Access And Topology
This group covers the entry point into the public API and the root tenant boundary. Read these methods in perimeter order: authenticate first, discover or admit the enterprise second, then inspect the enterprise-owned financial boundary through master accounts.
Access And Perimeter
Issue access token
Server-side entry point. Every backend integration begins by issuing a bearer token through the client-credentials flow. Nothing else in this group is readable until that access path exists.
