send message by viber or whatsapp programmatically

问题:

I have a system with some members. my members should receive one message each day. I want to send this message via Viber or whatsapp (or if there are others app like them). But I dont want to send messages one by one. I want to send by asp.net c# code. Is there any document or API for this aim?
