I created a new App, scoped folder, getting cursor is not workig

raiam As Здравко said, you'd need to be able to save cursors in order to keep track of changes over time. If you're calling filesListFolderGetLatestCursor after the webhook notification, that cursor will be for the point in time after the changes occurred, so you can't use that cursor to see those changes.

To start listing items, you should start with filesListFolder and iterate through with filesListFolderContinue as needed. Refer to the linked documentation for more information on how to use those. Ideally, you would store the last cursor you get each time, but you can start the entire listing, starting with filesListFolder, whenever needed.

As for the path, you can use the empty string "" to list the root for your app, and then check the results for the other path values you can use for other items.
