Basic Authentication in JSON Publishing

1. Problem
Publishing to JSON Alpha Server does not include an authorization token on the header of the request. The authorization token is included in the json body.
Is there a known authentication method that can be used when publishing the data to json server, e.g. basic authentication?

2. Server
ODK aggregate 1.7 on Ubuntu Server

3. Attempted fix
I have tried using basic authentication by pasting the authorization key on the Authorization token field but the receiving server doesn't find the token in the header.

4. Steps to reproduce
Configure publish to json server and view the request that is generated in the json server.
