Other BOX APIs - BOX Account

We have the BOX snap pack, and use many of the pre-built BOX snaps for writing files, etc. with an associated BOX account for our system. BOX has many other APIs that don’t have pre-built snaps though, such as administrative APIs for managing domain whitelists, etc.

I can probably just use the REST API snaps for the other types of APIs, but need to be able to leverage the same BOX account used by the BOX snaps. Is there a way to somehow leverage the BOX account with the REST API?
