FAQ
Will WhatsApp ban my number?+
Not if you keep volume reasonable (< 500/day), send only to customers who ordered, and keep spam reports near zero.
Should I graduate to Cloud API?+
Yes, once you cross ~500 messages/day. Cloud API has official support, templates, and no ban risk.
Can I use the same number on my phone?+
Yes — WhatsApp Web is a linked device. You can still use WhatsApp on the phone.
