You need to create an interface for me to do the messaging delivery to whatsapp.
I understand whatsapp do not have API, but i believe there is something so call indirect through whatsapp web. Please advise.
Attach picture for the system architecture prototype development.
I have already developed this application using WPF and C#. The app can send both text and multimedia messages thru we.whatsapp. Text me if you need a demo.
