Integrating Next Cloud with Laravel

I have a project that'll come in the next few weeks where the client wants to have a NextCloud integration for his document management.

I had a look on the next cloud doc and have to admit I was a bit lost. It seems to use WebDav protocol, which I googled and I am now okay with that.

But neither the doc nor google is really crystal clear on how it works. I may be searching at the wrong place or with wrong keywords. I'm used to work with RESTful API so webdav looks a bit ... old. It seems everything has to be manager through XML.

If someone knows good resources or if someone already use nextcloud with Laravel, i'll be down for hearing your experience with it and any advice is welcome.
