api viber/WhatsApp send bulk message -- 2

I need API to send messages to millions of recipient in Viber and Whatsapp. The API must : - get list of phone numbers and check who is active in Viber and Whatsapp - Upload contacts via XLS, TXT, CSV - Type texts or upload images - Generate report after sending with full status (Delivered / Seen). - Prevent Whatsapp and Viber from stopping the registered tel number after sending a few hundred messages. - Good if this program will make screenshots! Please bid only if you can handle this project and you are experienced in this field.
