# Repositories API

## List repository tree

Get a list of repository files and directories in a project. This endpoint can
be accessed without authentication if the repository is publicly accessible.

This command provides essentially the same functionality as the `git ls-tree` command. For more information, see the section _Tree Objects_ in the [Git internals documentation](https://git-scm.com/book/en/v2/Git-Internals-Git-Objects/#_tree_objects).

```
GET /projects/:id/repository/tree
```

Parameters:

- `id` (required) - The ID or [URL-encoded path of the project](README.md#namespaced-path-encoding) owned by the authenticated user
- `path` (optional) - The path inside repository. Used to get contend of subdirectories
- `ref` (optional) - The name of a repository branch or tag or if not given the default branch
- `recursive` (optional) - Boolean value used to get a recursive tree (false by default)
