I have an FTP problem discussed here
(http://forum.lazarus.freepascal.org/index.php/topic,27488.0.html) but
this is a seperate question, spawned in light of my FTP difficulties.

These days, with the ever growing popularity of Cloud services like
Copy.com, Dropbox, Google Drive etc, most (all?) of which do not allow
FTP transfer to them or from them, many Internet threads refer to FTP
as a dying technology. Whether that be the case or not, I am curious
to know if there is a way within Freepascal to send and receive files
to and from cloud services rather than using FTP to transfer files to
a server directly? In other words, if your application form takes the
username and password from the user for his\her cloud service, like
Dropbox, is there a way to move the files to and from it?

yes it is. Its not simple and there is no ready component to help you
out so if you delve in these waters you are pretty much alone. In
short you use an existing http library (synapse, indy, lnet etc) and
you build on top of that all the calls, encryption and authentications
the site require to allow you to interact with it. This is the only
way to do it. Some site might give you some kind of API or SDK that
you can use for various languages eg mega.nz has a library for C/C++
that you can use.

Those services usually provide a web service API with OAuth
authentication. So you just have to do it as how their protocol is
documented.
