Hello!

I have difficulty to start using RingCentral Api.

My application type is "Public" and my Platform Type is "Server/Web".

I am using C# to authorize but I got Bad Request and the following answser:

{

"error" : "unauthorized_client",

"error_description" : "Unauthorized for this grant type",

"errors" : [ {

"errorCode" : "OAU-251",

"message" : "Unauthorized for this grant type"

} ]

}

I saw that it is because my Platform Type (Server/Web) does not support password grant type and I need to use "OAuth 2.0 Code flow".

I tried to find an example using "OAuth 2.0 Code flow" in C# but did not find anything. Could you please give me an example that works for me?

Thank you very much!
