When the system boots, the UEFI firmware initializes and starts the ubios-udapi-server process. This process then communicates with the OS, which uses the services provided by ubios-udapi-server to interact with UEFI firmware components.

The is a core background process found in Ubiquiti's modern UniFi OS consoles, such as the Dream Machine (UDM) , UDM Pro, and Next-Generation Gateway (UXG) . It acts as the primary interface between the high-level UniFi Network application and the low-level hardware configurations of the device. Technical Functionality

Advanced users modifying the underlying OS (e.g., via udm-utilities or custom scripts) often find that ubios-udapi-server overwrites their manual changes. Because the server enforces the "Controller Truth," if you manually edit a file (like /etc/dnsmasq.conf ) and then trigger a provision in the UI, ubios-udapi-server will overwrite your manual edits to match the controller's database. ubios-udapi-server

You can also use the ubios-udapi-client to query specific statuses, such as the current status of DDNS services.
