Configure rlm_rest module to allow token authentication

Hi all, I'm working on the django-freeradius project. First of all, Thanks for the help on session limits feature. Now we wish to put restrictions on the API and therefore are thinking to go with Token authentication for each organization/ app. Can anyone tell me how to configure FreeRADIUS to allow token authentication, i.e., dealing with the requests having a token parameter? Also, it would be great to know if multiple tokens can be authorized, for ex., each user/ a group of users having a single token. Thank you, Rohith ASRK
