Job description:

----------------------------------

We need the ability to send and receive WhatsApp messages from a server so that WhatsApp can be seamlessly integrated with other communication channels such as SMS or email into an own messaging app.

The job consists of 3 parts

1) Android App

An Android app has to be developed, which basically consists only of a webview in which WhatsApp Web is hosted.

When the app starts, the WhatsApp Web QR code should be displayed so that the app can be connected to a WhatsApp account on a second smartphone.

Then the app must be active 24/7 (similar to a kiosk mode) so that all incoming messages can be received at any time and the app itself can receive messages from a remote server. The smartphone on which the app is running then is used only for running this app - like a mini-messaging server.

2) Javascript code injection into WhastApp Web

Javascript code is to be developed which will be injected into the WhatsApp web code by the Android app from point 1. The code must send all incoming messages and also the history of the corresponding chats to a remote server, including all media such as images, documents and videos.

Furthermore, the code must be able to receive messages including media from a server and send them via WhatsApp.

3) Messaging App in Javascript

A messaging app is to be developed in javascript. Basically this app should be a complete WhatsApp Web clone that contains all the features known from WhatsApp, such as sending media.

This app must also be able to display chat history stored on the server in WhatsApp-style.

The app must be able run in all popular browsers, or in a webview in Android or IOS apps.
