Datei von Webseite aus auf Nextcloud hochladen

Hello!

(how) is it possible to store a file from my website’s backend on my nextcloud?
E.g. by using an accesslink?

Thanks in advance
Daniel

It should be possible using WebDAV.
Google search: webdav linux nextcloud - Google Suche

Connect from your website to Nextcloud using WebDAV and copy/move the files to Nextcloud, the files will be listed under Nextcloud then.

Perhaps you could clarify how you are hosting your website, along with whether it is on the same machine as your Nextcloud. Thanks.
