You can actually send a message without saving a contact. Using WhatsApp's click to chat: wa.me/263xxxxxxxxx?text=Hello Note: The phone number with country code and no preceding plus. Opening that link will launch WhatsApp (or WhatsApp web) to the user's number and the text "Hello" in the message field.

Doesnt seems to work for me. Get directed to a page saying I don't have WhatsApp installed (I do). Android v8, Firefox v68.6.

  That is because you are opening in browser. You have to set wa.me links to open in app. Open firefox settings, toggle 'open links in app'. (or) Open a chat with yourself in whatsapp. https://wa.me/your-number https://wa.me/your-number . You can spam anything here, it's personal and only you can see it. They send wa.me/number-of-person-you-are-contacting in that chat. Click on it and it will start a chat with person-you-are-contacting. All numbers MUST be in international format. Country code and number.

On Chrome Desktop Linux, it doesn't work despite me being logged into whatsapp web. Tries to do some xdg-open thing, but clearly that will never work considering whatsapp web has no registered protocol handlers... Looks like it is some half completed demo integration rather than production ready...

  Yeah it used to be quite hopeless unless you opened the link in a tab that had already loaded WhatsApp web. Now however, if you click the green button that says "CONTINUE TO CHAT" on the initial screen, it'll load a page with an option to download WhatsApp and another that's titled "use WhatsApp Web", just click on that one. Unfortunately, it will load a new instance of WhatsApp web in the current window even if you already have another open in another tab.
