Dropbox Cursor Behavior
Hello, I'm trying to confirm cursor behavior. - Is it safe to assume that Cursor is an offset into a transaction log per account, which is a sequential record of changes as they occurred in the ac...
Thanks for your answer!
What I'm trying to understand is the consistent behavior of cursor as a pointer at a point in time. My use case is that instead of introducing the webhook complexity (leases, etc) into my application, I can just do a schedule scan every 15mins from the last cursor saved. If for some reason, during one of the scheduled scans, something failed. The next schedule can still pick up from the last cursor saved and we're not missing out on any updates.
- Is this the correct understanding?
- If during the scan, there are new files being uploaded/modified, these changes are appended, i.e. we can pick up those changes as the cursors progresses?
- I've read some documentation indicating that cursors do become invalid after some time, do we have an approximate amount of time?
Thank you so much for your time!

Dropbox Community ModeratorWhen you call /2/files/list_folder/get_latest_cursor, the Dropbox API will return a cursor for the corresponding account and path (if one is provided) at that particular point in time. So, if a call is made before any folder updates are done in that account, the cursor will be for "before" those latest additions.
Sending a request to /2/files/list_folder/continue with the cursor obtained from /2/files/list_folder/get_latest_cursor will return an empty "entries" array if no changes have occurred in the corresponding account or path (if one is provided) after that cursor was obtained.
A cursor could become invalid or stale over time. We don’t make any guarantees about how long a cursor remains valid, and we don’t have an approximate expiration window to share. Because of this, we recommend treating cursors as short-lived.
