getting changes after Webhook

@Здравко, legend. Thank you. Root name space. did it.  

Yes, cache and go. Here is my Laravel solution using listFolderContinue() to retrieve or create a cache of the cursor.

public function listFolderContinue()
{
    $cursor = cache()->rememberForever('dropbox_stores_cursor', function () {
        return $this->listFolder()['cursor'];
    });

    $response = Http::withToken(cache()->get('dropbox_token'))
        ->withHeaders([
            'Dropbox-API-Select-Admin' => '<member_id>',
            'Dropbox-API-Path-Root' => '{".tag": "root", "root": "<id_of_root>"}'
        ])
       ->post('https://api.dropboxapi.com/2/files/list_folder/continue', compact('cursor'))
       ->json();

    if ($response['cursor']) {
        cache()->put('dropbox_stores_cursor', $response['cursor']);
    }

    return $response;
}

public function listFolder()
{
    return Http::withToken(cache()->get('dropbox_token'))
        ->withHeaders([
            'Dropbox-API-Select-Admin' => '<member_id>',
            'Dropbox-API-Path-Root' => '{".tag": "root", "root": "<id_of_root>"}'
        ])
        ->post('https://api.dropboxapi.com/2/files/list_folder', [
            'include_deleted' => true,
            'include_has_explicit_shared_members' => false,
            'include_non_downloadable_files' => false,
            'path' => '/Stores',
            'recursive' => true
        ])
        ->json();
}
