Introduction

DigitalCX's ready-to-go integration between DigitalCX and WhatsApp's messaging platform. The WhatsApp public API is currently unavailable to the public and only accessible as part of their private beta program. In order to gain access to the private WhatsApp API we suggest using Twilio's API for WhatsApp Node.js Quickstart guide. This project provides you with the web hook logic that you can expose on top of your pre-existing Express.js server.

const express = require('express')
const whatsapp = require('dcx-whatsapp')

const app = express()

app.use('/whatsapp', whatsapp({
     project: {
        customerKey: 'customerA',
        projectKey: 'projectB',
        culture: 'en',
        apiKey: 'xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxxxxxx',
        env: 'cms'
    },
    sessionStorage: {
        host: '127.0.0.1',
        port: 6379,
        password: '********'
    },
    messages: {
        dialogOptionsOption: 'Press {optnumber} for {optvalue}',
        dcxNoResponse: 'No response from DigitalCX',
        applicationError: 'Something went wrong! Please contact support'
    }
})

app.listen(3000)
