Url which the server should redirect the user to after obtaining
authorization.
transport
com.google.api.client.http.HttpTransport
Methods
complete(String authorizationCode)
publicCredentialcomplete(StringauthorizationCode)
After the user has authorized the request, the token or code obtained should be passed to this
complete function to allow us to exchange the code with the authentication server for a Credential.
After the object is created, the developer should use this method to interrogate it for the
authorization URL to which the user should be redirected to obtain permission.
