Hi João,

It is certainly possible. Specifically, you can use values stored in
pseudovariables for authentication challenges instead of going to the
standard authentication database backing. Have a look at the pv_*
functions in the `auth` module, e.g.

https://kamailio.org/docs/modules/5.1.x/modules/auth.html#auth.f.pv_auth_check

Naturally, the values in these variables can be sourced from anywhere,
including an API call to a web server. You can make that call using the
`http_client` or `http_async_client` modules, for instance. You can even
parse a JSON result using the `jansson` module.
