  title: Inspect a Function App and Issue an Admin Token
  summary: Read a function app, list its functions, and issue a Functions admin token for the runtime API.
  description: >-
    A read-and-authorize flow for tooling that needs to call a function app's
    Kudu/admin runtime API. The workflow reads the function app resource to
    confirm it exists and is running, enumerates its functions so the caller
    knows what is deployed, and finally issues a short-lived Functions admin
    token that can be presented to the runtime admin endpoints. Every step spells
    out its ARM request inline — including the required api-version query
    parameter — so the flow can be read and executed without opening the
    underlying OpenAPI description. All requests are authorized with the
    azure_auth OAuth2 bearer token carried by the Azure Resource Manager
    endpoint.
