What QR mode actually means
Connecting Option CRM is similar to linking WhatsApp Web. Your phone owns the account; Option CRM uses an authorised linked-device session to send and receive.
Remember
Your WhatsApp or WhatsApp Business account remains on your phone.
The Option CRM server must stay online while campaigns are running.
Closing the browser does not necessarily stop a running backend campaign—use Pause or Stop.
Large-scale promotional messaging is more reliably supported through the official Meta Cloud API.
Remember
Use a dedicated WhatsApp Business number, enable two-step verification and keep a backup of important business data.
Avoid
Never scan a QR supplied by an unknown person and never share your Option CRM session folder.
