Team-linked applications using the Business API are able to poll for a variety of changes to the team - including changes to team content, membership, sharing, and more. Team-linked applications have mechanisms to poll for these and other types of changes, as described below. In general, most applications should look up these attributes as-needed, rather than poll for them specifically. Some endpoints, such as /sharing/list_file_members,may employ optional cursor and continue patterns for fetching large result sets, but may not support polling for change via cursors. Note that the methodologies described above will allow you detect changes to files themselves, but will not indicate changes to sharing settings or other metadata. Note that webhooks will trigger for any changes to files the application has access to - so if your cursor is to a specific sub folder, not all notifications may be relevant to your app. Read more about using Dropbox webhooks here. By saving the cursor for users, your application can then call /files/list_folder_continue to read the associated change when it receives the hook. With webhooks configured, Dropbox sends an HTTP POST with the user IDs when changes occur. Instead of rapidly polling - which would be very inefficient if done 24/7 - Dropbox can instead notify applications when users’ filesystems change. Notificationsįor server-side applications that need background notifications in realtime, Dropbox also provides webhooks for user file changes. This methodology will let you respond quickly and efficiently to changes. Once long poll signals change, you can use /files/list_folder_continue to list the updates. Passing your cursor to the call will simply block until a change is detected (or its timeout occurs). These client-side applications should instead leverage /files/list_folder/longpoll for these cases. Waiting for User Changeįor interactive applications that need real-time notification of a change in Dropbox, rapid polling is inefficient. If your application is only interested in changes going forward, the /files/list_folder/get_latest_cursor will return the most recent cursor, without needing to iterate through list and continue calls. If the folder itself that the cursor refers to is deleted, the call will return a 409 path error. This indicates you should issue a new call to /files/list_folder and iterate to obtain a new cursor. A call to continue with an expired cursor will return a 409 reset error.

Thus, while polling, be sure to always update to the latest returned cursor - even if no results are returned. PollingĪs a result of this property of folder cursors, storing the cursor value allows you to poll for changes to the target directory.įolder cursors are long-lived, but may expire if unused for an extend time. The ListFolderResult returned in the call includes indication of file change (add/modify), folder change, or deletion. Your list /files/list_folder_continue with a given cursor may return 0 results with has_more:false now, but calling it after modifying content in the folder will return those changes.
Folder cursors are pointers to the folder at a particular time - and thus you may use a cursor to fetch changes that occurred after the time the cursor value was issued. However, these cursors are not only for useful pagination. Successfully enumerating all files in a folder requires calling /files/list_folder_continue with each successive cursor string until has_more is false. This call also returns the has_more boolean, indicating if more results are available, as well as a cursor. The /files/list_folder API call is used to list content with a Dropbox folder. Dropbox provides tools for developers to poll, wait for, or be notified of changes to users files.
