To integrate WhatsApp onto our platform, you will need to provide us a mobile number that is not tagged to any WhatsApp account.
Due to WhatsApp's regulation and structure, in order for us to help you to send these WhatsApp messages on your behalf, you will need to relinquish the WhatsApp rights of the mobile number.
As such, you may need to get a 2nd mobile line or provide us with one that you are not using WhatsApp on. Do note that it has to be a post-paid line.
