See http://0pointer.net/blog/the-new-sd-bus-api-of-systemd.html and
have a look at the sd-bus.h header file:

https://github.com/systemd/systemd/blob/master/src/systemd/sd-bus.h

To read properties we have the sd_bus_get_property() and related
convencience functions. There's currently no nice documentation
available for them, hence consult the sources of systemd for details.

This is an internal function of systemd, and is not part of any
API. It should not be used in external programs.

The systemd D-Bus API "sd-bus.h" is a public API now, see the blog
story linked above. Along with some other APIs it is exported by
libsystemd.so. However, calls like unit_name_from_dbus_path() are not
part of that library and not accessible externally.
