  title: Create a Function in a Function App and Verify It
  summary: Create a single function inside an existing function app, then read it back to confirm it exists.
  description: >-
    A focused authoring flow that writes one function definition into an existing
    Azure function app. The workflow performs an ARM create-or-update against the
    sites/functions resource with the function configuration envelope, then reads
    the function back by name to confirm it was persisted and to capture its
    invoke URL template. Every step spells out its ARM request inline — including
    the required api-version query parameter and the {properties:{...}} envelope —
    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.
