Cannot authorize with RingCentral C# Client


Cannot authorize via C# Client


sample code below:


rc = new RestClient(Config.Instance.appKey, Config.Instance.appSecret, false);

var result = rc.Authorize(Config.Instance.username, Config.Instance.extension, Config.Instance.password).Result;


The error is "Request to https://platform.devtest.ringcentral.com/restapi/oauth/token failed with status code 400 (Bad Request)."



In case I try to use C# SDK, I always get following response error:



{


"error" : "invalid_grant",

"error_description" : "Invalid resource owner credentials."

}

Please check the password. The error message means your password is invalid.

There are two types of accounts for development:

Production credentials - this is used for production use 


Sandbox (test) credentials - this is for the test environment


When you are accessing anything with "devtest" in the domain, you should use your Sandbox credentials which are provided in the Developer Portal under the Credentials tab as mentioned by Tyler

Am I right to say that same password used to login to  https://developer.ringcentral.com ? I can log in there with my password. Even I can send sms via  API Explorer

There are two kinds of RingCentral apps: private and public.

Please double check. Is your app public or private? If it's private, only certain users can login. It might be the root cause of the problem.
