The JavaScript API is meant to be dropped into an existing website. It will let users drag and drop files into your website and have them seamlessly uploaded into customizable folders within their Box account.
Due to the security restrictions applied (for good reason) to the JavaScript runtime within web browsers, this API is not allowed the same ease of use as some other APIs.
Most notably,
- each user will need to submit their credentials each time (unless you use cookies)
- special effort needs to be made to proxy requests or embed the js in an iframe. (TODO -- blog post)
All users of the Box API are required to register for an API key. Instructions for this as well most other questions you may have may be found at http://developers.box.net/
