# Get file metadata

> Retrieve metadata for an authorized workspace file.

Supply the exact resource `key`. Workspace ownership is checked before metadata is returned. Invalid keys return `400`; unauthorized keys return `403`. The response contains the key and metadata, which can be null. This does not download file contents.
