webhook not getting file or folder information like added or deleted from dropbox

[aalok]

Currently, I am using dropbox-Php-SDK Kunal Verma. webhook URL added in dropbox console. at the change of file or folder, the webhook gets active.

  $listFolderContents = $dropbox->listFolder("/",[ "include_deleted"=> false,"include_has_explicit_shared_members"=> false,"include_media_info"=> false,"include_mounted_folders"=> true,"include_non_downloadable_files"=> true,"path"=> "/",'recursive' => true]);

        print_r($listFolderContents);

        $cursor = $listFolderContents->getCursor();

        $listFolderContinue = $dropbox->listFolderContinue($cursor);

        $post_dump = print_r($listFolderContinue, TRUE);

        $fpost = fopen('logs.txt', 'w');

        fwrite($fpost, $post_dump);

        fclose($fpost);

then I am trying to get the cursor and send it to listFolderContinue function but getting blanck entry 

response :

Is this output just the $post_dump that you're saving to logs.txt? If so, it looks like that only includes the result of the listFolderContinue call, but not listFolder. While you do need to implement both, in this case it's possible all of the results are being returned by listFolder, and so there's nothing left to return by listFolderContinue. You should always check 'has_more' to see if you need to call back for more entries or not.
