The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[Stefan Winter <stefan.winter AT restena.lu>]

Hello,


the link for any given OS / profile / language combination is displayed 
after you hit the Download page (see attached for an example, grey area 
in the flow text).


That link is an API call, and is usable unchanged since CAT 2.0.0. It 
will continue to be supported until at least 3.0.0 as semver suggests.


Here is the call for the example given:


https://cat.eduroam.org/user/API.php?action=downloadInstaller&lang=en&profile=5&device=linux&generatedfor=user&openroaming=0


Pretty much all of the elements are hopefully self-explanatory.


Greetings,


Stefan Winter
