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 hash digest, etag, and name as the original.

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



Path Parameters

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

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.
