README

go-whatsapp

Package rhymen/go-whatsapp implements the WhatsApp Web API to provide a clean interface for developers. Big thanks to all contributors of the sigalor/whatsapp-web-reveng project. The official WhatsApp Business API was released in August 2018. You can check it out here.

Installation

go get github.com/adeherysh/go-whatsapp

Usage

Creating a connection
import (
    whatsapp "github.com/adeherysh/go-whatsapp"
)

wac, err := whatsapp.NewConn(20 * time.Second)

The duration passed to the NewConn function is used to timeout login requests. If you have a bad internet connection use a higher timeout value. This function only creates a websocket connection, it does not handle authentication.

Login
qrChan := make(chan string)
go func() {
    fmt.Printf("qr code: %v\n", <-qrChan)
    //show qr code or save it somewhere to scan
}()
sess, err := wac.Login(qrChan)

The authentication process requires you to scan the qr code, that is send through the channel, with the device you are using whatsapp on. The session struct that is returned can be saved and used to restore the login without scanning the qr code again. The qr code has a ttl of 20 seconds and the login function throws a timeout err if the time has passed or any other request fails.

Restore
newSess, err := wac.RestoreWithSession(sess)

The restore function needs a valid session and returns the new session that was created.

Add message handlers
type myHandler struct{}

func (myHandler) HandleError(err error) {
	fmt.Fprintf(os.Stderr, "%v", err)
}

func (myHandler) HandleTextMessage(message whatsapp.TextMessage) {
	fmt.Println(message)
}

func (myHandler) HandleImageMessage(message whatsapp.ImageMessage) {
	fmt.Println(message)
}

func (myHandler) HandleDocumentMessage(message whatsapp.DocumentMessage) {
	fmt.Println(message)
}

func (myHandler) HandleVideoMessage(message whatsapp.VideoMessage) {
	fmt.Println(message)
}

func (myHandler) HandleAudioMessage(message whatsapp.AudioMessage){	
	fmt.Println(message)
}

func (myHandler) HandleJsonMessage(message string) {
	fmt.Println(message)
}

func (myHandler) HandleContactMessage(message whatsapp.ContactMessage) {
	fmt.Println(message)
}

func (myHandler) HandleBatteryMessage(message whatsapp.BatteryMessage) {
	fmt.Println(message)
}

func (myHandler) HandleNewContact(contact whatsapp.Contact) {
	fmt.Println(contact)
}

wac.AddHandler(myHandler{})

The message handlers are all optional, you don't need to implement anything but the error handler to implement the interface. The ImageMessage, VideoMessage, AudioMessage and DocumentMessage provide a Download function to get the media data.

Sending text messages
text := whatsapp.TextMessage{
    Info: whatsapp.MessageInfo{
        RemoteJid: "0123456789@s.whatsapp.net",
    },
    Text: "Hello Whatsapp",
}

err := wac.Send(text)
Sending Contact Messages
contactMessage := whatsapp.ContactMessage{
			Info: whatsapp.MessageInfo{ 
                RemoteJid: "0123456789@s.whatsapp.net", 
                },
			DisplayName: "Luke Skylwallker",
			Vcard: "BEGIN:VCARD\nVERSION:3.0\nN:Skyllwalker;Luke;;\nFN:Luke Skywallker\nitem1.TEL;waid=0123456789:+1 23 456789789\nitem1.X-ABLabel:Mobile\nEND:VCARD",
		}

id, error := client.WaConn.Send(contactMessage)

The message will be send over the websocket. The attributes seen above are the required ones. All other relevant attributes (id, timestamp, fromMe, status) are set if they are missing in the struct. For the time being we only support text messages, but other types are planned for the near future.

Functions

func CheckCurrentServerVersion 

func CheckCurrentServerVersion() ([]int, error)

CheckCurrentServerVersion is based on the login method logic in order to establish the websocket connection and get the current version from the server with the `admin init` command. This can be very useful for automations in which you need to quickly perceive new versions (mostly patches) and update your application so it suddenly stops working.

If you do not want to scan the qr code every time, you should save the returned session and use RestoreWithSession the next time. Login takes a writable channel as an parameter. This channel is used to push the data represented by the qr code back to the user. The received data should be displayed as an qr code in a way you prefer. To print a qr code to console you can use: github.com/Baozisoftware/qrcode-terminal-go Example login procedure: 

wac, err := whatsapp.NewConn(5 * time.Second)
if err != nil {
	panic(err)
}

qr := make(chan string)
go func() {
	terminal := qrcodeTerminal.New()
	terminal.Get(<-qr).Print()
}()

//TODO: GoDoc RestoreWithSession is the function that restores a given session. It will try to reestablish the connection to the WhatsAppWeb servers with the provided session. If it succeeds it will return a new session. This new session has to be saved because the Client and Server-Token will change after every login. Logging in with old tokens is possible, but not suggested. If so, a challenge has to be resolved which is just another possible point of failure.

	SellerJid         string
	Token             string
	TotalAmount1000   int64
	TotalCurrencyCode string
	ContextInfo       ContextInfo
}

type OrderMessageHandler 

type OrderMessageHandler interface {
	Handler
	HandleOrderMessage(message OrderMessage)
}

The OrderMessageHandler interface needs to be implemented to receive order messages dispatched by the dispatcher.

type PhoneInfo 

type PhoneInfo struct {
	Mcc                string
	Mnc                string
	OsVersion          string
	DeviceManufacturer string
	DeviceModel        string
	OsBuildNumber      string
	WaVersion          string
}

type Presence 

type Presence string
const (
	PresenceAvailable   Presence = "available"
	PresenceUnavailable Presence = "unavailable"
	PresenceComposing   Presence = "composing"
	PresenceRecording   Presence = "recording"
	PresencePaused      Presence = "paused"
)

type ProductMessage 

type ProductMessage struct {
	Info             MessageInfo
	Product          *proto.ProductSnapshot
	BusinessOwnerJid string
	Catalog          *proto.CatalogSnapshot
	ContextInfo      ContextInfo
}

type ProductMessageHandler 

type ProductMessageHandler interface {
	Handler
	HandleProductMessage(message ProductMessage)
}

The ProductMessageHandler interface needs to be implemented to receive product messages dispatched by the dispatcher.

type RawMessageHandler 

type RawMessageHandler interface {
	Handler
	HandleRawMessage(message *proto.WebMessageInfo)
}

* The RawMessageHandler interface needs to be implemented to receive raw messages dispatched by the dispatcher. Raw messages are the raw protobuf structs instead of the easy-to-use structs in TextMessageHandler, ImageMessageHandler, etc..

type Session 

type Session struct {
	ClientId    string
	ClientToken string
	ServerToken string
	EncKey      []byte
	MacKey      []byte
	Wid         string
}

Session contains session individual information. To be able to resume the connection without scanning the qr code every time you should save the Session returned by Login and use RestoreWithSession the next time you want to login. Every successful created connection returns a new Session. The Session(ClientToken, ServerToken) is altered after every re-login and should be saved every time.

type StickerMessage 

type StickerMessage struct {
	Info MessageInfo

	Type    string
	Content io.Reader

	ContextInfo ContextInfo
	// contains filtered or unexported fields
}

func (m *StickerMessage) Download() ([]byte, error)

type StickerMessageHandler 

type StickerMessageHandler interface {

}

type SyncHandler

type VideoMessage 

type VideoMessage struct {
	Info        MessageInfo
	Caption     string
	Thumbnail   []byte
	Length      uint32
	Type        string
	Content     io.Reader
	GifPlayback bool

	ContextInfo ContextInfo
	// contains filtered or unexported fields
}

VideoMessage represents a video message. Unexported fields are needed for media up/downloading and media validation. Provide a io.Reader as Content for message sending.

func (*VideoMessage) Download 

func (m *VideoMessage) Download() ([]byte, error)

Download is the function to retrieve media data. The media gets downloaded, validated and returned.

type VideoMessageHandler 

type VideoMessageHandler interface {
	Handler
	HandleVideoMessage(message VideoMessage)
}
