Trying my hand at outlook sync add-in. I'm trying to ascertain deleted tasks since last
- How to find deleted tasks since last sync in Outlook. Currently I'm saving all task ID's, and check whether some have gone missing since last sync. Is there a better way, with info available in the Outlook model?
- does Toodledo have a Hashfunction, or a way to verify if the two distributed copies of the tasks are equal. (as a final check after syncing if they are equal). For example a MD5 hash of some fields, that I can perform locally as well?
If you are downloading every task, every time and looking for missing tasks, you are definitely doing it wrong and using too much network bandwidth. You should be able to sync with only transferring the changes.
To fetch only those tasks that have been deleted, use the "tasks/deleted.php" API call and pass in the timestamp from the last time you checked.
