PromoteVersion Method

Promotes a previous file resource version to be the current version.

Syntax

box.promoteVersion(fileId, versionId, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method promotes a previous version of the file resource specified by FileId to be the current version.

VersionId specifies the version that should be promoted. Box will make a copy of it to use as the new version.

Note that Box only tracks file versions for paid accounts.
