Yandex.Disk REST API: Unable to upload file to disk. error 400 Bad request. what is wrong, how to download?

Question

Yandex

The application was registered, the token was received.
In accordance with the description
https://yandex.ru/dev/disk/api/reference/upload-ex... I
send a POST request using wget:

wget -S  \
     --header="Authorization: OAuth <ТОКЕН>" \
     --header="Accept: application/json" \
     --header="Content-Type: application/json" \
     --post-data="url=https%3A%2F%2Fget.wallhere.com%2Fphoto%2Fwomen-outdoors-women-model-portrait-depth-of-field-ass-tanned-painted-nails-black-hair-black-tops-lingerie-red-panties-girl-beauty-leg-computer-wallpaper-photo-shoot-thigh-undergarment-pin-up-girl-875506.jpg&path=disk%3A%2FBackuper%2F" \
     https://cloud-api.yandex.net/v1/disk/resources/upload

and everything seems to be correct?
but in response:

HTTP/1.1 400 BAD REQUEST
  Server: nginx
  Date: Tue, 10 Dec 2019 22:05:52 GMT
  Content-Type: application/json

PS: or does wget send POST somehow wrong??
UPDATE:
If you send parameters as part of the URL, it seems like something "rustles", but there is no positive result ...
here is such a request, through the URL,

wget  \
     --header="Authorization: <ТОКЕН>" \
     --header="Accept: application/json" \
     --header="Content-Type: application/json" \
     https://cloud-api.yandex.net/v1/disk/resources/upload?url=https%3A%2F%2Ffunik.ru%2Fwp-content%2Fuploads%2F2019%2F03%2F5c10c7476d9c1aa7f809.jpg\&path=disk%3A%2FBackuper%2Fphoto.jpg

fulfills the type successfully, downloads ...
but where is it not clear !?

$ wget  \

in response receives such json

{"operation_id":"a606e070d924b7e8e45af94d002004e560f885628f6e3758221f7af59b7c5599","href":"https://uploader9o.disk.yandex.net:443/upload-target/20191211T223927.785.utd.c48dm8nv9r0qh0lgb425q0g3g-k9o.191958","method":"PUT","templated":false}

but where the file itself is saved is not clear ... there is no file ANYWHERE on Yandex.disk.
something seems wrong, it apparently returns a URL for downloading by the PUT method, although it must download the specified file itself and save it to the specified location .... ??

Answer 1

Where to store backups after the death of Yandex.Disk?
