My girlfriend uses Whatsapp on Blackberry. As this is not supported anymore after 2017 I hope to somehow find a way to code an App or a Web App for her, so that she can use her beloved Blackberry.
I found some older Threads about some Whatsapp API's but they seem to have legal problems. Questions:
I also though of a second way: Installing Android on a VM in my Datacentre in Paris with a Fixed IP. Configuring Whatsapp on this device and than coding an app, that is something like a Public API on this Device (With authentification of course) and then Coding an App for the Blackberry or a Web App that connects to the API on the Android Device in my Data Centre....
Any other suggestions?
As a basic recommendation, she might need to get an Android device... if either of you financially can.
On the other hand you might want to look at this API which is an interface to WhatsApp Messenger

I have yet to use it myself but it has a very neatly Whatsapp integration guide

EDIT:
Also This library might help if you know python and want to make an private API for a custom application
