# Create an evaluation set using a path ID

> Create an empty set using the path ID; success returns JSON null

Available only with the development UI enabled, such as `veadk web` or `adk api_server --with_ui`; the default `adk api_server` does not expose this endpoint

This deprecated endpoint creates an empty set using the path `eval_set_id` and returns JSON `null` on success

See the [corresponding evaluation endpoint](/productions/api-reference/preview/en/agent-api-server/create-eval-set) for the replacement and its complete requirements
