Issues with 2/files/list_folder/continue & cursor

Question

I have a web app that does the following in order:
&nbsp;
1. Login user via "login via dropbox" link
2. Get and save latest cursor
3. Call 2/files/list_folder/continue as needed using latest cursor, saving new cursor after api call
&nbsp;
Now, no matter what changes are made to the app folder, *ALL* changes are returned when calling 2/files/list_folder/continue, not just latest changes.
&nbsp;
Am i doing something wrong or out of sequence?

Thanks! I just tried this, and I can't seem to reproduce this issue with this code though.

Are you sure the first call is succeeding? I don't see any error handling in this snippet.

Also, how are you copying $new_cursor to $cursor? I don't see that in this sample either. Are you sure that's working properly?

Hi Greg,
Sorry for the lack of information.
&nbsp;
I'm using PHP with no library (just CURL)
&nbsp;
Snipper
&nbsp;
$data = '{"cursor": "' . $cursor . '"}';
            
$ch = curl_init('https://api.dropboxapi.com/2/files/list_folder/continue');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $token, 'Content-Type: application/json'));
$json = curl_exec($ch);
$result = json_decode($json, true);
        
$new_cursor = $result['cursor'];
There are no errors. However, the next time i call list_folder/continue with the new cursor, i get a history fo all changes previously. Not just recent changes.
Thoughts?

Hi Greg,That's just a snippet in a class file. So essentially what im doing is this1. Log user in, get latest cursor and save to database locally2. Once a user makes changes, a webhook is sent and the locally stored cursor is used for the list_folder/continue call3. Update cursor for userNow when another change is initiated, making a call with the new cursor still shows ALL changes, not just latest.I think i'm just using the wrong cursor, but need to confirm.Should I..Make API call then save cursor given by list_folder/continueOrMake list_folder/continue API call, then do another to get_latest_cursor and save that cursor.

Disregard. I was not saving the latest cursor properly. I was using the wrong column name "user_id" vs "id" in the user table.Sorry for the trouble and will add error handling asap.
