On a website that is based on a CMS engine, and is using a plugin for WhatsApp click to chat link i noticed the page title and URL included in the pre-filled message, which is very useful if you want to know from what website the request is coming:
If necessary i can provide the type of CMS and WhatsApp plugin page.
On the official WhatsApp faq page (https://faq.whatsapp.com/en/android/26000030/) i could not see any mention about this feature, so i was wondering if anyone know how this can be done? Because i have looked all over but could not fine a complete list of variable that could be used in the generated link.
I assume this could be done via java script.
