$30-250 USD
Pagado a la entrega
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.
