[YANDEX] Short URL API not working

[shmugoh]

I've been trying to access the Yandex Short URL API as of lately (since sv-dlp doesn't really short Yandex links by the API. It just shorts them by parsing the panorama on a long link) but it requires a few tokens - csrfToken isn't a problem, as Yandex will generate you one if you input an invalid one, but I'm not sure about the s and sessionId.

By using ones that I've already generated by myself (as seen in the picture), it returns me a 403 error with the following message

Help is appreciated
