What is the pourpose of &source=, &data= and &app_absent query strings parametres in the whatsapp url (https://api.whatsapp.com/send?phone=XXXXXXXXXXX&text=&source=&data=&app_absent=) ?
It is possible to track WhatsApp message's source filling these parameters ?
If it is, where I can see those information ? On Whatsapp business App ?
&app_absent=1 Is used to replace the "Continue to Chat" button by "Download" button to allow user to download WhatsApp for current OS.
