Keep keys server-side; never embed them in client code. Requests with a missing or invalid key fail with HTTP 401 (unauthorized).
Path Parameters
Knowledge base ID, from List Knowledge Bases. For a scoped key, copy the ID from the Dify URL.
ID of the metadata field to delete. See List Metadata Fields.

Success.
