Baileys - Typescript/Javascript WhatsApp Web API

Important Note

This library was originally a project for CS-2362 at Ashoka University and is in no way affiliated with or endorsed by WhatsApp. Use at your own discretion. Do not spam people with this. We discourage any stalkerware, bulk or automated messaging usage.

Liability and License Notice

Baileys and its maintainers cannot be held liable for misuse of this application, as stated in the MIT license. The maintainers of Baileys do not in any way condone the use of this application in practices that violate the Terms of Service of WhatsApp. The maintainers of this application call upon the personal responsibility of its users to use this application in a fair way, as it is intended to be used.

Baileys does not require Selenium or any other browser to be interface with WhatsApp Web, it does so directly using a WebSocket.
Not running Selenium or Chromimum saves you like half a gig of ram :/
Baileys supports interacting with the multi-device & web versions of WhatsApp.
Thank you to @pokearaujo for writing his observations on the workings of WhatsApp Multi-Device. Also, thank you to @Sigalor for writing his observations on the workings of WhatsApp Web and thanks to @Rhymen for the go implementation.

Connecting Account

WhatsApp provides a multi-device API that allows Baileys to be authenticated as a second WhatsApp client by scanning a QR code or Pairing Code with WhatsApp on your phone.

Note

Here is a simple example of event handling

Tip

You can see all supported socket configs here (Recommended)

Starting socket with QR-CODE

Tip

You can customize browser name if you connect with QR-CODE, with Browser constant, we have some browsers config, see here

import makeWASocket from 'baileys'

const sock = makeWASocket({
    // can provide additional config here
    browser: Browsers.ubuntu('My App'),
    printQRInTerminal: true
})

If the connection is successful, you will see a QR code printed on your terminal screen, scan it with WhatsApp on your phone and you'll be logged in!

Starting socket with Pairing Code

Important

Pairing Code isn't Mobile API, it's a method to connect Whatsapp Web without QR-CODE, you can connect only with one device, see here

The phone number can't have + or () or -, only numbers, you must provide country code

import makeWASocket from 'baileys'

const sock = makeWASocket({
    // can provide additional config here
    printQRInTerminal: false //need to be false
})
// NOTE: WAIT TILL QR EVENT BEFORE REQUESTING THE PAIRING CODE
if (!sock.authState.creds.registered) {
    const number = 'XXXXXXXXXXX'
    const code = await sock.requestPairingCode(number)
    console.log(code)
}

Receive Full History

Set syncFullHistory as true
Baileys, by default, use chrome browser config
- If you'd like to emulate a desktop connection (and receive more message history), this browser setting to your Socket config:

const sock = makeWASocket({
    ...otherOpts,
    // can use Windows, Ubuntu here too
    browser: Browsers.macOS('Desktop'),
    syncFullHistory: true
})

Important Notes About Socket Config

Caching Group Metadata (Recommended)

If you use baileys for groups, we recommend you to set cachedGroupMetadata in socket config, you need to implement a cache like this:

const groupCache = new NodeCache({stdTTL: 5 * 60, useClones: false})

const sock = makeWASocket({
    cachedGroupMetadata: async (jid) => groupCache.get(jid)
})

sock.ev.on('groups.update', async ([event]) => {
    const metadata = await sock.groupMetadata(event.id)
    groupCache.set(event.id, metadata)
})

sock.ev.on('group-participants.update', async (event) => {
    const metadata = await sock.groupMetadata(event.id)
    groupCache.set(event.id, metadata)
})

Improve Retry System & Decrypt Poll Votes

If you want to improve sending message, retrying when error occurs and decrypt poll votes, you need to have a store and set getMessage config in socket like this:
```
const sock = makeWASocket({
    getMessage: async (key) => await getMessageFromStore(key)
})
```

Receive Notifications in Whatsapp App

If you want to receive notifications in whatsapp app, set markOnlineOnConnect to false
```
const sock = makeWASocket({
    markOnlineOnConnect: false
})
```

Saving & Restoring Sessions

You obviously don't want to keep scanning the QR code every time you want to connect.

So, you can load the credentials to log back in:

import makeWASocket, { useMultiFileAuthState } from 'baileys'

const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')

// will use the given state to connect
// so if valid credentials are available -- it'll connect without QR
const sock = makeWASocket({ auth: state })

// this will be called as soon as the credentials are updated
sock.ev.on('creds.update', saveCreds)

Important

useMultiFileAuthState is a utility function to help save the auth state in a single folder, this function serves as a good guide to help write auth & key states for SQL/no-SQL databases, which I would recommend in any production grade system.

Note

When a message is received/sent, due to signal sessions needing updating, the auth keys (authState.keys) will update. Whenever that happens, you must save the updated keys (authState.keys.set() is called). Not doing so will prevent your messages from reaching the recipient & cause other unexpected consequences. The useMultiFileAuthState function automatically takes care of that, but for any other serious implementation -- you will need to be very careful with the key state management.

Handling Events

Baileys uses the EventEmitter syntax for events. They're all nicely typed up, so you shouldn't have any issues with an Intellisense editor like VS Code.

Important

The events are these, it's important you see all events

You can listen to these events like this:

const sock = makeWASocket()
sock.ev.on('messages.upsert', ({ messages }) => {
    console.log('got messages', messages)
})

Example to Start

Note

This example includes basic auth storage too

import makeWASocket, { DisconnectReason, useMultiFileAuthState } from 'baileys'
import { Boom } from '@hapi/boom'

async function connectToWhatsApp () {
    const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')
    const sock = makeWASocket({
        // can provide additional config here
        auth: state,
        printQRInTerminal: true
    })
    sock.ev.on('connection.update', (update) => {
        const { connection, lastDisconnect } = update
        if(connection === 'close') {
            const shouldReconnect = (lastDisconnect.error as Boom)?.output?.statusCode !== DisconnectReason.loggedOut
            console.log('connection closed due to ', lastDisconnect.error, ', reconnecting ', shouldReconnect)
            // reconnect if not logged out
            if(shouldReconnect) {
                connectToWhatsApp()
            }
        } else if(connection === 'open') {
            console.log('opened connection')
        }
    })
    sock.ev.on('messages.upsert', event => {
        for (const m of event.messages) {
            console.log(JSON.stringify(m, undefined, 2))

            console.log('replying to', m.key.remoteJid)
            await sock.sendMessage(m.key.remoteJid!, { text: 'Hello Word' })
        }
    })

    // to storage creds (session info) when it updates
    sock.ev.on('creds.update', saveCreds)
}
// run in main file
connectToWhatsApp()

Important

In messages.upsert it's recommended to use a loop like for (const message of event.messages) to handle all messages in array

Decrypt Poll Votes

By default poll votes are encrypted and handled in messages.update
That's a simple example

sock.ev.on('messages.update', event => {
    for(const { key, update } of event) {
        if(update.pollUpdates) {
            const pollCreation = await getMessage(key)
            if(pollCreation) {
                console.log(
                    'got poll update, aggregation: ',
                    getAggregateVotesInPollMessage({
                        message: pollCreation,
                        pollUpdates: update.pollUpdates,
                    })
                )
            }
        }
    }
})

getMessage is a store implementation (in your end)

Summary of Events on First Connection

When you connect first time, connection.update will be fired requesting you to restart sock
Then, history messages will be received in messaging.history-set

Implementing a Data Store

Baileys does not come with a defacto storage for chats, contacts, or messages. However, a simple in-memory implementation has been provided. The store listens for chat updates, new messages, message updates, etc., to always have an up-to-date version of the data.

Important

I highly recommend building your own data store, as storing someone's entire chat history in memory is a terrible waste of RAM.

It can be used as follows:

import makeWASocket, { makeInMemoryStore } from 'baileys'
// the store maintains the data of the WA connection in memory
// can be written out to a file & read from it
const store = makeInMemoryStore({ })
// can be read from a file
store.readFromFile('./baileys_store.json')
/
B93C
/ saves the state to a file every 10s
setInterval(() => {
    store.writeToFile('./baileys_store.json')
}, 10_000)

const sock = makeWASocket({ })
// will listen from this socket
// the store can listen from a new socket once the current socket outlives its lifetime
store.bind(sock.ev)

sock.ev.on('chats.upsert', () => {
    // can use 'store.chats' however you want, even after the socket dies out
    // 'chats' => a KeyedDB instance
    console.log('got chats', store.chats.all())
})

sock.ev.on('contacts.upsert', () => {
    console.log('got contacts', Object.values(store.contacts))
})

The store also provides some simple functions such as loadMessages that utilize the store to speed up data retrieval.

Whatsapp IDs Explain

id is the WhatsApp ID, called jid too, of the person or group you're sending the message to.
- It must be in the format [country code][phone number]@s.whatsapp.net
  - Example for people: +19999999999@s.whatsapp.net.
  - For groups, it must be in the format 123456789-123345@g.us.
- For broadcast lists, it's [timestamp of creation]@broadcast.
- For stories, the ID is status@broadcast.

Utility Functions

getContentType, returns the content type for any message
getDevice, returns the device from message
makeCacheableSignalKeyStore, make auth store more fast
downloadContentFromMessage, download content from any message

Sending Messages

Send all types of messages with a single function
- Here you can see all message contents supported, like text message
- Here you can see all options supported, like quote message
```
const jid: string
const content: AnyMessageContent
const options: MiscMessageGenerationOptions

sock.sendMessage(jid, content, options)
```

Non-Media Messages

Text Message

await sock.sendMessage(jid, { text: 'hello word' })

Quote Message (works with all types)

await sock.sendMessage(jid, { text: 'hello word' }, { quoted: message })

Mention User (works with most types)

@number is to mention in text, it's optional

await sock.sendMessage(
    jid,
    {
        text: '@12345678901',
        mentions: ['12345678901@s.whatsapp.net']
    }
)

Forward Messages

You need to have message object, can be retrieved from store or use a message object

const msg = getMessageFromStore() // implement this on your end
await sock.sendMessage(jid, { forward: msg }) // WA forward the message!

Location Message

await sock.sendMessage(
    jid, 
    {
        location: {
            degreesLatitude: 24.121231,
            degreesLongitude: 55.1121221
        }
    }
)

Contact Message

const vcard = 'BEGIN:VCARD\n' // metadata of the contact card
            + 'VERSION:3.0\n' 
            + 'FN:Jeff Singh\n' // full name
            + 'ORG:Ashoka Uni;\n' // the organization of the contact
            + 'TEL;type=CELL;type=VOICE;waid=911234567890:+91 12345 67890\n' // WhatsApp ID + phone number
            + 'END:VCARD'

await sock.sendMessage(
    id,
    { 
        contacts: { 
            displayName: 'Jeff', 
            contacts: [{ vcard }] 
        }
    }
)

Reaction Message

You need to pass the key of message, you can retrieve from store or use a key object

await sock.sendMessage(
    jid,
    {
        react: {
            text: '💖', // use an empty string to remove the reaction
            key: message.key
        }
    }
)

Pin Message

You need to pass the key of message, you can retrieve from store or use a key object
Time can be:

Time	Seconds
24h	86.400
7d	604.800
30d	2.592.000

await sock.sendMessage(
    jid,
    {
        pin: {
            type: 1, // 0 to remove
            time: 86400
            key: message.key
        }
    }
)

Poll Message

await sock.sendMessage(
    jid,
    {
        poll: {
            name: 'My Poll',
            values: ['Option 1', 'Option 2', ...],
            selectableCount: 1,
            toAnnouncementGroup: false // or true
        }
    }
)

Sending Messages with Link Previews

By default, wa does not have link generation when sent from the web
Baileys has a function to generate the content for these link previews
To enable this function's usage, add link-preview-js as a dependency to your project with yarn add link-preview-js
Send a link:

await sock.sendMessage(
    jid,
    {
        text: 'Hi, this was sent using https://github.com/whiskeysockets/baileys'
    }
)

Media Messages

Sending media (video, stickers, images) is easier & more efficient than ever.

Note

In media messages, you can pass { stream: Stream } or { url: Url } or Buffer directly, you can see more here

When specifying a media url, Baileys never loads the entire buffer into memory; it even encrypts the media as a readable stream.

Tip

It's recommended to use Stream or Url to save memory

Gif Message

Whatsapp doesn't support .gif files, that's why we send gifs as common .mp4 video with gifPlayback flag

await sock.sendMessage(
    jid, 
    { 
        video: fs.readFileSync('Media/ma_gif.mp4'),
        caption: 'hello word',
        gifPlayback: true
    }
)

Video Message

await sock.sendMessage(
    id, 
    { 
        video: {
            url: './Media/ma_gif.mp4'
        },
        caption: 'hello word',
	    ptv: false // if set to true, will send as a `video note`
    }
)

Audio Message

To audio message work in all devices you need to convert with some tool like ffmpeg with this flags:

    codec: libopus //ogg file
    ac: 1 //one channel
    avoid_negative_ts
    make_zero

Example:

ffmpeg -i input.mp4 -avoid_negative_ts make_zero -ac 1 output.ogg

await sock.sendMessage(
    jid, 
    {
        audio: {
            url: './Media/audio.mp3'
        },
        mimetype: 'audio/mp4'
    }
)

Image Message

await sock.sendMessage(
    id, 
    { 
        image: {
            url: './Media/ma_img.png'
        },
        caption: 'hello word'
    }
)

View Once Message

You can send all messages above as viewOnce, you only need to pass viewOnce: true in content object

await sock.sendMessage(
    id, 
    { 
        image: {
            url: './Media/ma_img.png'
        },
        viewOnce: true, //works with video, audio too
        caption: 'hello word'
    }
)

Modify Messages

Deleting Messages (for everyone)

const msg = await sock.sendMessage(jid, { text: 'hello word' })
await sock.sendMessage(jid, { delete: msg.key })

Note: deleting for oneself is supported via chatModify, see in this section

Editing Messages

You can pass all editable contents here

await sock.sendMessage(jid, {
      text: 'updated text goes here',
      edit: response.key,
    });

Manipulating Media Messages

Thumbnail in Media Messages

For media messages, the thumbnail can be generated automatically for images & stickers provided you add jimp or sharp as a dependency in your project using yarn add jimp or yarn add sharp.
Thumbnails for videos can also be generated automatically, though, you need to have ffmpeg installed on your system.

Downloading Media Messages

If you want to save the media you received

import { createWriteStream } from 'fs'
import { downloadMediaMessage, getContentType } from 'baileys'

sock.ev.on('messages.upsert', async ({ [m] }) => {
    if (!m.message) return // if there is no text or media message
    const messageType = getContentType(m) // get what type of message it is (text, image, video...)

    // if the message is an image
    if (messageType === 'imageMessage') {
        // download the message
        const stream = await downloadMediaMessage(
            m,
            'stream', // can be 'buffer' too
            { },
            { 
                logger,
                // pass this so that baileys can request a reupload of media
                // that has been deleted
                reuploadRequest: sock.updateMediaMessage
            }
        )
        // save to file
        const writeStream = createWriteStream('./my-download.jpeg')
        stream.pipe(writeStream)
    }
}

Re-upload Media Message to Whatsapp

WhatsApp automatically removes old media from their servers. For the device to access said media -- a re-upload is required by another device that has it. This can be accomplished using:

await sock.updateMediaMessage(msg)

Reject Call

You can obtain callId and callFrom from call event

await sock.rejectCall(callId, callFrom)

Send States in Chat

Reading Messages

A set of message keys must be explicitly marked read now.
You cannot mark an entire 'chat' read as it were with Baileys Web. This means you have to keep track of unread messages.

const key: WAMessageKey
// can pass multiple keys to read multiple messages as well
await sock.readMessages([key])

The message ID is the unique identifier of the message that you are marking as read. On a WAMessage, the messageID can be accessed using messageID = message.key.id.

Update Presence

presence can be one of these
The presence expires after about 10 seconds.
This lets the person/group with jid know whether you're online, offline, typing etc.

await sock.sendPresenceUpdate('available', jid)

Note

If a desktop client is active, WA doesn't send push notifications to the device. If you would like to receive said notifications -- mark your Baileys client offline using sock.sendPresenceUpdate('unavailable')

Modifying Chats

WA uses an encrypted form of communication to send chat/app updates. This has been implemented mostly and you can send the following updates:

Important

If you mess up one of your updates, WA can log you out of all your devices and you'll have to log in again.

Archive a Chat

const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
await sock.chatModify({ archive: true, lastMessages: [lastMsgInChat] }, jid)

Mute/Unmute a Chat

Supported times:

Time	Miliseconds
Remove	null
8h	86.400.000
7d	604.800.000

// mute for 8 hours
await sock.chatModify({ mute: 8 * 60 * 60 * 1000 }, jid)
// unmute
await sock.chatModify({ mute: null }, jid)

Mark a Chat Read/Unread

const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
// mark it unread
await sock.chatModify({ markRead: false, lastMessages: [lastMsgInChat] }, jid)

Delete a Message for Me

await sock.chatModify(
    {
        clear: {
            messages: [
                {
                    id: 'ATWYHDNNWU81732J',
                    fromMe: true, 
                    timestamp: '1654823909'
                }
            ]
        }
    }, 
    jid
)

Delete a Chat

const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
await sock.chatModify({
        delete: true,
        lastMessages: [
            {
                key: lastMsgInChat.key,
                messageTimestamp: lastMsgInChat.messageTimestamp
            }
        ]
    },
    jid
)

Pin/Unpin a Chat

await sock.chatModify({
        pin: true // or `false` to unpin
    },
    jid
)

Star/Unstar a Message

await sock.chatModify({
        star: {
            messages: [
                {
                    id: 'messageID',
                    fromMe: true // or `false`
                }
            ],
            star: true // - true: Star Message; false: Unstar Message
        }
    },
    jid
)

Disappearing Messages

Ephemeral can be:

Time	Seconds
Remove	0
24h	86.400
7d	604.800
90d	7.776.000

You need to pass in Seconds, default is 7 days

// turn on disappearing messages
await sock.sendMessage(
    jid, 
    // this is 1 week in seconds -- how long you want messages to appear for
    { disappearingMessagesInChat: WA_DEFAULT_EPHEMERAL }
)

// will send as a disappearing message
await sock.sendMessage(jid, { text: 'hello' }, { ephemeralExpiration: WA_DEFAULT_EPHEMERAL })

// turn off disappearing messages
await sock.sendMessage(
    jid, 
    { disappearingMessagesInChat: false }
)

User Querys

Check If ID Exists in Whatsapp

const [result] = await sock.onWhatsApp(jid)
if (result.exists) console.log (`${jid} exists on WhatsApp, as jid: ${result.jid}`)

Query Chat History (groups too)

You need to have oldest message in chat

const msg = await getOldestMessageInChat(jid)
await sock.fetchMessageHistory(
    50, //quantity (max: 50 per query)
    msg.key,
    msg.messageTimestamp
)

Messages will be received in messaging.history-set event

Fetch Status

const status = await sock.fetchStatus(jid)
console.log('status: ' + status)

Fetch Profile Picture (groups too)

To get the display picture of some person/group

// for low res picture
const ppUrl = await sock.profilePictureUrl(jid)
console.log(ppUrl)

// for high res picture
const ppUrl = await sock.profilePictureUrl(jid, 'image')

Fetch Bussines Profile (such as description or category)

const profile = await sock.getBusinessProfile(jid)
console.log('business description: ' + profile.description + ', category: ' + profile.category)

Fetch Someone's Presence (if they're typing or online)

// the presence update is fetched and called here
sock.ev.on('presence.update', console.log)

// request updates for a chat
await sock.presenceSubscribe(jid)

Change Profile

Change Profile Status

await sock.updateProfileStatus('Hello World!')

Change Profile Name

await sock.updateProfileName('My name')

Change Display Picture (groups too)

To change your display picture or a group's

Note

Like media messages, you can pass { stream: Stream } or { url: Url } or Buffer directly, you can see more here

await sock.updateProfilePicture(jid, { url: './new-profile-picture.jpeg' })

Remove display picture (groups too)

await sock.removeProfilePicture(jid)

Groups

To change group properties you need to be admin

Create a Group

// title & participants
const group = await sock.groupCreate('My Fab Group', ['1234@s.whatsapp.net', '4564@s.whatsapp.net'])

await sock.sendMessage(group.id, { text: 'hello there' }) // say hello to everyone on the group

Add/Remove or Demote/Promote

// id & people to add to the group (will throw error if it fails)
await sock.groupParticipantsUpdate(
    jid, 
    ['abcd@s.whatsapp.net', 'efgh@s.whatsapp.net'],
    'add' // replace this parameter with 'remove' or 'demote' or 'promote'
)

Change Subject (name)

await sock.groupUpdateSubject(jid, 'New Subject!')

Change Description

await sock.groupUpdateDescription(jid, 'New Description!')

Change Settings

// only allow admins to send messages

// allow everyone to modify the group's settings -- like display picture etc.
await sock.groupSettingUpdate(jid, 'unlocked')
// only allow admins to modify the group's settings
await sock.groupSettingUpdate(jid, 'locked')

Leave a Group

// will throw error if it fails
await sock.groupLeave(jid)

7d	604.800
90d	7.776.000

const ephemeral = 86400 
await sock.updateDefaultDisappearingMode(ephemeral)

Broadcast Lists & Stories

Send Broadcast & Stories

Messages can be sent to broadcasts & stories. You need to add the following message options in sendMessage, like this:

await sock.sendMessage(
    jid,
    {
        image: {
            url: url
        },
        caption: caption
    },
    {
        backgroundColor: backgroundColor,
        font: font,
        statusJidList: statusJidList,
        broadcast: true
    }
)

Message body can be a extendedTextMessage or imageMessage or videoMessage or voiceMessage, see here
You can add backgroundColor and other options in the message options, see here
broadcast: true enables broadcast mode
statusJidList: a list of people that you can get which you need to provide, which are the people who will get this status message.
You can send messages to broadcast lists the same way you send messages to groups & individual chats.
Right now, WA Web does not support creating broadcast lists, but you can still delete them.
Broadcast IDs are in the format 12345678@broadcast

Query a Broadcast List's Recipients & Name

const bList = await sock.getBroadcastListInfo('1234@broadcast')
console.log (`list name: ${bList.name}, recps: ${bList.recipients}`)

Writing Custom Functionality

Baileys is written with custom functionality in mind. Instead of forking the project & re-writing the internals, you can simply write your own extensions.

Enabling Debug Level in Baileys Logs

First, enable the logging of unhandled messages from WhatsApp by setting:

const sock = makeWASocket({
    logger: P({ level: 'debug' }),
})

This will enable you to see all sorts of messages WhatsApp sends in the console.

How Whatsapp Communicate With Us

Tip

If you want to learn whatsapp protocol, we recommend to study about Libsignal Protocol and Noise Protocol

Example: Functionality to track the battery percentage of your phone. You enable logging and you'll see a message about your battery pop up in the console:

{
    "level": 10,
    "fromMe": false,
    "frame": {
        "tag": "ib",
        "attrs": {
            "from": "@s.whatsapp.net"
        },
        "content": [
            {
                "tag": "edge_routing",
                "attrs": {},
                "content": [
                    {
                        "tag": "routing_info",
                        "attrs": {},
                        "content": {
                            "type": "Buffer",
                            "data": [8,2,8,5]
                        }
                    }
                ]
            }
        ]
    },
    "msg":"communication"
}

The 'frame' is what the message received is, it has three components:

tag -- what this frame is about (eg. message will have 'message')
attrs -- a string key-value pair with some metadata (contains ID of the message usually)
content -- the actual data (eg. a message node will have the actual message content in it)
read more about this format here

Register a Callback for Websocket Events

Tip

Recommended to see onMessageReceived function in socket.ts file to understand how websockets events are fired

// for any message with tag 'edge_routing'
sock.ws.on('CB:edge_routing', (node: BinaryNode) => { })

// for any message with tag 'edge_routing' and id attribute = abcd
sock.ws.on('CB:edge_routing,id:abcd', (node: BinaryNode) => { })

// for any message with tag 'edge_routing', id attribute = abcd & first content node routing_info
sock.ws.on('CB:edge_routing,id:abcd,routing_info', (node: BinaryNode) => { })

Also, this repo is now licenced under GPL 3 since it uses libsignal-node
