After a very little research on this, I found out that maybe a cloud storage provider with the simplest MediaFire API, which offers really easy interaction through RESTful services. You can see the API documentation . I haven't started working with this API yet, but it looks like it provided all the basic functions.
The API served by Box seems to be pretty simple as well. It uses OAuth 2.0 , which makes it more secure. See the developer site .
The 4sync SOAP API is also very simple. There is not much documentation there, and the samples on the website look from an older version, but it is very easy to use anyway. See the documentation here .
