Back to Index

Download a list of changes to a teamdrive. This example lists the changes for the team drive having id = "0AEd3EhGff2SaUk9PVA". The "pageToken" is obtained from a previous call to /drive/v3/changes/startPageToken or from the "nextPageToken" member of the previous call to list changes.
