 `single_file_name` | `string` | This is a narrowly-scoped permission that allows the app to access a single file in any repository.

When you set the `single_file` permission to `read` or `write`, this array can store the paths for up to ten files that your {% data variables.product.prodname_github_app %} will manage. These files all receive the same permission set by `single_file`, and do not have separate individual permissions.

 You can select permissions in a query string using the permission name in the following table as the query parameter name and the permission type as the query value. For example, to select `Read & write` permissions in the user interface for `contents`, your query string would include `&contents=write`. To select `Read-only` permissions in the user interface for `blocking`, your query string would include `&blocking=read`. To select `no-access` in the user interface for `checks`, your query string would not include the `checks` permission.
