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?
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.
