About the WhatsApp URL format
Links use https://wa.me/<number> and may include ?text= with a URL-encoded message. The number must be in full international form (digits only, no +). Recipients need WhatsApp installed (app or web). Test on mobile and desktop before you ship in a campaign. For https web destinations and GA4, use the UTM builder or Short URL—wa.me is for the WhatsApp app, not for tagging landing-page URLs.
Practical tips
- Keep the pre-filled line short: people can still edit the message before sending.
- Don’t use this for one-time secrets or passwords—anyone with the link can start a chat with that number.
- If you need a short web link on this domain, use Short URL for https pages; wa.me shortcuts are a separate use case.
