Three settings, all global (not per kitchen location):

• API Token — your Root Planner token; enables the integration (Configuration > Root Planner tab, and the Root Planner integration tile).
• Webhook Secret — the shared secret that protects route updates coming back from Root Planner (same places).
• Version — Development / Beta / Live; which Root Planner environment is used (super-admin system Config page only, and the onboarding wizard's "12. Root Planner" step).

In the client Configuration screen the Root Planner tab is listed within the Business section.
