You cannot. Wchatapi allows you to send 60 messages per minute, but if you send unsolicited messages where receipients do not want to receive, they will mark your number as Spam. Your Whatsapp number may get blocked. This service is strictly to send Transactional messages where receipients are expecting messages from you.
We haven't set any per day limit, with the rate of 60 per minute you can send more than 80,000 messages per day, but keep in mind this service is for transactional messaging only.
- You can connect only one Whatsapp Account, however you can scan QR from any whatsapp number any time, last whatsapp number used for QR scan is your sender number.
