How can I open a whatsapp chat from mobile webpage?

Question

I am looking for a way to open whatsapp chat through a webpage opened in mobile browser. Like if a user opens my webpage using a smart device and clicks on a link, it should open the whatsapp chat application on the smart device.

I did some research and found that using <a href="whatsapp://send?abid=&text="></a> does exactly that, but I am unclear about abid. Its an address book ID, but how to get that id, like if the user has my number in its contact list, how to get the id?

And I also want to give an option to the user to add my number to its contact list if its not already there, how can I do that?

I don't think you can get the abid with javascript in a website, if you are using PhoneGap or something like that you can search for a plugin. — InvisibleUn1corn

It is now possible. WhatsApp's click to chat feature allows you to begin a chat with someone without having their phone number saved in your phone's address book. To use this feature, create your own link.

Basic Usage: https://wa.me/whatsappphonenumber
Example: <a href="https://wa.me/1XXXXXXXXXX">Click to chat</a>

Link with a pre-filled message: https://wa.me/whatsappphonenumber?text=urlencodedtext
Example: https://wa.me/1XXXXXXXXXX?text=I'm%20interested%20in%20your%20car%20for%20sale
