I have been using the integration from sandbox environment to send free test sms'es and everything is working fine.This is the code that I am using
Dictionary<string, string> Params = new Dictionary<string, string>();
Params.Add("content", Msg);
Params.Add("to", MobileNo);
apikey.response = Api.SendSMS(apikey.api, Params);
Now I have a Developer central account and I only changed the API ID and now no SMS'es are going through.I was advised to use the username and password that was given to me - where do I use/put those credentials, please help!
