umm, can you cite a RESTful cloud storage API that&#x27;s consistently implemented between providers? If Dropbox&#x27;s API was RESTful would that save me any time using Google&#x27;s competing API? By the way, all these platform provide SDKs for you anyway and that&#x27;s usually a better way to use them.<p>When you start playing with the APIs from lots of different cloud storage folks (Dropbox, OneDrive, Google Drive) you see that they vary widely in concepts and capabilities.  REST or not building a client for one doesn&#x27;t really make you closer to using another.  Also Dropbox&#x27;s old API was REST and it doesn&#x27;t seem more portable (<a href="https:&#x2F;&#x2F;www.dropbox.com&#x2F;developers-v1&#x2F;core&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;www.dropbox.com&#x2F;developers-v1&#x2F;core&#x2F;docs</a>)
