session: 'sessionname', //name of session
    headless: false,
    logQR: true,
    webVersion: '2.2402.5'
  })
  .then((client) => {
    start(client);
  });

This feature can use any version available in the list at https://github.com/wppconnect-team/wa-version/tree/main/html

Development

Building venom is really simple although it contains 3 main projects inside

1. Wapi project

> npm run build:wapi

2. Middleware

> npm run build:middleware
> npm run build:jsQR

3. Venom

> npm run build:venom

To build the entire project just run

> npm run build
