Hi,
I want to know that can you develop an application that can send messages , Images, Videos, Voice Notes in Bulk volume on audience's Whatsapp number ?
e.g if I want to send SMS to 1 Lac people, I upload their mob. no. then application will search if number is at whatsapp or not then it will start sending messages to their number then we can have acknowledgement of delivery percentage , numbers which is non-Whatsapp number.
Also if we can receive a reply for the same.
