Can I try the User Experience?

Of course. We have a demo site where you can feel the WhatsAuth service.

In https://demo.whatsauth.com/en/demo you'll find standard usage implementation where a WhatsApp button and a QR code are displayed for you to scan or click. Just hit the green button!

It will show you the following "form":

Once you send the preset message you'll see the phone number and profile name instantly in the form and a JSON representation as well:

The demo could be also used for more complex scenarios such as:

• QR Only: https://demo.whatsauth.com/en/demo/qr
  Only QR is shown to scan (not a clickable button)
• Button Only: https://demo.whatsauth.com/en/demo/btn
  Only the Button is shown.
• Restricted Number:  https://demo.whatsauth.com/demo/otp/+987654321
  In this case, the generated code (as QR or button) will only validate when scanned or clicked by the specified phone number, typical 2FA usage. Remember to change your phone number in the URL for proper testing.
