How does a WhatsApp wa.me link work?

A wa.me link utilizes WhatsApp's official Click-to-Chat API. When a user clicks your link or scans your QR code, WhatsApp automatically opens a new chat with your specified phone number and pre-populates your custom message.

Do customers need to save my phone number to message me?

No! The main benefit of a wa.me link is that customers can start a direct WhatsApp conversation without saving your phone number in their phone address book first.

Can I use the WhatsApp QR code on print marketing?

Yes. You can download the QR code in vector SVG or high-resolution PNG format, making it ideal for business cards, flyers, restaurant menus, packaging, and in-store displays.
