Whatspp button is not working on browsers?

Question

I'm using a whatsapp button on my website, but when I click on it, the message to send appears, and when I click on it, the html appears.

I've seen in some forums that it's a bug in the whatsapp API, is someone else going through it?

Answer 1

This page is broken due to empty content-type response header, browser expects something like text/html value to start rendering the response.

Official Whats Up doc suggests to use

https://wa.me/1234567

link format for send message links, where 1234567 is tel number.

You can update generated code to use this format.
