# Update Items in OneDrive

The connector's `update` fetch action updates the metadata of items in the OneDrive repository.

You can update the Access Control Lists (ACLs) for drive items such as files and folders. This means that you can grant a user permission to read or modify an item, or remove those permissions.

NOTE: OneDrive sends an e-mail message to each user who is granted new permissions. If you prefer not to send these messages, you can set the configuration parameter `UpdateAclSendInvitation` to `FALSE`.

To use the `update` action, you must construct some XML that specifies the identifiers of the items to update and provides the new metadata.

You must add the XML to the action as the value of the `identifiersXML` action parameter. The XML must be URL-encoded before being used in the action command. For example:

    http://host:port/action=Fetch&FetchAction=update
                                 &IdentifiersXML=URL-encoded XML

For more information about how to construct the XML, see Construct XML to Update Access Control Lists.
