I have about a site with about 50 customers. They each have a user profile. They want to be able to automatically include their images which they store on DropBox in their profiles.
My idea is to make a Dropbox api that scans their folders (with their permission) and just include the images in their profile. I already know how to link directly to their images as long as I have the url.
I set up the Ruby API. Only question is : Do they have to authorize my app every time I try to access their images?
I want to somehow store authorization information for each client, then just reuse that info and access their images through the Ruby API. Is this possible? How is it done?
I think if I can just get past this authorization hurdle I can take care of the rest.
You can definitely do this. Just store the access token at the end of the OAuth flow and reuse it. From https://www.dropbox.com/developers/core/start/ruby:
The access token is all you'll need to make API requests on behalf of this user, so you should store it away for safe-keeping (even though we don't for this tutorial). By storing the access token, you won't need to go through these steps again unless the user reinstalls your app or revokes access via the Dropbox website.
