    Revert file version


    Revert to a previous version of a file.

    If previous versions exist, this method can be used to promote one of the older versions to the top of the version history.

    This actually creates a new copy of the old version and puts it at the top of the versions history. The file will have the exact same contents as the older version, with the the same SHA1/etag, and the same name as the original.

    Other properties such as comments do not get updated to their former values.



    Path Parameters

    stringin pathrequired

    The unique identifier that represent a file.

    The ID for any file can be determined by visiting a file in the web application and copying the ID from the URL. For example, for the url https://* the file_id is 123.

    Query Parameters

    string arrayin queryoptional

    A comma-separated list of attributes to include in the response. This can be used to request fields that are not normally returned in a standard response.

    Be aware that specifying this parameter will have the effect that none of the standard fields are returned in the response unless explicitly specified, instead only fields for the mini representation are returned, additional to the fields requested.
