Returns information about the quality of the request. Use this to debug OAuth issues. If client_id or token is null, then something has gone wrong with your request (Splitwise is failing to recognize either your client app or the specific logged-in user).

{
  "client_id":null,
  "token":null,
  "request_url":"https://splitwise.com/api/v2.1/test",
  "params":{}
}
