Returns an OAuth 2.0 token using HTTP GET.
Note: there is a corresponding operation that performs the same action using HTTP POST: POST /oauth/oauth20/token. For information on why you might choose one or the other, see OAuth Operations: GET or POST?
This operation works essentially the same as the corresponding POST operation. For information about using it, refer to POST /oauth/oauth20/token.
Note: This operation might be disabled by a platform security setting in the Akana Administration Console. If the GET operation is disabled, the request is rejected with an HTTP 401 response code and this error message: The request is invalid. In this scenario, you can use the POST operation, which is more secure since information is not sent in parameters.
