Server-based Login?

Server-based Login?

I am making a simple server application that creates a Simile Timeline using a Zoho-created JSON file. I want to get the JSON from a private application. Is there any way to pass the username/password through? I have tried all variations of SharedBy=myusername but it doesn't seem to work.

I don't want to make it public. The webpage will only be accessible within an intranet.
