WhatsApp API vs QR connection: which should I use?
Advertz supports two ways to connect WhatsApp.
Official WhatsApp Business API (Link Meta WhatsApp)
- Approved by Meta — the safe choice for broadcasts and automation at scale
- Many agents on one number, chatbots, templates and delivery reports
- Template messages are charged by Meta per delivered message; replies within 24 hours of the customer’s last message are free
QR connection (Add WhatsApp by QR)
- Scan a QR code with the WhatsApp app on your phone — quick to try
- Best for testing and low volumes
- Not suitable for bulk sending: unofficial bulk messaging can get a number restricted by WhatsApp
Our recommendation
Start with QR if you just want to try the inbox, and move to the official API before you run campaigns. See the guide “WhatsApp Business App vs API” on our website for a full comparison.
