• 400 BadRequest: The operation is impossible due to out of range arguments (e.g. tried to attack with more troops than you have)
• 401 Unauthorized: The logged in user is not allowed to take that action (e.g. not session owner)
• 402 PaymentRequired: The operation is impossible due to physical constraints (e.g. two regions aren't connected)
• 403 Forbidden: Not logged in
• 404 NotFound: Invalid guid provided (e.g. a bad session id)
• 405 MethodNotAllowed: Didn't use the correct HTTP verb (e.g. POST instead of GET)
• 406 NotAcceptable: The operation is impossible due to ownership constraints (e.g. trying to attack a region you own)
• 409 Conflict: Concurrent action detected (e.g. issued two conflicting attack requests at the same time)
• 417 ExpectationFailed: Trying to perform an operation, but the session is not in the required round state

Auto-generated by Visual Studio. Deals with authentication!

Requires the login details over HTTPS as x-www-form-urlencoded, which looks like this:

`grant_type=password&username="Stephen"&password="Devolan!"

It gives you back a token which you can then pass back in calls to other APIs in the Authorization header.
