I am building a RingCentral application on a server that for security purposes will not take any POST/GET variables other than a specified one. When I try to authenticate, the response url which contains the code as a query string variable with the variable name "code", causes my server to stop the script from running. I would like to change the variable name in the response url that contains the authorization code. Is this possible? Can it be done using response_type? RingCentral specifies on the API that response_type must be set to "code" so I'm not sure. Any advice would be highly appreciated.
