A WhatsApp click-to-chat link opens a chat with your number when someone taps it, without them having to save your number first. The official format is:
https://wa.me/<country code><number>?text=<your message>
Links in the older api.whatsapp.com/send?phone= format open the same chat. wa.me is simply the shorter official form.
| Format | Best for | Tip |
|---|---|---|
| wa.me link | Bios, ads, emails, messages | Add a pre-filled message so the customer only has to press send |
| QR code | Anything printed, or a screen people look at from their phone | Print it at least 2 cm wide and test it from arm's length |
| Website chat button | Every page of your site | Keep it in the bottom-right corner where people expect it |
Make one link per place, each with its own pre-filled message: "Hi, I saw your Instagram post", "Hi, I scanned the QR code at your shop", "Hi, I found you on Google". When the chats arrive you can see at a glance which channel is working.

Yes. Add ?text= followed by the URL-encoded message to the end of the link. The customer sees the message typed in the chat box and can edit it before sending.
Yes. On a computer it opens WhatsApp Web or the WhatsApp desktop app. On a phone it opens the WhatsApp app directly.
