# Get Support

If you'd like business to enterprise-level support from Rajeh, the current maintainer of Baileys, you can book a video chat. Book a 1 hour time slot by contacting him on Discord or pre-ordering [here](https://purpshell.dev/book). The earlier you pre-order the better, as his time slots usually fill up very quickly. He offers immense value per hour and will answer all your questions before the time runs out.

If you are a business, we encourage you to contribute back to the high development costs of the project and to feed the maintainers who dump tens of hours a week on this. You can do so by booking meetings or sponsoring below. All support, even in bona fide / contribution hours, is welcome by businesses of all sizes. This is not condoning or endorsing businesses to use the library. See the Disclaimer below.

# Sponsor
If you'd like to financially support this project, you can do so by supporting the current maintainer [here](https://purpshell.dev/sponsor).

# Disclaimer
This project is not affiliated, associated, authorized, endorsed by, or in any way officially connected with WhatsApp or any of its subsidiaries or its affiliates.
The official WhatsApp website can be found at whatsapp.com. "WhatsApp" as well as related names, marks, emblems and images are registered trademarks of their respective owners.

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.
Use at your own discretion. Do not spam people with this. We discourage any stalkerware, bulk or automated messaging usage.

- 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 Chromium saves you like **half a gig** of ram :/
- Baileys supports interacting with the multi-device & web versions of WhatsApp.
- Thank you to [@pokearaujo](https://github.com/pokearaujo/multidevice) for writing his observations on the workings of WhatsApp Multi-Device. Also, thank you to [@Sigalor](https://github.com/sigalor/whatsapp-web-reveng) for writing his observations on the workings of WhatsApp Web and thanks to [@Rhymen](https://github.com/Rhymen/go-whatsapp/) 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](#example-to-start) is a simple example of event handling**

> [!TIP]
> **You can see all supported socket configs in the [SocketConfig type alias](https://baileys.wiki/docs/api/type-aliases/SocketConfig/) (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 the [BrowsersMap type alias](https://baileys.wiki/docs/api/type-aliases/BrowsersMap/)**

```ts
import makeWASocket from '@whiskeysockets/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](https://faq.whatsapp.com/1324084875126592/?cms_platform=web)

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

```ts
import makeWASocket from '@whiskeysockets/baileys'

const sock = makeWASocket({
    // can provide additional config here
    printQRInTerminal: false //need to be false
})

if (!sock.authState.creds.registered) {
    const number = 'XXXXXXXXXXX'
    const code = await sock.requestPairingCode(number)
    console.log(code)
}
```

### Receive Full History

1. Set `syncFullHistory` as `true`
2. 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:

```ts
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:

```ts
    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:
    ```ts
    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`
    ```ts
    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:
```ts
import makeWASocket, { useMultiFileAuthState } from '@whiskeysockets/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 in the [BaileysEventMap type alias](https://baileys.wiki/docs/api/type-aliases/BaileysEventMap/)**, it's important you see all events

You can listen to these events like this:
```ts
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

> [!NOTE]
> For reliable serialization of the authentication state, especially when storing as JSON, always use the BufferJSON utility.

```ts
import makeWASocket, { DisconnectReason, useMultiFileAuthState } from '@whiskeysockets/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
```ts
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](#implementing-a-data-store) implementation (in your end)

### Summary of Events on First Connection

1. When you connect first time, `connection.update` will be fired requesting you to restart sock
2. 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:

```ts
import makeWASocket, { makeInMemoryStore } from '@whiskeysockets/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')
// 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
    - **In the [AnyMessageContent type alias](https://baileys.wiki/docs/api/type-aliases/AnyMessageContent/) you can see all message contents supported, like text message**
    - **In the [MiscMessageGenerationOptions type alias](https://baileys.wiki/docs/api/type-aliases/MiscMessageGenerationOptions/) you can see all options supported, like quote message**

```ts
    const jid: string
    const content: AnyMessageContent
    const options: MiscMessageGenerationOptions

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

### Non-Media Messages

#### Text Message
```ts
await sock.sendMessage(jid, { text: 'hello word' })
```

#### Quote Message (works with all types)
```ts
await sock.sendMessage(jid, { text: 'hello word' }, { quoted: message })
```

#### Mention User (works with most types)
- @number is to mention in text, it's optional
```ts
await sock.sendMessage(
    jid,
    {
        text: '@12345678901',
        mentions: ['12345678901@s.whatsapp.net']
    }
)
```

#### Forward Messages
- You need to have message object, can be retrieved from [store](#implementing-a-data-store) or use a [message](https://baileys.wiki/docs/api/type-aliases/WAMessage/) object
```ts
const msg = getMessageFromStore() // implement this on your end
await sock.sendMessage(jid, { forward: msg }) // WA forward the message!
```

#### Location Message
```ts
await sock.sendMessage(
    jid,
    {
        location: {
            degreesLatitude: 24.121231,
            degreesLongitude: 55.1121221
        }
    }
)
```
#### Contact Message
```ts
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](#implementing-a-data-store) or use a [key](https://baileys.wiki/docs/api/type-aliases/WAMessageKey/) object
```ts
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](#implementing-a-data-store) or use a [key](https://baileys.wiki/docs/api/type-aliases/WAMessageKey/) object

- Time can be:

| Time  | Seconds        |
|-------|----------------|
| 24h    | 86.400        |
| 7d     | 604.800       |
| 30d    | 2.592.000     |

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

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

### Sending Messages with Link Previews

1. By default, wa does not have link generation when sent from the web
2. Baileys has a function to generate the content for these link previews
3. To enable this function's usage, add `link-preview-js` as a dependency to your project with `yarn add link-preview-js`
4. Send a link:
```ts
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 in the [WAMediaUpload type alias](https://baileys.wiki/docs/api/type-aliases/WAMediaUpload/)

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

#### Video Message
```ts
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:
    ```bash
        codec: libopus //ogg file
        ac: 1 //one channel
        avoid_negative_ts
        make_zero
    ```
    - Example:
    ```bash
    ffmpeg -i input.mp4 -avoid_negative_ts make_zero -ac 1 output.ogg
    ```
```ts
await sock.sendMessage(
    jid,
    {
        audio: {
            url: './Media/audio.mp3'
        },
        mimetype: 'audio/mp4'
    }
)
```

#### Image Message
```ts
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

```ts
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)

```ts
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](#modifying-chats)

### Editing Messages

- You can pass all editable contents here
```ts
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
```ts
import { createWriteStream } from 'fs'
import { downloadMediaMessage, getContentType } from '@whiskeysockets/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:
```ts
await sock.updateMediaMessage(msg)
```

## Reject Call

- You can obtain `callId` and `callFrom` from `call` event

```ts
await sock.rejectCall(callId, callFrom)
```

## Send States in Chat

### Reading Messages
- A set of message [keys](https://baileys.wiki/docs/api/type-aliases/WAMessageKey/) 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.

```ts
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 the values in the [WAPresence type alias](https://baileys.wiki/docs/api/type-aliases/WAPresence/)
- The presence expires after about 10 seconds.
- This lets the person/group with `jid` know whether you're online, offline, typing etc.

```ts
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
```ts
const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
await sock.chatModify({ archive: true, lastMessages: [lastMsgInChat] }, jid)
```
### Mute/Unmute a Chat

                    fromMe: true // or `false`
                }
            ],

```ts
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:
```ts
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 the [AnyRegularMessageContent type alias](https://baileys.wiki/docs/api/type-aliases/AnyRegularMessageContent/)
- You can add `backgroundColor` and other options in the message options, see the [MiscMessageGenerationOptions type alias](https://baileys.wiki/docs/api/type-aliases/MiscMessageGenerationOptions/)
- `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
```ts
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:
```ts
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](/src/WABinary/readme.md)

### Register a Callback for Websocket Events

> [!TIP]
> Recommended to see `onMessageReceived` function in `socket.ts` file to understand how websockets events are fired

```ts
// 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) => { })
```
