WhatsApp QR code questions
How do I write the wa.me link correctly?
Use https://wa.me/ followed by the full number in international format without plus signs, spaces, or leading zeros — for example https://wa.me/15551234567. Add ?text=Hello%20there to pre-fill the first message.
What happens when someone scans it?
WhatsApp opens with your chat ready and the pre-filled message in the input box. The scanner reviews it and presses send. On phones without WhatsApp installed, the browser offers to download it first.
Why put WhatsApp behind a QR code?
Typing a phone number into a contact form is friction; scanning is not. Shops put the code at the counter, sellers print it on the box, and service teams stick it on machines so customers reach the right chat in two seconds.
