Add unwrapping requests from data, for instance each request for tokens provides response with token as root key. So in general it looks like each endpoint may enclose response with endpoint API. This information is useless for the client and binding should automatically unwrap response.
Some request are by definition parametric because of parameters are directly embedded in URI. However requests where parameters are optional are not implemented. As a reference for this issue check following hyperlink.
Following API binding has not been tested with tests:
Should automatically handle tokens refreshing and caching. Refreshing should be made only if token has expired.
