Storage API Help - editing a document

Hi,

This may be a basic question.

Once a request is sent to via the Storage API to get a list of documents, how do you actually act on that list? How do you take the document ID and the document URL and open those up in a browser window for someone to edit?

This is mentioned a few times in the API but it doesn't look like there is an explicit REST API Method to edit an existing document on Zoho's servers. There is one to edit a new document.

Thanks for your help,
Avichal
