WhatsApp

Prerequisites

You will need a registered WhatsApp phone number to be used as source for sending WhatsApp messages.

Usage

In the current implementation, authentication is implemented using 2 ways:

1. Scanning QR code from terminal using a registered WhatsApp device.

   • Go to WhatsApp on your device.
   • Click on the ellipsis icon (3 vertical dots) on top right, then click on "WhatsApp Web".
   • Click on the "+" icon and scan the QR code from terminal.

Refer: Login (go-whatsapp) and sigalor/whatsapp-web-reveng for more details.

2. Providing the Session credentials explicitly.

package main

import (
        "log"

        "github.com/nikoksr/notify"
        "github.com/nikoksr/notify/service/whatsapp"
)

func main() {
        whatsappSvc, err := whatsapp.New()
        if err != nil {
                log.Fatalf("whatsapp.New() failed: %s", err.Error())
        }

        err = whatsappSvc.LoginWithQRCode()
        if err != nil {
                log.Fatalf("whatsappSvc.LoginWithQRCode() failed: %s", err.Error())
        }

        whatsappSvc.AddReceivers("Contact1")

        notifier := notify.New()
        notifier.UseServices(whatsappSvc)

        err = notifier.Send("subject", "message")
        if err != nil {
                log.Fatalf("notifier.Send() failed: %s", err.Error())
        }

        log.Println("notification sent")
}
