How to send message or even image to service whatsapp with qt?
Some C / C ++ Whatsapp API or even in Qml?
Whatsapp has no public API. that forces you to go through the application to use the service. You might be able to use https://web.whatsapp.com/ as a gateway to the service but it's kind of a hack and still forces you to have the app installed and running
Something like this. It was a chrome extension.
maybe waboxapp (link removed) is what you are looking for. It's a WhatsApp API as a service, using your own phone number.
It can be integrated with a simple http request.
