Hi! You can absolutely use Zapier to manage files on cloud storage services like Dropbox, Google Drive, or even Amazon S3. That’s what we do: we connect to the APIs of various platforms and let you make automation, called Zaps, that connect them. Is there a specific thing you want to accomplish? Maybe we can point you in the right direction if we know more.

FYI: Zapier has a Webhooks app that can be used in a Zap to leverage another app’s API, if that’s what you’re looking for.

@jpot  My company has a web application where the users can create their Folders and files structure (PlanRoom). The new feature that my company wants to offer our clients is the possibility to sync that planRoom to their favourite clouds. 

I will appreciate you if we can talk I can explain to you what exactly I want.
